An adsorption tank used in hydrogen peroxide purification process

Abstract

The invention discloses an adsorption tank applied to the hydrogen peroxide purification process. The adsorption tank comprises a vertically-arranged tank body and is characterized in that a feeding port is formed in the bottom of the tank body, a discharging port is formed in the top of the tank body, multiple resin bed layers are arranged in the tank body from top to bottom, the thickness of each resin bed layer is smaller than or equal to 30 cm, and the spacing distance between every two adjacent resin bed layers is larger than or equal to 5 cm. Under segmentation of the resin bed layers, heat transfer is promoted, and the heat accumulation process is slowed; meanwhile, through the temperature and pressure monitoring measures, operating personnel can monitor the temperature and pressure change conditions of all spaces in the tower in real time and take related measures; due to the fact that the resin bed layers actually divide the tower into multiple independent spaces, and the top and the bottom of the tower are each provided with two rupture disks, the rupture disks act when the equipment pressure exceeds the limit, and therefore equipment damage can be prevented under the certain condition.

Description

technical field [0001] The invention relates to the field of purification treatment of hydrogen peroxide products by anthraquinone method, in particular to an adsorption tank used in the purification process of hydrogen peroxide. Background technique [0002] Hydrogen peroxide is one of the main basic chemical products in the world. At present, the anthraquinone hydrogen peroxide production process is its main production method. Based on this production process, a large amount of aromatic hydrocarbons and anthraquinone organic compounds will be used, and hydrogen peroxide products will also contain these substances. , as the operating time of the device increases, the content of anthraquinone organic matter will also increase, which will cause problems for subsequent use. For example, when hydrogen peroxide containing organic carbon is used for the production of cyclohexanone oxime, this part of organic matter will be brought into the In the final product caprolactam, it wil...
