[0025] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] This utility model embodiment provides a natural gas purification device, such as... Figure 1-7 As shown, the natural gas purification device includes: a filter box 1, wherein a filter screen 2 is provided inside the filter box 1 for filtering impurities in the natural gas; a purification box 3 disposed on one side of the filter box 1 for purifying the natural gas, the purification box 3 being connected to the filter box 1; a water removal box 4 assembled on one side of the purification box 3 for treating moisture in the natural gas, the water removal box 4 being connected to the purification box 3; and a cleaning mechanism assembled on the filter box 1 for cleaning the filter screen 2.

[0027] In this embodiment, the device is equipped with a controller, model OMRON E5CC-QX2ASM-800. The controller allows for the control and operation of the entire device. When purifying natural gas, the natural gas is introduced into the filter box 1, where impurities are filtered out by the filter screen 2. The purified natural gas then sequentially enters the purification box 3 and the dewatering box 4. The purification box 3 further purifies the filtered natural gas, while the dewatering box 4 removes moisture from the natural gas. This process effectively purifies the natural gas. When the filter screen 2 needs cleaning, the controller activates the cleaning mechanism to automatically clean it, avoiding the problem of forgetting to clean manually, ensuring a consistent cleaning frequency for the filter screen 2, and effectively preventing clogging. This improves the purification effect of the natural gas. The entire device can purify natural gas and automatically clean the filter screen 2, avoiding the problem of forgetting to clean manually, ensuring a consistent cleaning frequency for the filter screen 2, and effectively preventing clogging. This, in turn, improves the purification effect of the natural gas.

[0028] In a further preferred embodiment of this utility model, the cleaning mechanism includes: two cleaning pipes 5 rotatably mounted on the filter box 1, the two cleaning pipes 5 being located on both sides of the filter screen plate 2, and the cleaning pipes 5 being provided with a plurality of nozzles 6; a connecting pipe 8 fixedly mounted on one side of the outer wall of the filter box 1, the connecting pipe 8 being connected to two flexible hoses 7, and the two flexible hoses 7 being respectively connected to the two cleaning pipes 5; and an adjustment mechanism disposed between the filter box 1 and the two cleaning pipes 5, the adjustment mechanism being used to adjust the position of the nozzles 6 cleaning the filter screen plate 2.

[0029] In this embodiment, during cleaning, the connecting pipe 8 is connected to the corresponding pressurized pump source pipeline. The cleaning fluid is delivered to the cleaning pipe 5 through the connecting pipe 8 and the hose 7, and then sprayed out by the nozzle 6 to clean the filter screen 2. During cleaning, the cleaning position of the nozzle 6 can be adjusted as needed by activating the adjustment mechanism through the controller, thereby cleaning the filter screen 2 more comprehensively and effectively, avoiding the filter screen 2 from being blocked due to the accumulation of impurities, and improving the effect and efficiency of natural gas impurity removal and purification.

[0030] In a further preferred embodiment of the present invention, the adjustment mechanism includes: two spur gears 10 respectively fixedly sleeved on the two cleaning pipes 5, the two spur gears 10 meshing with each other; a first servo motor 9 fixedly installed on the outer wall of one side of the filter box 1, the output shaft of the first servo motor 9 being connected to one end of one of the cleaning pipes 5.

[0031] In this embodiment, when using the adjustment mechanism, the controller starts the first servo motor 9 to rotate in both directions (from 0 to 90 degrees). Its output shaft drives the connected cleaning pipe 5 to rotate. Since the two spur gears 10 mesh with each other, the other cleaning pipe 5 will also rotate synchronously. In this way, the nozzles 6 on the two cleaning pipes 5 can cover the entire surface of the filter screen 2, achieving all-round cleaning. By setting the adjustment mechanism, not only is the cleaning efficiency improved, but it also ensures that every part of the filter screen 2 is thoroughly cleaned, thereby avoiding the clogging problem caused by incomplete cleaning of certain areas of the filter screen 2, and further improving the impurity removal and purification effect of the natural gas purification device.

[0032] In a further preferred embodiment of this utility model, the purification tank 3 is provided with a spraying mechanism, which is used to spray purification liquid into the purification tank 3 and purify natural gas. The spraying mechanism includes: a water pump 11 fixedly installed on one side of the purification tank 3; and a spray pipe 12 fixedly installed inside the purification tank 3. The spray pipe 12 is connected to the water outlet of the water pump 11, and the spray pipe 12 is provided with multiple spray heads.

