Abstract

The invention discloses a transformer deteriorated oil adsorbent and a preparation method thereof, and belongs to the field of solid adsorbent combinations or filtering additive combinations. The transformer deteriorated oil adsorbent is used for solving the problems that an existing adsorbent is unsafe and pollutes the environment seriously. The transformer deteriorated oil adsorbent comprises, by weight, 30-40 parts of aluminum oxide, 20-40 parts of sodium silicate and 20-30 parts of aluminum chloride. The prepared adsorbent is composed of inorganic components, nontoxic, nonflammable and free from danger like burning explosion in the waste oil treatment process; the preparation method of the adsorbent is simple, low in cost and free from environment pollution; the adsorbent has a large specific area and good adsorption and purification effects.

Description

technical field [0001] The invention belongs to the field of solid adsorbent composition or filter aid composition, and in particular relates to a transformer degraded oil adsorbent and a preparation method thereof. Background technique [0002] During the operation of the transformer, the transformer oil will be oxidized due to foreign matter pollution or the influence of high temperature, electromagnetic field, metal catalysis, etc. during the operation, and then the impurities in the oil will increase, the oil will be turbid, and finally become deteriorated waste oil. The more common processing method in the prior art is to adopt H 2 SO 4 - The clay method and the acid-alkali-clay method are used to adsorb transformer oil, but there are mainly the following defects: liquid chemical materials such as acid and alkali are used in the treatment process, which has potential safety hazards for the operator and will produce some Acid slag and alkali slag cannot be treated and ...
