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 high pressure blast of air is used to remove dust from the bag. The blast enters the top of the bag tube, temporarily ceasing the flow of dirty air. The shock of air causes a wave of expansion to travel down the fabric. The flexing of the bag shatters and discharges the dust cake.
The air compressor provides a large volume of high pressure air to a single or multiple "blast pots". Blast pots are pressurized, tank-like containers, filled with abrasive material, used to allow an adjustable amount of blasting grit into the main blasting line. The number of blast pots is dictated by the volume of air the compressor can provide.
The exhaust gasses of a blast furnace are generally cleaned in the dust collector – such as an inertial separator, a baghouse, or an electrostatic precipitator. Each type of dust collector has strengths and weaknesses – some collect fine particles, some coarse particles, some collect electrically charged particles.
It has a total of 124 collection points, 368 waste inlets, and 13 km of pipe. The system's daily collection capacity for dry waste, biowaste, paper, and recyclable cardboard comes to a combined total of 13 tonnes, and it became operational in 2012. In Bergen, Norway, a system covers most of the city center. [17] [18]
Blast dampers usually employ some type of blade held open with tension from a spring. The damper blades close automatically when pressure overcomes the resistance offered by the spring. Various models differ in the amount of blast protection (e.g. 1 bar/14.5 psi or lower amounts of protection) and whether they stay closed after the blast or ...
A jet blast deflector (JBD) or blast fence is a safety device that redirects the high energy exhaust from a jet engine to prevent damage and injury. The structure must be strong enough to withstand heat and high speed air streams as well as dust and debris carried by the turbulent air. [ 1 ]