[0033] In this embodiment, during the natural gas purification process, the natural gas filtered by the filter box 1 enters the purification box 3 through the air pump. At this time, it is necessary to further purify the impurities or harmful substances in the natural gas. The water inlet of the water pump 11 is connected to the corresponding pipeline. The water pump 11 is started to transport the alkanolamine solution to the spray pipe 12, and then sprayed out by the spray head. The alkanolamine solution reacts chemically with hydrogen sulfide and some organic sulfur in the natural gas to generate soluble compounds, thereby achieving sulfur purification treatment.

[0034] In a further preferred embodiment of this utility model, a dispersing mechanism is provided on the purification tank 3. The dispersing mechanism is used to disperse the purification liquid in the purification tank 3. The dispersing mechanism includes: a second servo motor 13 fixedly installed on one side of the outer wall of the purification tank 3; and a mounting shaft 14 rotatably installed on the purification tank 3. A dispersing frame 15 is fixedly installed on the mounting shaft 14, and the output shaft of the second servo motor 13 is connected to one end of the mounting shaft 14 through a coupling.

[0035] In this embodiment, when using the dispersing mechanism, the controller starts the second servo motor 13 to drive the mounting shaft 14 to rotate, which in turn drives the dispersing frame 15 to rotate inside the purification tank 3. The rotation of the dispersing frame 15 can effectively disperse the purification liquid inside the purification tank 3, making it more fully mixed with the natural gas, increasing the contact area between the purification liquid and the natural gas, improving the purification efficiency, and enabling impurities or harmful substances in the natural gas to be more effectively absorbed or reacted by the purification liquid.

[0036] In a further preferred embodiment of the present invention, a plurality of guide plates 16 are fixedly installed inside the water removal tank 4, and the guide plates 16 are used to guide the natural gas entering the water removal tank 4.

[0037] In this embodiment, after natural gas enters the dewatering tank 4 through the air pump, multiple guide plates 16 can guide and restrict the flow path of the natural gas, causing it to flow in the dewatering tank 4 in a specific direction and path. In this way, the natural gas can come into contact with the dewatering medium triethylene glycol solution more evenly and fully, greatly improving the dewatering efficiency and ensuring that the moisture in the natural gas is effectively removed. This, in turn, improves the overall natural gas purification device's treatment effect on natural gas and ensures the dryness and quality of the output natural gas.

[0038] In a further preferred embodiment of this utility model, a stirring mechanism is provided inside the dewatering tank 4. The stirring mechanism is used to stir the natural gas and dewatering agent inside the dewatering tank 4. The stirring mechanism includes: multiple stirring frames 17 rotatably installed inside the dewatering tank 4; a third servo motor 18 fixedly installed on one side of the outer wall of the dewatering tank 4, the output shaft of the third servo motor 18 being connected to one end of one of the stirring frames 17 via a coupling; and multiple synchronous pulleys 19 respectively fixedly sleeved on the multiple stirring frames 17, with multiple synchronous belts 20 sleeved on the multiple synchronous pulleys 19.

[0039] In this embodiment, during the dehydration of natural gas, the third servo motor 18 is activated to drive one of the stirring racks 17 to rotate. Due to the arrangement of multiple synchronous pulleys 19 and synchronous belts 20, the multiple stirring racks 17 rotate synchronously. The rotation of the stirring racks 17 can fully stir the natural gas and the dehydrating agent triethylene glycol solution in the dehydration tank 4. The triethylene glycol solution has a strong affinity for water vapor and can absorb water vapor in the natural gas, making the two mix more evenly. This accelerates the reaction or adsorption rate of moisture in the natural gas with the dehydrating agent, greatly improving the dehydration efficiency. This not only ensures that the moisture in the natural gas is removed more thoroughly, but also improves the working performance of the entire natural gas purification device and the quality of the output natural gas.

[0040] In summary, compared with related technologies, this device can purify natural gas and automatically clean the filter screen 2, avoiding the problem of forgetting to clean it manually, ensuring the cleaning frequency of the filter screen 2, effectively preventing the filter screen 2 from clogging, and thus improving the purification effect of natural gas.

[0041] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
