Material balance control method, device and system for analysis system

Abstract

The embodiment of the invention discloses a material balance control method, device and system for an analysis system, and the method comprises the steps: obtaining the actual feeding time of each analysis tower and the first working frequency of a round roller unloader of each analysis tower in a preset time period, wherein the analysis system comprises a first analysis tower and a second analysis tower; if the relative deviation value of the actual feeding time of the analysis tower does not meet a preset first deviation threshold value range, generating a second working frequency of the round roller unloader of the analysis tower according to the actual feeding time and a first working frequency of the analysis tower; and adjusting the first working frequency of the round roller unloading machine of the desorption tower into the second working frequency. The actual blanking time of each analysis tower is utilized to adjust the working frequency of the round roller unloader of each analysis tower, so that the blanking amount of each analysis tower is accurately controlled, the blanking amount of each analysis tower tends to be consistent, and the stable operation of the system is ensured.

Description

technical field [0001] The invention relates to the technical field of flue gas purification, in particular to a material balance control method, device and system for an analysis system. Background technique [0002] At present, in iron and steel enterprises, sulfur oxides (such as SO2, etc.) In order to prevent the air pollution caused by gas emissions, the sintering flue gas must be desulfurized and denitrified. Iron and steel enterprises usually adopt a special flue gas purification system, in which materials with adsorption function (such as activated carbon) are placed to absorb the sintering flue gas, so as to realize the desulfurization and denitrification of the sintering flue gas. [0003] see figure 1 , figure 1 What is shown is a schematic structural view of a flue gas purification system in the prior art. to combine figure 1 It can be seen that the flue gas purification system includes: absorption system 1, analysis system 2, analysis tower feeding conveyor...

AI Technical Summary

Problems solved by technology

[0006] The present invention provides a material balance control method, device and system for the analysis system to solve the problem in the prior art that due to the large length of the round roller unloader, the analysis tower is discharged by the round roller unloader, which is difficult to do. To absolutely uniform feeding, the material feeding amount of each analysis tower will deviate from the design value, which will cause problems of incomplete analysis or energy waste
