TDSL series activated carbon bag filter element

The TDSL series activated carbon bag filter element is an adsorption type filter element developed specifically for industrial fluid and air purification scenarios. It relies on a bag type composite structure to achieve dual purification effects of physical interception and gas phase and liquid phase adsorption. It can stably remove particulate matter, color and odor, and some organic pollutants from fluids under normal working conditions. It is compatible with various standard bag filter housings and provides core consumables for multi industry purification systems that balance filtration and adsorption functions.

The TDSL series activated carbon bag filter element adopts a bag structure composed of an outer primary filtration layer and an inner activated carbon adsorption layer. The outer layer is made of high-strength needle punched non-woven fabric as a pre filtration layer to intercept large particle impurities, and the inner layer is filled with high porosity particle activated carbon or activated carbon fibers. The outer frame can be made of aluminum alloy, galvanized steel plate or waterproof cardboard material, and the edge of the filter bag is sealed by hot fusion technology without leakage. The effective filtration area is much larger than that of the same specification flat filter element, and the activated carbon filling amount is sufficient and evenly distributed. When the fluid passes through, the contact path with the activated carbon is full. The initial resistance is ≤ 85Pa, and it can operate stably under rated conditions without problems such as activated carbon powder leakage or filter bag deformation. It supports adjusting the accuracy of the filter material and the amount of activated carbon filling according to the working conditions.

The TDSL series activated carbon bag filter element is suitable for various purification scenarios, including odor treatment in air conditioning and ventilation systems, pre-treatment of organic waste gas in spraying workshops, decolorization and deodorization of food processing fluids, liquid purification in chemical industries, air purification in electronic manufacturing workshops, and residual chlorine removal in industrial circulating water. It is also suitable for waste gas adsorption in sewage treatment stations, primary purification of VOCs in printing workshops, and odor removal in fresh air systems, achieving dual effects of particle interception and pollutant adsorption.

The core advantages of the TDSL series activated carbon bag filter element are significant. Firstly, the dual purification efficiency is high, and the bag structure greatly increases the fluid contact area, synchronously achieving particle interception and adsorption of odors and organic pollutants. A single filter element can achieve two-stage purification effects; Secondly, the running resistance is low, and the fluffy composite filter bag structure has low wind and water resistance, which will not add too much energy consumption to the system; Thirdly, it is easy to replace and maintain. The standard bag type interface can be directly inserted into the corresponding filter housing, without the need for complex installation tools. A single person can quickly replace consumables; Fourthly, it has strong adaptability, supporting multiple frame materials and non-standard size customization, and can be directly compatible with the vast majority of bag filters of the same specifications on the market, without the need to modify existing equipment.

The common problems encountered in the practical use of TDSL series activated carbon bag filter elements can be addressed accordingly. Firstly, there is powder leakage of activated carbon after operation, which is often caused by damage to the stitching or hot melt sealing parts of the filter bag. It is necessary to check the integrity of the filter bag and replace it with a qualified filter element with a good seal. At the same time, a simple interception layer should be added at the front end to prevent large particles from impacting the filter bag; Secondly, the adsorption effect deteriorates rapidly, often due to the concentration of pollutants far exceeding the design threshold. Depending on the actual type and concentration of pollutants, high filling activated carbon models can be replaced or the replacement cycle can be shortened; The third issue is that the running resistance rises too quickly, often due to the lack of a pre filtration device at the front end. Large particles and impurities quickly block the outer pores of the filter bag. Therefore, a primary filter element can be installed at the front end of the filter element to extend its overall service life.
