Description

There is a known method of converting thermal energy into mechanical energy, using two steam engines, one of which operates with steam produced from a scoop, in which 1% alkaline solution (for example, caustic soda solution) and gives off steam filled with alkaline solution too, but with less concentration, absorber, serving as a heat source for generating steam for the second engine. In the proposed method, a solution of such a concentration is used in the absorber, at which a sufficiently high temperature is maintained in the absorber to transfer heat from it to the secondary boiler, and absorption takes place under pressure below atmospheric.

The proposed method can be modified by using several closed cycles of operation with the sequential inclusion of absorbers and evaporators and the use of solutions of different concentrations in them;

In FIG. 1. 2 explain the proposed method; FIG. 3-modified method.

In the primary boiler 1 (Fig. 1) and in the absorber 2 there is an auxiliary liquid (e.g., caustic potash solution) of high concentration, and in the secondary boiler the evaporator 3 there is water. Obtained in the evaporator 1, due to the action of the furnace 4, the steam is sent to the steam turbine 6 and after the work is done, it passes through the pipe 7 to the spray device 8. The auxiliary fluid from the absorber 2 is pumped by the pump 9 to the primary boiler and back through the pump. the preheater 10, which is under pressure in its part, is higher than the pressure in the boiler, and ends with a reducing valve 13 in its outgoing part. At the same time, the pump 14 pumps fluid from the absorber 2 through the heating coil 15 and the pipe 16 into the spraying device 17, from which this gKndkoe in the sprayed form comes to meet the pair, also scattered in the device 8, and absorbs this pair. The heat transferred through the coil 15 to the water of the secondary boiler 3 generates a relatively high pressure steam. This condensed steam operates in turbine 18 and is directed through conduit 19 to the condenser 20. In FIG. 2 shows a diagram of an apparatus for generating pressurized steam by letting in steam into a liquid. In the primary boiler 2i and in the absorber 22, there is an auxiliary liquid, jianpHiiep, caustic soda. Obtained in the boiler 21 under the action of the furnace 23, the steam is directed through the pipeline 24 to the turbine and the nocvie of its use flows through the pipeline 2e into the mixing device 26, in which it is connected to the auxiliary liquid. The heat liberated in this case forms steam in the secondary boiler of the evaporator 27, which can be directed through the pipeline 28 to the place of consumption. The pump 29 serves to circulate the auxiliary fluid between the primary boiler 21 and absorb the body 22. The pump drives the auxiliary pressure under pressure higher than the pressure in the boiler 21 through the counter heater 30. In the pressure reducing valve 1, the pressure drops to the pressure of the boiler 21, and under this pressure, the auxiliary fluid enters through the pipe 32, the heater 30 and the pipe 33 into the reducing valve 34 from the x-one, after a corresponding pressure drop, returns back to the absorber 22.

Shown in FIG. 3 illustrates a method for converting thermal energy into mechanical energy, in which several consecutive closed cycles of operation with sequential switching on of absorber-evaporators are applied. The diagram shows; two elements of the installation for transforming world tealotn with pipelines connecting these elements; Each of the elements consists of an absorber and an evaporator; element 41 is from absorber 43 and isparum 44, and element 42 is from absorber 45 and evaporator 46. The auxiliary liquid inside the absorber 43 injects steam through line 47. The heat released by the mix produces 44 vapor at a relatively high pressure, evacuated by pipelines 48 to the supervisor and pz next flowing through pipeline 49 to the absorber 45. 0-; the heat of displacement in the latter forms in the evaporator 46 pairs that can be discharged through pipeline 50 to the place of consumption 1 and. The main circuit of the complementary train comes from the absorbers to the evaporator and back to the absorbers in the next order. The auxiliary liquid (eg, sodium hydroxide) flows from the absorber 43 through pipe 51 through the pump pump 52 to the evaporator 46 and then through pipe 53 to the evaporator 44. From here it flows through pipe 54 and through the reduction valve 55 to the absorber 45, and the latter through the pipe 56, the absorber 43 so as to return from it through the pipe 56 to the absorber 43. On its way, the auxiliary liquid undergoes a concentration increase in the evaporators 46 and 44, and a decrease in the concentration 45 and 43, so that constant concentrations are established in individual vessels. In addition to the main circulation, here are envisaged additional circulation systems for the purpose of improving heat transfer. Circulation in the absorber system 43 is supported by a pump 58, at which time the former takes the auxiliary liquid from the absorber 43. through the pipe 57, and returns it through the pipe 59. The corresponding circulation system of the absorber 45 consists of pipe 60, pump 61 and pipe 62.
