Improved regenerative catalytic combustion device

Abstract

The invention provides an improved regenerative catalytic combustion device, which can be also used as a general catalytic combustion equipment, has wider application range and effectively reduces production cost. The improved regenerative catalytic combustion device comprises a first reaction chamber and a second reaction chamber; a combustion chamber is arranged between the first reaction chamber and the second reaction chamber and an auxiliary burner is arranged at the top of the combustion chamber; the first combustion chamber comprises a first regenerator and a first catalyst bed, the second combustion chamber comprises a second regenerator and a second catalyst bed, and a movable connector part is arranged between the first regenerator and the first catalyst bed as well as the secondregenerator and the second catalyst bed.

Description

technical field [0001] The invention relates to the technical field of organic waste gas treatment, in particular to an improved regenerative catalytic combustion device. Background technique [0002] In industrial production, waste gas with a large amount of organic substances or toxic and harmful gases is often produced. If it is directly discharged, it will cause serious harm to the human body and the environment. Therefore, many countries have regulated the discharge of such waste gas and required The toxic gas produced in industrial production is purified, and the regenerative catalytic combustion device is one of the equipment for purifying organic waste gas. [0003] Existing regenerative catalytic combustion devices such as figure 1 and 2 As shown, it is by switching the gas flow to make the exhaust gas according to "the first regenerator 1a in the first reaction chamber 1↔ the first catalytic bed 1b in the first reaction chamber 1↔ the combustion chamber 2↔ the se...

[0003] Existing regenerative catalytic combustion devices such as figure 1 and 2 As shown, it is by switching the gas flow to make the exhaust gas according to "the first regenerator 1a in the first reaction chamber 1↔ the first catalytic bed 1b in the first reaction chamber 1↔ the combustion chamber 2↔ the second reaction chamber 3 The path of the second catalytic bed 3b↔the second regenerator 3a" in the second reaction chamber 3, that is, as figure 2 The gas flow direction of route I or route II shown in the figure: the exhaust gas is preheated by the heat storage body of a reaction chamber, and then under the catalytic action of the catalytic bed of the reaction chamber, it is oxidized, burned and purified at a lower temperature in the combustion chamber at the top, and passed through The other reaction chamber discharges and transfers the heat to the heat storage body in this reaction chamber to realize the purification treatment of organic waste gas and achieve the effect of energy saving and emission reduction, but it is suitable for medium and high waste gas flow or low calorific value waste gas. Low exhaust gas flow or high calorific value exhaust gas requires the use of catalytic combustion equipment, which limits the application range and increases production costs
