Recovered afterheat and compressed steam driven absorption heat pump device

Abstract

The invention provides a recovered afterheat and compressed steam driven absorption heat pump device. The device comprises three parts of an afterheat recovery system, a steam compression system and an absorption heat pump system; industrial afterheat is recycled; the afterheat is used for low-pressure flash evaporation of working medium water; and a steam compressor recompresses steam to drive the absorption heat pump device to achieve dual effects of afterheat recovery and building air conditioning. The absorption heat pump system driven by recovery of the industrial afterheat is used for conditioning of building air to realize winter heating and summer refrigeration, so that the people comfort requirements can be met, the comprehensive utilization of the industrial afterheat can be realized, the environmental pollution in heating seasons is reduced, the industrial afterheat is effectively recovered, the energy utilization efficiency is improved, and the environmental pollution problem caused by traditional fire coal heating is prevented.

Description

technical field [0001] The invention relates to an absorption heat pump device driven by compressed steam for recovering waste heat, which is used for waste heat recovery and air conditioning, and belongs to the technical field of energy and heat pumps. Background technique [0002] Today in the era of large industries, energy consumption is increasing day by day. Along with the massive energy consumption, a large amount of waste heat will be generated in industrial production. These waste heat usually have the characteristics of large amount, wide temperature range and many forms. If they are directly discharged, they will affect surrounding environment, causing thermal pollution problems. How to recycle and rationally utilize waste heat generated in production, effectively improve energy utilization efficiency, and reduce environmental thermal impact has become a hot topic of research in recent years. [0003] At present, the waste heat generated in industrial production ...
