Acrylic needle felt dust bag is a key part of the bag filter operation. Usually the cylindrical filter bag is suspended vertically in the dust collector. The fabric and design of the dust filter bag should be as clean as possible, easy to dust and durable. In pulsed and air box type pulse dust collectors, dust adheres to the outer surface of the dust bag. When the dust-laden gas passes through the dust collector, the dust is trapped on the outer surface of the filter bag, and the clean gas passes through the filter material and enters the inside of the filter bag. The cage inside the filter bag is used to support the filter bag to prevent the filter bag from collapsing, while it contributes to the dust cake and redistribution.
1. The continuous working temperature is 130 degrees, and the instantaneous temperature does not exceed 140 degrees;
2, good acid and alkali resistance, PH value between 3-11;
3, the relative humidity is less than 30%, pay attention to oxidation.
Acrylic needle felt dust bag is the key component to determine the dust removal efficiency and working temperature of the bag filter. The cost of changing the filter bag is the main maintenance cost of the bag filter. Therefore, the working life of the filter bag is related to the operation status of the dust collector. Cost, choosing the right filter material and a well-designed structure is especially important. The filter material should be selected according to the temperature, humidity and chemical characteristics of the gas; the size, weight, shape, honing and dust concentration, filtration speed, cleaning method, discharge concentration and bag filter work of the particles. Institutions and other factors are considered together. Under normal circumstances, the pulse jet bag filter adopts needle felt, and the chamber back blow bag filter or mechanical vibrating bag filter is woven.
Acrylic needle felt filter bag chemical name is polyacrylonitrile, which is used as raw material to make felt by needle punching method, and then subjected to special water repellent treatment to obtain acrylic medium temperature anti-hydrolysis needle-punched filter felt. The needle felt is reinforced with acrylic woven fabric as the base fabric to enhance the vertical and horizontal strength. It has excellent chemical resistance and hydrolysis resistance, and is widely used in dust collection of waste incineration, asphalt, spray dryer, coal mill, power plant, etc. It has the following
