Description

Technical Field

[0001] The present application relates to welding fume purification equipment, and in particular to the technical field of welding equipment. Background Art

[0002] Welding fume purification is used in heavy industrial occasions such as steel and special metals. Cutting, welding, welding and other operations are indispensable and important processes. During the operation, a large amount of welding fume will be generated. After workers inhale welding fume for a long time, they will suffer from dizziness, headache, cough, chest tightness and shortness of breath, etc., causing fibrous lesions of lung tissue, namely welder's pneumoconiosis, and accompanied by complications such as manganese poisoning, fluorine poisoning and metal fume fever. Therefore, it is necessary to use purification equipment to treat welding fume, so as to ensure the quality of the processing environment and the health of workers.
