R＆D of Monitoring System for Industrial Production Process
|
Nowadays, the digital transformation of the manufacturing industry has attracted great attention. One of the reasons is that digitization is likely to achieve high-profit manufacturing. In other words, in the process of transformation and upgrading of the manufacturing industry, the Internet of Things is used to connect all the contents of the enterprise’s production process, and CPS can instantly grasp the situation of the production chain, such as the production process in factories, logistics and sales channels. By analyzing these data information, we can accurately locate the current production status, such as "where there is waste" and " where to improve", so as to find solutions, predict future needs, and ultimately continue to improve competitiveness.

Technology and equipment of crude arsenic purification
|
In this project, the arsenic-containing dust produced by the non-ferrous smelting industry was taken as the main research object, and a new technical route was proposed, that is, taking the migration and transformation of arsenic as the main line, through the whole process, and according to the principle of "reduction, harmlessness and resource utilization", the new equipment for continuous reduction of calcium arsenate to prepare metal arsenic was developed mainly around the process route of "acid leaching of arsenic, purification of crude arsenic, lime fixation of arsenic and roasting reduction",and the reduction, harmlessness and resource utilization of arsenic-containing dust were realized.

Simulation of continuous oxygen-enriched side-blown electrothermal melting equipment
|
In this project, the actual furnace parameters are numerically simulated to explore the variation of melt, velocity, pressure, temperature and oxygen distribution in the smelting process. Firstly, the physical model of side-blowing furnace is established, and then the accuracy of the physical model is verified according to the parameters of water. Secondly, according to the relevant parameters of the existing melt and oxygen-enriched air, the distribution law of velocity in the furnace and the proportion of melt gas in the melting process is studied. Finally, according to the influence of single / double tuyere injection, oxygen lance flow rate and molten pool depth on the gas-liquid mixing process in the molten pool, the influence of oxygen lance arrangement, flow rate and molten pool depth on the velocity field at different positions in the molten pool is analyzed, and then the gas-liquid flow characteristics in the side-blown molten pool are summarized, so as to put forward suggestions for the design and layout of oxygen lance in the side-blown furnace.
