[0019] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-4 The device shown is a pretreatment device for ultra-low concentration gas transportation, including a first connecting pipe 1 and a second connecting pipe 101. A connecting shell 2 is fixedly connected between the first connecting pipe 1 and the second connecting pipe 101, and a processing module 3 is provided inside the connecting shell 2.

[0021] The processing module 3 includes a filter plate 304 fixedly connected to the inside of the connecting shell 2. A cleaning rod 305 is provided on the surface of the filter plate 304, and a protective component is provided on the inside of the connecting shell 2.

[0022] Specifically, the gas is conveyed from the first connecting pipe 1 to the second connecting pipe 101. During this process, particulate impurities in the gas can be filtered through the filter plate 304. The surface of the filter plate 304 can be cleaned by setting the cleaning rod 305 to avoid clogging and affecting the passage of gas.

[0023] like Figures 1-4 As shown, the protective assembly includes a connecting block 301 fixedly connected inside the connecting shell 2. The connecting block 301 has a drive cavity inside. A rotating shaft 309 is rotatably connected to the inner wall of the drive cavity. One end of the rotating shaft 309 passes through the connecting block 301 and the filter plate 304 in sequence and is fixedly connected to the surface of the cleaning rod 305. A drive blade 307 located inside the drive cavity is fixedly connected to the surface of the rotating shaft 309. The surface of the connecting block 301 has annularly distributed through holes 306.

[0024] A rotating ring 317 is rotatably connected inside the connecting block 301. A connecting hole 308 communicating with the through hole 306 is opened on the surface of the rotating ring 317. A slide rod 313 is fixedly connected to the surface of the rotating ring 317 and slidably connected to the inner wall of the connecting block 301. A through hole 314 is opened on the surface of the slide rod 313. A fixing block 315 is fixedly connected between one side of the slide rod 313 and the inner wall of the connecting block 301. The fixing block 315 is a paraffin material component.

[0025] A spring 316 is fixedly connected to the surface of the slide bar 313. The other end of the spring 316 passes through the fixing block 315 and is fixedly connected to the inner wall of the connecting block 301. The spring 316 is in a stretched state.

[0026] Under normal conditions, the fixing block 315 of the paraffin material component is in a solid state and can fix the position of the spring 316. When combustion occurs during gas transportation, the flame burns along the gas transportation path. The heat from the flame can heat the fixing block 315 through the connecting block 301, causing the fixing block 315 of the paraffin material component to melt into a liquid state. At this time, the spring 316 can drive the slide rod 313 to move along the inner wall of the connecting block 301 under its own elastic force, thereby driving the rotating ring 317 to rotate. At this time, the position of the connecting hole 308 can be adjusted so that the connecting hole 308 is not connected to the through hole 306, thereby blocking the flame. The through hole 314 opened on the surface of the slide rod 313 is used for the liquid paraffin material to pass through during the movement of the slide rod 313.

[0027] like Figures 1-4 As shown, the upper surface of the rotating ring 317 has two notches 312, and the lower surface of the rotating ring 317 has a discharge hole 311 that communicates with the drive cavity.

[0028] The surface of the connecting shell 2 is provided with a water inlet pipe 302 and an installation pipe 303. One end of the water inlet pipe 302 and the installation pipe 303 respectively penetrates the connecting shell 2 and the connecting block 301 and is connected to two notches 312 respectively. The surface of the connecting shell 2 is provided with a drain pipe 310 connected to the discharge hole 311. The installation pipe 303 is provided with a one-way valve inside.

[0029] Under normal conditions, water is injected into the drive chamber through the inlet pipe 302, which drives the drive blade 307 to rotate the shaft 309, thereby driving the cleaning rod 305 to clean the surface of the filter plate 304. The water entering the drive chamber can be discharged through the discharge hole 311 and the drain pipe 310. When combustion occurs inside the second connecting pipe 101, causing the rotating ring 317 to rotate, the discharge hole 311 and the drain pipe 310 become misaligned. At this time, the water can gradually fill the interior of the drive chamber. The heat generated by combustion can be exchanged with the water. The water after heat exchange is discharged through the installation pipe 303 to avoid overheating and ignition of the gas in the first connecting pipe 1.

[0030] Working Principle: Under normal conditions, the fixing block 315 of the paraffin material component is in a solid state, which can fix the position of the spring 316. When combustion occurs during gas transportation, the flame burns along the gas transportation path. The heat from the flame can heat the fixing block 315 through the connecting block 301, causing the fixing block 315 of the paraffin material component to melt into a liquid state. At this time, the spring 316 can drive the slide rod 313 to move along the inner wall of the connecting block 301 under its own elastic force, thereby driving the rotating ring 317 to rotate. At this time, the position of the connecting hole 308 can be adjusted so that the connecting hole 308 is not connected to the through hole 306, thus... To block the flame, water is injected into the drive chamber through the water inlet pipe 302 under normal conditions, which drives the drive blade 307 to rotate the shaft 309, thereby driving the cleaning rod 305 to clean the surface of the filter plate 304. The water entering the drive chamber can be discharged through the discharge hole 311 and the drain pipe 310. When combustion occurs inside the second connecting pipe 101, causing the rotating ring 317 to rotate, the discharge hole 311 and the drain pipe 310 are misaligned. At this time, the water can gradually fill the interior of the drive chamber. The heat generated by combustion can be exchanged with the water. The water after heat exchange is discharged through the installation pipe 303 to avoid overheating and ignition of gas in the first connecting pipe 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
