The automatic control system of environment-friendly lime kiln has more advantages

When the environmental protection lime kiln was just developed and put into use, it was a traditional and original way. This way consumed much manpower and material resources, so it needs to be improved to achieve automatic control. With the defect of traditional lime kiln, we focus on the research of automatic control system of environmental protection lime kiln. Today, we will carefully study the advantages.

The automatic control system of environmental protection lime kiln is an intelligent program control of lime kiln designed by designers after years of theory and practice. It can be equipped point-to-point according to the actual situation on site and the actual requirements of customers. At present, it is widely used in the automatic control of mechanized environmental protection lime kiln and the automatic control of calcium hydroxide in our company. Both can realize online and remote operation, automatic and manual operation, and facilitate user detection and control.

Design principle

On the basis of ensuring the stability and reliability of the system, the system uses advanced programmable control technology and embedded industrial computer technology to achieve data acquisition, display and control according to industrial standards and customer requirements, fully meeting the requirements of automatic operation. It has the advantages of simple operation, low operating cost and high degree of automation, so that people can realize the operation of the whole set of equipment, And important electrical parts are imported or joint venture products, striving to provide customers with a stable, reliable and reliable automatic control system.

1. System control

System control can be broadly divided into three categories: frequency active power control, voltage reactive power control and system operation.

In addition to the relay protection device and system stability device in emergency, the system operation is still a problem to be studied in the future, especially the automatic operation system and theoretical discussion between layers and systems.

Since the regulation effect will affect the whole system, the frequency adjustment shall be controlled by the central controller. In the central control station, the load frequency control, economic load distribution and active power predictive control tracking load change of the system will be carried out by computer or part of analog devices.

2. System monitoring

The purpose of system monitoring is mainly to monitor the state of the system and the process of control, so as to make it easier for operators to start, interrupt and correct the control, so as to make it easier for operators to start, interrupt and correct the control. Therefore, system monitoring and system control are closely related, especially in emergency and recovery situations.

At the current level of automation, only the state monitoring represented by the original system wiring simulation panel and operation console is transferred to the use of computer to detect the change of system state, verify the upper and lower limits of measured data, and then display the structure in color CRT.
