Full-water-leaching washing-type gas filter

Abstract

The invention relates to a full-water-leaching washing-type gas filter. The full-water-leaching washing-type gas filter comprises a cylinder body and a cylinder cover can be fixed on the upper edge of the cylinder body in a matched sealing mode and can be opened and closed; a gas exhaust opening is formed in the upper part of the side wall of the cylinder body; an adsorption liquid inlet and outlet is formed in the lower part of the side wall of the cylinder body; and the cylinder body is composed of a gas filtration chamber at the upper part and a gas water leaching adsorption chamber at the lower part. The full-water-leaching washing-type gas filter provided by the invention can fully adsorb harmful substances in waste gas, is simple and easy to operate, is convenient to maintain, omits water pumping and spraying by a water pump in the prior art, and saves the production cost.

Description

technical field [0001] The invention relates to a gas filter device, in particular to a fully water-immersed scrubbing gas filter. Background technique [0002] The notice of the State Council on the Air Pollution Prevention and Control Action Plan has been used as a guideline for the current and future national air pollution control work. The state plans to use 5 years or more to gradually eliminate polluted weather; In several provinces or municipalities directly under the Central Government, the central government plans to allocate 5 billion yuan to allocate funds in exchange for subsidies, which fully proves the importance of protecting the atmospheric environment. [0003] At present, the equipment mainly used to treat exhaust gas in China is a counter-flow adsorption tower. Its structure includes a sealed tower body, an air outlet at the upper end of the tower body, an exhaust gas inlet at the lower end of the tower body, and a liquid spraying tower in the middle of th...

Problems solved by technology

[0003] At present, the equipment mainly used to treat exhaust gas in China is a counter-flow adsorption tower. Its structure includes a sealed tower body, an air outlet at the upper end of the tower body, an exhaust gas inlet at the lower end of the tower body, and a liquid spraying tower in the middle of the tower body. The liquid spray device is connected with the peripheral pump body through the pipeline. When the exhaust gas is sprayed upward from the bottom of the tower, the liquid spray device starts to work and sprays the mist adsorption liquid to the lower part of the tower body, so that the waste gas and the mist liquid are in contact. And react, in order to achieve the effect of eliminating harmful exhaust gas, after contacting the gas after the reaction, the gas outlet on the top of the tower is ejected; the actual operation proves that the contact time of the adsorption tower with this structure is too short due to the short contact time between the liquid and the harmful gas (the liquid falls due to gravity) , the gas is sprayed upwards, and the combination time of the two is extremely short), the harmful gas cannot be completely soaked in the adsorption liquid to fully absorb the harmful gas and remove it, so only a small amount of harmful gas can be removed, and the working efficiency of the counter-flow adsorption tower is not high. High, and the adsorption tower needs to use a water pump to spray mist adsorption liquid into the tower, resulting in an increase in working costs
