Embodiment Construction

[0011] The specific implementation of the seawater circulating cooling water treatment method is as follows:

[0012] The seawater circulating cooling water system uses seawater as the cooling medium, and the seawater is pressurized by the circulating water supply pump and sent to the plate heat exchanger for heat exchange. After the primary cooling is completed, it is cooled by the seawater cooling tower and recycled. . In order to ensure the normal operation of the plate heat exchanger, a self-cleaning filter is installed before the plate heat exchanger; in order to prevent corrosion, scaling, fouling and bio-adhesion of the seawater circulating cooling water system during operation, water quality stabilization and dosing facilities are provided , add seawater corrosion inhibitors, scale inhibitors and dispersants, and fungicides; the concentration ratio of the seawater circulating cooling water system is controlled at 1.3 to 1.8.

Abstract

The invention provides a circulating cooling water treatment method of sea water, pertaining to the technical field of industrial water treatment; the method is as follows: sea water is adopted as a cooling medium and pressurized by a circulating water supply pump, then transferred to a plate heat exchanger for heat exchange, later cooled by a sea water cooling tower after primary cooling is completed, and recycled. A self-cleaning strainer is arranged in front of the plate heat exchanger for guaranteeing the normal operation of the plate heat exchanger; a water quality stabilization dosing facility is arranged and a sea water corrosion inhibitor, an antiscalant dispersant and a disinfectant are added for preventing corrosion, scaling and fouling organism attachment in the operation of a circulating cooling water system of sea water; and the concentration ratio of the circulating cooling water system of sea water is controlled within the range from 1.3 to 1.8. The circulating cooling water treatment method of sea water has the advantages of saving fresh water resource, low sea water supplement, small pollutant discharge amount, being beneficial to the protection of environment and maintenance of ecological balance, low engineering investment and operation cost and the like, and is applicable to the industrial circulating cooling water in the industries of chemical engineering, electrical power, petrification, metallurgy, etc.

Description

technical field [0001] The invention belongs to the field of industrial water treatment methods, and in particular provides a seawater circulating cooling water treatment method, which is suitable for industrial circulating cooling water in chemical industry, electric power, petrochemical, metallurgy and other industries. Background technique [0002] With the rapid development of society and the rapid increase of population, the crisis of fresh water resources has attracted widespread attention from all over the world. Facing the shortage of fresh water resources in coastal cities, the development and utilization of seawater instead of fresh water as industrial water, especially as industrial cooling water, is one of the important ways to solve the crisis of fresh water resources in coastal cities and regions in my country. Seawater is used as cooling water, and there are two cooling methods, one is the seawater direct-flow cooling water treatment method, and the other is t...
