The invention relates to a compressor industry and can be used in compressors that compress a gas by transferring it through a hydrated state.

The purpose of the invention is to improve the economy.

The drawing shows a thermocompressor.

The thermocompressor comprises a housing 1 with coaxial chambers to form 2 gas hydrate slurries and 3 gas hydrates to melt, between which filter A is installed, having the shape of a truncated cone, facing a large base 5 to gas slurry 2, located along the filter axis 4 screw 6, cup 7, connected to the larger base 5 of filter 4 and chamber 2 of slurry formation and provided with a last filter space 8 on the side and filter 4 with hollow radial partitions 9 with perforated walls 10, cumulative 11 and flushing 12 chambers and sump 13, associated respectively with filter spacer 8, filter 4 and melting chamber 3, low pressure gas pipelines 14-20 into the slurry chamber 2 and removal of high pressure gas from chamber 3 melting, supplying the suspension to the filtering unit 8, supplying the source water, supplying desalinated water to the consumer, discharging the spent brine, connecting the cavity of the partitions 9 to the sump 13.

The thermocompressor additionally contains a suspension separation chamber 21, an additional filter 22, i.e., the initial water is connected to supply transformer tap 16, and tap 19 to discharge spent brine to K 26. Closure plug 25 regulates the pressure of pressing salt crystals. Offsetting the initial brine from C fed from K 21 to cup 7 lowers the brine concentration in C, thereby facilitating the washing of gas hydrates from brine 1 h. Clause 1 Il

a truncated cone shape, a conical screw 23 located therein, a cylinder 24 closed at one end by a spring-loaded stopper 25, a discharge chamber 26 and a recirculation pipe 27 connecting the storage chamber 11 to the slurry chamber 2, the slurry separation chamber 21 communicating with the chamber 2 the formation of a suspension in its lower part, to the chamber 21 of the bottom is connected with a large base 28 an additional filter 22, less

the base 29 of which is connected to the open end of the cylinder 24, the discharge chamber 26 communicates with the additional filter 22, the source water supply pipeline 17 is connected to the suspension supply pipeline 16, and the spent brine removal pipeline 19 to the discharge chamber 26.

The recirculation pipe 27 is provided with a pump 30. In the chambers of the formation of 2 slurries and melting 3 hydrates, and in the pipe 20, heat exchangers 31-33 are installed. Wash chamber 12 is connected to pipe 20 by pipe 34.

Thermocompressor works as follows.

The mineralized water enters the thermocompressor through conduit 17 into the cup 7 of the housing 1, passes through the filter spacer 8, enters the collection chamber 11, from where the conduit 27 flows into the chamber 2 to form a suspension of gas hydrates. and contacts it with a low pressure gas to be compressed, which is introduced into the submerged

saline water the lower part of the chamber 2 through the pipeline 14 through the nozzle. The temperature of the saline water in chamber 2 due to cooling in the heat exchanger 31 is cooled by dropping water with water below the hydrate formation boundary at the operating pressure in chamber 2. Therefore, when bubbling low pressure gas through saline water, gas hydrates form and grow.

Since fresh water is a part of gas hydrates, the concentration of saline water increases up to the formation of saturated brine. With the further formation of hydrates from the saturated brine, salt crystals begin to precipitate, which, together with the gas hydrates and the saturated brine, form a suspension with a solid phase. The suspension enters chamber 21

20 from the zone of the filter 4, the subsequent gradual compaction of the compacted hydrated mass and the creation of a hydraulic valve preventing the ingress of gas into the washing zone

separation of the suspension, in which the separation occurs due to separation of 25 hydrates. The hydrate piston destroys the densities of the two solid phases into, and the hydrates rinsed into the heated solution at two streams (the density of gas hydrates is 900–1080 kg / m, depending on the nature of the gas, the density of saline brines is 1100– 1200 kg / m, the density of salt crystals is 1600-2100 kg / mz).

The gas hydrates, together with the saturated brine through the pipeline 16, under the pressure created by the pump 30, or the heat exchanger 32 slurry, are melted in the chamber 3 with the release of high pressure gas and fresh water. 30 The heat required to melt the hydrates is supplied by the hot water circulating in the heat exchanger 32.

Another part of the fresh water through the pipeline 18 is removed from the tern at the outlet of the filter spacer 8, the porous scooter compressor 50 begins to form, the gas hydrate piston moving to the screw 6, the passage through the zone with baffles 9 into which under pressure 100–150 kPa exceeding the pressure behind the filtering spacer 8, fresh wash water is supplied through pipelines 20 and 34. The latter is evenly distributed through the perforated walls 10 of the surplus. The salt crystals are deposited 21 times. The slurry suspensions are screwed into the screw coil 23 at the base and, moving 55, are pressed, as a result of crystalline voids, the saturated brine is passed through a bottom filter 22 into the chamber 26, swarm it through the pipeline 19

The rod 9 in the mass of gas hydrates displaces the brine from intercrystalline voids and washes the gas hydrates from residual brine and soils.

The formed piston of washed gas hydrates, having about 40–50% (by volume) of fresh water in intercrystalline voids, is captured by the first turn of the screw 6 at the base 5 of the filter 4 and, moving up, is pressed to compress pressure of the gas, resulting in formed hydrate piston through the filter 4 into the chamber 12 presses - with the bulk of the water, which through the pipeline 34 is recycled to the washing in the partition 9. With further movement of the hydrates after

A slurry, circulating in the melting chamber, composed of water, dissolved gas and bubbles of insoluble gas in it, enters the sump 13, where it partially dissolves non-dissolved gas, and high pressure gas

through line 20 through heat exchanger 33, where it is cooled by discharged brine, in order to prevent the hydrates from melting during the washing and pressing process, is fed to.

perforated walls of the 10 partitions 9. Another part of the fresh water through the pipeline 18 is removed from the thermocompressor 50 to the consumer,

The salt crystals settle in the suspension separation chamber 21 onto the first turn of the screw 23 at the base 28, are captured by it and, moving down, 55 are pressed, with the result that saturated brine is squeezed out of the intercrystalline voids through the additional filter 22 into the chamber 26, from which pipeline 19 through tep

the heat exchanger 33 is discharged from the thermocompressor. The pressed salt crystals through the smaller base 29 of the filter 22 enter the output cylinder 24, in which a hydraulic shutter is created, preventing the brine from flowing out through the output cylinder 24, interacting with a shut-off cone that destroys the pressed conglomerates of salt crystals, and is output to the consumer. A spring loaded stop plug 25 controls the pressure of the pressing of salt crystals. In addition, the spring presses the closure plug 25 to the output cylinder 24 during the start-up period of the thermocompressor, when a sufficient number of salt crystals have not yet formed, thereby blocking the output of the brine thermocompressor through the output cylinder 24.

The mixing of the initial brine with the suspension supplied from chamber 21 to cup 7 lowers the concentration of the brine in the suspension (gas hydrates - brine), thereby facilitating the washing of gas hydrates from the brine.
