Gas filter device

Abstract

The invention provides a gas filter device, belonging to environmentally-friendly facility. The device comprises an air inlet pipe, a gas extraction filter device, an absorption liquid circulating and draining device, an absorption liquid level control device and an electric appliance control and display device, wherein one end of the air inlet pipe extends into the middle part in a gas filter tank of the gas extraction and filter device, and extends upwards out of the surface of the absorption liquid; the gas extraction filter device is connected with the absorption liquid circulating and draining device and the absorption liquid level control device; the gas extraction and filter device comprises a wet filter tank, a dry type filter cylinder, a draught fan and a muffler; a solid-state substance settlement plate, an impact cap, a diversion angle and a filter plate are arranged in the wet-type filter tank; and the dry type filter cylinder, the draught fan and the muffler are arranged in a gas exhaust cylinder on the upper part of the wet filter tank in sequence. The gas filter device achieves the aim of waste gas filter by the technology of wet and dry double filtration.

Description

Technical field: [0001] The invention belongs to environmental protection facilities, and is mainly used for filtering non-organic complex component waste gas and dirty air, and specifically relates to a gas filtering device. Background technique: [0002] At present, there are many ways and devices for filtering exhaust gas, and the filtering effects are different. Among the many methods, the device used in the water washing method is simple and practical, and several existing wet processing devices are introduced below. [0003] The desulfurization treatment of industrial waste gas, the main process and equipment is to use the blower to send out the combustion gas, which is cooled by the cooling tower and then sent to the bottom of the absorption tower. The gas is absorbed by dilute sulfuric acid through the absorption tower and discharged into the atmosphere. To the oxidation tower, under the action of the catalyst, it reacts with the air in the oxidation tower to genera...

AI Technical Summary

Problems solved by technology

[0005] First, the gas treatment method is pure dry filtration or pure wet filtration, and the use function is relatively single. One system can only process one or several types of waste gas with similar properties, and its adaptability is narrow

[0006] Second, the spray system adopted has poor gas-liquid mixing degree, poor filtering effect and solid particle falling effect, and the spray atomizing head is easy to be blocked, which requires high cleanliness of the spray liquid

[0007] Third, the fan is placed at the intake end of the filtration system. If the exhaust gas is corrosive, it will corrode the fan. If the exhaust gas contains solid particles, it will hit and rub and damage the fan blades, thereby shortening the service life of the fan.
