Install the wind speed acceptance port in the room, and the wind pipe shall be used as the acceptance port. The horizontal pipe shall be installed at the place where the wind pipe turns 45 degrees or more every 6 meters. The wind speed in the pipeline should be ensured that the wind speed is above 20~23m/s, and there is no dust settling or accumulation in the pipeline. Generally, the dust is above 20m/s, and the metal dust such as aluminum and magnesium dust is above 23m/s.

The thickness of dust and slag on the tube wall of the explosion-proof dust collector shall not exceed 1 mm. The temperature, wind speed, and dust concentration monitoring devices are installed in the pipeline to monitor the temperature, wind speed, and dust concentration in the pipeline at any time according to the needs of the working conditions.

  1. Explosion-proof dust removal system

The dust concentration in the pipeline is controlled within the lower limit of dust explosion of 25%-50%. The inner pipe is larger than the outer pipe, and the strength of the outer pipe is greater than the strength of the dust collector body. The inlet and outlet pipe ports are equipped with a wind pressure difference monitoring and alarm device, which can also be installed at the inlet and outlet of the vacuum cleaner. The inlet pipeline of the outdoor dust collector cannot lead directly to the dust collector body. Install an explosion-proof valve at a suitable position and install an explosion-proof disk in diameter.

After calculation, when the explosion pressure difference reaches the predetermined value under the set explosion temperature, the explosion can be operated (broken or fall off). In order to prevent the vacuum cleaner body and pipeline equipment from being destroyed, it is necessary to configure enough explosion area to make the explosion pressure leak safely.

Explosion-proof dust collector

The vacuum rupture disc should be installed on the main body, and the directionality should avoid impact on the human body, dangerous objects, buildings, equipment, etc. The bursting disc of the pipe section must be installed in the radial direction of the intake main pipe. Explosive devices must lead the pressure discharge outlet to the outside of the building through a pressure discharge pipe. The explosion area of the pipe section must be greater than or equal to the section of the pipe section.

In terms of daily safety management, eye-catching safety signs are required on site, the operating procedures of the Explosion-proof dust removal system are affixed on site, the management of the person in charge is implemented, and safety inspections are carried out every day. In the event of an abnormality, the explosion-proof dust removal system must be stopped immediately run.
