Analysis of the hazards and filtering methods of polishing and dust removal
Grinding, polishing and dust removal, polishing dust hazards During the grinding and polishing process, a large amount of dust is generated. The dust is visible dust and the dust is fine, especially causing irreversible damage to the operator's lungs. Those who performed lung clearing regularly did not achieve the effect of lung clearing at all.
Grinding, polishing and dust removal filtering method
1. Cloth bag filter method,
According to the characteristics of dust generation, we have developed special industrial vacuum cleaners for grinding and polishing, designed and installed special air hoods, selected high-efficiency filters in the filter bag configuration, and used pulse back-blow cleaning to remove dust. At the same time, installing a cyclone separator can control the source of the dust, and form an air ring around the dust to prevent the dust from overflowing and ensure that most of the dust is sucked into the vacuum cleaner, which can protect the operator and the surrounding environment to the greatest extent. Products are widely used in metallurgy, chemical, electronics, pharmaceutical, food, furniture, manufacturing, and other industries, dust removal and polishing workshops.
2. The filter bag selection method can be called the heart of the dust collector. The selection of the filter bag is very important, it directly affects the dust removal effect of the dust collector.
The filter bag is selected from the following aspects: temperature, humidity and chemical properties of the gas; particle size; dust concentration; filtering wind speed; dust cleaning method and other factors.
