A heat treatment waste gas combustion purification and waste heat recovery device

Abstract

The invention discloses a heat treatment waste gas combustion purification and waste heat recovery device. The device is characterized in that waste gas of a heat treatment heating furnace overflows through an air outlet, enters the lower part of a combustion chamber and fully reacts with the fuel gas in the combustion chamber, the formed high-temperature gas is collected by a gas chamber, the high-temperature gas collected by the gas chamber enters the lower part of a sealing box body and is used for heating water contained in a heating container inside the sealing box body, so that the high-temperature gas is cooled, and the low-temperature gas is discharged into the atmosphere. The heat treatment waste gas combustion purification and waste heat recovery device is reasonable in structural design, convenient to produce, install and operate, easy to maintain and good in safety; the waste gas generated by the heat treatment furnace can be effectively purified, and the waste heat generated by production can be effectively utilized.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a heat treatment waste gas combustion purification and waste heat recovery device. Background technique [0002] The use of heat treatment furnaces to heat-treat industrial products such as mechanical parts produces a large amount of high-temperature waste gas. At present, the main treatment method for these waste gases is to directly discharge them into the atmosphere, which not only pollutes the air, wastes heat resources, but also causes explosions. . The main reason is the lack of relevant technology and equipment, and weak awareness of safety, energy conservation and environmental protection. At present, there is no safe and reliable equipment on the market that can efficiently treat exhaust gas, make full use of waste heat resources. Contents of the invention [0003] The purpose of the present invention is to solve the problems of a large amount...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems in the prior art that a large amount of high-temperature waste gas produced by the heat treatment furnace cannot be purified in time, pollutes the air, and cannot effectively utilize heat energy; it provides a simple structure, easy installation, maintenance, debugging, and use, and is safe. Well, it is a device that does not need to consume energy, can effectively improve the air conditions in the production workshop, and can make full use of the waste heat of production waste for heat treatment waste gas combustion purification and waste heat recovery device
