Description

Technical field

The invention relates to the creation of textbooks that clearly explain the phenomena of nature. It can also be used for recreational purposes in park ensembles, Disneyland, etc. In particular, the invention relates to a method for simulating a natural geyser and a device for its implementation.

State of the art

A known method of simulating the process of eruption of a natural geyser and a device for its implementation, comprising a geyser camera located at a considerable depth below the surface of the earth [a.s. 461700, A.G. Merzhanov, A.S. Steinberg, G.S. Steinberg,]. The chamber is equipped with a heater and a pipeline through which cold water is supplied to it. A vertical channel emerges from the chamber, through which a mixture of boiled water and steam is discharged. The upper end of this channel is located on the surface of the earth or at a small height above it.

To increase the amount of water discharged, in addition to the described method, a relatively small immersion of the inlet end of the geyser channel is used below the level of the top cover of the geyser chamber [a.s. 2015574, U.I. Goldschleger, A.G. Merzhanov, A.S. Steinberg, G.S. Steinberg].

Thus, after the start of boiling, the steam formed in it, the amount of which is continuously growing, at first has no way out of the chamber. Steam presses on the surface of the water in the chamber and non-boiling water begins to be squeezed out of the channel. Hydraulic resistance to the movement of water in the channel increases the pressure in the chamber and increases the temperature in it. After the water level in the chamber decreases to the level of the inlet end of the geyser channel, a significant amount of steam begins to flow into the channel. The pressure in the geyser decreases rapidly and the eruption begins. A common drawback of these and similar methods is the placement of a chamber with heaters deep underground, i.e. significantly lower than the output end of the geyser channel. While the diameters of the channels of even powerful geysers do not exceed ID-20 cm, the diameters of the chambers of even small artificial geysers should be of the order of several meters. Drilling even relatively shallow wells of this diameter is extremely difficult and extremely expensive. No less difficult is the subsequent placement of geyser chambers in them, which are specialized steam boilers equipped with powerful heating devices (burners or electric heaters), systems for measuring temperature and pressure in the boiler and controlling the heating of water in it.

It is these shortcomings that explain the fact that, despite the fundamental simplicity and spectacular spectacularity of the eruption of a natural geyser, combined with the cognitive value of this phenomenon, artificial geysers have not yet been created. They are not shown in parks, schools, or playgrounds such as Disneyland in Los Angeles. The few small-sized geyser models of the type shown at the Exploratorium Museum in San Francisco have a negligible energy reserve and are characterized by an extremely small (about 1 meter) water discharge height, i.e. practically do not imitate the natural geyser process.

Disclosure of invention

The aim of the present invention is a method for simulating a geyser process and a device for its implementation, free from these disadvantages.

