Description
Technical Field
The invention relates to the technical field of waste gas treatment equipment, in particular to a waste gas treatment device containing oil-water mixture.
Background
The filter cartridge dust remover is widely applied to the industrial fields of cement, steel, electric power, food, metallurgy, chemical industry and the like, the whole capacity is increased by several times, the large-scale dust remover with the filtering area larger than 2000 square meters (GB 6719-86 types) is formed, the best scheme for solving the problems of difficult collection of ultrafine dust, high filtering wind speed, poor dust removing effect, easy abrasion and leakage of a filter bag and high operation cost of the traditional dust remover is provided, and compared with various existing bag-type and electrostatic dust removers in the market, the large-scale dust remover has the characteristics of large effective filtering area, low pressure difference, low emission, small volume, long service life and the like, and the large-scale dust remover becomes a new direction for the development. But cannot filter the exhaust gas containing oil and water due to the material and structure of the filter cartridge. If the filter cartridge dust remover adsorbs water vapor and oil mist dust, the filter cartridge will be attached to the filter cartridge, and the pulse back blowing cannot drop the dust, so that the filter cartridge is scrapped.
The dry cyclone dust collector is widely applied to working conditions with high dust concentration, and is mainly suitable for purifying non-viscous and non-fibrous dry dust with the dust concentration of more than 5-10 microns. The cyclone dust collector is a purification device with simple structure, convenient operation, high temperature resistance and lower equipment cost and resistance, and the cyclone dust collector is most widely applied to the purification device. The cyclone dust collector has the advantages of simple structure, small volume, no need of special auxiliary equipment, low cost, moderate resistance, no moving parts in the dust collector, convenient operation and maintenance and the like. The cyclone dust collector is generally used for collecting particles with the particle size of more than 5-15 microns, the dust collection efficiency can reach more than 80%, and the dust collection efficiency of a specially-made cyclone dust collector improved in recent years can reach more than 85%. The disadvantage is that it is not possible to treat the exhaust gas containing oil mist and moisture.
The bag type dust collector is a dry type dust filtering device. It is suitable for trapping fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, the dust-containing gas is filtered by the filtering action of the fiber fabric, after the dust-containing gas enters the bag type dust collector, dust with large particles and large specific gravity falls into the dust hopper due to the sedimentation of the gravity, and when the gas containing fine dust passes through the filter material, the dust is blocked, so that the gas is purified. The method has the defects that waste gas with high moisture content cannot be treated, and the waste gas with high moisture content can cause the filter bag to be bonded and block the filter material, so that the filter bag is scrapped.
In summary, the filter cartridge dust collector, the dry cyclone dust collector and the bag type dust collector all have the defect that the waste gas containing oil and water cannot be treated, so that the application of the filter cartridge dust collector, the dry cyclone dust collector and the bag type dust collector in the filtration industry is greatly limited, and the problem of treatment of the waste gas containing oil and water is also brought.
