Description
Technical field
The present invention relates to technical field of environment protection equipment, particularly relate to the convenient type positive plate assembled unit for Wetting electrostatic cleaner.
Background technology
Along with social industrial development improves constantly, production scale constantly expands, and the flue gas entering air also gets more and more; Wherein, the problem containing PM2.5 is especially serious.Therefore, when meeting production capacity, how effectively purification enters the flue gas of air, reduces environmental pollution and becomes the hot spot of society.
The main fiber bag precipitator of equipment in the market for absorbing PM2.5, electric-bag complex dust collector, spray type dust separator, dry method electrostatic precipitator, Wetting electrostatic cleaner etc.Wherein fiber bag precipitator and electric-bag complex dust collector all will face pumping resistance greatly, and energy consumption is large, and the high operating cost problem of cloth bag infringement and replacing; Spray type dust separator spray face water consumption is large, needs sewage disposal after spray, and the problem of efficiency of dust collection instability; Dry method electrostatic precipitator, due to the charged difficulty of PM2.5 molecule, positive plate catches the problem of difficulty, inverse corona effect and reentrainment of dust etc., greatly limits the ability that it processes superfine micronic dust; Therefore the main flow treatment technology for PM2.5 is the terminal purifying process adopting Wetting electrostatic cleaner to carry out superfine micronic dust.
The core technology of Wetting electrostatic cleaner forms electric field by the discharge electrode of inside and metallic plate, utilize the positive plate in electric field to the absorption of charged soot dust granule to collect flue dust, then by spray system, rinse positive plate with fresh fresh water (FW) and the flue dust of catching is removed.The wet cottrell positive plate of main flow domestic is at present combined as honeycomb fashion combination, and become regular hexagon to arrange, the advantage of this kind of arrangement can save material greatly under the prerequisite of the electric field and larger specific dust collection area that have relative ideal.The domestic regular hexagon that is assembled into by positive plate arranges it is realized by the method for welding at present.A set of wet cottrell has hundreds and thousands of groups of discharge electrodes and positive plate assembly, and therefore dress up cellular by whole for so various positive plate soldering group, its workload is sizable, and difficulty is large, precision is low, consumes a large amount of human and material resources.
Application number be 201420218181.0 utility model patent disclose a kind of positive plate plug-in unit for assembling wet cottrell, refer to Fig. 1, it is the structural representation of the insert body of this documents.This insert body 1 is sheet, insert body is provided with at least 2 socket joint grooves 2.Opening and the bottom of this socket joint groove 2 are wide, and its width is less than 3.0mm, and groove depth is less than 300mm.This plug-in unit can solve positive plate installation effectiveness low, transport loaded down with trivial details problem, but, because this insert body is sheet, furthermore the rigid such as positive plate material selection stainless steel or fiberglass reinforced plastics of main flow in the market, new technique then can select flexible fibrous material, no matter is which kind of material, run in installation process and Practical Project and be all difficult to ensure to seal between plate, thus extreme influence electric field is stablized, and occur that flue gas leaks from gap, affect dust removing effects; In addition, due to the opening of this socket joint groove 2 and bottom wide, cause after positive plate inserts, pull may occur moving of position once be subject to external force, because the environment for use temperature of wet cottrell is high, high humidity, acidity are high, positive plate material there will be cross section deformation, and the easy positive plate of Long-Time Service departs from this insert body and causes dislocation, and directly changing die opening affects dust removing effects.
