Industrial production consumes a lot of energy and emits pollutants such as smoke and dust, which have a negative impact on the ecological environment. The filter is an effective tool to remove dust and other contaminants. Due to the decline in coal quality, the emission requirements of vacuum cleaners are becoming higher and higher. The mixture of dust and oxygen is prone to explosion, and Industrial explosion-proof dust vacuum cleaners are required.

The characteristics of the dust explosion in the processing of various materials.

The dust combustion speed or explosion pressure rises faster than the gas explosion, but the combustion time is long and the energy generated is large, so the combustion and the high degree of combustion form an explosion.

Compared with flammable gas explosions, dust explosions are more complicated. Typically, combustible dust is suspended in the air and forms a dust cloud within the explosive concentration range. Under the action of the fire source, the dust that first contacts is ignited first to form a small fireball. The fireball releases a large amount of heat by burning to heat the surrounding area. The combustible dust then catches fire and burns. In this environment, the fireball expands rapidly and eventually explodes.

In order to ensure the safe production of the system, industrial explosion-proof dust vacuum cleaners are designed, which mainly include explosion-proof safety valves, explosion-proof diaphragms, heavy hammer safety valves and shrapnel-type leakage devices.

The industrial Explosion-proof dust vacuum cleaner suction device consists of a down pipe, an air volume control valve and a rectangular suction pipe. In the design of the suction pipe, the degree of negative pressure resistance of the pipe wall must be considered comprehensively. The pipe wind speed control valve can As a common part of the factory, the thickness of the air plate of the general vacuum cleaner should be controlled at about 5mm, and the wind speed of the pipe wall should effectively reduce the dust concentration in the pipe to avoid dust accumulation

In the Dust explosion-proof 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 prevent dust explosions.
