The utility model relates to an electrolysis apparatus for producing Brown gas, which will find application in energy.

BACKGROUND OF THE INVENTION

It is known in the art an electrolysis apparatus for producing Brown gas from distilled water consisting of a closed vessel with an electrolytic cell immersed therein. The electrolysis cell is made up of electrolysis plates clamped in a package. The electrolysis cell package is secured to the vessel walls. All electrolytic cell plates have remote conductive edges connected via DC busbars to a constant voltage source. The closed vessel is provided with a pipeline for supplying distilled water. At the upper end, the vessel is provided with a pipeline for the removal of Brown gas.

The known electrolysis apparatus for producing Brown gas works with distilled water and is not suitable for use with seawater or contaminated water, which in practice limits its functionality.

The technical nature of the utility model

The object of the utility model is to provide an electrolysis apparatus for producing Brown gas, which can effectively handle seawater and other types of contaminated water, and which allows the extraction of industrially applicable materials from the water used.

The created electrolysis apparatus for producing Brown gas consists of a vessel with an electrolytic cell immersed in it, composed of electrolysis plates, clamped in a package, secured to the walls of the vessel. The electrolysis plates have remote conductive ends connected by DC voltage source busbars. The vessel is provided with a water supply pipe, and at the upper end it is provided with a pipeline to discharge Brown gas. According to the utility model, the vessel is made up of a bath and a lid. At the top, the electrolysis cell is enclosed by a sludge collection frame. Under the electrolysis cell is installed a nozzle feeder connected to the seawater supply pipe. In the lower part of the tub, a water suction line is installed under the electrolysis cell to remove the collected sludge from the sludge collection frame. The suction line through the circulation pump and the separator filter is connected to a sludge dryer. At the top of the tub is a cone-shaped lid at the top and a cylindrical shape at the bottom. A fire barrier is installed in the upper part of the lid, in which a backward-facing bubbling tube is mounted, one end of which is connected to the gas space under the cover and the other end is immersed in water in the barrier.

- with its help, in addition to Brown gas, industrially applicable materials are extracted from the water, which are mainly raw materials for the metallurgical industry;

- the product obtained from the electrolysis apparatus is environmentally friendly and furthermore distilled water is produced upon combustion.

Explanation of the annexed figures

This utility model is illustrated with the accompanying figures, where:

Figure 1 is a schematic diagram of a closed type electrolysis apparatus;

2 is a diagram illustrating the principle of operation of the electrolysis apparatus of FIG. 1; and Figure 3 is an open type electrolysis apparatus.

Exemplary implementation of the utility model

The electrolysis apparatus is developed in two variants - open and closed type.

Closed-type electrolysis apparatus3

2214 υι is a vessel made up of bath 1 and a lid 17. Bath 1 is filled with seawater fed through an electric valve 22. The electrolysis apparatus is mounted on supports 2 - figure 1. An electrolysis cell 3 is assembled inside bath 1. of multiple electrolysis plates 4, clamped together by plastic pins 5 with plastic nuts 6. Plastic pins 5 are mounted in openings formed in the electrolysis plates 4, and spacer bushings are mounted on the pins 5 and between the electrolysis plates 4, with the help of which supported op separated distance between electrolysis plates 4 - in this case the distance between electrolysis plates 4 is about 3 pieces. All the electrolysis plates 4 of the electrolysis cell 3 have remote conductive ends connected by means of current buses "plus" 7 and "minus" 8 with a constant voltage source.

Under the electrolysis cell 3 is installed a nozzle feeder 9. The nozzle feeder 9 is connected to the water supply pipe 10.

At its upper end, the electrolysis cell 3 is enclosed by a sludge collection frame 12. The nozzle feeder 9 "blows" the sludge from the bottom up, while the water flow helps to separate the gas bladders from the electrolysis plates 4 and facilitates their opening to the sludge collector 12. By assisting the separation of gas bubbles from the electrolysis plates 4, the upstream flow of water from the bottom up also improves the efficiency of the electrolysis process.

In the bath 1, near the nozzle water dispenser 9, a water suction line 11 is installed, which serves to discharge the permanently collected sludge through the collecting frame 12, which covers the entire electrolysis cell 3. The inner edge of the frame 12 is almost at the water level. , and the outer edge is raised higher to prevent sludge from leaving the frame 12.

