Automatic uniform discharging control method and device

Abstract

The invention discloses an automatic uniform discharging control method and device. According to the method, when discharging operation is carried out for buffering bins, material levels of the buffering bins are detected, and actual material values of the buffering bins are obtained, so that the material level state of the buffering bins is determined. When the buffering bins in the low materiallevel state exist, discharging operation is carried out on the buffering bins in the low material level state preferably, and when the buffering bins in the high material level state exist, discharging operation on the buffering bins in the high material level state is prohibited. Compared with the prior art, the discharging sequences of all the buffering bins are adjusted on the basis of the material level state of the buffering bins, the discharging amount of all the buffering bins can be controlled, all the buffering bins can be discharging uniformly, and the buffering bins do not need to be distributed manually again.

Description

technical field [0001] The present application relates to the technical field of flue gas purification, and more specifically, to an automatic discharge control method and device. Background technique [0002] The activated carbon adsorption tower system is one of the most critical links in the entire flue gas purification system for desulfurization, denitrification, dioxin removal, heavy metal removal, dust removal and other trace harmful flue gas components. see figure 1 A schematic structural diagram of an adsorption tower system is shown. The adsorption tower system generally consists of multiple adsorption towers and multiple buffer bins, and each adsorption tower corresponds to a buffer bin. How to uniformly unload the material (activated carbon) into the buffer bin of the adsorption tower is the most complicated, tedious, and energy-intensive link for system operators. System operators must always pay attention to whether the level of activated carbon in the buffer ...

Problems solved by technology

In the existing unloading plate drive, the time control method is generally adopted. According to a certain unloading sequence, the unloading of the conveyor is controlled based on the set unloading time. The longer the unloading time of the unloading plate, the greater the amount of unloading. Many, but if there is an unbalanced material level in each buffer bin due to unloading, some bins are full and some are about to be empty, the time control method must be stopped, and then the buffer bins are re-discharged manually, and it cannot be automatically Realize uniform unloading of each buffer bin
