A waste gas combustion treatment equipment

Abstract

The invention discloses waste gas combustion treatment equipment, which comprises a waste gas intake system, a combustion system and a chimney (9). The waste gas intake system comprises a fan (1), a flame arrester (2), an intake pipeline (3), The hot gas pipeline (4), the air intake pipeline (3) are connected through the chimney (9) and the heat exchanger (7) in the combustion system; the combustion system includes a burner (5), a combustion chamber (6), a heat exchanger Heater (7), catalyst bed (8); described burner (5) is arranged on combustion chamber (6) hearth interior close to intake end, and described combustion chamber (6) one end is provided with fuel gas and combustion-supporting air inlet, The other end is connected with the heat exchanger (7); the intake pipeline (3) communicates with the hot gas pipeline (4) and the burner (5) through the heat exchanger (7); the catalyst bed (8) is located in the heat exchanger (7) ) and the middle of the chimney (9). The equipment is energy-saving and the catalyst is easy to replace.

Description

technical field [0001] The invention relates to a combustion device, in particular to a device for combustion treatment of amine waste gas. Background technique [0002] With the rapid development of economy and industry, air pollution is becoming more and more serious, which has caused great damage to the earth environment on which human beings live. There are usually two methods of combustion to treat organic waste gas: direct combustion and catalytic combustion. The direct combustion method is an oxidation reaction of organic waste gas at a high temperature of 620-850°C. Generally, there are complete oxidation reactions and incomplete oxidation reactions between 620-760°C. The fully oxidized organic waste gas is 60%-70%. Completely oxidized The end product of the reaction is CO 2 and H 2 O, the incomplete oxidation reaction is oxygen-containing organic compounds and CO. As a method aimed at purification, such a result is not ideal. When the temperature is 760-850°C, ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, most of the gas incinerators of the direct combustion method enter the combustion chamber directly, or enter the combustion chamber after being mixed with air, and the waste heat of the exhaust gas at the outlet is not effectively used, and the energy consumption is high; while the structure of the incinerator used in the catalytic combustion method is often The catalyst bed is set inside the combustion chamber for direct catalytic combustion. Such a structure makes it troublesome to replace and regenerate the catalyst.
