Problems solved by technology

[0002] The by-product hydrogen in the chlor-alkali industry is a by-product of the electrolysis of salt water. It is mostly a gas at atmospheric pressure. There are many impurities in the hydrogen. In addition to trace amounts of chlorine, there are also trace amounts of oxygen, nitrogen, and carbon dioxide, which are usually discharged as

Abstract

The invention provides a byproduct hydrogen purification recovery system and method in the chlorine industry. The byproduct hydrogen in the chlorine industry enters a washing tower, the solution in a water tank enters the spraying tube in the washing tower through a water pump at the same time, the hydrogen dechlorinated by the washing tower is discharged from the top of the washing tower and then enters a buffer tank, then the hydrogen buffered by the buffer tank enters a hydrogen compressor for pressurization and then enters a gas-liquid separator, after gas-liquid separation, the hydrogen enters a deaerator for removing the oxygen in the hydrogen, after deoxidization, the hydrogen enters a first adsorber for dehydration and impurity removal and then enters a gas filter, and finally after filtration, the hydrogen enters a hydrogen recovery device. The system provided by the invention simplifies the instrument and equipment and industrial processes, and saves industrial costs.

Description

technical field [0001] The invention relates to a system and method for purifying and recovering hydrogen by-product in chlor-alkali industry. Background technique [0002] The by-product hydrogen in the chlor-alkali industry is a by-product of the electrolysis of salt water. It is mostly a gas at atmospheric pressure. There are many impurities in the hydrogen. In addition to trace amounts of chlorine, there are also trace amounts of oxygen, nitrogen, and carbon dioxide, which are usually discharged as by-product hydrogen. It is easy to waste resources. The trace amount of chlorine in hydrogen is difficult to remove, and other gases such as water vapor and impurities in hydrogen need to be removed, but the existing equipment only removes certain gases or impurities separately, and the hydrogen obtained in this way is still not too pure hydrogen. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, provid...
