Choosing a high-quality dust bag is just as important as your purchase of other production equipment. The right choice of high-quality dust bag can collect dust particles in the air, improve air quality and prevent the accumulation of combustible dust.
Especially in industrial production, the right dust bag can ensure a safe and healthy working environment, which will improve the productivity of employees. On the other hand, a proper bag can reduce the downtime of bag filter maintenance and maximize the filtration efficiency of the dust collector.
What is a bag filter?
A bag filter is a device that separates dust from flue gas. The bag filter, also known as the bag filter, is a dry high-efficiency dust collector, which is a dust removal device that uses a bag filter element made of fiber fabric to capture solid particles in dust-containing gases. The principle of action is that the dust particles are intercepted by the inertial force when they collide with the fibers when winding the filter cloth fibers. The baghouse is very efficient and is able to collect 99 percent of the air and airflow through it9% more particles.
How to Choose the Best Dust Bag for Your Duster Collector.
The first step in choosing the right dust bag is to understand the process conditions and requirements of the equipment. and the particle diameter and particulate matter characteristics of the bag through the dusting cloth.
Choosing the right type of bag is related to the continuous operating temperature of the airflow at the inlet of the baghouse.
If the ambient operating temperature does not exceed 80°C at any time, any type of dust bag may be considered. However, as the operating temperature continues to rise, a specific heat-resistant fiber material must be selected. PVC, nylon, cotton, polypropylene, PTFE, and fiberglass are all common materials used in baghouses.
It is important to understand the heat resistance of the material. For example, cotton can withstand heat up to 85°C, polyester can withstand heat up to 150°C, and PTFE can withstand heat up to 260°C. Any significant moisture or chemical fumes in the gas stream also need to take into account the type of material used.
Choosing a bag design for your baghouse depends on the efficiency of the collector itself. It may require a traditional woven fabric design or a non-woven design such as needle felt. Pulse baghouses allow the use of heavier, denser, and even stiffer needle felt bags, while rapping dusters can use lighter woven fabrics. In contrast, in cases where filtration is less required, backflush dust collectors use lightweight, flexible, and smooth woven fabric materials.
