[0030] Reflux mechanism. The reflux mechanism is used to reflux the excessively sulfur-containing gas in the detection box 3 for secondary treatment. The reflux mechanism is arranged at the lower end of the detection box 3. Figure 1As shown, the device solves the problem that the inner wall of the pipeline in the above-mentioned existing sulfur tail gas recovery device will be corroded when the pipeline is transporting sulfur gas, and long-term use will cause sulfur gas leakage to pollute the air, and the cost of using acid-resistant metal material transportation pipeline is high. The structure of the device is relatively simple, it is relatively quick and convenient to use, has high practicality, and has a relatively low production cost, which is easy to promote and use;

[0031] The clamping fixing mechanism includes a slide groove 13, a spring 14, a slider 15, a second clamping block 16 and a shifting block 17. The right end of the connecting pipe 2 is equidistantly provided with a slide groove 13, a spring 14 is arranged in the slide groove 13, and the spring 14 is slidably connected in the slide groove 13. The end of the spring 14 close to the second clamping groove 12 is fixedly connected to the second clamping block 16, and the end of the slider 15 close to the outer wall of the connecting pipe 2 is fixedly connected to the shifting block 17. Figure 8 As shown, this structure facilitates the rapid fixing of the anti-corrosion lining block 7 and the fixing block 9 to the inner wall and both sides of the connecting pipe 2, so as to protect the inner wall of the connecting pipe 2 and prevent the inner wall of the connecting pipe 2 from being damaged by sulfur corrosion.

[0032] The reflux mechanism includes a reflux pipe 5, a second stopper 20 and a second electric telescopic rod 21. The lower end of the detection box 3 is provided with a reflux pipe 5, the lower end of the detection box 3 is provided with a second stopper 20, the left end of the second stopper 20 is provided with a second electric telescopic rod 21, and the reflux pipe 5 is provided with an air pump body 23.

Figure 5As shown, this structure facilitates sealing the opening of the return pipe 5 to prevent gas from flowing out from the gap between the two when the second stopper 20 is not opened.

[0037] The working principle of the utility model is as follows: when in use, the anti-corrosion lining block 7 is first inserted into the inner wall of the connecting pipe 2, and is tightly attached to the inner wall of the connecting pipe 2, and then the fixing block 9 is brought close to the anti-corrosion lining block 7, so that the inserting block 11 at the left end of the fixing block 9 is inserted into the slot 22 at the right end of the connecting pipe 2, and at the same time, the first clamping block 10 is clamped and fixed in the first clamping groove 8, during which the first clamping block 10 undergoes elastic deformation, and during which when the inserting block 11 abuts against the second clamping block 16, the second clamping block 16 is forced to slide in the direction of the slide groove 13, so that the slider 15 slides in the slide groove 13, so that the spring 14 is compressed, and when the second clamping block 16 is aligned with the second clamping groove 12, the spring 14 rebounds to push the second clamping block 16 to be clamped in the second clamping groove 12 to fix the inserting block 11, and the After the desulfurization box 1, the connecting pipe 2, the detection box 3, the air outlet 4 and the reflux pipe 5 are connected and fixed, the gas is introduced from the left end of the desulfurization box 1 for desulfurization treatment, and then the treated gas continuously enters the detection box 3 for detection. When the sulfur content detection instrument body 6 detects that the sulfur content of the gas meets the standard, the first electric telescopic rod 19 is started to pull the first block 18 upward to open it, so that the gas is discharged from the air outlet 4. When the sulfur content is high, the second electric telescopic rod 21 is started to pull the second block 20 to the left to open it, and the air pump body 23 is started to make the gas flow back from the reflux pipe 5 to the desulfurization box 1 for secondary treatment. The gas flows under the internal pressure. The structure of the device is simple and easy to use and operate. The above is the entire working principle of the utility model.
