Abstract

The invention provides a yellow phosphorus antimony removing device. The yellow phosphorus antimony removing device comprises an antimony removing groove, liquid level devices, circulating pumps and a discharging pump, wherein a jacket is arranged on the outer part of the antimony removing groove and a water inlet pipe is arranged below one end of the jacket; a water outlet pipe is arranged above an opposite end of the water inlet pipe of the jacket; a cover plate is arranged above the antimony removing groove; a discharging opening is formed below the water outlet pipe of the jacket; the discharging opening is connected with the discharging pump; the antimony removing groove is separated by a separation plate and is provided with one antimony removing chamber and more than two waster washing chambers; each chamber is provided with the independent liquid level device, the independent circulating pump and a spraying device; the circulating pumps comprise a reaction circulating pump and a water washing circulating pump. With the adoption of the yellow phosphorus antimony removing device, an oxidized antimony removing agent is sprayed to smelted-state yellow phosphorus at a high pressure and the contact area between the yellow phosphorus and the antimony removing agent is enlarged so that the yellow phosphorus and the antimony removing agent are sufficiently mixed; the yellow phosphorus enters a liquid phase under the effect of the antimony removing agent so as to realize the removing aim, efficiently remove antimony and guarantee the recycling rate of the phosphorus.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment, and in particular relates to a yellow phosphorus deantimony device. Background technique [0002] Yellow phosphorus is a very important basic chemical raw material, which is widely used in the production of food additives, medicines, microelectronic integrated circuit etching cleaning agents, and semiconductor diffusion additives. As some important phosphides, especially some high-quality phosphorus chemicals, are continuously expanded and the variety is gradually increasing, the market demand for yellow phosphorus products is getting higher and higher. The main impurities of yellow phosphorus are arsenic, iron, antimony, silicon, manganese, organic matter, solid particles, etc. Among them, arsenic, antimony and organic matter are the focus and difficulty of yellow phosphorus purification. A lot of research has been done on the purification of yellow phosphorus at home and abroad, and...
