Centralized filtering system of additive manufacturing factory and control method of centralized filtering system

The invention relates to a centralized filtering system of an additive manufacturing factory and a control method of the centralized filtering system, and belongs to the technical field of additive manufacturing. The filtering system comprises an integrated smoke dust filtering device and dust filtering device, an integrated argon gas supply device and argon gas protection device and a unified smoke dust control system and dust control system which are arranged on the periphery of the factory. The system is especially suitable for long-term systematic dust filtration of a plurality of sets ofadditive manufacturing equipment, and reduces the risk of stopping for replacement of filter elements. Besides, the smoke dust filtering device of the equipment and the dust filtering device of the workshop are integrated and arranged outside a workshop in a unified manner, so that the operation risk in dust and dust filtration is reduced, and safety protection and working efficiency are improved;an argon safety control s
