The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
As shown in drawings, this recycling shower waste water residual heat heating bath hot water device comprises: the insulation hair is assembled pond 1, insulation wastewater collection pond 2, the waste water pump 3 of VFC, dirt separator 4, prime wastewater heat exchange device 5, prime wastewater heat exchange device 6, back level wastewater heat exchange device 7, back level wastewater heat exchange device 8, waste water inspection shaft 9, concurrent heating electric boiler 10, prime measure and control device 11, reservoir 12 in the insulation high position, back level measure and control device 13, heat cycles pump 14, heat pump condenser heater 15, high-order bathing water tank 16, shower circulating pump 17, concurrent heating circulating pump 18, intermediary's water-circulating pump 19, intermediary's water-circulating pump 20, air-conditioning circulating pump 21, the prime heat exchanger of this instance graph, back level heat exchanger and source pump are all by 2 configurations, in the actual engineering, back level heat exchanger and source pump are generally by 3 to 4 configurations.
Recycle that shower waste water residual heat heating bath hot water device is divided into that wastewater heat exchange, running water just heat, middle warm water heats again, bath hot water concurrent heating, five flow processs of intermediary's water circulation:
(1), wastewater heat exchange flow process: the bath wastewater temperature of being discharged by bathhouse is greatly about about 35 ℃, enter the insulation hair through the insulation drainage system and assemble pond 1, in hair is assembled the pond, exclude hair and some and enter insulation wastewater collection pond 2 along utilidor after than bigger material, there is certain water storage capacity in insulation wastewater collection pond, can store waste water greater than the device processes ability in the phase at water use peak.Waste water is forced to extrude by the VFC waste water pump 3 that is positioned at wastewater collection pond 2, along being incubated the waste pipe sequential flow through dirt separator 4, prime wastewater heat exchange device 5, prime wastewater heat exchange device 6, back level wastewater heat exchange device 7, be discharged to waste water inspection shaft 9 behind the back level wastewater heat exchange device 8, wherein dirt separator 4 is that bath wastewater is done further thin the filtration, bath wastewater is in prime wastewater heat exchange device 5 and prime wastewater heat exchange device 6, carry out direct heat transfer with reflux type and low temperature running water with 1: 1 flow proportional, its temperature is reduced to 25 ℃ after the heat exchange, in back level wastewater heat exchange device 7 and back level wastewater heat exchange device 8, carry out heat exchange subsequently with reflux type and intermediary's water, the low temperature intermediary water that is provided by the evaporimeter of source pump offers remaining waste heat in the bath wastewater evaporimeter of source pump in a looping fashion, guarantees the normal operation of source pump.Through after the level heat exchange, water temperature is reduced to the bath wastewater below 10 ℃, enters municipal sewage pipe network through waste water inspection shaft 9.
