A blast gate is a gate valve used to focus a dust collection system's vacuum pressure for maximum dust (or other material) extraction at the desired location. Blast gates are positioned near individual pieces of machinery and operate by being closed by default, blocking air flow.
A dust collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas. Designed to handle high-volume dust loads, a dust collector system consists of a blower, dust filter, a filter-cleaning system, and a dust receptacle or dust removal system.
A video on cleaning dust from workers' clothing. Occupational dust exposure occurs when small particles are generated at the workplace through the disturbance/agitation of rock/mineral, dry grain, timber, fiber, or other material. When these small particles become suspended in the air, they can pose a risk to the health of those who breath in ...
The vacuum created inside the dust collector holds the valve closed, allowing a head of material to build up above the trickle valve. Once the pressure of the material equals the negative pressure of the system, the valve is forced open and a trickle of material will begin flowing from the valve at the same rate it is collected.
Dust-laden gas or air enters the baghouse through hoppers and is directed into the baghouse compartment. The gas is drawn through the bags, either on the inside or the outside depending on cleaning method, and a layer of dust accumulates on the filter media surface until air can no longer move through it.
The Spot With The Most Dust Under my bed. When I pulled my bed away from the wall to clear the space for the painters, I noticed copious amounts of dust on the carpet and a boatload of dust ...
Smartwatches are a hot-ticket gift over the holidays, but a new study might have you rethink how you strap the device to your wrist in the future.
The system can be flushed with an inert gas to reduce the concentration of oxygen so that when the flammable gas is admitted, an ignitable mixture cannot form. In NFPA 56, [1] this is known as purge-into-service. In combustion engineering terms, the admission of inert gas dilutes the oxygen below the limiting oxygen concentration.
