Abstract

The invention discloses a waste gas treatment method capable of circulating and filtering mixed gas, comprising a circulating spray device, a circulating filtering device, an auxiliary air intake system and an exhaust control valve, using the waste gas treatment method capable of circulating and filtering mixed gas The method includes performing spraying treatment and multi-layer filtering treatment in sequence, controlling the exhaust rate at the exhaust control valve according to the actual filtering treatment conditions, splitting the mixed gas through the exhaust port of the circulation filter device and the outer circulation pipeline, and partially The exhaust gas is discharged after multi-layer filtration in the circulating filter device, and the diverted circulating gas flows back to the circulating spraying device through the circulating pipeline of the circulating filtering device for further spraying and filtering cycle treatment. The exhaust gas treatment method capable of circulating and filtering the mixed gas can appropriately improve the treatment quality of the overall treatment process, facilitate flexible adjustment and treatment of gases with different concentrations and flow rates, and improve the flexibility of the treatment process.

Description

technical field [0001] The invention relates to the technical field related to energy saving and environmental protection, in particular to a waste gas treatment method capable of circulating and filtering mixed gas. Background technique [0002] With the improvement of energy saving and environmental protection requirements and awareness, when discharging boiler waste gas and other waste gas mixed gases, it is usually necessary to carry out corresponding filtering process to reduce the impurities in the discharged gas, so as to reduce the air pollution caused by dust and other impurities. , in addition to some chemical treatment methods, etc., the most common treatment methods usually include spray dust reduction and corresponding physical filtration measures. [0003] In the existing waste gas treatment process, the waste gas is usually directly processed step by step through the corresponding spray dust reduction and filter mechanisms, etc., but the treatment effect step ...
