Problems solved by technology

[0002] The production process of metal magnesium requires a high temperature of 1200°C. At present, the reducing slag containing a large amount of heat generated in the production process of metal magnesium is directly discharged and cooled, which not only causes the heat energy to not be fully utilized, but also wastes a lot of energy; up to now So far, there is no device that can fully replace and utilize the waste heat of reducing slag

Embodiment 1

[0013] Embodiment 1 The structure and function of each part of the water-cooled slag cooler of a metal magnesium reduction slag waste heat utilization system:

[0014] The slag cooler is composed of an outer cylinder 1, an inner cylinder 2, a slag feeding device 3, a slag discharging device 4, a power transmission device 5, an underframe 6, a water inlet and outlet device 7 and an electrical control system 8, and is characterized in that the The inner cylinder body 2 is made of graphite rod, and the cylinder body adopts a water-cooled wall structure. The outer cylinder 1 of the slag cooler is a metal structural unit, and a transmission device 5 is welded outside the outer cylinder. The inner cylinder 2 of the slag cooler is welded with fixed helical guide vanes 2-1, and slag lifting plates 2-2 are welded between the fixed helical guide vanes in the inner cylinder. The slag feeding device 3 of the slag cooling machine is composed of a slag feeding pipe 3-1, a sealing head 3-...

Embodiment 2

[0015] Example 2 Working process of a water-cooled slag cooler in a magnesium metal reduction slag waste heat utilization system:

[0016] The internal structure of the slag cooler is mainly composed of an outer cylinder 1 with a transmission device welded outside the cylinder and an inner cylinder 2 with a fixed helical guide vane 2-1 welded on the inner cylinder. The fixed helical guide vanes 2-1 in the inner cylinder are welded There is a slag lifting plate 2-2. When the slag cooling machine is slowly rotated by the transmission device 5, the high-temperature reduced slag is guided forward by the spiral blade 2-1 in the inner cylinder body 2. At the same time, when rotating, the slag lifting plate 2-2 drives The slag is lifted upwards, and when it reaches a certain height, it is thrown downwards, and the cooling water flows in the reverse direction in the jacket between the inner and outer cylinders to take away the exchanged heat, so that the high-temperature reduction sl...

Abstract

The invention relates to a water-cooling slag cooling machine of a metal magnesium reduction slag waste heat utilization system and particularly relates to a slag cooling machine which supplies gas for production and living by utilizing reduction slag waste heat to produce steam. The slag cooling machine comprises an outer cylinder 1, an inner cylinder 2, a slag inlet device 3, a slag outlet device 4, a power transmission device 5, a bottom frame 6, a water inlet and outlet device 7 and an electrical control system 8, and is characterized in that the inner cylinder 2 is produced by graphite rods, and each cylinder adopts a water-cooling wall type structure. The slag cooling machine provided by the invention mainly has the advantages that the inner cylinder adopts the graphite rods, so that the heat conduction efficiency is high; heat exchange is performed with dispersed slag while water cooling, so that the slag cooling effect is good; and the water consumption is low, and the slag cooling machine has no special requirements on water quality.

Description

technical field [0001] The invention relates to a slag cooler which fully utilizes the waste heat utilization system of metal magnesium reduction slag, in particular to a water-cooled slag cooler which fully utilizes the waste heat utilization system of metal magnesium reduction slag. Background technique [0002] The production process of metal magnesium requires a high temperature of 1200°C. At present, the reducing slag containing a large amount of heat generated in the production process of metal magnesium is directly discharged and cooled, which not only causes the heat energy to not be fully utilized, but also wastes a lot of energy; up to now So far, there is no device that can fully replace and utilize the waste heat of the reducing slag. Contents of the invention [0003] The invention overcomes the shortcomings of the prior art and provides a device capable of fully replacing and utilizing the waste heat of the reducing slag. The present invention is realized b...
