Abstract
The utility model relates to a device by utilizing the flying ash in an electric power plant to produce floating beads, which aims at solving the problems of the prior art that the combustion of coal produces a great amount of coal ash which cannot be effectively used, so not only the resource is wasted, but also the environment is polluted, the prior hydrometer method is adopted to separate the floating beads directly from the flying ash, the production efficiency and the yield are low, and the quality of the product is difficult to be controlled. The self-designed device by utilizing the flying ash to produce the floating beads adopts a method that the gas is used as a powder sending agent (flying ash), so the flying ash is directly sent into a combustion chamber. The flying ash is directly melted down in the high-temperature high-speed airflow produced by the gas and the pure oxygen inside the combustion chamber to become liquid drop so as to produce the floating beads. The flying ash is re-combusted, so the fly ash is converted to the floating bead with high added value. The production device and the production craftwork are very simple, the production efficiency is high, and the practicability is strong. Since the application of the floating beads is wide, the floating beads can be used as the packing of the plastics and rubber, the excellent heat-preservation material, the building material and the advanced composite material. Therefore, the device has promising market application prospect and promising industrialized prospect.
