Description

Technical Field

[0001] The utility model belongs to the field of cleaning methods using liquid or steam, and in particular relates to a pipe cleaning device. Background Art

[0002] After the high-temperature and high-pressure natural gas in the underground rock formation is extracted to the ground, the pressure and temperature decrease, and many impurities dissolved in the natural gas (polysulfides, silt, water) will precipitate and deposit in the natural gas gathering and transportation pipelines. Due to the high content of hydrogen sulfide in high-sulfur gas fields, there will be a large amount of sulfur-containing pollutants such as sulfur-containing sludge and elemental sulfur in the natural gas gathering and transportation pipelines. The pipe cleaner is a special tool for removing impurities from the pipeline. After the pipe cleaning operation of the gathering and transportation pipeline of the high-sulfur gas field, a large amount of sulfur-containing pollutants will adhere to the surface of the pipe cleaner. The operator needs to clean the pipe cleaner to meet the requirements for reuse. When the pipe cleaner is cleaned by manual cleaning, the workload of the personnel is relatively large, time-consuming and labor-intensive, and the pipe cleaner is not easy to clean, and the cleaning effect is poor.

[0003] The Chinese utility model patent with the authorization announcement date of April 6, 2005 and the authorization announcement number CN2690061Y discloses a pipe cleaner cleaning device, which mainly includes a cleaning bucket (i.e., cleaning box), which is connected to a heating water tank through a pipeline. The inner cavity of the cleaning bucket forms a cleaning chamber, and spray pipes are installed on the upper part and the side of the cleaning chamber, and a rotating chassis driven by a motor (i.e., a rotating drive device) is installed at the bottom. When working, the pipe cleaner to be cleaned is moved to the top of the cleaning device by a crane, and the pipe cleaner is placed after the upper cover of the cleaning bucket is opened. The pipe cleaner is driven to rotate by a low-speed rotating mechanism, and the spray pipe sprays 80°C high-pressure hot water to the pipe cleaner for cleaning. The cleaned mixture flows into the heating water tank for treatment.

[0004] The existing pipe cleaning device directly uses hot water to flush the sewage attached to the pipe cleaning device. The problem is that the hot water will release hydrogen sulfide gas after flushing and breaking up the sulfur-containing dirt, which will endanger the personal safety of the operators and cause environmental pollution. In addition, the waste liquid after flushing also contains dangerous and toxic substances such as hydrogen sulfide and sulfur, which will also bring hidden dangers to the safety of surrounding personnel and the environment.

DETAILED DESCRIPTION

[0023] The utility model aims at the characteristics of sulfur-containing sludge deposited in the gathering and transportation pipeline of a high-sulfur gas field, and proposes an adaptive pig cleaning device. The pig with sulfur-containing sludge attached to the surface first undergoes a neutralization reaction in a neutralization reaction chamber to convert harmful substances such as hydrogen sulfide in the sulfur-containing sludge into non-toxic substances, and then the pig after the neutralization reaction is transported to the cleaning chamber for flushing, thereby avoiding the problems of hydrogen sulfide being released in the traditional cleaning process and the flushing wastewater containing hydrogen sulfide affecting the safety of operators and the surrounding environment, thereby improving the safety of such pig cleaning operations.

[0024] Furthermore, the nozzle of the pipe cleaner cleaning device is connected to a flushing liquid / drying gas conversion joint. After the pipe cleaner is flushed clean, the pipe cleaner is dried using drying gas such as high-pressure hot air, which can avoid secondary pollution caused by the water-carrying pipe cleaner during transportation.

[0025] By further optimizing the nozzle and the rotary drive device, the structure can be further simplified and the efficiency and adaptability of the cleaning operation of the pipe cleaner can be improved.

[0026] The implementation process of the utility model is described in detail below in conjunction with specific embodiments.

[0027] Example 1

[0028] The pipe cleaning device of this embodiment is as follows: Figure 1 to Figure 4 As shown, it includes a cleaning box 1, which is composed of a box body 2 and a box cover 3 that seals the box body. The pipe cleaner 4 to be cleaned completes the cleaning operation in the cleaning box 1, thereby ensuring the airtightness and independence, and minimizing the interference of the cleaning operation on the surrounding personnel and environment.

[0029] like Figure 1 As shown, the box body 2 is a rectangular parallelepiped structure, and a box body partition 5 is provided in the middle of the length direction of the box body 2, and the box body partition 5 divides the inner cavity of the box body 2 into a cleaning chamber 6 located on the left and a neutralization reaction chamber 7 located on the right. The neutralization reaction chamber 7 is used to contain the neutralization cleaning liquid. The pig 4 to be cleaned is placed in the neutralization reaction chamber 7 containing the neutralization cleaning liquid, and the acidic substances such as hydrogen sulfide contained in the sulfur-containing sludge can be reacted with the neutralization cleaning liquid by using the acid-base neutralization reaction principle to convert them into non-toxic and harmless substances, thereby playing the role of neutralization and preliminary cleaning.

