Description
Technical field
The utility model relates to a kind of demister for drop in flue gas and minute solid particles thing, especially relates to a kind of wet type electrostatic precipitator of compound concentric round shape collecting plate, belongs to technical field of dust removal equipment.
Background technology
Demister is used to the demister of drop and the micro-solid particle carried secretly in separating flue.Traditional mechanical type demister is arranged on desulfurizing tower top, is typically provided to two-layer up and down.But at present, the effect of mechanical type demister is undesirable, can only remove 40
μthe droplet of more than m, limited to the removal effect of fine droplets and solid particulate matter, can not remove the aerosol in flue gas, smoke evacuation turbidity is high.
Summary of the invention
The purpose of this utility model is the deficiency solving current technology, a kind of composite plate electrostatic precipitator of vertical layout is provided, utilize this demister to remove fine particle, heavy metal in flue gas, and catch with the various pernicious gases that aerosol form exists in flue gas, as SO
3, NH
3deng, increase substantially demister efficiency.
The high-efficient defroster that the utility model provides a kind of demisting efficiency to increase substantially.
Main technical schemes of the present utility model: compound concentric round shape wet type electrostatic precipitator, comprise housing, housing is provided with air inlet, gas outlet and insulated case, the built-in some collecting plates of housing and cathode line, it is characterized in that described collecting plate is compound collecting plate, be made up of straight concentric circles section and ripple concentric circles section; Some collecting plates in concentric arrays, are connected with housing by support system in housing; Uniform cathode line between collecting plate, cathode line connects insulated case.
Usually, with the hook and the thorn that catch particle in the ripple concentric circles section of described compound collecting plate.
Described cathode line be fixed in upper and lower frames by tube connector, gather to external insulated case.
With prickle in described cathode line.
For further illustrating the technical solution of the utility model, introduce operation principle of the present utility model in detail below.The utility model, in conjunction with electrostatic precipitator and wet type mechanical type demister advantage separately, forms a kind of high efficiency demister of associating demist.
First, electricity day with fog operation principle is by electrostatic control means and high direct voltage generating means, alternating current being become direct current delivers in demister, powerful electric field is formed between cathode line and collecting plate, air molecule is ionized, produce a large amount of electronics and positive and negative ion instantaneously, these electronics and ion do directed movement under the effect of electric field force, constitute the medium of trapping fine particle.Make particulate charged, these charged minuteness particles, under the effect of electric field force, are done directed movement, are arrived on collecting plate simultaneously.Afterwards, charged particle discharges electronics on pole plate, so fine particles etc. are gathered, rinse water flows by action to storage acid tank in, so just reach the object of purifying smoke.
On the other hand, the principle of mechanical demister is: when the droplet in flue gas and micro-solid particle are by blade in wave shape, impinge upon on blade, trapped by blade under the effect of inertia force, realizes and being separated of flue gas.
The utility model is the advantage in conjunction with electric demist and mechanical demist, fine particle is first through the flat segments of control of dust composite plate, charged after cathode line electric discharge, major part particle is caught by collecting plate and cleans, the particle that fraction is escaped is through corrugated plating, and because of charged, its probability clashing into coalescence increases greatly, subparticle coalescence is bulky grain, thus is caught by the thorn on collecting plate and hook.Meanwhile, deduster adopts lower air inlet mode, makes full use of Action of Gravity Field, reduce further the flow velocity of flue gas, extend the time of staying of flue gas in deduster.
The utility model can reach the object of associating demist, and demisting efficiency can be improved significantly.
This demister adopts current to rinse, and does not have rapping apparatus, avoids the generation of reentrainment of dust.
This demister also can reach higher except fog effect under the swiftly flowing operating mode of flue gas, is applicable to the situation of smoke inlet flow velocity 3 ~ 4m/s, meets the actual operating mode of power plant.

Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail.
Embodiment: compound concentric round shape wet type electrostatic precipitator structure is as shown in Fig. 1,2 and 4, mainly comprise housing 4, housing 4 is provided with air inlet 1, gas outlet 2 and insulated case 3, the built-in some collecting plates 10 of housing 4 and cathode line 6, its innovation is described collecting plate 10 is compound collecting plate, is made up of straight concentric circles section and ripple concentric circles section; Some collecting plates 10 in concentric arrays, are connected with housing 4 by support system in housing 4; Uniform cathode line 6 between collecting plate 10, cathode line 6 connects insulated case 3.
In embodiment, air inlet 1 is arranged on the lower left side of housing, and gas outlet 2 is arranged on housing upper right side, and compound collecting plate 10 leading portion is straight concentric circles, back segment is the concentrically ringed structure of corrugated, with hook 11 and thorn 12 in bellows segment; With prickle in cathode line 6, fix by upper cathode frame 5, lower cathode line framework 7 and be aggregated into insulated case 3.
Flue gas enters demister from air inlet 1, from bottom to top through the flat plate section of collecting plate, the drop in flue gas and fine particulates charged after the high-tension electricity effect in cathode line 6, and then to be caught by collecting plate 10.The particle that part is at large catches and drop are after the bellows segment effect of collecting plate back segment, and coalescence becomes bulky grain and caught by the hook 11 in bellows segment and thorn 12.
