Waste heat utilization type steel plate preheating device

Abstract

The invention discloses a waste heat utilization type steel plate preheating device. The device includes a shell, a bracket, a through-hole, a steel plate frame, a shunt box, a universal block, a reflux box, an air intake pipe, an air leakage valve, connecting pipes, an air pipe, a base plate, a purification box, an air outlet pipe, a cutoff sheet, a detection port and a seal box. The shell and the base plate are both transparent and adiabatic steel plate structures, so that the heat generated in the waste gas treatment process can be fully utilized to heat a steel plate, thus avoiding heat loss. The steel plate is seamlessly connected to the shell top through the steel plate frame, thus ensuring full utilization of waste heat; the exhaust gas subjected to reflux treatment by the reflux box enables full emission of exhaust gas with heat in the air pipe, thus reducing heat loss; the vast majority of exhaust gas from the air leakage valve enters the device through the cutoff sheet, and asmall amount flows out from the detection port, thus being convenient for collection; and the purification box is connected to a reflux pipe, so that the exhaust gas flowing back can be purified again and the purification effect can be strengthened.

Description

technical field [0001] The invention belongs to the field of processing equipment, and in particular relates to a waste heat utilization type steel plate preheating device. Background technique [0002] During the operation of almost all industrial machinery, a large amount of heat will be generated, such as industrial boilers or internal combustion engines, etc. These devices will emit a large amount of high-temperature exhaust gas during operation, and these exhaust gases usually enter the exhaust gas treatment device directly, which makes the exhaust gas A large amount of heat is lost in vain, causing great waste, and a large amount of heat is needed when the steel plate is heated, which is extremely serious for the consumption of power resources. If the steel plate is preheated, the heat generated by electricity is greatly reduced. Existing exhaust gas treatment devices or industrial boilers do not make full use of waste heat, which wastes resources and is not conducive ...

[0002] During the operation of almost all industrial machinery, a large amount of heat will be generated, such as industrial boilers or internal combustion engines, etc. These devices will discharge a large amount of high-temperature exhaust gas during operation, and these exhaust gases usually enter the exhaust gas treatment device directly, which makes the exhaust gas A large amount of heat is lost in vain, causing great waste, and when the steel plate is heated, a large amount of heat is needed, which is extremely serious for the consumption of power resources. If the steel plate is preheated, the heat generated by electricity is greatly reduced.

Existing exhaust gas treatment devices or industrial boilers do not make full use of waste heat, which wastes resources and is not conducive to the full utilization of energy cycles
