When sewage quantity less, while being not continuous blow-down, the dividing plate 41 of cooling tank 21 act as: the high temperature sewage of dividing plate 41 water inlet one sides can be extruded the low-temperature sewage of opposite side (overflow one side) by overfall, high temperature sewage is temporarily stored in cooling tank 21, cooling naturally under lower environment temperature, when having new effluent stream to come, just can again by overflow pipe 7, discharge, make the sewage being discharged by overflow pipe 7 there is lower temperature.
It is impure that heat exchanger 20 is used for the demineralized water of backwashing equipment, and salt concentration is high, and temperature is normal temperature, generally directly enters trench, thereby wasted the lower temperature of backwashing water.
In technical scheme of the present invention, the sewage after softening water station backwash is entered to cooling tank 21 through backwash outlet pipe 27 and soft sewage valve 10, the sewage of discharging with boiler 18 mixes, thereby plays the effect of the temperature that again reduces boiler 18 effluent sewerages.
Adopt technical scheme of the present invention, by heat exchanger, make the water inlet of boiler emission sewage heating boiler; By the water in the flash steam heating water tank of flash tank (preparing to enter the water of boiler), thereby both reduced the temperature of boiler emission sewage, again dual-heated the temperature of boiler feed water, saved the heat energy that boiler needs, kill two birds with one stone.
The pipeline of exhaust stack is often longer, and safety valve is connected with described exhaust stack by diffusing tube connector, can make two equipment of flash tank and cooling tank share a set of exhaust stack, saves equipment investment, simplifies pipe laying, meets emissions requirements.
The dependency structures such as cooling tank internal partition, can make to enter the sewage that in cooling tank, temperature is relatively high can not go out in horse back overflow, but first by having deposited a period of time and extruded through the lower sewage of temperature after cooling naturally of overflow one side, thereby further reduced the temperature of cooling tank institute effluent sewerage.The setting of running water water inlet pipe, running water temperature-sensing valve etc., when can moisturizing large in boiler blow-off amount or that boiler needs less, by introducing running water, force to reduce sewage temperature, thereby absolutely avoid the higher situation of sewage temperature of discharge, avoid the situation that causes emission point environment temperature high.The setting of first, second bypass pipe, is convenient to maintenance or dredging heat exchanger.
