Problems solved by technology

Moreover, electric heating, steam heating, oil heating, etc. are used for heating, and the surface temperature of the heater is relatively high, causing the sol to adhere to the surface of the heater, reducing thermal efficiency, increasing energy consumption and concentration time
Because of the agglomeration of the sol attached to the surface of the heater, the viscosity of the sol product also increases
[0004] In the traditional colloidal antimony pentoxide production method, the liquid-solid ratio of the oxidation reaction is large, and the chemical reaction cannot proceed smoothly at a low liquid-solid ratio (causing the slurry to solidify), and there are defects such as long concentration process time, high energy consumption, and affecting product viscosity.

Abstract

The invention discloses a colloidal antimony pentoxide manufacturing device. The colloidal antimony pentoxide manufacturing device comprises a hydrogen peroxide head tank, a microwave reaction kettle,a filtering device and a packaging barrel which are sequentially connected through pipelines from top to bottom, wherein a connecting port of a deionized water device and a material adding port are arranged above the microwave reaction kettle; a hydrogen peroxide flowmeter is arranged on a pipeline between the hydrogen peroxide head tank and the microwave reaction kettle; and a metering device isarranged below the packaging barrel. The invention further discloses a method for manufacturing colloidal antimony pentoxide by using the colloidal antimony pentoxide manufacturing device. The deviceis simple in structure, a catalyst is introduced during reaction, oxidation reaction and concentration are carried out by adopting microwave heating, the liquid-solid ratio of the oxidation reactionis greatly reduced, and the reaction speed is increased; and particularly when high-concentration colloidal antimony pentoxide is produced due to the reduction of the liquid-solid ratio, water needingto be evaporated during concentration can be greatly reduced, so that the energy consumption is greatly reduced. The process time is shortened, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a production device and method of antimony pentoxide, in particular to a production device and method of colloidal antimony pentoxide. Background technique [0002] Antimony is one of the top ten non-ferrous metals, occupies a very important position in the national economy, and has been widely used in transportation, chemical industry, flame retardant materials and military industry and other departments. [0003] At present, the production process of colloidal antimony pentoxide is: adding antimony trioxide into water to slurry, heating by means of electric heating, steam heating, oil heating, etc., heating to about 60°C and slowly adding hydrogen peroxide for oxidation. The slurry liquid-solid ratio is greater than or equal to 4:1, and the liquid-solid ratio is lower than 4:1, which may cause the slurry to solidify during the reaction and produce waste products. The disadvantages brought about by the large liquid-solid rati...
