Abstract

The invention belongs to the field of titanium dioxide production equipment, and particularly relates to a crushing aid adding system in chlorination process titanium dioxide production, which comprises an aid tank for storing aids, a discharge port of the aid tank is connected with a feed port of a steam powder machine through an aid pipeline, and the aid pipeline is connected with a superheated steam pipeline. According to the invention, superheated steam is introduced into the auxiliary agent pipeline, so that after the steam enters the auxiliary agent pipeline, the organic auxiliary agent is instantly vaporized and enters the steam powder machine together with the steam; therefore, the organic auxiliary agent enters the system in a stable gas phase, the adding uniformity and stability of the organic auxiliary agent can be well ensured, the problem of non-uniform coating of titanium dioxide organic matters is solved, and the product quality is ensured.

Description

technical field [0001] The invention belongs to the field of titanium dioxide production equipment, and in particular relates to a crushing aid addition system in the production of titanium dioxide by a chloride method. Background technique [0002] The post-treatment process in the production process of chloride titanium dioxide involves the steam powder process; in the steam powder process, the dried titanium dioxide is blown into the steam mill for steam grinding, and during the steam grinding, the flash dryer The bulk material formed inside will be pulverized and organically treated; the function of organic treatment is to improve the wetting, dispersing and rheological properties of titanium dioxide in various dispersion media, which can reduce the absorption of water during storage and make the pigment in the Agglomerates are reduced, and the gloss and dispersibility of titanium dioxide are improved. The existing steam powder adding process is to add additives directly...
