Waste gas treatment device for iron-containing steel scrap smelting

Abstract

The invention relates to the technical field of steel scrap smelting, and discloses a waste gas treatment device for iron-containing steel scrap smelting. The device comprises a collecting hopper, wherein a straight flue channel is fixedly mounted at the bottom of the collecting hopper and close to one side, a partition plate is fixedly mounted at the position of one side of the top of the straight flue channel and located in the collecting hopper, and an inductor is fixedly installed at the position, close to the bottom, of one side of the inner wall of the collecting hopper, the top of the inner cavity of the straight flue channel is movably sleeved with a rotating partition plate. According to the invention, a partition plate is fixedly installed at the position, located in a collecting hopper, of one side of the top of a straight flue channel so as to divide the inner cavity of the collecting hopper into two parts by the partition plate, the tops of the two parts communicate with each other, and when a furnace mouth bin door is opened, internal high-temperature airflow flows into the collecting hopper and cannot be in direct contact with an inductor under the blocking effect of the partition plate, so that the problems that high-temperature gas in the furnace directly makes contact with the inductor, the temperature of the high-temperature gas is too high, the high-temperature gas is opened too early or closed too completely, and induction is not sensitive are solved.

Description

technical field [0001] The invention relates to the technical field of scrap steel smelting, in particular to a waste gas treatment device for ferrous scrap steel smelting. Background technique [0002] In the smelting of scrap steel, the method of feeding materials in batches is generally adopted for smelting, which leads to the opening and closing of the door of the electric arc furnace mouth continuously, because the scrap steel in the furnace will generate a large amount of high-temperature waste gas during the smelting process As a result, every time the furnace door is opened, the high-temperature exhaust gas and smoke will be emitted from the furnace to the surrounding environment and cause pollution. Therefore, a waste gas treatment device will be installed at the furnace mouth. The traditional waste gas treatment device has a collection bucket to absorb Pipe and air pump, exhaust gas entering the interior of the collection bucket will be absorbed by the joint action...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the use of the existing waste gas treatment device for smelting ferrous scrap steel proposed in the background technology, the present invention provides a waste gas treatment device for smelting ferrous scrap steel, which is equipped with a pump that can be automatically started and stopped It solves the problem of waste of resources caused by the fact that the air pump is always running in traditional equipment
