[0002] Natural gas, as an important energy source, is increasingly widely used. However, during the extraction, transportation, and use of natural gas, various impurities, such as solid particles, often become mixed in. These impurities not only reduce the calorific value and efficiency of natural gas but can also cause severe wear and corrosion to natural gas processing equipment and pipelines, affecting the stability and safety of the system. Currently, various natural gas filters are available on the market, primarily removing impurities from natural gas through physical filtration and chemical adsorption. However, these filters still have some problems in practical applications. For example, the maintenance cost of these filters is high, requiring the replacement of the entire filter element, thus resulting in high operating costs. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figures 1-4 The natural gas filter shown includes a filter element 2, which includes a top shell 24 and a bottom shell 26 arranged symmetrically on the top and bottom sides, and a detachable filter section is provided between the top shell 24 and the bottom shell 26.

[0023] The bottom of the filter section is screwed to the top of the bottom shell 26, and the top of the filter section is screwed to the bottom of the top shell 24. A filter channel for filtering natural gas is formed between the outer peripheral surface of the filter section and the interior of the filter section. A through-type gas outlet 25 is provided on the top shell 24, and the gas outlet 25 is connected to the filter channel.

[0024] With the above technical solution, when personnel need to filter natural gas, the filter part is placed between the bottom shell 26 and the top shell 24, and the bottom shell 26 and the top shell 24 are screwed together with the filter part, thereby fixing the filter part between the bottom shell 26 and the top shell 24. Then, the filter part, the bottom shell 26 and the top shell 24 are installed in the required position. When natural gas is input through the filter part, the filter part filters the natural gas, thereby removing impurities from the natural gas. The filtered natural gas is discharged through the gas outlet 25 on the top shell 24, completing the natural gas filtration. When the filter part needs to be replaced, the top shell 24 and the bottom shell 26 are reversed to separate the top shell 24 and the bottom shell 26 from the filter part, so that the filter part can be disassembled for cleaning.

[0025] When impurities accumulate on the outside of the filter section, in order to clean them, such as... Figure 4 As shown, a motor 27 is fixedly connected to the bottom of the bottom shell 26, a connecting rod 28 is connected to the output end of the motor 27, and a scraper 29 for scraping the circumference of the filter part is fixedly connected to the free end of the connecting rod 28.

[0026] In this embodiment, the motor 27 operates, driving the connecting rod 28 to rotate relative to the bottom shell 26, thereby causing the connecting rod 28 to drive the scraper 29 to rotate relative to the filter section, thus cleaning the impurities remaining on the surface of the filter section and preventing impurities from remaining on the surface of the filter section for a long time.

[0027] Specifically, in one embodiment, regarding the above-mentioned filtering section, such as Figure 1 , Figure 2 and Figure 4 As shown, the filtration section includes a filter housing 21, which is screwed between the top housing 24 and the bottom housing 26. A removable wire mesh 22 is provided inside the filter housing 21, and a removable activated carbon filter element 23 is provided inside the wire mesh 22.

[0028] In this embodiment, before using the device, the activated carbon filter element 23 is placed inside the wire mesh 22, the wire mesh 22 is placed inside the filter shell 21, the filter shell 21 is placed between the top shell 24 and the bottom shell 26, and the filter shell 21 is rotated so that the filter shell 21 is installed between the top shell 24 and the bottom shell 26. When filtering natural gas, the natural gas passes through the filter shell 21, the wire mesh 22 and the activated carbon filter element 23 in sequence, thereby filtering the natural gas.

[0029] In addition, in this utility model, in order to support the top shell 24 and the bottom shell 26, such as Figures 1-3 As shown, a detachable housing component 1 is screwed onto the top shell 24, and the bottom shell 26 is located inside the housing component 1, with the circumferential surface of the housing component 1 open to form a through hole for natural gas to enter.

[0030] In this embodiment, the housing 1 is screwed to the top shell 24, and the housing 1 supports and protects the top shell 24, the filter shell 21 and the bottom shell 26.

[0031] Specifically, in one embodiment, regarding the aforementioned housing member 1, as... Figures 1-3 As shown, the housing component 1 includes an outer shell 11, and an air guide groove 12 is formed on the circumferential surface of the outer shell 11.

[0032] In this embodiment, the filter shell 21, bottom shell 26 and top shell 24 are supported and protected by the outer shell 11, and natural gas is guided into the interior of the outer shell 11 by the gas guide groove 12 on the outer shell 11, thereby filtering the natural gas.

[0033] In order to collect impurities that fall off the filter housing 21, such as Figure 1 , Figure 2 and Figure 4 As shown, a detachable storage shell 13 is screwed onto the bottom of the outer shell 11, and the top of the storage shell 13 is open to form a storage cavity 14.

[0034] In this embodiment, after the scraper 29 cleans the impurities on the filter shell 21, the impurities are received by the collection cavity 14 on the collection shell 13. When personnel need to clean the impurities, the collection shell 13 is reversed to separate the collection shell 13 from the outer shell 11, and the bottom shell 26 can be removed so that the impurities can be collected and processed in a concentrated manner.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
