Embodiment 1

[0011] ①Use zirconium oxychloride as the raw material of the strong salt of zirconium, ammonium sulfate as the raw material of alkali metal sulfate, and ammonium bicarbonate as the raw material of alkali. ② Mix zirconium oxychloride, ammonium sulfate and ammonium bicarbonate in a molar ratio of 1:0.5:1. ③Completely mix and grind zirconium oxychloride, ammonium sulfate and ammonium bicarbonate to make them fully react. ④ Mix the reactants with pure water in a ratio of 2:1. ⑤ Separating the mixed slurry from solid to liquid. ⑥Precisely filter the separated liquid to remove suspended impurities, then concentrate and crystallize to produce by-product ammonium chloride. ⑦The solid part continues to be washed with water in the above-mentioned manner, and the lotion is applied mechanically until the chloride meets the product standard requirements (about 5 times), and the solid is basic zirconium sulfate.

Embodiment 2

[0013] ①Use zirconium oxychloride as the raw material of strong acid salt of zirconium, sodium sulfate as the raw material of alkali metal sulfate, and sodium carbonate as the raw material of alkali. ② Mix zirconium oxychloride, sodium sulfate and sodium carbonate in a molar ratio of 1:0.5:0.5. ③Completely mix and grind zirconium oxychloride, sodium sulfate and sodium carbonate to make them fully react. ④ Mix the reactants with pure water in a ratio of 1:1 by weight. ⑤ Separating the mixed slurry from solid to liquid. ⑥Precisely filter the separated liquid to remove suspended impurities, then concentrate and crystallize to produce by-product sodium chloride. ⑦The solid part continues to be washed with water in the above-mentioned manner, and the lotion is applied mechanically until the chloride meets the product standard requirements (about 5 times), and the solid is basic zirconium sulfate.

Embodiment 3

[0015] ① Zirconium sulfate is used as the raw material of strong salt of zirconium, and sodium hydroxide is used as the raw material of alkali. ② Mix zirconium sulfate and sodium hydroxide in a molar ratio of 1:3. ③ Fully mix and grind zirconium sulfate and sodium hydroxide to make them fully react. ④ Mix the reactants with pure water in a ratio of 2:1 by weight. ⑤ Separating the mixed slurry from solid to liquid. ⑥Precisely filter the separated liquid to remove suspended impurities, then concentrate and crystallize to produce sodium sulfate as a by-product. ⑦The solid part continues to be washed with water according to the above method, and the lotion is applied mechanically until the sulfide meets the product standard requirements (about 5 times), and the solid is basic zirconium sulfate.

Abstract

The invention provides a direct production process of basic zirconium sulphate from the strong acid salt of zirconium, sulphates, alkali of base or alkaline-earth metal (including ammonium), which comprises, mixing zirconium strong acid salt solid material or sulphate, alkali of base or alkaline-earth metal (including ammonium) by a finite proportion directly, stirring, grinding to result in complete reaction, washing and dewatering to produce the alkali zirconium sulfate.

Description

technical field [0001] The invention provides a production process for directly producing basic zirconium sulfate by using zirconium strong salt solid material, alkali or alkaline earth metal (including ammonium) sulfate, and alkali as raw materials, and belongs to the technical field of inorganic chemical industry. Background technique [0002] The traditional production process of basic zirconium sulfate usually uses zirconium oxychloride as raw material to make a solution with a certain concentration, then adds a certain amount of sulfuric acid or sulfate, controls the temperature and hydrolyzes to produce basic zirconium sulfate, washes with water, centrifuges Dehydration to obtain the finished product. The technological process is relatively complicated, the energy consumption is large, the water consumption is large, and a large amount of waste water is generated which is difficult to treat and directly discharged to pollute the environm...
