Dust removal and explosion-proof equipment: flameless discharge device - dust explosion solution

　　1、 Dust removal and explosion-proof equipment: principle of flameless discharge device equipment：

▲ Schematic diagram of flameless venting device

The flameless release device consists of two parts, an explosion-proof board and a fire extinguishing module.

When a dust explosion occurs in a dust collector or dust collector, the flame is freely released during normal explosion pressure relief. When the equipment is installed indoors, the freely released explosion flames and shock waves can cause secondary explosions, resulting in greater losses. The flameless venting device is designed to protect personnel and equipment from dust explosion damage. When a dust explosion occurs, the explosion-proof plate (bursting disc) reacts to the rapid increase in detonation pressure and immediately opens to reduce the pressure. When the expanding fireball passes through the opened explosion-proof plate, it is intercepted by the fire extinguishing module. Stainless steel precision mesh supported by a frame plays a three-dimensional flame capture role, extinguishing flames and ensuring that they are not spread, thereby causing secondary or multiple explosions. The fire extinguishing module eliminates the flames of detonation, reduces the temperature of hot gases, and captures the combustion and unburned dust passing through the opened explosion-proof plate. At the same time, the pressure waves or noise generated by production equipment will also be minimized.

2、 Structural composition

Smoke free release devices are mainly used for indoor dust explosion protection, with no other operating costs, easy installation, and no need to install pressure relief pipes. It consists of an explosion-proof plate, a clamping base, and an explosion-proof box.

　　3、 The safety function and product advantages of explosion-proof devices：

1. Extinguishing Explosion Flames - No explosion flame can escape, and the explosion-proof device effectively prevents flames and heat, providing a safe place for equipment, buildings, and mobile personnel.

2. Retained explosion dust - captures process materials and eliminates potential harmful substances from entering the environment.

3. Control explosion pressure - absorb peak explosion pressure, protect personnel and the surrounding environment from damage caused by explosion pressure.

4. Control the explosion temperature - absorb the explosion fireball, so that the surrounding environment temperature hardly rises.

5. The whole machine is designed with stainless steel material, suitable for the food and pharmaceutical industries;

6. We can provide an online repair structure, which allows for the replacement of explosion-proof discs and the cleaning of fire-resistant components without the need to disassemble the interface.

　　4、 Technical features：

1. No open flame design can effectively prevent huge losses caused by secondary dust explosions

2. Customized processing according to customer requirements

3. Easy installation, simple hinge design and maintenance

4. Capture processed substances and eliminate potential harmful substances from entering the environment

5. Can be used in conjunction with explosion-proof valves

6. The flameless venting device does not require special maintenance. No need to link any electrical appliances

7. Blasting temperature: room temperature.
