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

Embodiment Construction

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0049] It can be known from the background technology that in the prior art, a round roller unloader is used to control the amount of material in the analysis tower. However, due to the large length of the round roller unloader, the analysis tower is discharged by the round roller It is difficult to achieve absolutely uniform feeding, which will cause the material feeding amount of the analytical tower to deviate from the design value. If the a...

Abstract

The embodiment of the present application discloses a material balance control method, device and system for the analysis system, including: obtaining the actual feeding time of each analysis tower and the time of the round roller unloader of each analysis tower within the preset time period The first operating frequency, wherein the analysis system includes a first analysis tower and a second analysis tower; if the relative deviation value of the actual feed time of the analysis tower does not meet the preset first deviation threshold range, then According to the actual feed time and the first operating frequency of the analysis tower, generate the second operating frequency of the roller unloader of the analysis tower; the first operating frequency of the roller unloader of the analysis tower is adjusted is the second operating frequency. Utilize the actual feeding time of each analysis tower, adjust the working frequency of the round roller unloader of each analysis tower, realize the precise control of the discharge amount of each analysis tower, make the discharge amount of each analysis tower tend to be consistent, and ensure the system Stable operation.

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 analytical system. Background technique [0002] At present, in iron and steel enterprises, sulfur oxides (such as SO2, etc.) and nitrogen oxides (such as NO and NO2, etc.) in the sintering flue gas generated by the sintering process account for the vast majority of the total pollution emissions of iron and steel enterprises. The air pollution caused by gas emission must be treated with desulfurization and denitration of the sintering flue gas. Iron and steel enterprises usually use special flue gas purification systems, in which materials with adsorption function (such as activated carbon) are placed to adsorb sintering flue gas to achieve desulfurization and denitrification of sintering flue gas. [0003] see figure 1 , figure 1 Shown is a schematic structural diagram of a flue gas purification system ...
