Abstract
The utility model relates to an energy-saving control system of a coal mill, which comprises a microprocessor. The microprocessor is connected with a material level detector of the coal mill, a material level controller of the coal mill, an outlet temperature and system air pressure controller and a fault diagnosis device of a milling system. Based on the operating parameters of the coal mill, the amount of coal stored in the coal mill and the operating status of the milling system can be detected, and faults of the milling system can be diagnosed. The energy-saving control system of the coal mill has the advantages that the operation is stable, the maintenance can be facilitated, and energy can be saved.
Description
Technical field
The utility model relates to a kind of energy-saving control system of coal pulverizer.
Background technology
Coal pulverizer internal memory coal measurement amount technology has current method, power method, pressure differential method, vibratory drilling method, noise method etc., and the product of formation has electric ear, vibrational loading measuring instrument or device, noise load measurement appearance or device, charge level detector or device etc.The pulverized coal preparation system automatic control technology comprises: coal supply automaton or system, level of material for ball mill supervising device or system, three loop control systems, pulverized coal preparation system Based Intelligent Control, milling system optimized control etc.
But in use since coal load quantity measure effectively solved, to be lacked the through engineering approaches design that gears to actual circumstances, control performance can't be steady in a long-term, system is difficult to problems such as maintenance; Cause the devoting rate of utilization rate and control loop of automatic control lower; The economy of pulverized coal preparation system operation can't be guaranteed, and makes the automatic control of pulverized coal preparation system and optimization operation remain the difficult problem that the puzzlement electric power enterprise is produced.
Summary of the invention
In order to overcome the deficiency of above-mentioned prior art, the purpose of the utility model has been to provide a kind of energy-saving control system of coal pulverizer, have stable, be convenient to safeguard and energy-conservation characteristics.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of energy-saving control system of coal pulverizer; Include microprocessor; Microprocessor links to each other with the coal pulverizer Charge level measurer through the coal pulverizer charge level controller, and microprocessor and outlet temperature link to each other with system blast controller, pulverized coal preparation system fault diagnosis device.
Compared with prior art,, reduce coal pulverizer unit consumption 8%-25%, improve pulverizer capacity >=10%, reduce coal pulverizer steel consumption >=10% because coal pulverizer has adopted the utility model to control.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explain.
Referring to accompanying drawing; A kind of energy-saving control system of coal pulverizer; Include microprocessor 1, microprocessor 1 links to each other with coal pulverizer Charge level measurer 2 through coal pulverizer charge level controller 3, and microprocessor 1 and outlet temperature link to each other with system blast controller 4, pulverized coal preparation system fault diagnosis device 5.
Coal pulverizer Charge level measurer 2 is passed to microprocessor 1 with the coal amount detection data of material level through charge level controller 3, and 1 pair of data of microprocessor are handled the back and sent control coal amount signal to charge level controller 3.
To realizing coal load quantity (material level) and the detection of pulverized coal preparation system running status in the coal pulverizer on the basis of coal pulverizer operational factor, carry out the fault diagnosis of pulverized coal preparation system simultaneously.
Automatic control to material level, outlet temperature and system's blast in the coal pulverizer.Even when changing in system, still can guarantee control performance and regulation quality, realize safety, the stable operation of system.
Optimize the running status of material level, outlet temperature and system's blast in the coal pulverizer, the relation of coordinating that coal-grinding is exerted oneself, drying is exerted oneself and ventilating and exert oneself realizes the economical operation of pulverized coal preparation system.
Microprocessor utilizes original DCS software and hardware to realize the pulverizing process optimal control, and control incorporates DCS fully, has simplified operation, reduces maintenance workload.
