Abstract

The invention belongs to the technical field of activated coke desulfurization and denitrification, and specifically provides a rapid evaluation method for the regeneration effect of desulfurization and denitrification activated coke. Activated coke sample B, then take a certain amount of samples and crush them to obtain broken samples A and broken samples B, and finally add deionized water to stand still, and then measure the pH value of the filtrate respectively, which are respectively recorded as C A and C B ; Evaluate the regeneration effect of active coke according to the formula (1). This scheme can evaluate the regeneration effect of active coke that is being recycled in the desulfurization and denitrification system. The pH value of active coke before and after regeneration is used to characterize the regeneration effect of active coke. The time is shortened from several hours of traditional desulfurization and denitrification performance testing to several minutes, and does not require huge desulfurization and denitrification performance testing equipment, which can realize real-time and rapid evaluation of active coke regeneration effect without affecting normal production operations.

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...
