Multistage filtering type waste gas purifying device

Abstract

The invention discloses a multistage filtering type waste gas purifying device. The multistage filtering type waste gas purifying device comprises a body, wherein the body comprises a sedimentation chamber, a purifying chamber, gas inlets and a gas outlet, wherein the sedimentation chamber is arranged below the body; the gas inlets are symmetrically arranged at two ends of the sedimentation chamber which is internally provided with a plurality of dust blocking plates which are arranged uniformly; the top end of the sedimentation chamber is connected with the lower part of the purifying chamber via a gas intake pipe; the bottom of the purifying chamber is provided with a liquid storage tank; a liquid charging opening is formed in one side of the liquid storage tank; the left and right sides of the liquid storage tank are respectively connected with a guide pipe; the guide pipe extends from the outer wall of the purifying chamber and is connected with a plurality of spraying heads arranged in the purifying chamber; a first filtering plate is arranged above the liquid storage tank; tow ends of the first filtering plate are respectively provided with oil water separators; a second filtering plate is arranged above the first filtering plate; an active carbon filter layer is arranged above a main spraying pipe; a buffering device is arranged between the precipitation chamber and the purifying chamber; the outer wall of the purifying chamber is provided with a support. The multistage filtering type waste gas purifying device has the advantages of good purifying effect, convenience in use and the like.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an exhaust gas purification device. Background technique [0002] At present, industrial waste gas is a major source of pollution. Various toxic and harmful gases contained in industrial waste gas, such as sulfur dioxide and hydrogen sulfide, pollute the atmospheric environment, and some particles also cause serious air pollution to the public environment. As one of the main sources of air pollution, industrial waste gas has a great destructive effect on the living environment of human beings. Therefore, it is very important to effectively treat industrial waste gas so that it can meet the appropriate emission requirements before entering the atmospheric environment. The practical significance of the Chinese patent literature discloses a patent for an exhaust gas purifier with the application number CN201420148308.6, which is composed of a first-level exhaust gas treatment chamber...

[0002] At present, industrial waste gas is a major source of pollution. Various toxic and harmful gases contained in industrial waste gas, such as sulfur dioxide and hydrogen sulfide, pollute the atmospheric environment, and some particles also cause serious air pollution to the public environment. As one of the main sources of air pollution, industrial waste gas has a great destructive effect on the living environment of human beings. Therefore, it is very important to effectively treat industrial waste gas so that it can meet the appropriate emission requirements before entering the atmospheric environment. The practical significance of the Chinese patent literature discloses a patent for an exhaust gas purifier with the application number CN201420148308.6, which is composed of a first-level exhaust gas treatment chamber, a filter chamber and a solution circulation box. Reduction into harmless gas or into sediment, the slag outlet of the filter is opened to discharge the sediment, and the sediment is transported away through the conveyor belt, but this exhaust gas purification device is not effective because of its simple structure To achieve a good exhaust gas purification effect, there will still be incomplete purification after the purification is completed, which will cause secondary pollution of the environment, and will also increase the cost of the enterprise