A geyser chamber (boiler), in which water is heated and boiled, is placed in a small depression in the ground or on its surface. The geyser chamber is heated by the combustion products of natural fuel (gaseous, liquid or solid) or powerful electric heaters. The supply of cold water to the geyser chamber is carried out through a pipeline having a valve. The combustion of gaseous or liquid fuels in a mixture with air is carried out using a burner. Combustion products cooled as a result of contact with the heating surfaces of the geyser chamber are emitted into the atmosphere through a chimney. Like standard water heaters with high steam pressure and steam boilers, the geyser chamber is equipped with temperature control devices (thermocouples and thermometers), steam pressure (pressure gauge) and water level (gauge glass). The exit of hot water, steam-water mixture and steam from the geyser chamber is carried out through a pipe connected to the outlet pipe, which, in turn, is connected to the inlet and outlet ends of the U-shaped pipe located outside the geyser chamber. Installation and change of the displacement of the vertical position of the inlet of the nozzle relative to the top cover of the camera is performed using the node to move the pipe (SCP) without depressurization of the camera. The outlet pipeline is provided with a heat-shielding coating. The outlet pipe is connected to the inlet and outlet ends of the U-shaped pipe through valves that allow redistributing flows through the U-shaped pipe or bypassing it. A consistent pipeline is placed inside the well. After turning (pairing) in the bottom of the well, the U-shaped pipeline passes into the lower part of the geyser channel. The geyser channel ends with an exit section located above the surface of the earth. The outlet section of the canal is located in the center of the pool, stylized as a gryphon of a natural geyser and decorated with stones, geyserite and thermophilic plants. An explosive discharge of water and steam at the stage of geyser eruption is carried out from the exhaust pipe. Due to the fact that in a two-phase medium, which is a mixture of water and steam erupted by a geyser, the speed of sound is very small (30-40 m / s), the height of the water discharge even in the most powerful natural geysers is relatively small - a maximum of 20-25 m In this regard, to increase the height of the geyser ejection, the exhaust pipe is equipped with a supersonic nozzle with a smoothly expanding outlet section. One of the most optimal design options for this nozzle is a supersonic Laval nozzle for a two-phase mixture of water and steam. The pool is equipped with watertight walls and a drain pipe with a filter, and is connected to a wastewater system. This system provides the collection and removal of erupted water at a constant level in the geyser griffin. Near the outlet, a cold water pipeline with a valve is connected to the geyser channel. To reduce heat loss from the pipeline and the channel, their surfaces are covered with a layer of heat-shielding material. To prevent corrosion of metal pipes by groundwater, the geyser well is provided with a waterproof wall.

DETAILED DESCRIPTION OF THE INVENTION

The geyser chamber 1 (boiler), in which heating and boiling of water 2 is carried out, is placed in a small depression in the ground or on its surface. The heating of the chamber 1 is carried out by combustion products of natural fuel (gaseous, liquid or solid) or powerful electric heaters. Cold water is supplied to chamber 1 through a supply pipe 3 having a valve 4. Gaseous or liquid fuels mixed with air are burned using a burner 5. Combustion products cooled by contact with the heating surfaces of chamber 1 are released into the atmosphere through a chimney 6. Like standard water heaters with high steam pressure and steam boilers, chamber 1 is equipped with devices for controlling temperature (thermocouples and thermometers), steam pressure (pressure gauge 7) and water level (water gauge stack about 8). The exit of hot water, steam-water mixture and steam from the chamber 1 is carried out through the outlet pipe 9 located in it, connected to the section of the outlet pipe 10 located outside the chamber 1. Installation and changing the vertical offset of the inlet 11 of the pipe 9 relative to the top cover of the chamber 1 are carried out with using the nozzle moving unit (SCP) without depressurizing the camera. A description of possible design options for the soft starter is given below.

The outlet pipe 10 is provided with a heat-shielding coating. The pipeline 10 through the valve 13 is connected to the inlet and outlet ends 14 and 20 of the U-shaped pipe having valves 16 and 17, respectively. The outlet pipe 10 through the valve 16 is connected to the inlet end of the U-shaped pipe through the valve 16. The output pipe 10 is also connected to the bypass pipe 15 through the aforementioned valve 17. Said bypass pipe 15 is also connected to the output end 20 of the U-shaped pipe through the same valve 17. The U-shaped pipe is placed inside the well 18. After turning (pairing) 19 in the bottom of the well 18, the input end of the U-pipe 14 goes to the lower part of the output end 20. The output end 20 of the U-pipe the wire ends with an outlet pipe 32 of the geyser channel located above the ground with a shear nozzle 21. Thus, the bypass pipe 15 connects the portion of the pipe 10 (after the channel 13) with the upper part of the outlet pipe 32 near its outlet nozzle 21. The outlet pipe 32 is located in the center pool 24, stylized as a gryphon of a natural geyser and decorated with stones, geyserite and thermophilic plants, the complex of which is indicated in Fig. 1 by 22. Explosive discharge of water and steam 23 at the eruption stage the geyser is carried out from the outlet pipe 32. Due to the fact that in a two-phase medium, which is a mixture of water and steam, the geyser erupts, the speed of sound is very low (30-40 m / s), the height of the water discharge even in the most powerful natural geysers is relatively small - a maximum of 20-25 meters. In this regard, to increase the height of the geyser ejection, the exhaust pipe 32 is equipped with a supersonic nozzle 21 with a smoothly expanding output section. One of the most optimal design options for this nozzle is a supersonic Laval nozzle for a two-phase mixture of water and steam. The pool 24 is provided with watertight walls 25 and a branch pipe 26 having a filter 27 and is connected to a wastewater system. This system provides the collection and removal of erupted water at a constant level in the geyser griffin. Near the outlet pipe 32 to the outlet end 20 of the U-shaped pipe is connected to a cold water pipe 28 with a valve 29.

