Combine accompanying drawing and embodiment that the utility model is done further explain at present.
The specific embodiment
Shown in accompanying drawing 1; The described washing emporium of the utility model utilizes source pump to carry out the system of Waste Heat Recovery; Comprise water source heat pump units 1, water resource heat pump sewage side water pump 2, sewage heat exchanger 3, sewage (waste water) recirculating pump 4, water resource heat pump circulating pump 5, cesspool 6, attemperater 7, air energy heat pump circulating pump 8, air energy heat pump unit 9, and the steam boiler 15 relevant with producing sewage or used heat, boiler smoke waste heat recovery heat exchanger 16, laundry unit 12, laundry unit heat supply water water pump 11, oven dry unit 13, oven dry unit discharge duct 10 and ironing equipment 14.
Wherein, air energy heat pump unit 9 be positioned over oven dry unit discharge duct 10 exhaust position or near so that the heat in the absorbing waste gas.
The laundry sewage that laundry unit 12 is discharged at first gets into cesspool 6, drains after the heat in the sewage is absorbed again and carries out sewage disposal.
The high-temperature steam that steam boiler 15 comes out is used in three places, that is: laundry unit 12, oven dry unit 13 and ironing equipment 14.
The system that a whole set of washing emporium utilizes source pump to carry out Waste Heat Recovery comprises three little recuperation of heat subsystems: (1) steam boiler fume waste heat recovery system.Through boiler smoke waste heat recovery heat exchanger 16 of installing on the flue of steam boiler 15, with the cold water heating (generally can be heated to 70 ℃-80 ℃) that gets into heat exchanger, the hot water after being heated is used for steam boiler is carried out moisturizing.Compare the direct mode of mending steam boiler 15 of original cold water and can practice thrift a large amount of fuel costs.
(2) oven dry unit exhaust waste heat recovery system.Oven dry unit 13 duration of works continue to discharge quantity of waste heat, and this hot air temperature generally can reach 40～50 ℃.Can the used heat in the hot gas be recycled through being installed near oven dry unit discharge duct 10 air energy heat pump units 9, come the water in the heat tracing water tank.Hot water in the attemperater can be delivered in the laundry unit 12 through laundry unit heat supply water water pump 11 and use.Compared originally cold water is directly sent into laundry unit 12, the mode that heats with Boiler Steam then also can be practiced thrift a large amount of boiler oils.
(3) laundry sewage WHRS: laundry unit 12 can be discharged large amount of sewage in the link of high temperature cleaning and cold rinse, and the temperature of these sewage generally can reach more than 30 ℃.Used heat in this sewage can adopt water source heat pump units 1 to reclaim.In order to prevent the damage that is corroded of water source heat pump units 1 internal exchanger equipment, need between water source heat pump units 1 and cesspool 6, increase a sewage heat exchanger 3.When water source heat pump units 1 started, water resource heat pump sewage side water pump 2, sewage (waste water) recirculating pump 4 and water resource heat pump circulating pump 5 also started simultaneously, and the transfer of heat in the sewage in the water of attemperater 7, is heated to design temperature with water.
The hot water that laundry unit 12 uses is directly taken from attemperater 7 through laundry unit heat supply water water pump 11.Water temperature in the attemperater 7 generally can be heated to 55 ℃～60 ℃ with heat pump, if the hot water temperature that 12 laundries of laundry unit are used exceeds this water temperature, available Boiler Steam further is heated to temperature required.
If peak, flat, different electricity prices of different periods of paddy have been adopted in the washing emporium electricity consumption, so, can water source heat pump units 1 be arranged on the operation in night, so that utilize more preferential electricity price in night.
Washing emporium utilizes source pump to carry out the hot water that system produced of Waste Heat Recovery, compares with the traditional fuel heating, can save 50%～60% fuel cost, and energy-saving effect is very obvious, and the period of recouping investments in equipment of recovery system also can be controlled in 2～3 years.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to the technical scheme and the design of above description.
