Embodiment Construction

[0026] In order to further elaborate the technical means and effects that the present invention adopts for reaching the intended invention purpose, below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation, structure, features and effects of the present invention are described in detail as follows:

[0027] The principle of this application is that the essence of removing dissolved gas from transformer oil is a process in which dissolved gas diffuses from transformer oil to the vacuum area and tends to balance. Under the same volume, temperature, and pressure conditions, the larger the contact area, the faster the diffusion rate of dissolved gas, and the shorter the time required to reach the diffusion equilibrium. Therefore, the degassing time can be shortened and the degassing efficiency can be improved by increasing the contact area between the transformer oil and the vacuum area.

Abstract

The invention discloses an oil spraying vacuum degassing device for online monitoring of an oil chromatogram and an application method and relates to the field of separating materials through a chromatography. The oil spraying vacuum degassing device comprises a degassing cylinder for degassing, wherein the degassing cylinder is provided with an oil feeding opening for feeding oil and an oil returning opening for discharging the oil; the oil spraying vacuum degassing device further comprises a vacuum pump for realizing negative pressure of the degassing cylinder and a circulating solenoid valve for realizing circulating oil; the oil feeding opening and the oil returning opening are connected through a pipeline provided with the circulating solenoid valve; the oil feeding opening is connected with a spraying structure. When the oil spraying vacuum degassing device is used, pressure in the degassing cylinder is pumped to a complete vacuum negative-pressure state and then transformer oilis injected; then a plurality of times of circulation are carried out and filtered gas is pumped to finish concentration detection work; finally, an oil sample is recycled. The oil spraying vacuum degassing device disclosed by the invention has the beneficial effects that the degassing efficiency is improved and the degassing time is shortened; a bottom-end side face in the degassing cylinder is set to be a reversed tapered surface, so that the volume of residual oil can be effectively reduced and a condition that impurities deposited at the bottom of the inner side of the degassing cylinder are pumped into the pipeline can be avoided.

Description

technical field [0001] The invention relates to the field of material separation by chromatography, in particular to an oil spray vacuum degassing device and a use method for on-line monitoring of oil chromatography. Background technique [0002] At present, there is no technology to directly detect the dissolved gas content in transformer oil at home and abroad. Whether it is laboratory testing equipment or on-line testing equipment installed on site, the gas dissolved in transformer oil must be released before measurement. Removing dissolved gas from transformer oil is the key and necessary prerequisite for rapid detection and accurate measurement. The most commonly used vacuum degassing methods for removing dissolved gas from transformer oil include reciprocating bellows or piston type and magnetic drive stirring type, all of which have disadvantages such as complex structure, long degassing time, and low degassing efficiency.
