Problems solved by technology

The problem with this method is that once the oil storage tank is full of oil and water, the waste oil will first flow to the pond, land or urban sewage pipe network through the pipeline, causing serious pollution to the environment
[0004] 1. Oil and water are mixed, the emulsification is serious, the oil content is relatively high, and the sewage forms a relatively stable emulsion, which is difficult to break the emulsion;
[0005] 2. The aging time of waste oil-containing sewage is long, generally 2-10 years, and the stability is extremely strong, so it is difficult to completely separate oil and water;
[0...

Abstract

The invention a high oil-absorbing resin, which is prepared from monomer, cross-linking agent, pore forming agent, initiator and dispersant at a ratio of 100:(1.2-2.8):(10-50):(0.2-2):(0.1-0.5) by initiating suspension polymerization in a nitrogen gas protective atmosphere via free-radical. The high oil-absorbing resin is adopted as an adsorbent in abandoned oil recovery treatment, for example, the high oil-absorbing resin which accounts for 2.5wt%-10wt% of the oil amount of a waste transformer is added to an oil water mixture of the waste transformer, and the waste transformer oil in waste water can be absorbed by resin and condensed into gel blocks, so as to separate from the water. The gel blocks containing the waste transformer oil is removed by filtering with a filter screen. The tank water can be discharged in a pollution-free manner. The oil product is recovered from the gel blocks containing the oil by distillation. The resin can be utilized repeatedly. The abandoned oil recovery treatment method adopting the high oil-absorbing resin has the advantages of simple process and low processing cost, and conforms to the environmental requirements.

Description

1. Technical field [0001] The invention relates to a body-shaped macromolecule and its application, in particular to a high-absorbing macromolecule and its application, in particular to a high oil-absorbing resin and its application. 2. Background technology [0002] At present, for the treatment of transformer waste oil, it is conventional to build an oil storage tank next to the transformer. The waste oil leaked from the transformer and rainwater are injected into the oil storage tank together. float on the water. The problem with this method is that once the oil storage tank is full of oil and water, the waste oil will first flow to ponds, land or urban sewage pipe network through pipelines, causing serious pollution to the environment. Since most of the large-scale substations are built in the suburbs, once the dirty oil (water) from the oil storage pool flows into farmland and fish ponds, it will cause crops to die and fish to be poisoned; As a result, fish ponds can ...
