Method of producing circulating water system without scale source

Abstract

This invention relates to a process method for dirtless source circulation water system, which spreads coats without Ca and Mg elements on all floors, raceways, cement pipelines contacted with circulation water, all containers, installation surfaces processing and storing the water or covers isolation membranes without Ca and Mg elements to separate circulation water from cement condensates, bricks and stones containing Mg and Ca completely and cuts off supplement sources of new Ca2+ and Mg2+ ions of circulation water.

Description

technical field [0001] The invention relates to a water treatment method, in particular to a method for blocking the scaling source of circulating water used in a circulating water system. Background technique [0002] In order to save water resources, the recycling water utilization of chemical industry, metallurgy, petroleum, electric power and other industrial enterprises in the country has reached more than 80%. In the circulating water system, water is generally sprayed from the nozzle of the water spray pipe and sprayed onto the workpiece or machine. After the circulating water falls to the ground, it first flows into the ditch or the cement pipe, and then goes through the swirl pool, advection pool and other facilities to remove impurities, and finally cools and filters in the cooling pool (tower) before returning to the water spray pipe. [0003] There are two defects in the existing circulating water system: one is to use a large amount of scale cleaning and anti-s...

Problems solved by technology

[0003] There are two defects in the existing circulating water system: one is to use a large amount of scale cleaning and anti-scaling and corrosion inhibitors to prevent or alleviate the scaling problem of circulating water, which consumes a lot of money; Pipeline and nozzle blockage accidents often forced to stop production for maintenance, seriously affecting production and economic benefits

[0005] The crux of the problem is that the surface of the ground, drains, cement pipes, treatment facilities and storage pools in contact with circulating water is made of cement solidification, bricks, stones and other materials, all of which contain calcium and magnesium elements, which continuously provide Ca to the circulating water. 2+ , Mg 2+ ions, while the air continuously supplies CO to the circulating water 2 , forming CO 3 2- Anions, so the circulating water will continue to scale, which will eventually cause nozzle blockage accidents
