Description

The invention relates to a power system, and in particular to the field of generating hot steam, and can be used for industrial or individual needs, including for the formation of heating systems.

There is a known method of generating steam, in which steam is produced by electrically acting on the water filling the boiler, through electrodes installed in water, followed by its additional heating (see, for example, RF patent No. 2225569, IPC F 22 V 1/30 “Steam generator”, published March 10, 2004, in B.I. No. 7).

The design of the steam generators made by the known method is relatively simple, however, they contain two systems of electrodes. Moreover, if certain proportions of the structure are not observed, the operation of such steam generators is disrupted, which reduces their reliability.

Closer adopted for the prototype is a method of generating steam, in which the boiler is filled with water to the required level and produce an electrical effect on the water through electrodes placed in water (see, for example, RF patent No. 2225569, IPC F 22 V 1/30 "Steam Generator", published on March 10, 2004, in B.I. No. 7).

The design of the steam generators according to the known method of generating steam contains a boiler with two compartments and a complex and cumbersome system of valves and pipes. In addition, to obtain steam requires a long period of time between the start of the system and the moment of output.

The objective of the invention is the creation of simple in design, reliable and small-sized steam generators, combining in one steam generator two operations - heating the coolant and forcing it into the heating system and increasing productivity when receiving steam. In this case, a reduction in the cost of the units necessary for generating steam is achieved.

This problem is solved by the fact that in the known method of generating steam, in which the boiler is filled with water to the required level and produce an electrical effect on the water through electrodes placed in water, according to the invention, the electrical effect on the water is carried out by high voltage pulses, and water generated during electrical exposure jets transform the dispersed structure by passing water jets through a divider, which is a system that prevents the free passage of water uy.

In a known steam generator comprising a boiler filled with water, nozzles for water inlet and steam outlet, electrodes placed in the water, and the power supply system according to the invention, a divider is installed between the steam outlet pipe and the water surface, consisting of plates adjacent to each other, windows separated by partitions are carved in the plates, and the plates alternate so that the windows of the plates are partially overlapped by the partitions of adjacent plates.

The process of generating steam, in which electrical impulses are applied to water by high voltage pulses, and the water jets formed during electrical action are converted into a dispersed structure by passing water jets through a divider, which is a system that prevents the free passage of water jets, which can significantly reduce the overall dimensions of the steam generator, reduce the cost of installations and the cost of a unit of production, as well as increase the productivity of the unit and accelerate the process of steam generation.

In the device of the steam generator, the presence of a divider between the steam outlet and the water surface, consisting of plates adjacent to each other with windows cut in them, separated by partitions and installed so that the plate windows are partially overlapped by the partitions of adjacent plates, allows you to quickly convert the energy of an electrical pulse into energy couple. This design can significantly reduce the overall dimensions of the steam generator, and the process of steam formation occurs almost instantly from the beginning of the machine.

The invention is illustrated by 4 figures.

Figure 1 presents a General view of a pulsed steam generator.

Figure 2, 3 shows the design of the plates of which the divider is made.

Figure 4 shows the design of the divider.

Pulse steam generator is arranged as follows.

The boiler 1 is made in the form of a tank having a plan in the form of a rectangle. A support frame 2 (an open box) is installed at the bottom of the boiler, the outer perimeter of which is equal to the inside perimeter of the boiler 1. A support gasket 3 made of heat-resistant rubber, such as polyurethane, is installed along the upper edge of the frame 2. On the gasket 3, a divider 4 is installed, which is a system that prevents the free passage of water jets. A sealing gasket 5, also made of heat-resistant rubber, is installed along the edge of the upper perimeter of the divider. A thrust frame 6 is installed on the gasket 5, made similarly to frame 2, but having a slightly lower height. Around the perimeter of the upper edge of the tank 1 is a sealing gasket 7, also made of heat-resistant rubber. The tank is covered with a lid 8 so that the lid fits snugly against the thrust frame 6 and the gasket 7. The lid is equipped with an outlet pipe 9. The lid 8 and the tank 1 have external legs 10 and 11, respectively, whose planes are opposite each other. Coaxial holes were made in the paws into which tightening bolts (not shown) were inserted. The lower part of the tank 1, in which the support frame 2 is located, is filled with water 12, the level of which is slightly lower than the upper edge of the support frame. The lower part of the tank 1 and the supporting frame 2, located below the water level 12, have a through hole (not indicated), which is connected by a hose 13 to the filling tank 14. The tank 14 is filled with water, the level of which is equal to the water level in the tank 1. The filling tank has a float water level regulator 15 in the tank. The hose 13 is equipped with an electrically controlled shut-off valve 16. The latter is electrically connected to the power supply and electric control system 17, which also includes a high-voltage pulse generator. Inside the tank 1, below the water level 12, electrodes 18 are inserted, separated by a small gap (not indicated). The electrodes are electrically connected to a pulse generator located in the system 17.

In turn, the divider 4 consists of plates 19 and 19 '(Fig.2, 3). Windows 20 are cut in the plates, separated by partitions 21. The window, located at one of the edges of the plates, has no partitions. The plate thickness is 0.1 mm. The plates at the edges are provided with through round holes 22. The plate 19 ′ in FIG. 3 differs from the plate 19 shown in FIG. 2 only in that the plane of the first is rotated 180 degrees relative to the second by a longitudinal axis. Windows 20 and partitions 21 are selected so that if the plate 19 in figure 2 and the plate 19 'in figure 3 are connected by planes with each other so that the holes 22 coincide, then the windows 20 of the plates will partially overlap with partitions 21. In this case, the partitions of the corresponding plates will be located in the middle of the windows.

In the divider (Fig. 4), the plates 19 in Figs. 2 and 19 'in Fig. 3 alternate and are joined together by rivets (not marked) passing through the openings 22. In this case, a structure is formed that prevents the free passage of water jets formed when electrical effects on water. The divider with the help of the plates dissects the jets, makes the dissected water jets move in a zigzag pattern between the plates and converts the water into a finely divided mass.

Pulse steam generator operates as follows. When applying high-voltage pulses to the electrodes 18 in water 12, an electro-hydraulic shock occurs, which has high energy. This blow is accompanied by the formation of powerful water jets that rush up. Passing through the divider 4, the water mass of the jets is dissected into small drops, which, passing at high speed, rub against the walls of the plates 19 and 19 'and heat up to the state of steam. Steam at the outlet pipe 9 enters the place of its disposal. Until a high-voltage pulse is supplied to the electrically controlled valve 16, a command is issued to shut it off, which prevents the shock wave from passing into the filling tank 14. After the pulse has passed, the valve 14 opens and water flows by gravity into the tank 1, replenishing part of the water expended in the formation of steam. Thus, the same volume of water is stored in the tank 1. The water level in the reservoir tank 14 is maintained by the float regulator 15.

The advantages of the proposed method for producing steam are:

1. The simplicity of the design.

2. High reliability.

3. Small overall dimensions and weight.

4. High performance.

5. Almost instantaneous vapor formation from the beginning of the first pulse.

6. Regulation of steam production over a wide range.

Due to these advantages, the proposed pulsed steam generator can be widely used in various industries.