To reduce heat loss from the U-shaped pipeline, its surface is covered with a layer of heat-protective material 30.

To prevent corrosion of metal pipes by groundwater, the geyser well is provided with a waterproof wall 31.

The movement pattern of the end 11 of the outlet pipe 9

Changing the vertical position of the end 11 of the pipe 9 located inside the camera 1 can be carried out in various ways. In the process of testing the device and searching for the conditions under which the most intense eruption modes are provided, it is necessary to be able to vary the value of the vertical position (shift) of the inlet slice of the end of the nozzle that discharges hot water and steam from chamber 1 with respect to the top cover of chamber 1. The simplest and The following is a cheap technique for manufacturing a variation of this bias. An additional piece of pipe is attached to the flange of the outlet pipe 10 fastened to the chamber 1 lid, more or less hermetically (for example, by means of a threaded connection). If a small amount of displacement is required, use a short pipe, if you need to have a larger value, use a longer piece of pipe. Fixing the position is carried out using a lock nut or additional screws. The described simple system for varying the bias allows this operation to be carried out under the condition of depressurization of the camera 1. In the process of searching for optimal operating conditions of the IS, depressurization of the camera is undesirable, because reducing the pressure in the chamber requires cooling the water in it. This entails an unavoidable investment of time and greatly increases the cost of the search for optimal IG modes.

Somewhat more expensive to manufacture, but much more convenient for setting up an artificial geyser and fixing its parameters, providing the most powerful eruptions, is the use of a nozzle moving assembly (SCP), the circuit of which is shown in FIG. 2. The outlet pipe 9 is connected by a bellows 33 to the inlet section of the pipe 34 connected (for example, by a threaded or welding connection) to the flange of the inlet end of the pipe 10 fastened to the chamber cover 1. The screw 12 is provided with a high-temperature stuffing box seal (for example, made of Teflon powder), which makes it possible to operate the described device in the presence in the volume of the chamber 1 high temperature and high pressure, i.e. directly during the operation of an artificial geyser.

The lower end of the screw through a sliding sleeve 39 is connected to the end of the nozzle 9. By rotating the screw 12, the vertical position of the nozzle 9 is changed, i.e., the offset of the inlet slice 11 of the nozzle 9 relative to the lid of the chamber 1 is changed and, accordingly, the position of the slice 11 is changed relative to the water level in the chamber 1. In addition to the pipe 9 described above, the pipe 10 is connected by a pipe 35 having a valve 36 with an opening in the top cover of the chamber 1. If the outlet cut 11 of the pipe 9 is below the water level in the chamber 1, and if necessary it is filled e artificial steam piping system geyser, this operation is carried via line 35.

The pipe 10 is also connected through a valve 37 to a pipe 38, through which, if necessary, compressed air can be supplied to the piping system and chamber 1.

