Waste gas treatment system with pretreatment, zeolite rotation and RCO and waste gas treatment method thereof

Abstract

The invention relates to a waste gas treatment system with pretreatment, zeolite rotation and RCO, the waste gas treatment system comprises a pretreatment device, a zeolite rotation device, an RCO device and a smoke exhaust pipe, the pretreatment device is provided with a gas inlet pipe for waste gas to enter and a gas outlet pipe fixedly connected with the zeolite rotation device, the zeolite rotation device comprises a first shell, a mounting cavity is formed in the first shell, and a lower bottom plate and a plurality of supports fixedly connected to the lower bottom plate are arranged in the mounting cavity .A plurality of zeolite modules clamped between the first mounting groove and the second mounting groove are arranged between the two brackets, the first shell is further provided with a cover plate, the lower end of the cover plate extends downwards to form a first partition plate, and a first containing cavity and a second containing cavity are formed among the lower bottom plate, the support, the zeolite module and the first partition plate. The structure is simple, dismounting, mounting and adjusting are convenient, the working efficiency is improved, and the applicationworking environment is wide.

Description

【Technical field】 [0001] The invention relates to the field of exhaust gas treatment, in particular to an exhaust gas treatment system with pretreatment, zeolite rotation and RCO and an exhaust gas treatment method thereof. 【Background technique】 [0002] In the prior art, the zeolite wheel often adopts the superposition of one or several zeolites to perform adsorption, desorption and other work. This type of zeolite wheel has a large volume, and lifting equipment is required for disassembly and assembly. It is inconvenient to replace when a failure occurs. The simple superposition of zeolite will also lead to problems such as poor adsorption and desorption effects and short service life of zeolite rotation; for RCO devices, the existing technology often uses the reversing action of the reversing valve to continuously switch between exhaust gas entry and combustion treatment When the reversing effect of the reversing valve is invalid or the reversing is slow, it is difficult...

Problems solved by technology

[0002] In the prior art, the zeolite wheel often adopts the superposition of one or several zeolites to perform adsorption, desorption and other work. This type of zeolite wheel has a large volume, and lifting equipment is required for disassembly and assembly. It is inconvenient to replace when a failure occurs. The simple superposition of zeolite will also lead to problems such as poor adsorption and desorption effects and short service life of zeolite rotation; for RCO devices, the existing technology often uses the reversing action of the reversing valve to continuously switch between exhaust gas entry and combustion treatment When the reversing effect of the reversing valve is invalid or the reversing is slow, it is difficult to find the problem, resulting in failures and even stagnation of the entire work; therefore, the existing technology cannot meet our needs
