The specific embodiment
Embodiment
As shown in Figure 1 to Figure 3, the present embodiment discloses a kind of desulfurization and dedusting combination tower, in the bottom of tower body, is provided with desulfurization zone 1, top is provided with electrostatic precipitation district 2, the bottom of desulfurization zone 1 is provided with recycle slurry liquid pool 11, and middle part is provided with gas approach 12, and top is provided with spray-absorption layer 13.The coal-fired flue gas producing enters into desulfurization zone 1 from gas approach 12, now, alkaline absorption solution in recycle slurry liquid pool 11 is delivered to spray-absorption layer 13 by water pump, then is sprayed by the shower nozzle of spray-absorption layer 13 places setting, and absorption liquid absorbs the sulfur dioxide in flue gas.In recycle slurry liquid pool 11, be provided with agitating device 14, it stirs absorption liquid, and concentration is identical everywhere to impel the interior absorption liquid of recycle slurry liquid pool 11.
Flue gas is after desulfurization, and to the motion of tower body top, first it pass through the buffering of flue gas even distribution device 3, makes its speed steady, and air velocity is identical everywhere, then enters into electrostatic precipitation district 2 and carries out dedusting.At the top of tower body, be provided with exhanst gas outlet 25, by the flue gas after udst separation thus exhanst gas outlet be discharged from.The above and below in electrostatic precipitation district 2 is equipped with suspension bracket 23, and suspension bracket 23 is supported on tower body by insulated case 24, is provided with the heater that prevents these insulated case 24 dewfall humidities in insulated case 24.Between the suspension bracket 23 of upper and lower, be arranged with a plurality of anode tube 21, what these anode tube 21 adopted is remover of conductive glass steel tube, in each anode tube 21, be equipped with a cathode line 22, these cathode line 22 are keel prickle shape, or for the cutter shape of two sides band sword be catling shape, it is from anode tube 21 center is passed, and two ends are conveniently connected on the suspension bracket 23 of upper and lower.The cross section of anode tube 21 be inscribed circle diameter at the regular hexagon of 300-360mm scope, its length is 4500-6000mm.
These anode tube 21 close-packed arrays together, form three electric field regions, are respectively the first electric field region 26, the second electric field region 27 and the 3rd electric field region 28.It also can be divided into according to the size of tower body or other factors the electric field region of other quantity.The object that these electric field regions are set is in order independently to clear up each electric field region, for this reason, is provided with the flusher 4 of circulation flushing is successively carried out in these electric field regions above anode tube 21.When 2 work of electrostatic precipitation district, between cathode line 22 and anode tube 21, be connected with the voltage of 80KV, dust and various particulate, under the effect of highfield, are adsorbed on the inwall of anode tube 21.
After work a period of time, flusher 4 is started working, a plurality of shower nozzles are set above it, these shower nozzles face toward three electric field regions respectively, when the first electric field region 26 is rinsed, the shower nozzle corresponding with the first electric field region 26 started working, and now the circuit of the first electric field region 26 is cut off, other electric field region works, and pure water pours the dust on each anode tube 21 inwalls in the first electric field region 26 in recycle slurry liquid pool 11.The flushing process of other electric field regions is identical therewith.In flushing process, in each time, only have an electric field region to quit work, the exhaust gas volumn of electric field region discharge is less thus, and therefore, this desulfurization and dedusting combination tower is in the situation that guaranteeing safe operation, less to gas cleaning influential effect.
