Principle and Structure of Cloth Dust Collector Bags

With the development of bag dust removal skills and increasing environmental protection requirements, the use of cloth dust collector bags has become more and more common. At present, dust collectors equipped with cloth dust collector bags can be used to deal with high temperature, high humidity, adhesion, explosion, and abrasion, and can even filter the air containing ultra-fine dust.

1. The principle of cloth dust collector bags

The cloth dust collector bags can be called the heart of the bag type dust collectors, generally called the dust collector bag or the dust filter bag. The dust bag is a key part of the cloth dust collector bags in the process of operation. It is usually a cylindrical vertical hanging in the dust collector. The cloth dust collector bag is a device to separate dust from the flue gas. The cloth dust collector bag has also become a filter type dust collector. It is a dry type dust collector, which is a dust removal device that uses a bag filter element made of fiber woven fabric to trap solid particles in the dust-containing gas. The principle of action is that dust particles are intercepted by collision with the fibers due to inertial force when they wind around the fibers of the cloth dust collector bags.

2. The structure of the cloth dust collector bags

In the lower area of the cloth dust collector bags and the part opposite to the outlet, the air flow will be stagnant. Due to the heat dissipation and cooling of the box wall, it is easy to condense. In order to reduce the wall heat dissipation, it is designed to be a special way of installing a rib structure on the side of the box body. The environmentally friendly non-asbestos gaskets and sealing materials used on the box body should be selected from materials that can withstand the set temperature.

3. The use of cloth dust collector bags

The pros and cons of the cloth dust collector and industrial dust bag dust removal effect are related to many factors, but mainly depend on the filter material. It is flexible to use, and the disposal air volume can range from hundreds of cubic meters per hour to hundreds of thousands of cubic meters per hour. It can be used as a small unit directly installed indoors and near the machine tool, or it can be made into a large dust collection room, that is, a "bag house". The filter material of the cloth dust collector is a cloth or felt woven from constituent fibers, natural fibers or glass fibers. According to the design of the cloth dust collector bags, the cloth or felt is sewn into a cylindrical or flat filter bag.
