SCRUBBER Russian patent published in 2006 - IPC B01D47/06 B01D53/18 

FIELD: chemical industry; textile industry; alimentary industry; light industry; other industries; equipment for wet dust trapping.

SUBSTANCE: the invention presents the scrubber for the for wet dust trapping and may be used in chemical, textile, alimentary, light and other industries to purify the dusty gases. The scrubber contains: the body, which has the conical and cylindrical parts and the slime-collector; the connecting pipe for the dusty gas inlet; the connecting pipe for the purified gas outlet; the spraying device including the external pipelines with the lower and upper nozzles cut in the body. The spraying device is made in the form of at least two external pipe ducts coupled to the common supply of the liquid, each of which has the cut in the body lower and upper nozzles having the opposite directions of the twist of the spraying liquid coming out of the spraying device. The nozzles of the spraying device are made in the form of the hollow closed on the one side cylindrical chamber having the tangential longitudinal groove for the liquid outlet. The ratio of the device diameter D to the diameter_{of the inlet connecting pipe Do is in the optimal interval of the values:D/DO = 2.2... 2.5, and the ratio of the device height H to the diameterof the inlet connecting pipe Do is in the optimal interval of the values:H/Do=4.8... 5.7. The technical result of the invention is the increased efficiency and reliability of the dust trapping process.}

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