Embodiment Construction

[0017] The embodiments are described below with reference to the drawings.

[0018] A kind of uniform distribution of chlorine gas to prevent clogging the bottom of boiling chlorination furnace. A support sleeve 5 is installed in the middle of the shallow cylindrical furnace bottom shell 7, and an isolation plate 3 is installed on the support sleeve 5. A number of pores are evenly distributed on the isolation plate 3, that is, pore distribution On concentric circles with the same spacing, the pore spacing on each circle is also the same. A chlorine gas distribution pipe 4 is installed in each air hole. The chlorine gas distribution pipe 4 is composed of a sleeve 4.1 and a swirl rod 4.2 that can be freely lifted and rotated in the sleeve 4.1. The casing 4.1 is fixed on the isolation plate 3 by welding or thermal expansion or welding combined thermal expansion. The upper surface of the swirl rod 4.2 has a spiral groove 4.22, the middle part of the swirl rod 4.2 has a baffle 4.23, an...

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...
