AI Technical Summary

Technical Problem

Existing water-cooled furnace covers cannot effectively purify harmful gases during the steelmaking process, leading to environmental pollution and health risks. At the same time, they cannot recover and utilize high-temperature heat energy, resulting in resource waste.

Method used

A water-cooled furnace cover including an air purification mechanism and a heat recovery mechanism was designed. It uses an air quality sensor and a solenoid valve tube system to purify harmful gases and recovers heat energy through a heat absorption plate and heat exchange tubes.

Benefits of technology

It achieves effective purification of harmful gases, prevents their spread, ensures the health of operators, and recovers and utilizes the high-temperature heat energy generated during steelmaking, thereby improving resource utilization.

Abstract

The present application relates to the technical field of water-cooled furnace cover, especially relates to a device for prolonging the service life of a LF furnace water-cooled furnace cover and a use method thereof.The technical scheme comprises a cover, an air purification mechanism and a heat energy recovery mechanism, the heat energy recovery mechanism is fixedly installed on the other side of the top of the cover, the heat energy recovery mechanism comprises a recovery box, heat exchange pipes are spirally installed in the recovery box, and the heat exchange pipes extend out, and water inlets and outlets are respectively installed on the two sides of the recovery box.The heat absorption plate absorbs the heat in the cover, heat exchange is realized, the cover is cooled, the hot water after heat absorption is transported to the cooling box through the circulating pipe, the heat exchange pipes are heated by the hot water in the cooling box, the water source in the recovery box is heated by the heat conduction performance of the heat exchange pipes, and the heat in the cover is recycled by the water source exchange temperature in the heat exchange pipe recovery box.
