Welding fume purifying environment-friendly device

The invention discloses a welding fume purifying environment-friendly device, comprising a purifying case, a dedusting box, a universal gas absorption arm, a sterilizing purifying box and an electrical control case; the dedusting box and the electrical control case are respectively arranged at the bottom of the inner wall of the purifying case; the left side of the top of the dedusting box is connected with the sterilizing purifying box by the top of an airflow connecting pipe. The welding fume purifying environment-friendly device adopts a liquid dedusting technology, so that a dedusting effect is more perfect; a filter screen plate is arranged in the middle of the inner cavity of the dedusting box, and can effectively disperse gas to be purified; more air bubbles are generated in dedusting liquid to increase a contact area between the gas and the dedusting liquid, and a dedusting purifying effect is improved; a U-shaped structure is formed between the inner cavity of the purifying box and a sterilizing plate, so that the contact time between the air and the sterilizing plate is longer and a sterilizing effect is better.
