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, is the temperature that continuously absorbs low-temperature heat source when unit operation.Waste water in current chemical plant, after absorption heat pump, cannot meet user to the discontinuous requirement of production technology water.
Utility model content
Technology of the present utility model is dealt with problems and is: for the required discontinuous problem of water in prior art, provide a kind of for the discontinuous residual neat recovering system of production technology water.
Technical solution of the present utility model is: a kind of for the discontinuous residual neat recovering system of production technology water, comprise absorption heat pump, rear water tank, water pump, booster 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; The spent hot water in chemical plant is as the input of plate type heat exchanger, by becoming the spent hot water of low temperature after plate type heat exchanger heat exchange, export, be that spent hot water's its heat in plate type heat exchanger is 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 by after booster pump as the input of the absorber part of absorption heat pump, the output of absorber part is connected with the input of condenser; Low temperature clear water after pressurization after absorption heat pump heat exchange as the output of condenser, become the clear water after heating, after water tank later, supply with user, to meet the discontinuous requirement of user's production technology water, the steam of having saved the required consumption of this part clear water temperature rise, reaches 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 chemical plant spent hot water, the water storage function of water tank after simultaneously utilizing, to meet user to the discontinuous demand of production technology water, whole system is realized waste water and is recycled and heat supply, improve water reuse rate, effectively save the energy.
Accompanying drawing explanation
Fig. 1 is described in the utility model for the discontinuous residual neat recovering system structural representation of production technology water.
The specific embodiment
A kind of for the discontinuous residual neat recovering system of production technology water, as shown in Figure 1, comprise absorption heat pump, rear water tank, water pump, booster 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; Chemical plant 40 degree or higher spent hot water are as the input of plate type heat exchanger, by becoming the spent hot water of low temperature 20 degree left and right after plate type heat exchanger heat exchange, export, be that spent hot water's its heat in plate type heat exchanger is 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) by after booster pump as the input of the absorber part of absorption heat pump, the output of absorber part is connected with the input of condenser; Low temperature clear water after pressurization as the output of condenser, becomes the clear water of 85～90 after heating degree after absorption heat pump heat exchange, and after water tank later, supply user, to meet the discontinuous requirement of user's production technology water.
It should be noted that, because water tank is positioned at that side of the condenser portion of absorption heat pump, so be called rear water tank.
The content not being described in detail in the utility model description belongs to the known prior art of professional and technical personnel in the field.
