Description
Technical field
The present invention relates to demisting field more particularly to a kind of rotary flue gas demisters.
Technical background
According to national requirements for environmental protection, the content that industrial vision pollution is also put into environmental protection of enterprise improvement is eliminated.To elimination work
Vapor in industry flue gas, method general at present are that demister is installed in flue.The structure of existing demister mainly by
Plate, supporting arrangement are constituted.Demisting purpose is completed by plate.Plate usually by high molecular material (such as polypropylene PP, FRP) or
Stainless steel two major classes material is made, and is hard.It is generally divided into streamlined and broken line type.Its working principle is that when containing
When the gas of mist flows through demister with certain speed, since the inertial impaction of gas acts on, mist and plate collide and by
Poly- drop arrive greatly its own generation gravity be more than gas climbing power and surface tension of liquid resultant force when, drop is just from plate
It is separated on piece surface.Since the workpiece plate as demisting is solid and does not have a suction-operated to fog,
Thus the efficiency of demisting and effect are frequently not that very well, the white cigarette emerged in current each chimney just illustrates this problem.In addition,
Sometimes to contain a large amount of dust, the problem of existing demister not can solve dust emission in flue gas.
