The flameless release device consists of two parts, an explosion-proof board and a fire extinguishing module. The explosion-proof plate responds 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 with frame support plays a three-dimensional flame capture role in extinguishing flames. 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.

There are three main ways to prevent dust explosions: explosion venting, explosion isolation, and explosion suppression

Explosion relief: By using a pressure relief device to release the explosion in advance, the equipment is protected from damage.

Explosion proof: A type of explosion-proof valve is used to block explosions and prevent flames from spreading.

Explosion suppression: Firstly, the detection device detects the initial spark formed, and then feedback activates the fire extinguishing device to instantly extinguish the fire and prevent the occurrence of an explosion.

Five safety functions of flameless explosion prevention and pressure relief device for dust removal equipment:

Flame Capture - No flame can escape, providing a safe operating environment.

Eliminate the harm of external secondary ignition and its potential continuous explosion to the equipment.

Dust retention - capturing processed substances and eliminating potential harmful substances from entering the environment.

Eliminate high-pressure buffering explosion pressure peaks, protect personnel and the surrounding environment, including buildings, from the threat of explosion pressure.

Temperature control - absorbs fireballs, but the surrounding environment temperature hardly rises.

Working Principle:

When the flame passes through the mesh flame retardant element, the flame retardant element exchanges heat with the flame, quickly cooling the high-temperature flame, releasing pressure and smoke, ensuring that the flame is not spread, thereby causing secondary or multiple explosions. At the same time, the pressure waves or noise generated by the production equipment will also be reduced. In industrial production, the combination of flameless venting devices and explosion-proof valves not only effectively prevents pressure waves and flames from spreading to the production site of upstream workshops, but also suppresses the occurrence of secondary explosion accidents, reduces property losses, and protects personnel safety..

A large amount of solid dust is generated in the industrial production process, which seriously affects the working environment and workers' health. When mixed with air during processing or storage operations, explosion can cause ignition of combustible gases, mist or dust. Rapid pressure rise occurs in a sealed structure, and if there is not enough strength to withstand the burst pressure, it will cause significant losses and casualties. When the dust removal equipment is located indoors and only uses the venting plate to vent, the flames and pressure waves generated by the explosion will be directly released into the work area, which may cause secondary accidents and seriously affect the working environment and worker safety. Therefore, it is very necessary to install flameless venting products in the powder system of the production workshop.

Composition of flameless explosive device:

The flameless explosion-proof device of the dust collector consists of a flame extinguishing template, explosion-proof plates, explosion-proof junction boxes, and clamps.

The explosion-proof core is formed by connecting the shell and the upper cover with square tubes, forming a extinguishing module component. When the plate reacts to the rapidly accumulating explosion pressure and opens to release the pressure, it is intercepted by the extinguishing module as the forming fireball passes through the opened plate. The stainless steel precision mesh screen installed in the stainless steel frame serves as a three-dimensional flame arrester to extinguish flames. The extinguishing module suppresses the flames and hot gases of detonation, as well as the combustion and unburned dust by opening the explosion-proof door. The three-dimensional mesh design can serve as a heat sink, preventing explosions in the middle section and absorbing pressure waves and dust released by the explosion.

Although the temperature of the fireball from a dust explosion can easily reach 1000 ° C, the large surface area of the extinguishing module can quickly cool and maintain at 100 ° C. Below the temperature of C. This makes the temperature changes around the system negligible. Due to its ability to extinguish flames, contain dust, and control pressure and temperature, flameless pressure relief devices can be used in any indoor location where explosion impact needs to be avoided.

Dust removal equipment flameless explosion and dust explosion-proof pressure relief device Application fields:

Production workshops for artificial boards, wood, and furniture.

The environment of fibers, shavings, and dust generated during the movement of objects such as metals and sand.

The spark environment generated during the operation of high load equipment.

Enterprises that generate high dust environments such as tobacco, chemical, textile, food, feed, metallurgy, leather, rubber processing, etc.

Dust explosion requires five elements, and when these five elements coexist, there is a possibility of explosion occurring. The five elements are as follows: oxygen; Combustible dust; Fire source; Dust cloud; confined space

Dust explosion is accompanied by strong shock waves and flames. Due to the lack of pressure resistance of the equipment, it will be damaged during the explosion, resulting in the risk of secondary or multiple explosions. So we are required to pay attention to dust explosion protection.

In order to prevent equipment from generating dust explosions or to avoid greater harm in the event of dust explosions, explosion-proof pressure relief equipment is particularly important.

Explosion venting is one of the commonly used and effective methods of explosion protection; Release pressure during potential industrial explosions and provide a well-designed pressure release! Flameless discharge flame arrester device
