Gas scrubber

Abstract

Disclosed is a gas scrubber. According to the gas scrubber, an air inlet pipe and an anti-overflow hopper are arranged in a tank, the space, above the anti-overflow hopper, inside the tank serves as an air collecting chamber, the space, below the anti-overflow hopper, inside the tank serves as a water containing scrubbing chamber, a pressure plate is arranged on the outer edge of an air outlet of the air inlet pipe, a cylindrical filter element is arranged in the scrubbing chamber and is composed of multiple metal or plastic hoops sleeved together, a brush layer is arranged on the outer surface of the filter element, the portions, located on the upper surface and lower surface of the filter element, of the brush layer are in pressure connection with the bottom surface of the pressure plate and the inner bottom surface of the tank movably respectively, and the air collecting chamber is communicated with an exhaust pipe. Gas is squeezed and separated into numerous tiny bubbles after passing through the multiple hoops in the filter element and the brush layer. In this way, water can adsorb dust and impurities in gas effectively, the gas filtering effect is good, dust adsorbed by water can deposit to the bottom the tank, dirty liquid can be discharged simply by opening a drainage valve port on the bottom of the tank when maintenance is conducted each time, then pure water or anti-freezing solution is replenished, and therefore maintenance is easy. Compared with a dry type filter screen, the gas scrubber has the advantage that water using cost is lower.

Description

technical field [0001] The invention relates to the field of gas purification equipment for internal combustion engines, in particular to a gas scrubber. Background technique [0002] The air filter used in the existing internal combustion engine captures the dust and impurities in the gas through a multi-layer dry filter. The disadvantage is that when purifying the gas with a lot of dust and debris, the filter will be blocked soon, so that the gas can circulate. The filter effect becomes worse as the resistance increases, and even the filter fails when the filter screen is clogged seriously. In order to ensure the gas purification effect, the filter needs to be maintained regularly, but the dry filter screen in the filter is mostly disposable. Products can only be discarded and replaced with new ones, which is cumbersome to maintain and uneconomical to use. Contents of the invention [0003] The object of the present invention is to provide a gas scrubber. The gas scrubb...
