The invention relates to the field of hydrogen peroxide preparation, in particular to a high-concentration hydrogen peroxide filtration device using an anti-oxidative filter sheet material; comprising the following components: a filter body, a liquid distributor, a filter membrane, an isolation mesh, a sealing ring, a pressure relief port, pressure gauge, filtrate inlet, filtrate outlet, sight glass and sight glass valve; the device of the present invention is to remove the non-volatile matter and organic carbon contained in the high-concentration hydrogen peroxide in the circulating evaporation process, and can avoid these high viscosity The impurities adhere to the surface of the filler and the heating kettle, which brings difficulties to the production operation and heat transfer; in view of the high oxidative properties of high-concentration hydrogen peroxide, the present invention provides a filter sheet with very excellent anti-oxidation performance. The material can maintain good stability under the oxidation of high-concentration hydrogen peroxide to ensure the strength and filtration performance of the filter sheet. It is a very effective high-concentration hydrogen peroxide filtration equipment. |
