Welding fume is a kind of fume produced under the condition of high temperature combustion when the welding electrode is in contact with the weldment in the process of electric welding. This fume contains manganese dioxide, nitrogen oxides, fluoride, ozone, etc., which floats in the air and causes harm to human body. Inhalation of this smoke can cause dizziness, headache, cough, chest tightness and shortness of breath, which can seriously lead to smoke poisoning or pneumoconiosis. Working in this smoke environment for a long time is more likely to cause cancer. Therefore, welding fume purification is one of the key topics in the environmental protection industry, and also one of the key areas of Smear fume purification.

 

 

Treatment of welding smoke and dust

 

In addition to the air volume and purification efficiency of the main engine

 

The choice of dust cover is also very important

 

Welding fume collection forms are usually as follows

 

I. Suction arm type

 

In view of the welding conditions of concentrated welding points and fixed welding stations, universal suction arm type can be adopted. The suction arm swings in a universal way and hovers at will, so that the suction hood position can be adjusted according to the welding point, and the dust source point can be collected at close distance.

 

Second, the environmental protection welding gun type

 

A dust suction port is arranged on the welding gun, and smoke and dust are sucked away by close-range high-pressure dust suction.

 

Third, the top suction hood type

 

IV. Welding Room Type

 

V. Telescopic room type

 

Six, the whole workshop self-circulation purification integrated machine
