Flue gas desulfurization is one of extensive control atmosphere pollution measure of adopting of present China power plant, at home in the thermal power plant, supporting desulfurization project all adopts the desulfurizer of bypass and GGH, after the desulfurizer fault, can open the bypass of desulfurizer, make the former flue gas of boiler be bypassed to chimney, and do not influence the safe operation of unit.But the setting of desulfurization bypass but causes the input of desulfurizer to can not get strict constraint, and then SO
2Discharging also can not get strict control, requiring of this and energy-saving and emission-reduction is inconsistent.Along with the requirement of environmental protection requirement raising and the operation maintenance of desulfurizer own, increasing power plant begins to adopt no bypass desulfurizer in recent years.The desulfurizer of no flue gas bypass is connected with boiler and is one, becomes the part in boiler cigarette air channel, is unique passage of fume emission, and the high operational percentage of desulfurizer is a key of guaranteeing the stable operation of boiler Host Security.
Boiler need be thrown oil when startup and low-load combustion-stabilizing operation combustion-supporting, because the desulfurizer of no flue gas bypass is unique passage of fume emission, its unburnt one-tenth branch enters the absorption tower of desulfurizer with boiler smoke, in the process that contacts washing with slurries, the greasy dirt in the flue gas is washed in the slurries of absorption tower; Oil pollution not only can make the slurries quality worsen as can not get timely solution, influences the desulfuration efficiency of desulfurizer, also will influence the safety of the stable and operation of desulphurization plant and system, also can force main shut-down system when serious, causes immeasurable loss.
Notification number is that the utility model patent of CN201454409U discloses a kind of flue gas mist cooling washing system, though can will be collected in the water tank after flue dust in the flue gas and the greasy dirt washing, directly do not enter the absorption tower, but because the water in the water tank recycles, oil water mixture is taken away by spray pump easily and is sprayed circulation, greasy dirt content increases gradually in the shower water, can influence the deoiling effect of washing system; Continuous operating time is long slightly, and along with the decline of washing system deoiling effect, the greasy dirt in the flue gas will enter the absorption tower with boiler smoke, and the oil pollution problem still can not thoroughly solve.
Summary of the invention
In view of this, the utility model provides a kind of flue gas mist cooling washing system, can avoid greasy dirt to enter the spray circulation once more, and system's long-play also can guarantee good deoiling effect, guarantees the desulfuration efficiency of desulfurizer and the safe and stable operation of system.
Flue gas mist cooling washing system of the present utility model, comprise accident spray equipment, spray pump and water tank, described water tank inner route clapboard is divided into influent side and water outlet side, influent side and water outlet side bottom are interconnected, the inlet of described spray pump is communicated with the water tank water outlet side, and outlet is communicated with the accident spray equipment, and described accident spray equipment is arranged in the gas approach of absorption tower, described absorption tower gas approach bottom transverse is provided with the cleaning solution feeder, and described cleaning solution feeder feeds the water tank water intake side.
Further, be provided with oil drain out with concordant place, dividing plate top on the described water tank;
Further, described water tank bottom is provided with sewage draining exit;
Further, described water tank is provided with manhole door;
Further, described water tank upper is provided with air bleeding valve;
Further, described absorption tower gas approach along flue gas stream to downward-sloping setting, described cleaning solution feeder along flue gas stream to being positioned at accident spray equipment rear side;
Further, described accident spray equipment comprises the shower that is set up in parallel, and is set up in parallel the atomizing spray hole on the shower, and the water jet in described atomizing spray hole and flue gas stream are to identical.
The beneficial effects of the utility model are: the utility model increases a dividing plate in water tank, water tank is divided into influent side and water outlet side, influent side and water outlet side bottom are interconnected, shower water washing greasy dirt is laggard goes into the water tank influent side, greasy dirt swims in the water surface, and water is circulated to the water tank water outlet side from the water tank bottom and is taken away by spray pump and sprays circulation, thereby has avoided greasy dirt to be taken away by spray pump, greasy dirt no longer enters the spray circulation, but at the water tank water intake lateral enrichment; Therefore, the utility model can guarantee the quality of shower water, has guaranteed that system's long-play also has good deoiling effect, has guaranteed the desulfuration efficiency of desulfurizer and the safe and stable operation of system.
