[0002] Flame cutting is a common method for rough processing of steel plates. Flame cutting is gas cutting. Traditionally, acetylene gas was used for cutting, and later propane was used. Now natural gas cutting has emerged. Due to its abundant reserves, low price, and no pollution, natural gas has become the first choice for flame cutting.
[0003] When the flame cutting machine is working, smoke and dust will be generated, and the smoke and dust will carry a lot of metal dust. However, since most flame cutting machines are not equipped with exhaust gas treatment devices when working, these smoke and dust gases are inhaled by the human body, thus affecting the health of the workers.

Usually, the smoke is initially filtered through a filter plate or a filter net, and then filtered and adsorbed through activated carbon. However, the activated carbon is in a static state, resulting in that part of the activated carbon cannot be effectively utilized, thereby reducing the smoke treatment effect. In addition, only the above-mentioned simple filtering method results in insufficient smoke treatment and poor purification effect. Utility Model Content
