TiCl4 (titanium tetrachloride) drop catcher

Abstract

The invention relates to the field of TiCl4 (titanium tetrachloride) production equipment and particularly relates to a drop catcher for producing TiCl4. The TiCl4 drop catcher is provided with a cover plate, an upper shell, a lower shell, a partition plate, a gas inlet, a gas outlet, a liquid inlet and a liquid outlet, wherein the upper and lower shells are sequentially arranged on the lower part of the cover plate, and are communicated with each other; the cover plate, the upper shell and the lower shell form an inner cavity of the drop catcher; the partition plate is arranged in the upper shell; the inner cavity of the drop catcher is partitioned into a left chamber and a right chamber by the partition plate; the gas inlet and the liquid inlet are formed in the cover plate, and are communicated with the left chamber; the gas outlet communicated with the right chamber is formed in the cover plate; the axes of the gas inlet and the gas outlet are parallel to that of the drop catcher; the liquid outlet is formed in the lower part of the lower shell. According to the drop catcher, the multi-stage connection of a process is facilitated, pressure loss is reduced, a good drop catching effect is achieved, the influence of environmental temperature changes on the drop catching effect is reduced, the using amount of low-temperature TiCl4 liquor is reduced, equipment can be conveniently inspected and maintained, and the service life of the equipment is prolonged.

Description

technical field [0001] The invention relates to the field of titanium tetrachloride production equipment, in particular to a drop catcher for producing titanium tetrachloride. Background technique [0002] In the production of titanium tetrachloride, the furnace gas that has undergone preliminary dust removal contains a lot of CO and CO 2 , Cl 2 , HCl and other mixed gases, the trapping method is often used to make the valuable component TiCl 4 Gases are separated from them. The freezing point of most gas impurities is very low, only TiCl 4 higher. The method of using droplet capture is to make the TiCl in the furnace gas at normal temperature or a temperature slightly lower than normal temperature. 4 The gas condenses into a liquid, while other gases escape from the tail gas to reach the droplet of TiCl 4 liquid purpose. In the existing drop catcher technologies, some make the axis of the furnace gas inlet not parallel to the axis of the drop catcher, so that the upp...

AI Technical Summary

Problems solved by technology

In the existing drip catcher technology, some of the axis of the furnace gas inlet are not parallel to the axis of the drop catcher, so that the upper cover plate and the isolation plate are washed by corrosive gas for a long time and the service life is reduced. Due to the existence of multiple corners, the The pressure loss is large, and it is not conducive to the multi-stage connection of the process; there is no insulation facility, and when the ambient temperature rises, it is necessary to increase the low-temperature TiCl 4 The amount of liquid; there is no upper detection port and lower cleaning port, which brings inconvenience to production and maintenance
