Problems solved by technology

In the past, during the operation of the distillation tower, because the tower wall had to be in contact with hydrogen peroxide, by analyzing the content of various ions in the hydrogen peroxide entering and leaving the tower, it was found that the Fe ions and Cr ions in the hydrogen peroxide rose, mainly due to the contact between the hydrogen peroxide and the tower wall. During the process, metal ions are precipitated from the tower and enter the hydrogen peroxide, which greatly affects the quality and quality of the hydrogen peroxide.

Abstract

The invention relates to a distillation tower used for hydrogen peroxide purification. The distillation tower comprises a tower body, a stock solution inlet, a condenser and a finished product outlet, the stock solution inlet, the condenser and the finished product outlet are respectively connected with the tower body, and the tower also comprises an automatic antioxidant loading device arranged at the top of the tower; and the automatic antioxidant loading device automatically feeds a corresponding amount of an antioxidant to the tower according to the liquid level of a stock solution when the stock solution is input through the stock solution inlet. Compared with distillation towers in the prior art, the distillation tower provided by the invention has the advantages of high quality, high yield, energy consumption reduction and the like.

Description

technical field [0001] The invention relates to hydrogen peroxide purification equipment, in particular to a distillation tower for hydrogen peroxide purification. Background technique [0002] At present, there are many industrial hydrogen peroxide concentration and purification processes, and the main tool used is a distillation tower. In the past, during the operation of the distillation tower, because the tower wall had to be in contact with hydrogen peroxide, by analyzing the content of various ions in the hydrogen peroxide entering and leaving the tower, it was found that the Fe ions and Cr ions in the hydrogen peroxide rose, mainly due to the contact between the hydrogen peroxide and the tower wall. During the process, metal ions are precipitated from the tower and enter the hydrogen peroxide, which greatly affects the quality and quality of the hydrogen peroxide. Contents of the invention [0003] The object of the present invention is to provide a high-quality, h...
