Abstract

The invention provides a device for acidolysis reaction in a sulfuric acid method titanium dioxide process, which comprises a reaction kettle, a heating device is arranged at the bottom of the reaction kettle, a discharge port is arranged at the bottom of the reaction kettle, a feeding port is arranged on one side of the top of the reaction kettle, and a mounting hole is arranged in the center ofthe top of the reaction kettle. A mounting cover is connected to the mounting hole through a flange, a rotating shaft is rotatably arranged on the mounting cover, a driving device is connected to thetop of the rotating shaft, an expansion head is arranged at the bottom of the rotating shaft, and a plurality of soft chains are connected to the rotating shaft above the expansion head. The inventionmainly relates to the field of reaction containers. The defoaming device has the beneficial effects that foam generated by reaction can be effectively defoamed, so that the phenomenon of tank overflow is avoided, the normal operation of the reaction is guaranteed, and the personal safety of workers during operation is protected.

Description

technical field [0001] The invention mainly relates to the field of reaction vessels, in particular to a device for acidolysis reaction in sulfuric acid titanium dioxide process. Background technique [0002] Titanium dioxide production mainly includes sulfuric acid method and chlorination method. The sulfuric acid method has a history of more than 80 years, and the production process is mature. Compared with the chlorination method, the equipment and operation are simple, the production cost is low, the investment in plant construction is small, and the raw materials are cheap. It is widely used in the titanium dioxide industry. [0003] When the sulfuric acid method is used to prepare titanium dioxide, the added powdery ilmenite is acidolyzed mainly by using the sulfuric acid dilution heat and the certain high temperature and pressure conditions generated by the reaction heat. During the reaction process, due to the agitation of the stirring device in the reaction tank an...
