Abstract
The present invention introduces a method for processing waste oil in an oil collecting box of a cooker hood. An oil cup or the oil collecting box, which aggregates waste oil of the cooker hood is designed into an electrolytic tank in which salt solution and an electrode constant temperature heating plate are arranged; the salt solution in the oil collecting box of is electrolyzed under the action of the electrode constant temperature heating plate which is communicated with direct current, and alkali solution containing NaOH is formed; the dripped waste oil and the dripped alkali solution generate the saponification reaction to generate fatty acid sodium when temperature is not less than 60 DEG C. The intracavity salt solution after energization becomes the alkali solution containing sodium hydroxide. After an upper oil drop enters lower waste oil processing chamber, the oil drop and alkali generate the saponification reaction to generate sodium salt (means soap) of higher fatty acid. Once the reaction is successful, the brown waste oil drop which drips into the lower waste oil processing chamber can become milky soap solution, and can achieve the rummy purpose that oil is used for washing oil.
