Industrial waste heat and residual pressure comprehensive recovery system

Abstract

The invention discloses an industrial waste heat and residual pressure comprehensive recovery system. The system comprises an adsorption type refrigeration assembly and an adsorbate supercharger which are connected through a pipeline to form an adsorbate circulation loop, the adsorption type refrigeration assembly is connected with a waste heat guide pipe, the waste heat guide pipe is used for desorbing a working medium pair of the adsorption type refrigeration assembly, the adsorbate enters the adsorbate supercharger, and the adsorbate supercharger is driven to work by the industrial residual pressure, so that the gaseous adsorbate in the adsorbate supercharger is compressed and then returns to the adsorption type refrigeration assembly. The system has the beneficial effects that (1), waste heat and residual pressure can be comprehensively recycled at the same time, (2), the restriction of adsorbate desorption capacity and rate of an adsorption bed in a traditional solid chemical adsorption type refrigeration / energy storage system by the ambient temperature of a condenser is relieved, the working efficiency and the waste heat recovery efficiency are improved, and (3), moreover, the system is simple in structure, low in investment cost, flexible in installation, easy in process transformation and convenient to operate.

Description

technical field [0001] The invention belongs to the field of heat energy recovery, and in particular relates to a comprehensive recovery system for industrial waste heat and pressure. Background technique [0002] Facing the current increasingly severe energy problems, recycling low-grade heat energy and industrial residual pressure is one of the main routes to overcome the growing energy demand that restricts the sustainable development of the economy and society. Due to the particularity of the process in industrial production, the effective utilization rate of energy is generally low, and there are generally a large number of waste heat and pressure of different grades that are not effectively utilized and are directly discharged into the environment, which not only causes serious energy waste And pollute the environment. In recent years, the solid chemical adsorption thermal energy storage and refrigeration technology using low-grade thermal energy as the driving force ...
