The material of the tubular adsorbing material 130a may be selected according to the filtering requirement, and may be selected from a group consisting of activated carbon, zeolite, carbon molecular sieve, silica gel molecular sieve, aerogel, molecular sieve with metal organic framework, molecular sieve with covalent organic framework, bentonite (bentonite), mordenite (mordenite), sepiolite (sepiolite), boron group element material, nitrogen group element material, metal oxide material, organic-inorganic composite material, and lithium type molecular sieve, so that the tubular adsorbing material 130a may adsorb different impurities or pollutants in the fluid, such as dust, volatile organic compound, acidic substance, alkaline substance, condensate, dopant, water gas, or oil gas, and the tubular adsorbing material 130a may further achieve the effects of inhibiting the growth of microorganisms in the fluid and sterilizing, but the present invention is not limited thereto.

In fig. 2B, seven openings 131B are taken as an example, wherein six openings 131B may be distributed at equal angles with another opening 131B as the center, and it is noted that tubular adsorbing materials with different numbers of openings may be simultaneously filled in the filter cartridge structure 100, and the appropriate number of openings may increase the contact and adsorption surface area, thereby improving the filtration efficiency.

In addition, the filter filling material may further include a plurality of strip-shaped adsorbing materials (not shown), a length of each strip-shaped adsorbing material may be 2mm to 2000mm, and by matching the filter filling materials with different shapes and sizes, the pressure loss generated when the fluid passes through the filter cartridge structure 100 may be adjusted, so as to balance the filtering effect and the energy consumption.

Referring to fig. 3, fig. 3 is a schematic partial cross-sectional view of a filter cartridge structure 200 according to another embodiment of the present invention. The filter cartridge structure 200 is similar to the filter cartridge structure 100, but the filter filling material in the filter cartridge structure 200 includes a plurality of fibrous adsorbent materials 230. Importantly, although the filter cartridge structure 100 of the present invention mainly comprises the tubular adsorbing material 130a, and the filter cartridge structure 200 mainly comprises the fibrous adsorbing material 230, in practical application, the tubular adsorbing material and the fibrous adsorbing material, or the aforementioned strip adsorbing material, can be loaded between the inner cartridge and the outer cartridge according to the filtering requirement, and therefore the present invention is not limited thereto.

Referring to fig. 4, fig. 4 is a perspective view of the fibrous adsorbing material 230 in the filter cartridge structure 200 of fig. 3.

The following adsorption efficiency tests were performed on the filter cartridge structures of the first comparative example, the second comparative example, and the first to fifth embodiments, and the types and structural parameters of the filter fillers filled in the first comparative example, the second comparative example, and the first to fifth embodiments are listed in the following table:

referring to fig. 5, fig. 5 is a graph showing adsorption efficiency tests of the first comparative example, the second comparative example, the first embodiment, and the second embodiment. The experiment was conducted by measuring the concentration of isopropanol in the gas passing through the cartridge structure at different times and calculating the C/C ₀ The values are plotted in FIG. 5, where C is the outlet concentration, C0 is the inlet concentration, C/C ₀ The breaking-out ratio (failure degree) of the test gas in the adsorption efficiency verification process is determined. In the present experiment, the first comparative example, the second comparative example, and the first and second examples were tested at a flow rate of 2.5CMM (cubic meter per minute) with a test gas having 10ppm to 12ppm of isopropyl alcohol, and the test conditions and results thereof are shown in the following table two:

as can be seen from the second table and fig. 5, the breaking time of the first and second embodiments is much longer than that of the first and second comparative examples, and the first and second embodiments have a higher capturing ratio, because the filter cartridge structure of the present invention uses the tubular adsorbing material, a shorter mass transfer path and a larger contact area can be provided, thereby increasing the adsorbing capacity of the filter filling material, and further improving the filtering efficiency of the fluid.

Referring to fig. 6, fig. 6 is a diagram illustrating absorption efficiency test charts of the second to fifth embodiments. In this experiment, the second to fifth examples were also tested at a flow rate of 2.5CMM with a test gas having 10ppm to 12ppm isopropyl alcohol. As can be seen from fig. 6, the filtering filler of the second to fifth embodiments has different structures, so that the gas passing through the filter cartridge has different pressure losses, thereby affecting the contact time between the gas and the filtering filler and producing different filtering effects. The outer diameter and the length of the tubular adsorption material can be adjusted according to the filtration requirement, so that the fluid can generate different pressure changes, and the filter cartridge structure of the utility model is more flexible in use.

To sum up, the utility model discloses a strain a section of thick bamboo structure through using tubulose adsorption material and/or fibrous adsorption material, adsorption material body structure provides relatively short matter and passes route and great area of contact, can make the fluid evenly pass through and strain a section of thick bamboo and filter, so can reach good filter effect under the condition of low pressure loss, reduce the use amount of the energy simultaneously.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
