A biological antifouling agent

Abstract

The invention discloses a biological antifouling agent, which is composed of the following components by weight percentage: 0-50% of alkylamine, 3-10% of emulsifier and the balance of water. Alkylamines are viscous liquids to white solids with poor solubility in water and are difficult to be directly applied to seawater systems. In the invention, the alkylamine is made into an emulsion system, which can be automatically dispersed in seawater, and the special dispersibility can effectively disperse the biological slime in the system, so as to ensure the cleanliness of the titanium tube of the condenser and the normal operation of the equipment. The invention utilizes the affinity between organic amines and metals to form a smooth protective film on the inner wall surfaces of metals and concrete to slow down metal corrosion and drive away marine organisms, preventing the adsorption and fixation of marine organisms in the system.

Description

technical field [0001] The invention relates to an industrial water treatment agent, in particular to a biological antifouling agent. Background technique [0002] In order to adapt to the country's economic development, my country has built a large number of thermal power plants in coastal areas. These coastal power plants usually use a once-through seawater cooling system, that is, a large amount of seawater flows through the condenser and is directly discharged back to the ocean. A large number of marine organisms and their eggs or larvae partially attach to the system when they pass through the system. After rapid growth and reproduction, a large number of biological populations gather and live in the system, causing serious safety hazards to the production and operation of the generating set. [0003] In order to solve the problem of a large number of marine organisms gathering and multiplying in the circulating water system, the method of adding biocide is generally ad...

AI Technical Summary

Problems solved by technology

[0004] Due to the large amount of seawater taken by the power plant, in order to ensure a good biocidal effect, it is necessary to add a large amount of marine biocide, especially in the intermittent dosing method, it is necessary to add the agent with a biocidal concentration above the effective biocidal concentration within the effective time, not only the biocide dosage Large, high cost, and a lot of chemicals have been discharged from the system before they can function, causing waste and serious pollution to the sea area around the power plant
