Description

Minimum discharge wet-esp Waste water concentrating liquid treating system
Technical field
This utility model patent 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 tightened up environmental requirement, many coal-burning power plants implement minimum discharge improvement project, set up Wet-type electric dust removal system (the wettest electricity).Wet electricity needs a large amount of flushing waters, after this partial flushing water washes away pole plate, flows out from ash bucket, and part recycles, and part is outer to be lined up as wet electricity waste water.Wet electricity waste water is delivered to wet electricity high-efficiency clarifier by draining pump 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 clean, 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 desulfurizing agent in absorption tower, easily blocks filter cloth simultaneously, increases the burden of vacuum belt machine, affect desulphurization system safe operation.Meanwhile, desulfuration absorbing tower water balance, to desulfuration absorbing tower, was caused HD by the extra waste water that increases.
Utility model content
The purpose of this utility model is to overcome prior art not enough, it is provided that a kind of rational in infrastructure, reduces the Waste water concentrating liquid impact on desulphurization system of wet electricity, it is ensured that the wet electricity Waste water concentrating liquid treating system of system safety operation.
For achieving the above object, this utility model have employed techniques below scheme:
Minimum discharge wet-esp Waste water concentrating liquid treating system, including wet electricity high-efficiency clarifier, sludge pump and desulfurization wastewater pond, the Waste water concentrating liquid of wet electricity high-efficiency clarifier bottom is connected to desulfurization wastewater pond by sludge pump, the high-efficiency clarifier top overflow of wet electricity is connected to the water inlet of demister water tank, the outlet of demister water tank is connected to the demister of desulfuration absorbing tower by demister water pump, the Gypsum Fibrosum excavationg pump of desulfuration absorbing tower is connected to desulfurization wastewater pond by desulfurization wastewater rotational flow station, and desulfurization wastewater pond is sequentially connected with desulfurization wastewater three header and desulfurization wastewater defecator.
The beneficial effects of the utility model are:
1, good stability, safety is high: wet electricity Waste water concentrating liquid is fed directly to desulfurization wastewater treatment system, reduces the impact of the reaction of desulfurizing agent in absorption tower, prevents the fine particle blocking to filter cloth in concentrated solution simultaneously, reduce the burden of vacuum belt machine, improve the safety that system is run.
2, preventing desulfuration absorbing tower liquid level too high: after minimum discharge transformation, because of setting up low temp. electric dedusting, cigarette temperature drop is low causes absorption tower evaporation capacity minimizing, and absorption tower water liquid level easily causes too high and overflow.Wet electricity Waste water concentrating liquid is directly outer drains into desulfurization wastewater treatment system, reduces absorbing tower liquid-level excess pressure.
3, technological process is simple, and investment and O&M cost are low: this programme increase only sludge pump and the connecting line of desulfurization wastewater treatment system and related valve etc., and system process is simple.System capital equipment, material are conventional products, it is easy to buying, cost of investment is low.Pipeline is simple, this system can be included in desulphurization system unified management and safeguard, O&M cost is low.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation;
Description of reference numerals: wet electricity high-efficiency clarifier 1, sludge pump 2, desulfurization wastewater pond 3, desulfurization wastewater three header 4, desulfurization wastewater defecator 5, desulfuration absorbing tower 6, desulfurization wastewater rotational flow station 7, demister water tank 8, demister water pump 9.
Detailed description of the invention
Below in conjunction with embodiment, this utility model is described further.The explanation of following embodiment is only intended to help and understands this utility model.Should be understood that; for those skilled in the art; on the premise of without departing from this utility model principle, it is also possible to this utility model is carried out some improvement and modification, these improve and modification also falls in this utility model scope of the claims.
As shown in Figure 1, the minimum discharge wet-esp Waste water concentrating liquid treating system of the present embodiment, including wet electricity high-efficiency clarifier 1, sludge pump 2 and desulfurization wastewater pond 3, the Waste water concentrating liquid of wet electricity high-efficiency clarifier 1 bottom is connected to desulfurization wastewater pond 3 by sludge pump 2, the high-efficiency clarifier 1 top overflow of wet electricity is connected to the water inlet of demister water tank 8, the outlet of demister water tank 8 is connected to the demister of desulfuration absorbing tower 6 by demister water pump 9, the Gypsum Fibrosum excavationg pump of desulfuration absorbing tower 6 is connected to desulfurization wastewater pond 3 by desulfurization wastewater rotational flow station 7, desulfurization wastewater pond 3 is sequentially connected with desulfurization wastewater three header 4 and desulfurization wastewater defecator 5.
Wet electricity Waste water concentrating liquid treating system of the present utility model, the bottom Waste water concentrating liquid of wet electricity high-efficiency clarifier 1 delivers to desulfurization wastewater pond 3 by sludge pump 2, the waste water discharged with desulfuration absorbing tower 6 mixes, outer row is processed through desulfurization wastewater three header 4, desulfurization wastewater defecator 5, thus reduce the impact on desulphurization system of the Waste water concentrating liquid, it is ensured that system safety operation.
