Abstract

The invention relates to a device and technique for purifying and processing titanium white waste acid. The device comprises a separating pot, a sealing cover, a filter core, a connector, a porous plate, supporting rings, an inclined plate and an inclined plate partition plate, wherein the separating pot and the sealing cover are fixed by a sealing ring; the sealing cover is provided with a clear solution outlet; the separating pot is of a structure with shaped cylindrical upper part and a conical lower part; the bottom of the cone is provided with a solution outlet; a material solution inlet is arranged below the cylinder; the three supporting rings are arranged from top to bottom in the separating pot; the porous plate provided with the inclined plate is arranged on the lower supporting ring; the middle supporting ring is arranged on the inclined plate and provided with the porous plate which is provided with the filter core; the upper part of the filter core is arranged on the upper supporting ring; and the water outlet of the filter core is connected with the clear solution outlet by the connector. A material solution is configured to form a rotational flow after entering the separating pot, a part of particles sink directly, the liquid flows upwards by the porous plate, a large amount of particles are settled by the inclined plate firstly, the particle impurities are removed by the filter core, the clear waste acid solution is obtained by the collection at the clear solution outlet, and the accumulated particles and powder are discharged by a solution discharge opening.

Description

technical field [0001] The invention relates to a purification device and process for waste acid solution containing powder, in particular to a purification treatment device and process for titanium white waste acid. Background technique [0002] my country is a big country in the production and consumption of titanium dioxide. At present, most enterprises in our country mainly use sulfuric acid production technology. This method produces a large amount of dilute sulfuric acid waste acid containing solid titanium dioxide particles in the production process, which is difficult to effectively utilize. The current treatment method is mainly to use distillation to concentrate waste sulfuric acid to a certain concentration and use it to realize turning waste into treasure. Among them, due to the production of titanium dioxide by the sulfuric acid method, especially when producing nano or submicron titanium dioxide products, the discharged waste sulfuric acid still contains a sma...
