Device and method for recycling sulfuric acid

A device for recycling sulfuric acid, comprising:

• a container having an inner space;
• an inlet located at a first side of the container for introducing a liquid containing sulfuric acid and hydrogen peroxide through a pump;
• an outlet located at a second side of the container for exhausting a treated liquid from the container, wherein the first side is opposite to the second side;
• an IR lamp located in the inner space of the container for making contact with the liquid;
• a UV lamp located in the inner space of the container for making contact with the liquid;
• a bracket located in the inner space of the container for joining the IR lamp and the UV lamp;
• and
• a lid covering a top side of the container and having an air hole, wherein the air hole is connected to an exhaust device,
• wherein IR radiation emitted from the IR lamp and UV radiation emitted from the UV lamp decompose the hydrogen peroxide in the liquid to water and oxygen, the IR radiation heats the liquid to 90° C. to 130° C., and the oxygen is exhausted from the air hole.
