Abstract
The utility model provides a printing and dyeing factory afterheat continuous reclaiming system. The system comprises an absorption type heat pump, a filtering device, a rear water-storing tank, a water pump, a boosting pump and a plate type heat exchange device. After being purified by the filtering device, printing and dyeing factory waste hot water is connected with the plate type heat exchange device, after heat is exchanged by the plate type heat exchange device, the waste hot water becomes low-temperature waste water, after being processed by an evaporator of the absorption type heat pump, the water pump and the plate type heat exchange device, tap water becomes circulating water, and after low-temperature clean water is processed by the boosting pump and heat of the low-temperature clean water is absorbed by an absorber part of the absorption type heat pump, the clean water is output by a condenser part of the absorption type heat pump, and the output high-temperature water is supplied to users, so that the technical requirement of the users is met. The system provided by the utility model has the advantages of continuous utilization of waste hot water, high efficiency, high heat energy reclaiming and utilization rate, energy conservation, emission reduction and the like.
Description
Technical field
The utility model relates to a kind of printing and dyeing mill waste-heat recovery device, relates in particular to a kind of printing and dyeing mill waste heat continuous recovery system.
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.Yet 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 when unit operation, is the temperature that continuously absorbs low-temperature heat source, but there is the problem of a large amount of impurity in the 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: for the required discontinuous and problem that spent hot water is impure of water in prior art, provide a kind of printing and dyeing mill waste heat continuous recovery system.
Technical solution of the present utility model is: a kind of printing and dyeing mill waste heat continuous recovery system, comprise absorption heat pump, filter, 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 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 removes after impurity by filter, input as plate type heat exchanger, by becoming the spent hot water of low temperature after plate type heat exchanger heat exchange, export, 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 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 user, produce the discontinuous requirement of 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 the spent hot water of printing and dyeing mill, spent hot water can be by a large amount of impurity filterings by filter, improve the heat exchange efficiency of plate type heat exchanger, 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 printing and dyeing mill described in the utility model waste heat continuous recovery system structural representation.
The specific embodiment
A kind of printing and dyeing mill waste heat continuous recovery system, as shown in Figure 1, comprise absorption heat pump, filter, 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, evaporator section be input as running water, running water passes through water pump, the evaporimeter of absorption heat pump becomes 20 degree or lower, 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, printing and dyeing mill's 40 degree or higher spent hot water remove after impurity by filter, input as 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 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) 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, after water tank later, supplies with user, to meet user's production to the discontinuous requirement of 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.
