Post dust is managed, one of the most common dedusting method is bag-type dust,
However, bag-type dust has some defects since own structural characteristics determine it necessarily, cloth bag volume is larger,
It is the case where certainly existing discontinuity equalization, higher so as to cause cloth bag damage rate under the higher gas shock of temperature, Er Qiegeng
It is comparatively laborious to change maintenance process, so in fact many manufacturers all work in the case where dust removal by filtration equipment is impaired, directly
To green audit next time, although way remains to be discussed, the difficulty faced is it will be apparent that mainly repair and replacement
Economic cost and time cost it is excessively high, general enterprises are difficult to bear, for this purpose, inventor wishes to design a kind of completely new dedusting
Cleaning equipment, to overcome the defect of existing dust separation device；
It finds after study, filter structure can be with the particulate matter in adsorbed gas, and solution or common water are also can be with
The particulate matter carried in air is left by way of dissolving or washing away；It is introduced into water when the air containing particulate matter
When, air is so that existing for biggish bubble form, smaller with the contact area of solution or water, time of contact is shorter, air
The particulate matter of middle carrying seldom can be dissolved or be washed away by solution/water, so how to make air in the form of minute bubbles and solution
Or water contact is to restrict the key factor of cleaner success or not in this；
In addition, the air for carrying impurity passes through liquid, after dissolution is washed away, most of impurity dissolves in a liquid,
Or suspension is formed in a liquid, but some impurity is wrapped up and floated on a liquid by bubble, when subsequent air
By when, can acutely roll at liquid surface, scene when similar to liquid boiling, but the gas for being coated with impurity at this time
Bubble and the impurity for forming suspension may all be rolled at the top of liquid level and contact with the air at the top of liquid level, finally turn again to sky
In gas, so finally obtained air purification effect is not ideal enough, thus, if it is possible to by liquid and the sky Jing Guo liquid handling
