AI Technical Summary
In the existing technology, the scraper is only set on the inner wall near the top of the combustion tube, which fails to effectively cover the high-temperature combustion zone in the middle and lower part of the combustion tube, resulting in coal particles sticking together and coking, affecting heat transfer efficiency and the effective volume of the furnace.
A fluidized bed particle circulation device for controllable pyrolysis carbon deposition was designed. It uses a motor-driven rotating rod and a cleaning scraper on the top of a sealed cover. The rotating rod drives the cleaning scraper on the mounting base to contact the inner wall of the combustion chamber, scraping off residual materials and coking impurities. The impeller agitates the material to enhance the fluidization effect.
It achieves efficient cleaning of the inner wall of the combustion chamber, improves heat transfer efficiency and effective furnace volume, enhances material fluidization, and improves the cleaning efficiency of the cleaning scraper.
