After the holiday, the environmental inspection will strike again, how should the workshop carry out dust removal?

After the National Day, starting from October, the most severe period of air pollution inspection will begin in the year, and the environmental protection department that has completed the holiday will also start the environmental inspection in the region.
According to the regulations on air pollution prevention and control in autumn and winter of 2018, Beijing-Tianjin-Hebei and surrounding areas will once again become the key inspection targets.
Since the environmental management in autumn and winter is mainly directed at air pollution, soot emissions are naturally the main target of environmental inspection, and many welding workshops will be affected.
As a metal thermal processing method, welding is widely used in the field of machining. Almost all factories have a number of welding machines, which is very convenient for production and processing. At the same time, welding will also produce a large amount of welding fumes, which will cause serious air pollution after the workshop. Therefore, the environmental protection department has made detailed regulations on the welding fume treatment, so it is imperative to carry out dust removal in the workshop.
There are many types of dust removal equipment, but there are two main types of welding fume removal equipment, mobile welding fume purifiers and centralized dedusting systems. Different types of dedusting equipment are used differently for different welding conditions.
The welding workshop with few welding points and small concentration, small welding workpieces and few stations is preferred to use a mobile welding fume purifier. This kind of dedusting equipment is designed for dust removal of a single welding point. When using, the welding of the suction arm is first suspended. Above the point, adjust the direction of the suction hood, align the welding points, and after opening the equipment, the welding fume purifier will capture the emitted welding fumes through the air volume generated by the fan, filter the soot particles through the filter element, and then discharge the purified air.
However, mobile fume purifiers are limited in size and cannot meet the dust removal requirements of more and larger welding operations, so a centralized dust removal system is required. The principle of welding fume purification in the centralized dust removal system and the mobile welding fume purifier core is the same, but the difference in the collection and collection of soot is very different, so the volume shape of the two is different.
The centralized dust removal system separates the dust collecting hood from the dust removing main engine and the fan. Each welding station has a custom-sized dust collecting hood to absorb the dust. The dust removing system will send the dust to the host for unified purification treatment. Finally, Then discharge the air into the 15M high altitude.
The biggest feature of this centralized dust removal system is that it can customize the dust removal system specifications according to the workshop conditions, carry out unified dust removal, adapt to the operation requirements of large workshops, and can carry out organized discharge to meet environmental protection requirements.
