Description
Technical field
The utility model relates to a kind of water treatment system, especially a kind of using the system of municipal middle water as circulating cooling water of power plant make up water.
Background technology
Along with industrial expansion, industrial water consumption sharply increases, and make up water many employings underground water of the recirculated water of the current newly-built fuel-burning power plant of part and mostly built old power plant or surface fresh water, therefore optimize the utilization of water resources, further exploitation reducig underground water and surface fresh water become the problem of our research.
Summary of the invention
For the weak point existed in the problems referred to above, the utility model provides a kind of using municipal middle water as water source, is optimized process to it, using as circulating cooling water of power plant make up water by the system of municipal middle water as circulating cooling water of power plant make up water.
For achieving the above object, the utility model provides a kind of using the system of municipal middle water as circulating cooling water of power plant make up water, comprise the former pond (1) be communicated with successively, settling pond (2), pulling flow type chlorine contact ditch (3), become hole filtering pool (4) and clean water basin (5), the input terminus of described settling pond (2) is connected with coagulating agent injection device (7), the input terminus of described pulling flow type chlorine contact ditch (3) is connected with sterilant injection device (9) with sulfuric acid injection device (8) respectively, the injection side of described former pond (1) is connected with city B-grade sewage hydraulic pipe, the output terminal of described clean water basin (5) is connected with recirculated cooling water make-up system.
Above-mentioned using the system of municipal middle water as circulating cooling water of power plant make up water, wherein, described coagulating agent injection device (7) injects the milk of lime of the carbonate hardness for removing B-grade sewage in described settling pond (2).
Above-mentioned using the system of municipal middle water as circulating cooling water of power plant make up water, wherein, in described former pond (1), be provided with the water quality detecting device for detecting the water quality of the city B-grade sewage injected therein.
Above-mentioned using the system of municipal middle water as circulating cooling water of power plant make up water, wherein, the output terminal of described former pond (1) is also connected by the injection side of switch valve (6) with described clean water basin (5).
Compared with prior art, the utility model has the following advantages:
The utility model can make full use of city B-grade sewage, water source is it can be used as to be optimized process, using as circulating cooling water of power plant make up water water source, the use of exploitation to underground water and surface fresh water can be reduced further, to realize the object of fresh-water-saving resource;
Using milk of lime as being used for the main coagulating agent removing the carbonate hardness in B-grade sewage, there is low price, be easy to the advantage that obtains;
Adopt city B-grade sewage as water source, its price, well below water source of fresh water, can reduce the running cost of power plant.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
Main Reference Numerals is described as follows:
1-former pond 2-settling pond
3-pulling flow type chlorine contact ditch 4-becomes hole filtering pool
5-clean water basin 6-switch valve
7-coagulating agent injection device 8-sulfuric acid injection device
9-sterilant injection device 10-recirculated cooling water make-up system
Embodiment
As shown in Figure 1, the utility model provides a kind of using the system of municipal middle water as circulating cooling water of power plant make up water, comprise be communicated with successively former pond 1, settling pond 2, pulling flow type chlorine contact ditch 3, become hole filtering pool 4 and clean water basin 5, mechanical accelerating purifying pool selected by settling pond 2.Wherein, the output terminal of city B-grade sewage hydraulic pipe is connected with the injection side in former pond 1, the output terminal in former pond 1 is connected by the injection side of raw water pump with settling pond 2, and the output terminal of clean water basin 5 is connected with recirculated cooling water make-up system 10 by fresh water pump.
The input terminus of settling pond 2 is connected with coagulating agent injection device 7, and wherein, the coagulating agent that coagulating agent injection device injects in settling pond is other coagulating agent such as milk of lime or bodied ferric sulfate, by milk of lime to remove the carbonate hardness in B-grade sewage.
Pulling flow type chlorine contact ditch 3 input terminus be connected with sterilant injection device 9 with sulfuric acid injection device 8 respectively, by inject sulfuric acid adjust the pH value of water quality, by injection sterilant to carry out sterilization to water quality.
In addition, in former pond 1, be provided with the water quality detecting device for detecting the water quality of the city B-grade sewage injected therein, the output terminal in former pond 1 is also connected by the injection side of switch valve 6 with clean water basin 5.If the water quality being filled to the city B-grade sewage in former pond can reach the requirement of water coolant water, then without the need to processing city B-grade sewage, can be directly injected in clean water basin by switch valve.
Operationally, city B-grade sewage injects former pond by hydraulic pipe to the utility model; Through raw water pump, city B-grade sewage is injected settling pond, and add coagulating agent in settling pond; Water quality after clarification enters pulling flow type chlorine contact ditch, and adds sulfuric acid and sterilant at the same time, thus the pH value of regulating water quality, and sterilization is carried out to water quality; Water quality after process enters clean water basin after variable orifice gap filter, then delivers in recirculated cooling water water charging system through fresh water pump.
In addition, when city B-grade sewage water quality can reach the requirement of water coolant water, former pond directly enters recirculated cooling water water charging system by bypass conduit.
The foregoing is only preferred embodiment of the present utility model, is only illustrative for invention, and nonrestrictive.Those skilled in the art is understood, and can carry out many changes in the spirit and scope that invention claim limits to it, amendment, even equivalence, but all will fall in protection domain of the present utility model.
