Embodiment Construction

[0040] Taking the typical trolley-type sintering machine in China as an example, the present invention is described:

[0041] Detection of the present invention and hardware system see figure 1. The sintering mobile trolley contains the mixed raw materials being burned, and the lower part of the trolley is the fan system for extracting air to meet the combustion needs, mainly including sintering bellows, sintering flue and main exhaust fan. Since the trolley is spliced ​​by a number of mobile independent trolleys, there are gaps and movable connections between the trolley and the trolley workshop, the bellows and the trolley workshop, which makes it easy to generate air leakage in various parts, and it is difficult to use effective means. Leak detection. The invention proposes to realize the online calculation of the air leakage rate by means of sound collection in the sintering workshop. As shown in the figure, several sound signal collectors are installed in the workshop ...

Abstract

The invention discloses a sintering air volume control method. The method includes the following steps: establishing a sintering air leakage rate index offline model based on frequency characteristics; performing on-line calculation on air leakage rate indexes of a sintering machine based on an offline module; and performing closed-loop control on the sintering air volume based on the air leakagerate. The sintering air volume control method of the invention analyzes and calculates audio signals collected during the production process, obtains an evaluation value of the air leakage amount, anduses the air leakage rate evaluation value and an air volume detection value of the main exhaust fan air outlet as a feedback signal of the control system, and uses the running frequency of a motor of the sintering main exhaust fan as the adjustment amount to realize the online closed-loop control of the sintering air volume.

Description

Technical field: [0001] The invention relates to a sintering air volume control method Background technique: [0002] Iron ore sintering is an important link in the modern iron and steel metallurgical process. Its main production link is to ignite and burn evenly mixed small granular raw materials on a trolley-type sintering machine to fuse them into massive sinter. In order to ensure the strength and chemical composition of sinter agglomerates, the raw materials need to be fully burned on the sintering machine. The uniformly mixed small granular raw materials are evenly distributed in the form of a thick material layer on the sintering machine. In order to ensure the full combustion of the raw materials, the sintering machine is equipped with a bellows under the raw material layer and connected to the sintering main exhaust fan. The negative pressure generated by the main exhaust fan Press down to bring fresh air into the burning raw material layer. Due to the sealing str...
