Description

Technical Field

[0001] The invention relates to the technical field of oil fume purification, and in particular to an intelligent oil fume purification method. Background Art

[0002] With the improvement of people's living standards and the enhancement of environmental awareness, the issue of oil fume purification has received more and more attention in the catering, food processing and other industries. In these fields, traditional oil fume purification methods face many challenges. Early oil fume purification technologies were relatively simple. For example, relying solely on filter filtration, only larger oil fume particles can be intercepted, and tiny oil mist, harmful gases and other pollutants are powerless. In some large restaurants, the oil fume produced during the cooking process has complex components, not only grease particles, but also harmful gases such as volatile organic compounds. A single filter filtration cannot meet the needs of comprehensive purification. Although electrostatic adsorption technology can remove some tiny particles, it is prone to discharge abnormalities in high humidity environments, resulting in a significant decrease in purification efficiency. Traditional electrostatic purification equipment has fixed working parameters and cannot be adjusted in real time according to actual oil fume conditions. When the oil fume concentration is low, the equipment still runs at high power, resulting in energy waste. ; However, when the oil fume concentration suddenly increases, the purification intensity cannot be increased in time, affecting the purification effect. In terms of equipment maintenance, traditional methods lack scientific basis and are often maintained at a fixed time cycle, such as regularly replacing filters and cleaning electrodes. The actual amount and composition of oil fume generated will vary depending on factors such as cooking methods and types of ingredients. Fixed-cycle maintenance may lead to untimely or excessive maintenance. The filter may be blocked prematurely due to excessive oil fume concentration in actual use, but it cannot be replaced in time before the fixed maintenance cycle, affecting the purification effect; or when the oil fume concentration is low, the filter is frequently replaced at a fixed cycle, which increases operating costs. With the development of machine learning technology, some methods have emerged that attempt to apply it to the field of oil fume purification, but most of them simply use machine learning to monitor oil fume concentration, fail to make full use of multi-source data for in-depth analysis, and cannot comprehensively and intelligently generate the optimal purification strategy.

[0003] However, the current common solutions have many shortcomings, including: the existing oil fume purification equipment has not introduced machine learning algorithms at all, cannot make full use of data for intelligent analysis, can only rely on preset fixed rules to operate, lack of flexibility and adaptability, and some simple oil fume purifiers only perform purification operations at fixed time intervals without considering changes in the actual oil fume situation.
