Silica gel regeneration device

Abstract

The invention discloses a silica gel regeneration device, comprising a drying oven and a silica gel storing disc, wherein the drying oven is provided with an open door and the silica gel storing disc is arranged in the drying oven; a heat-insulting layer is arranged on the inner surface of the drying oven; an air inlet is arranged at the bottom of the drying oven and an air outlet is arranged at the top of the drying oven; and a heating mechanism is arranged at the lower part of the silica gel storing disc. According to the invention, the moistened silica gel is placed into the silica gel storing disc and then the silica gel storing disc is placed in the drying oven to be dried by hot air, the silica gel regeneration device has the advantages of simple structure, convenience for use, good energy-saving effect and low labor intensity, so that the silica gel regeneration device is particularly applicable to drying and regenerating the silica gel, and wastes caused by abandoning of the moistened silica gel are eliminated.

Description

technical field [0001] The invention relates to the technical field of regeneration devices for adsorption materials in transformers, in particular to a silica gel regeneration device. Background technique [0002] The respirator (also known as the moisture absorber) of the transformer is filled with an adsorbent inside, and the adsorbent is made of silica gel, and the color-changing silica gel is often placed in it (after the silica gel is impregnated with a 3% cobalt nitride aqueous solution, it is dried at a high temperature of 120-140°C for 4 ~6h, when the water evaporates and turns blue), when the color-changing silica gel changes from blue to light red, it indicates that the adsorbent has been damp and must be replaced and dried. Transformers mostly use blue silica gel, which is blue or light blue glass-like spherical particles in appearance. It has the function of silica gel adsorption and moisture resistance, and can change its color from blue to purple and finally t...

AI Technical Summary

Problems solved by technology

[0004] Issues that should be paid attention to in the regeneration of silica gel: When drying and regenerating, attention should be paid to gradually increasing the temperature, so as not to cause the rubber particles to burst due to severe drying and reduce the recovery rate.
