Product introduction:

With the development of modern industry, the potential danger of dust explosion increases greatly. In the actual production, only use the explosion relief plate to relieve the explosion, and do not do a good job in explosion isolation. If dust explosion occurs in the dust collector, the pressure in the dust collector will increase, resulting in the flow of the air flow in the reverse dust collector, and the flame and pressure wave generated by the explosion will be transmitted to other connected equipment through the connected pipes, resulting in secondary or even more powerful explosion. The explosion-proof technology can prevent the explosion from spreading from the initial position to other process units, and avoid the occurrence of "secondary" explosion or system explosion accidents, so as to reduce the explosion disaster. Therefore, at least the inlet pipe of the precipitator usually needs to be explosion isolated.

As a passive device, dust explosion isolation valve can be used in areas 20, 21 and 22, as well as metal and non-metal dust of classst1 / ST2 / ST3.

The combination of flameproof valve and flameless explosion relief device can prevent pressure wave and flame from spreading to the production site of upstream workshop.
