Abstract

The invention discloses a biocide of marine organisms. The biocide is prepared from the following components by mass percent: 20-60% of polyquaternium, 10-60% of hyamine, and the balance of water. A preparation method of the biocide comprises the following steps: dissolving the hyamine in the water, adding the polyquaternium while stirring, and sufficiently and evenly stirring after all the polyquaternium is added to obtain the biocide of the marine organisms. According to the biocide of the marine organisms, the polyquaternium and the hyamine are compounded to use, biological slime and biomass can be effectively stripped by aid of the fast permeation effect of single-molecule hyamine, and a better biocidal effect can be achieved as the active ingredients of the hyamine can act on biological tissues more effectively; in addition, as the polyquaternium is not apt to bubble, generation of bubbles can be reduced during use, and the good biocidal effect can be kept even when the sea water quality is heavily turbid.

Description

A kind of marine growth biocide
Technical field
The present invention relates to a kind of marine growth biocide.
Background technology
In recent years, along with expanding economy, China is newly-built many power plant in coastal area, and in order to save the water resource of preciousness, what many power plant all adopted is direct cooling technology.Direct cooling technology is the cooling technology that the current whole world is comparatively popularized, with sea water directly as cooling medium, complete after once cooling through heat-exchange apparatus, directly discharge, advantages such as there is water intaking temperature is low, good cooling results, system operational management are simple, but it is subject to seawater corrosion and sea organism attachment due to equipment, often affects the properly functioning of equipment.
The harm major embodiment of sea organism attachment is in the following areas: easily adhering to substantial amounts of marine organisms on the pipeline of cooling water system and heat transmission equipment, these marine growths can affect safe operation and the work efficiency of unit in varying degrees in system;nullThe ovum of marine growth、Larva can pour in sea water in mating period,Due to these marine organisms such as blue or green shellfish、Brown shellfish、Concha Ostreae、Barnacle、Bivalves、Angle a species of small clam living in fresh water and the same hydroid etc. of similar hay,All there is stronger adhesiveness,And like gregarious,Once there be small part biology to survive in systems,When suitable water temperature and nutritious,Understand breeding of quickly growing up in systems,Form substantial amounts of biocenose assemble and live in peace in system,The production run of generating set can be caused serious potential safety hazard,Once condenser tube is by toxicity bioassay,Cooling water inflow is not enough,Recirculated water inlet pressure is caused to increase,Enter、The pressure reduction of the port of export increases,Cooling effectiveness declines,Clean reaching to a certain degree to need afterwards to carry out half side isolation,Under bad working environments,Even can cause unit outage,Marine growth also can secrete substantial amounts of biological cement while growth attachment,Corrosion pipeline equipment,Reduce the heat exchanger effectiveness of condenser;Rotary sieve and circulating water pipeline also easily gather a large amount of green snail, barnacle etc., and cleaning work amount is very big, costly.Therefore, solve the infringement that causes of sea biological pollution, be once-though cooling technology a great problem in the urgent need to address.
At present, domestic and international sea biological pollution control technology is essentially all the method adopting physical control and Chemical Control to combine.Chemical control method is broadly divided into Electrolyzed sea water chlorination (or chlorate) and directly adds chemistry biocide two kinds.
U.S.'s backman Business Name is the marine growth biocide product of Bulab6002 is composite with 2-thiocyanomethylthio benzothiazole (TCMTB) with polyhexamethylene guanidine, and wherein polyquaternary ammonium salt plays the effect of killing livestock.The shortcoming being used alone polyquaternary ammonium salt is in that owing to its molecular weight is relatively large, poor permeability, when turbidity of sea water is higher, and meeting strong adsorption silt, produce flocculation, it is impossible to be applied to marine growth tissue, do not have effect of killing livestock.
Quaternary ammonium salt is unimolecule compound, has permeability strong, and energy rapid osmotic is to cell wall, and drug action is fast.Meanwhile, quaternary ammonium salt also has that toxicity is low, wide spectrum, the performance such as efficient, and bacterium algae mud is had release effect.Its shortcoming is in that it belongs to unimolecule structure, and cationic strength is low, and absorption affinity is not enough, and marine growth is easily replaced with sea water and made medicament free, and loses effect of killing livestock, it is easy to when developing immunity to drugs and use, foam is many etc..
Compared with quaternary ammonium salt, the cationic degree of polyquaternary ammonium salt is higher, absorption affinity is higher, better effects if of therefore killing livestock, and the zest of polyquaternary ammonium salt is low, the marine growth such as shellfish, barnacle can be made to adsorb enough medicaments in automatic situation, the macromolecule chain section of polyquaternary ammonium salt also can cover marine growth tissue surface, hinders marine growth to breathe, improves effect of killing livestock, and it is not easy to foaming, foundry loam is had stronger stripping and peptizaiton.
Summary of the invention
