Description
Technical Field
The invention relates to an ice slurry cleaning method for a gas pipeline.
Background
Whether the gas pipeline purging is clean or not directly influences the safe operation and management of the gas pipeline network in the future. However, some gas pipelines have liquid discharged from the cylinder or the diffusing pipe shortly after production, and the discharged gas has a high content of sewage and rust. The reason for this analysis may be: firstly, the end of the pipe is not tightly sealed in the construction, the construction is not standard, and more water enters the pipe; secondly, the seamless pipe is rusted seriously; thirdly, the gas pipeline is not cleaned during construction.
After the gas pipeline is built, the gas pipeline is generally cleaned by adopting methods such as pipe network self-pressure purging, arranging a compressor for purging by adopting compressed air, adopting a blasting membrane method for purging, adopting a pipe cleaning and ball cleaning method and the like.
Several purging regimes are described below:
1. and purging by utilizing the self pressure of the pipe network. The method comprises the steps of firstly determining the position of pipeline blockage, closing a valve at the middle upstream of a pipeline network, diffusing fuel gas after the valve in the pipeline network, opening the upstream valve after the diffusion is finished, and determining the approximate position of the pipeline blockage by observing the reading of a pressure recording instrument in a pressure regulating cabinet connected behind the valve. After the approximate position of the pipeline blockage is determined, the medium-pressure end plug of the tail end pressure regulating cabinet is opened, the diffusing pipe is connected, the medium-pressure end valve of the pressure regulating cabinet is opened, and the blockage in the pipe network is discharged by using the working pressure of the pipeline fuel gas. In practice, the method for purging and cleaning the pipe by utilizing the self pressure of the pipe network is frequently used, and has the advantages of economy and quickness, and the defects that the self pressure of the gas pipe network is limited and the blockage in the pipe network cannot be purged completely.
2. In engineering practice, sometimes when the blocked pipeline cannot be purged completely by using a method of purging the pressure of the pipe network, a compressor can be arranged to pressurize air to purge the blocked object in the pipe network, but the highest pressure cannot exceed the strength test pressure of the pipeline. The method comprises the following steps: firstly, an upstream valve of the pipe network is closed, and fuel gas in the pipe network behind the valve is diffused. After the diffusion is finished, opening a medium-pressure plug of one pressure regulating cabinet at the downstream of the approximate blocking position, connecting a compressor, and connecting a medium-pressure end of one pressure regulating cabinet at the upstream of the approximate blocking position with a diffusion pipe. If there is no surge tank upstream of the substantially blocked position, bleed off can be provided by the bleed off line of the control valve. When the compressor is pressurized to a certain pressure, the valve of the diffusing pipe is opened to diffuse air, and after repeated pressurization and air discharge, the pipe cleaning requirement is met.
However, when the gas pipeline is purged, the used compressor has small displacement, low pressure and small volume of the gas storage tank, and the flow speed of the purge air in the pipe cannot reach the speed of taking away dirt (the flow speed is generally required to be more than 20 m/s).
3. The blasting purging is to seal one end of the purged pipeline with a blasting sheet with strength much lower than that of the pipeline, and to introduce compressed air into the other end. The air pressure in the system is gradually increased, when the pressure exceeds the limit pressure which can be borne by the rupture disk, the rupture disk is suddenly broken, and the compressed air in the system is instantly and rapidly expanded and is ejected out from the blast opening at a very high speed. Meanwhile, welding slag and other impurities in the pipeline are discharged under the vibration effect caused by blasting and the impact of high-speed airflow, and the blowing requirement can be met after repeated times. Even if the blasting membrane method is adopted for repeatedly purging, only the gas pipeline at the near end of the blasting opening can be purged completely, and the gas pipeline far away from the blasting opening cannot take away the sundries in the gas pipeline because the carrying capacity is weakened due to the reduction of the air velocity.
4. Spherical pig sweeping uses gas pressure to push the spherical pigs from the beginning to the end of the pipeline. The application condition of the spherical pig cleaning method is strict, the inner diameters of the cleaned pipelines are required to be consistent, the elbows of the pipelines need to be stamped elbows, the branch pipes of the pipelines cannot be welded in an inserting mode, and valves on the pipelines need to be ball valves. Because the condition of the pipe network is complicated and complicated, the applicable condition of the spherical pig cleaning method is difficult to achieve, and the pipe network is rarely used. The main purpose of the spherical pig is to remove accumulated liquid and separation medium in the pipe, and the effect of removing the block-shaped object is poor.
In view of the above, there is a need to develop a new method for cleaning a gas pipeline to solve the above problems.

