AI Technical Summary

Technical Problem

The high-temperature and high-humidity gases generated during the crystallization of boron anhydride are difficult to purify completely. Traditional equipment occupies a large area and the performance of the adsorbent is prone to decline, resulting in gas emissions that fail to meet standards and pollute the environment.

Method used

A multi-stage purification system is employed, including gas cooling equipment, cyclone dust collectors, dynamic adsorption equipment, electrostatic dust collectors, and chemical spray neutralization towers. Through heat exchange, centrifugal force, electrostatic adsorption, and chemical neutralization, the gas is purified step by step. The dynamic adsorbent is not fixed in position to maintain its performance.

Benefits of technology

It effectively removes impurities and harmful components from gases, reduces factory footprint, ensures gas emissions meet standards, protects the environment, and improves purification efficiency and equipment stability.
