Hebei Longmen CNC cutting machine manufacturers teach you reasonable gas emissions

　　 When using a gantry CNC cutting machine, the melting of the surface of the material will form a large amount of harmful gas. Especially when using a gantry CNC cutting machine to cut galvanized sheets and other materials, the smoke and harmful gases generated will be greater. In order to reduce the impact of smoke and dust, manufacturers are equipped with more dust removal devices to achieve the effect, but from a cost point of view, both dry and wet dust removal have considerable costs. Below, the Hebei Longmen CNC cutting machine manufacturer will take everyone to learn in detail how to deal with the cutting gas reasonably.

　　Hebei Gantry CNC cutting machine manufacturer’s suggestion:

　　1. Exhaust gas treatment

　　 Exhaust gas treatment is usually performed only locally on the cutting surface , Especially the local air flow, so that the local workplace will not be polluted by harmful substances and maintain a good air environment. Generally, the local exhaust fan unit includes a hood, an air duct, a purification system and a fan. According to different gas collection methods, partial exhaust can be divided into fixed partial exhaust system and mobile partial exhaust system.

　　The fixed local exhaust system is mainly used in large-scale CNC cutting workshops. The operating places and operating methods of the workers in these workshops are fixed, and the position of the air collecting hood can be fixed at a time according to the actual situation. The working state of the mobile local exhaust system is relatively flexible. According to different working conditions, different working attitudes can be adopted to ensure the processing efficiency and the convenience of the operators. Numerical control cutting flue gas and harmful gas purification system usually adopts bag type or electrostatic precipitator combined with adsorbent, which has high processing efficiency and stable working conditions.

　　2. Ventilation treatment

　　 Full ventilation, also called dilution ventilation, refers to the use of clean air to dilute the concentration of harmful substances in the indoor air so that the concentration of harmful substances in the indoor air does not exceed The high allowable concentration specified by the sanitary standard. At the same time, it continuously pollutes the air or collects and purifies the air.

　　 Comprehensive ventilation includes natural ventilation and mechanical ventilation. In foreign countries, outdoor CNC cutting or outdoor CNC cutting usually adopts natural ventilation. For indoor operation, mechanical ventilation is usually used. The welding flue gas in the workshop is discharged to the outdoors through an axial fan installed on the wall or ceiling, or is recycled into the workshop after being purified by a purifier to reduce the concentration of the flue gas in the workshop. Circulating purified air to solve the energy loss in the workshop, which is widely used abroad.

　　 The above is the gas treatment of the gantry CNC cutting machine brought to you by the Hebei gantry CNC cutting machine manufacturer. Each manufacturer should pay attention to the emission of cutting gas, which has a direct impact As far as the health of workers is concerned, if you want to know more about it, you can pay more attention to our website.
