It is dynamic, while flue gas also flows from top to bottom, collection liquid is identical as flow of flue gas direction；Cross-flow refers to that collection liquid flows from top to bottom
It is dynamic, and flue gas bottom horizontal flow sheet, collection liquid and flow of flue gas direction are staggered.
In three of the above arrangement, in the identical situation of design parameter, the treatment effect of reflux type is more excellent.But nothing
By which kind of processing mode, low temperature electrostatic adsorbent equipment generally can all be connect with insulated case, and moist flue gas conduction occurs in order to prevent
Danger, insulated case is generally disposed at low temperature electrostatic adsorbent equipment upper end, and four or two insulated cases are arranged, using cloth outside tower
Mode is set, above-mentioned arrangement takes up a large area, while the box bracket that insulate increases certain investment cost.Especially for some small
There is the phenomenon that can not installing in type place.
