Abstract

The invention discloses a directly-heated type second-class heat pump, and belongs to the technical field of industrial waste heat recovery. According to the heat pump, the problem that an existing second-class absorption heat pump cannot utilize industrial waste water which are prone to scaling and high in corrosivity as a waste heat source is solved. The heat pump is characterized in that the interior of an evaporator and the interior of a generator are vacuumized through a flash evaporation vacuum pump, the upper portion of a first flash evaporation chamber communicates with a first waste water inlet pipe, the upper portion of a second flash evaporation chamber communicates with a second waste water inlet pip, waste water is subjected to flash evaporation in the two flash evaporation chambers, steam after flash evaporation moves upwards and correspondingly exchanges heat with refrigerant water in a refrigerant water cavity and a dilute lithium bromide solution in a lithium bromide solution cavity, the falling film evaporation is performed after the refrigerant water in the refrigerant water cavity exchanges heat, the steam after evaporation enters an absorber, the refrigerant water in the dilute lithium bromide solution is heated and evaporated, and the steam after evaporation enters a condenser.

Description

technical field [0001] The invention relates to a direct-heating type II heat pump, which belongs to the technical field of industrial waste heat recovery. Background technique [0002] The second type of lithium bromide absorption heat pump unit is a device that recycles heat energy from a low-temperature heat source (such as waste hot water) to produce high-temperature heat medium (hot water) for the required process or heating, and realizes the transfer of heat energy from low temperature to high temperature. It does not require a higher temperature heat source to drive, but requires a lower temperature cooling water. It uses a low-temperature heat source (waste hot water) as a driving heat source, and under the condition of using low-temperature cooling water, it produces a heat medium (hot water) whose temperature is higher than that of the low-temperature heat source. [0003] At present, the low-temperature heat source used by the second-type heat pump can only be re...
