Problems solved by technology
[0003] Using activated carbon adsorption and desorption to treat the exhaust gas used for the coating production of the inner coating The biggest problem is that the organic matter in the exhaust gas contains butanone substances, which have a low ignition point and are easy to burn during the desorption process and damage the activated carbon. , and even lead to violent combustion, causing a large amount of activated carbon to be scrapped

The invention relates to the technical field of exhaust gas treatment devices, in particular to a pipe fitting inner coating production waste gas treatment system. The pipe fitting inner coating production waste gas treatment system comprises a cyclic thermal oxidation RTO treatment device, the cyclic thermal oxidation RTO treatment device comprises an oxidation chamber, a heat storage chamber anda reversing chamber, the cyclic thermal oxidation RTO treatment device collects exhaust gas generated by volatilization of organic matters in a discharging unit, the exhaust gas enters a filter chamber through a waste gas pipeline to process dust and particulate matters, the exhaust gas is driven by a supply fan and controlled by a reversing valve to enter a heat storage chamber and an oxidationchamber to complete high-temperature cyclic oxidation, the generated clean higher temperature gas is driven by a exhaust fan, a part of the clean higher temperature gas passes through a preheater andis discharged into the atmosphere through a chimney, and the other part of the clean higher temperature gas is respectively connected to the combustion-supporting air pipeline units of the oxidation chamber, a drying furnace and a combustion chamber of a curing furnace through a return pipeline to be mixed with the respective gas for combustion. According to the waste gas treatment system, it is guaranteed that most harmful organic matters produced by coating production in the pipe fitting are oxidized and removed and continuous standard discharge is realized.
Description
technical field [0001] The invention relates to the technical field of waste gas treatment devices, in particular to a waste gas treatment system for pipe inner coating production. Background technique [0002] At present, the waste gas generated during the production process of the inner coating conveying pipe is mostly treated by adsorption, desorption and catalytic oxidation treatment, that is, the activated carbon absorbs the harmful components in the waste gas and then discharges them up to the standard. After a period of operation, the harmful components in the activated carbon are removed. The substance is desorbed by higher temperature gas, and then the activated carbon resumes its activity to continue to effectively adsorb harmful components in the exhaust gas. The harmful gases from the forced desorption need to enter the electric heating catalytic oxidation chamber to undergo a chemical reaction, oxidize the harmful components into harmless substances such as wate...
