With myriads of dust collection systems doing the rounds in markets, the choice of Baghouse Filters can be quite an affair. Even if you do zero in on a brand, there are other factors to be considered like the size of the filter, the type of the filter, the chemistry behind the process, etc. Therefore, to choose your air pollution control device, you would need to know about a few requisites. Your filter should consist of the right parts to bear the environment in which it is supposed to function. These are few tips which should be kept in mind before purchasing the right kind of Baghouse Filters. A few of them are listed below:
The Inlet Temperature:
The inlet temperature of the Baghouse Filters should be equipped to withstand extreme temperatures. You should opt for a baghouse which is flexible with temperature ranges and can handle the dust at any temperature before it even makes way to the inlet of the unit. You can also choose a certain baghouse where the temperature is never the major concern and can smoothly function without creating much worry in the minds of the owner.
Knowing the Science Behind the Cleaning Process:
While the proper knowledge of the functioning of Baghouse Filters could be alien to you, it is not a rocket science. A simple understanding can go a long way in determining the right cleaning device for you. The fabric filter should be well devised to eradicate all the dirt from the acidic/active ecosystem inside your commercial space, and hence, Teflon is the most appropriate choice to work as a fabric filter for the dust collector. Teflon’s chemical constitution render it to be the fittest to remove dirt under extreme conditions and are chemically averse to dry and moist heat degradation.
Its low friction capacities provide for impeccable cake release. Teflon is the most popular choice for fabric filters used in boilers, incinerators, carbon black plants and soil correction systems as it can bear chemically active particles up to the temperature of 500-degree Fahrenheit.
Polyester ranks as the close second in favorites in fabric filter material as it is often called to be the workhorse of the industry. Polyester can be used in any filter fabric in a baghouse system which works in various ambient conditions or to 270-degree Fahrenheit. They have outstanding robustness and economic benefits. Polyester also deserves special mention for a number of features such as energy absorption and its ready endurance to most oxidizing agents and mineral acids.
It is important to understand the chemical composition of the gas stream, whether the gas is of a Sulphur compound, a chloride compound or just has high oxygen in proportion.
Moisture Condensation:
The possibility of the presence of moisture condensation in the Baghouse Filters augments the performance of your dust collection system. Therefore, equally pivotal is the selection of fabric and the finish of the moisture condensation in the gas stream. Not operating in the right moisture level or not having a fabric filter well-equipped to handle the varying moisture levels in the air can affect the chemical compounds present and either corrode or lead to chemical attacks to the fabric filters. Furthermore, moisture can also lead to cohesion and accumulation of particles on the surface of the filter, thereby obstructing air flow path and causing erroneous pressure levels and drastic pressure changes.
So, the proper grasp of your system’s moisture level in the gas stream will help you choose the proper Baghouse Filters by considering both the media selection and the possible requirement of a specialized treatment mechanism.
