Corrosion and scale inhibition sterilizing agent for circulating cooling water under high concentration multiple

Abstract

The invention discloses a scale-inhibiting, corrosion-inhibiting and fungicide for circulating cooling water under high concentration ratio, wherein the weight percentage of each component is: 5-15% of alkaline oxide, 30-40% of silicate, boric acid Salt 30-40%, molybdate 0-10% and metal oxide 5-10%.

Description

technical field [0001] The invention relates to water treatment technology in the chemical field, in particular to a scale and corrosion inhibitor and fungicide for circulating cooling water under high concentration ratio. Background technique [0002] As the country and society attach importance to environmental protection, the effective management and efficient use of water resources has become particularly important for industrial enterprises. In urban water supply, industrial enterprises account for 50-80% of water consumption, while 80% of industrial water is used for circulating cooling water. In order to respond to the call for energy saving and emission reduction, industrial enterprises often reduce the supplementary water volume of the circulating water system in actual production, so as to control the industrial fresh water consumption of the whole plant. However, the reduction in water replenishment means that the concentration ratio of circulating cooling wate...

Problems solved by technology

CaCO 3 The heat conduction system of scale is only about 1 / 100 of that of steel. Once scale is formed on the surface of the heat exchanger, it will seriously affect the heat exchange effect of the system, resulting in a decline in product quality and serious production accidents.
