A heat exchange system of heat recovery exchanger

Abstract

The invention relates to a heat exchange system of a heat recovery exchanger, and aims to provide the heat exchange system with good heat exchange effect, high heat transfer temperature difference andcircular heat returning. A main structure of the heat exchange system is arranged as a heat exchanger; one end of the heat exchanger is connected with a heat circulating fan; a filter area is arranged at the front end of the heat exchanger; the downstream of the filter area is arranged as a plane heat exchange area; the downstream of the plane heat exchange area is arranged as a spiral heat exchange area; the downstream of the spiral heat exchange area is arranged as a disordered heat exchange area; the downstream of the disordered heat exchange area is arranged as a horn heat exchange area;and the downstream of the horn heat exchange area is arranged as a hot air flow separation area. Multiple heat exchange tubes are arranged in the heat exchange system, and ripples are arranged in theheat exchange tubes, so that the heat transfer and mass transfer disturbance is increased, the heat transfer and the mass transfer are facilitated, and the heat exchange efficiency is improved; fluidscircularly transfer heat in the heat exchanger by multiple times, so that the heat transfer temperature difference is increased, and the heat transfer requirements are met; and the system adopts semi-automatic operation, and is flexible in control, simple and practical.

Description

technical field [0001] The invention relates to the technical field of heat recovery and exchange, in particular to a heat exchange system of a heat recovery exchanger. Background technique [0002] The air compressor heat recovery device has been widely used in industrial and mining enterprises and daily life needs, and the effect of energy saving and emission reduction is obvious. However, the heat recovery devices on the market are not perfect, and the potential for energy saving can be further tapped. For example, the existing heat recovery switches are all installed in a split type. The main defect of this structure is that the distance between the heat exchanger and the heat demand device is long, which will inevitably lead to loss of heat energy and waste of materials, and fail to achieve energy saving. The best effect of emission reduction; in addition, the long distance between the heat exchanger and the heat demand device causes the pipeline to be messy, and the o...

Problems solved by technology

[0003] The general heat exchange system is similar to the traditional heat exchanger, the heat exchange efficiency is low, and the heat transfer is one-time. It is equipped with a circular heat transfer structure, which causes most of the heat in the thermal fluid passing through the heat exchanger to be lost as waste heat; The exported heat after heat exchange inside the heat exchanger is not provided with a circulation heat recovery structure between the heat exchanger, resulting in poor heat transfer effect and low heat utilization rate in general heat exchange systems, resulting in a large waste of energy resources
