A multi-source fluid waste heat recovery and utilization system

Abstract

The invention discloses a multisource waste heat recycling system. The multisource waste heat recycling system comprises a heat source system, a heat source end heat exchange system, a softening tank water treatment system, a heat pump system, a heat storage hot water system, a multipurpose heat exchange system, a heat application system and an intelligent control system. According to the multisource waste heat recycling system, an independent inner circulating system is arranged, thus, the heat pump heat source end temperature can be ensured, meanwhile, dirt and impurities in water can be prevented from making contact with each other, separate softening treatment can be conducted on circulating water, and the heat source end water quality is ensured; in addition, mutual contact between the heat pump system and liquid with different components is isolated through the inner circulating system, the cleaning times and the maintenance times are decreased, and hence the stability and the reliability of operation of the heat pump system are ensured; a middle pool is arranged for energy storage, during the production peak, excess heat is recycled to the middle pool, and during the production trough, the middle pool is opened, and heat energy is transmitted into a heat energy storage system so that the requirement of a workshop can be met; and the middle pool is adopted for energy storage, so that the cost is reduced, and meanwhile, the excess heat is further collected.

Description

technical field [0001] The invention relates to waste heat recovery and utilization technology, in particular to a multi-source fluid waste heat recovery and utilization system. Background technique [0002] In order to save energy and reduce production costs, most manufacturers will build waste heat recovery and utilization systems to recover and utilize the heat generated in the production process, but most of the existing waste heat recovery systems are single heat source recovery and utilization systems, which cannot A variety of heat sources with different properties are recovered and utilized. When there is too much waste heat in the peak production period of the workshop, it is impossible to fully store too much waste heat. When the production of the workshop is low, the storage of waste heat is not enough to meet the utilization of waste heat in the workshop. Building multiple waste heat recovery systems will undoubtedly increase the investment of the manufacturer, ...

Problems solved by technology

[0002] In order to save energy and reduce production costs, most manufacturers will build waste heat recovery and utilization systems to recover and utilize the heat generated in the production process, but most of the existing waste heat recovery systems are single heat source recovery and utilization systems, which cannot Recover a variety of heat sources with different properties and use them

When there is too much waste heat in the peak production period of the workshop, it is impossible to fully store too much waste heat; when the production of the workshop is low, the storage of waste heat is not enough to meet the utilization of waste heat in the workshop

If multiple waste heat recovery systems are built, it will undoubtedly increase the investment of the manufacturer, and if there is too much waste heat in the workshop, it is necessary to build a cooling tower to dissipate the waste heat, increasing unnecessary capital investment, and the efficiency of recycling is not high
