Dust collection method with filtering liquid and device using the method

Abstract

The invention relates to a filterliquor dedusting method, which comprises the steps that firstly, flue gases are led into an air inlet pipe through a sealed liquid tank; secondly, a wind-delay device arranged inside the liquid tank is employed to cause the flow velocity of the flue gases to be reduced and flow close to liquid level; thirdly, a cyclone device arranged inside the liquid tank causes the flue gases after spinning to be discharged into the air through a discharge pipe. Since the flue gases are led into the sealed liquid tank, the flow velocity of the flue gases is reduced and the flue gases flow close to the liquid level after the flue gases are processed by the wind-delay device; as the liquid inside the liquid tank can absorb the soot of the flue gases, thus directly absorbing the soot of the flue gases into the liquid; the flue gasses spin through the cyclone device, which lengthens the flowing distance of the flue gasses inside the liquid tank, thus leading the flue gasses to fully contact with the liquid level. Therefore, a dedusting device is unnecessarily to be cleaned frequently, and the liquid inside the liquid tank is merely changed according to actual situations, thereby achieving the aim of dedusting at a time and having no secondary pollution. Besides, the invention further relates to a filterliquor dedusting device for the dedusting method.

Description

technical field [0001] The invention relates to a dust removal method and device, in particular to a dust removal method using the adsorption of liquid to smoke dust, and a liquid filter dust removal device using the dust removal method. Background technique [0002] There are many kinds of smoke and dust treatment devices in the prior art, and currently the most common ones are cartridge air filters and filter bag dust collectors. Both of these dust removal devices suck the air with smoke and dust into the dust removal device through the fan, and the smoke is directly discharged into the atmosphere after being filtered by the filter cartridge or filter bag. Chinese patent application CN200420032290.X disclosed a filter cartridge air filter on June 28, 2004, including a frame, a body placed on the frame, an ash hopper with an air inlet, and an injection system. The body is divided into a dust chamber with a filter cartridge inside and a clean room with an air outlet. The f...
