Introduction to Bag Filters
Bag filters are essential components in various industrial and environmental applications. They are a type of filtration device that uses fabric filter bags to capture and remove solid particles from gas or liquid streams. In gas filtration, bag filters are commonly used in industries such as power generation, cement manufacturing, and metal processing to control air pollution by removing dust and particulate matter from exhaust gases. In liquid filtration, they are applied in water treatment, chemical processing, and food and beverage industries to purify liquids by removing suspended solids.
The principle of bag filters is relatively simple yet effective. The fluid containing the particles to be removed passes through the filter bags. The fabric of the bags traps the particles while allowing the clean fluid to pass through. Over time, as the particles accumulate on the surface of the filter bags, the pressure drop across the filter increases, and the bags need to be cleaned or replaced. This can be achieved through various methods such as mechanical shaking, reverse - air cleaning, or pulse - jet cleaning.
Now, let's take a look at the top 10 bag filter factories in China in 2026.
