Explosion-proof cleanout Casting
For producing dust or dust removal system inside, should be focused on eliminate flash point, improve the wind speed, or classification cut dust concentration.
For producing dust or dust removal system inside, should be focused on eliminate flash point, improve the wind speed, or classification cut dust concentration.
Here should be emphasized, some people often think a ventilation dust removal system, can eliminate the dust explosion hazard. This is wrong, for ventilation dust can only change environment dust concentration, and the dust explosion hazard transferred to dust removal system inside, so, in the dust removal system but is often form dust explosion hazards, such as dust removal system is not within the effective mining explosion-proof technology measures, only on ventilation dust is difficult to prevent dust explosion. This is the scene of the accident at home and abroad dust explosion proof point. Because in the dust removal system in basic dust concentration in the explosion limit inside, is a relatively closed space, all kinds of impact, friction, electrostatic, flame and smoldering and ignition probability high.
In this condition and environment, change the dust concentration is not objective, is not the economy, we can only improve operating wind speed, negative pressure work, the explosion-proof fans and explosion-proof motor, eliminate flash point, in the system used in flame retardant and antistatic materials, has a good grounding and equipped with drain detonation and explosion-proof cleanout, and is equipped with pressure and temperature danger forecasting and monitoring system, when the system risks occur within will automatically stop host work, each explosion explosion suppression system automatic work, the production equipment start 10 minutes before start dust removal system, the production equipment stop working after 10 minutes to stop the dust removal system work.
