Problems solved by technology

However, this kind of degraded oil adsorbent has an irregular block shape and poor hardness. After the degraded oil is processed, it is easily broken into powder, which cannot be used any longer and has to be discarded, which not only causes waste, but also pollutes the environment.

Abstract

The invention relates to a method for producing adsorbent particles for processing power system deteriorated oil, especially transformer waste and old oil. The adsorbent particles produced through the method of the invention utilize characteristics of attapulgite and combine a deteriorated oil adsorbent, so adsorption processing functions and effects of the original deteriorated oil adsorbent to deteriorated oil are improved, and the adsorbent which won't deform and fragment after use can be continuously used. The method has the advantages of production efficiency improvement, production cost saving, and environmental pollution reduction.

Description

technical field [0001] The invention relates to a method for producing adsorbent particles used for treating degraded oil in a power system, especially transformer waste oil. Background technique [0002] With the development of the power industry, the demand for power oil continues to increase, and the power oil will inevitably deteriorate under the operating conditions of a certain temperature, atmosphere and electromagnetic field. The active ingredients of deteriorated power oil are generally high, and it is uneconomical to dump it or downgrade it for use. Regeneration of degraded power oil is an effective saving measure, which can produce significant economic benefits and protect the environment. Using high-efficiency adsorbents to regenerate degraded power oil not only has low fuel consumption and simple process, but also the quality of regenerated oil is close to that of new oil, which saves a large amount of production costs for enterprises, saves precious oil resour...
