Embodiment Construction

[0015] figure 1 Among them, a heat treatment waste gas combustion purification and waste heat recovery device, including a heat treatment heating furnace 1 that generates high-temperature waste gas in the production process, the waste gas of the heat treatment heating furnace can overflow from the gas outlet above the heat treatment heating furnace body, and the gas outlet is hinged. There is an air outlet cover fixedly connected to the periphery of the air valve and the air outlet, and the air outlet is located in the air outlet cover. An air outlet spring is fixedly connected between the air outlet valve and the air outlet cover. Ensure that the high-temperature exhaust gas can enter the combustion chamber smoothly; a combustion air pipe is installed on the top of the combustion chamber, and the gas outlet of the combustion chamber is connected with the air collection chamber. In the air collection chamber, an arc door of the air collection chamber is hinged at the gas outlet...

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...
