Efficient slag treatment device for high-temperature slag waste heat recovery

Abstract

The efficient slag treatment device comprises a conveying frame, a base and a first treatment box, the first treatment box is fixedly mounted at the top of the base, and a sealing plate is movably mounted on one side of the first treatment box; and a feeding hopper extending into the first treatment box is fixedly installed on one side of the sealing plate, a supporting frame is fixedly installed at the bottom of the interior of the first treatment box, and a vibration base is movably installed at the top of the supporting frame. Through mutual cooperation of a sealing plate, a feeding hopper and a vibration frame, heat on molten slag can be conveniently and rapidly dissipated, the waste heat recovery efficiency is improved, through mutual cooperation of an evaporation box, an evaporation chamber, an air suction pipe and a second treatment box, water in the evaporation chamber can be heated and evaporated, and the waste heat recovery efficiency is improved. And air in the air suction pipe can be continuously heated through the heat absorption disc, waste heat can be conveniently and fully utilized, and convenience is improved.

Description

technical field [0001] The invention relates to the technical field of high-temperature slag treatment, in particular to a high-efficiency slag treatment device used for high-temperature slag waste heat recovery. Background technique [0002] Slag refers to the vitreous non-metallic material coated on the surface of molten metal after iron ore is smelted, so as to separate it from the main metal. During steelmaking, the slag-forming flux added is fused with the oxidation products of impurity elements in the raw material. Slag is formed into slag. The converter steelmaking process is carried out in a molten reaction medium. Slag is the product of the fire steelmaking process, which is mainly composed of oxides in metallurgical raw materials or oxides generated in the metallurgical process. After the steel smelting is completed, due to the smelting temperature as high as several thousand degrees, the resulting molten slag will also bring out a lot of heat. Since the molten sla...

Problems solved by technology

[0007] The purpose of the present invention is to solve the shortcomings in the prior art, such as: the existing high-efficiency slag processing device for high-temperature slag waste heat recovery cannot When the slag is introduced, the temperature on the slag is quickly dissipated, which reduces the recovery efficiency. At the same time, when the slag is introduced, the material guide port is always open, and the heat emitted by the slag is easy to flow from the material guide port. Distributed to the air, resulting in the loss of heat recovery effect, it is inconvenient to recycle the heat energy of slag in a timely manner, resulting in the easy loss of waste heat of slag, the waste heat cannot be fully recovered, and the waste heat recovery effect is reduced. It is convenient to recycle the recovered waste heat, which reduces the utilization rate of resources. It is inconvenient to use the resources generated in the process of waste heat recovery to spray the slag, so that the slag will generate more dust when it is exported, and it is easy to affect the surrounding environment. , reducing the processing effect of the problem
