1, the harm of welding dust and exhaust gas

Welding smoke is formed by oxidation and condensation of steam generated by overheating evaporation of metal and non-metal substances during welding. The smoke produced by welding and cutting has sub-micron particles, and the metal smoke produced is complex in composition, among which MnO2, FeO2 and SiO2 are more harmful to the human body, which can lead to manganese poisoning, silicosis and cancer of welders. According to the test data provided by the German IFA institution, the diameter of dust particles generated by welding and cutting is between 0.1 and 1um, and the diameter of particles below 0.4um accounts for more than 90%, while particles below 0.4um can directly enter the blood through the alveoli, which will seriously endanger human health.

2, the principle and advantages of Huashi dust collector

From the point of view of the welding dust purifier host, the filter area is required to be large, high filtration accuracy, in line with the two basic conditions of the current market is more common and mature filter filter, with a relatively small footprint, high filtration accuracy characteristics, the most critical is the selection of filter materials, according to Jinan Huashi years of industry experience, The selection of filter materials for welding smoke generally must have the following characteristics:

(1) Filtration accuracy: the filtration efficiency of 0.3µm dust particles is more than 99%.

(2) With flame retardant characteristics: because the welding smoke will have sparks, it is easier to ignite the filter material.

(3) The equipment has the function of pulse blowback: the amount of welding dust is relatively large, if there is no automatic ash cleaning function, the filter is easy to jam, and the cleaning is more troublesome.
