Description

Energy-saving equipment for metal silicon production Technical Field The utility model relates to the technical field of metal silicon production, in particular to energy-saving equipment for metal silicon production. Background In modern metal silicon production processes, blower systems are responsible for the vital air flow delivery function, providing the necessary aerodynamic forces for the production process. When silicon materials are smelted in an electric furnace, high-pressure air flow generated by the air blower is used for promoting combustion and oxidation reaction, accelerating material movement and improving production efficiency. However, these airflows carry a lot of heat energy after the completion of the work, and the temperature is usually up to 300-500 ℃, if the airflows are directly discharged to the external environment, precious energy resources are wasted, and the temperature of the production workshop is increased, so that the working environment is affected. Based on the concepts of energy conservation and environmental protection, a heat exchange system is generally adopted in the industry to recycle the heat in the part of air flow, and the heat is converted into plant heating or process heat, so that the energy utilization efficiency is remarkably improved. However, in practical application, it is found that the gas flow in the production process of metallic silicon contains a large amount of impurities such as silicon dust and carbon particles, and these solid particles are easily accumulated on the surface of the heat exchange equipment, so that the heat exchange efficiency is reduced, and the equipment is possibly blocked and damaged. Although each manufacturing enterprise is configured with a corresponding filtering system, the existing equipment has obvious defects in the structural design of the filter screen, so that maintenance personnel cannot conveniently check and replace the filter screen. In-depth analysis of prior art obstacles shows that the filtering device commonly used in metal silicon factories usually adopts a fixed installation structure, and a filter screen is fixedly connected with a shell through a sealing rubber strip and a plurality of bolts. When the filter screen needs to be replaced, maintenance personnel must shut down the whole system, and the ten or even tens of fixing bolts can be detached after waiting for equipment cooling, so that the whole process is time-consuming and tedious and the operation is complex. Even more troublesome is that the sealing rubber strip is often adhered to the metal component due to long-term exposure to high temperature environment, increasing the disassembly difficulty, sometimes even requiring forced separation by using special tools, which not only prolongs the maintenance time, but also may damage the equipment components. In the busy season, each equipment shutdown represents a huge economic loss, so that many enterprises have to prolong the filter screen replacement period, continue to use the filter screen with reduced efficiency, and reduce the heat energy recovery rate and increase the energy waste. Disclosure of utility model (One) solving the technical problems Aiming at the problems in the prior art, the utility model provides energy-saving equipment for producing metal silicon, which aims to solve the technical problems in the background art.
