Furnace bottom anti-clogging boiling chloridizing furnace with chlorine uniform distribution

Abstract

The invention relates to an evenly distributed chlorine anti-blockage boiling chlorination furnace bottom which can solve the problems of blockage of a sieve plate of the existing boiling chlorination furnace and channeling and dead zones of airflow, a support sleeve is arranged at the middle part of an outer shell of the furnace bottom, an isolation plate is arranged on the support sleeve, a plurality of chlorine distribution pipes are evenly distributed on the isolation plate, whirlpool rods which can ascend, descend and rotate freely are arranged in the chlorine distribution pipes, and an annular chlorine pipe is arranged in the outer shell of the furnace bottom. A fixed sleeve is arranged at the periphery of the isolation plate, and refractory fillers which consist of fireclay refractory materials containing 45 percent-70 percent silicon oxide are filled among the chlorine distribution pipes in the fixed sleeve. A slag discharge pipe is penetrated in the refractory fillers, the isolation plate and the middle part of the furnace bottom. The adoption of the boiling chlorination furnace bottom can lead chlorine to enter the chlorination furnace in the whirlpool form, form a stable flow layer in the furnace, realize the large-scale chlorination furnace and the stable operation, solve the problems of material leakage and blockage of the sieve plate and prevent the occurrence of channeling and dead zones.

Description

Technical field [0001] The invention belongs to equipment for preparing titanium tetrachloride, and particularly relates to a boiling chlorination furnace. Background technique [0002] Titanium tetrachloride is produced by boiling chlorination in a chlorination furnace using a powdered mixture of titanium-rich materials and carbon and chlorine in a fluidized state, which is a high-efficiency chlorination metallurgy technology. The chlorination furnace is the necessary equipment to realize boiling chlorination, and the key part of the normal production and operation of the chlorination furnace is whether the structure of the chlorination furnace bottom is reasonable. The bottom of the boiling chlorination furnace used for the production of titanium tetrachloride in China has two structural forms. One is the bottom of the chlorination furnace with a sieve plate and a distribution plate with a gas distribution plate installed at the cone bottom position above the chlorine pipe at t...
