How to choose explosion-proof dust collectors in the aluminum powder industry

Aluminum powder explosive dust can easily explode or burn when encountering sparks or static electricity at a certain concentration. The most critical factor in aluminum powder blasting is the concentration of aluminum powder, and the most effective method of controlling aluminum powder blasting is to manipulate the concentration of aluminum powder. To ensure safe operation, a gravity type active blasting door is also installed at the critical position of the dust collector. This equipment is usually depicted at the top of the shot blasting chamber and dust removal pipeline, in areas with dense dust. After accurate calculation, the door can be opened automatically at the beginning of the blasting to release the blasting pressure and prevent damage to equipment and personnel.  
After unloading, the door is actively closed by gravity, and the Ingmar pulse dust collector controls the concentration of aluminum powder. As long as the dust collector has excellent working conditions and good dust removal effects, the aluminum powder concentration of the entire cleaning machine equipment will not increase. Therefore, ensuring the outstanding dust removal function of the dust removal equipment is the key to its normal operation. The effectiveness of dust removal depends primarily on the filtering material, and when the filtering material becomes blocked, the dust removal effect will greatly decrease. When the ventilation and filtration conditions of the filtered data are excellent, the pressure difference between the static pressure chamber and the dynamic pressure chamber of the dust collector will remain stable within a fixed range. Therefore, controlling the pressure difference of the dust collector is the most useful method to control its operating conditions. When the dust collector is blocked for a period of time, the pressure difference detected by the instrument will change. When the detection value exceeds the set upper and lower limits, the pressure difference controller will operate the cleaning organization of the filter bag of the dust collector, such as shaking or blowing back the organization to remove the dust on the surface of the filter material of the dust collector, to ensure excellent working conditions for dust removal.  
When the active cleaning still cannot meet the demand, the differential pressure controller will operate the alarm and control the equipment to actively close to prevent accidents.  
The design of the explosion-proof dust collector system's explosion-proof device should be based on the physical and chemical properties of the processed materials, dust explosion index, operating temperature and pressure, pressure fluctuations during production, whether there are reverse pressure changes, required opening pressure, explosion-proof port size, enclosure volume and its aspect ratio, special and usual operating conditions, maximum allowable explosion-proof pressure, enclosure material, relevant explosion-proof membrane strength, relevant explosion-proof frame material, total required pressure relief area, installation conditions and dimensions, etc. The explosion-proof device should meet the following requirements:
(1) There is accurate opening pressure
(2) The starting inertia is small, and generally the explosive closure does not exceed 100PA
(3) The opening time should be as short as possible, and the explosion vent should not be blocked
(4) By avoiding factors such as ice, snow, debris coverage, and corrosion, the actual opening pressure value increases
(5) At the sealing point of the dust collector vent door, weak heat is used to eliminate freezing and avoid increasing the opening pressure
(6) Avoiding the harm of explosive device fragments to personnel and equipment
(7) To prevent negative pressure inside the enclosure caused by the closure of the venting door after venting, which could damage the enclosure
(8) To prevent excessive airflow from passing through the pressure relief port, pull open the explosion-proof cover
(9) The pressure relief port of the dust collector should be equipped with a safety net to prevent people from accidentally falling in. The mesh should be larger to avoid reducing the explosion area
