Titanium tetrachloride spray washer and washing method

Abstract

The invention relates to a production technology of titanium tetrachloride, particularly discloses a spray washer for producing titanium tetrachloride and a washing method, and solves the problems of poor cooling, mixing and aggregation effects, low efficiency caused by uneven mixing, and the like in the prior art. An upper shell, a middle shell and a lower shell of the spray washer are connected into a whole from top to bottom, so as to form an inner cavity; an upper cover is arranged at the top of the upper shell; a feeding pipe and an ejector are arranged on the upper cover; the upper cover is connected with the upper shell; the feeding pipe and the lower part of the ejector extend to the inside of the upper shell; the ejector comprises a steel pipe, an inlet, a connecting rod and a spray plate; the inlet is arranged at the side of the upper part of the steel pipe; an end cover is arranged at the end face of the upper part of the steel pipe; the connecting rod is arranged in a manner of penetrating through the center of the end cover; and the spray plate is arranged at the lower part of the connecting rod. By adopting the titanium tetrachloride spray washer, a gas mixture is fully and evenly cooled, mixed and agglutinated into liquid; a quick-wear part spray plate of the ejector is easy to replace, and not easy to block; the titanium tetrachloride spray washer is simple in structure, long in service life, low in cost and durable.

Description

technical field [0001] The invention relates to the production technology of titanium tetrachloride, in particular to a spray scrubber and a washing method for producing titanium tetrachloride. Background technique [0002] In the production of titanium tetrachloride, TiCl from the dust chamber 4 , CO 2 , C, TiO 2 , SiO, iron, aluminum, magnesium, sodium and other metal chlorides, these high-temperature gas mixtures need to be sprayed to cool down, mixed, condensed into liquid, and flow into the circulation pump tank for the next process. Production. The existing technology is to install a spray device inside the scrubber, and the top-down spray contacts with the furnace gas rising from the bottom in reverse to make it cool down, mix and condense into liquid. This structure makes the effect of cooling, mixing and agglomeration poor, and the mixing is uneven. However, the nozzles of the spraying device are easily blocked when they are directly in contact with the suspend...

AI Technical Summary

Problems solved by technology

This structure makes the effect of cooling, mixing and agglomeration poor, and the mixing is uneven

However, the nozzle of the spray device is easily blocked when it is in direct contact with the suspended matter, and the spray cannot produce retroreflection, which also makes it inefficient
