Description

Technical Field

[0001] The invention relates to the technical field of gas pipelines, in particular to a dehydrator driving device for a pipeline in a blast furnace pressure regulating valve group. Background Art

[0002] Coal gas is transported through pipelines. As the temperature drops along the way, the saturated water in the gas is continuously converted into mechanical water, condensed and gathered at the bottom of the pipe, and collected and discharged through the pipeline drainer. This method can only remove part of the mechanical water in the coal gas. The saturated water content of the coal gas increases with the increase of temperature. When installing the gas pipeline and the dehydrator, the pipelines are often spliced ​​and combined with each other through flanges to connect the gas pipeline and the dehydrator for assembly.

[0003] When currently installing pipelines with dehydrators, flanges are often required to splice and sew the pipelines together, and a large number of screws are used to fix them. This method not only has a complicated operation process during installation, but also causes many inconveniences for subsequent disassembly, reducing the convenience of pipeline installation; after the flue gas enters the dehydrator, the kinetic energy of the water droplets and the adhesion of the flue gas are relatively large, making it difficult to separate and filter each other, so that the dehydration work in the device is not ideal, and too much flue gas adheres to the surface of the water liquid and is easily accumulated in the device, making it impossible for the flue gas to circulate normally, increasing the limitations of the use of the dehydrator and reducing the separation efficiency of the water liquid and flue gas; when the dehydrator is separated from the pipeline, the flue gas entering the dehydrator has no storage space and is easily discharged directly to the outside, which affects the external working environment and increases the difficulty and inconvenience of using the device.
