As shown in Figure 1, this utility model waste water residual heat recovery source pump is made up of boiler 1, heat pump 2, waste water sump 3, waste water storage bin 4, preheating heat exchanger 5, hot water circulating pump 6, waste water preheating immersible pump 7, waste water circulating pump 8, magnetic valve 9, magnetic valve 10, magnetic valve 11, check-valves 12, filter 13 etc.
Heat pump contains: air-cooled evaporimeter 14, water-cooled evaporimeter 15, condenser 16, on a pipe for flowing of refrigerant road between air-cooled evaporimeter 14 and the condenser 16, be provided with compressor 17, be provided with choke valve 18 on another pipe for flowing of refrigerant road between water-cooled evaporimeter 15 and the condenser 16, air-cooled evaporimeter 14 is connected with water-cooled evaporimeter 15 heat-releasing pipeline two ends.Also have bathing place 19, running water 20, sewer 21, water level controller 22, water level controller 23, water level controller 24, boiler temperaturecontrol sensor 25, waste water temperature at discharging condensate control sensor 26, bilge well 27 among the figure.
Running water 20 outlets divide two-way, and one road running water is just controlled according to the boiler water level by magnetic valve 9 and entered preheating heat exchanger 5, enters 16 heat exchange of source pump condenser then, enters in the boiler 1 again; One road cold water is for bathing place 19.
The water inlet pipe of boiler 1 connects source pump condenser 16 delivery ports, and the hot water of generation enters boiler.1 goes out moisture two-way one road hot water enters source pump condenser 16 water inlets, and one road hot water is for bathing place 19.
Robot control system(RCS) adopts the interior water level control of hot water temperature T1, the T2 control of waste water temperature at discharging condensate and boiler, waste water storage bin and the waste water sump in the boiler, and the water level control line as shown in Figure 2.Wherein boiler water level controller 22 comprises four control line V1, V2, V3 and V4, and waste water storage bin water level controller 23 comprises two control line V5 and V6, and waste water sump water level controller 24 comprises two control line V7 and V8.
The course of work of this utility model is:
One, under the situation of no waste water supply:
When bringing into operation, do not have waste water in the waste water storage bin, valve magnetic valve 9, magnetic valve 10 are opened at this moment, and magnetic valve 11 cuts out; Heat pump cuts out; Waste water preheating immersible pump, waste water circulating pump, hot water circulating pump are closed; Water level in boiler reaches V3, and hot water circulating pump is opened; When T1 is lower than 5 ℃ of design temperatures (40～50 ℃), heat pump compressor and air-cooled evaporator fan are opened, and when T1 reaches design temperature (45～55 ℃), heat pump compressor and air-cooled evaporator fan are closed.When water level reaches V1, magnetic valve 9 cuts out.
Two, under the situation that the waste water supply is arranged:
After using a period of time, water level is higher than V7 in the waste water sump, opens waste water preheating immersible pump, waste water enters preheating heat exchanger, enter heat pump water-cooled evaporimeter then and get back in the waste water storage bin, water level reaches V5 in the waste water storage bin, opens the waste water circulating pump and closes air-cooled evaporator fan simultaneously.Turn off magnetic valve 10 when heat pump water-cooled evaporimeter delivery port wastewater temperature T2 drops to design temperature (minimum 5 ℃), open magnetic valve 11 simultaneously, waste water enters bilge well.Water level is lower than V8 in the waste water sump, closes waste water preheating immersible pump.
If in the process of using, the output of waste water is more than the water consumption of heat pump water-cooled evaporimeter, and the water level in the waste water storage bin can rise, and when water level reaches waste water storage bin overflow pipe, waste water overflows in the bilge well by overflow pipe.
If the output of waste water is less than the water consumption of heat pump water-cooled evaporimeter, water level will descend, and reaches V6 and closes the waste water circulating pump and open air-cooled evaporator fan.
In the use, the confluent of running water should satisfy the requirement of bathing water amount, should be equipped with the cold water storage tank when the confluent of running water can not satisfy requiring of bathing water amount.When the bathing water amount was fewer, the water level in the boiler can rise gradually, and when water level reached V1, magnetic valve 9 cut out; Water level can descend in the thereafter heat water tank, and when water level was reduced to V2, magnetic valve 9 was opened, and running water continues moisturizing.
Heat pump water-cooled evaporimeter delivery port wastewater temperature T2 should set according to the outside air temperature situation, when outside air temperature greater than 25 ℃, wastewater temperature T2 is made as 20 ℃; When outside air temperature greater than 15 ℃, wastewater temperature T2 is made as 10 ℃; When outside air temperature is lower than 15 ℃, wastewater temperature T2 is made as 5 ℃.
In order to prevent that duty from frequently switching, between V1 and the V2, between V3 and the V4, between V5 and the V6 and V7 and V8 need establish a certain amount of buffer area.Area size is decided on the fluctuation situation of bathing water amount.
Obviously, this waste water residual heat reclaims waste heat that source pump also can be used for other industry and civilian similar waste water and reclaims.
