Circulating cooling water biological slime stripping agent and method for stripping slime in circulating cooling water system

Abstract

The invention discloses a circulating cooling water biological slime stripping agent. Specifically, the biological slime stripping agent contains an alkylaryl sulfonate anionic surfactant, a biological surfactant and a penetrating agent. The invention also provides a method for stripping slime in a circulating cooling water system. The method includes putting the circulating cooling water biological slime stripping agent into circulating cooling water. The biological slime stripping agent provided by the invention can effectively strip the biological slime deposited on the equipment and pipeline inner walls of a circulating cooling water system. And by adopting the biodegradable and environmental friendly biological surfactant to replace parts of chemical synthesis surfactants, the dosage of chemical synthesis surfactants can be reduced, and at the same time, a good biological slime stripping effect can be achieved, and secondary pollution to the environment can be reduced.

Description

technical field [0001] The invention relates to a biological slime stripping agent and a method for stripping slime in a circulating cooling water system, in particular to an environmentally friendly biological slime that is suitable for circulating cooling water and can effectively strip the slime in a circulating cooling water system. A mud stripping agent and a method for stripping slime in a circulating cooling water system using the same. Background technique [0002] In the treatment of industrial cooling water, problems of corrosion, scaling and slime are often encountered. With the improvement of water treatment technology, most of the problems of corrosion and scale inhibition of cooling water have been better solved, but the problem of slime and bacteria and algae in the system is more prominent, especially in the case of material leakage, the slime often peels off not good. Once a large amount of microbial slime is formed, it will not only reduce the cooling eff...

AI Technical Summary

Problems solved by technology

The disadvantage is that trihydroxymethylnitromethane will slowly decompose and release formaldehyde in slightly alkaline solution, and the service life will be shortened, so it is not suitable for slightly alkaline circulating water

[0008] In order to remove the slime in the circulating cooling water system, the existing slime stripper needs to use a large amount of chemically synthesized surfactants, which will cause serious pollution to the environment. With the enhancement of human environmental protection awareness, it is urgent to develop a It can effectively strip the slime in the circulating cooling water system and is an environmentally friendly slime stripping agent
