AI Technical Summary

Technical Problem

When handling electric furnace waste gas, the smoking range of existing dust removal equipment is limited, causing smoke to mix directly into the air, affecting environmental quality, and at the same time, the heat energy consumption is large, and it needs to be used rationally.

Method used

An electric furnace exhaust gas treatment device for heat treatment is designed, including a side smoking pipe and a top smoking pipe. It blocks the diffusion of smoke and dust through the side guard plate, and absorbs heat using the heat exchange chamber and the cold pipe, collects high-temperature smoke and dust into the heat storage cylinder to reduce heat energy and dissipate heat.

Benefits of technology

The smoking range is improved, smoke and dust are avoided directly mixing into the air, environmental quality is ensured, and energy conservation and emission reduction are achieved through effective utilization of heat energy.

Abstract

The utility model belongs to the technical field of waste gas treatment of electric furnaces, particularly relates to a waste gas treatment device of an electric furnace for heat treatment, and aims to solve the problems of limited smoke suction range and high heat energy consumption of a dust removal hopper in the background technology. And side protection plates are welded to the outer walls of the two sides of the side smoke suction hopper. As the side smoke suction hopper and the top smoke suction hopper are respectively arranged on the side edge and the top of the electric furnace main body, and smoke diffusion is blocked by the side protection plate, the smoke suction range of the smoke suction hoppers is enlarged, the smoke is prevented from being directly mixed in the air, the smoke suction range is wide, and the quality of the surrounding environment is ensured; after high-temperature smoke enters the heat exchange bin along the smoke suction pipe, a medium in the cold pipe can enter the coil pipe to absorb heat, so that the high-temperature medium can be uniformly collected into the heat storage cylinder along the heat pipe, heat dissipation of heat energy is reduced, the heat energy is reasonably utilized, and the effects of energy conservation and emission reduction are achieved.
