Dust Collector / Bag Houses

FILTECH Pollution Control System & Dust Collection/Extraction system is generally comprised of Dust extracting, Bag filter & Ducting. We generally design the system based on the data of Packing Machines. Following are the description of the equipment’s to be used in the system

Bag filter:
The bag filter is essentially a system containing a filter fabric of some kind that removes dust and particulate from a gas stream. The cleaned gas can be vented to the atmosphere; the dust may be a product such as material dust, carbon black, fumes from the furnace, fly ash from a boiler burning coal. Bag filters are among the oldest and most widely applied particulate emission control devices. The clean air emerges from one side of the medium while the dust is collected onto the bottom. The pulsejet mechanism of compressed air facilities is continuous cyclic cleaning of bag dust cake.

ID Fan:
These are employed for air containing dust or particles, fibers, flakes, and having a higher temperature than ambient. Usually offered in single inlet styled fans are moderately efficient and useful for dust collection, drafting, and exhaust/pollution control duties. Impellers are radial tipped or backward inclined bladed type having flat of airfoil designs, with closed or open constructions. The p-v characteristic is flatter and blowers are designed for long hard duties.

Online Spark Arrestor:
A spark arrester is an online device that prevents the emission of flammable debris from combustion sources, such as internal, fireplaces, and wood-burning stoves. Spark arresters play a critical role in the prevention of filter media fire and ignition and explosive atmospheres in the baghouse. As such, their use is required in the steel industry due to hot iron chips.

Cyclones (or centrifugal collectors) create a ‘cyclonic’ or centrifugal force, similar to water going down a drain, to separate dust from the polluted air stream. The centrifugal force is created when dust-filled air enters the top of the cylindrical collector at an angle and is spun rapidly downward in a vortex (similar to a whirlpool action). As the airflow moves circularly downward, heavier dust particles are thrown against the walls of the collector, collect, and slide down into the hopper.
