[0004] In the existing technology, the environmental protection equipment used for flue gas treatment has only realized basic automation, that is, the use of PLC / DCS system can complete equipment sequence control and start-stop chain under the condition of small fluctuations in working conditions and few external disturbance variables. The automatic control of the control, through the PID algorithm, can realize the simple single-variable closed-loop control of temperature control, liquid level control, pressure control, etc., and then realize the automatic operation of the equipment; For the closed-loop control of disturbance variables, it is difficult to achieve a stable and precise control level by using the PID algorithm, and it is impossible to achieve optimal control and fail to meet the requirements of stable and economical operation
[0005] On the other hand, the outlet flue gas online monitoring system and the automatic control system are two independent systems. The outlet flue gas monitoring system generates the emission results of flue gas pollutants through data monitoring, storage and analysis, and the automatic control system realizes the alarm through the setting of the operating status threshold. Or manual control, this method leads to the separation of the two functions of data monitoring and automatic control, and cannot be linked, so that the automatic operation optimization control of the entire set of equipment cannot be performed.

Abstract
The invention discloses a flue gas treatment intelligent operation optimization control system and method, and the system comprises a flue gas treatment device which is used for achieving the treatment of pollutants in industrial flue gas; the system control unit is used for detecting operation data of each flue gas treatment device and sending the operation data to the edge controller; receiving an adjusting instruction of the edge controller, and adjusting the operation data of each flue gas treatment device; the edge controller is used for receiving the operation data of each flue gas treatment device, and when the operation data exceed a set safety threshold range, an adjusting instruction is sent to the system control unit, so that the operation data of each flue gas treatment device is within the safety threshold range; and the hyper-converged server is used for taking the hyper-converged infrastructure as a core, constructing corresponding virtual machines according to different business functions, establishing a unified server cluster, and realizing comprehensive picture service, expert system service, operation management service and database service based on the data uploaded by the edge controller.
Description
technical field [0001] The invention relates to the technical field of intelligent operation of environmental protection equipment, in particular to an intelligent operation optimization control system and method for flue gas treatment. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] At present, the non-electric industry has large fluctuations in working conditions and complex smoke emission characteristics, and has gradually become a key technical field for air pollution prevention and control. [0004] In the existing technology, the environmental protection equipment used for flue gas treatment has only realized basic automation, that is, the use of PLC / DCS system can complete equipment sequence control and start-stop chain under the condition of small fluctuations in working conditions and few external disturbance variables. The autom...
