Description
Technical field
The utility model relates to a kind of systems using tail end wastewater in waste and old cooling tower treatment plant of power plant, belong to waste water ring
Protect processing technology field.
Background technique
Currently, the pollution of industrial wastewater has become the stumbling-block of China's economic development, also gives the life of broad masses of the people
It produces and life causes greatly to injure.In most of waste water of the industries such as electric power, coal chemical industry, have corresponding processing method,
But its tail end wastewater, because high salinity, high rigidity, variation water quality be not big, easy to handle, existing processing technique and method also not at
Ripe, the discharge of tail end wastewater still will cause pollution.
In order to reduce contaminated wastewater, now with power plant use using flue evaporation handle tail end wastewater, flue evaporation
Method is compared with existing wastewater processing technology, and have many merits: equipment is simple, can be effective gram without adding chemical agent
Take the shortcomings that existing waste water treatment system equipment is more, investment is big, operating cost is high and equipment repair and maintenance heavy workload；Operation behaviour
Make simply, the pollutant in waste water is discharged with grey form-separating, no sludge treatment problem；It, can be with since waste water is introduced into flue
Smoke moisture is properly increased, to reduce the specific resistance of dust granule in flue gas, is conducive to improve efficiency of dust collection.But flue
There is also obvious shortcomings for evaporation process: the flue before most of built plant dust catchers moves towards complicated, such as uses single-stage
It is spraying, due to the variation in flow field, it is easy to cause to generate dust stratification near flue turn, to influence to discharge fume, or even corrosion cigarette
Road is difficult to meet waste water evaporation requirement.Therefore, in order to overcome the disadvantages mentioned above of flue evaporation, it is necessary to develop adaptable
, the novel waste water evaporating that stability is high and method.
Our factory unit situation is two 350MW and two 135MW water chillers, since recent our factory 135MW unit will be into
The transformation of row optical axis, therefore will have a cooling tower free time and scrap, in view of current wastewater comprehensive treatment working distal tip wastewater treatment
Technology is still without mature technology, therefore we pass through heat required for air self-suction amount to air cooling tower, evaporation and external heat
Source amount is calculated in detail, and 15 ton/hours of tail end wastewater is sprayed by atomising device by the air cooling tower top layer scrapped, is utilized
The aerodynamic design of cooling tower, a large amount of dry airs are entered by air-cooled tower bottom, different by end using the partial pressure of vapor
Waste water is evaporated, if tail portion cigarette all the way is drawn in plan since bottom cooling tower enters lack of air to evaporate whole waste water
Gas or the hot end LGGH water source heat the air of air cooling tower self-priming, to evaporate tail end wastewater.It will be big using this scheme
The big investment and operating cost for saving tail end wastewater processing, and can waste utilization, discarded air cooling tower is fully utilized
Come.
