Dust filtration and Performance

Filtration and performance of today's society because dust pollution is serious kinds of bad weather, such as fog and haze, and this time the popular environmental protection equipment, such as dust removal equipment, 巩义义 Lee Machinery Factory specializes in the development of dust production, today, Let's talk about the precipitator filtration and performance. Selection filtering baghouse filter can be divided into four categories: upper intake within the filter type; upper intake external filter type; within the next intake filter type; the next intake external filter type. Due to the use of the upper intake, falling direction of the same gray dust net gas flow, the dust is easy to produce reflux, now rarely use this mode. The lower part of the intake mode, inner filter bag filter bag leak detection system is more difficult and less use; outer filter bag hanging systems easily, replace the bag is simple, easy, basic workers not touching the dirt, labor conditions greatly improved. Performance parameters determining the collection efficiency 1. fiberglass bag filter efficiency level depends mainly on the dust filter and dust bag surface layer established in different structural forms of cloth, the filtration efficiency is also different. Secondly, also with the cleaning method and cleaning ability. High pulse jet bag filter cleaning ability, and at the time a dense fleece or felt, as a bag filter, although not entirely rely on the dust layer to maintain high efficiency, but efficiency is not the same in different media. Using felt made bag, high collection efficiency, and stability. The use of Nepalese wool blend made of 208 polyester flannel bag, the dust precipitator run phenomenon occurs, which is due to high cleaning capacity, undermining the established filter dust layer caused. In addition, the bag with the long-term use of the new production, the collection efficiency is not the same. Generally felt bag new efficiency up to 99.99%, 208 flannel dust bag up 99.5%. Dust bag during use due to mechanical friction and dust erosion frame, so wear off hair loss, and suture repair of poor quality and other factors reduce efficiency. Therefore, in the calculation of collection efficiency, efficiency can not be considered under the new bag. 2. The pulse jet blowing three elements of the three elements namely injection pressure, injection time and the injection cycle. In the injection mechanism of electromagnetic pulse valve diameter, venturi tube structure, lower injection hole diameter and number of holes, bag diameter and length has been set, the three elements of blowing dust are the main factors affecting performance. In the design selection and the actual operation, handle the relationship between the three is to ensure the normal operation of critical filter baghouse increasingly wide range of applications. A variety of bag filter type, pulse jet bag filter most widely used in the metallurgical industry.
