The inflowing liquid is viscous, and the scraping of the two scrapers 211 can prevent the liquid from sticking to the inner wall of the first pipe 2.

[0041] The two first springs 210 are movably embedded in the two first sleeve rods 207 , respectively. The elastic force generated by the two first springs 210 pushes the two slide plates 208 .

[0042] like Figure 1-6 As shown, one side of the two scrapers 211 is movably embedded in the inner wall of the first pipe 2, and one side of the two first springs 210 is fixedly arranged on the opposite side of the two slide plates 208, respectively, and the two scrapers 211 can move.

[0043] like Figure 1-6 As shown, a sealing plate 301 is movably embedded on a side of the first pipe 2 away from the distributor 1 , and a second pipe 3 is fixedly arranged on one side of the sealing plate 301 , so that gas and liquid can flow into the interior of the second pipe 3 .

[0044] like Figure 1-6 As shown, a notch 305 is opened on one side of the first pipe 2, and the sealing plate 301 is movably embedded in the notch 305. Inserting the sealing plate 301 into the notch 305 can prevent gas and liquid from flowing out.

At this time, the elastic force generated by the two second springs 310 resists the pressing plate 308, thereby completing the fixation of the leakage net 309. The fixation of the leakage net 309 The method is simple. When the gas and liquid flow into the first pipe 2, the rotating rod 203 can rotate due to the bearing. The gas and liquid drive the rotating rod 203 to rotate through the turbine blades 204, and further the ring sleeve 205 drives the multiple stirring plates 206 to rotate, stirring the gas and liquid so that the two are fully mixed together. The two slides 208 can slide inside the two first sets of rods 207. At this time, the elastic force generated by the two first springs 210 pushes the two slides 208, and further through the two second sets of rods 209, the two scrapers 211 are closely attached to the inner wall of the first pipe 2. The rotating rod 203 drives the two scrapers 211 to rotate through the two first sets of rods 207, so that the two scrapers 211 scrape the liquid attached to the inside of the first pipe 2, so that before the distributor 1 evenly distributes the gas and liquid, the gas and liquid are fully mixed together, reducing fluctuations and disturbances, and improving the stability of the gas and liquid. At the same time, it can prevent the liquid from sticking to the inner wall of the first pipe 2, thereby improving the operating efficiency and stability of the distributor 1.
