Description

A kind of discontinuous by the residual neat recovering system of air heat for used heat water source
Technical field
The utility model relates to a kind of chemical plant waste-heat recovery device, relates in particular to for used heat water source discontinuous by the residual neat recovering system of air heat.
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 when unit operation, is the temperature that continuously absorbs low-temperature heat source, but when there is cutout in low-temperature heat source water, namely can not provide continuously heat, 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: the problem for existing for the discontinuous residual neat recovering system by air heat in used heat water source in prior art, provides a kind of by the residual neat recovering system of air heat.
Technical solution of the present utility model is: a kind of discontinuous by the residual neat recovering system of air heat for used heat water source, comprise absorption heat pump, front water tank, air preheater, water pump 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; After the spent hot water in chemical plant stores by front water tank, become continuous spent hot water, be connected with plate type heat exchanger again, by becoming the spent hot water of low temperature after plate type heat exchanger heat exchange, export, 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, by water pump, become the clear water after heating, after air preheater, form circulation clear water, circulation clear water heats cold wind (new wind) in air preheater, output warm-air supply user, to meet user's requirement, save this part new wind-warm syndrome and risen the steam of required consumption, reach 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, after spent hot water stores by front water tank, become continuous spent hot water, be connected with plate type heat exchanger again, with after plate type heat exchanger, tap water heating is formed to recirculated water, after being heated up by absorption heat pump, clear water passes through air preheater, by cold air heating, it is hot blast, to meet user's process requirements, whole system is realized discontinuous spent hot water's recycling, improve heat utilization rate, effectively save the energy.
Accompanying drawing explanation
Fig. 1 is described in the utility model discontinuous by the residual neat recovering system structural representation of air heat for used heat water source.
The specific embodiment
A kind of discontinuous by the residual neat recovering system of air heat for used heat water source, as shown in Figure 1, comprise absorption heat pump, front water tank, air preheater, water pump 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 by plate type heat exchanger, form recirculated water, 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; After chemical plant 40 degree or higher spent hot water store by front water tank, become continuous spent hot water, be connected with plate type heat exchanger again, by becoming low temperature 20 degree or the lower spent hot water of temperature after plate type heat exchanger heat exchange, export, 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; The clear water of low temperature 20 degree (mean annual temperature) 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, by water pump, become the clear water of rear 85 degree of heating, after air preheater, form circulation clear water, circulation clear water heats cold wind in air preheater, it by the cold air heating of 20 degree, is the hot blast of 70 degree, then supply with user, to meet user's requirement.
It should be noted that, because water tank is positioned at that side of the evaporator section of absorption heat pump, so be called front water tank.
