Dust-free production method and equipment for building gypsum powder

The invention belongs to the technical field of atmosphere dust pollution control, and particularly relates to a building gypsum powder dust-free production method and equipment, the building gypsum powder dust-free production equipment comprises a gypsum powder production line, the gypsum powder production line comprises a mineral separation module, a calcination module, a crushing module, a sorting module and a purification module, and the purification module comprises a dust removal assembly and a desulfurization assembly. The dust removal assembly is used for carrying out dust removal treatment on flue gas generated in the production process and then conveying the flue gas to the desulfurization assembly for desulfurization purification treatment; according to the cloth bag dust removal equipment, the cleaning cavity is formed in the partition plate, dry hot air flow is injected into the cleaning cavity regularly, the humidity of the dust removal filter bag is reduced, smoke impurities attached to the dus
