Description

Technical Field

[0001] This utility model relates to the field of insulating oil production technology, specifically to a purification device for the pretreatment of insulating oil fine filtration process. Background Technology

[0002] The main purposes of fine filtration of insulating oil are: 1) Improving oil purity: Fine filtration removes tiny particles, suspended solids, impurities, and any metal debris that may be present in the insulating oil, significantly improving its purity and cleanliness. This is crucial for ensuring the normal operation of electrical equipment and extending its service life. 2) Ensuring insulation performance: The primary function of insulating oil is to provide electrical insulation. Fine filtration removes contaminants that may affect insulation performance, such as moisture, dust, and carbides, ensuring the insulating oil has good insulation properties and preventing electrical equipment malfunctions due to poor insulation. 3) Improving heat dissipation efficiency: Insulating oil also plays a role in heat dissipation in electrical equipment. Finely filtered insulating oil flows more smoothly, effectively carrying away the heat generated during equipment operation, helping to maintain the normal temperature of the equipment and preventing overheating. 4) Extending equipment maintenance cycles: The service life and performance stability of finely filtered insulating oil are significantly improved, reducing equipment failures and maintenance needs caused by oil quality issues. This helps reduce maintenance costs and extend the overall service life of the equipment.

[0003] The main function of the impurity removal device in the pretreatment of insulating oil fine filtration is to remove larger impurities such as particulate matter and metal fragments from the insulating oil. By removing impurities, the quality and purity of the insulating oil are improved, providing high-quality raw materials for the subsequent fine filtration process.

[0004] Existing impurity removal devices used in the pretreatment of insulating oil fine filtration have been found to have shortcomings. Firstly, they cannot pre-adsorb impurities with an adsorbent before filtration, thus failing to intercept most impurities. This leads to easy clogging of the filter pores, affecting filtration efficiency. Secondly, they cannot achieve regular and rapid replacement of adsorbed particles. Therefore, optimization and improvement are necessary. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned problems in the traditional technology and provide a purification device for the pretreatment of insulating oil fine filtration process.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

The inner cavity of the first treatment box is divided into an upper filtration zone and a lower impurity collection zone by the impurity guide baffle. Several rows of staggered impurity baffles are installed in the upper filtration zone. The inner cavity of the second treatment box is divided into a left filtration zone, a middle adsorption zone, and a right collection zone by the solid baffle and the perforated baffle. An oil inlet pipe is installed at the bottom left side of the upper filtration zone.
