Dust explosion risk assessment method and system for electrostatic powder spraying enterprise

The invention relates to a dust explosion risk assessment method and system for an electrostatic powder spraying enterprise. The method comprises the following steps: constructing a dust explosion risk assessment index system, and determining first-level indexes, second-level indexes and third-level indexes in the dust explosion risk assessment index system, wherein the first-level indexes comprise a plurality of the second-level indexes, and the second-level indexes comprise a plurality of the third-level indexes; during implementation, determining a weight of each third-level index, determining a risk assessment value of each third-level index of a to-be-assessed electrostatic powder spraying enterprise, and obtaining a risk level of each second-level index according to the weight of each third-level index and the risk assessment value of each third-level index; obtaining the risk level of each first-level index according to the risk level of each second-level index and a preset weight of each second-level
