Description
Technical field
The utility model relates to a kind of printing and dyeing mill waste-heat recovery device, relates in particular to the residual neat recovering system that a large amount of impurity spent hot waters are contained in a kind of printing and dyeing mill.
Background technology
Printing and dyeing mill's low-temperature wastewater is by treatment system or directly discharge the huge heat-energy losses of formation, makes printing and dyeing mill's capacity usage ratio low, not only causes mass energy waste, has also seriously polluted environment simultaneously.The discharge of wastewater of printing and dyeing mill is the ubiquitous problem in China and even the world.But along with the development of heat pump techniques, the particularly appearance of large high-temperature water resource heat pump, makes printing and dyeing mill's 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 there is the problem of a large amount of impurity in spent hot water in current printing and dyeing mill, greatly affect the efficiency of plate type heat exchanger, be difficult to meet the demand of user to hot water.
Utility model content
Technology of the present utility model is dealt with problems and is: in prior art for impure spent hot water's source problem, a kind of printing and dyeing mill residual neat recovering system is provided.
Technical solution of the present utility model is: a kind of printing and dyeing mill residual neat recovering system, comprise absorption heat pump, front water tank, filter, 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 printing and dyeing mill's 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 of printing and dyeing mill becomes after continuous spent hot water by front water tank, after filtering out impurities by filter again, as the input of plate type heat exchanger, by becoming spent hot water's output of low temperature after plate type heat exchanger heat exchange, be spent hot water by front water tank and 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 by the input as the absorber part of absorption heat pump after booster pump, and 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 after heating after absorption heat pump heat exchange, then supplies with user, to meet the required technological requirement of user, has saved the steam of 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 the discrete spent hot water of printing and dyeing mill, the water storage function of water tank before simultaneously utilizing, the interrupted industrial wastewater of printing and dyeing mill is become continuously, adopt the impurity of filtering spent hot water after filter simultaneously, improve the heat exchange efficiency of plate type heat exchanger, to meet consumers' demand, whole system is realized waste water and is recycled and heat supply, improve water reuse rate, effectively save the energy.
Brief description of the drawings
Fig. 1 is residual neat recovering system structural representation described in the utility model.
Detailed description of the invention
A kind of printing and dyeing mill residual neat recovering system, as shown in Figure 1, comprise absorption heat pump, front water tank, filter, 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 printing and dyeing mill's 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; Printing and dyeing mill 40 spends or higher spent hot water becomes after continuous spent hot water by front water tank, after filtering out impurities by filter again, as the input of plate type heat exchanger, by becoming spent hot water's output of low temperature 20 degree left and right after plate type heat exchanger heat exchange, be spent hot water by front water tank and 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 that low temperature 20 is spent (mean annual temperature) is by the input as the absorber part of absorption heat pump after booster pump, and 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 the degree of 85～90 after heating after absorption heat pump heat exchange, then supplies with user, to meet the required technological requirement of user.
It should be noted that, because water tank is positioned at that side of the evaporator section of absorption heat pump, be therefore called front water tank.
