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
The present invention relates to a kind of bactericide and mud stripper, particularly a kind of be applicable to empty point, oxygen etc. has the novel still bactericide and mud stripper of the cooling water system of molecular sieve system.
Background technology
Empty point, the water system such as oxygen due to the impact of technique, require non-foam in whole water system, but system exists the problems such as microbial reproduction and foundry loam grow, this situation is a lot of empty point, oxygen water system insoluble problem for a long time.
Given this plant situation at present, can solve empty point, the microbial reproduction of oxygen water system and biological clay deposition problems in the urgent need to a kind of, can not cause secondary pollution, the product with the feature of environmental protection meets the market demands day by day increased simultaneously.
Summary of the invention
The present invention to provide a kind of be applicable to empty point, oxygen etc. has the novel still bactericide and mud stripper of the cooling water system of molecular sieve system, to overcome the deficiency of prior art, meets the problems such as current relevant Air separation industry microbial reproduction and foundry loam grow.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
The one sky point still bactericide and mud stripper of recirculated cooling water composed of the following components:
Vinylformic acid-(2-acrylamide-2-methyl propane sulfonic)-acrylate multipolymer 2 ~ 20%, polyquaternium 5-30%, polyepoxy sodium succinate 2 ~ 20%, polyhexamethylene guanidine sodium salt 5 ~ 30%, water 10 ~ 50%.
As limitation of the invention further, described vinylformic acid-(2-acrylamide-2-methyl propane sulfonic)-acrylate multipolymer is: vinylformic acid-(2-acrylamide-2-methyl propane sulfonic)-methyl acrylate copolymer, vinylformic acid-(2-acrylamide-2-methyl propane sulfonic)-ethyl acrylate copolymer, vinylformic acid-(2-acrylamide-2-methyl propane sulfonic)-Propylene glycol monoacrylate multipolymer, vinylformic acid-(2-acrylamide-2-methyl propane sulfonic)-hydroxyethylacrylate copolymer.Wherein the molecular formula of polyhexamethylene guanidine sodium salt is (C
7h
16n
3cl) n, n=5-20).
The present invention adopts technique scheme, kills various microorganism fast by the efficient still sterilizing ability of polyquaternium, polyhexamethylene guanidine sodium salt, thus can solve microbial reproduction and biological clay deposition problems; By poly-epoxy succinic acid, the vinylformic acid-dispersion of acrylate multipolymer, osmosis, accelerate polyquaternium, the onset time of polyhexamethylene guanidine sodium salt in biological clay and microbial film.The present invention effectively overcomes the deficiency of existing water technology, achieves empty point, the target of oxygen cooling water system energy-saving and emission-reduction Effec-tive Function.
