1、 The filtration accuracy of filter cartridge dust collector and bag dust collector is different

1. The dust removal bag of the bag filter is made of soft filter material sewn together. The filter material variety is long polyester fiber and its post-treatment raw materials are mostly single-layer general industrial polyester cloth. The filtration accuracy is mainly determined by the matching filter cloth bag. Generally, the filtration accuracy of a single layer needle felt filter bag is 5-10m, but after composite treatment, it can achieve a small accuracy of 1m.
2. The filter cartridge dust collector uses a folded arrangement of filter cartridge filter materials to form a cylindrical shape. Generally, the filtration accuracy of conventional polyester fiber filter materials is 1-5m, but after PTFE coating treatment, it can reach 0.3m. Some special treatment processes can achieve a filtration accuracy of 0.1m, which can meet the H13 filtration standard

2、 The filtering materials used in filter cartridge dust collectors and bag dust collectors are different

1. Bag filter is a type of dry filtration equipment for dusty gases, generally used in situations containing dry, fine, and non fibrous dust. Its filtration data often includes polyester, PE, NOM, polypropylene, aramid, PP, PPS, P84, PTFE, etc. PPS filter material has good acid and alkali resistance, and can operate continuously at a temperature of 190 degrees Celsius. It can withstand a high temperature of 232 degrees Celsius instantly (without the influence of other chemical components); The operating temperature of P84 needle punched felt is 220 degrees, with a maximum temperature of 260 degrees.
2. The filter cartridge dust collector uses a new type of filtering material, which is commonly made of polyester fiber, nanofiber, wood pulp paper, etc. The surface is treated with PTFE, flame retardant, anti-static, oil proof and waterproof processes. The filtering material is folded into a wrinkled shape, with a large filtering area, high dust removal efficiency, low resistance, and good performance.

3、 The application and protection costs of filter cartridge dust collectors and bag dust collectors are different
In terms of equipment cost, the cost of a typical filter cartridge dust collector is about 30-50% higher than that of a typical bag filter. This is mainly due to:

1. The cost of a filter cartridge dust collector is much higher than that of a bag filter;

2. Generally, a filter cartridge dust collector is equipped with an electromagnetic valve for each filter cartridge, while a bag dust collector is usually equipped with an electromagnetic valve in one row or row. The electromagnetic valve and control cost of the filter cartridge dust collector will be relatively high;

3. The general filter cartridge dust collector is applied in high-precision filtration situations. Due to its small volume, it is generally manufactured using processes such as cold rolled steel plate laser cutting, welding, fine polishing, acid pickling and phosphating, electrostatic spraying, and high-temperature baking. The product has high requirements for appearance and durability, and although the volume is reduced, the sheet metal cost is also not low.

4、 The volume size of filter cartridge dust collector and bag dust collector is also different
If under the same filtering area conditions, the filter cartridge dust collector is at least one-third smaller than the bag dust collector, the root cause is that the filtering area difference between a single scale bag and filter cartridge is relatively large. For example, when comparing a set of 169 m2 bag dust collector components with a filtering area of 169 m2 and a filter cartridge dust collector with a filtering area of 180 m2, the length and width scale bag dust collector is twice as large, and the height scale is also twice as large.
