Example Embodiment

[0018] An expert control method for lime double-chamber kiln calcination includes the following steps:

[0019] a. Determine the amount of operation and the controlled amount: the calcination process of the lime double-chamber kiln can be divided into two lines: the material path and the gas path. The direction of the material path is: the lime raw meal enters the kiln chamber preheating section under the action of the feeding system. Then under the action of gravity, it enters the calcining section for calcination, and finally the finished product is produced after the cooling section; the direction of the gas path is exactly opposite to the direction of the material path under the action of the exhaust fan at the kiln tail; in the above process, the double-chamber kiln is calcined The quality of lime directly affects the quality and productivity of lime, and the quality of calcination mainly depends on the accurate control of the temperature in the double-chamber kiln and the co...

Abstract

The invention discloses an expert control method for burning a double-chamber lime furnace. The method comprises the following steps: determining operation quantity and controlled quantity, collecting and classifying data, identifying models, obtaining prediction models, and performing optimal solution; the method can solve the problem that coupling among variables, system nonlinearity, time lag and temperature in the furnace cannot be accurately measured, the excellent control effect can be realized, the coal injection quantity of the controlled quantity and the aperture of the furnace tail blower are automatically adjusted according to the set values of NOx and O2 contents of the controlled quantity for burning the double-chamber lime furnace, so that the actual value of the controlled quantity can quickly follow up the set value, the operating quality during the burning process of the double-chamber lime furnace is increased, the operation during the burning process is relatively steady, reasonable and accurate, and the labor intensity of workers is also reduced.

Description

technical field [0001] The invention belongs to the technical field of advanced control methods for lime double-chamber production process, and relates to an expert control method for calcination of lime double-chamber kiln. Background technique [0002] Lime double-chamber kiln calcination is a very typical and important link in the lime production process, and its operation quality directly affects the quality, production capacity and production cost of lime. The calcining operation of lime double-chamber kiln depends largely on its control method, so the advanced control method of lime double-chamber kiln calcining has attracted more and more attention and attention at home and abroad. [0003] The difficulty in the control of lime double-chamber kiln calcination mainly lies in its complex variable coupling, nonlinearity and time delay, which makes it difficult to obtain better control methods such as traditional experience adjustment method, PID adjustment method, fuzzy ...
