QUENCHING SYSTEM USING DUAL SEPARATION UNIT FOR GAS/SOLID FLUID IN AN ENTRAINED-FLOW GASIFIER

摘要

The present invention relates to a dual structure gas / solid quench separation system of a gasifier, the object of which is to recover the unreacted material and to remove contaminants, and to scale the cooling water outlet and the water level control system by the unreacted and contaminants. It is to provide a gas / solid quench separation system that can prevent occurrence.;In the gasification apparatus, the gas induction pipe 18 of the upper and lower openings provided in the lower part of the slag tab 3 so as to induce the primary pressure of the generated gas produced in the gasification reactor in the gasifier, and this gas induction Auxiliary gas induction pipe 21 having an upper and lower open structure surrounding the circumference of the pipe 18, one side of the cooling tank and a through-gas discharge port 16 penetrated, a cooling water supply line 19 for supplying cooling water to the cooling tank, In addition, the dual-structure gas / solid quench separation system is composed of a water level control system 20 penetrated up and down from the outside of the cooling tank and a cooling water outlet 17 through which one side penetrates to adjust the cooling water level in the cooling tank. The lower portion of the gas induction pipe 21 is formed to be spaced apart from the cooling water discharge port 17 and installed below the cooling water discharge port 17.;Heavy residue oil, coal, gasification, syngas, quenching system, lower hydrocarbon
