Embodiment Construction
[0016] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0017] as attached figure 1 As shown, the present invention provides a second type of absorption heat pump for solar assisted heating, the heat pump includes an evaporator, a condenser, a heat exchanger, a solar collector, an absorber, a heat exchanger, a regenerator and a cooler ;
[0018] The external sewage enters the tube side of the evaporator and is discharged after heat exchange. The shell side inlet of the evaporator is connected to the condenser, and a pump is connected to the pipeline between the evaporator and the condenser to pump the condensed water in the condenser into the evaporator. In the middle; the sewage will heat and evaporate the condensed water entering the shell side of the evaporator from the condenser, and the shell side outlet of the evaporator is connected to the absorber; the absorber, heat exchanger and regenerator are conne...

The invention discloses a solar-assisted heating second-type absorption heat pump. The heat pump comprises an evaporator, a condenser, a heat exchanger, a solar heat collector, an absorber, a heat exchanger, a regenerator and a cooler; external sewage enters the evaporator for heat exchange and then is discharged, the evaporator is connected with the condenser, and a shell pass outlet of the evaporator is connected with the absorber; the absorber, the heat exchanger and the regenerator form a heat exchange loop; the other path of external sewage flows through the regenerator to ensure the regeneration of a lithium bromide solution in the heat exchanger, and the regenerator is connected with the condenser; the condenser, the cooler and a pump body form a cooling circulation loop; heat medium water enters the absorber and then is heated by 5-8 DEG C to flow into the solar heat collector, the heat medium water is introduced into the heat exchanger after the temperature of the heat mediumwater is increased to a set value by the solar heat collector, and the heat medium water heats heating water to a set value and then continuously circulates in a pipeline. By means of the absorption heat pump, the operation cost is reduced by 50% or above, the recycling period is greatly shortened, and economic benefits are huge.
Description
technical field [0001] The invention relates to the technical field of waste heat utilization of oil extraction sewage in the petroleum industry, in particular to a second-type absorption hybrid heat pump that utilizes solar energy for auxiliary heating. Background technique [0002] At present, the water content of crude oil extracted from domestic oilfields is already very high (generally above 90%). After the crude oil is extracted from the ground, it will be aggregated to the regional joint station through the transfer station along the way to dehydrate the crude oil. Due to the different physical properties of crude oil in different geographical locations in China, the treatment process is not exactly the same. However, the main process is to realize oil-water separation through sedimentation and other methods, and reduce the water content of crude oil to below 0.03%. [0003] In the process of oil-water separation, the separated sewage still has a certain amount of he...
