Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a device and method for regenerating antifreeze solution of a supergravity heat source tower. Background technique [0002] The heat source tower heat pump system can use outdoor air as a low-temperature heat source in winter, absorb low-grade heat from the air, work in the heat pump mode, run stably, and have good technical and economic potential. It has received more attention and application in recent years. Its main The feature is that the antifreeze solution and air are used to exchange heat and mass in the heat source tower, which can effectively absorb sensible heat and latent heat in the air, and is not affected by frost after condensation of water vapor, avoiding defrosting operation during operation. Since the antifreeze solution absorbs the moisture in the air, it needs to be regenerated. The regeneration methods include thermal regeneration and reverse osmosis...

Problems solved by technology

But at present, there are two problems faced by reverse osmosis regeneration of antifreeze solution: one is that due to the high concentration of antifreeze solution, in order to prevent excessive osmotic pressure, the circulation rate of dilute solution will be large. If the high-pressure concentrated solution is directly discharged, It will cause a large loss of pressure energy, but to recover the liquid pressure energy, it is necessary to use an expensive liquid energy recovery device, which greatly reduces the technical and economic value

On the other hand, the high-pressure water pump used in the reverse osmosis process has the disadvantages of many compression links, large dynamic and static conversion losses, and low efficiency. Moreover, since the amount of water required for reverse osmosis in the heat source tower heat pump system is small, it is difficult to select a suitable high pressure pump. Pump
