The invention discloses a waste heat recovering system capable of continuously generating steam aiming at impure waste water resources. The system comprises a second-type absorption heat pump, a front water tank, a filtering device, a water pump and a plate type heat exchanging device, wherein cooling water is input into a condenser of the second-type absorption heat pump and is output after heat exchanging, the output end of an evaporator is connected with the input end of a generator, the output end of the generator is connected with the plate type heat exchanging device, tap water is input into the evaporator and forms circulating water through the evaporator, the generator, the water pump and the plate type heat exchanging device, discontinuous waste hot water is changed into continuous waste hot water through the front water tank, input into the plate type heat exchanging device after impurities are filtered out through the filtering device, and then discharged as low-temperature waste hot water through heat exchanging. Low-temperature clear water is input into an absorber after passing through the water pump, and then is output as steam needed by a user. The system has the advantages that the utilization rate of the waste hot water is high, and the steam generating efficiency is high.
Description
Technical field
The present invention relates to a kind of printing and dyeing mill waste-heat recovery device, relate in particular to for the impure residual neat recovering system of producing continuously steam of waste water source.
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 problem discontinuous and that contain a large amount of impurity in the spent hot water 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.
Summary of the invention
Technology of the present invention is dealt with problems and is: for the discontinuous and impure problem in used heat water source in prior art, provide a kind of for the impure residual neat recovering system of producing continuously steam of waste water source.
Technical solution of the present invention is: a kind of for the impure residual neat recovering system of producing continuously steam of waste water source, comprise second-kind absorption-type heat pump, front water tank, filter, water pump and plate type heat exchanger, wherein second-kind absorption-type heat pump is divided into generator part, evaporator section, absorber part and condenser portion, condenser portion be input as cooling water, after second-kind absorption-type heat pump carries out heat exchange, output to cooling tower; The output of evaporator section is connected with the input of generator, the output of generator is connected with plate type heat exchanger, evaporator section be input as running water, running water forms recirculated water by evaporimeter, generator, water pump and the plate type heat exchanger of second-kind absorption-type heat pump, this recirculated water absorbs heat from plate type heat exchanger, bring heat into after evaporimeter and generator release heat, and then get back to plate type heat exchanger heat absorption; After the spent hot water of printing and dyeing mill stores by front water tank, become continuous spent hot water, again after filter filters out impurities, input as plate type heat exchanger, by becoming the spent hot water of low temperature after plate type heat exchanger heat exchange, discharge, be that spent hot water is constantly absorbed after front water tank and filter in plate type heat exchanger, be then discharged in evaporimeter and generator, these heats are used for heating by second-kind absorption-type heat pump the low temperature clear water that enters absorber; Low temperature clear water by after water pump as the input of the absorber part of second-kind absorption-type heat pump, absorber part is output as the required steam of user, to meet user's process requirements, to have saved, make this part clear water become the needed steam of steam, reach energy-conservation object.
The present invention's advantage is compared with prior art: the present invention is by adopting second-kind absorption-type heat pump, utilize a large amount of middle temperature-heat-sources to produce the high temperature heat that can be utilized on a small quantity, adopting under the condition of cooling water, produce the high temperature heating agent higher than low-temperature heat source temperature, the conveying of realization from low temperature to high temperature, utilize temperature more than 60 ℃ spent hot waters can obtain than waste heat source temperature high 40 ℃～80 ℃ of left and right (secondary intensification), be no more than heating agent or the steam of 175 ℃, to meet user's process requirements, spent hot water becomes spent hot water continuously by front water tank, then passing through filter can be by a large amount of impurity filtering, improve the heat exchange efficiency of plate type heat exchanger, realized the high efficiente callback utilization of waste water and produced steam, effectively save the energy.