By means of a circulation pump 13, the collected sludge is sent to a filter separator 14, from where the sludge is discharged through a pipeline to a sludge dryer 15, FIG. 2.

The purified water from the filter separator 14 is returned to the electrolysis apparatus through a second circulation pump 16 through the water supply pipe 10. Typically, the returned water flows from the underside of cell 3 through the nozzle feeder 9 and "purges" cell 3 from random sediment particles and sends them to the upper side for removal through the frame 12.

The entire tub 1 is covered by a cone-shaped lid 17 at the top and cylindrical at the bottom. In the lower cylindrical part of the lid 17, special edges are formed with seals and a locking mechanism 18, by means of which a hermetic connection between the bath 1 and the lid 17 is provided.

Inside the lid 17, conductive plates (not shown in the figure) are used to control the water level. Instead of conductive plates, a non-contact ultrasonic water level control can be installed for the same purpose.

Above the cone-shaped portion of the hood 17 is a fire barrier 19 in which a backward facing i-shaped bubbler tube 20 is mounted, one end of which is connected to the space enclosed by the hub 17 and the other end of the i-shaped bubbler tube 20 is immersed in the water in the firebox 19. Over the firebox 19 a pipeline 21 is installed to discharge the Brown gas.

Figure 3 illustrates a variant embodiment of an open-type electrolysis apparatus intended for use in the sea submerged in seawater, the pressure in the apparatus dependent on the depth of immersion. The pressure in the apparatus must not exceed 3 gL or a depth of 30 t.

Open-type electrolysis apparatus is different from closed-type electrolysis apparatus in that:

- the lid 17 already acts as a bell, there are no seals on its underside, the lid 17 being placed directly on the bottom of the bath 1, which is always completely submerged in the water. The electrolysis cover 17 is narrower and covers the electrolysis cell 3 together with the sludge collecting frame 12 and the nozzle feeder 9;

- the entire electrolysis apparatus is covered by a special Faraday mesh cell 22, which cell 22 operates under pulse voltage in synchrony with the pulses supplied to the electrolysis cell 3.

2214 υι

The open and closed type electrolysis apparatus are of similar construction, with the difference in the size of the hood 17 and seals and locks are not used in the open type electrolysis apparatus.

Principle of operation of the utility model

The electrolysis cell 3 is powered by a power supply unit (not shown in the diagram) with output parameters - voltage 12-13 V and current up to 300 amps. In order to avoid heavy transformer structures and to facilitate regulation of current and voltage, it is envisaged that the power supply should be pulsed. The supply current is straight but pulsed from 0 to 12-13 V, with the generator capable of adjusting the frequency of the current from 0 to 45 ΜΗζ with rectangular pulses, with the possibility of adjusting the width of the pulse and the distance between the pulses.

The process of Brown gas production is an electrolysis process controlled by a pulse generator that controls the shape, frequency, width, pulse distance and regulates the current. In this way, the amount of Brown gas produced is regulated based on the estimated power extracted from the electrolysis cell 3, which is also dependent on the conductivity and the quality of the seawater.

A characteristic feature of the process in the apparatus designed to obtain Brown gas from seawater is that it is accompanied by the release of a large amount of sediment in a relatively short time. This requires their timely and rapid removal to prevent deterioration of the electrolysis process. Since the separation of sludge is associated with a change in electrical conductivity, the state of electrical conductivity is continuously monitored and corrected with the help of alkaline substances, most commonly potassium.

At the start of the electrolysis, sedimentation immediately begins. For this purpose, a circulating pump 13 is provided which sucks the separated sludge from the sludge frame 12, pumps the sludge emulsion into the filter separator 14 and returns the purified water back to the bath 1, but from the underside of the electrolysis cell 3 so that the incoming water to "purge" the space between the electrolysis plates 4. The natural movement of sediment particles with such "purging" is upward, under the influence of gas bubbles rising to the surface, where the particles accumulate as caffeine so that the "purging" promotes the natural circulation of the sediment particles.

The Brown gas produced, collected in the dome of the hood 17, enters the fire barrier 19 through an opening, where it bubbles, the gas is separated from the water and through the pipeline 21 is put to use.

A characteristic feature of an open-type electrolysis apparatus is that it is not sealed but covered by a Faraday-type mesh cell. The isolation of the gas produced from the atmosphere and its removal is carried out by the hood 17, which is located directly on the bottom of the bath 1, which is always completely submerged in the water.
