Problems solved by technology
However, during the baking process, the volatilization of the zinc material will produce a certain amount of waste gas, and the direct discharge of the waste gas does not meet the national environmental protection standards. In the prior art, the conventional harmful gases in the waste gas are generally treated, but the treatment of special organic gases is incomplete.
When processing special gases, the energy consumption is relatively large, and the existing environmental protection exhaust gas removal device is only a single unit, which cannot treat the exhaust gas generated on the color coating line in an environmentally friendly and energy-saving manner.

The invention applies to the technical field of waste gas treatment and provides a desorption waste gas treatment device. The desorption waste gas treatment device comprises an adsorption and desorption device, a high-temperature cracking device and a discharge device, wherein a filter device is arranged in the adsorption and desorption device, and the adsorption and desorption device is connected with the discharge device and the high-temperature cracking device through a waste gas conveying pipe and a desorption waste gas heat exchange pipe; the high-temperature cracking device comprises a plurality of heat exchange chambers and catalysis chambers, and the heat exchange chambers and the catalysis chambers are connected with the discharge device and a pretreatment device through a conveying pipe; the pretreatment device comprises a steam oven and a passivation oven which are connected through a pretreatment pipe, and the pretreatment device is connected with the discharge device through the waste gas conveying pipe. Therefore, organic waste gas can be treated more thoroughly, the organic waste gas can be reused while environmental pollution is reduced, and use efficiency is increased.
Description
technical field [0001] The invention relates to the technical field of exhaust gas treatment, in particular to a desorption exhaust gas treatment device. Background technique [0002] The color-coated steel plate is made of cold-rolled steel strip and galvanized steel strip (electro-galvanized and hot-dip galvanized) as the substrate on the continuous unit, after surface pretreatment (degreasing and chemical treatment), and coated with a layer by roller coating Or multi-layer liquid paint, melt the board obtained after baking and cooling. On the continuous unit, the cold-rolled steel strip and galvanized steel strip (electro-galvanized and hot-dip galvanized) are used as the substrate, after surface pretreatment (degreasing and chemical treatment), and one or more layers of liquid coating are applied by roller coating. The coating, the plate obtained after baking and cooling is the coated steel plate. Because the coating can have various colors, it is customary to call the...