[0030] A rotation drive device for driving the pipe cleaner 4 to rotate is provided in the cleaning chamber 6. The rotation drive device can drive the pipe cleaner 4 to rotate around its axis. There is no requirement for the specific driving method, and a conventional motor drive or manual drive method can be used. There is no specific restriction on the axis direction of the pipe cleaner 4, and it can be vertical, horizontal, or other directions suitable for the arrangement of the nozzle and flushing the dirt attached to the pipe cleaner 4. In this embodiment, if Figure 1 As shown, the pipe cleaner 4 is placed transversely in the cleaning chamber 6, and the axis of the pipe cleaner 4 extends in the left-right direction.

[0031] A pipe cleaner support 8 is provided in the cleaning chamber 6. The pipe cleaner support 8 can support the weight of the pipe cleaner 4 and guide the pipe cleaner 4 to rotate around its axis under the rotation driving force without sliding forward and backward. The rotation driving device of the pipe cleaner 4 includes a connecting piece rotatably mounted on the side wall of the box body, one end of the connecting piece is connected to the pipe cleaner 4, and the other end is connected to the crank 9 outside the box body. In this way, by shaking the crank 9 outside the box body, the connecting piece and the pipe cleaner 4 can be driven to rotate on the pipe cleaner support 8. Figure 1 As shown, the connecting member includes a connecting rod 10 and a circular hook 11 arranged at the end of the connecting rod, and the circular hook 11 can be firmly connected with the hook of the lifting ring on the pipe cleaner, and the connecting rod 10 is assembled on the side wall of the box through a sealed bearing, thereby ensuring the sealing of the connecting rod 10 assembled on the side wall of the box.

[0032] In order to prevent the pipe cleaner 4 from falling directly onto the bottom plate of the box due to misoperation, thereby causing damage to the bottom plate of the box and the pipe cleaner 4. Figure 2 , Figure 3 As shown, a protection rod group is also provided below the pipe cleaner support 8, and the protection rod group is a group of protection rods 12 arranged in parallel and spaced between the box partition 5 and the corresponding box side wall, and the protection rods 12 extend along the length direction of the box 2 and are arranged in a concave arc shape on the box side wall. In this way, when the pipe cleaner 4 falls downward, the protection rod group can play a certain buffering role to prevent the pipe cleaner 4 from directly colliding with the box bottom plate.

[0033] Drain valves 13 are provided on the box body 2 corresponding to the cleaning chamber 6 and the neutralization reaction chamber 7, so that after the cleaning chamber 6 and the neutralization reaction chamber 7 complete the corresponding cleaning and neutralization reaction operations, the waste water can be discharged in time through the drain valves 13.

[0034] One end of the box cover 3 is hinged on the box body 2, and the box cover 3 can be turned over on the box body 2 to achieve a sealed fit between the box body 2 and the box cover 3. Figure 2 As shown, the cross section of the box cover 3 is semicircular, and a semicircular box cover partition 14 is provided inside the box cover 3. The box cover partition 14 is arranged corresponding to the box body partition 5. After the box cover 3 is closed with the box body 2, the box cover partition 14 and the box body partition 5 are butted together. In this way, the box cover space above the neutralization reaction chamber 7 and the cleaning chamber 6 can be further separated in the box body 2 to form two relatively independent processing spaces (i.e., the cleaning space and the neutralization reaction space), ensuring that the neutralization reaction process and the flushing process will not affect each other.

[0035] There is a spray pipe in the cleaning box, and the nozzle of the spray pipe can spray cleaning liquid to the two ends and sides of the pipe cleaner, so as to effectively wash all parts of the pipe cleaner. Figure 1 As shown, the spray pipe includes an arc-shaped connecting pipe 15 arranged on the inner side of the box cover corresponding to the cleaning chamber 6, one side of the arc-shaped connecting pipe 15 is connected to the flushing liquid / drying gas conversion joint 16 on the outer side of the box cover through a short pipe, and the other side is connected to a group of straight pipes 17, the straight pipes 17 extend along the length direction of the box body 2 and are arranged at intervals in the length direction of the arc-shaped connecting pipe 15, and the spray heads 18 are arranged at intervals on the straight pipes 17. Under this design, the distribution area of ​​the spray heads 18 is larger, and the flushing of the pipe cleaner 4 is more effective. In addition, high-pressure spray heads 18 in different directions can be distributed on the straight pipe 17, so as to realize multi-directional flushing of the pipe cleaner 4. In other implementation situations, the above-mentioned arc-shaped connecting pipes 15 can be respectively arranged at both ends of the straight pipe 17, and the spray heads 18 are also arranged on the arc-shaped connecting pipe 15, so that the spray heads 18 cover the two ends and the side of the pipe cleaner 4 in a larger range, so as to realize effective flushing of various parts of the pipe cleaner 4.

