Insulating gas drying and uniform mixing device for physics laboratory

Abstract

An insulating gas drying and uniform mixing device for a physical laboratory comprises: a support, wherein an upper drying part and a lower mixing part are arranged on the support; the upper drying part comprises a vertically-arranged drying cylinder, gas inlet pipe connectors are arranged on the front side and the rear side of the drying cylinder, and an upper cylinder cover and a lower cylindercover are arranged at the upper end and the lower end of the drying cylinder respectively; a left arc-shaped plate and a right arc-shaped plate with 90-degree arc center angles are coaxially arrangedin the drying cylinder, a molecular sieve cylinder rotationally connected to the outer circumferences of the left arc-shaped plate and the right arc-shaped plate is arranged in the drying cylinder, and an air outlet connected with an air inlet of the lower mixing part is formed in the center of the lower cylinder cover. The device is scientific in principle and unique in structure and not only candry single gas but also can dry and then mix two gases; the drying function and the mixing function are combined into an integrated structure, the drying modules (silicon-aluminum porous oxide) are replaced in a rotary mode and located at the working position and the regeneration position respectively; therefore, the device has the advantage of convenient operation and good drying and mixing effects.

Description

technical field [0001] The invention belongs to the technical field of physical experiments, in particular to an insulating gas drying and uniform mixing device for a physical laboratory. Background technique [0002] Sulfur hexafluoride (SF 6 ) is a good insulating gas for high-voltage installations. With the continuous development of society, the country pays more and more attention to environmental protection and energy saving and emission reduction. 6 The greenhouse benefits of gases are gradually being valued by environmental experts. A lot of research has been carried out at home and abroad to replace or reduce SF 6 Dosage, study found, SF 6 and N 2 The mixed gas is a good combination as an insulating gas for high-voltage switchgear. Various studies have shown that SF 6 and N 2 The mixed gas does not generate new poisons during discharge, and is less sensitive to electrode surface defects, so it has a good application prospect. [0003] At present, the high-volt...

AI Technical Summary

Problems solved by technology

[0003] At present, the instruments for experimenting and testing high-voltage insulating gas in the physics laboratories of colleges and universities are advanced and complete. Leak detection device, etc., in the SF 6 and N 2 Before testing the performance parameters of the mixed gas, the SF 6 and N 2 Drying and uniform mixing, the existing drying device and gas mixing device are separate structures, stored in the container after drying, and then released from the container to the mixing device for mixing, the operation is cumbersome, and there is a hidden danger of mixing impurity gas, and Dry and mix poorly
