Integrated furnace bottom for producing titanium tetrachloride by chlorination furnace

Abstract

The utility model discloses an integrated furnace bottom for producing titanium tetrachloride by a chlorination furnace. The integrated furnace bottom comprises a distribution pipe, a circular furnacebottom flange, a pull groove, a circular feeding disc, an air inlet, a blocking cap, a slag discharging pipe, a blind plate and a blocking plate; the circular feeding disc is arranged below the circular furnace bottom flange, holes are formed in the surface of the disc, a blocking plate is arranged on the circumferential surface of the disc, and an air inlet is formed in the blocking plate; one end of the distribution pipe penetrates through the furnace bottom flange and the feeding disc, and the blocking cap is arranged at an end opening; the distribution pipe is welded on the circular furnace bottom flange; the pull groove is formed in the lower part of the distribution pipe and is formed in the circular feeding disc; the slag discharging pipe is arranged in the center of the bottom ofthe circular furnace bottom flange. According to the invention, a chlorine feeding tray and the furnace bottom of the chlorination furnace bottom technology are combined, and the feeding tray and thefurnace bottom are connected into a whole, so that the sealing points are reduced, the leakage risk caused by poor sealing at each distribution pipe is eliminated, and the environmental protection capability is improved; the problem that the chlorine feeding disc is high in manufacturing cost is solved, and the production cost is reduced; during maintenance, the assembling and disassembling workload is reduced, and the labor intensity of operators is reduced.

Description

technical field [0001] The invention belongs to the technical field of chemical industry and metallurgy, in particular to an integrated bottom of a chlorination furnace for producing titanium tetrachloride. Background technique [0002] At present, titanium tetrachloride production enterprises at home and abroad adopt the boiling chlorination method to produce titanium tetrachloride. Titanium tetrachloride is used as an important raw material for the production of sponge titanium and titanium dioxide. The production process of titanium tetrachloride uses titanium-rich materials and petroleum coke Chlorination reaction with chlorine gas in a chlorination furnace to obtain titanium tetrachloride, an important intermediate product in the titanium industry. The bottom technology of the chlorination furnace used by most production enterprises at present is a combination of a separable chlorine gas feed pan and the bottom of the furnace. In order to prevent chlorine gas from corr...
