Description
Technical field
Patent of the present invention relates to Waste water concentrating liquid treating system, particularly relates to a kind of minimum discharge wet-esp Waste water concentrating liquid treating system.
Background technology
At present, for meeting stricter environmental requirement, many coal-burning power plants implement minimum discharge improvement project, set up Wet-type electric dust removal system (hereinafter referred to as wet electricity).Wet electricity needs a large amount of wash-down water, and after this partial flushing water washes away pole plate, flow out from ash bucket, component loops utilizes, and part is outer to be lined up as wet electric waste water.Wet electric waste water is delivered to wet electric high-efficiency clarifier by wet-pit and is recycled.Top clear water after clarification by tube overflow to mist eliminator flushing water tank, and through mist eliminator flushing water pump deliver to desulfuration absorbing tower for absorption tower demisting device cleaning, bottom clarification concentrated solution deliver to desulfuration absorbing tower stock tank for absorption tower moisturizing through sludge pump.Bottom clarification concentrated solution contains more fine dust particles, if for absorption tower moisturizing, certainly will impact the reaction of sweetening agent in absorption tower, easily block filter cloth simultaneously, increase the burden of vacuum belt machine, affect desulphurization system safe operation.Meanwhile, the extra waste water that increases, to desulfuration absorbing tower, caused Heavy Duty to desulfuration absorbing tower water balance.
Summary of the invention
The object of the invention is to overcome prior art deficiency, provide a kind of rational in infrastructure, reduce wet electric Waste water concentrating liquid to the impact of desulphurization system, ensure the wet electric Waste water concentrating liquid treating system of system safety operation.
For achieving the above object, present invention employs following technical scheme:
Minimum discharge wet-esp Waste water concentrating liquid treating system, comprise wet electric high-efficiency clarifier, sludge pump and desulfurization wastewater pond, the Waste water concentrating liquid of wet electric high-efficiency clarifier bottom is connected to desulfurization wastewater pond by sludge pump, wet electric high-efficiency clarifier top overflow is connected to the water-in of mist eliminator water tank, the water outlet of mist eliminator water tank is connected to the mist eliminator of desulfuration absorbing tower by mist eliminator water pump, the gypsum overboard pump of desulfuration absorbing tower is connected to desulfurization wastewater pond by desulfurization wastewater rotational flow station, desulfurization wastewater pond connects desulfurization wastewater three header and desulfurization wastewater settler successively.
The invention has the beneficial effects as follows:
1, good stability, security is high: wet electric Waste water concentrating liquid directly delivers to desulfurization wastewater treatment system, reduces the impact of the reaction on sweetening agent in absorption tower, to prevent in concentrated solution fine particle to the blocking of filter cloth simultaneously, reduce the burden of vacuum belt machine, improve the security of system cloud gray model.
2, prevent desulfuration absorbing tower liquid level too high: after minimum discharge transformation, because of setting up low low temp. electric dedusting, cigarette temperature drop is low causes absorption tower steam output minimizing, and absorption tower water liquid level easily causes too high and overflow.Wet electric Waste water concentrating liquid is directly outer drains into desulfurization wastewater treatment system, reduces absorbing tower liquid-level excess pressure.
3, technical process is simple, investment and O&M cost low: this programme increase only the connecting pipeline of sludge pump and desulfurization wastewater treatment system and related valve etc., and system process is simple.System major equipment, material are conventional products, and be easy to buying, cost of investment is low.Pipeline is simple, and this system can be included in desulphurization system unified management and safeguard, O&M cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Description of reference numerals: wet electric high-efficiency clarifier 1, sludge pump 2, desulfurization wastewater pond 3, desulfurization wastewater three header 4, desulfurization wastewater settler 5, desulfuration absorbing tower 6, desulfurization wastewater rotational flow station 7, mist eliminator water tank 8, mist eliminator water pump 9.
Embodiment
Below in conjunction with embodiment, the present invention is described further.The explanation of following embodiment just understands the present invention for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection domain of the claims in the present invention.
As shown in Figure 1, the minimum discharge wet-esp Waste water concentrating liquid treating system of the present embodiment, comprise wet electric high-efficiency clarifier 1, sludge pump 2 and desulfurization wastewater pond 3, the Waste water concentrating liquid of wet electric high-efficiency clarifier 1 bottom is connected to desulfurization wastewater pond 3 by sludge pump 2, wet electric high-efficiency clarifier 1 top overflow is connected to the water-in of mist eliminator water tank 8, the water outlet of mist eliminator water tank 8 is connected to the mist eliminator of desulfuration absorbing tower 6 by mist eliminator water pump 9, the gypsum overboard pump of desulfuration absorbing tower 6 is connected to desulfurization wastewater pond 3 by desulfurization wastewater rotational flow station 7, desulfurization wastewater pond 3 connects desulfurization wastewater three header 4 and desulfurization wastewater settler 5 successively.
Wet electric Waste water concentrating liquid treating system of the present invention, the bottom Waste water concentrating liquid of wet electric high-efficiency clarifier 1 delivers to desulfurization wastewater pond 3 by sludge pump 2, the waste water of discharging with desulfuration absorbing tower 6 mixes, outer row is processed through desulfurization wastewater three header 4, desulfurization wastewater settler 5, thus reduce Waste water concentrating liquid to the impact of desulphurization system, ensure system safety operation.