Implementation of the IG

1. IG start

Depending on the position of the valves of the system, the launch and operation of the IG can be carried out in various ways. When the IG starts, the stage of filling the system with cold water is, however, general. First, through the cold water supply pipelines 3 and 28 and the open valves 4, 29, 16 and 13, cold water is filled in the chamber 2, inlet and outlet ends 14 and 20 of the U-shaped pipe and the outlet pipe 10. After the filling process is completed, the cold water supply valves 4 and 29, as well as the main geyser valve (GAG) 13 are closed. The heating system of the chamber 2 is switched on, for example, by electric heaters or combustion products of natural fuel. In the latter case, gaseous or liquid fuel is supplied to the burner 5 having a standby torch or other system for stabilizing the combustion process. After the water temperature in chamber 2 and the vapor pressure in it have reached the set values, the artificial geyser is ready to start the development of the eruption process. In the initial position, the valves of the cold water supply pipes 29 and 4 are closed. The valve 13 and the valve 17 of the bypass pipe 15 are also closed. The valve 36 of the steam pipe 35 is closed. The valve 16 of the inlet end 14 of the U-shaped pipe is open. The end 11 of the pipe 9 is lowered below the water level in the chamber 1. Open the valve 13. Under pressure of steam in the chamber 1, water from it begins to move along sections 14 and 20 of the U-shaped pipeline.

At the beginning of this movement, the pressure in the chamber 1 drops insignificantly, which is associated with the small volume of the outlet pipe 10 and sections 14 and 20 of the U-shaped pipe compared to the volume of the chamber 1. At this initial stage of the geyser operation, primary cold water in the outlet pipe 10 and sections 14 and 20 of the U-shaped pipe begins to be replaced by hot water. Moving to the exit through the pipeline 10 and sections 14 and 20, hot water enters the conditions when the pressure is continuously reduced. There comes a moment of its boiling. The steam is replacing some of the water in the specified pipe and outlet end 20. The pressure drop ΔP, which ensures the movement of water and the steam-water mixture, is equal to

ΔP = P ₁ (T ₁ ) -P∞,

where P ₁ is the vapor pressure in the chamber 1;

T ₁ - water temperature in chamber 1;

P _∞ - atmospheric pressure;

The dynamics of water movement in the pipeline is described in the general case by the equation

where m ₁ = m ₁ (t) is the time-varying mass of water in the pipeline;

S is the cross-sectional area of the pipeline;

d is the diameter of the pipeline;

L is the total length of the pipeline sections filled with water;

dx / dt — velocity of the steam-water mixture;

d ² x / dt ² - acceleration of the movement of the steam-water mixture;

ξ is the coefficient of hydraulic resistance of the tract;

γ is the density of water;

g is the acceleration of gravity.

The main conclusion in the analysis of (2) is that as the volume (and mass) fraction of water in the pipelines of the geyser system decreases, the speed of movement of water and the entire two-phase mixture in it continuously increases.

After the last portions of cold water leave the geyser system, the main mode is the eruption of the geyser. According to the internal mechanism of the process and the observed visual and acoustic effects, this regimen is completely analogous to the eruption of natural geysers.

The eruption of the IG looks outwardly completely different compared to the work of a fountain, which almost silently ejects a stationary water stream, the diameter of which weakly expands with climb.

The eruption of an artificial geyser, on the contrary, is characterized by purely periodic, (in the terminology of volcanologists - “spasmodic”) powerful low-frequency emissions of the steam-water mixture. These emissions are accompanied by a characteristic roar caused by the presence in the sound spectrum of the explosive motion of a two-phase medium (water-vapor) of infrasonic acoustic frequencies. Steam in large clubs rises to a multimeter height. At the take-off stage, the water part of the two-phase mixture moves in the form of large portions unusual for free flight, reaching several centimeters in diameter. At the stage of falling, these portions of water are crushed and cool significantly.

Nevertheless, getting the audience under this hot rain is undesirable and they should be at a sufficient distance from the IS. The radius of the corresponding “safety circle” is close to the height of the water part of the geyser eruption.

