Problems solved by technology

However, there are many serious problems in the application of chlorine gas sterilization, first of all, safety issues. Chlorine gas has a strong irritating odor and strong corrosiveness, is highly toxic, and is easy to leak. Once chlorine gas leaks, it will cause great harm to the surrounding environment and personnel. Due to the high toxicity of chlorine gas, it will have a huge ecological impact on microorganisms in the sea; secondly, the maintenance of equipment is large, and there must be at least two persons on duty for each shift of chlorine addition equipment
In addition, due to the strong corrosiveness of chlorine gas, the maintenance cost of chlorine addition equipment is very high; finally, chlorine gas is added to the circulating water for sterilization, which increases the corrosion tendency of circulating water and accelerates the corrosion of metal parts of the system
The use of sodium hypochlorite will increase the cost

Embodiment 1

[0019] Select raw materials by weight percentage

[0020]

[0021] Specific production methods:

[0022] Add 20% of deionized water, 5% of ethanol, 15% of ethylene glycol, and 15% of dodecylguanidine acetate into the reactor, keep the temperature at 25 to 35°C, stir for 60 minutes, and then add the didodecane. An aqueous solution of 15% dimethyl ammonium chloride and 30% deionized water was added to the reaction kettle by a metering pump, the addition time was 20 to 40 minutes, and the product was obtained by continuing to stir for 30 minutes.

Embodiment 2

[0024] Select raw materials by weight percentage

[0025]

[0026] Specific production methods:

[0027] Add 25% of deionized water, 30% of isopropanol, and 15% of dodecylguanidine hydrochloride into the reactor, keep the temperature at 25-35°C, stir for 60 minutes, and then add dodecyldimethylbenzyl The aqueous solution of 10% ammonium chloride and 20% deionized water was added to the reaction kettle with a metering pump, the addition time was 20-40 minutes, and the stirring was continued for 30 minutes.

Abstract

The invention provides a sea mollusc fungicide. The sea mollusc fungicide is compounded by deionized water, alcohols, guanidines and quaternary ammonium salts, wherein the mass ratio of the deionized water to the alcohols to the guanidines to the quaternary ammonium salts is (40-60):(20-40):(1-15):(1-15). The invention simultaneously provides a production method of the sea mollusc fungicide. The sea mollusc fungicide is a special fungicide for molluscs in a cooling water system, and is applicable to treatment of the molluscs such as green shells, brown shells, barnacles and hydroids. The fungicide has little effect on various fishes and shrimps, and is free of corrosion on equipment, simple in dosing equipment, small in maintenance amount, readily biodegradable and small in damage to the environment.

Description

technical field [0001] The invention relates to a bactericide, in particular to a special bactericide for mollusks in a cooling system. Background technique [0002] my country is a country with water shortages, and its per capita freshwater resources only rank 105th in the world. At present, most open coastal cities are short of water to varying degrees, and it has become a consensus to use seawater instead of freshwater for industrial cooling, which can save a lot of freshwater resources, promote social and economic development, and help protect the environment and maintain ecological balance. [0003] At present, the electric power, petroleum, chemical, steel and other industries in coastal cities all use seawater as circulating cooling water when conditions permit. But in seawater circulating water or once-through seawater cooling systems, mollusk contamination and reproduction are the biggest problems. Large numbers of shellfish (such as mussels, also known as sea red...
