Anti-condensation dust collector bags are usually used when the temperature of the dust collector box is lower than the dew point temperature and the humidity of the dust-containing gas is high. Under normal circumstances, if the acidity of dust-containing gas is very small, its dew point temperature is ℃. If the acidity is large, the dew point temperature may be as high as ℃. The production process of water-repellent and oil-proof needle-punched felt is as follows: Fiber opening, carding, laying, pre-thorning, main punching, felting, singeing, calendering, impregnation (waterproof agent), drying, shaping and rolling. Dust collector filter bags whose filter cloth has been treated by waterproofing and oil-proofing are used in situations with high moisture content. Compared with ordinary filter bags, the filter material is less likely to block the paste bag, so the service life of the bag is extended and the cleaning cycle can be extended. The passing gas flow rate is also increased, so it can save a lot of energy consumption and maintenance costs. Anti-condensation, that is, water-repellent and oil-proof. The water-repellent and oil-proof needle-punched dust collector bag is a needle-punched nylon padded with a hydrophobic agent and an oleophobic agent. , formed by pre-baking and baking treatment. After the hydrophobic agent and oleophobic agent are quickly dried, they are attached to the surface of the filter fiber in a mesh shape, thereby reducing the surface tension between water, oil and the filter bag, so that the wet filter media formed by water, oil and dust will not It will adhere to the surface of the dust bag, thus avoiding the bag sticking phenomenon

Each dust removal system uses dust collector bags of different materials according to different working conditions and different dust properties. They are mainly divided into two types: normal temperature and high temperature. The most commonly used ones are normal temperature polyester needle felt. The performance characteristics are filtration wind speed It is higher, has better dust removal effect, and is easy to disassemble and install. Except for shaft kilns with high temperatures, it is better to use high-temperature resistant glass fiber. It is characterized by high temperature resistance, alkali resistance, large air permeability, and the filtration of a single dust collector bag. The area is also larger. According to the actual working conditions, the above two types can be treated with water-proof, oil-proof and anti-condensation treatments to completely solve the bag sticking problem caused by high humidity. They are easy to clean and can also be treated with anti-static treatment to prevent Explosion due to static electricity.
