The invention discloses a ship segmented coating waste gas treatment system. The system comprises two sets of independent waste gas pretreatment and exhaust systems and a set of waste gas purification system, and each set of waste gas pretreatment and exhaust system comprises a waste gas inlet valve, a dry filter box and an exhaust fan; and the waste gas purification system comprises a waste gas mixing box, a zeolite rotating wheel, a chimney, a heat exchanger, a desorption fan, a fresh air filter box, an RTO fan, RTO equipment, a high-temperature mixing box, a high-temperature gas taking valve, a high-temperature bypass valve, a high-temperature gas taking adjusting valve and an RTO fresh air valve. Two workshops share one set of waste gas treatment system, and different rotating wheel concentration multiples and RTO equipment treatment air volume are set in different operation modes, so that on one hand, the equipment allowance is increased, peak clipping and homogenization of VOCs concentration are realized, and stable standard reaching is ensured; and on the other hand, self-heating operation of the system under various working conditions is guaranteed.
Description
technical field [0001] The invention relates to the field of waste gas treatment, in particular to a system and method for treating ship segmental coating waste gas. Background technique [0002] As an important part of the heavy industry, the shipbuilding industry plays an important role in my country's social economy. In the shipbuilding process, steel plates are generally made into multiple segments, and then assembled into hulls from the segments. Therefore, segmental coating is the most important source of organized emissions of volatile organic waste gases (VOCs) in the shipbuilding industry. Difficult to handle effectively. In view of the increasingly stringent national and local emission standards, it is particularly critical to efficiently treat the waste gas from segmental painting to meet the emission standards and reduce investment and operating costs. Contents of the invention [0003] The object of the present invention is to provide a system and method for...
