What is a bin vent?
Bin vents are pulse jet style industrial dust collectors typically used to vent displaced air and harmful products in bins, silos or any other device or process that must contain or control dust particles. Top load design allows for easy changeouts on the clean air side of the collector.
How does a bin vent filter work?
How it Work. The dust ladden air enters the bin vent dust collector from the bottom. Once inside, the dust accumulates on the outer surface of the bag filter creating a surface cake. Reverse blasts of air are introduced at specific intervals cleaning the bag surface and sending the debris towards the open bottom.
What is a baghouse dust collector?
Baghouses are industrial dust collectors that use anywhere from 6 to 900 felt bags to filter dusty air produced by various manufacturing and processing applications.
How do you size a baghouse?
First calculate the total cloth area of your collector by calculating the total filter area of each filter (bag diameter x 3.14 x length ÷ 144 [for number of inches in a square foot] = filter cloth area) and then multiply that figure by the total number of bags in the collector.
What is the use of wet scrubber in the dust collection?
Dust collectors that use liquid are known as wet scrubbers. In these systems, the scrubbing liquid (usually water) comes into contact with a gas stream containing dust particles. Greater contact of the gas and liquid streams yields higher dust removal efficiency.
Can velocity in Bagfilters?
In this study, the effects of can velocity on the performance of a pilot-scale bag filter dust collector were examined. Test bag filters were made of polyester fabric and had a 156 mm diameter and a 3 m length. The cleaning interval decreased with the increased can velocity.
What does ESP stand for in dust collection?
An electrostatic precipitator (ESP) is a filterless device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit.
What is the use of baffles in the gravitational separators 1 point?
What is the use of baffles in the gravitational separators? Explanation: Baffles are placed in the direction of flow of flue gases. The dust particle strike down and settle. Heavier dust particles settle at the bottom by striking on to the baffles and lighter dust particles are exhaust into atmosphere.
What is a good air-to-cloth ratio?
Determining Air-to-Cloth Ratio Requirements For most laser cutting applications, manufacturers should look for an air-to-cloth ratio between 1:1 and 1.6:1. Processes that produce heavier particulate loads—thicker materials, continuous production or higher velocity—may need even lower ratios, between 0.5:1 and 0.75:1.
How do you calculate air to fabric ratio?
To calculate air-to-cloth ratio, take the amount of airflow (CFM) and divide that by the amount of filter area within your dust collector. For example, if you’re calculating for a cartridge collector, a typical range would be a 4:1 air to cloth ratio.
What is the basic principle of ESP?
Working Principle of ESP An ESP works on the principle of the corona discharge effect. A high DC voltage is applied across the two plates or electrodes. The negatively charged plate attracts the dust particles which are further attracted by the positively charged electrode by the process of Ionisation.
What should be used in a ventilation system?
(i) All air-conditioning or other ventilation ducts including framing thereof, shall be constructed of steel, aluminium, glass-fibre batt or mineral-wool batt or other approved material. (ii) All air-conditioning or other ventilation ducts shall be adequately supported.
Can a ventilation duct pass through a smoke stop?
Ductwork through smoke-stop or fire fighting lobbies Ventilation ducts should not pass through smoke-stop or fire fighting lobby. Where unavoidable, the part of the ventilation duct within the lobby shall be enclosed in construction with fire resistance rating at least equal to that of the elements of structure.
Can a ventilation duct be enclosed in masonry?
Where unavoidable, the part of the ventilation duct within the lobby shall be enclosed in construction with fire resistance rating at least equal to that of the elements of structure. Such construction shall be in masonry.
Can a ventilation duct pass through a fire fighting lobby?
Ductwork through smoke-stop or fire fighting lobbies Ventilation ducts should not pass through smoke-stop or fire fighting lobby. Where unavoidable, the part of the ventilation duct within the lobby shall be enclosed in construction with fire resistance rating at least equal to that of the elements of structure.
