Description

A cleaning sewage treatment system for decommissioned composite insulators

technical field

The utility model belongs to the technical field of composite insulators, in particular to a cleaning sewage treatment system for decommissioned composite insulators.

Background technique

Composite insulators are organic materials. During operation, the sheath material of composite insulators will be subjected to combined effects of temperature, pollution, humidity, partial discharge or high field strength, resulting in surface contamination. The pollution sources of composite insulators can be divided into industrial and domestic pollution sources, soil pollution sources, transportation pollution sources, etc. In addition, the deposition of pollution is also closely related to the structure and surface finish of the insulator itself. The complexity of the pollution formation method also leads to a wide variety of natural pollution components on the surface.

The surface pollution of decommissioned composite insulators is mainly composed of water-soluble and water-insoluble salts, oxides, and hydroxides, as well as a small amount of organic matter such as oil, which is difficult to remove by simple washing. At present, the cleaning agents used in the surface cleaning system of decommissioned composite insulators are mainly anionic surfactants and nonionic or amphoteric surfactants. A large number of cleaning agents and dirty components remain in the cleaning sewage of decommissioned composite insulators. Direct discharge not only pollutes the environment, but also wastes water resources.
