Description

Technical Field

[0001] This utility model relates to the field of pipeline dredging technology, specifically to a device for dredging frozen steam pipelines. Background Technology

[0002] Steam pipelines are primarily used for transporting steam, a high-temperature, high-pressure form of energy. In industrial production, steam is commonly used to drive steam turbines, generators, and other equipment, converting it into electrical energy or other forms of mechanical energy. Steam pipelines are also frequently used in various heating and insulation applications. The high-temperature characteristics of steam make it an ideal choice for heating equipment, used for heating process media and maintaining stable equipment temperatures. In winter, steam pipelines can also be used for building heating to ensure comfortable indoor temperatures. In many chemical and processing processes, steam pipelines provide the necessary heat and reaction conditions. For example, in the petrochemical industry, steam is used to heat raw materials, promote chemical reactions, and perform distillation separation. The high-temperature sterilization effect of steam makes it an ideal tool for disinfection and cleaning. In industries such as medical and food processing, steam pipelines are often used for disinfecting equipment, pipes, and surfaces to ensure hygiene standards in the production environment.

[0003] When using steam pipelines in extremely cold weather, if the steam pipeline stops supplying gas and the water vapor inside the pipeline is not discharged in time, the pipeline is very likely to freeze, causing production to be paralyzed.

[0004] In response to the problem that steam pipelines are prone to freezing and condensation when they stop supplying gas in cold weather, causing pipeline blockage, there is an urgent need for a steam pipeline freezing and condensation clearing device. Summary of the Invention

[0005] This invention addresses the problem that steam pipelines are prone to freezing and condensation when gas supply stops in cold weather, causing blockages. It proposes a steam pipeline freezing and condensation clearing device that can clear frozen pipelines and ensure normal pipeline operation.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is a steam pipe freezing and unblocking device, comprising a gas source pipe and an unblocking pipe. The gas source pipe and the unblocking pipe are connected by an intermediate pipe. The air inlet end of the gas source pipe is connected to the steam pipe, one end of the unblocking pipe is the drain end, and the other end of the unblocking pipe is connected to the pipe to be unblocked. In use, the steam pipe is connected to the gas source pipe, and then the pipe to be unblocked is connected to the unblocking pipe. Steam is continuously supplied to the inside of the pipe to melt the freezing inside the pipe. After melting, the water is discharged through the drain end of the unblocking pipe, thus completing the unblocking of the frozen pipe. The overall effect is good and the practicality is strong.

[0007] Furthermore, quick connectors are used at both ends of the intermediate pipe to connect to the gas source pipe and the dredging pipe respectively, so as to facilitate quick connection of the pipes.

[0008] Furthermore, an external filter is installed at the drain end of the unblocking pipe. This external filter can filter the water discharged from the unblocking pipe, preventing pipe blockage.

[0009] Furthermore, a ball valve is installed on the gas supply pipeline, which can control the opening and closing of the gas supply pipeline.

[0010] Furthermore, the intermediate pipes are made of flexible pipes, which facilitates the connection of the pipes.

[0011] Furthermore, a thermometer and a pressure gauge are installed on the gas source pipeline, and a thermometer and a pressure gauge are installed on the dredging pipeline. The temperature and pressure inside the gas source pipeline and the dredging pipeline can be monitored through the thermometer and pressure gauge.

[0012] The beneficial effects of this utility model are: This device can utilize existing steam pipelines for unblocking operations, making it convenient to operate. Operators familiar with the on-site pipeline structure can quickly unblock the pipelines. At the same time, using this device does not require a large number of personnel to operate, and it can unblock frozen pipelines without the aid of an external air source, saving a lot of manpower, financial resources and operating time, and improving the efficiency of rapid production recovery.

[0016] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0017] like Figure 1 As shown in this embodiment, the steam pipe freezing and unblocking device proposed by this utility model includes a gas source pipe 1 and an unblocking pipe 4. A thermometer 2 and a pressure gauge 3 are installed on the gas source pipe 1, and a thermometer 6 and a pressure gauge 5 are installed on the unblocking pipe 4. These gauges allow for monitoring of the temperature and pressure inside the gas source pipe 1 and the unblocking pipe 4. A ball valve is installed on the gas source pipe 1 to control its opening and closing. The gas source pipe 1 and the unblocking pipe 4 are connected by an intermediate pipe 7. Both ends of the intermediate pipe 7 are connected to the gas source pipe 1 and the unblocking pipe 4 respectively using quick-connect couplings. These quick-connect couplings facilitate rapid connection of the pipes. The intermediate pipe 7 is a flexible pipe, which facilitates pipe connection. The air inlet end of the gas source pipe 1 is connected to the steam pipe. One end of the unblocking pipe 4 is the drain end, and an external filter is installed at the drain end of the unblocking pipe 4. The external filter can filter the water discharged from the unblocking pipe 4 to prevent pipe blockage. The other end of the unblocking pipe 4 is connected to the pipe that needs to be unblocked. In use, the steam pipe is connected to the gas source pipe 1, and then the pipe that needs to be unblocked is connected to the unblocking pipe 4. Steam is continuously supplied into the pipe to melt the condensation inside the pipe. After melting, the water is discharged through the drain end of the unblocking pipe 4, thus completing the unblocking of the frozen pipe. The overall use effect is good and the practicality is strong.

[0018] During operation, after locating the frozen pipeline, first connect the gas source pipeline 1 to the steam pipeline. Then, use quick connectors to connect the gas source pipeline 1 and the unblocking pipeline 4 respectively. Before connecting, open the drain outlet at the drain end of the unblocking pipeline 4 to drain the liquid water in the frozen pipeline and confirm that the pipeline and equipment are airtight. Ensure that the thermometers and pressure gauges on the gas source pipeline 1 and the unblocking pipeline 4 are functioning properly, and that the steam temperature does not exceed the thermometer range. For the frozen pipeline after draining the liquid water, the temperature should be the outdoor temperature and the pressure should be 0.1 MPa. Ensure that the temperature and pressure in the gas source pipeline 1 and the unblocking pipeline 4 are consistent with the parameters in the process flow equipment. Then, open the valves on both sides of the pipeline and use the high-temperature steam in the steam pipeline to unblock the frozen pipeline. During the unblocking process, [the following will occur]. The process involves three stages: Stage 1, the filling stage, where the temperature and pressure in the pipe continuously rise. When the pressure equals that of the steam pipe, it indicates the pipe is full of steam. Stage 2, the melting stage, where the pressure in the pipe begins to drop after equalizing with the steam pipe, indicating the frozen water in the pipe is slowly melting. At this point, the temperature in the pipe is lower than that in the steam pipe. Stage 3, the emptying stage, where the pressure changes from decreasing to increasing, indicates all the frozen water in the pipe has melted. The drain outlet at the drain end needs to be opened to empty the pipe. Finally, after confirming the frozen water has been completely drained, the drain valve is closed. When the temperature and pressure on both sides of the pipe are equal, the pipe valve can be closed, the hose and quick connector removed, and normal production operations resumed.
