Safe organic waste gas heat storage, catalysis and oxidation device

Abstract

The invention discloses a safe organic waste gas heat storage, catalysis and oxidation device. The safe organic waste gas heat storage, catalysis and oxidation device is suitable for safely treating organic waste gas with the low concentration and the large air quantity. After organic waste gas is pretreated, the organic waste gas is supercharged by a fan to enter a heat storage and catalysis chamber and an oxidation chamber; the heat storage and catalysis chamber is filled with a heat storage body and a catalyst, organic waste gas is heated in the heat storage and catalysis chamber and is catalyzed and oxidized into water and carbon dioxide under the action of the catalyst and high temperature, and clean treatment is achieved. In order guarantee safety and stability of the organic waste gas treatment process, a series of instrument and control system is arranged for complete equipment. By means of the safe organic waste gas heat storage, catalysis and oxidation device, it can be guaranteed that the complete equipment avoids possible dangerous situations to the largest extent, or safe operation can be achieved in various expectable emergency circumstances.

Description

Technical field [0001] The invention belongs to the technical field of organic waste gas treatment, and particularly relates to a safety type organic waste gas heat storage catalytic oxidation device. Background technique [0002] In the early 1970s (about 1972), the American company Hamon Research-Cottrell introduced RTO to the market for the first time. Since then, as various countries have increasingly strict VOCs emission control, by the 1990s, RTO devices have been very commonly used in the purification of VOCs in European and American countries. [0003] Advantages of RTO and RCO technology: [0004] 1) Almost all waste gas containing organic matter can be treated; [0005] 2) It can treat organic waste gas with large air volume and low concentration; [0006] 3) Large operating flexibility (20%~120%); [0007] 4) Under suitable exhaust gas concentration conditions, self-heating operation can be realized without adding auxiliary fuel; [0008] 5) Organic sediments can be removed p...

AI Technical Summary

Problems solved by technology

[0013] 1) The weight of the device is heavy (because of the ceramic regenerator);

[0014] 2) The volume of the device is large (so large devices can only be placed outdoors);

[0015] 3) Continuous operation as much as possible (restarting takes a long time to heat up);

[0016] 4) Investment costs are relatively high

In addition, during operation, due to the fluctuation of the concentration of combustibles in the exhaust gas, which may unexpectedly increase, the condensation of organic components in the exhaust gas in the pipeline and the accumulation of local areas, or the failure of the internal monitoring system, there are fires and combustion. The danger of exposure
