Technical Field

[0001] The utility model relates to the technical field related to sulfur-containing gas field processing, in particular to a closed chemical cleaning skid-mounted device for high-sulfur gas fields. Background Art

[0002] When producing and processing gas from a gas field, it is necessary to remove the sulfur element inside the gas through a cleaning skid-mounted device, which can not only protect the air environment, but also avoid corrosion to equipment such as pipelines, thereby achieving the effect of protecting pipelines and other equipment. However, when removing the sulfur element inside the gas, the existing cleaning skid-mounted devices mostly adopt a step-by-step processing method. Obviously, setting up multiple skid-mounted devices will undoubtedly increase the space occupied by the equipment, increase the equipment cost, and cause great inconvenience in the subsequent maintenance process. For this reason, we propose a closed chemical cleaning skid-mounted device for high-sulfur gas fields. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] See also Figure 1-6 The utility model provides a technical solution: a closed chemical cleaning skid-mounted device for a high-sulfur gas field, comprising a skid-mounted frame 1, a cleaning tank 11 is fixedly installed in the skid-mounted frame 1, an air inlet pipe 12 and an exhaust pipe 13 which are interconnected with the inner cavity of the cleaning tank 11 are fixedly installed on the front and rear sides of the periphery of the cleaning tank 11, a filter screen 18 and a liquid guide ring 14 are respectively plugged and rotatably installed on the front and rear sides of the inner cavity of the cleaning tank 11, a liquid guide pipe 16 is rotatably installed on the rear side of the cleaning tank 11, a conduit 17 which is interconnected with the inner cavities of the two is fixedly installed between the periphery of the liquid guide pipe 16 and the liquid guide ring 14, and a plurality of nozzles 15 are fixedly installed on the inner end surface of the liquid guide ring 14 at equal intervals.

[0028] Working principle: When treating gas from a gas field, the gas is introduced into the cleaning tank 11 through the air inlet pipe 12. When the gas passes through the filter 18, solid and liquid impurities such as dust in the gas can be adsorbed. When the gas enters the inner side of the liquid guide ring 14, the alkaline solution in the external storage device can be introduced into the liquid guide ring 14 through the liquid guide pipe 16, and the alkaline solution is sprayed into the cleaning tank 11 through the nozzle 15. When the alkaline solution contacts the sulfide in the gas, the reaction between the two forms solid or liquid sulfides that are not easily vaporized, so that these sulfides are separated from the gas field gas, thereby achieving the effect of cleaning the sulfide in the gas.

[0029] Example 2

[0030] A sealing plate 2 is plugged and installed on the front side of the cleaning tank 11, and a threaded ring 21 that cooperates with the front side thread of the outer periphery of the cleaning tank 11 is rotatably installed on the outer periphery of the sealing plate 2. A limiting plug hole 22 is provided on the front end face of the cleaning tank 11, and a limiting plug rod 23 that is plugged and cooperated with the limiting plug hole 22 is fixedly installed on the rear end face of the sealing plate 2, and the length of the limiting plug rod 23 matches the width of the threaded ring 21. A threaded column 24 is fixedly installed on the inner end face of the sealing plate 2, and a positioning ring 25 that is plugged and cooperated with the threaded column 24 is fixedly installed in the middle part of the filter screen 18. A threaded sleeve 28 that cooperates with the outer periphery thread of the threaded column 24 is rotatably installed on one side of the positioning ring 25. A limiting slide groove 26 is provided on the outer periphery of the threaded column 24, and a limiting slider 27 that slides and cooperates with the limiting slide groove 26 is fixedly installed on the inner wall surface of the positioning ring 25.

[0031] When the filter 18 needs to be installed, the filter 18 and the threaded column 24 are plugged into each other through the sliding cooperation between the limiting slider 27 and the limiting slide groove 26. When the threaded sleeve 28 contacts the threaded column 24, the threaded sleeve 28 is restricted. Through the thread cooperation between the two, the threaded sleeve 28 and the filter 18 can be driven to move, and the filter 18 can be installed on one side of the sealing plate 2.

[0032] Then, the sealing plate 2 is inserted and installed on the front side of the cleaning tank 11 through the plug-in cooperation between the limiting plug rod 23 and the limiting plug hole 22. When the threaded ring 21 contacts the cleaning tank 11, the threaded ring 21 is rotated, and the threaded cooperation between the inner wall of the threaded ring 21 and the outer periphery of the cleaning tank 11 can drive the sealing plate 2 to move backward until the sealing plate 2 and the cleaning tank 11 are fitted together, completing the installation of the sealing plate 2 and the filter screen 18.

[0033] On the contrary, by rotating the threaded ring 21 and the threaded sleeve 28 in the opposite direction respectively, the sealing plate 2 and the filter screen 18 can be disassembled. After the sealing plate 2 is disassembled, the front end of the cleaning tank 11 can be opened to facilitate the staff to enter the cleaning tank 11, so as to collect solid and liquid sulfides and inspect and maintain the inside of the cleaning tank 11.

[0034] Example 3

[0035] A connecting seat 3 is fixedly installed on the rear side of the cleaning tank 11, and a liquid guiding frame 31 is fixedly installed on the upper end surface of the connecting seat 3 through a connecting rod. An external pipe 32 is fixedly installed on the outer end of the liquid guiding frame 31. The rear end of the liquid guiding tube 16 is arranged in the liquid guiding frame 31, and limiting clamping plates 33 that are in contact with the front and rear end surfaces of the inner cavity of the liquid guiding frame 31 are fixedly installed on both sides of the outer periphery of the liquid guiding tube 16, respectively. A liquid guiding hole 34 is opened on the outer periphery of the liquid guiding tube 16, and the liquid guiding hole 34 is arranged between the two limiting clamping plates 33. A driven gear 37 is fixedly installed on the outer periphery of the liquid guiding tube 16, and a motor box 35 is fixedly installed on the upper end surface of the connecting seat 3. A driving gear 36 meshing with the driven gear 37 is fixedly installed on the outer end of the motor box 35 through its output shaft.

[0036] When the alkaline solution is injected into the liquid guide ring 14 through the liquid guide tube 16, the motor inside the motor box 35 can be started, and the liquid guide ring 14 can be driven to rotate in the cleaning tank 11 through the outer output shaft and the meshing effect between the driving gear 36 and the driven gear 37, so that the nozzle 15 can evenly spray the alkaline solution in the cleaning tank 11, thereby improving the reaction effect between the alkaline solution and the sulfide;

[0037] Among them, a liquid guide frame 31 is provided, which can be connected to an external alkaline solution storage device through an external pipe 32, so that when the liquid guide tube 16 rotates, the alkaline solution inside the liquid guide frame 31 can enter the liquid guide tube 16 through the liquid guide hole 34, ensuring smooth movement of the alkaline solution.
