Embodiment Construction

[0008] As shown in the figure, the present invention includes a pot-shaped housing 1, the outer edge of the upper end of the housing 1 is provided with a connecting flange 5 for connecting with the chlorination furnace, and a reinforcement is provided between the connecting flange 5 and the housing 1. Rib 6. The lower end of the casing 1 is provided with a slag discharge pipe 4 . A number of chlorine gas straight-through pipes 3 and chlorine gas oblique pipes 2 are provided along the side of the housing 1, wherein the chlorine gas straight-through pipes 3 are arranged horizontally; -45° angle. The total number of chlorine gas straight-through pipes 3 and chlorine gas inclined pipes 2 is 8-16, and each accounts for half. Chlorine gas straight-through pipe 3 and chlorine gas inclined pipe 2 pipe diameters are 1 cun-57mm, and the length inserted into the bottom of the furnace is 400-500mm.

Abstract

The invention discloses a novel furnace bottom distributor of a sieve-plate-free fluidizing chlorination furnace, which comprises a basin-shaped casing. A plurality of horizontal chlorine direct connection pipes and upward sloping chlorine oblique connection pipes are arranged along the lateral face of the casing, and the horizontal chlorine direct connection pipes and the upward sloping chlorineoblique connection pipes are distributed alternately. Due to the fact that the horizontal chlorine direct connection pipes and the upward sloping chlorine oblique connection pipes are distributed alternately, the chlorine oblique connection pipes also form a protective screen for the chlorine direct connection pipes while forming a self eddy protective screen, and thick calcium magnesium impurities and furnace clinkers are not apt to block the connection pipes. Simultaneously, airflow distribution can be even, the impurities are prevented from entering the connection pipes, so that certain fluidization speed is retained, furnace temperature is led to be stable, fluidization bed height is reasonable, stability and stability of production are improved, operation is easy and simple, chlorineunit consumption is reduced to 0.98t / t, sorting range of rich titanium material is improved, maximum content of the calcium magnesium impurities of the rich titanium material is improved to 4.5%-5%.

Description

1. Technical field [0001] The invention belongs to the technical field of titanium smelting, and in particular relates to a novel bottom chlorine gas distributor of a boiling chlorination furnace without a sieve plate. 2. Background technology [0002] The chlorine gas distributor currently used in the bottom of a sieveless fluidized chlorination furnace is usually composed of a basin-shaped shell and chlorine gas straight-through pipes distributed along the side of the shell. Chlorine gas enters the furnace through these through pipes for distribution. Since the straight-through pipes of chlorine gas of this kind of distributor are horizontally inserted into the bottom of the furnace, it is difficult for the straight-through pipes of chlorine gas to blow against each other to form an airflow barrier. In this way, when there are many impurities or when the chlorine is stopped and the slag is discharged, the viscous calcium and magnesium impurities can easily enter the pipe a...
