Description
Technical field
The present invention relates to antibacterial technical field, specially one kind are for the sterilization of industrial circulating cooling water system high efficiency composition
Agent.
Background technology
Industrial circulating cooling water system is using water as cooling medium, and a kind of cooling water system recycling, mainly
It is made up of cooling device, water pump and pipeline, cold water flows through the production equipment needing cooling(Often claim heat transmission equipment, such as heat exchanger, cold
Condenser, reactor)Afterwards, temperature rises, if discharged at once, cold water is only used once(Claim once-through cooling water system), make intensification cold
Then water temperature returns fall to current supercooling equipment, and available pumped back production equipment reuses, and the consumption of cold water substantially reduces, Chang Kejie
About more than 95%, cooling water accounts for the 70% about of industrial water consumption, and therefore, recirculating cooling water system has played a large amount of water for industrial use of saving
Effect.
Antibacterial usually can be used in present industrial circulating cooling water system, antibacterial is also known as biocide, sterilizing
Algae agent or microbicide etc., typically refer to efficiently control or kill microbial bacterial in water system, funguses and
The chemicals of algae.But it is not applied for different water quality more present antibacterial, have certain when industrially applying
Corrosivity, when putting in liquid, dissolubility is poor, and compounds and the effect of creating antagonism because each component is unsuitable, with it
Its antibacterial compatibility is also poor, leads to effect to reduce or the phenomenon of forfeiture happens occasionally, the effect of impact sterilization.
Content of the invention
It is an object of the invention to provide a kind of be used for industrial circulating cooling water system high efficiency composition antibacterial, on solving
State proposition in background technology more and be not applied for different water quality, when industrially applying, there are certain corrosivity, put into
During in liquid, dissolubility is poor, and compounds and the effect of creating antagonism because each component is unsuitable, joins with other antibacterial
5 property are also poor, lead to effect to reduce or the phenomenon of forfeiture happens occasionally, the problem of the effect of impact sterilization.
For achieving the above object, the present invention provides following technical scheme:A kind of efficient for industrial circulating cooling water system
Compound disinfectant, including the raw material of following parts by weight proportioning:Isothiazolinone derivatives 8-10 part, smell nitre alcohol 6-8 part and third
