Phosphorus-free corrosion and scale inhibition integrated agent for treating circulating cooling water and preparation method of phosphorus-free corrosion and scale inhibition integrated agent

Abstract

The invention discloses a phosphorus-free corrosion and scale inhibition integrated agent for treating circulating cooling water and a preparation method, the phosphorus-free corrosion and scale inhibition integrated agent comprises the following raw materials: 15-20% of sodium polyepoxysuccinate, 20-30% of hydrolyzed polymaleic acid, 10-20% of 2-acrylamido-2-methylpropanesulfonic acid, 10-20% of zinc sulfate and 10-20% of deionized water. The proportion of the 2-acrylamido-2-methylpropanesulfonic acid is 20%-30%, the proportion of the zinc sulfate is 5%-10%, and the proportion of the deionized water is 5%-20%. According to the phosphorus-free corrosion and scale inhibition integrated agent for treating the circulating cooling water and the preparation method, the phosphorus-free corrosion and scale inhibition integrated agent has a corrosion inhibition function and a scale inhibition function, compared with respective addition of a corrosion inhibitor and a scale inhibitor, the dosage is small, the corrosion and scale inhibition effect is better, the water treatment cost is low, environmental protection and no phosphorus are achieved, treated circulating water sewage meets the sewage discharge comprehensive standard, and the phosphorus-free corrosion and scale inhibition integrated agent is suitable for industrial production. The catalyst is stable at high temperature, has certain chlorine resistance and oxidation resistance, and can be applied to industrial circulating water sites.

Description

technical field [0001] The invention relates to the field of preparation of a phosphorus-free corrosion and scale inhibitor, in particular to a phosphorus-free corrosion and scale inhibitor for treating circulating cooling water and a preparation method thereof. Background technique [0002] Phosphorus-free corrosion and scale inhibitor is a reagent for treating circulating cooling water. Phosphorus is an element for the reproduction of bacteria and algae. Phosphorus-containing wastewater is discharged into the natural environment along with the sewage system during the circulation process, which leads to the deterioration of the natural environment and causes biological damage. Death and secondary pollution of the ecological environment, so it is necessary to replace it with low-phosphorus, phosphorus-free, biodegradable and environmentally friendly water treatment agents. The process requirements are also getting higher and higher. [0003] The existing phosphorus-free co...

AI Technical Summary

Problems solved by technology

[0003] The existing phosphorus-free corrosion and scale inhibitors have certain disadvantages in use. During the recycling process of industrial cooling water, there will be different degrees of inorganic salt deposition, corrosion and bacteria and algae growth, which will cause the efficiency of heat exchange equipment. Serious consequences such as decline, blockage, corrosion and perforation have brought great hidden dangers to industrial production, which is not conducive to people's use. In addition, because phosphorus is an element for the reproduction of bacteria and algae, phosphorus-containing wastewater is discharged with the sewage system during the circulation process. Into the natural environment, leading to the deterioration of the natural environment, brought certain adverse effects on people's use process, for this reason, we propose a non-phosphorus corrosion and scale inhibitor for the treatment of circulating cooling water and its preparation method
