Problems solved by technology

[0004] There are many disadvantages in the above-mentioned technical solution. First, the structure is complicated, the precision requirement is high, it is easy to be damaged, the service life is low, and the production cost is increased; secondly, the equipment does not use circulation filtration, and the filtration effect of the filter layer will decrease obviously after a period of use. To achieve the expected effect, at the same time, the wastewater in the filter pool group has not been treated, which will not only increase the cost, but also cause waste and pollution of water resources

Abstract

The invention discloses waste gas filtering equipment, which comprises a main box, a spray cooling system, a filtering system, a scrubbing water box and an oil and water separation circulating water box, wherein the main box comprises a gas inlet and a gas outlet, and the scrubbing water box is positioned on the lower part of the main box; the spray cooling system comprises spray frames, the filtering system comprises rollers and a filtering cloth curtain, the spray frames of the spray cooling system are respectively positioned below the filtering cloth curtain of the filtering system, the rollers are arranged on two side walls of the main box, and the filtering cloth curtain is wound on the rollers back and forth; the two rollers positioned on the lowermost parts of the two side walls are connected with a power system, and the filtering cloth curtain passes through the scrubbing water box; and the scrubbing water box is connected with the oil and water separation circulating water box through a return water pipe. The waste gas filtering equipment has the advantages of simple structure and low equipment investment cost, a circulating and filtering system is adopted, hairs, spandex oil and air particle impurities in waste gas can be effectively removed, and the waste gas filtering efficiency is improved.

Description

technical field [0001] The invention relates to an exhaust gas treatment system, in particular to an exhaust gas filtering device. Background technique [0002] Waste gas treatment refers to the pretreatment of waste gas generated in industrial sites and factory workshops before being discharged to the outside, so as to meet the national standards for external discharge of waste gas. At present, the spray towers used by exhaust gas filtration equipment in the traditional market are only equipped with baffles in the tower body to allow exhaust gas to pass through, and sprinklers are installed above the baffles. This type of waste gas filtration equipment only performs simple and rough filtration on the waste gas, and can only filter out large particles of waste residue, but cannot effectively filter out small particles of impurities in the waste gas. Secondly, for different types of waste gas, especially complex and difficult Filtered exhaust gas cannot achieve satisfactory ...