As shown in fig. 1 to 5, the cleaning method of the gas pipe 1 of the present invention includes the steps of:
s1: providing a gas pipeline 1, ice slurry 2, a traction ball 3, a sponge column 8 with the radial width more than or equal to the diameter of the gas pipeline 1, a first connecting piece 4 and a second connecting piece 5;
the ice slurry 2 is also called fluidized ice and pumping ice, is composed of ice particles with the diameter not more than 1mm, is a solid-liquid two-phase flow formed by mixing the ice particles and water, shows a piston-shaped flow form, has various complex geometric shapes, and has the shearing force reaching 2-4 orders of magnitude of that of the water. The cleaning of the ice slurry 2 is to clean the pipeline by taking the ice slurry 2 as a medium, the ice slurry 2 has both liquid characteristic and solid characteristic, can adapt to various topological structures in the filled pipeline like liquid, and can generate larger friction force by collision and friction on the inner wall of the pipeline, so that the stability of sediments and attachments in the pipeline is damaged, and the sediments and the attachments are flushed out of the pipeline. The ice slurry 2 has large friction force, can well damage the stable result of sediments and attachments in the pipeline and has good cleaning effect; the ice slurry 2 is prepared from tap water and edible salt, is safe and environment-friendly, and does not cause any pollution to the environment; the ice slurry 2 has the liquid property, can adapt to various topological structures in the filling pipeline like liquid, and cannot be influenced by the inner diameter of the pipeline, a connector, an elbow, a valve and the like during actual cleaning; the pipeline does not need to be excavated, the operation is simple, the cleaning cost is low, and the time and the labor are saved.
In this embodiment, the ice slurry 2 may be manufactured on site or in advance, and is stored in the ice slurry storage tank 7 to be brought to the site.
The number of the provided sponge columns 8 is more than or equal to two, and the sponge columns 8 are connected through the first connecting piece 4.
S2: the traction ball 3 and the sponge column 8 are connected through a first connecting piece 4, the traction ball 3 and the ice slurry 2 are placed into the gas pipeline 1 from the first end of the gas pipeline 1, and the traction ball 3 and the ice slurry 2 are pushed to the second end from the first end of the gas pipeline 1 by using water pressure or high-pressure gas; the traction ball 3 is made of corrosion-resistant materials, and the traction ball 3 is a hollow sealed ball body, so that the traction ball 3 can pass through the gas pipeline 1 along with the ice slurry 2 and cannot stay in the gas pipeline 1. In the moving process of the ice slurry 2, the ice slurry can generate larger friction force by collision and friction on the inner wall of the gas pipeline 1, so that the stability of sediments and attachments in the gas pipeline 1 is damaged, the sediments and the attachments are loosened and fall off, and the ice slurry is discharged out of the gas pipeline 1 along with the ice slurry 2; at the same time, the traction balls 3 are also discharged from the gas pipe 1, and the traction balls 3 are recovered at the cleaning end.
S3: after the traction ball 3 is taken out, the first connecting piece 4 is pulled continuously to pull the sponge column 8 into the gas pipeline 1 until the sponge column 8 is pulled out from the second end.
The second connecting piece 5 is connected between the traction ball 3 and the first connecting piece 4, in the step S3, the second connecting piece 5 is pulled out first, and then the second connecting piece is stretched outwards continuously until the first connecting piece 4 drives the sponge column 8 to enter the gas pipeline 1. The lengths of the first connecting piece 4 and the second connecting piece 5 are more than or equal to the length of the gas pipeline 1. Since the gas pipeline 1 is not necessarily a straight pipeline, and there may be bending and the like, the first connecting piece 4 and the second connecting piece 5 are preferably connecting ropes, and the first connecting piece 4 is a thick rope and the second connecting piece 5 is a thin rope.
In this step, said second connector 5 only acts to pull the first connector 4 through the gas pipe 1, thus using a string. The second connecting piece 5 is used for pulling the sponge column 8 to penetrate through the gas pipeline 1, certain friction exists between the sponge column and the gas pipeline 1, the requirement on strength is high, and therefore a thick rope can be selected.
In addition, to increase the drying effect, the diameter or width of the sponge column 8 in the radial direction should be slightly larger than the diameter of the gas duct 1.
S4: after the sponge column 8 is taken out, detecting whether the sponge column 8 is dry or not, if so, removing the connection between the sponge column 8 and the first connecting piece 4, and taking out the first connecting piece 4; if not, the first connecting piece 4 is continuously pulled to pull the other sponge column 8 into the gas pipeline 1 and pull the sponge column 8 out from the second end, the operation is repeated until the pulled sponge column 8 is dry, the connection between the dry sponge column 8 and the first connecting piece 4 is released, and the first connecting piece 4 is taken out.
The water vapor in the gas pipeline 1 may not be completely adsorbed only by one-time drying of the sponge column 8, so that the operation can be repeated for many times until all the water in the gas pipeline 1 is adsorbed. According to experience, all water can be adsorbed through the gas pipeline 1 by passing through the sponge column 8 for 3-5 times.
S5: placing a detection sample plate 9 at one end of the gas pipeline 1, introducing high-pressure gas into the other end of the gas pipeline, continuing for a period of time, judging whether rust, dust or impurities exist on the detection sample plate 9, and if so, repeating the steps S2-S5; if not, cleaning is finished.
The detection sample plate 9 is a white cloth or white paint wood target plate, and rust, dust or impurities blown out can be more easily seen. The duration of the introduction of high-pressure gas is determined by the volume of the gas pipeline 1.
The high-pressure gas in steps S1 and S2 and S5 is supplied by the blower 6 or the air compressor. In addition, tap water may be introduced in step S2.
According to the cleaning method of the gas pipeline 1, the gas pipeline 1 can be cleaned and dried without excavating the gas pipeline 1, and the operation is simple; draw ball 3 to drive sponge post 8 through setting up and get into gas pipeline 1 to adsorb the aqueous vapor in the gas pipeline 1, can not influence gas pipeline 1's use, just sponge post 8 can used repeatedly, save material.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is specific and detailed, but not to be understood as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
