Chlorine feeding device of fluidizing chlorination furnace

Abstract

The invention relates to a chlorine feeding device of a fluidizing chlorination furnace. The chlorine feeding device comprises a chlorine primary distribution pipe, and the chlorine primary distribution pipe comprises a chlorine inlet, two treatment ports and at least two chlorine outlets. A chlorine outlet is connected with a chlorine secondary distribution pipe through a stop valve. Two sides ofthe chlorine secondary distribution pipe are respectively provided with a plurality of chlorine tertiary distribution pipes which are uniformly distributed. A third-stage chlorine distribution pipe is communicated with the second-stage chlorine distribution pipe and is arranged in the horizontal direction, a plurality of chlorination furnace connecting pipes arranged in the vertical direction arearranged at the top of the third-stage chlorine distribution pipe, and a plurality of dredging pipes arranged in the vertical direction are arranged at the bottom of the third-stage chlorine distribution pipe. The gas inlet uniformity of the fluidized bed can be guaranteed, long-term normal and stable operation of the chlorination furnace is guaranteed, and the device has the characteristics of uniform chlorine distribution, efficient fault treatment, convenience in maintenance, disassembly and assembly and the like.

Description

technical field [0001] The invention relates to the technical field of chlorination furnaces, in particular to a chlorine gas feeding device for a boiling chlorination furnace. Background technique [0002] In the process of preparing titanium tetrachloride by boiling chlorination of titanium slag, since titanium slag and petroleum coke contain a small amount of metal impurities (calcium oxide, manganese oxide, magnesium oxide, etc.), the products of impurity chlorination reaction calcium chloride, magnesium chloride, chloride The boiling point of manganese is above 1200°C, which is higher than the chlorination reaction temperature. It will be enriched in the fluidized bed during the production process. When the local reaction temperature of the bed drops, it will cause the high boiling point to solidify, bond the bed material, and block Chlorine gas distribution holes or pipes will destroy the fluidized reaction layer, so that the normal production of chlorination cannot be...

AI Technical Summary

Problems solved by technology

This structure has the following problems during production: 1. The flow rate of chlorine gas is uneven, which affects the effect of fluidization reaction; when the fluidized bed material starts to stick, it cannot be controlled and treated in a timely manner by area, or the treatment effect is not good; when maintenance needs to be disassembled, The integrated chlorine gas distributor is bulky and difficult to disassemble
