The receiving electrode of the cathode device extends to the position under the bottom end of the smoke outlet; and the collected liquid is effectively prevented from being carried by smoke for the second time, and the removal efficiency of the downstream wet electrostatic precipitator is ensured.
Description
One, technical field
The utility model belongs to environmental protection equipment, relates to a kind of following current wet electrostatic demister that is used for gas purification.
Two, background technology
With the matching used wet electrostatic demister of large-scale wet desulphurization device be a kind of device that removes multiple pollutant of uniting, can effectively remove the SO in the flue gas after desulfurization
3, NH
3, particulates such as fine dust (PM2.5), fine drop, mercury, make the outlet flue gas be in acid mist almost by the state of whole removals, reduced SO effectively
3The corrosion rate that the acid mist condensate liquid causes back-end ductwork and chimney, and greatly reduce the turbidity of flue gas, efficiently solve chimney " Mao Baiyan " and the problem of descend slowly and lightly " gypsum rain ".
Place in the absorption tower or place outside the absorption tower according to the wet electrostatic demister, can the wet electrostatic demister be divided into reverse-flow and two kinds of downflow types.
Reverse-flow be with the wet electrostatic demister place in the absorption tower, the top of spraying layer, make an integral body with the absorption tower, flow of flue gas direction wherein is opposite with the flow direction of collecting liquid.This pattern generally is applicable to newly-built desulfurizer, and more to the change of absorption tower and clean flue if be applied in the transformation project, the improvement project amount is bigger.
Downflow type is after the wet electrostatic demister is arranged in the absorption tower as a self-contained unit, and is separate with the absorption tower, and flow of flue gas direction wherein is identical with the flow direction of collecting liquid.This pattern is arranged comparatively flexible, generally is applicable to the desulfurizer of transformation.
Following current wet electrostatic demister will produce the secondary of collecting liquid at smoke outlet like this and carry structurally with reverse-flow identical in the past, had reduced the removal efficiency of electrostatic precipitator indirectly.
Three, utility model content
The purpose of the utility model is to solve the problem of smooth wet electrostatic demister secondary band water, utilizes receiving electrode to collecting the guide functions of liquid, and a kind of following current wet electrostatic demister that has flow-guiding structure is provided.
The utility model is made up of gas approach, housing, receiving electrode device, cathode assembly, collecting tank, exhanst gas outlet.The receiving electrode device comprises receiving electrode and upper support element, lower support, and cathode assembly comprises cathode line, top fixed frame, bottom fixed frame, insulated case.Receiving electrode extends to the bottom of exhanst gas outlet with upper/lower positions always, and deposition is very collected the guiding device of liquid.
The utility model is realized through following mode:
Receiving electrode adopts light flexible film or electroconductive frp, has advantages such as conducting electricity very well, be prone to flushing.
The fixed form of frame fixation was all used at two ends about cathode line adopted, and framework supports through insulated case, and suspension rod adopts the quartz ampoule support in the insulated case.Is furnished with electric heater unit in the insulated case, to guarantee that cathode assembly constantly and receiving electrode and the tower body state of insulation that keeps dry.
Flue gas after desulfurization gets into wet electrostatic demister, the SO in the flue gas from upper inlet
3, NH
3, particulate such as fine dust (PM2.5), fine drop, mercury charged after, under the effect of Coulomb force, high-voltage electrostatic field, be collected into receiving electrode.Collect liquid and under the effect of gravity, flow downward, get into the collecting tank of bottom along receiving electrode.Because receiving electrode extends to below the bottom of exhanst gas outlet always, deposition is very collected the guiding device of liquid, so effectively avoided being carried by the flue gas secondary from the collection liquid that the receiving electrode bottom discharges, has guaranteed the removal efficiency of following current wet electrostatic demister.
Four, description of drawings
Fig. 1 is a kind of structural representation of following current wet electrostatic demister, and Fig. 2 is the inner plan structure sketch map of wet electrostatic demister, and wherein: 1 is gas approach; 2 is housing; 3 is insulated case; 4 is cathode line, and 5 is receiving electrode, and 6 is collecting tank; 7 is the receiving electrode lower support, and 8 is exhanst gas outlet, and 9 is cathode line bottom fixed frame, and 10 is the receiving electrode upper support element, and 11 is cathode line top fixed frame.
Five, the specific embodiment
Provide the embodiment of the utility model below in conjunction with accompanying drawing.
The flue gas that contains various particulates after the desulfurization gets into the wet electrostatic demister through gas approach 1; Receiving electrode 5 is fixing with receiving electrode lower support 7 through receiving electrode upper support element 10; Cathode line 4 is fixing with cathode line bottom fixed frame 9 through cathode line top fixed frame 11; Dc high-voltage acts on the cathode line 4 through insulated case 3; Form corona discharge region and receiving electrode 5 formation stable high voltage electrostatic fields, and realize the insulation between cathode line 4 and the housing 2; With flue gas get into the various particulates of wet electrostatic demister charged after, the effect in the Coulomb force, high-voltage electrostatic field is collected into receiving electrode 5, collects liquid and under the gravity effect, flows downward along receiving electrode 5, gets into the collecting tank 6 of bottom; Collection liquid in the collecting tank 6 passes through pipeline self to melt pit, by the desulphurization system Unified Treatment; Flue gas after the processing passes to smoke stack emission through exhanst gas outlet 8.
