Description
Technical field
The utility model relates to a kind of chemical plant waste-heat recovery device, relate in particular to a kind of for waste water source impure 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 when unit operation, is the temperature that continuously absorbs low-temperature heat source, and there is the problem of a large amount of impurity in the spent hot water in current chemical plant, greatly affect the efficiency of plate type heat exchanger, cannot make full use of existing spent hot water's heat.And existing hot-air acquisition methods is to obtain by the new wind of Steam Heating, this part steam need to spend to buy, and cannot obtain intermittent hot-air.
Utility model content
Technology of the present utility model is dealt with problems and is: in prior art for the problem of the impure existence of waste water source, provide the residual neat recovering system of air laser heating.
Technical solution of the present utility model is: a kind of for waste water source impure by the residual neat recovering system of air laser heating, comprise absorption heat pump, air preheater, filter, 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; After the spent hot water in chemical plant filters out impurities by filter, input as plate type heat exchanger, by becoming the spent hot water of low temperature after plate type heat exchanger heat exchange, discharge, be spent hot water by filter after in plate type heat exchanger its heat be constantly absorbed, 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, 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, utilize filter by the impurity filtering in spent hot water, 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 rear water tank and water pump and air preheater, by cold air heating, it is hot blast, to meet user to intermittent process requirements, whole system is realized Waste Heat Recovery utilization and heat supply, improve heat utilization rate, effectively save the energy.
Accompanying drawing explanation
Fig. 1 be described in the utility model for waste water source impure by the residual neat recovering system structural representation of air laser heating.
The specific embodiment
A kind of for waste water source impure by the residual neat recovering system of air laser heating, as shown in Figure 1, comprise absorption heat pump, air preheater, filter, 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 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 filter out impurities by filter, input as plate type heat exchanger, by becoming low temperature 20 degree or the lower spent hot water of temperature after plate type heat exchanger heat exchange, discharge, be spent hot water by filter after in plate type heat exchanger its heat be constantly absorbed, 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, 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, by the cold air heating of 20 degree, be the hot blast of 70 degree, then supply with user, to meet the requirement of the intermittent technique of user.
It should be noted that, because water tank is positioned at that side of the condenser portion of absorption heat pump, therefore be called rear water tank, the effect of rear water tank is exactly when user needs discontinuity air, can be discontinuously by water pump and air preheater, cold wind be carried out to heat exchange by the clear water after absorption heat pump heat exchange is intermittent.
