Operation principle：During purifying smoke, flue gas enters air inlet 111, through 112 (air flow method of the first airflow-distribution board
Plate is a kind of porous plate.Gas can be unevenly distributed simultaneously when flowing through the pipeline of different-diameter on the section in flow direction
Turbulent flow is generated, the effect of airflow-distribution board is that airflow balancing is distributed, prevents the air flow method of flue gas is uneven from dedusting being caused to be imitated
Rate declines) into electric precipitator 120, under the action of bent plate 191 windward and contrary wind bent plate 192, flue gas can smoothly but not
Too fast by the electric field between electrode plate 121, the dust of bulky grain can be adsorbed on electrode plate 121 in flue gas.Then flue gas is worn
The second airflow-distribution board 113 is crossed into each dirt pocket 131 of bag filter 130.Poppet 141 will be in air-purifying chamber 140
Gas imports outlet pipe 150, therefore forms negative pressure in air-purifying chamber 140 and dirt pocket 131, and flue gas passes through Bag filter device
132 enter air-purifying chamber and flow to outlet pipe 150, and the fine particle in flue gas is filtered by Bag filter device 132.
Flue gas enters expansion chamber 310 from intermediate conduit 200, and one is entered after 311 airflow balancing of the 3rd airflow-distribution board
Grade dirt pocket 320.Flue gas support rises plastic beads 363, since there is plastic beads 363 larger surface area and surface attachment to have
Moisture film (366 constant spray water of nozzle), flue gas flows through vulcanization gas therein during the gap between plastic beads 366 and cone-shaped wall
Body is just adhered to by the moisture film of bead surface, and flue gas subsequently enters two-stage dust removal room 330 (dust removal process is identical with primary dust removing room),
The steam in flue gas is removed by demister 340, is then discharged from outlet pipe 350.Due to /V net 364 limitation and
The small adsorption effect of flow velocity High Voltage, plastic beads is without departing from taper hole scope.
During net gas, the first soot cleaning valve 212, the second soot cleaning valve 151 and nozzle valve 164 are turned off.During deashing, above three
Valve is opened, and electric precipitator 120 is in off-position.Reciprocating apparatus 171 drives deashing bar 170 to vibrate back and forth simultaneously, deashing
Bar 170 drives Bag filter device 132 to rock by the linkage rope 172 of tensioning.In this way, electric precipitator 120 and bag filter
Dust on 130 falls into ash bucket 180.Meanwhile in gas wash tower 300, nozzle 366 continues spray water, washes away plastic beads 363,
The dust of bead surface finally flows into pond 312 and waits subsequent processing.
