Dust filter collector is the equipment that separate dust from flue gas. The bag filter is also known as the filter type dust collector, is a dry high efficiency dust collector, it is the use of fiber woven fabric bag filter element to capture dust particles in the solid particles of dust removal device. The principle of the role of dust particles in the filter cloth when the fiber due to inertial force and fiber collision was intercepted.
In the pulse and air box type pulse dust collector [1], the dust is attached to the outer surface of the filter bag. Dusty gas through the dust collector, the dust was trapped in the outer surface of the filter bag, and clean gas through the filter into the filter bag inside. The cage inside the bag is used to support the filter bag to prevent the bag from collapsing, and it helps to remove and redistribute the dust.
Dust bag fabric and design should try to pursue efficient filtration, easy dust stripping and durable effect. Dust bag selection is essential, it directly affects the dust collector dust removal effect, select the dust bag from the following aspects of choice: gas temperature, humidity and chemical, particle size, dust concentration, filtration wind speed, clear Dust and other factors.
The new environmental protection technology of the dust collector bag, especially a concave and convex folding dust bag. The cross-sectional shape of the inner frame and the outer frame is the shape of the surrounding concave and convex shape, the dust filter bag and the inner frame and the outer frame are integrally formed as radial folding closed cylinder structure. The utility model is a simple structure, easy to manufacture folding dust bag. In the same dust handling air volume under the premise of the folding dust bag effectively increase the filter area, so the dust collector volume reduction, saving space, saving equipment manufacturing investment. This bag filter has a high effect of cleaning dust and a good cleaning recoil effect, and is conducive to extend the life of dust bag.
We are filter bags manufacturer in China, we can produce all kinds of dust filter bags for clients from all over the world.
