Description
Technical Field
The invention belongs to the technical field of ceramsite firing, and particularly relates to a vertical trumpet inner heat ceramsite firing device and a using method thereof.
Background
Biomass is considered to be an overlooked energy source and has the characteristics of ubiquity, richness, renewability and the like. The efficient development and utilization of biomass energy play a very positive role in solving the problems of energy and ecological environment. Although the biomass briquette fuel with more applications has the characteristics of low cost, convenient processing and the like, compared with the biomass micron fuel, the biomass briquette fuel has the defects of insufficient combustion, low combustion temperature, easy generation of a large amount of smoke and the like, and the biomass micron fuel has smaller particle size and is more fully contacted with air, so that the combustion speed and the efficiency are greatly improved, and further, higher combustion temperature can be obtained, and the application prospect of the biomass micron fuel is wider. The Xiaobo professor of Huazhong university of science and technology and the team thereof refer to the micron fuel with the particle size of less than 250 microns, which is efficiently produced by biomass, as the trumpet creeper fuel, and the trumpet creeper fuel can realize the combustion at the high temperature of more than 1400 ℃, so that the Chinese trumpet creeper fuel has wide market prospect.
According to statistics, the firing temperature of the conventional ceramsite is 1000-1200 ℃, and most of the main heat sources are fossil fuels. However, the ceramsite firing system using fossil fuel as a heat source has serious environmental pollution and is not beneficial to sustainable development of the environment, and the prior ceramsite firing system adopts large-scale firing equipment such as a rotary kiln, has serious heat energy loss and is not beneficial to reasonable utilization of resources. The ceramsite firing method adopting the vertical ceramsite firing device and taking the biomass as the heat source is beneficial to reasonable utilization of heat energy, particularly conforms to the current clean energy utilization form, and makes a contribution to sustainable development of the environment. However, the small-sized ceramsite firing device using biomass as a heat source is less applied to actual industrial production in China at present.
