Product collecting system for preparing high-purity phosphorus through hydrogen reduction

A product collection system for preparing high-purity phosphorus through hydrogen reduction comprises a primary product collection device (1) and a secondary product collection device (15) which are connected through a pipeline (12), an alkali liquor spraying absorption tower (27) connected with the secondary product collection device through a pipeline, and a tail gas emission chimney (32) connected with the alkali liquor spraying absorption tower through a pipeline. According to the device, liquid yellow phosphorus obtained by hydrogen reduction can be safely introduced into pure water to become solid yellow phosphorus, spontaneous combustion is avoided, and yellow phosphorus and pure water can be safely transferred into a receiving bottle together through control of the bottom valve. The trace yellow phosphorus gas is absorbed by the alkali liquor spraying absorption tower along with the hydrogen chloride gas, and the tail gas is discharged after being cooled to the normal temperature, so that continuous,
