Problems solved by technology

In the activated carbon filter element with this structure, the activated carbon part is compacted and cannot form a three-dimensional space structure, resulting in low flow rate, large pressure loss, and even clogging when using filtration; In the solid activated carbon filter element, the number of flow channels that can be generated during filtration is very small, so that some activated carbon particles cannot achieve an effective filtering effect. If the filtration pressure is forcibly increased to increase the filtration flow rate, some activated carbon particles will be filtered. The possibility of dispersing, adding activated carbon particle impurities in the filtrate, affecting the filtration effect
Furthermore, in the prior art, this type of filter element is mainly prepared by dry heating and extrusion. In this way, a large amount of dust is emitted during the preparation process, causing serious pollution in the workshop, affecting the environment and requiring more operators. The operation and the presence of dust also have a great impact on the health of the operating workers

Embodiment 1

[0050] An activated carbon filter element, comprising a central rod and a filter layer arranged outside the central rod, the filter layer includes a support fiber web formed by fibrillated cellulose fibers, a bonded fiber web formed by urea fibers, and carbon fibers The adsorption fiber web formed by the raw material and the activated carbon particles distributed in the middle of the above fiber web. It should be noted that carbon fiber can not only play the role of absorbing the fiber net in the product, but also can play the supporting role of supporting the fiber net, but in this application, for the convenience of description, the carbon fiber is classified as the adsorption fiber. The outside of the center rod is wrapped with PP non-woven fabric, and the outside of the filter layer is wrapped with PE and PET composite non-woven fabric. In order to prevent the filter element from falling off from the filter layer and entering the filtrate to affect the filtration effect un...

Abstract

The invention relates to an activated carbon filter element and a preparation method thereof. The activated carbon filter element comprises a cylindrical central rod and a filter layer arranged outside the central rod; the filtering layer comprises supporting fibers, bonding fibers and activated carbon particles, the supporting fibers cover the activated carbon particles to form a net-shaped structure, the bonding fibers are partially wound on the supporting fibers, partially wound on the activated carbon particles and partially simultaneously wound on the supporting fibers and the activated carbon particles, and the supporting fibers are subjected to fibrillation treatment. The invention aims at providing the activated carbon filter element which is higher in filtering flow rate and firmer in structure and the preparation method of the activated carbon filter element which is high in automation degree, free of pollution and capable of adjusting the size of the activated carbon filterelement at any time.

Description

technical field [0001] The invention relates to a filter element and a preparation method thereof, in particular to an activated carbon filter element and a preparation method thereof. Background technique [0002] Activated carbon filter element is a relatively common filter element product, which is mainly used to remove pollutants in water, decolorize, filter and purify liquids and gases, and is also used for air purification and waste gas recovery (such as the removal of gas benzene in the chemical industry) recovery), recovery and refining of precious metals (such as the absorption of gold). [0003] The common activated carbon filter element has a relatively simple structure. The outside is a cylindrical shell, and the inside of the shell is filled with activated carbon material for filtering, and then the filter element is packaged. In the activated carbon filter element with this structure, the activated carbon part is compacted and cannot form a three-dimensional s...
