Problems solved by technology
[0004] However, none of the above-mentioned hydrogen peroxide decomposers can withstand the aqueous solution with a mass concentration of sulfuric acid as high as 50%. Sulfuric acid will destroy enzymes and dissolve metals, resulting in the loss of effective active ingredients in the catalyst.

The invention discloses equipment and a method for removing hydrogen peroxide in sulfuric acid. The equipment comprises a supergravity device provided with a closed treatment space, wherein a rotor device is arranged in the closed treatment space from bottom to top, and is driven by a power source to generate high-speed rotation, waste sulfuric acid entering from the middle of the equipment through a liquid distributor is uniformly distributed to form suspended small liquid drops which are thrown out under the action of centrifugal force; a stator device arranged from top to bottom comprises more than one ultraviolet lamp tube so as to completely irradiate the small liquid drops which are uniformly distributed to form suspension by lamplight, oxygen generated after decomposition reaction of hydrogen peroxide is immediately extracted by an air extractor so as to avoid the situation that hydrogen peroxide is formed again after being irradiated by ultraviolet light and contacted with water, and the metal ions after acid washing are oxidized into metal oxides which can be filtered by a filtering device, so that the purity of the sulfuric acid can be effectively improved, and the aims of recycling and reusing the sulfuric acid and improving the environmental protection problem are fulfilled.
Description
technical field [0001] The invention relates to the technical field of purification, recovery and reuse of waste sulfuric acid, in particular to a device and method for removing hydrogen peroxide from sulfuric acid, wherein the waste sulfuric acid is rotated at a high speed by a supergravity device and uniformly distributed to form suspended small droplets, which can be fully obtained The oxygen produced by the hydrogen peroxide decomposition reaction is immediately extracted by the exhaust device to avoid contact with water after being irradiated by ultraviolet light to form hydrogen peroxide again, and the metal ions after pickling are oxidized into metal oxides, which can be filtered through the filter device In addition, the purity of sulfuric acid can be effectively improved in this way, so as to achieve the purpose of recycling and reusing and improving environmental protection issues. Background technique [0002] In the current wafer manufacturing process, one of the...
