Abstract
The invention provides a printing and dyeing mill waste heat consecutive recovery system based on an air-device heat exchanger device. The printing and dyeing mill waste heat consecutive recovery system comprises an absorbing type heat pump, a filter device, a water pump, an air pre-heater, a back water storage tank and two air-water heat exchange devices. Printing and dyeing mill external steam is input to a generator part of the absorbing type heat pump, and condensed water is output. After impurities of waste gas are filtered by the filter device, the waste gas is connected with a first air-water heat exchange device, is output to a second air-water heat exchange device, and then becomes low-temperature waste water after secondary heat exchange. Tap water forms circulation water between an evaporator, a water pump and a second air-water heat exchange device. Clean water passes through the first air-water heat exchange device, the absorber, the condenser, the water pump, the back water storage tank and the air pre-heater to form circulation clean water. The circulation clean water passes through the absorbing type heat pump and then goes through heat exchange in the air pre-heater, so that cold air is heated into hot air, and technological requirements are met. The printing and dyeing mill waste heat consecutive recovery system has the advantages of being high in heat energy recovery utilization efficiency and the like.
Description
Technical field
The present invention relates to a kind of printing and dyeing mill waste-heat recovery device, relate in particular to the printing and dyeing mill's waste heat continuous recovery system based on air-water heat-exchanger rig.
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.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 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, in sizing, be continuously to absorb the temperature of low-temperature heat source during unit operation, but when there is cutout in low-temperature heat source water, namely can not provide continuously heat, 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 the 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.
Summary of the invention
Technology of the present invention 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 invention is: a kind of printing and dyeing mill's waste heat continuous recovery system based on air-water heat-exchanger rig, comprise absorption heat pump, air preheater, filter, water pump, rear water tank, the first air water heat-exchanger rig and the second 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 the second air water heat-exchanger rig, evaporator section be input as running water, running water forms recirculated water by evaporimeter, water pump and the second air water heat-exchanger rig of absorption heat pump, this recirculated water absorbs heat from the second air water heat-exchanger rig, bring heat into after evaporimeter release heat, and then get back to the second air water heat-exchanger rig heat absorption; After the waste gas of printing and dyeing mill filters out impurities by filter, input as the first air water heat-exchanger rig, waste gas after the cooling of the output of the first air water heat-exchanger rig is as the input of the second air water heat-exchanger rig, entering the waste gas that becomes low temperature after secondary heat exchange discharges, be that waste gas is constantly absorbed after by filter in two air water heat-exchanger rigs, then be discharged in evaporimeter, these heats are used for heating by absorption heat pump the clear water that enters absorber; After low temperature clear water once heats up after the first air water heat-exchanger rig, as the input of the absorber part of absorption heat pump, the output of absorber part is connected with the input of condenser; Clear water after once heating up is after absorption heat pump carries out secondary temperature elevation, 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, output warm-air supply user, to meet consumers' demand, save this part new wind-warm syndrome and risen the steam of required consumption, reach energy-conservation object.
The present invention's advantage is compared with prior art: the present invention realizes 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, clear water is undertaken after secondary temperature elevation by the first air water heat-exchanger rig and absorption heat pump, by 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 has been realized abundant recycling and the heat supply of waste gas by two air water heat-exchanger rigs, improve heat utilization rate, effectively save the energy.
