Description
Technical field
The present invention relates to a kind of waste-heat recovery device, particularly a kind of waste heat recovery device with water-source heat pump reclaiming waste water residual heat.
Background technology
As everyone knows, mainly coal-burning boiler, gas fired-boiler, electric boiler or solar water heater that domestic at present bathing place and barber shop's water intaking preheating adopt.There is environmental pollution and the large shortcoming of floor space in coal-burning boiler; There is the problem of safety requirements height and source of the gas supply in gas fired-boiler; Electric boiler uses high-grade electric energy to heat, and energy quality is a kind of waste, and cost is high; Solar water heater use cost is cheap, but initial stage input cost is large, and floor space is wide, and exists by the large defect of weather effect.In addition, the hot water amount of bathing place and barber shop is large, and the temperature of waste water after having a bath and having one's hair wash is high, and heat is large, and as direct discharge, cause the significant wastage of the energy, and the discharge of hot water also causing impact to environment, is again a kind of environmental pollution.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of rational in infrastructure, abundant recovery waste water heat, and having the waste heat recovery device with water-source heat pump of very high heating efficiency.
The technical solution used in the present invention is: comprise main frame, heat preservation hot water tank, insulation waste water tank, plate type heat exchanger and circulating pump, described main frame comprises compressor, evaporimeter, condenser and choke valve; Described insulation waste water tank is by plate type heat exchanger primary side, circulating pump and evaporimeter primary side inlet communication, and the outlet of evaporimeter primary side is communicated with sewage network; Described evaporimeter secondary side import is by choke valve and condenser primary side outlet, and the outlet of evaporimeter secondary side is by compressor and condenser primary side inlet communication; The import of described condenser secondary side is communicated with outside tap water supply net by plate exchanger secondary side, and described condenser secondary side outlet is communicated with heat preservation hot water tank, and heat preservation hot water tank outlet is communicated with hot water user.
In above-mentioned waste heat recovery device with water-source heat pump, described heat preservation hot water tank second outlet is on the pipeline of circulating pump and evaporimeter primary side inlet communication; The outlet of this heat preservation hot water tank second is provided with thermostatic valve with the pipeline that circulating pump is connected with the pipeline of evaporimeter primary side inlet communication.
The invention has the beneficial effects as follows: waste water and running water are carried out first time exchange heat by plate type heat exchanger of the present invention, to the running water preheating that will enter condenser secondary side; In main frame of the present invention, after condenser primary side cold-producing medium enters evaporimeter secondary side, carry out heat exchange with the waste water of evaporimeter primary side; In evaporimeter, after the part of waste heat that refrigerant suction waste water carries, be vaporizated into liquid equality of temperature with the gaseous state of pressing by liquid state; Cold-producing medium temperature and pressure after compressor compresses of gaseous state raise further, and the running water that the gaseous refrigerant through overcompression enters the preheating of condenser primary side and condenser secondary side carries out heat exchange; Through the running water of heat exchange after flow-dividing control, enter hot water user.As can be seen here, the present invention fully can extract the waste heat in waste water, and the waste heat of extraction is used for hot water user to utilize further, therefore the present invention has thermal loss is little, energy utilization rate is higher feature.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, the present invention includes main frame 1, heat preservation hot water tank 2, insulation waste water tank 4, plate type heat exchanger 5 and circulating pump 6, described main frame 1 comprises compressor 12, evaporimeter 13, condenser 11 and choke valve 15; Described insulation waste water tank 4 is by plate type heat exchanger 5 primary side, circulating pump 6 and evaporimeter 13 primary side inlet communication, and the outlet of evaporimeter 13 primary side is communicated with sewage network; Described evaporimeter 13 secondary side import is by choke valve 15 and condenser 11 primary side outlet, and the secondary side outlet of evaporimeter 13 is by compressor 12 and condenser 11 primary side inlet communication; The import of described condenser 11 secondary side is communicated with outside tap water supply net by plate type heat exchanger 5 secondary side, and described condenser 11 secondary side outlet is communicated with heat preservation hot water tank 2, and heat preservation hot water tank 2 outlet is communicated with hot water user 3.Second outlet of described heat preservation hot water tank 2 is on the pipeline 14 of circulating pump 6 with the primary side inlet communication of evaporimeter 13; The outlet of this heat preservation hot water tank 2 second is provided with thermostatic valve 7 with the pipeline 21 that circulating pump 6 is connected with the pipeline 14 of the primary side inlet communication of evaporimeter 13.
During use, ON cycle pump 6, make to be incubated the waste water collected in waste water tank 4 and move towards main frame 1, and also move towards main frame 1 from the new water of tap water supply net, when new water and waste water flows through plate type heat exchanger 5, waste water carries out preheating to new water.After flowing to main frame 1, after the cold-producing medium of condenser 11 primary side enters evaporimeter 13 secondary side, carry out heat exchange with the waste water of evaporimeter 13 primary side; In evaporimeter 13, after the part of waste heat that refrigerant suction waste water carries, be vaporizated into liquid equality of temperature with the gaseous state of pressing by liquid state; The cold-producing medium of gaseous state is after compressor 12 compresses, and temperature and pressure raise further, and the new water that the gaseous refrigerant through overcompression enters the preheating of condenser 11 primary side and condenser 11 secondary side carries out heat exchange; Through the new water of heat exchange after heat preservation hot water tank 2 flow-dividing control, enter hot water user 3.When crossing cold to prevent weather, evaporimeter 13 is caused to freeze, second outlet of pipeline 14 and heat preservation hot water tank 2, controlled by thermostatic valve 7, when temperature is lower than certain value, pipeline 14 is open-minded with the pipeline 21 of the second outlet of heat preservation hot water tank 2, and the device 13 that avoids evaporating freezes to cause the present invention can not use in cold weather.As can be seen here, the present invention can extract the waste heat in waste water fully, and the waste heat of extraction is used for hot water user to utilize further, therefore the present invention has thermal loss is little, energy utilization rate is higher feature.
