Solid-liquid-gas separation system for improving WGSR gas composition after coal gasification

Abstract

The invention relates to a solid-liquid-gas separation system for improving WGSR gas composition after coal gasification. The solid-liquid-gas separation system is composed of a gas-solid separation system and a gas-liquid separation system. According to the invention, coal gasification products are convenient to put and high-quality combustible gas fuel is convenient to output, the products after coal gasification can be fully filtered and separated, tiny solid products are separated from the gasification products through a gas-solid separation system, the gas fuel after one-step separation is clean, and solid impurities are thoroughly filtered. External motor bearing equipment can control the running speed of the system, and the running progress can be effectively mastered; the gas-solid separation system can effectively screen out part of solid particles mixed in coal gasified fuel, so that the cleanliness of the fuel is guaranteed; and the two-step gas-liquid separation system can better purify CO required in the water gas shift reaction (WGSR) and ensure safe and effective reaction, so that the purposes of efficiently protecting the environment, improving the reaction effect and ensuring the safety and the effectiveness of the industrial process of preparing hydrogen by the WGSR are achieved, and valuable reference can be provided for the industrial process.

Description

technical field [0001] The invention belongs to the technical field of slag removal and filtration, and in particular relates to a solid-liquid-gas separation system for improving WGSR gas composition after coal gasification. Background technique [0002] Coal gasification is a reaction process in which coal, coke, semi-coke and other fuels (solid form) are reacted under certain conditions to produce gas with a small amount of solid residue. When hydrogen is produced by water-gas shift reaction (WGSR), CO 、H 2 It mainly reacts with synthesis gas, and after subsequent processes such as conversion, hydrogen purification, and methanol low-temperature washing process, high-purity product hydrogen is obtained. After the basic processes of slagging and washing, the gas products still contain A small amount of solid particle impurities, which to a certain extent reduces the safety efficiency of subsequent fuel combustion and utilization; in the coal gasification products mainly us...

AI Technical Summary

Problems solved by technology

However, there are certain solid residues in the fuel after coal gasification, and there are hazards such as explosions in the subsequent combustion. Due to the existence of these impurities, many problems are brought to the combustion, such as low processing capacity, low combustion efficiency, and high combustion efficiency. The process safety factor is not high, etc.
