Lithium Bromide Absorption Heat Pump Application In The Power Plant And Economical Analysis

In the process of power plant, water cycle (i.e. more than hot water) is the cooling effect, will take away the process unit production equipment to produce heat, the heat will through the drying tower directly discharged into the environment to will not only cause thermal pollution on the environment, but also a waste of energy. And this part of the heat is low temperature, although the content is huge, but only higher than the ambient temperature of 10 degrees Celsius, it is difficult to use directly in the production process. If this part of the heat can be recycled, it will produce huge economic benefits, environmental benefits and social benefits.Is the use of power plant waste hot water heat pump LiBr absorption heat pump system, through to the heating water heating equipment. It can effectively recycle the heat of the remaining hot water, and has the characteristics of low temperature heat recovery. The use of the driving steam for the five part of the pumping unit, so that in the production process and reduce the pumping capacity, to further improve the efficiency of the unit.Based on in Guodian Jin to the recovery of waste heat of Thermal Power Co., Ltd. centralized heating project, introduces the lithium bromide absorption type heat pump working principle, structure of heat pump system, heat pump system and the unit in the docking problem, in the production process of power plant how to cast stop and run to the accident analysis and processing, after the shutdown maintenance problems. And through the waste heat recovery centralized heating project performance test of performance of heat pump and pump put into operation and investment operation conditions of economic comparison, draw heat pump in returns to power, returns to the hot effective amount of coal saving, further proof of the lithium bromide absorption type heat pump in recycling low-temperature waste heat of important significance.
