A rapid evaluation method and system for the performance state of desulfurization and denitration activated coke

Abstract

A method for quickly evaluating the performance state of desulfurization and denitrification activated coke, the method comprises: step 1, after the activated coke desulfurization and denitrification system has been operating normally for a period of time, take one copy of each stage of the activated coke, and take one copy of each stage of the removed activated coke The active coke is divided into two parts; step 2, the two parts of the active coke in each stage are volatilized at different temperatures, and the weight of the volatilized active coke is recorded. Based on the volatilized active coke weight, calculate the active coke in each stage. The volatile matter of the coke is judged by the volatile matter of the activated coke at each stage to determine the performance state of the activated coke at each stage. The invention is based on the volatilization of active coke at each key point of the active coke desulfurization and denitrification system, and through a set of calculation formulas and an evaluation system, the performance state of the active coke at each point can be quickly evaluated, and the possible faults of the system can be further judged.

Description

technical field [0001] The invention relates to the field of active coke desulfurization and denitrification, in particular to a method and system for rapid evaluation of the performance state of desulfurization and denitrification activated coke. Background technique [0002] Activated coke desulfurization and denitrification technology is a dry-process flue gas that utilizes the adsorption and catalytic functions of activated coke to integrally remove SO2, NOx, particulate matter, mercury, dioxin, furan, heavy metals, volatile organic compounds and other multi-pollutants in flue gas. gas treatment technology. Activated coke desulfurization and denitrification technology has good pollutant removal effect, low energy consumption, no white smoke, and by-products can be recycled. It is a flue gas purification technology with great development potential. [0003] Activated coke for desulfurization and denitrification is a porous carbonaceous material made of coal. The group c...

Problems solved by technology

[0005] At present, the basic idea of ​​the active coke performance testing system is to simulate the flue gas and temperature conditions of active coke desulfurization and denitrification in the laboratory, quantitatively control the inlet flue gas conditions, and measure the adsorption capacity of active coke to describe the adsorption performance of active coke For example, the Chinese patent application CN201120299729.5 generates simulated test flue gas through a coal-fired water heater, and the Chinese patent application CN201410247416.3 simulates the composition of the flue gas through the gas distribution system. This method is used to test and evaluate the performance of active coke. It takes several hours, which is far from meeting the requirements for rapid detection and evaluation of active coke at multiple points in the operation site
