Method and system for quickly evaluating performance state of desulfurization and denitrification active coke

Abstract

The invention relates to a method for quickly evaluating the performance state of desulfurization and denitrification active coke. The method comprises the following steps of: 1, after an active cokedesulfurization and denitrification system normally operates for a period of time, taking one part of active coke in each stage, and dividing the taken active coke in each stage into two parts; and 2,volatilizing the two parts of active coke in each stage at different temperatures, recording the weight of the volatilized active coke, calculating the volatile component of the active coke in each stage based on the weight of the volatilized active coke, and judging the performance state of the active coke in each stage through the volatile component of the active coke in each stage. According to the method, based on volatilization of the active coke at each key point of the active coke desulfurization and denitrification system, the performance state of the active coke at each point can berapidly evaluated through a set of calculation formula and evaluation system, and possible faults of the system are 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 quickly evaluating the performance state of desulfurization and denitrification active coke. Background technique [0002] Activated coke desulfurization and denitrification technology is a dry flue method that uses the adsorption and catalytic functions of active coke to remove SO2, NOx, particulate matter, mercury, dioxins, furans, heavy metals, volatile organic compounds and other pollutants in the 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 recovered as resources. 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. In the process of desulfu...

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
