Abstract

The invention discloses a hydrogen peroxide concentration device, which relates to the technical field of hydrogen peroxide safety. The hydrogen peroxide concentration device includes a filter device communicated with the inlet of the raw material, an evaporation device connected with the filter device in a cut-off manner, and a condensation pipeline connected with the evaporation device, the decompression device, and the concentrated hydrogen peroxide chamber respectively. A heat-dissipating component is provided near the inlet of the condensing pipe in the evaporation device. Impurities such as organic matter and metal ions in hydrogen peroxide produced by industrial devices can be removed by the set filter device, thereby inhibiting liquid-phase catalytic decomposition. Through the action of the decompression device, decompression evaporation can be realized, the boiling point of hydrogen peroxide is lowered, and the distillation temperature is controlled within a safe range. If local abnormal decomposition occurs in the evaporation device, the heat dissipation component can disperse the decomposition heat in time and suppress 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...
