The main points of selection and management of general dryers are to dry aluminum-magnesium dust. Choose a dry-type external filter pulse bag Explosion-proof vacuum cleaner and operate under negative pressure. The vacuum cleaner is made of welded steel. Various combustible dust cannot be used with the same dust collector at the same time, and a more Professional explosion-proof dust collector is required.

Requirements for the use of explosion-proof vacuum cleaners.

The dust filter cartridge has an anti-static function, and the metal material part connected with the filter cartridge is anti-static treated with an electrostatic cross method.

The pulsation solenoid valve uses an explosion-proof solenoid valve to monitor the injection pressure and adjust the injection frequency according to the injection effect. After dust is removed from the surface of the filter bag in the dust collection box, the remaining thickness shall not exceed 1 mm.

The main body of the dust collector should be equipped with explosion-proof devices that meet the explosion-proof requirements and inlet and outlet pressure difference monitoring and alarm devices. All explosion-proof dust collector safety devices should be interlocked with the system protection.

The temperature control of the dust collector is required. The vacuum ash hopper is arc-treated, and the design angle of the ash hopper is greater than 70°.

According to the degree of danger of dust explosion, a powder or spray suppression system is added to the dust collector. Use the detector to detect the rapid rise of explosion pressure or temperature, start the explosion system, and quickly spray fire extinguishing agent (inert gas, sodium bicarbonate powder) or water source through the explosion system or spray system to achieve the effect of Prevent dust explosion.

Requirements for explosion-proof dust collectors.

The vacuum cleaner must meet four requirements. The second is the connection between the air inlet and the pipeline where sparks are likely to be generated during work, and spark detection and spark extinguishing devices are installed according to the situation; the third is to prevent the inhalation of iron pieces, screws and other devices that are prone to sparks; the fourth is that the air inlet can meet the wind speed of more than 1m /s requirements.
