AI Technical Summary

Technical Problem

The significant kinetic energy outside existing smelting furnaces is not being effectively utilized, resulting in energy waste.

Method used

Kinetic energy recovery components, including steel frame components and recovery components, are evenly arranged along the edge of the top surface of the smelting furnace. Horizontal airflow drives the impeller and generator components to convert kinetic energy into electrical energy. The airflow direction and speed are optimized by the guide components, and the orientation of the guide components is adjusted by the wind direction sensor to improve the recovery efficiency.

Benefits of technology

It effectively recovers and converts the kinetic energy of the horizontal airflow outside the smelting furnace, improves energy utilization efficiency, and reduces energy waste.

Abstract

This utility model relates to the field of industrial energy-saving technology, and in particular to a device and an electric arc furnace for recovering the kinetic energy of hot airflow outside a smelting furnace. The device includes at least one kinetic energy recovery component, which is fixedly installed on the top surface of the smelting furnace. Each kinetic energy recovery component includes a steel frame assembly and a recovery component. The bottom of the steel frame assembly is fixedly connected to the top surface of the smelting furnace, and the recovery component is installed on top of the steel frame assembly. It is driven by the horizontal airflow generated during the operation of the smelting furnace, which diffuses from the center of the high-pressure zone to the surrounding areas, thereby converting kinetic energy into electrical energy. In this way, the hot air outside the smelting furnace forms a high-pressure zone above the smelting furnace, which in turn forms a horizontal airflow that diffuses from the center of the high-pressure zone to the surrounding areas. The recovery components of each kinetic energy recovery component installed on the top of the smelting furnace generate electrical energy under the drive of this horizontal airflow to recover the kinetic energy contained in the horizontal airflow, thereby improving the energy utilization efficiency.
