Recovery device for crude titanium tetrachloride

Abstract

The utility model discloses a recovery device for crude titanium tetrachloride. The device mainly comprises a titanium tetrachloride storage tank, a titanium tetrachloride intermediate tank, a pump, ahorizontal centrifuge and a solid collection tank, wherein the titanium tetrachloride storage tank is connected with the titanium tetrachloride intermediate tank through a pipeline, the pump is arranged on the pipeline, the titanium tetrachloride intermediate tank is connected with the horizontal centrifuge through a liquid outlet pipe, a feeding pipe is arranged on the horizontal centrifuge, andthe horizontal centrifuge is connected with the solid collecting tank through a solid outlet pipe. When the chlorination furnace is used for producing crude titanium tetrachloride through chlorination, crude titanium tetrachloride containing solid particles enters a horizontal centrifuge from a feeding pipe, then under the separation effect of a horizontal centrifuge, the titanium tetrachloride liquid enters and exits the titanium tetrachloride intermediate tank from the liquid outlet pipe, so that titanium tetrachloride in the intermediate tank is conveyed into the titanium tetrachloride storage tank through the pump; meanwhile, separated solid particle impurities enter the solid collection tank, the effect of effectively separating titanium tetrachloride from the solid particle impurities is achieved, and crude titanium tetrachloride is recycled.

Description

technical field [0001] The invention belongs to crude titanium tetrachloride production equipment, in particular to a device for separating unreacted petroleum coke particles, high-titanium slag particles and crude titanium tetrachloride during the production of crude titanium tetrachloride. Background technique [0002] At present, the domestic and foreign industrial production of crude titanium tetrachloride adopts the method of fluidized chlorination, that is, boiling chlorination. The solid particles are suspended by the action of the flowing fluid, so that the solid particles have certain fluid performance characteristics, so the gas- In the process of solid or liquid-solid contact, during the chlorination reaction process, a small part of the particles have no time to react, and enter the dust collector with the crude titanium tetrachloride airflow. Due to the combination of factors such as low dust removal efficiency of the dust collector, large chlorine gas flow rate...
