Several manifestations of occupational respiratory diseases in welding smoke treatment equipment


Occupational respiratory diseases of welding smoke treatment equipment have the following 4 manifestations:
1. Pneumoconiosis Pneumoconiosis refers to diseases that are mainly caused by fibrosis of the lung caused by inhalation of productive dust during the production process. There are different degrees of harm due to the quality and quantity of inhaled dust. There are many types of pneumoconiosis, 12 of which are classified as occupational diseases. They are: silicosis, coal worker pneumoconiosis, graphite pneumoconiosis, carbon black pneumoconiosis, asbestos lung, talc lung, cement lung, mica lung, potter pneumoconiosis, aluminum pneumoconiosis, and electric welding Pneumoconiosis, castor pneumoconiosis.
2. Dust deposition Some metal (iron, barium, tin, etc.) after inhaling dust can react with foreign bodies in the lung tissue and continue to slightly fibrosis, but it is less harmful to the human body. After the dust is removed, the lesion can gradually fade away. .
3. Organic dust caused by different lung diseases Organic dust has different biological effects, such as causing bronchial asthma, cotton dust, occupational allergic pneumonia, mixed pneumoconiosis, etc.
4. The local effect of dust in the respiratory system refers to the atrophic lesions caused by the dust acting on the mucous membrane of the respiratory tract; in addition, pharyngitis, laryngitis, and bronchitis can be formed; acting on the skin can form acne, folliculitis, pyoderma, etc. Metal and abrasive dust can cause corneal damage, resulting in dull corneal sensation and corneal opacity; asphalt soot can cause photosensitivity dermatitis when exposed to sunlight. The poisoning effect of dust refers to the poisoning phenomenon caused by inhalation of toxic dust such as lead, arsenic and manganese.
