Blast furnace slag heat energy recycling system

Abstract

The invention discloses a blast furnace slag heat energy recycling system comprising a slag cylinder, a rotating assembly, a lifting assembly, a motor assembly, a pipe, a liquid metal pump assembly and a heat energy exchanger. The slag cylinder is used for containing blast furnace slag, the rotating assembly is arranged above the slag cylinder and used for absorbing heat energy of the blast furnace slag, the lifting assembly is located outside the slag cylinder and the rotating assembly and used for fixing the rotating assembly and controlling the rotating assembly to ascend and descend in thevertical direction, the motor assembly is connected with the rotating assembly and provides power for horizontal rotation of the rotating assembly, the pipe contains liquid metal and is connected with the rotating assembly and used for conducting out the heat absorbed by the rotating assembly, the liquid metal pump assembly is connected with the pipe and provides power for circular flowing of theliquid metal in the pipe, after the liquid metal passes through the heat energy exchanger, heat energy in the liquid metal is transmitted out, and the temperature of the liquid metal is lowered. A planet rotating wheel combines rotation around the own axis and revolution, when the planet rotating wheel conducts revolution, the blast furnace slag is stirred, and it is ensured that the heat in theslag is fully absorbed, and when the planet rotating wheel rotates around the own axis, the blast furnace slag is prevented from adhering to the planet rotating wheel.

Description

technical field [0001] The invention relates to the technical field of recycling waste heat of blast furnace materials, in particular to a blast furnace slag heat recovery system. Background technique [0002] In the process of product manufacturing in some industries, a large amount of industrial heat radiation is often generated, such as the non-ferrous metal industry. [0003] The non-ferrous metal industry provides important basic raw materials for the development of the national economy, and is a resource-intensive industry that consumes a lot of energy and resources. In the production of non-ferrous metal products, a large amount of waste is also discharged, causing serious pollution to the environment. Although the non-ferrous metal industry is a large energy-consuming and pollutant-discharging household in the national economy, it is also one of the industries with great potential for energy-saving and emission-reduction. Among them, the recovery and utilization of...

Problems solved by technology

[0004] Blast furnace slag is a by-product formed by the gangue in the ore, ash in the fuel and non-volatile components in the flux during the blast furnace smelting process. It is a high-quality heat resource. If the waste heat is not recovered, it will be It causes waste of energy, and the scheme of using heat radiation absorbing materials to absorb industrial heat radiation often reduces its service life greatly when it encounters the blast furnace environment, which also results in poor efficiency of waste heat recovery
