Industrial production consumes a lot of energy, and the emitted smoke, dust, and other pollutants seriously affect the ecological environment. The filter is an effective tool to remove dust and other contaminants. The quality of coal combustion is low, and the amount of smoke and dust is large. The mixture of smoke and oxygen is prone to explosion. Industrial dust explosion-proof equipment is required.

Explosive characteristics of dust from processing different materials.

The burning speed or explosion pressure rises faster than the gas, but the burning time is long and the production capacity is large, so the burning degree is high, forming a deflagration.

Compared with flammable gas, dust explosion is complicated. Under normal circumstances, combustible dust is suspended in the air and forms a dust cloud within the explosive concentration range. The dust in contact with it is ignited first, and a small fireball is formed under the action of the fire source, which releases a large amount of heat when burned, making the surrounding combustible dust When heated, combustion occurs, the dust expands rapidly, and finally explodes.

In order to ensure the safe production of the system, industrial devices for Explosion-proof dust removal are designed, which mainly include explosion-proof safety valves, explosion-proof membranes, heavy hammer safety valves and oil leakage devices.

The suction device of dust explosion-proof equipment is composed of a down pipe, an air volume control valve and a rectangular suction pipe. When designing the suction pipe, the degree of negative pressure resistance of the pipe wall should be comprehensively considered. The pipe wall wind speed control valve can be used as a pipe, and the air plate of a general vacuum cleaner The thickness should be controlled within 5mm, and the pipe wall wind speed should be able to effectively reduce the dust concentration on the pipe wall and avoid dust accumulation.

In the Dust explosion-proof equipment system, automatic design and detection of alarm interlocking functions are indispensable. When the system finds potential hazards nearby, the alarm information can be transmitted to the mobile port through the central control system to achieve dust collection and explosion protection.
