1. Round bag filter in Figure 1-8. b, c, d, e are round bag filter, bag shape is cylindrical diameter is generally 120 ~ 300mm, maximum of 600mm, height of 2 to 3 seconds, there are more than 10m, due to the round bag The support frame and the connection is relatively simple, easy cleaning, maintenance and management is also more convenient, it is widely used. 2. A is a flat flat bag filter bag filter bag shape is a flat shape, thickness and bag space for 25 ~ 50mm height of 0.6 ~ 1.2m, depth of 300 ~ 500mm. The biggest advantage is the unit volume filtration area, but because of cleaning, maintenance, changing bag is more complex, it is restricted application. (B) the direction of filtration by filtering direction classification classification, can be divided into inner and outer filter dust collector filter dust collector. 1. The inner filter type bag filter in Figure 1-8. c, e within the bag-type dust collector, dust-laden air from the outside of the bag measured flows, dust deposited on the inner surface of the bag, the advantage of an external bag for clean gas, ease of maintenance and change the bag, and even that is non-stop can overhaul. General mechanical vibration, anti-hair cleaning methods, such as multi-use within the filter form. 2. The external filter type bag filter in Figure 1-8. b, d outer bag type dust collector, dust-laden air from the outside of the bag to flow inside the dust deposited on the outer surface of the bag, the bag support frame to be set up, so wear a larger bag. Pulse-jet, rotary cleaning and other cleaning method to use more outside the filter form. Sling-type dust collector filter is mostly in the form. (C) by the position of the air intake air intake position classification by classification, can be divided into the wind under the baghouse and motivated wind baghouse. 1. Under the baghouse inlet Figure 1-8 b, c for the next intake air baghouse dust precipitator gases enter the lower air flow from bottom to top, large particles directly into the hopper reduced bag wear and extend the cleaning interval, but because the air flow direction and dust falling in the opposite direction, easy to take out the part of the fine dust, reducing the cleaning effect, increasing the resistance. Under the precipitator inlet simple structure, low cost, a wider application. 2. motivated wind belt filter in Figure 1-8. d, e is motivated wind baghouse, dusty gas inlet located in the upper dust, dust settlement consistent with the direction of flow, help settling dust collection efficiency has increased, resistance of the device can also be reduced by 15 to 30%. Second, according to the pressure inside the precipitator dust classification by pressure within the classification can be divided into inhalable dust and pressed into the dust collector. (A) push-push type dust collector filter, fan settings before precipitator dust in the positive pressure of work, due to the dust and gas to go through the fans, for the fans wear more serious, and therefore does not apply to high concentration, coarse, high hardness, strong corrosive dust. (B) the inhaled dust inhaled dust, after the fan and filter settings, dust in the vacuum state work, due to dust and gas purification after entering the fan, so the fan wear small, this approach uses more. Third, by cleaning method classified baghouse cleaning method is to determine the line can be an important factor, it is the collection efficiency, pressure drop, filtration velocity and bag life are relationships. Recently issued by the State baghouse classification criteria are categorized according to cleaning methods. In accordance with the cleaning method, baghouse can be divided into five categories: 28 species (two) bag filter bag filter is cleaning method named classification and structural features combined with the most representative named . Nomenclature baghouse unit is also the same. For more information you can call our service hotline, you can also visit our official website for more information www.rdlhbsb.com!
