Abstract

The invention discloses a foamless sterilization remover for air separation recirculated cooling water. The above water treatment agent comprises 2-20% of acrylic acid-acrylamido-2-methylpropanesulfonic acid-acrylate multipolymer, 5-30% of polyquatemary ammonium salt, 2-20% of sodium polyepoxysuccinate, 5-30% of polyhexamethylene guanidine and 10-50% of water. The water treatment agent can solve the problems of microbe breeding and biological slime deposition of air separation and oxygen production systems in order to effectively overcome insufficiencies of existing water treatment technologies and realize the energy saving and emission reduction purposes.

Description

technical field [0001] The invention relates to a bactericidal stripping agent, in particular to a novel non-foaming bactericidal stripping agent suitable for cooling water systems with molecular sieve systems such as air separation and oxygen production. Background technique [0002] Air separation, oxygen generation and other water systems are required to be free of foam due to the influence of the process, but the system has problems such as microbial reproduction and slime growth. This situation has been difficult to solve for many air separation and oxygen generation water systems for a long time question. [0003] At present, in view of this situation, there is an urgent need for a product that can solve the problem of microbial reproduction and biological slime deposition in air separation and oxygen-making water systems, and will not cause secondary pollution, and has the characteristics of green environmental protection to meet the increasing demand. Market require...
