Description

The invention relates to energy, and in particular to steam generators, and since the generator has a small mass, it can be used as a source of steam for a trackless vehicle engine.

A steam generator is known comprising a body heated externally and a central body coaxially mounted therein, forming a conical annular channel connected to the inner surface of the housing and connected by a narrowed portion to a source of heating medium, the central body being rotatably mounted around the axis 1.

A disadvantage of the device is that with a relatively small volume of generated steam, the dimensions of the installation are large.

A steam generator is known, comprising a steam chamber with a water distribution device having inlet and outlet sections, the last of which is located a heating nozzle in the form of a heat-resistant casing filled with heat-accumulating material, with upper and lower rows of heaters placed in its volume, and in the nozzle between by the heaters of the upper row, steam exhaust channels are made in communication with the steam chamber. Heat storage material is a fusible material (mainly lead, tin or an alloy thereof) 2.

The disadvantage of this steam generator is its low reliability due to the possibility of deformation and destruction of the casing due to different expansion coefficients when heating lead and steel. In addition, the use of a lead bath increases the mass of the steam generator.

The aim of the invention is to increase reliability and reduce the weight of the steam generator.

This goal is achieved in that the steam chamber is detachable in the form of a cylinder with hemispherical bottoms, the heating nozzle is made in the form of separate annular sections, each of which has its own casing made of heat-conducting stainless material with heat-accumulating fillers in the form of ceramic elements, having the shape of parallelepipeds with holes in which the heaters are located, moreover, the water distribution device is made in the form of a tube muffled from one end mounted on the axis of the steam the first chamber with the possibility of rotation and providing a constant speed of rotation, and its atomizers - in the form of jet nozzles.

connected to a tube in the region of said sections.

Section casings are made mainly of silver.

In FIG. 1 shows a general view of a steam generator; in FIG. 2 - node I in FIG. 1; in FIG. 3 is a section AA in FIG. 1; in FIG. 4 - node II in FIG. 3.

In the housing of the 1-steam generator, composed of two halves connected by bolts, a steam chamber is made inside, having the shape of a cylinder with hemispherical bottoms. For example, heating nozzles in the form of separate annular sections 2 are fixed on brackets on the inner side cylindrical surface of the steam chamber. For each section, there are jet nozzles 3 with sprayers 4, in which a number of small-diameter holes are made, which allow crushing water into small droplets.

The nozzles 3 are mounted on the tube 5, which is plugged at one end and mounted on the axis of the steam chamber with the possibility

rotation at a constant speed from an autonomous drive. For this, the muffled end of the tube 5 is installed in the sleeve 6, pressed into the housing 1, and at the second end of the tube 5 a drum 7 is secured

0 with sealing rings 8 interacting with the machined surface of the cap nut 9 screwed into the second hemispherical bottom of the housing 1. This assembly is the second support of the tube 5. On

5 at the same end, on the threaded part of the tube 5, nuts 10 are fixed to the gear 10, which interacts with an autonomous drive (not shown), which informs the tube 5 at a constant angular velocity. Rotational speed

0 gear 10 should be such that the sprayer 4 sprayed part of section 2 with such a speed that its other part, located in front of the sprayed, would be heated to such a temperature, at

5 of which the droplets falling on it instantly evaporated.

Water in the rotating tube 5 comes under pressure, for example, from a reservoir closed on all sides (not shown), into

0 of which a constant overpressure is created with the help of the pump, while water from the reservoir into the pipe 5 enters through a sealing device containing a pipe fixed to the threaded part of pipes 5 "and 5 with nuts, a drum 11 with o-rings 12, a cap nut 13. with the treated inner part of which the rings 12 interact, and the bell 14. 8 the last screwed cap nut 13. To the bell 14 is attached

a pipe 15 in communication with a reservoir supplying water to a steam generator.

The heating nozzles are made in the form of separate annular sections 2, which have (their heaters 16, heat-accumulating fillers 17 in the form of ceramic elements made in the form of parallelepipeds with holes in which the heaters are located 16. The extreme fillers 17 have a groove into which the part of the heater is bent 16. Outside the cushions, the casing 18 is made of a thin sheet of silver or other material that is not oxidized when water enters it and conducts heat well. The casing 18 prevents water from entering the filling spruce 17 and this prevents them from cracking. Fillers 17 with heaters 16 and casing 18 make up the annular section 2, while the section ring is detachable, one part of it is fixed in one half of the housing 1 and the other in the other The wires from the sections through a rheostat (not shown) are connected to a source of electric current (not shown).

To drain condensate from the steam meter of the housing 1, a valve 19 is provided in it.

Between the tube 5 and the reservoir in which the overpressure is generated, a valve 20 is installed to control the flow of water from the reservoir to the tube 5.

The steam from the housing 1 is discharged through a pipe 21, the outlet of which is blocked by the rotating valve 22, with the help of this valve the steam is supplied in portions to the consumer.

Outside, the housing 1 is closed by a thermal insulator 23 enclosed in a casing 34.

The steam generator operates as follows.

In order for the steam generator to work for a long time, it is necessary to exclude scale deposits on the annular sections. Therefore, well-treated rainwater must be used. Most preferred is a closed cycle in which the steam used is converted to water, which, after cleaning from oil and impurities

it is again pumped into the tank supplying the steam generator with water.

Before starting work, you should remove condensate from the steam chamber of housing 1 by opening valve 19, and then it must be closed. Then, turn the heaters 16 into the circuit of the electric current source and heat the annular sections 2, as well as the cavity of the steam chamber in the housing 1. Then, the rotation mechanism of the pipe 5 must be turned on and the pipe 5 connected to the tank 5 with the reservoir where water is compressed.

Water entering the tube 5, through nozzles 3 and nozzles 4, drops in small drops onto the heated sections 2 and comes into contact with them, instantly evaporates, turns into steam, which, in contact with other heated parts of section 2, is converted into dry steam. Peer accumulated in the overpressure steam chamber through line 21 and through spool 22 is directed to the consumer. In order to stop the production of steam, turn off the water supply valve 20 and disconnect the heaters 16 from the current source. Then turn off the rotation mechanism of the tube 5. If a smaller amount of steam is to be supplied to the consumer, then the valve 20 reduces the water supply to the tube 5 and reduces the force current to the heater m 16.

Since the tube 5 with nozzles 3 and nozzles 4 constantly rotates, the temperature of the sprayed part of each section, generating steam, decreases, and then, when there is no water coming in, this part of the section quickly heats up to the required temperature. For this reason alone, it is necessary to have a silver casing 18 having the property of being rapidly heated.

The small weight of the compact steam generator allows it to be used as a source of steam for an engine of a trackless vehicle.

The use of steam for the engine of a trackless vehicle will drastically reduce the release of substances harmful to mankind into the environment.
