The work that environmental protection department all attaches great importance to.For the dust how eliminated in air, numerous solutions are had been proposed for both at home and abroad
Certainly scheme, by filtering air cleaning is realized, is one of the most commonly used several method, such as Application No.
The Chinese patent of CN201310016550.8, is that flour dust overflow is led when solving to be fed in various additive storehouses in mortar whipping process
Additive is caused to waste the problem with environmental pollution, it is proposed that one kind is filtered dust-contained airflow using filter element, Jing high pressure blowback pulses
The dust for leaching is discharged in additive storehouse, the mode that additive dust is recycled is realized；Application No.
The Chinese patent of CN200610030086.8, disclose it is a kind of by drainage screen pinching and process poisonous and harmful dust filtration dress
Put and filtration system；The United States Patent (USP) of Publication No. US8123840, describing a kind of granule by static electrification was carried out
Filter, the method so as to remove dust in air granule.
Need Jing often to change drainage screen in order to avoid dust removal by filtration, except the defect such as dust quantity is relatively low, in larger area yard
In institute, often using wet dust removal mode, i.e., using air of the solution washing containing surfactant containing dust granules, powder
Dirt is only absorbed by the water discharge, so as to obtain containing the relatively low pure air of dust.Wet dust removal mode includes foam dust-removing, gas sparging
Various dedusting methods such as dedusting are drenched in dedusting, water, and above-mentioned cleaner unit is utilized on the interface of drop, liquid film and bubble, fine dusts
The adsorption of diffusion and gas-liquid liquid on interface to dust, dust absorbing is entered in aqueous solution, reaches dedusting purpose.
It is net that the Chinese patent of Application No. CN200410014513.4 discloses a kind of waste gas being made up of aerosol chamber, expansion chamber and pond
Makeup is put, and the device carries out dedusting using the water smoke that the atomization device in aerosol chamber is produced, and completes aerosol sedimentation in expansion chamber, from
And reach dedusting purpose；The Chinese patent of Application No. CN201210226623.1 discloses a kind of utilization and sprays to dust collect plant
The exhaust gas and dust of collection carries out the dust arrester for washing and water smoke is processed.
However, often there is the defects such as dust collection capacity is relatively low, equipment operation is complicated in above-mentioned cleaner, it is difficult to meet 1000
In the even more big working space of square meter, the quick, requirement of high-effective dust-removing, design one kind disclosure satisfy that in larger work space efficiently
Dust removal requirement, cleaner easy to operate, are to eliminate working space middle and high concentration dust to the urgent of human body and environmental hazard
Demand.
