Embodiment

[0029] The oil pump, the plate-and-frame oil filter, the vacuum oil filter, and the tank body with the oil inlet and the oil outlet are connected to the transformer through the oil pipe. Add nano-copper-loaded activated carbon adsorbent (10 kg, placed in the middle layer of the combined adsorption tank) and XDK-02 type (20 kg, placed on the lower and upper layers of the combined adsorption tank on average) adsorbents in the tank, and introduce the existing degraded Transformer oil (sulfur content 1542.68 mg / l), after heating for 40 minutes, the oil temperature reaches 60°C, and the temperature is constant; then start to filter the oil according to the process of "oil tank-oil processor-oil filter", and oil The flow is basically full of oil, and the pressure of the plate filter is about 0, indicating that the oil filter is flowing smoothly.

Abstract

The invention discloses an adsorption device capable of regenerating an adsorbent on site and used for transformer oil regeneration. The adsorption device comprises a plate frame oil filter, a vacuum oil filter and a tank body provided with an oil inlet and an oil outlet. The adsorption device is characterized in that the tank body is internally provided with an upper filter screen and a lower filter screen; a middle filter screen I and a middle filter screen II are sequentially arranged between the upper filter screen and the lower filter screen; a decolorizing adsorbent layer is arranged between the upper filter screen and the middle filter screen I; a dielectric loss reduction adsorbent layer is arranged between the middle filter screen I and the middle filter screen II; a desulfurization adsorbent layer is arranged between the middle filter screen II and the lower filter screen; the tank body above the upper filter screen is provided with a detergent inlet; the bottom of the tank body is provided with a hot air inlet, and the top of the tank body is provided with a hot air outlet; the oil inlet is formed in the bottom of the tank body, and the oil outlet is formed above the upper filter screen. According to the adsorption device, degraded transformer oil can be comprehensively regenerated in the adsorption device, and a cleaning and heating device can be utilized for activating the adsorbent reaching adsorption saturation again, so that the adsorbent is recycled on site.

Description

Technical field [0001] The invention relates to various deteriorating oil regeneration equipment in the electric power industry, in particular to an adsorption device used for transformer oil regeneration and capable of regenerating adsorbents on site. Background technique [0002] Transformer oil is a mixture of various hydrocarbons in which positively charged hydrogen elements and negatively charged carbon elements are combined in a chain or ring structure. The oil is non-polar when the center of gravity of the electrons moving in a circle around the positive charge coincides with the center of gravity of the charge. When the compound is combined in the saturated state of carbon, it is called a saturated compound, also known as a non-polar compound. When carbon elements are combined with other elements to form aromatic hydrocarbons with saturated bonds, but olefins are mixed in, they are called unsaturated compounds, also known as polar compounds. Polar compounds have ...
