pH Value Adjusting of the Recycled Spraying Cleaning Solution for Wet Dust Precipitation and Desulfurization Device

Sun Shen

Abstract

The purification mechanism,the preparation and the pH value control of several kinds of desulfurization agents used in wet desulfurization are introduced in the paper.Such a type of desulfurization agent as NaOH- Ca(OH) 2 has been used in the RD of high efficient desulfurization and dust precipitation device.The results of the practical operation have significant importance for the the pH value control of absorption solution.
