INSTALLATION FOR THE SYNTHESIS OF THE TITANIUM DIOXIDE AND THE METHOD FOR THE SYNTHESIS OF THE TITANIUM DIOXIDE Russian patent published in 2007 - IPC C01G23/47 C01G23/07 B04C5/08 

FIELD: chemical industry; methods and installations for the synthesis of the titanium dioxide.

SUBSTANCE: the invention may be used for production of the powdery titanium dioxide using the chloride process engineering. The installations for the synthesis of the titanium dioxide contains: the plasmatron (1), to which the source (2) of oxygen or the oxygen-containing gas is connected; the plasma-chemical reactor (3) connected to the consumption tank (4); the device (5) used for feeding of the titanium tetrachloride; the hardening chamber (6); the single-pipe heat exchanger (8) of the "the pipe inside the pipe" type; the synthesis products separation block (10). The synthesis products separations block consists of the cyclone (11) and the screen (13). The hardening chamber has the cylindrical body, the cone bottom of which is connected to the hopper (21) with the coarse fractions of titanium dioxide and to the radially arranged outlet fitting pipe (9). The hardening chamber is additionally supplied with the pneumoimpulsive generator (7). The trunk (14) of the pneumoimpulsive generator is mounted in the lower part of the cylindrical body coaxially and diametrically opposite to the radial outlet fitting pipe (9). The cyclone of the synthesis products separation block, which inlet is connected to the heat exchanger (8,) is made with the axially symmetric leveling chamber (15), which is coaxially arranged between the body and the discharge pipe (17) at the following ratio of the geometrical parameters: d/D = (0.l÷0.7), where "d" is the maximum diameter of the leveling chamber; "D" is the diameter of the cylindrical body. The method of the synthesis of the titanium dioxide provides that refrigerating of the reaction products after the hardening chamber is exercised at the flow of the dust-gas stream in the single-pipe heat exchanger of the " a pipe inside the pipe" type with the mass speed - the mass stream density from 5 up to 80 kg/ms. The invention allows to boost efficiency and reliability of the installation operation for the synthesis of the titanium dioxide.

EFFECT: the invention allows to increase efficiency and reliability of the installation operation for the synthesis of the titanium dioxide.
