The design method of the explosion-proof device of the dust removal equipment is to prevent the explosion of combustible dust in the equipment at the beginning, to prevent the explosion pressure from being too high. The explosion-proof device design of the dust removal equipment factory can control the dust removal equipment when the dust explosion pressure is greater than a certain pressure. The maximum pressure is below a certain program. In the event of dust explosion, it is also a good idea to install a pressure relief valve at the connection of the dust removal equipment. The blow-off valve device is also a good explosion-proof device.
The design of the explosion-proof device is as follows:
1: Calculation of the size of the pressure-exhaust area of the explosion-proof device. For high-density explosive dust removal equipment, the explosion-proof air exhaust area is too small to play a role, and the explosion-proof area design is too large to cause waste. ，一般在 1 ： 5 -1.50范围内，以粉尘爆炸的密度大小而设计。 The anti-explosive pressure relief is based on the ratio of the pressure relief area to the volume of the dust removal equipment . Generally , it is designed in the range of 1 : 5-1.50 with the density of dust explosion.
． 2: The pressure of the explosion-proof and pressure-exhausting device of the dust removal equipment is designed to be half the design pressure of the bag dust removal chamber, which is generally 5-7 . 压 力，最大不要超过10kPa压力。 5kP pressure , the maximum pressure should not exceed 10kPa. When the pressure value in the dust collector equipment reaches this index, the explosion-proof pressure-relief device should be opened in time for pressure relief.
3: Explosion-proof device design According to the calculated explosion-proof exhaust size area, install the explosion-proof device on the side of the dust removal equipment, and install it with a certain inclination angle. This is done so that the device can Reset with your own gravity to reduce air ingress.
In addition, in order to facilitate rapid pressure relief, there should be a large enough place, and the position of the explosion pressure relief port should be designed. For grinding and polishing dust removal equipment in the workshop, pipelines are usually connected to the outdoor for safety pressure relief.
4: The setting of the wet dust collector 's explosion-proof device is an important facility to provide dust-proof equipment and safe production for explosion-proof devices.
5: The design of the explosion-proof device of the dust removal equipment factory is generally located on the platform railing. An inspection platform and a railing are provided under the pressure relief device. This platform is used when checking the use of the explosion-proof device of the dust removal device. It should be closed in normal times. .
