Abstract

The invention discloses a continuous organic waste gas catalytic purification device and a running method thereof, relates to a waste gas treatment technology, and aims to solve the problem that the prior art is not suitable for low-concentration organic waste gas. The continuous organic waste gas catalytic purification device is characterized by comprising an air inlet pipe, an exhaust pipe, a primary catalytic combustion device, a smoke exhaust barrel, at least five adsorption beds and a heater, wherein the adsorption beds are communicated with the air inlet pipe, and are provided with air inlet valves; the adsorption beds are communicated with the exhaust pipe, and are provided with air outlet valves; the heater is communicated with the adsorption beds, and heating valves are arranged between the heater and each adsorption bed respectively; the primary catalytic combustion device is communicated with the adsorption beds, and connection valves are arranged between the primary catalytic combustion device and each adsorption bed respectively; and the air outlet end of the primary catalytic combustion device is communicated with the smoke exhaust barrel. The continuous organic wastegas catalytic purification device disclosed by the invention can not only be suitable for treating the low-concentration organic waste gas, but improve the purifying effect of high-concentration organic waste gas.

Description

technical field [0001] The invention relates to waste gas treatment technology, more specifically, it relates to a continuous organic waste gas catalytic purification device and its operating method. Background technique [0002] Regenerative catalytic combustion method (also known as RCO) is an effective organic waste gas treatment method, and it is also an internationally recognized energy-saving organic waste gas treatment device, especially suitable for adsorption and desorption of high-concentration organic waste gas; its working characteristics are : Raise the waste gas containing high concentration of organic solvent to a certain temperature, and use catalyst to make the organic waste gas burn without flame at a lower light-off temperature, and oxidize and decompose into CO2 and H2O, and release a lot of heat energy at the same time. [0003] At present, the commonly used catalytic combustion device consists of a four-way reversing valve and two catalytic combustion b...
