A comprehensive recovery system for industrial waste heat and pressure

Abstract

The invention discloses a comprehensive recovery system for industrial waste heat and pressure, comprising an adsorption refrigeration component and an adsorbate supercharger, which are connected by pipelines to form an adsorbate circulation loop, wherein the adsorption refrigeration component is connected with a waste heat conduit, the waste heat conduit It is used to desorb the working fluid of the adsorption refrigeration component, and the adsorbate enters the adsorbate supercharger. The adsorbate supercharger is driven by the industrial residual pressure, so that the gaseous adsorbate in the adsorbate supercharger is compressed. Back to the adsorption refrigeration unit. The beneficial effects of the present invention are: (1) the waste heat and pressure can be comprehensively recovered and utilized at the same time, and the ability and rate of desorption of the adsorbate in the adsorption bed in the traditional solid chemical adsorption refrigeration / storage system can be relieved from the constraints of the ambient temperature of the condenser , Improve work efficiency and waste heat recovery efficiency, and the system structure is simple, low investment cost, flexible installation and easy process transformation, easy to operate.

Description

technical field [0001] The invention belongs to the field of heat energy recovery, and in particular relates to an industrial waste heat and pressure comprehensive recovery system. Background technique [0002] Faced with the increasingly severe energy problems, recycling low-grade thermal energy and industrial excess pressure is one of the main routes to overcome the growing demand for energy that restricts sustainable economic and social development. Due to the special process of industrial production, the effective utilization rate of energy is generally low, and there are a large number of waste heat and pressure with different tastes that are not effectively used and are directly discharged into the environment, which not only causes serious energy waste and pollute the environment. In recent years, solid chemisorption thermal energy storage and refrigeration technology using low-grade thermal energy as the driving force has gained relatively high energy storage densit...
