1. The welding fume extraction arm determines the dust removal efficiency and emission concentration required by the dust removal equipment in accordance with the relevant national emission standards, indoor hygiene standards and practical possibilities.

2. According to the requirements of electrical control and safe production, determine the distance between all internal components in the dust removal equipment, and keep the distance in line with the requirements of the gas flow law.

3. The discharge concentration of welding fume extraction arm meets the environmental protection discharge standards or specific regulations, and the landing concentration of dust or other harmful substances cannot exceed the sanitary protection limit.

4. The welding fume extraction arm has advanced technology, novel shape and optimized structure. The dust removal equipment has obvious technical characteristics such as "high efficiency, sealing, strength and rigidity".

5. According to the characteristics of flue gas (temperature, humidity, dew point, pressure, etc.), determine the structure of the equipment, the selection of materials, and the main measures such as ash transport and discharge. (3) The main technical and economic indicators have reached the advanced level at home and abroad.

6. According to the characteristics of the dust (dust concentration, particle size, viscosity, etc.), determine the flow rate of the flue gas in the dust removal equipment, the required filter area, the filter material and the dust removal method of the dust removal equipment.

7. The dust removal equipment has supporting technical safeguard measures.
