Description
Technical field
The utility model relates to a kind of printing and dyeing mill waste-heat recovery device, relates in particular to the waste heat continuous recovery system for printing and dyeing mill's forming machine waste gas.
Background technology
Printing and dyeing mill's low temperature waste gas 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 toxic emission 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 waste gas 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, continuously to absorb the temperature of low-temperature heat source when unit operation in sizing, 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 waste gas in current printing and dyeing mill, greatly affect efficiency of heat exchanger.In addition, the output of current absorption heat pump is difficult to meet the demand of user to discontinuous hot water, 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, the steam of need to spending to buy.
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 printing and dyeing mill's forming machine exhaust gas source, a kind of waste heat continuous recovery system based on air water heat-exchanger rig is provided.
Technical solution of the present utility model is: a kind of waste heat continuous recovery system for printing and dyeing mill's forming machine waste gas, comprise absorption heat pump, air preheater, filter, water pump, rear water tank and air water heat-exchanger rig, 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 forming machine steam-out (SO), be output as condensed water; The output of evaporator section is connected with air water heat-exchanger rig, evaporator section be input as running water, running water forms recirculated water by evaporimeter, water pump and the air water heat-exchanger rig of absorption heat pump, this recirculated water absorbs heat from air water heat-exchanger rig, bring heat into after evaporimeter release heat, and then get back to the heat absorption of air water heat-exchanger rig; After the waste gas of printing and dyeing mill filters out impurities by filter, as the input of air water heat-exchanger rig, discharge by the waste gas that becomes low temperature after the heat exchange of air water heat-exchanger rig, be waste gas by filter after in air water heat-exchanger rig 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, become the clear water after heating by water pump, 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 waste gas of printing and dyeing mill, utilize filter by the impurity filtering in waste gas, again with after air water heat-exchanger rig 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, be hot blast by cold air heating, 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.
Brief description of the drawings
Fig. 1 is the waste heat continuous recovery system structural representation for printing and dyeing mill's forming machine waste gas described in the utility model.
Detailed description of the invention
A kind of waste heat continuous recovery system for printing and dyeing mill's forming machine waste gas, as shown in Figure 1, comprise absorption heat pump, air preheater, filter, water pump, rear water tank and air water heat-exchanger rig, 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 forming machine steam-out (SO), be output as condensed water; The output of evaporator section is connected with air water heat-exchanger rig, 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 air water heat-exchanger rig, this recirculated water absorbs heat from air water heat-exchanger rig, bring heat into after evaporimeter release heat, and then get back to the heat absorption of air water heat-exchanger rig; After printing and dyeing mill 40 spends or higher waste gas filters out impurities by filter, as the input of air water heat-exchanger rig, discharge by becoming the waste gas that low temperature 20 is spent or temperature is lower after the heat exchange of air water heat-exchanger rig, be waste gas by filter after in air water heat-exchanger rig 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 20 is spent the clear water of (mean annual temperature) 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, become the clear water of rear 85 degree of heating by water pump, 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, be the hot blast of 70 degree by the cold air heating of 20 degree, then supply with user, to meet the intermittent process requirements 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 in the time that user needs discontinuity air, can carry out heat exchange by water pump and air preheater to cold wind by intermittent the clear water after absorption heat pump heat exchange discontinuously.
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.
