METHOD OF THE AIR PURIFICATION BY THE WET DUST TRAPPING IN THE VIBRO-BOILING LAYER OF THE LIQUID AND THE DEVICE FOR ITS REALIZATION Russian patent published in 2006 - IPC B01D47/02 B01D53/18 

FIELD: chemical industry; textile industry; alimentary industry; light industry; light industry; other industries; methods and devices of the wet dust trapping.

SUBSTANCE: the invention is pertaining to the method and the device for the air purification by the wet dust trapping and may be used in chemical, textile, alimentary, light and other industries for purification of the dusty gases. The method of the air purification provides that the polluted gas stream is fed through the inlet branch pipe arranged into the device body. At that one of the branch pipe cuts is placed with a clearance above the surface of the liquid in the tank and create the fluidization of the liquid with formation of the gas-liquid suspension. Then withdraw the gas-liquid suspension into the separator of the liquid phase, make the gas stream free from the drips of the liquid and withdraw it through the outlet branch pipe, and the formed slime withdraw through the pipe arranged at the bottom of the body. The polluted gas stream is fed through the cylindrical branch pipe and in the upper layers of the liquid place the vibrator and fix it to the body by means of the resilient perforated diaphragm, and the formation of the gas-liquid suspension additionally intensify by formation of the vibro-boiling layer in the upper layers of the liquid. The device of the air purification contains the body, the branch pipe for the dusty gas feeding and the branch-pipe for withdrawal of the purified gas, the tank with the liquid, the sluice nozzle and the pipe for the slime withdrawal. At that the branch pipe for feeding of the dusty gas is made cylindrical, and in the upper layers of the liquid there is the vibrator fixed to the body by means of the resilient perforated diaphragm. The technical result of the invention is the increased efficiency and reliability of the process of dust trapping.

EFFECT: the invention ensures the increase of the efficiency and reliability of the process of dust trapping.
