Description

Technical Field

[0001] The present invention relates to a production device for titanium sponge, and particularly to a heating device for a reactor in the production of titanium sponge. Background Art

[0002] In industrial production of titanium sponge, the magnesium reduction method of titanium tetrachloride is adopted, and most of the furnace types adopt the combined method of inverted "U" type production, which is characterized by large single furnace output, high premium product rate and low energy consumption.

[0003] Its production is divided into two stages: reduction and distillation. In the reduction stage, magnesium reduces titanium tetrachloride in a reduction furnace, and a large amount of heat is released during production to generate titanium and magnesium chloride. In the distillation stage, magnesium and magnesium chloride in the reduction furnace are distilled into the cold end system to obtain pure titanium sponge. For the reactor in the cold end system, before entering the system for production, it is necessary to ensure that there is no moisture in the reactor, otherwise it will affect the product quality. In the existing technology, before the reactor in the cold end system is assembled, the reactor is at room temperature and there is a small amount of chloride adhering to the inner wall, which is easy to absorb moisture in the air and affects the product quality during production. Now a heating device for a reactor in the production of titanium sponge is provided to improve the product quality. Summary of the Invention

[0004] The present invention is to solve the technical problem that there is a small amount of chloride adhering to the inner wall of the cold end reactor at room temperature and it is easy to absorb moisture in the air.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions: A heating device for a reactor in the production of titanium sponge, mainly connected by the lower flange of the reactor and a flange, and a gasket is provided between the lower flange of the reactor and the flange; An inner cylinder and an outer cylinder are provided below the flange. The inner cylinder and the outer cylinder are of a structure with an open upper part and a sealed bottom, and a heat insulation layer is provided between the inner cylinder and the outer cylinder; An air inlet pipe is provided at the lower side of the cylinder body, and a valve A is provided on the air inlet pipe; A temperature measuring pipe and an air discharge pipe are provided at the upper part of the cylinder body, and a pressure gauge and a valve B are provided on the air discharge pipe; The pressure gauge is at the front end of the valve B.

[0006] The beneficial effects of adopting the above technical solutions are: 1. When the present invention is used in the distillation production of titanium sponge, it realizes the drying of the reactor, avoids the occurrence of moisture absorption phenomenon, and ensures the production quality of titanium sponge.

[0007] 2. The structure of the present invention is simple and easy to operate. Brief Description of the Drawings
