Description

Technical Field

[0001] The present invention relates to the technical field of oil-water separation, and more specifically, to a high-frequency electromagnetic field generating circuit based on high-frequency coalescence oil-water separation technology. Background Art

[0002] In the field of oil-water separation technology, although traditional separation methods such as gravity separation and centrifugal separation can achieve the separation of oil and water to a certain extent, they often have problems such as low separation efficiency, long processing time, and poor separation effect on tiny oil droplets. Especially when dealing with oil-water mixtures with low oil content and small oil droplet size, traditional methods often find it difficult to achieve ideal separation effects.

[0003] With the continuous development of industrial technology, the requirements for oil-water separation technology are getting higher and higher. Especially in the fields of oil extraction, chemical production, environmental protection treatment, etc., efficient and fast oil-water separation technology is particularly important. Therefore, exploring new oil-water separation technology and improving separation efficiency and effect have become one of the current research hotspots.

[0004] As an emerging oil-water separation method, high-frequency coalescence oil-water separation technology has received widespread attention in recent years. This technology uses high-frequency electromagnetic fields to coalesce and separate oil droplets in oil-water mixtures. Through the action of high-frequency electromagnetic force, tiny oil droplets are aggregated into larger oil droplets, which facilitates subsequent separation and recovery. Compared with traditional methods, high-frequency coalescence oil-water separation technology has the advantages of high separation efficiency, short processing time, and good separation effect on tiny oil droplets.

[0005] However, in practical applications, the implementation of high-frequency coalescence oil-water separation technology requires a set of stable and reliable high-frequency electromagnetic field generating circuits to support it. Traditional electromagnetic field generating circuits often have problems such as complex structure, high energy consumption, and poor stability, which make it difficult to meet the needs of high-frequency coalescence oil-water separation technology. Therefore, designing an efficient, stable, and reliable high-frequency electromagnetic field generating circuit has become the key to realizing high-frequency coalescence oil-water separation technology.
