Summary of the invention
The object of the invention is to overcome deficiency of the prior art, provide a kind of rational in infrastructure, reduce contaminated wastewater, reduce the wet electric waste water reuse system of water consumption.
This wet electric waste water reuse system, comprises draining pump, high-efficiency clarifier, mist eliminator flushing water tank, mist eliminator flushing water pump, wet desulphurization absorption tower and sludge pump; Draining pump is connected with the import of high-efficiency clarifier, the top delivery port of high-efficiency clarifier is connected with the import of mist eliminator flushing water tank, mud mouth bottom high-efficiency clarifier is connected to stock tank place, bottom, absorption tower by sludge pump, and the delivery port of mist eliminator flushing water tank is connected to the spray piping interface of top, absorption tower demister by mist eliminator flushing water pump.
As preferably: the water inlet of mist eliminator flushing water tank is also connected with fresh water (FW) water pipe.
As preferably: high-efficiency clarifier comprises core barrel, mud scraper and filler from top to bottom successively and is all located in housing.
The invention has the beneficial effects as follows:
1, reduce contaminated wastewater, reduce water consumption
Wet electric waste water reuse system processes wet electric waste water, water after clarification is reclaimed as absorption tower demisting device flushing water simultaneously and use, the bottom concentrate of high-efficiency clarifier reclaims as absorption tower supplementing water and uses, and decreases discharge of wastewater and pollutes, and effectively reduces the water consumption of system.
2, adaptability and good stability
High-efficiency clarifier still can carry out Separation of Solid and Liquid effectively when wet electric waste water suspension change in concentration is larger, and can dual-purpose one standby or mode for subsequent use each other reasonably configure, and ensures clarifier stable operation; The fresh water (FW) water pipe of mist eliminator flushing water tank can ensure the water yield and the water quality requirement of absorption tower demisting device flushing water.When whole system tackles changeable operating mode, adaptability is good, reliable and stable.
3, technological process is simple, investment and O&M cost low
Wet electric waste water reuse system increase only high-efficiency clarifier, mist eliminator flushing water tank, mist eliminator flushing water pump, sludge pump and connecting line etc., and system process is simple.System capital equipment, material are conventional products, and be easy to buying, cost of investment is low.High-efficiency clarifier power is not more than 3kW, and energy consumption is lower, and system equipment is few, and pipeline is simple, and this system can be included in desulphurization system unified management and safeguard, O&M cost is low.

Description of reference numerals: draining pump 1, high-efficiency clarifier 2, mist eliminator flushing water tank 3, mist eliminator flushing water pump 4, absorption tower 5, sludge pump 6, housing 7, core barrel 8, mud scraper 9, filler 10.
Detailed description of the invention
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 to Figure 2.This wet electric waste water reuse system of the present invention, comprises draining pump 1, high-efficiency clarifier 2, mist eliminator flushing water tank 3, mist eliminator flushing water pump 4, wet desulphurization absorption tower 5 and sludge pump 6; Draining pump 1 is connected with the import of high-efficiency clarifier 2, and high-efficiency clarifier 2 comprises core barrel 8, mud scraper 9 and filler 10 from top to bottom successively and is all located in housing 7.The top delivery port of high-efficiency clarifier 2 is connected with the import of mist eliminator flushing water tank 3, and the water inlet of mist eliminator flushing water tank 3 is also connected with fresh water (FW) water pipe.Mud mouth bottom high-efficiency clarifier 2 is connected to stock tank place, bottom, absorption tower 5 by sludge pump 6, and the delivery port of mist eliminator flushing water tank 3 is connected to the spray piping interface of top, absorption tower 5 demister by mist eliminator flushing water pump 4.
Wet electric waste water reuse system is made up of parts such as wet electric Waste Water Treatment, waste water recycling system and system water supplements.
(1) wet electric Waste Water Treatment
Wet electric waste water delivers to high-efficiency clarifier 2 by the electric draining pump 1 that wets, and relies on physics settlement action to carry out Separation of Solid and Liquid in high-efficiency clarifier 2.After Separation of Solid and Liquid, high-efficiency clarifier 2 top clear water suspension content is less than 500mg/L.
(2) waste water recycling system
High-efficiency clarifier 2 top clean water overflow, to mist eliminator flushing water tank 3, delivers to desulfuration absorbing tower 5 as the reuse of absorption tower demisting device flushing water through mist eliminator flushing water pump 4.The bottom concentrate of high-efficiency clarifier 2 is then disposed to absorption tower 5 stock tank by sludge pump 6 and carries out reuse as absorption tower 5 moisturizing.
(3) system water supplement
Because the water yield of mist eliminator flushing water is comparatively large and higher to water quality requirement, therefore draws a road fresh water (FW) water pipe to mist eliminator flushing water tank 3, meet absorption tower demisting device to the water yield of flushing water and water quality requirement.
Wet electric waste water clarifying effect is good, water inlet concentration of suspension is more than 3000mg/L, clarification upper back clear water concentration of suspension is not more than 300mg/L, desulphurization system normal operation simultaneously, Parameters variation is steady, and water-saving result is obvious, for separate unit 1000MW unit, compared with all arranging outward with wet electric waste water, adopt this system can reduce contaminated wastewater amount and be about 39m
3/ h.
During system cloud gray model, wet electric draining pump is connected with high-efficiency clarifier by pipeline, wet electric waste water is delivered to high-efficiency clarifier and recycles.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 concentrate deliver to desulfuration absorbing tower stock tank for absorption tower moisturizing through sludge pump.
