Description
Technical field
The present invention relates to a kind of waste-heat recovery device, particularly a kind of water resource heat pump waste-heat recovery device that reclaims waste water residual heat.
Background technology
What as everyone knows, domestic bathing place and barber shop's water intaking preheating at present adopted mainly is coal-burning boiler, gas fired-boiler, electric boiler or solar water heater.Coal-burning boiler exists environmental pollution and the big shortcoming of floor space; There is the problem that safety requirements is high and source of the gas is supplied in gas fired-boiler; Electric boiler uses high-grade electric energy to heat, and is a kind of waste in energy quality, and the cost height; The solar water heater use cost is cheap, but the initial stage input cost is big, and floor space is wide, and existence is subjected to the big defective of weather effect.In addition, the hot water amount that bathing place and barber shop use is big, and the temperature height of the waste water after having a bath and having one's hair wash, heat is big, as direct discharging, causes the significant wastage of the energy, and the discharging of hot water has also caused influence 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, fully reclaim the waste water heat, and the water resource heat pump waste-heat recovery device of very high heating efficiency is arranged.
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 communicated with the import of evaporimeter primary side by plate type heat exchanger primary side, circulating pump, and the outlet of evaporimeter primary side is communicated with sewage network; The import of described evaporimeter secondary side is communicated with the outlet of condenser primary side by choke valve, and the outlet of evaporimeter secondary side is communicated with the import of condenser primary side by compressor; 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 the heat preservation hot water tank, and the outlet of heat preservation hot water tank is communicated with the hot water user.
In the above-mentioned water resource heat pump waste-heat recovery device, second outlet of described heat preservation hot water tank is communicated with on circulating pump and pipeline that the import of evaporimeter primary side is communicated with; This heat preservation hot water tank second outlet is provided with thermostatic valve with the pipeline that the pipeline that circulating pump and the import of evaporimeter primary side are communicated with is connected.
The invention has the beneficial effects as follows: plate type heat exchanger of the present invention carries out the exchange heat first time with waste water and running water, to entering the running water preheating of condenser secondary side; In main frame of the present invention, after condenser primary side cold-producing medium enters the evaporimeter secondary side, carry out heat exchange with the waste water of evaporimeter primary side; In evaporimeter, after the part of waste heat that cold-producing medium absorption waste water carries, by the gaseous state that liquid state is vaporizated into and liquid equality of temperature is pressed together; The cold-producing medium of gaseous state further raises through temperature after the compressor compresses and pressure, and the running water that enters the preheating of condenser primary side and condenser secondary side through the gaseous refrigerant of overcompression carries out heat exchange; After the running water process flow-dividing control through heat exchange, enter the hot water user.This shows that the present invention can fully extract the waste heat in the waste water, and the waste heat that extracts is used for the hot water user with further utilization, so the present invention has the advantages that thermal loss is little, energy utilization rate is higher.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
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 communicated with evaporimeter 13 primary side imports by plate type heat exchanger 5 primary sides, circulating pump 6, and the outlet of evaporimeter 13 primary sides is communicated with sewage network; Described evaporimeter 13 secondary side imports are communicated with the outlet of condenser 11 primary sides by choke valve 15, and the secondary side outlet of evaporimeter 13 is communicated with condenser 11 primary side imports by compressor 12; Described condenser 11 secondary side imports are communicated with outside tap water supply net by plate type heat exchanger 5 secondary sides, and described condenser 11 secondary sides outlet is communicated with heat preservation hot water tank 2, and 2 outlets of heat preservation hot water tank are communicated with hot water user 3.Second outlet of described heat preservation hot water tank 2 is communicated with on circulating pump 6 and pipeline 14 that the primary side import of evaporimeter 13 is communicated with; These heat preservation hot water tank 2 second outlets are provided with thermostatic valve 7 with the pipeline 21 that the pipeline 14 that circulating pump 6 and the primary side import of evaporimeter 13 are communicated with is connected.
During use, ON cycle pump 6 makes the waste water of collecting in the insulation waste water tank 4 towards main frame 1 motion, and from the new water of tap water supply net also towards main frame 1 motion, when new water and waste water were flowed through plate type heat exchanger 5, waste water carried out preheating to new water.After flowing to main frame 1, after the cold-producing medium of condenser 11 primary sides enters evaporimeter 13 secondary sides, carry out heat exchange with the waste water of evaporimeter 13 primary sides; In evaporimeter 13, after the part of waste heat that cold-producing medium absorption waste water carries, by the gaseous state that liquid state is vaporizated into and liquid equality of temperature is pressed together; The cold-producing medium of gaseous state through compressor 12 compressions after, temperature and pressure further raise, the new water that enters the preheating of condenser 11 primary sides and condenser 11 secondary sides through the gaseous refrigerant of overcompression carries out heat exchange; After new water process heat preservation hot water tank 2 flow-dividing control through heat exchange, enter hot water user 3.Cross when cold in order to prevent weather, cause evaporimeter 13 to freeze, pipeline 14 is communicated with second outlet of heat preservation hot water tank 2, by thermostatic valve 7 controls, when temperature is lower than certain value, pipeline 14 is open-minded with the pipeline 21 that second outlet of heat preservation hot water tank 2 is communicated with, and the device 13 that avoids evaporating freezes to cause the present invention can not use in cold weather.This shows that the present invention can extract the waste heat in the waste water fully, and the waste heat that extracts is used for the hot water user with further utilization, so the present invention has the advantages that thermal loss is little, energy utilization rate is higher.
