Rapid evaluation method for regeneration effect of desulfurization and denitrification active coke

Abstract

The invention belongs to the technical field of activated coke desulfurization and denitrification. Specifically, the invention provides the rapid evaluation method for the regeneration effect of thedesulfurization and denitrification active coke. The method comprises the following steps: respectively taking one part of an active coke sample A and one part of an active coke sample B at an inlet and an outlet of an active coke regeneration tower, respectively taking a certain amount of samples, crushing to obtain a crushed sample A and a crushed sample B, finally adding deionized water, standing, respectively measuring the pH values of filtrate, and respectively marking as CA and CB; and evaluating the regeneration effect of the active coke according to the formula (1). According to the scheme, the regeneration effect of the active coke recycled in the desulfurization and denitrification system can be evaluated; the pH values of the activated coke before and after regeneration are usedfor representing the regeneration effect of the activated coke, the evaluation time can be shortened to several minutes from several hours of a traditional desulfurization and denitrification performance test, huge desulfurization and denitrification performance test equipment is not needed, the regeneration effect of the activated coke can be rapidly evaluated in real time, and normal productionoperation is not influenced.

Description

technical field [0001] The invention belongs to the technical field of active coke desulfurization and denitrification, and in particular relates to a rapid evaluation method for the regeneration effect of desulfurization and denitrification active coke. Background technique [0002] Activated coke desulfurization and denitrification technology uses the adsorption and catalytic functions of active coke to remove SO2 and NOx at the same time, and can also simultaneously remove soot particles, mercury, dioxins, furans, heavy metals, volatile organic compounds and other traces in the flue gas. Elements, and dry flue gas treatment technology for sulfur resource recovery. Activated coke desulfurization and denitrification technology has the advantages of less energy and water consumption, basically no secondary pollution, small footprint, and high value of by-products. It has been widely used in many fields such as coal-fired power generation and steel sintering flue gas treatmen...
