Dust removal system

The utility model belongs to the technical field of dust removal, and discloses a dust removal system which comprises a primary dust remover, a secondary dust remover, a primary differential pressure transducer and a controller, the primary dust remover is communicated with the secondary dust remover, one end of the primary differential pressure transducer is communicated with an air inlet end of the primary dust remover, and the other end of the primary differential pressure transducer is communicated with an air outlet end of the primary dust remover. The first-stage pressure difference sensor is connected with the controller, when the first-stage dust removal element is damaged, the controller can make a shutdown instruction and prompt the dust remover to be overhauled, meanwhile, the second-stage dust remover can still achieve filtering, gas with a large amount of dust is prevented from entering the next process section, and the reliability of the dust removal system is effectively improved.
