Harm of welding fume exhaust gas:
There are two hazards: (1) During the welding process, a large amount of metal welding dust will be produced. The diameter of metal powder produced by welding is usually less than 0.3 micron, which is easier to inhale into the lungs and cause pathological changes. Long-term exposure to welding dust can cause pneumoconiosis, manganese poisoning and metal heat and other occupational diseases in the case of high concentration of welding dust and without corresponding elimination measures. (2) Under the action of high temperature and strong ultraviolet radiation of welding arc, a variety of harmful gases are formed around the arc. Ozone is a kind of irritating gaseous body, which is light blue. When the concentration is high, the odor is fishy, and the high concentration of ozone is slightly acidic. Ozone has a strong stimulating effect on the respiratory tract and lungs. Ozone often causes cough, chest tightness, loss of appetite, fatigue, dizziness, systemic pain, and bronchitis and pulmonary edema in severe cases.
Sources of welding fume:
Welding process includes manual arc welding, self-shielded arc welding, gas shielded arc welding and other welding processes, harmful gases will be produced in the production process.
Equipment advantages of welding dust purifier:
1. It can be flexibly moved in any position of the factory building, and is not subject to the constraints of unstable dust emission points.
2. The equipment is equipped with universal casters to facilitate the positioning of the equipment.
3. Unmatched treatment efficiency, under rated treatment air volume, the removal rate of smoke and dust is more than 9%. The clean air discharged after treatment can be directly circulated in the workshop.
4. Adopt the filter core type purification method, high efficiency and high precision (PTFE) membrane-covered filter material, high purification efficiency, low cost of consumables, no frequent replacement, saving environmental protection.
5. The equipment has built-in automatic pulse ash cleaning device to maintain constant air suction capacity and constant purification capacity (optional according to requirements).
6. The control system specially designed for the equipment is safe and stable, equipped with high-voltage leakage protection.
7. The universal suction arm can be hovered at any position in the three-dimensional space. 360 degrees can easily and flexibly reach the dust spots in any direction. Welders can work more efficiently.
8. Under special working conditions, the corresponding dust-collecting cover can be selected according to the site.
9. Through special shock absorption and noise reduction treatment, the noise of the equipment is ensured to be environmentally friendly.
10. The equipment is simple to operate and easy to clean and maintain.
11. The pollution source can be handled by mobile single machine or multi-station centralized treatment.
Scope of application:
Widely used in chemical industry, electronics, metal processing and other industries, welding, polishing, cutting, grinding and other processes generated in the dust, smoke purification. Welding dust control equipment has developed from single, fixed and large-scale to complete, combined, portable and miniaturized.
Product characteristics of welding fume purifier:
1. The filter element adopts imported membrane-coated polyester filter cartridge, and the efficiency is over 95%.
2. Fume collection methods of different specifications can be fitted according to the site.
3. According to the requirement of on-site workstations, single and multi-workstations can be allocated.
4. Fully automatic frequency conversion control with PLC, easy to use, lower energy consumption
5. Fully automatic pulse ash removal, more stable performance, easy maintenance
6. More reasonable structure design to ensure safe and lasting operation of equipment
7. Intelligent control, optional remote intelligent remote control
