Abstract

The invention provides a gasification reduction device for co-production of yellow phosphorus and synthesis gas. The gasification reduction device comprises a phosphocoal gasification reduction unit and a chilling unit. The phosphocoal gasification reduction unit is communicated with the chilling unit vertically, and the phosphocoal gasification reduction unit is used for realizing gasification reduction reaction of all materials in the phosphocoal gasification reduction unit to obtain phosphorus-containing furnace gas; and the chilling unit is used for cooling slag formed in the phosphocoal gasification reduction reaction process into a solid state and discharging the solid state. The invention also provides a method for implementing co-production of yellow phosphorus and synthesis gas byusing the gasification reduction device. The gasification reduction device is a technology which is high in energy utilization rate, optimized in process, energy-saving, environment-friendly and lower in cost.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a gasification reduction device and method for co-producing yellow phosphorus and synthesis gas. Background technique [0002] Yellow phosphorus is one of the important basic chemical raw materials. It is an important parent material for the production of thermal phosphoric acid and phosphides, and it is also an important raw material for the preparation of fine phosphate and fine organic phosphorus chemicals. At present, there are only two methods for industrialized yellow phosphorus production: blast furnace phosphorus production and electric furnace phosphorus production. [0003] The technological process of blast furnace phosphorus production is to use massive phosphate rock as raw material, silica as flux, coke and anthracite as reducing agent and fuel, which are added to the blast furnace in a certain proportion and order. In the furnace, the coke is burned with the help ...
