Embodiment 1

[0061] An environment-friendly cooling system bactericide and algicide, comprising the following components:

[0062] Hydrogen peroxide 10kg; dioctyl sodium sulfosuccinate 5kg; polyaluminum ferric chloride 0.5kg; polyhexamethyleneguanidine 11kg; attapulgite 4kg; deionized water 20kg.

[0063] The preparation method of environment-friendly cooling system bactericidal algicide is as follows:

[0064] S1. In a 200L stirred tank, stir at a speed of 200r / min at room temperature, add 10kg of deionized water while stirring, mix 10kg of hydrogen peroxide, 5kg of dioctyl sodium sulfosuccinate, polyhexaethylene Add 11 kg of methylguanidine to the stirring tank after mixing evenly, mix and stir evenly to form a pre-mixture;

[0065] S2. Add 0.5 kg of polyaluminum ferric chloride, 4 kg of attapulgite, and 10 kg of deionized water to the premixture while stirring, and mix and stir evenly to obtain an environmentally friendly cooling system bactericide and algicide.

Embodiment 2

[0067] The difference with Example 1 is: 15kg of hydrogen peroxide is added in the stirred tank; 7kg of dioctyl sodium sulfosuccinate; 1.5kg of polyaluminum ferric chloride; 14kg of polyhexamethylene guanidine; 6kg of attapulgite; 30kg of water.

Embodiment 3

[0069] The difference with Example 1 is: 20kg of hydrogen peroxide is added in the stirred tank; Dioctyl sodium sulfosuccinate 10kg; Polyaluminum ferric chloride 3kg; Polyhexamethylene guanidine 18kg; Attapulgite 9kg; Deionized water 40kg.

Abstract

The invention discloses an environment-friendly cooling system sterilizing algicide. The environment-friendly cooling system sterilizing algicide comprises the following components in parts by mass: 10-20 parts of hydrogen peroxide; 5 to 10 parts of sodium diethylhexyl sulfosuccinate; 0.5 to 3 parts of polyaluminum ferric chloride; 11 to 18 parts of polyhexamethylene guanidine; 4-9 parts of attapulgite; and 20 to 40 parts of deionized water. A preparation method of the environment-friendly cooling system sterilizing algicide comprises the following steps: S1, adding deionized water into a reaction container, uniformly mixing hydrogen peroxide, sodium diethylhexyl sulfosuccinate and polyhexamethylene guanidine, adding an obtained mixture into the reaction container, and uniformly mixing andstirring to form a pre-mixture; and S2, sequentially adding the rest components into the pre-mixture while stirring, and uniformly mixing and stirring to obtain the environment-friendly cooling system sterilizing algicide. The environment-friendly cooling system sterilizing algicide is suitable for an industrial circulating cooling water system and an air conditioner cooling water system. The method has the effect of improving the stripping capacity of the environment-friendly cooling system sterilizing algicide.

Description

technical field [0001] The invention relates to the technical field of cooling system treatment, in particular to an environment-friendly cooling system bactericide and algicide. Background technique [0002] At present, in the open circulating cooling water system, the heat of the equipment is taken away mainly by cooling water evaporation. During the cooling process, due to the contact between the cooling water and the air, the dust, microorganisms, oxygen, etc. in the atmosphere enter the cooling pipe from the cooling tower, and the microorganisms in the cooling pipe and the mucus they produce mix with the impurities in the cooling water and deposit to form biological slime. Once the biological slime is formed, it will not only reduce the cooling effect of the cooling system, but also isolate the effect of the chemical on the cooling pipeline, so that the chemical cannot play its due role in corrosion and scale inhibition. Therefore, it is very important and essential to...
