Intelligent control system for boiler water supply

Abstract

The invention discloses an intelligent control system for boiler water supply. The intelligent control system comprises a signal processing module, a feedback adjusting module, a detection analysis module, a touch screen, an alarm module, a signal receiving and transmitting module, a boiler body, a liquid level transmitter, an energy saver, a water supply pump, a water supply pipe, an adjusting valve, a lead screw, a guide rod, a proportional valve, a water conveying pipe, a lifting block, a worm, a rotating shaft, a worm wheel and a limiting groove. According to the intelligent control system, parameters in the working process of equipment are monitored in real time, then the processing module utilizes a multi-stage function PID algorithm to accurately control the pressure, the flow, theproportional valve and the like, stability and reliability are achieved, and unnecessary energy consumption can be saved; and compared with a traditional water supply system, the system is beneficialto energy saving, the collected data are analyzed and calculated through the detection analysis module, when the data of the equipment are abnormal, an alarm is given in time, timely overhauling and maintenance are facilitated, larger economic losses are avoided, and the safety performance of the equipment can be improved.

Description

technical field [0001] The invention relates to the technical field of boiler feed water systems, in particular to an intelligent boiler feed water control system. Background technique [0002] In recent years, the government has continuously increased the layout and planning of the waste incineration power generation industry to promote the rapid development of my country's municipal solid waste incineration power generation industry. The power consumption of the power plant itself accounts for about 10% of its installed capacity. The equipment is not only an important auxiliary equipment, but also a large electricity consumer, so the economy and safety of the water pump operation are particularly important. [0003] In the traditional single-impulse and three-impulse boiler feed water control systems, the boiler feed water pump can only operate under the maximum working condition parameters, and the pressure of the main pipe is always under the highest maximum working condi...

AI Technical Summary

Problems solved by technology

[0003] In the traditional single-impulse and three-impulse boiler feed water control systems, the boiler feed water pump can only operate under the maximum working condition parameters, and the pressure of the main pipe is always under the highest maximum working condition pressure, causing the boiler feed water pump to do a lot of useless work during operation. The waste of electric energy resources greatly increases the operating cost, and when the system works under high temperature and high pressure for a long time, once the equipment is abnormal, it will cause great losses, and even threaten the life and health of the staff, reducing The safety of the system is ensured. At the same time, the length of the system pipeline is very long, and the height of the installation plane is different. Therefore, it is necessary to design support legs of different heights for support, and the support legs are fixed after installation and cannot be reused, which increases the equipment. cost of use
