Abstract

The invention discloses a waste heat recovery and comprehensive utilization system of an industrial furnace group. The waste heat recovery and comprehensive utilization system of the industrial furnace group comprises a heat collecting unit, a first heat exchange unit, a second heat exchange unit, a first heat supply unit and a second heat supply unit. The heat collecting units are formed by connecting multiple heat collecting subunits in parallel. Heat pipe heat exchangers in the heat collecting units are communicated with the same water collector inlet. A water collector outlet is communicated with a plate heat exchanger of the first heat exchange unit and a plate heat exchanger of the second heat exchange unit through pipelines. The plate heat exchanger of the first heat exchange unit and the plate heat exchanger of the second heat exchange unit are communicated with the same water distributor inlet, and the plate heat exchanger of the first heat exchange unit and the plate heat exchanger of the second heat exchange unit are communicated with a first heat storage tank and a second heat storage tank through circulating water pumps. The first heat storage tank is communicated with the first heat supply unit through a water pump, the second heat storage tank is communicated with a plate heat exchanger of the second heat supply unit through a circulating water pump, and the plate heat exchanger of the second heat supply unit is communicated with the second heat supply unit through a circulating water pump. According to the waste heat recovery and comprehensive utilization system of the industrial furnace group, comprehensive utilization of waste heat in the aspects of heat collecting and technology production is achieved, and recovery and utilization of the waste heat are balanced through heat storage and heat release.

Description

technical field [0001] The invention relates to a waste heat recovery comprehensive utilization system, in particular to an industrial furnace group waste heat recovery comprehensive utilization system. Background technique [0002] Industrial furnaces arranged in large-scale clusters, such as various types of equipment such as heat treatment furnaces, forging furnaces, curing furnaces, sintering kilns, etc., which use gas, oil, coal, etc. High temperature flue gas contains a lot of waste heat. The waste heat of the high-temperature flue gas emitted by the above-mentioned industrial furnaces is recycled to produce hot water, and the produced hot water is used or stored in a coordinated manner, and finally realizes the comprehensive utilization of hot water or heat energy in life, production, heating, etc. , is an important way to save energy and reduce emissions. However, the key issue that restricts the waste heat recovery and effective utilization of industrial furnaces ...
