The heavy duty dust collector is used to collect and purify the welding fumes generated during the welding process. A large amount of welding fumes are generated, and grinding welding is one of the processes.

1. Ozone: After the ozone in the welding area is inhaled by the human body, it mainly stimulates the respiratory system and nervous system, causing symptoms such as chest tightness, cough, dizziness, general weakness and unwillingness to eat.

2. Oxides: the main types are N2O, NO, NO2 and N2O5, which are reddish-brown gases, heavier than air, and their toxicity is 4 to 5 times that of NO. In contact with water, they can become nitric acid or nitrous acid, which produces a strong stimulating effect. .

3. Carbon monoxide is easily combined with hemoglobin to form carboxyhemoglobin, which makes hemoglobin lose its ability to carry oxygen and cause tissue suffocation. It has toxic effects on the tissues and cells of the whole body, especially on the cerebral cortex. The carbon monoxide in welding mainly comes from the decomposition/decomposition of carbon dioxide, so a large amount of carbon monoxide gas will be produced in carbon dioxide shielded welding, and only a small amount of carbon monoxide gas will be produced in other arc welding.

4. When fluorine-containing welding materials are involved in welding, a small amount of HF gas can be generated, and HF has a strong stimulus.

For the industrial welding production process, it is necessary to take necessary air dust removal and purification measures to ensure a hygienic and clean working environment, reduce the occurrence of occupational diseases of workers, and improve production quality and work efficiency.
