Description

A kind of discontinuous by the residual neat recovering system of air laser heating for waste water source
Technical field
The utility model relates to a kind of chemical plant waste-heat recovery device, relates in particular to for waste water source discontinuous by the residual neat recovering system of air laser heating.
Background technology
For chemical plant, the low-temperature wastewater of its generation is by treatment system or directly discharge the huge heat-energy losses of meeting formation, makes chemical plant capacity usage ratio low, not only causes mass energy waste, has also seriously polluted environment simultaneously.Along with the development of heat pump techniques, the particularly appearance of large high-temperature water resource heat pump, makes chemical plant low-temperature wastewater waste heat recovery will become possibility.In addition, absorption heat pump formula is to rely on driving heat source operation, the temperature that absorbs low-temperature heat source water is transferred to the equipment of middle warm water, it in the time of unit operation, is the temperature that continuously absorbs low-temperature heat source, but in the time there is cutout in low-temperature heat source water, heat namely can not be provided continuously, and unit is now still in continuous heat absorption, the temperature of the heat exchanger of absorption heat pump low temperature water inlet front end will sharply decline so, until residual water freezing in pipe, after water build-ups ice, volume can become large, thereby burst low-temperature heat exchange device, whole system paralysis, and existing hot-air acquisition methods is to obtain by the new wind of Steam Heating, this part steam need to spend to buy.
Utility model content
Technology of the present utility model is dealt with problems and is: for the problem existing for the discontinuous residual neat recovering system by air heat of waste water source in prior art, provide residual neat recovering system.
Technical solution of the present utility model is: a kind of discontinuous by the residual neat recovering system of air laser heating for waste water source, comprise absorption heat pump, front water tank, air preheater, water pump, rear water tank and plate type heat exchanger, wherein absorption heat pump is divided into generator part, evaporator section, absorber part and condenser portion, generator part be input as chemical plant steam-out (SO), be output as condensed water; The output of evaporator section is connected with plate type heat exchanger, evaporator section be input as running water, running water forms recirculated water by evaporimeter, water pump and the plate type heat exchanger of absorption heat pump, this recirculated water absorbs heat from plate type heat exchanger, bring heat into after evaporimeter release heat, and then get back to plate type heat exchanger heat absorption; The spent hot water in chemical plant is by after front water tank storage, become continuous spent hot water, be re-used as the input of plate type heat exchanger, discharge by the spent hot water who becomes low temperature after plate type heat exchanger heat exchange, be that spent hot water is constantly absorbed after by front water tank in plate type heat exchanger, then be discharged in evaporimeter, these heats are used for heating by absorption heat pump the low temperature clear water that enters absorber; Low temperature clear water is as the input of the absorber part of absorption heat pump, and the output of absorber part is connected with the input of condenser; Low temperature clear water is after absorption heat pump heat exchange, become the clear water after heating by water pump, warp is water tank and water pump later, again by forming circulation clear water after air preheater, circulation clear water heats cold wind (new wind) in air preheater, and output warm-air supply user, to meet consumers' demand, save this part new wind-warm syndrome and risen the steam of required consumption, reached energy-conservation object.
The utility model advantage is compared with prior art: the utility model is realized waste heat recovery by the heat exchange method of absorption heat pump, reclaim the spent hot water in chemical plant, before utilizing, waste water is become continuous state by water tank, then after being connected with plate type heat exchanger, tap water heating is formed to recirculated water, after being heated up by absorption heat pump, clear water passes through rear water tank and water pump and air preheater, be hot blast by cold air heating, to meet the demand of user to intermittent technique, whole system is realized Waste Heat Recovery utilization and heat supply, improve heat utilization rate, effectively save the energy.
Brief description of the drawings
Fig. 1 is described in the utility model discontinuous by the residual neat recovering system structural representation of air laser heating for waste water source.
Detailed description of the invention
A kind of discontinuous by the residual neat recovering system of air laser heating for waste water source, as shown in Figure 1, comprise absorption heat pump, front water tank, air preheater, water pump, rear water tank and plate type heat exchanger, wherein absorption heat pump is divided into generator part, evaporator section, absorber part and condenser portion, generator part be input as chemical plant steam-out (SO), be output as condensed water; The output of evaporator section is connected with plate type heat exchanger, evaporator section be input as running water, running water becomes 20 degree or lower by the evaporimeter of water pump, absorption heat pump, then form recirculated water by plate type heat exchanger, this recirculated water absorbs heat from plate type heat exchanger, bring heat into after evaporimeter release heat, and then get back to plate type heat exchanger heat absorption; Chemical plant 40 is spent or higher spent hot water passes through after front water tank storage, become continuous spent hot water, be re-used as the input of plate type heat exchanger, discharge by becoming the spent hot water that low temperature 20 is spent or temperature is lower after plate type heat exchanger heat exchange, be that spent hot water is constantly absorbed after by front water tank in plate type heat exchanger, then be discharged in evaporimeter, these heats are used for heating by absorption heat pump the low temperature clear water that enters absorber; Low temperature clear water is as the input of the absorber part of absorption heat pump, and the output of absorber part is connected with the input of condenser; Low temperature 20 is spent the clear water of (mean annual temperature) after absorption heat pump heat exchange, become the clear water of rear 85 degree of heating by water pump, warp is water tank and water pump later, again by forming circulation clear water after air preheater, circulation clear water heats cold wind in air preheater, be the hot blast of 70 degree by the cold air heating of 20 degree, then supply with user, to meet the demand of the intermittent technique of user.
It should be noted that, the water tank that is positioned at that side of the evaporator section of absorption heat pump is called front water tank, the water tank that is positioned at that side of the condenser portion of absorption heat pump is called rear water tank, the effect of rear water tank is exactly in the time that user needs discontinuity air, can carry out heat exchange by water pump and air preheater to cold wind by intermittent the clear water after absorption heat pump heat exchange discontinuously.
