Thermal power plant flue gas wet desulphurization system with multi-parameter monitoring function

Abstract

The invention discloses a thermal power plant flue gas wet desulphurization system with a multi-parameter monitoring function. The thermal power plant flue gas wet desulphurization system comprises adust remover, a heat exchanger, a booster fan, a wet desulphurization system body, a flue gas reheating device, a flue gas monitoring module and an intelligent adjustment control module which are sequentially arranged in the airflow direction. The wet desulphurization system comprises a wet desulphurization reaction tower, a desulfurizer slurry supply device, a circulating blower device and a diversion bed layer arranged in the wet desulphurization reaction tower. According to the invention, the wet desulphurization system is used for desulphurization of flue gas of a thermal power plant; thewet desulphurization reaction tower is designed; the advantage of high desulfurization efficiency of a wet desulfurization process can be brought into full play; the sulfur dioxide removal efficiencyand effect of the system are improved, desulfurization process parameters can be optimized by adopting a machine learning algorithm on the basis of big data by combining the intelligent adjustment control module, intelligent matching adjustment can be carried out on each piece of device, the energy consumption is greatly reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a flue gas wet desulfurization system of a thermal power plant with multi-parameter monitoring function. Background technique [0002] The wet process has fast reaction speed, high efficiency, and high utilization rate of desulfurization additives. For example, when lime is used as desulfurization agent, when Ca / S=1, the desulfurization rate can theoretically reach 90%, which is suitable for the flue gas of large coal-fired power plants Desulfurization. However, the existing wet desulfurization systems often have the problems of high power consumption and high cost. Matching and adjusting the equipment in the desulfurization system can greatly reduce power consumption. However, in the actual operation process, due to the large number of desulfurization system equipment, it is often difficult for humans to make accurate decisions on how to allocate between equipment ...

Problems solved by technology

However, in the actual operation process, due to the large number of desulfurization system equipment, it is often difficult for humans to make accurate decisions on how to allocate between equipment to ensure that the desulfurization tail gas meets the standard and achieve the best work efficiency, which often results in redundant energy consumption. , waste of resources

In addition, over the years, in the actual operation process, a large amount of precious actual operation data has been stored in the desulfurization system of the thermal power plant, but it has not been fully utilized under the existing technology
