Abstract
The invention discloses a desulfuration adsorbent for transformer deteriorated oil and a preparation method thereof, and belongs to the field of solid adsorbent combinations or filtering additive combinations. The desulfuration adsorbent is used for solving the problems that an existing adsorbent is poor in adsorption effect and difficult to treat to cause high environment pressure. The desulfuration adsorbent for the transformer deteriorated oil is in a particle shape, the specific area is 300-350 m<2>/g, and effective components comprise, by weight, 20-50 parts of zeolite molecular sieves, 5-40 parts of aluminum oxide and 5-40 parts of zinc oxide. The desulfuration adsorbent is nontoxic, nonflammable, free from danger like burning explosion in the waste oil treatment process, low in overall cost, small in pollution to the environment and beneficial for protecting physical health of workers.
Description
Technical field
The invention belongs to solid sorbent compositions or filtration adjuvant compositions field, specifically, relate to oily desulfuration adsorbent of a kind of transformer deterioration and preparation method thereof.
Background technology
Transformer oil is in the running of transformer, and due to impacts such as the high temperature in foreign substance pollution or running, electromagnetic field, metal catalytics, transformer oil can be oxidized, and then makes to plant in oil that impurity increases, oil colours muddy, finally becomes the abandoned oil of deterioration.Transformer long-play, the element sulphur in transformer oil is easy to transformer or connected copper part reacts, and then is corroded by copper part.Processing method more common in prior art adopts H
2sO
4-carclazyte method, Acid-Base-carclazyte method is adsorbed transformer oil, but mainly there is following defect: in processing procedure, use the aqueous chemical such as acid, alkali material, potential potential safety hazard is there is concerning operator, and some acid sludges and alkaline residue can be produced, cannot disposal and utilization, larger pressure is caused to environment.
Summary of the invention
For solving the problem, the invention provides a kind of advantages of good adsorption effect, to deteriorated oily desulfuration adsorbent of the transformer that environmental pressure is little and preparation method thereof.
The oily desulfuration adsorbent of transformer deterioration of the present invention is graininess, and specific area is 300-350m
2/ g, active princlple comprises zeolite molecular sieve 20-50 part, aluminium oxide 5-40 part, zinc oxide 5-40 part, and described number is weight portion.
Preferably, described desulfurization adsorbent for transformer oil comprises the active principle of following weight portion: zeolite molecular sieve 40 parts, 30 parts, aluminium oxide, 30 parts, zinc oxide.
The preparation method that another object of the present invention is to provide a kind of desulfurization adsorbent for transformer oil comprises the following steps:
(1) zeolite molecular sieve, aluminium oxide, zinc oxide are added in aqueous slkali mix;
(2) with forming machine, gained mixture in (1) is made the particle that particle diameter is 2-3mm;
(3) step (2) gained particle is placed in baking oven and bakes and banks up with earth 2 hours at 70 DEG C; Then quick temperature is increased to 700 DEG C, dries and within 1 hour, namely obtain dried particles produce product.
Preferably, aqueous slkali pH=8-9 used in step (1), in aqueous slkali used be preferably NaoH.
Compared with prior art, the invention has the beneficial effects as follows:
(1) desulfuration adsorbent of the present invention is nontoxic, nonflammable, and wait dangerous without firing in waste oil disposal process, holistic cost is lower, and environmental pollution is little, and is conducive to the healthy of protection staff;
(2) absorbent particles prepared by the present invention, has larger specific area, advantages of good adsorption effect;
(3) adsorbent prepared by the present invention, has stronger adsorption capacity, and the transformer oil after sorbent treatment can reach the standard of fresh oil; The preparation method of adsorbent is fairly simple, can save cost of manufacture, and the using method of adsorbent is also comparatively simple, and can use filter plate, filter paper or filter cloth and use, be also directly use adsorbent to be allowed to condition in transformer oil natural subsidence process to play suction-operated.
