Air Dust Removal during Production Process Filter Bag

Air dust removal during production process Filter Bag can be customized.And it is a key part of the operation process of a bag filter, and usually a cylindrical filter bag is vertically suspended in the dust collector. The fabric and design of the filter bag should strive for efficient filtration, easy dust removal, and durability.

In pulse and air box pulse dust collectors, dust is attached to the outer surface of the Air dust removal during production process Filter Bag. When dusty gas passes through the dust collector, the dust is trapped on the outer surface of the filter bag, while clean gas enters the interior of the filter bag through the filter material. The cage frame inside the filter bag is used to support the filter bag, prevent it from collapsing, and at the same time, it helps to remove and redistribute dust cakes.

*The filter cloth relies on the thickness of the entire filter layer for filtration, belonging to deep filtration

*The entire depth direction of the filter layer is formed by fibers to form a three-dimensional porous structure, from loose to dense from inside to outside, forming gradient filtration

*High pollution capacity, long filtration life, and low pressure difference

Material:PP (polypropylene), PE (polyester), PTFE (polytetrafluoroethylene)

Rings:Stainless steel ring, Plastic ring

Product Feature And Application

1.The polypropylene Air dust removal during production process Filter Bag , which has good wear resistance and high elastic recovery rate. When the load increases, the creep elongation of polypropylene is greater than that of polyester. Polypropylene can withstand a temperature of 90 ℃, and its chemical properties are the best among all chemical fibers. It is both acid and alkali resistant. It has good resistance to other acids except for oxidizing acids such as chlorosulfonic acid and concentrated nitric acid. We are a professional manufacturer of polypropylene needle felt, with a variety of product models and scientifically validated materials. It can effectively filter and has high filtration accuracy. In addition, the price of polypropylene needle felt is discounted and the quality is superior.

2.The polyester air dust removal during production process needle punched felt filter bag is made by multiple needle punctures and appropriate hot rolling treatment. After loosening, carding, and laying short fibers into a fiber mesh, the fiber mesh is then reinforced into a cloth through a needle. The needle has hooks and thorns, and the fiber mesh is repeatedly punctured and reinforced with hooks and straps to form a needle punched non-woven fabric. The non-woven fabric has no distinction between warp and weft lines, and the fibers in the fabric are messy, with little difference in radial and weft performance.

3.The material used in the PTFE Air dust removal during production process Filter Bag is PTFE fiber, which is currently the best chemical resistant fiber found. It is extracted from "fluorine" stone, and its fiber melting point is 327 ℃. The instantaneous temperature resistance can reach 300 ℃. PTFE fiber has good low friction, difficult to burn, and good insulation and insulation properties. It should be noted that due to the low friction coefficient of PTFE fibers, the bonding ability of non-woven PTFE felt is relatively poor, resulting in high requirements for cleaning pressure of PTFE needle felt. It is necessary to strengthen control during design and use

Dust cleaning method

1. Gas cleaning: Gas cleaning refers to the use of high-pressure gas or external atmosphere to blow back the filter bag to remove dust accumulation on the filter bag. Gas cleaning includes pulse jet cleaning, reverse blowing cleaning, and reverse suction cleaning.

2. Mechanical vibration cleaning: divided into top vibration cleaning and middle vibration cleaning (both for filter bags), it is achieved by periodically rotating the mechanical vibration device to clean the accumulated dust on each row of filter bags.

3. Manual tapping: It is the process of manually tapping each filter bag to remove any accumulated dust.
