Dust removal equipment serves as the final filtration stage to control dust emissions from overflow, leakage, and venting of production equipment in enterprises.  Strict control is essential.

When enterprises discharge waste dust at the end of the production process, the dust can also be recycled and reused in production processes, such as in cement, carbon black, plastics, and non-ferrous metal smelting.

Currently, bag filters and cartridge filters offer high efficiency, are both dry dust collectors, and are known for their stable operation, durability, and wide range of applications.

Operating modes of cartridge dust collectors

Bag filter operating modes

The filter elements are made of different materials:

Bag-type dust collectors: Filter bag materials: polyester fiber, PET, PE, aramid, PP, PTFE, PPS, P84, FMS, polypropylene, etc.;

The types of filter materials used include: medium-low temperature range (90℃~140℃), medium-high temperature range (140℃~200℃), and high-temperature range (200℃~300℃).

Cartridge dust collectors: Filter cartridge materials: aramid, PTFE, PPS, polyester fiber, nanofiber, wood pulp paper, etc. The types of filter materials used are mainly in the medium-low temperature range (90℃~140℃).

Different Filtration Accuracy

When dust accumulation on the filter cartridges causes the pressure difference inside the dust collector to rise to the system's set value, the electromagnetic pulse valve opens, and compressed air is used to pulse-clean the filter cartridges.

Bag-type dust collectors generally have a filtration accuracy of 5-10 μm, with smaller accuracies achievable down to 1 μm;

Cartridge-type dust collectors generally have a filtration accuracy of 1-5 μm.

Different Space Requirements

Cartridge dust collectors can be installed in a modular fashion, have smaller dimensions and lighter weight, and can also be designed in combination with a fan, thus requiring less space.

Baghouse dust collectors are relatively larger in size and require more installation space.

Different Application Scopes

Both are suitable for dust control in various industrial fields, such as steel, metallurgy, building materials, and chemical industries.

However, there are also some differences in their application scopes.

Cartridge dust collectors are suitable for handling dust containing various fibers and ultrafine particles, such as in the crushing, screening, and batching processes of raw materials like limestone, cement, and ore in the metallurgical and building materials industries.

Baghouse dust collectors are suitable for handling various types of dust and flue gas, such as blast furnace gas, sintering flue gas, and lime kiln exhaust gas in the steel and chemical industries.

Therefore, when choosing a dust collector, we must first consider the actual site conditions, and then fully evaluate its manufacturing cost and subsequent operating costs. Only by considering all three factors together can we make an informed decision!
