Description
Technical Field

Background
In the production process of industries such as metallurgy, coal chemical industry, salt chemical industry and the like, a large amount of high-temperature process circulating cooling water or process wastewater exists and contains a large amount of high-temperature heat energy. Because the water quality components are complex, the conventional heat exchange equipment is easy to pollute, corrode and even block, only a few northern enterprises can develop and utilize, most northern enterprises are used for building heating or process water heating, and in summer of most southern enterprises or northern enterprises, the waste heat is directly discharged into the atmosphere, so that the heat waste and the heat pollution are caused. If the high-temperature waste water heat can be used as an input heat source of an evaporator and a generator of a second-class lithium bromide absorption heat pump, the method is a perfect supplementary scheme for preparing the high-temperature heat, and the high-temperature waste water heat can be fully utilized all the year round.
The lithium bromide absorption heat pump is mainly composed of a generator, a condenser, an evaporator, an absorber, a heat exchanger, a circulating pump and the like. In the operation process of the second type lithium bromide absorption type all-in-one machine, refrigerant water is heated by a heat source in an evaporator and is evaporated into refrigerant water vapor; then the solution enters an absorber, is absorbed by a lithium bromide concentrated solution in the absorber, the concentration of the solution is reduced, a dilute solution obtained after absorbing the refrigerant water vapor flows out of the absorber, flows through a solution heat exchanger and then enters a generator, the lithium bromide dilute solution is heated by a heat source in the generator to generate the refrigerant water vapor, and is concentrated into the concentrated solution at the same time, and the concentrated solution is conveyed to the absorber by a solution pump through the heat exchanger to absorb the refrigerant water vapor again; the low-pressure refrigerant water vapor generated in the generator enters the condenser, is cooled into refrigerant water by cooling water in the condenser, is conveyed to the evaporator by the refrigerant water pump, is heated and evaporated again, and thus the circulation is completed
The circulation is kept, and heat is continuously produced.
However, the evaporator and the generator of the second-class lithium bromide absorption all-in-one machine usually adopt shell-tube or plate-type equal-dividing-wall heat exchangers, the requirement on water quality is high, the water quality components of the high-temperature wastewater are complex, and the generator is easy to be polluted, corroded and even blocked, so that the high-temperature wastewater cannot be directly used as a heat source of the second-class lithium bromide absorption all-in-one machine. If the heat energy of the lithium bromide is transferred to clean medium water by adopting proper intermediate heat exchange equipment and then enters the lithium bromide unit, the process flow is complex, the occupied space is large, the investment cost is high, and heat transfer loss can be caused.
The boiling point of water can be reduced along with the reduction of the environmental pressure, for example, a negative pressure environment is artificially manufactured, so that the high-temperature wastewater is subjected to flash evaporation, clean steam is generated and is directly conveyed into the generator and the evaporator to release heat, and the high-temperature wastewater is directly used as a heat source of the secondary lithium bromide absorption type all-in-one machine.