The end of the first eruption

After the inlet 11 of the pipe 9 is significantly higher than the water level in the chamber 1, the metastable overheating of the water in the chamber 1 begins to decrease faster. The final stage of the eruption comes when more and more steam flows from the geyser channel. At the end of this stage, only steam expires from chamber 1. In natural geysers, after the end of the eruption, the influx of relatively cold groundwater increases in the free volume of the system, freed from the erupted water. This speeds up the eruption stop.

Similarly to this process, in order to accelerate the stop of the IG eruption and begin the next geyser cycle, valves 4 and 29 are opened and parts of the geyser system free from hot water begin to fill with cold water.

At the end of this process, valves 4, 29 and valve 13 are closed. Further, the process is repeated according to the scheme described above, with the difference that the initial temperature of the water in the chamber before starting a new portion of cold water is close to 100 ° C. Therefore, the duration of the normal geyser cycle in this mode is much shorter than the time taken to prepare the first eruption.

2. Eruption using inlet and outlet ends 14 and 20 of a U-shaped pipe

2.1. During the implementation of the geyser eruption in this mode, the valve 17 of the bypass pipe 15 is closed. Before the eruption, valve 16 is open, and OKG 13 is closed.

After the pressure and temperature in the chamber 2 has reached a predetermined level, the valve 13 is opened. Hot water rushes through the outlet pipe 10 and the inlet and outlet ends 14 and 20 of the U-shaped pipe. In the event that the inlet and outlet ends 14 and 20 were pre-filled with cold water, the latter first begins to be displaced in the form of an ordinary fountain from the nozzle 21. Then, the water in the indicated lines is mixed with hot water coming from the chamber 1, is heated and boils. Pipelines are filled with a two-phase water-steam mixture.

After the transition of this mixture into the so-called “Shell mode” water and steam emissions from the nozzle 21 acquire a low-frequency, “spasmodic” mode inherent in eruptions of natural geysers. The eruption is stopped similarly to the process described above in paragraph 1, “IG start”.

2.2. During the implementation of the geyser eruption in this mode, the valve 17 of the bypass pipe 15 is closed. Before the eruption, valves 16 and 13 are open. The valve 36 of the steam pipe 35 is also open. The end 9 of the pipe 11 is submerged below the initial water level in the chamber 1. As the temperature and pressure in the chamber 1 increase, the steam from it begins to move in pipelines 35 and 10 to the side of the input and output ends 14 and 20 of the U-shaped pipe. Partial condensation of steam in the moving water layers in contact with it leads to heating of the latter and a slowdown of the condensation process. Thus, more and more steam is collected in the pipeline 10 and in the section 14, the pressure of which increases with the pressure in the chamber 1. As the inlet end of the U-shaped pipe is filled with steam, water is displaced from its outlet end 20. After the first portions of steam will break from the input end 14 through the pairing 19 to the output end 20, a self-accelerating pressure drop in the chamber 1 will begin, accompanied by an increasing explosive process of eruption. The main part of the water and steam will move along the pipeline 9. This mode is provided by the position of the valve 36, the hydraulic resistance of which is made more significant compared with the hydraulic resistance of the pipe 9.

The eruption is stopped similarly to the processes described in paragraph 1 “Geyser Launch”.

2.3. The development of the eruption process in this mode is similar to that described in paragraph 2.2 above. The difference lies in the fact that at the stage of filling the chamber 1 and the inlet and outlet ends 14 and 20 of the U-shaped pipe with cold water through the open valve 37 through the pipe 38, compressed air is supplied to the pipe 10. The partial ingress of air into the gas volume of chamber 1 contributes to the stability of the eruption development process. The presence of an air piston separating the steam cushion in the chamber 1 and the initially cold water at the inlet end 14 of the U-shaped pipe almost completely stops the penetration of steam and its condensation in the inlet end 14 at the stage of temperature and pressure rise in the chamber 1. In this regard, the indicated increase the pressure in the chamber 1 will be accompanied by a synchronous decrease in the water level at the inlet end 14. After the breakthrough of the first portions of gas through the interface 19 to the outlet end 20, an eruption begins.

