Embodiment 1

[0026] Apply the boiling chlorination furnace with temperature control device of the present invention and use high titanium slag as raw material to carry out boiling chlorination.

[0027] When the furnace is started, the chlorination furnace is heated by the heating resistance wire 3. When the temperature measured by the thermocouple 2 reaches 1000° C., high titanium slag and coke are added in a ratio of 3:1, and the reaction starts. At this time, the heating of the resistance wire 3 can be stopped, or the heating power can be reduced. When the heat in the furnace decreases sharply due to unstable feeding or slag discharge, restart the heating of the resistance wire 3 to maintain the balance of heat in the furnace and the stability of the temperature. , to ensure the smooth operation of the chlorination furnace.

Embodiment 2

[0029] Apply the boiling chlorination furnace with temperature control device of the present invention and use titanium carbide as raw material to carry out boiling chlorination.

[0030] When the furnace is started, the chlorination furnace is heated by the heating resistance wire 3, and when the temperature measured by the thermocouple 2 reaches 500°C, titanium carbide is added and chlorine gas is passed through, and the reaction begins. At this time, the heating of the resistance wire 3 can be stopped, or the heating power can be reduced. When the heat in the furnace decreases sharply due to unstable feeding or slag discharge, restart the heating of the resistance wire 3 to maintain the balance of heat in the furnace and the stability of the temperature. , to ensure the smooth operation of the chlorination furnace.

Abstract

The invention discloses a chloride boiling furnace with a heating device and a corresponding temperature control method, comprising a heating device and a temperature measuring device, which is characterized in that: the chloride boiling furnace facilitates to control environmental temperature of the chlorination reaction; the heating device is arranged on the wall of the chloride boiling furnace and adopts the resistance wire which is even distributed in the wall of the furnace; the temperature measuring device adopts a thermocouple which is protected by bushing. When using the chloride boiling furnace, the temperature control method is that: the adding material is heated by heating device to reaction temperature firstly; different adding material temperatures are adopted according to the different chloride materials which is high-titanic slag or titanium carbide; and then the normal temperature of the chloride boiling furnace in running is controlled through monitoring the thermocouple and making-breaking the resistance wire. The chloride boiling furnace has the advantages of simple and easy practice, convenient manufacture, low cost, being able to control the temperature in the furnace conveniently and accurately, being suitable for controlling the running temperature in small chloride boiling furnace particularly and applying in the preparing of the titanium tetrachloride field mostly.

Description

technical field [0001] The invention relates to a temperature control device and method of an industrial fluidized chlorination furnace, in particular to a temperature control device and method of a fluidized chlorination furnace for preparing titanium tetrachloride by using titanium-containing raw materials. Background technique [0002] In the production process of preparing titanium tetrachloride in the boiling chlorination furnace, the reaction temperature control of the boiling section is the key technology in the whole process. The means by which measurements are made to indirectly control the temperature of the reaction environment in the furnace chamber. [0003] The currently used boiling chlorination furnace without heating equipment needs to place the entire chlorination furnace in the heating furnace to heat before starting the furnace, and then it can start feeding and reacting. The main problems in the production are: 1. Fuel needs to be added to heat the furn...
