Titanium liquid continuous crystallization device

Abstract

The utility model relates to the technical field of titanium dioxide processing, in particular to a titanium liquid continuous crystallization device which comprises a titanium liquid input pipe and at least two crystallization chambers connected in sequence, the bottoms of the adjacent crystallization chambers are communicated with each other, a spray tower is arranged on the first crystallization chamber, and the titanium liquid input pipe is connected to the top of the spray tower and extends into the spray tower. The lower end of the crystallization chamber at the tail end is provided with a discharge pipe, the discharge pipe is connected to a crystallized titanium liquid tank, the top of the spray tower on the first crystallization chamber is provided with a vacuum pipe, the tops of the other crystallization chambers are provided with vacuum pipes, the vacuum pipes are connected to a vacuum device, and the vacuum degree is sequentially increased from the first crystallization chamber to the crystallization chamber at the tail end. According to the utility model, a plurality of crystallization chambers are connected in series, and the vacuum degrees of the crystallization chambers are gradually increased, so that titanium liquid can be continuously crystallized when passing through each crystallization chamber, the crystallization stability and uniformity are good, meanwhile, chilled water is continuously used, and the energy consumption is greatly reduced.
