Abstract
A kind of thermal power plant bottom ash overflow water process is cooling and cyclic utilization system, including bottom ash overflow water reception tank, filter, cooling tower, it is characterised in that：Connecting pipe chemical-dosing mixer between bottom ash overflow water reception tank and filter, filter connect intermediate pool, and intermediate pool connects cooling tower, and cooling tower connects water purifying tank, connects a grab bucket crane above bottom ash overflow water reception tank.The utility model organic combination and the cooperation for strengthening auxiliary system remove pearl of floaing in waste water, floating ash, the water temperature of overflow water are effectively reduced, make indices in wastewater effluent that can meet bottom ash system water requirement, reduce bottom ash system industrial water rate of water make-up.Therefore, which, which can be subjected to waste water water fluctuation impact, influences, and efficiently removes the polluter in waste water, water temperature is effectively reduced, pH value is adjusted, devices in system configuration and power output can be adjusted flexibly according to each engineering practice, be conducive to the even running maintenance and management of power plant.
Description
Technical field
The utility model relates to thermal power plant hydraulic slag removal system, more particularly, to a kind of bottom ash overflow water process, cold
But and cyclic utilization system.
Background technique
From 1970s, traditional type hydraulic slag removal system begins to thermal power plant extensive use at home and abroad, and
The country it is optimized in recent years upgrading, produces self-balancing high inclination-angle formula dragveyer technology.The technology is in thermal power generation
The application of factory has faster development, and by the end of the year 2015, the country has put into operation and surpassed in the 300MW ~ 600MW coal unit built
40 are crossed, development is swift and violent.But in actual operation, there are coal quality poor quality, the frequent problem of coal varitation causes the quantity of slag to fluctuate
It is larger, so that dragveyer overflow coolant-temperature gage increases, large effect directly is caused to the operation of bottom ash system, is mainly reflected in bottom ash
Cooling effect is poor, and the water quality inferiority of bottom ash overflow water, evaporated water is big, and overflow circulating water increases and station service increases etc., shadow
The safe and stable operation of unit is rung.
Utility model content
The purpose of this utility model is：External circulation heat exchanging is forced using bottom ash overflow water, water treatment reduces bottom ash overflow
Water temperature, increase slag water temperature end is poor, realizes water-saving, water purification, high efficient heat exchanging, it is made to meet the peace of fired power generating unit hydraulic slag removal system
Full service requirement.
To achieve the above object, the utility model provides that a kind of thermal power plant bottom ash overflow water process is cooling and circulation benefit
With system, including bottom ash overflow water reception tank, filter, cooling tower, it is characterised in that：Bottom ash overflow water reception tank and filter
Between connecting pipe chemical-dosing mixer, filter connect intermediate pool, intermediate pool connect cooling tower, cooling tower connect water purification
Pond, bottom ash overflow water reception tank top connect a grab bucket crane.
The bottom ash overflow water receives top and connects pH value regulating device, avoids pH value fluctuation pair in wastewater treatment process
Equipment, corrosive pipeline.
The utility model organic combination and the cooperation for strengthening auxiliary system remove pearl of floaing in waste water, floating ash, are effectively reduced excessive
The water temperature of flowing water makes indices in wastewater effluent that can meet bottom ash system water requirement, reduces bottom ash system industrial water and mends
Water.Therefore, which, which can be subjected to waste water water fluctuation impact, influences, and efficiently removes the polluter in waste water, effectively
Water temperature is reduced, pH value is adjusted, devices in system configuration and power output can be adjusted flexibly according to each engineering practice, be conducive to
The even running maintenance and management of power plant.The system investments are low, and land occupation is extremely compact, have higher requirements to water resource recycling
Engineering it is more applicable.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
In figure：1, bottom ash overflow water reception tank；2, elevator pump；3, pipeline chemical-dosing mixer；4, filter；5, intermediate water
Pond；6, middle water pump；7, cooling tower；8, water purifying tank；9, reuse water pump；10, grab bucket crane；11, partition；12, pH value is adjusted
Device.
Specific embodiment
Referring to Fig.1, specific embodiment of the present invention includes bottom ash overflow water reception tank 1, elevator pump 2, pipeline dosing
Mixer 3, filter 4, intermediate pool 5, middle water pump 6, cooling tower 7, water purifying tank 8, reuse water pump 9, grab bucket crane 10, bottom
Connecting pipe chemical-dosing mixer 3 between slag overflow water reception tank 1 and filter 4, added drug are coagulant, flocculation aid, mistake
Filter connects intermediate pool 5, and middle water pump 6 is equipped in intermediate pool, and intermediate pool connects cooling tower 7, and cooling tower connects water purification
Pond 8, water purifying tank 8 is interior to be equipped with reuse water pump 9.
The utility model technical process：Bottom ash overflow water initially enters bottom ash overflow water reception tank 1, and bottom ash overflow water receives
Pond is divided into two lattice by flow direction, and 11 height of partition doubles as overflow plate lower than pond deeply.The bottom ash overflow water reception tank can digest
The a large amount of discharge of wastewater of power plant's impact, while slag, the ash content in bottom ash overflow water can be precipitated, to reduce subsequent place
The processing load of reason system.Subsequent filter further carries out the polluters such as particulate matter, pearl of floaing, floating ash, SS in waste water
Processing, meets bottom ash water requirement.In process flow, dosing coagulant, flocculation aid before filter, equal energy intensive filtration device
Treatment effect improves pearl of floaing, floating grey removal rate.Meanwhile bottom ash has higher requirements to water temperature with water, filter water outlet is using setting
The cooling tower on treating stations roof is set, as far as possible reduction cooling tower leaving water temperature, to reduce bottom ash treatment water water to greatest extent
Amount, to reduce the power output of entire bottom ash overflow water treatment system.If bottom ash overflow water needs to adjust pH value, overflow in bottom ash
A pH value regulating device is set above flowing water reception tank, pH value in wastewater treatment process is avoided to fluctuate to equipment, corrosive pipeline.
