Abstract

The invention discloses a hydrogen peroxide concentration apparatus, and relates to the technical field of the safety of hydrogen peroxide. The hydrogen peroxide concentration apparatus comprises a filtration device communicated to a diluent raw material inlet, an evaporation device connected to the filtration device in a cut-off manner, and a condensation pipeline respectively connected to the evaporation device, a pressure reducing device and a concentrated hydrogen peroxide chamber, wherein the position positioned in the evaporation device and close to the inlet of the condensation pipelineis provided with a heat dissipating member. According to the present invention, by arranging the filtration device, organic substances, metal ions and other impurities in the hydrogen peroxide produced by the industrial device can be removed so as to inhibit the catalytic decomposition of the liquid phase; through the pressure reducing device, the pressure reducing evaporation can be achieved soas to reduce the boiling point of the hydrogen peroxide, such that the distillation temperature can controlled within a safe range; and if the local abnormal decomposition occurs in the evaporation device, the heat dissipating member can timely disperse the decomposition heat and inhibit the occurrence of decomposition explosion.

Description

technical field [0001] The invention relates to the technical field of hydrogen peroxide safety, in particular to a hydrogen peroxide concentration device. Background technique [0002] It is widely recognized that hydrogen peroxide is an aqueous solution of hydrogen peroxide, and its extraction concentration must be controlled below about 40% during the production process, otherwise there may be serious safety risks. If high concentration hydrogen peroxide is required, additional concentration must be carried out. [0003] At present, the most commonly used concentration method is vacuum distillation of low-concentration hydrogen peroxide. Since the decomposition of hydrogen peroxide will release powerful energy, the common causes of its decomposition include external high temperature, electric arc, impact, and the catalysis of metal impurities inside hydrogen peroxide. Therefore, there may be problems of gas-phase explosion and liquid-phase catalytic decomposition during...
