Description

Technical Field

[0001] This utility model relates to the field of sediment treatment technology, specifically to a device for treating iron sulfide sediments. Background Technology

[0002] Iron sulfide precipitates are iron-containing sulfide precipitates formed by the reaction of hydrogen sulfide with iron or iron compounds.

[0003] Iron sulfide deposits are easily generated in oil, natural gas, or other industrial processes. These deposits can react with water and oxygen in humid environments to produce corrosive substances such as sulfuric acid, leading to corrosion of the inner wall of pipelines. Furthermore, the accumulation of iron sulfide deposits in pipelines can block them, affecting the flow of oil and reducing transportation efficiency. Therefore, it is necessary to treat the iron sulfide deposits in oil pipelines.

[0004] Therefore, we have made improvements to this and proposed a device for treating iron sulfide deposits. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a device for treating iron sulfide deposits, comprising a housing placed on one side of an oil pipeline. Two placement cavities are formed on the top surface of the housing. One placement cavity contains a rotating shaft with multiple stirring rods evenly arranged on it, and a motor is fixedly mounted on the shaft. The other placement cavity is used to hold a pipeline cleaning device. An air inlet pipe and a water injection pipe are connected to the top of the oil pipeline. Two pipeline cleaning devices are present, both slidably disposed within the oil pipeline. A liquid pump is installed on one side of the housing, and the outlet of the liquid pump is connected to a connecting pipe that communicates with the water injection pipe.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Example: Figures 1 to 4 As shown, this utility model discloses an iron sulfide deposit treatment device, including a housing 1. The housing 1 is placed on one side of an oil pipeline 4. Universal wheels are respectively installed at the four corners of the bottom of the housing 1, and a handle is fixedly installed on one side of the housing 1. During cleaning, the housing 1 can be pushed to the side of the oil pipeline 4 that needs to be cleaned.

[0023] The top surface of the housing 1 has two placement cavities 12. A rotating shaft 9 is rotatably installed in one of the placement cavities 12. Multiple stirring rods 10 are evenly arranged on the rotating shaft 9, and a motor 2 is fixedly installed on the rotating shaft 9. The top end of the rotating shaft 9 is fixedly connected to the output end of the motor 2. The solvent can be poured into the placement cavity 12, and the rotating shaft 9 is driven to rotate by the motor 2. The rotating shaft 9 drives the stirring rods 10 to rotate, stirring the solvent and preventing clumping. The solvent is an existing substance used to dissolve iron sulfide precipitates, which will not be described in detail here.

[0024] Another placement chamber 12 is used to place the pipeline pig 7; the top of the oil pipeline 4 is connected to an air inlet pipe 5 and a water injection pipe 6. There are two pipeline pigs 7, and both pipeline pigs 7 are slidably installed inside the oil pipeline 4; the air inlet pipe 5 can be connected to an existing external air pump, and the water injection pipe 6 can also be connected to an existing external water supply equipment. During cleaning, the solvent Ronggong water injection pipe 6 is first injected into the oil pipeline 4 to dissolve the iron sulfide precipitate inside the oil pipeline 4. Then, water is injected into the oil pipeline 4 through the water injection pipe 6 to first wash away the dissolved iron sulfide precipitate. Then, the two pipeline pigs 7 are placed inside the oil pipeline 4 in sequence, keeping a certain distance between the two pipeline pigs 7. Water is injected into the oil pipeline 4 again through the water injection pipe 6 so that the water is between the two pipeline pigs 7. Then, the pipeline pigs 7 are moved by air pressure to scrape the inner wall of the oil pipeline 4.

[0025] A liquid pump 3 is installed on one side of the housing 1. The outlet of the liquid pump 3 is connected to a connecting pipe 8 that is connected to the water injection pipe 6. The connecting pipe 8 can be connected to the water injection pipe 6, and the solvent can be introduced into the oil pipeline 4 under the action of the liquid pump 3.

[0026] The top of the housing 1 is provided with two cover plates for covering the placement cavity 12. One cover plate is fixedly set on the top of the housing 1, the motor 2 is mounted on the cover plate, and the cover plate is provided with a feed port; the other cover plate is slidably set on the top of the housing 1, and the cover plate serves to cover the cavity.

[0027] The liquid pump 3 is fixedly installed on one side of the placement cavity 12 where the rotating shaft 9 is installed. A partition 11 is fixedly installed in another placement cavity 12, and two arc-shaped surfaces are opened on one side of the inner wall of the placement cavity 12. The arc-shaped surfaces match the pig 7, which helps to enhance the stability of the pig 7 in the placement cavity 12.

[0028] The oil pipeline 4 is detachably fitted with a pipeline sealing cover 41 at one end near the housing 1, and the air inlet pipe 5 is located on the side near the pipeline sealing cover 41. The pipeline sealing cover 41 can be opened by existing technology to facilitate the insertion of the pipeline pig 7 into the oil pipeline 4. When cleaning the oil pipeline 4 with the pipeline pig 7, the pipeline sealing cover 41 needs to be closed to ensure sealing.

[0029] The two ends of the pipeline pig 7 are respectively fitted with rubber sleeves 71. The two ends of the pipeline pig 7 are recessed towards the middle, and the two ends of the pipeline pig 7 are slidably connected to the inner wall of the oil pipeline 4. The pipeline pig 7 moves under the push of air pressure, which makes it easier to clean the impurities on the inner wall of the oil pipeline 4.

[0030] There is a distance between the two pigs 7. The pig 7 that is far away from the pipe sealing cap 41 is set at the end of the water injection pipe 6 that is far away from the air inlet pipe 5, and the pig 7 that is close to the pipe sealing cap 41 is set at the end of the air inlet pipe 5 that is close to the water injection pipe 6. After the first pig 7 is put into the oil pipeline 4, it is pushed to the end of the water injection pipe 6 by air pressure. Then the second pig 7 is put into the oil pipeline 4.

[0031] During operation, the solvent in the tank 1 is injected into the oil pipeline 4 by the liquid pump 3. The solvent dissolves the iron sulfide precipitate. After dissolution, water is used to clean the inside of the oil pipeline 4. Under the action of the pipeline pig 7, the residue on the inner wall of the oil pipeline 4 is scraped off to prevent excessive iron sulfide precipitate in the oil pipeline 4 from affecting the oil transportation and the service life of the oil pipeline 4.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
