Abstract: Disclosed is a phosphorus coal gasification reaction device for combined production of yellow phosphorus and syngas, including a stock bin, a mineral aggregate lock hopper, a phosphorous coal gasification reactor, a slag quench chamber and a slag lock hopper. In the phosphorous coal gasification reactor, a drying zone, a dry distillation zone, a combustion zone, a phosphate rock reduction zone, and a slag bath zone are formed from top to bottom. A gas product outlet communicating with the phosphorous coal gasification reactor is installed at a top of the phosphorous coal gasification reactor, two to eight fuel burners are symmetrically arranged on the combustion zone, and an auxiliary burner communicating with the slag bath zone is arranged at the bottom of the slag bath zone. The reactor device can improve the production capacity of the yellow phosphorus, and reduce the emission of CO2.

Abstract: A system for combined production of yellow phosphorous and syngas is disclosed. The air separation unit, the pulverized coal preparation unit and the mineral aggregate forming unit are respectively connected to a gas inlet and a top feeding port of the phosphorus coal gasifier; phosphorus-containing syngas obtained from phosphorus coal gasifier is connected to a gas inlet of the separating washing unit through an outlet of the phosphorous coal gasifier; Yellow phosphorus products and crude syngas are respectively output from the output port of the separating washing unit; and then the crude syngas is purified to obtain refined syngas. A slag discharge port at the bottom of the phosphorus coal gasifier is connected to an input port of a slag cold quenching unit. The system can improve the available energy of yellow phosphorous production, the production capacity of yellow phosphorus and the yield of syngas, and reduce CO2 emission.
