[0024] In a preferred embodiment, the wear-resistant layer 9 is cast stone or ceramic sprayed, and the cast stone and ceramic material has very high hardness and wear resistance, and the wear-resistant layer 9 formed by spraying can effectively resist the scouring and friction of dust particles in the dust-containing gas, greatly improving the wear resistance of the pipeline elbow 3 part, prolonging the service life of the part and even the entire dust removal pipeline, reducing the frequent replacement of the pipeline due to wear, and reducing maintenance costs.

[0025] In a preferred embodiment, the pipeline body 1 is a Q235 coiled welded pipe, which has good strength and welding performance, providing a stable and reliable basic structure for the wear-resistant dust removal pipeline.

[0026] In a preferred embodiment, the thickness of the pipe body 1 is 7-9 mm, which can make the pipe body 1 have good economy while having sufficient strength. It can withstand the pressure generated by the flow of dust-containing gas in the pipe, and will not be too thick to cause high cost. At the same time, the appropriate thickness is also conducive to better cooperation with the wear-resistant layer 9, and together guarantees the service performance and service life of the pipe.

[0027] In a preferred embodiment, the wear-resistant layer 9 has an inner diameter wear-resistant end 7 near one end of the axis of the elbow pipe 3, and an outer diameter wear-resistant end 8 away from the other end of the axis of the elbow pipe 3. The thickness of the wear-resistant layer 9 gradually increases from the inner diameter wear-resistant end 7 to the outer diameter wear-resistant end 8. The gradual thickness design fully considers the difference in wear degree at different positions of the elbow pipe 3. Near the axis of the elbow pipe 3, the airflow speed is relatively slow but the scouring force is concentrated, and a relatively thin thickness can also meet the wear-resistant requirements and save materials. Away from the axis, the airflow speed is fast and the impact force is large, and a relatively thick wear-resistant layer 9 provides stronger wear-resistant protection. Thus, the structure of the wear-resistant layer 9 is optimized, and the wear-resistant performance of the elbow pipe 3 is more effectively improved.

[0028] In a preferred embodiment, the thickness of the inner diameter wear-resistant end 7 is 6-8 mm, and the thickness of the outer diameter wear-resistant end 8 is 10-12 mm, which further improves the wear resistance and pertinence of the wear-resistant layer 9. The 6-8 mm thickness of the inner diameter wear-resistant end 7 can meet the relatively small wear requirement of the inner side of the elbow pipe 3; the 10-12 mm thickness of the outer diameter wear-resistant end 8 can enhance the protection ability of the more serious wear on the outer side of the elbow pipe 3, so that the layout and thickness setting of the wear-resistant layer 9 are more scientific and reasonable, and the protection effect of the wear-resistant layer 9 is greatly improved.

[0029] In a preferred embodiment, the slope of the first ring slope surface 5 is 28-32°, which can make the dust-containing airflow smoothly transition when entering the elbow pipe 3 from the first straight pipe 2. This angle will not make the airflow transition too slow to reduce efficiency, nor will it cause airflow turbulence due to too large an angle, thereby effectively reducing the impact and wear of the airflow on the first end of the wear-resistant layer 9, ensuring the integrity and stability of the wear-resistant layer 9 and prolonging its service life.

[0030] In a preferred embodiment, the slope of the second ring slope surface is 28-32°, which can also keep the dust-containing airflow in a smooth flow state when entering the second straight pipe 4 from the elbow pipe 3. A reasonable slope range helps to reduce the erosion of the airflow on the second end of the wear-resistant layer 9, further improving the durability of the wear-resistant layer 9 and ensuring the stable operation of the entire composite material wear-resistant dust removal pipe at the junction of different parts, effectively reducing wear and damage caused by airflow impact.

[0031] The principle and implementation mode of the utility model are described by applying specific examples, and the above embodiment is only used for helping to understand the method and core idea of the utility model; meanwhile, for the general technical personnel in the field, the specific implementation mode and application range will be changed according to the idea of the utility model. In conclusion, the content of the specification should not be understood as the limitation of the utility model.
