Description
Technical field
The present invention relates to a kind of de-oiling composite detergent for adsorbent reactivation and uses thereof, be mainly used in the effective regeneration of transformer oil purifying treatment sorbent material.
Background technology
Along with country, enhancing and the attention of enterprise to conservation of resources consciousness; the research of the physicochemical property of people to oil for electric power; to useless oil handling; the consequence that the wasting of resources that it is caused produces; there is more further understanding, impelled country, enterprise formulate and have put into effect multiple about oil for electric power recycling management method and regulation.The transformer oil carrying out with Xiaogan Heng Yuan Utilities Electric Co. is regenerated as example, when processing the transformer of a 220KV, the about 50 tons of left and right of transformer oil, according to the maximum usage ratio of sorbent material, need 5 tons, sorbent material, 34000 yuan of production costs, add 30000 yuan of left and right of the expenses such as artificial maintenance, the transformer oil total price of a 220KV of adsorption treatment needs 70,000 yuan of left and right.But change the transformer oil of a 220KV, and by 10,000 yuan/ton of the market reference price oil prices of 2012, the total price of changing oil obtains 500,000 yuan of left and right, and adsorption treatment transformer oil has been saved approximately more than 40 ten thousand yuan than changing transformer oil, has considerable economic benefit.
The XDK series oil for electric power regeneration special utility high-efficiency adsorbent of Heng Yuan company research and development is the sci-tech products that have autonomous property right, through application for many years, obtained good achievement, but the improper processing of the sorbent material after oil treatment engineering can bring sizable environment and processing cost, to this, we are through exploration for many years, constantly improve the reclaiming process of sorbent material, the de-oiling composite detergent of development of new is for the regeneration of sorbent material, to realize effective recycling of resource when reducing sorbent material application cost.
Summary of the invention
In view of the needs of sorbent material highly efficient regeneration and considering of Environmental costs, the invention provides a kind of de-oiling composite detergent for adsorbent reactivation and uses thereof, gained washing composition can be used in the effective regeneration of transformer oil purifying treatment sorbent material, effectively shorten the required time of regenerative process, reduce the discharge of dusty gas in regenerative process, the sorbent material after experimental study shows regeneration falls dielectric loss and sweetening power is all slightly improved than novel sorbents simultaneously.
Technical scheme provided by the invention is: a kind of detergent composition, comprising: (1)
The anion surfactant of 6wt%-10 wt%; (2) ethoxylated alkyl ether of 3wt%-8wt%
