The fabric design of dust filter bags should prioritize high efficiency filtration, easy dust stripping, and durability. Dust filter bags are crucial components in dust collectors. The selection of dust filter bags depends on factors such as the nature of the dust, dust cleaning method, and dust gas composition, thus requiring different considerations.

1. According to the requirements of the working conditions to choose the cost performance of the appropriate dust filter bags.

1.1 Gas temperature. Gas temperature below 130 ℃ choose room temperature dust filter bag, temperature between 130 ℃ -260 ℃ choose high temperature dust filter bag.

1.2  Gas humidity. Dust-containing gas is divided into three states according to the relative humidity: dry gas (relative humidity below 30%), general state (relative humidity between 30%-80%) and high humidity gas (relative humidity of 80% or more). When the gas humidity is high, you should choose a laminated waterproof cloth bag.

1.3 The chemical nature of the gas. In a variety of furnace flue gas and chemical waste gas, often containing acids, alkalies, oxidizers, organic solvents and other chemical components. Where to choose the filter bag should be based on the chemical composition of the flue gas contained in a reasonable selection of acid-resistant alkali-resistant antioxidant dust filter bag.

2. According to the special nature of dust selection of dust filter bags.

2.1 Dust wettability and adhesion: for hygroscopic and strongly adhesive dust, it is recommended to select a dust filter bag with waterproof laminated filter media.

2.2 The combustibility and charge of the dust: If the dust is flammable, it is recommended to choose a dust bag with flame retardant properties. Anti-static dust filter bags are specifically designed for dust with electrical charge.

3. According to the dust collector cleaning way to choose dust filter bags.

3.1 Mechanical vibration-class bag filter: It is necessary to choose a dust filter bag with a thin and smooth filter material and a soft texture, which facilitates the transfer of vibration waves.

3.2 Reverse air cleaning bag filter: Select a filter bag with a soft texture, stable structure, and good wear resistance.

3.3 Pulse bag filter: Typically utilizes cylindrical filter bags with a frame. It is important to select thick, wear-resistant bags with strong tensile strength.
