Principle and classification of activated carbon filter element

The activated carbon filter element is made of activated carbon particles and binder The inner layer of the filter element is polypropylene skeleton, which is used to strengthen the pressure strength of the filter element The framework is covered with two layers of polypropylene Microfiber felt, which can intercept the liquid passing through the carbon core and bring out particles larger than 10 microns The outer layer of the carbon core is covered with two layers of polypropylene Microfiber felt, which can intercept particles larger than 10-20 microns in the liquid and make the filter element have the dual functions of filtration and purification The outer layer is white plastic net cover, so that the filter element has a complete appearance and clean appearance The two ends of the filter element are equipped with soft rubber end caps, so that the filter element has good sealing performance after being installed into the filter cartridge The finished activated carbon filter element is tightly sealed with plastic film to prevent the filter element from being polluted and keep the filter element in a fresh state Activated carbon filtration: according to the adsorption characteristics of activated carbon, activated carbon is mainly used to remove pollutants in water, decolorize, filter and purify liquid and gas, as well as purification of air, waste gas recovery (such as the recovery of gas benzene in the chemical industry), recovery and extraction of precious metals (such as the absorption of gold) Activated carbon is mainly made of materials with high carbon content, such as wood, coal, shell, bone, petroleum residue, etc In the same condition, the active quality and other characteristics of coconut shell are good because of its large specific surface Activated carbon is a kind of multi pore carbonized substance, which has very rich pore structure and good adsorption characteristics Its adsorption is formed by physical and chemical adsorption force, and its appearance is black In addition to the main carbon, its composition also contains a small amount of hydrogen, nitrogen and oxygen, and its structure looks like a hexagon Due to the irregular hexagon structure, its polyhedral and high surface area characteristics are determined Each gram of active carbon has a specific surface equivalent to 1000 square meters There are two types of activated carbon filter products: compression type and bulk type 1 The compressed activated carbon filter element uses high adsorption value coal activated carbon and coconut shell activated carbon as filter material, and uses food grade adhesive to sinter and compress A layer of non-woven fabric with filtering function is wrapped inside and outside the compressed active carbon filter element to ensure that the carbon powder will not fall off the carbon core itself The two ends of the carbon core are equipped with soft Buna rubber gasket, so that the carbon core can be installed into the filter cartridge with good sealing performance 2 The bulk type activated carbon filter element will put the required activated carbon particles into the special plastic shell, and use the welding equipment to weld the end cover on the two ends of the shell, and put the two ends of the shell into the non-woven filter plates that play the role of filtering, so as to ensure that the carbon core will not drop carbon powder and black water when it is used According to the needs of customers, the shell end cover can be made into different types of connection ports The interface modes are: flat pressure type, pipeline type (models: 4042, 4044, 4046, etc.).
