Highlights of Bag Dust Collectors in the Grain and Feed Industry:
1. High dust removal efficiency: Multiple dust removal methods are available, with a dust removal efficiency of over 99%;
2. Wide applicability: Different components are matched to form different specifications, designed to be flexible;
3. Satisfy multiple working conditions: can be matched with normal temperature, medium temperature, and high temperature filter materials to meet various working conditions requirements;
Suggestion reminder:
1. The selection of bag filters for grain and feed factories is a crucial step in meeting process requirements, but the design of the entire air network cannot be ignored. The design of the air network directly affects the energy consumption, working capacity, and dust removal efficiency of the dust removal system.
2. For dust with an inlet concentration of over 15g/m ³, it is generally necessary to pre purify or reduce the filtration wind speed of the dust collector.
3. At room temperature, for dust particles with a particle size of ≤ 1 micron or high moisture content, coated filter media can be used first. It is not practical for dust particles with larger particle sizes and significant differences in particle size distribution. When selecting membrane filter media, it is recommended to filter at a speed of less than or equal to 2m/min, or even less than 1m/min.
4. The conductivity and explosiveness of dust cannot be ignored. The inorganic content in grain and feed dust is relatively high, accounting for more than average, and the average particle size is also large. Based on some past accidents, the explosive nature of these dust cannot be ignored. Strictly speaking, the selection of bag filter is a mistake. A bag filter system is composed of multiple independent system configurations with different technologies, which need to be designed separately for different dust, processing capacity, and production processes. Directly selecting the corresponding model for processing air volume, blindly "selecting" in dust collector applications often leads to various accidents.
