The invention relates to devices for gas purification from the solid phase, in particular for wet gas cleaning in sugar beet production.

The purpose of the invention is to expand the functionality of the device due to the effective simultaneous purification of gas and water.

The drawing shows the proposed device, a cross-section.

The device for wet gas cleaning contains a hydrocyclone 1, an ejector 2, which is mounted in the inlet pipe 3 of a hydrocyclone t. A separator 4 is placed over the hydrocyclone 1. The gas is supplied to the ejector 2 through the nozzle 5 and nozzle 6 located in the center of the ejector 2 axially. The liquid is supplied to the ejector 2 through the nozzle 7 and the nozzle 8. The reagent solution (coagulum, flocculant) enters the ejector 2 through the nozzle 9. For feeding the mixture of water, gas and reagent solution from the hydrocyclone 1 to the separator 4 an outlet pipe 10 is used, which is attached to the conical bottom 11 of the separator 4. A bath 12 is formed on the bottom 11, which is designed to collect water and coarse particles enlarged as a result of coagula. A reflective umbrella 13 is installed above the pipe 10, and bath 12, consisting of enlarged particles, - a conduit 14, between the inlet in which and the bottom of the bath 12 a slot 15 is formed. In the separator 4, mount over the bath 12; branch pipes 16 for removal of the clarified liquid in which the hydraulic lock 17 is arranged. For removal of the purified gas, the branch pipe 18 of the gas outlet is installed, and the nozzle 19 is used to remove sludge from the device.

The device works as follows.

The pressure hydrocyclone 1 from the ejector 2 through the inlet pipe 3 under pressure enters the mixture of gas, water, coagulant solution prepared in the ejector 2, as well as the polydisperse solid particles and particles enlarged under the action of the coagulant (flocculant) in it in separator 4 The contactor gas enters the ejector 2 through the nozzle 5 through the nozzle 6, and the contaminated water through the nozzle 7 and the additional nozzle 8. The gas and water jets emerging under pressure from the nozzles 6 and 8 and entering the vacuum chamber of the ejector 2, directed to one side and in contact with each other. In this connection, the optimal average speed of the entry of the hydroelectric mixture into the hydrocyclone 1 is maintained, and if the jet velocity of one of the two components of the mixture (water or gas) for some reason decreases for a time, then the average rate of flow of the mixture in the hydraulic system 1 is maintained sufficient , so that the process of its purification from suspended substances takes place. In order for this process to take place efficiently into the ejector 2, through the pipe 9, a coagulum solution (phpool nta) is entrained, which is mixed. It is located in the ejector 2 with a gaseous stream and with solid particles in it. The crustiness of these particles is different: those that come with gas and water are small and medium-sized, and from separator 4 they come

large particles resulting from coagulation. Spinning the flow of such a mixture in hydrocyclone 1, large particles carry some small and medium particles, press centrifugal force to its wall, move along a helical line down to the discharge opening, and a mixture of water and gas through pipe 10 attached to the conical bottom. 11, in which the bath 12 is formed, flows from the hydrocyclone 1 to the separator 4. In the separator 4 there are two processes: the coarsening of particles as a result of coagulation and the separation of particles and water from gas. The magnitude of the enlarged particles depends on the dose of the reagent, on the degree of their mixing with the reagent, and on the duration of the process of enlargement of the particles. Out of pipe 10, a mixture of gas and water meets on its way

umbrella 13 and changes the direction of movement, oh

neither by 180. In this case, the solid particles contained in the mixture and water are from

are made of gas and enter the bath of 25 women with a pipeline, connecting the separator with a vacuum chamber of the ejector equipped with a reagent supply nozzle attached to the bottom of the separator by a cyclone with the inlet pipe,

30 connected to an ejector and an outlet pipe communicating with the celarator space and provided with an umbrella, the liquid supply nozzle installed in the vacuum chamber of the ejector.

2. Device POP.1, OTLI12. In bath 12, solids settle to the bottom, and the clarified water is at the top. From the bath 12, the sediment is sucked through the pipeline -14 through the slot 15 into the vacuum chamber of the ejector 2. The clarified water is discharged from the separator 4 through the pipe 16, which has a hydraulic lock 17, which maintains a constant water level in the bath 12. Separated from the separator 4 from the water the gas cleared from contamination is removed from the device through the pipe 18, and the contamination is removed through the nozzle 19.

Of course, the liquid outlet pipe is equipped with a hydraulic seal.

By connecting the hydrocyclone and the ejector to the separator, the liquid is highly efficiently cleaned while the sediment is removed and the separator is connected to the hydrocyclone through the bottom through a pipe with a vacuum chamber of the ejector, which also leads to an increase in the effect of cleaning the liquid. gas purification remains high enough.
