摘要

在喷淋吸收装置中对电石渣浆液吸收SO2进行了系统研究。研究结果表明：脱硫效率随烟气SO2浓度的增加先升高，然后下降；随体系pH的增加而升高，pH从3升到13时，脱硫效率由52.3%升到94.7%；增加浆液电石渣浓度和减小电石渣粒径均有利于SO2的吸收去除；液气比从10 L·m-3增加到50 L·m-3时，脱硫效率提高了59.9%；以电石渣烟气脱硫的化学反应为基础，建立电石渣烟气脱硫反应动力学模型，总反应级数n=α+β=1.67，反应活化能Ea=51396.59 J·mol-1，频率因子k0=0.37894×106(mol·m-3)-0.67·s-1。

Abstract

Absorption process of SO2 by carbide slag slurry in spray tower was studied in this work.The results show that with increase of SO2 concentration in flue gas its removal rate is a volcano curve.When pH value changes from 3 to 13，the removal rate of SO2 goes up from 52.3% to 94.7%.Increasing concentration of carbide slag slurry and decreasing their grain diameter can improve absorption of SO2. When L/G increases from 10 L·m-3 to 50 L·m-3，the removal efficiency puts up by 59.9%，but drops by 14.3% while L/G was continually raised from 50 L·m-3 to 80 L·m-3.A mathematics model is built based on the chemical reaction of desulfurization by carbide slag，the overall reaction order n=α+β=1.67，the activation energy Ea=51396.59 J·mol-1 and the frequency factor k0=0.37894×106 (mol·m-3)-0.67·s-1.
