Description

Technical Field

[0001] The utility model relates to the technical field of high-purity phosphorus product preparation, in particular to a product collection device for preparing high-purity phosphorus through bromine reduction. Background Art

[0002] High-purity phosphorus is mainly used to prepare III-V compound semiconductors, high-purity alloys, and germanium and silicon single crystal dopants. With the development of related material industries represented by semiconductor materials, especially the development of gallium phosphide and indium phosphide industries, the demand for high-purity phosphorus has gradually increased. In the process of preparing high-purity phosphorus by bromine reduction, corresponding product collection devices are often used.

[0003] The existing product collection device for preparing high-purity phosphorus by bromine reduction generally introduces the liquid phosphorus obtained by reduction into pure water safely to become solid yellow phosphorus and avoid spontaneous combustion. The yellow phosphorus and pure water can be safely transferred to a receiving bottle together through the bottom valve control for easy delivery to the subsequent production process, wherein a trace amount of yellow phosphorus gas is absorbed by the alkali liquid spray absorption tower along with the hydrogen chloride gas and the tail gas is cooled to room temperature before being discharged, ensuring continuous, safe and smooth production without causing pollution to the environment. Although the existing technology can complete the reduction and discharge collection of high-purity phosphorus, the existing technology directly puts pure water and bromine and other reactants into the reaction barrel for autonomous reaction, resulting in incomplete contact of the reactants, resulting in insufficient reaction. After the high-purity phosphorus is generated, the liquid outlet pipe is only opened by the bottom valve for discharge and collection. Part of the high-purity phosphorus will adhere to the inner wall of the liquid outlet pipe, causing the collection operation to be difficult to carry out normally. Therefore, we urgently need to improve a product collection device for preparing high-purity phosphorus by bromine reduction to solve the above problems. Utility Model Content
