摘要:

热力发电厂余热资源丰富,且存在锅炉烟气排入大气环境导致的"白羽"现象。为此,国内外学者对烟气余热利用展开了大量研究,其中吸收式热泵作为余热驱动的能级提升装置被广泛应用于区域集中供热和供冷领域。针对目前余热回收领域中应用的回热、多效、多级和压缩-吸收复合的吸收式热泵技术进行综述,并提出一种由双级吸收热泵、升温型压缩吸收耦合热泵和三级烟气换热器组成的烟气余热全热回收系统。该系统基于烟气余热能量梯级利用原理,将烟气由145℃降为40℃以下,同时制取70℃以上的一次热网供暖热水,有效地提升能源利用效率,减少"白羽"现象的产生。

Abstract:

The thermal power plant is rich in waste heat resources, and there is a phenomenon of "white feather" caused by the exhaust of boiler flue gas into the atmosphere. Domestic and foreign scholars have carried out a lot of research on the utilization of waste heat of flue gas. Absorption heat pump is widely used in the field of district central heating and cooling for energy level lifting device driven by waste heat. The regenerative, multi-effect, multi-stage and compression-absorption composite absorption heat pump technologies used in the field of waste heat recovery was reviewed. A flue gas waste heat recovery system consisting of a two-stage absorption heat pump, a temperature rising compression absorption coupling heat pump and a three-stage flue gas heat exchanger was proposed. The system is based on the principle of use of flue as waste heat energy cascade, reducing the flue gas from 145℃ to below 40℃, and obtaining a heating network hot water above 70℃, which can effectively improve the energy efficiency and reduce the "white feather" phenomenon.

Key words: flue gas waste heat recovery, absorption heat pump, multi-effect, multi-stage, compressionabsorption composite
