Efficient self-cleaning water curtain type waste gas multi-stage filtering method

Abstract

The invention discloses an efficient self-cleaning water curtain type waste gas multi-stage filtering method, which belongs to the field of waste gas filtering, and comprises the following steps of: introducing waste gas into a filtering device, and driving a multistage filtering cylinder to rotate under the airflow action of the waste gas. The multistage filter cartridge is continuously impactedby airflow generated when waste gas is introduced, the multistage filter cartridge is driven to continuously rotate inside, adsorption liquid continuously flows down in the multistage filter cartridgeto form multiple water curtains, the waste gas is sequentially filtered for multiple times by the multistage filter cartridge and adsorbed and separated by the multiple water curtains from outside toinside, the multistage purification process of waste gas is realized, and in the rotating process of the multistage filter cartridge, the two processes of filtering and cleaning of the multistage filter cartridge are synchronously carried out through the automatic cleaning of a single-layer cleaner and a double-layer cleaner, so that the continuous and efficient purification process of the wastegas is realized.

Description

technical field [0001] The invention relates to the field of waste gas filtration, and more specifically relates to a high-efficiency self-cleaning water curtain type waste gas multi-stage filtration method. Background technique [0002] Industrial waste gas refers to the general term for all kinds of pollutant gases that are discharged into the air during fuel combustion and production processes in the enterprise factory area. These exhaust gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (mist) lead mercury, beryllium compounds, smoke and productive dust, which will pollute the air when discharged into the atmosphere. These substances enter the human body through the respiratory tract in different ways, some directly cause harm, and some have a cumulative effect, which will seriously endanger human health. Industrial waste gas treatment refers to the pretreatment of wa...

Problems solved by technology

[0003] For the treatment of particulate pollutants such as smoke and dust contained in exhaust gas, filtration is generally used for purification, but in filtration treatment, the most common problem is the blockage of filter equipment caused by particulate matter, which not only interrupts the purification process, but also seriously reduces the purification process. Efficiency, and also makes exhaust gas filtration less effective
