HTZL series activated carbon folding filter element

The HTZL series activated carbon folding filter element is an industrial grade filter element designed specifically for the synergistic purification of odors, volatile organic compounds, and small and micro particles. With an activated carbon adsorption layer and high-precision folding filter material as the core structure, it can intercept fine particles while removing odor molecules and gaseous pollutants from the medium through the physical adsorption of activated carbon micropores. As the core functional section of a multi-stage purification system, it provides dual protection of particle interception and odor purification for ventilation, fluid treatment, and other scenarios, and is suitable for most industrial and commercial conditions that have dual requirements for medium purity and sensory experience.

The HTZL series activated carbon folding filter element uses high-density activated carbon fibers or granular carbon as the core adsorption layer, and is matched with a gradually denser polyester folding filter material on the outer layer. Through the folding structure, the effective filtration area is greatly expanded, and the impurity holding capacity and adsorption contact time are increased under the same volume. An open metal or plastic support skeleton is installed inside to avoid deformation of the filter material under high pressure conditions. The end cap adopts hot melt or polyurethane sealing technology to achieve no side leakage sealing. The overall can withstand normal operating temperatures below 100 ℃, adapt to normal working pressure differentials of 0.1-0.5MPa, and can be divided into multiple specifications according to the filling amount and filtration accuracy of activated carbon. It supports various universal installation forms such as flat pressure and insertion, and can directly adapt to most standard filters of the same size. Shell.

The HTZL series activated carbon folding filter element is widely used for odor purification in central air conditioning ventilation systems, front-end odor pretreatment in industrial waste gas treatment, primary adsorption of organic waste gas in paint spraying workshops, and can also be used for odor and oil removal in compressed air systems, odor control in clean workshop return air systems, and removal of color and odor in water treatment processes. It is also suitable for the adsorption of trace volatile organic compounds in exhaust gases in the chemical industry and the filtration of gaseous pollutants in commercial fresh air systems, providing dual treatment effects of particle interception and odor purification for different working conditions.

The folding structure of the HTZL series activated carbon folding filter element significantly increases the filtration area. Compared to conventional flat activated carbon filters, the dust holding capacity and adsorption contact efficiency are significantly improved under the same external dimensions, extending the overall service life; The particle interception and activated carbon adsorption functions are integrated into the same filter element, which can simultaneously meet two purification requirements without the need for additional multi-stage filtration units, simplifying the system structure; The overall wind resistance and flow resistance are controlled within a reasonable range, which will not cause significant burden on the air volume and flow rate of the original equipment; The universal installation specifications have strong adaptability, and can directly replace ordinary folding filters of the same size without changing the original equipment structure to complete functional upgrades.

The HTZL series activated carbon folding filter element quickly shows a decrease in odor removal efficiency after use, mostly due to the concentration of pollutants exceeding the design load in the working conditions, and the activated carbon reaching adsorption saturation in advance. The replacement cycle can be shortened according to the actual pollutant concentration, or a primary filter element can be installed at the front end to intercept large particle impurities and avoid rapid blockage of activated carbon pores; After operation, the pressure difference quickly exceeds the rated range. Check if there is a large amount of dust directly entering the filter element at the front end. If the pressure difference still does not fall back after cleaning the impurities accumulated on the inlet side, it indicates that the pores of the filter material are completely blocked. Replace the filter element in a timely manner; After installation, if there is a leakage of the medium side, check whether the sealing element at the end cover is misaligned or aged and deformed. Adjust the sealing position or replace the compatible sealing gasket to solve the problem; After long-term disuse, there may be a situation where the airflow carries carbon powder when reused. This is often due to the loosening and detachment of the surface activated carbon during transportation or storage. After turning on the machine, blow it at a low flow rate for a few minutes, and after the surface floating carbon is cleaned up, it can be put into normal operation.
