AI Technical Summary

Technical Problem

Existing blast furnace gas purification systems face issues of large occupied area, low operation rate, and complexity in operation, particularly when dealing with large gas generation amounts, with current modular designs being ineffective in reducing scale and pressure loss.

Method used

The system is divided into modular hydrolysis and adsorption units, stacked vertically to form module groups, connected in parallel to gas pipelines, using a radial flow reactor configuration and carbon steel with insulation, and equipped with independent valves for each module.

Benefits of technology

This design improves space utilization, reduces construction costs, enhances operational flexibility and efficiency, and ensures system stability by isolating faulty modules, while minimizing environmental impact and improving gas purification efficiency.

Abstract

Providing a method for arranging a compact, modular blast furnace gas purification system. [Solution] This method includes the steps of: dividing a blast furnace gas purification system into a modular hydrolysis unit 1 and a modular adsorption unit 6 based on a blast furnace gas purification process; stacking multiple modular hydrolysis units 1 and multiple modular adsorption units 6 vertically to obtain multiple module groups; and connecting the multiple module groups in parallel to a gas pipeline to obtain a modular blast furnace gas purification system. The blast furnace gas purification system designed according to the present invention is flexible in operation, occupies a small area, has good spatial adaptability, has a high operating rate, has high gas purification efficiency, and is applicable to the upgrade modification of existing blast furnace purification systems.