[0036] The flushing liquid / drying gas conversion joint 16 adopts a quick-release joint form, which can be easily connected to the flushing source and the drying gas source. When the flushing is completed, the flushing pig 4 can be further dried by spraying hot air or other drying gas to the pig 4 to avoid secondary contamination.

[0037] A valve-controlled exhaust pipe 19 is also provided on the box cover corresponding to the cleaning chamber 6, and the exhaust pipe 19 is used to discharge the drying gas for drying the pipe cleaner 4. The exhaust pipe 19 is welded on the box cover 3, so that the cleaning chamber 6 can be sealed and the exhaust can be freely controlled.

[0038] The pig cleaning device also includes a transfer device, which realizes the transfer of the pig 4 from the neutralization reaction chamber 7 to the cleaning chamber 6, which saves manpower on the one hand and prevents the operator from directly contacting the pig 4 on the other hand. Figure 1 , Figure 3 As shown, the cleaning box 4 and the transfer device are both installed on a mobile carrier, which facilitates the movement of the device and allows the cleaning of the pipe cleaner 4 to be carried out conveniently at the site where the pipe cleaner 4 is used.

[0039] In this embodiment, the mobile carrier is a flatbed trolley 20, which includes a bottom support plate 21 and a push handle 22 connected to the bottom support plate, and the bottom surface of the box body is welded to the bottom support plate 21. The transfer device includes a vertical pole 23 arranged between the box body 2 and the push handle 22, and the upper end of the vertical pole 23 is connected to a crossbeam 24 perpendicular to the vertical pole 23, and the crossbeam 24 is provided with a slide rail 25 and a slider, and the slider is connected to a fall chain 26, and the hook 27 of the fall chain 26 can hook the lifting ring of the pipe cleaner 4. Through the lifting and translational actions of the hook, the lifting and translation of the pipe cleaner 4 can be realized, and then the pipe cleaner can be transferred from the neutralization reaction chamber 7 to the cleaning chamber 6.

[0040] Example 2

[0041] The pipe cleaning device of this embodiment includes a cleaning box fixedly installed on a mobile carrier. The cleaning box has a box body and a box cover. A box body partition is provided in the box body to divide the inner cavity of the box body into a cleaning chamber and a neutralization reaction chamber.

[0042] A bracket is provided in the cleaning chamber to support the horizontally placed pipe cleaner, a rotating drive device drives the horizontally placed pipe cleaner on the bracket to rotate around its axis, and a nozzle is provided in the cleaning box to spray the ends and sides of the pipe cleaner. The above rotating drive device and nozzle are arranged in the same manner as in Example 1. This example mainly describes the implementation of the bracket:

[0043] like Figure 1 and Figure 4As shown, the pipe cleaner support 8 includes two Y-shaped support rods spaced apart in the left-right direction, and the upper opening of the Y-shaped support rod supports the side of the horizontally placed pipe cleaner. This type of support is simple in design, easy to clean, maintain and replace, and is very suitable for use in the application scenario of the utility model.

[0044] In other implementations, two or more support rods are provided between the box partition and the corresponding box inner wall as brackets for supporting the pipe cleaner, and the support rods extend along the length direction of the box and are rotatably mounted on the box partition and the corresponding box inner wall. In this way, when the pipe cleaner rotates around its axis, the pipe cleaner and the support rods as brackets roll together, and due to the small friction force, the rotation of the pipe cleaner can be achieved under a small external force.

[0045] When in use, the pipe cleaner cleaning device is pushed to the ball receiving barrel position of the gas transmission pipeline, the two drain valves 13 on the side of the box are closed, and the neutralization cleaning liquid is added to the neutralization reaction chamber 7. After the pipe cleaner 4 is taken out, the fall chain 26 on the crossbeam 24 is adjusted to be retracted and extended, and the hook 27 is controlled to hang the ring of the pipe cleaner 4 and transport it to the neutralization reaction chamber 7. The reagent in the neutralization reaction chamber 7 reacts with the dirt such as hydrogen sulfide adhering to the pipe cleaner 4, which plays the role of neutralization and preliminary cleaning.

[0046] After reacting in the neutralization reaction chamber 7 for a period of time, the pipe cleaner 4 is driven by the hook 27 to move along the slide rail 25 to the cleaning chamber 6, and then the pipe cleaner 4 is placed horizontally on the pipe cleaner bracket 8, the pipe cleaner 4 lifting ring is connected to the connecting hook in the cleaning chamber 6, the box cover 3 is closed, the quick-release joint on the box cover 3 is connected to the high-pressure flushing pipeline, and the nozzle 18 on the spray pipe sprays flushing liquid in different directions. While flushing, the crank 9 on the side of the box body is shaken, so that the pipe cleaner 4 can be turned over and cleaned; after cleaning, the residual liquid in the two chambers of the box body 2 is discharged and recovered through the drain valve 13 at the bottom, and then the quick-release joint is connected to the high-pressure hot air pipeline, and the pipe cleaner 4 is dried by hot air, and it is turned over while blowing, so as to finally achieve the purpose of cleaning and drying the pipe cleaner 4.