3. Eruption using only the outlet pipe 32 of the geyser channel.

At all stages of the process, including the supply of cold water to the chamber 1 and the eruption stage, the valve 17 of the bypass pipe 15 remains open and the valve 29 is closed. The valve 13 at the stage of heating the water and raising the pressure in the chamber 1 remains closed. After the water temperature and steam pressure in the chamber 1 has reached a predetermined level, open the valve 13.

Hot water from the chamber 1 through the outlet pipe 10 and the bypass pipe 15 rushes through the outlet pipe 32 to the nozzle 21. In connection with a drop in pressure, water begins to boil in the chamber 1 and pipelines 10 and 32.

The eruption has a pronounced explosive character, the intensity of which depends mainly on the degree and rate of opening of the valve 13 and the initial pressure values P ₀ and temperature T ₀ in the chamber 1, as well as on the initial position of the inlet section 11 of the pipe 9 relative to the water level in the chamber 1. The higher the pressure P ₀ and temperature T ₀ and the faster the valve 13 opens, the more intense the eruption process will be. The eruption will end spontaneously after the pressure and temperature in chamber 1 drop to values close to P = P _∞ = 1 atm and T ₀ = 100 ° C, respectively. However, the termination of the eruption can also be carried out by force by closing the valve 13. The duration of this process, as well as the duration of the opening of this valve at the beginning of the eruption, can be varied by the operator, which will ensure the visibility of the different modes of start, development and end of the eruption inherent in different natural geysers.

To fill chamber 2 with a new portion of cold water, the pressure in the chamber must be released during the eruption to a level lower than the water pressure in the supply pipe connected to the chamber 1 through valve 4.

4. Autonomous operation of an artificial geyser.

The use of the input and output ends 14 and 20, forming one vertical pipe of a U-shape, makes it possible to repeatedly carry out cyclic eruptions of an artificial geyser in an autonomous mode without operator intervention in its operation.

In this mode, the valve 13 is constantly open. The cold water inlet valve 4, assembled according to the "check valve" scheme, opens automatically if the pressure in the chamber 1 drops below the pressure of cold water in the supply line. With a corresponding increase in pressure in the chamber 1, the valve 4 closes.

The eruption of IG is as follows. The inlet and outlet ends 14 and 20 of the U-shaped pipe are filled with water from the pipe 28 having a “check valve” 29, operating similarly to the valve 4 described above. The position of the valve 36 of the steam pipe 35 and the outlet cut 11 of the pipe 9 is similar to that described in section 2.2 above. In the process of heating the chamber 1 and boiling water in it in the upper part of section 14, a steam bubble (“piston”) forms and grows. The continued increase in pressure in chamber 1 supports the increase in pressure drop in communicating vessels: in the inlet end 14 of the U-shaped pipeline, the upper part of which is filled with steam and the lower part with water, and in the outlet end 20 of the U-shaped pipe filled with water. After the vapor from section 14 breaks into section 20, part of the water from section 20 will be ejected with acceleration. The pressure in pipelines 10, 14 and chamber 1 will begin to drop, and the water in chamber 1 will be metastable overheated. Under these conditions, accelerating spontaneous boiling of superheated water begins in the chamber 1, in the pipeline 10 and sections 14 and 14, accompanied by "spasmodic" emissions of the two-phase mixture from the nozzle 21.

The eruption spontaneously ceases due to a drop in temperature in chamber 1, due to the action of the following two factors:

1) accompanied by a drop in pressure in chamber 1, the transition of the thermal (potential) energy of superheated water in chamber 1 into the kinetic energy of a two-phase mixture ejected from nozzle 21;

2) the introduction into the chamber 1 of new portions of cold water through the valve 4 through the pipe 3, starting after the pressure in the chamber 1 becomes less than the pressure in the supply line of cold water. After filling the chamber 1 to the required level, the cold water valve 4 closes.
