Abstract

The invention provides an automatic control method and device for a lime kiln. The method comprises the steps of determining the heat value of gas; according to the determined heat value of gas and a predetermined yield requirement of a lime kiln, determining the amount of air for achieving the predetermined yield; controlling the rotating speed of fans according to the determined amount of air. Air distribution of a lime kiln is controlled based on the heat value of gas and yield requirements, which are objective, so that the accuracy and instantaneity of air distribution control can be guaranteed and the problem of non-reasonable air distribution control caused by calculating the amount of air solely based on temperature or manually can be solved. The method and the device can control the air distribution of lime kilns in real time accurately, so that the degree of automation of the production of lime kilns can be effectively, the requirements of technological procedures can be met and the production efficiency of lime kilns and product quality can be improved.

Description

technical field [0001] The present invention relates to lime kilns, and in particular, to an automatic control scheme for lime kilns. Background technique [0002] A lime kiln is a kiln for calcination by burning fuel. At present, with the increasing demand for limestone in industrial production, lime kilns are also being used more and more. In order to improve the production efficiency of lime kiln, reduce energy consumption, reduce tail gas emission and improve product quality, many improvement schemes have been proposed. Moreover, due to the increasing demand for automation in today's production process, some people have proposed an automatic control method for lime kilns. [0003] In the production process of the lime kiln, it is necessary to control various aspects of the lime kiln, such as feeding, unloading, and air distribution. Among them, the control process of feeding and unloading is relatively simple, and only relatively simple information needs to be collect...
