After the raw coal is ground into the pulverized coal by the coal mill, it flows in the pipeline in the form of fluid, and is transported to the furnace through the coal conveying pipeline. After a period of operation, the inner wall of the pipeline is severely eroded and worn by pulverized coal particles, and the wall thickness becomes thinner. In the elbow, the pipe wall is even worn by the pulverized coal, polluting the environment and reducing the efficiency. In order to improve the wear resistance of the pipeline, the selection of suitable high-strength structural adhesive wear-resistant ceramic lining can well avoid the wear of the pipeline, protect the pipeline and prolong the service life of the pipeline.
Wear-resistant ceramic pipes are made of high-temperature-resistant and strong adhesive to stick alumina ceramic sheets on the inner wall of the pipes, and after heating and curing, a firm anti-wear layer is formed. More than 15 times the steel pipe. The service life of ordinary pipes is half a year to one year, and the service life of wear-resistant ceramic pipes can reach 5-10 years, which greatly reduces the number of equipment downtime and maintenance, and saves a lot of manpower and material costs for enterprises. It is a very cost-effective The anti-wear scheme of pulverized coal conveying pipeline.
The service life of the pulverized coal conveying pipeline lined with wear-resistant ceramics is greatly improved. The lined corundum ceramics have high hardness and are resistant to acid and alkali corrosion. , The lining is smooth and does not accumulate material.
