Multifunctional industrial water disposal agent and preparing method thereof

Abstract

The invention relates to the technical field of industrial recycling cooling water treatment, in particular to a multifunctional industrial water disposal agent with scale inhibition, corrosion inhibition, pre-filming, film repairing, sterilization and algae removing functions and a preparing method thereof. The multifunctional industrial water disposal agent is prepared from scale dissolving agent, scale inhibition agent, dispersing agent, fluidization agent, anticorrosive agent and biocide according to a certain mass percent. A layer of dense protective film can be formed on the surface of a device by the multifunctional industrial water disposal agent, the protective film has a self-repairing function, so that the integrity of the protective film is maintained, and then complicated operation is avoided, the number of required devices is reduced and cost is reduced. The multifunctional industrial water disposal agent can be used in the northern area with three-high water quality (high heavy metal content, high hardness and high pH value) and can also be used in the southern area with low-hardness corrosive water.

Description

technical field [0001] The invention relates to the technical field of industrial circulating cooling water treatment, in particular to a multifunctional industrial water treatment agent integrating scale inhibition, corrosion inhibition, film pre-coating, film replenishment and sterilization and algae killing and a preparation method thereof. Background technique [0002] my country is a country with severe water shortage. The total fresh water resources are 2.8 trillion cubic meters, accounting for 6% of global water resources, but the per capita water volume is only 2,300 cubic meters, which is only a quarter of the world average. Ranked 121 on the list, it is one of the 13 countries with the most water shortage per capita in the world. my country's per capita water resources are about 900 cubic meters. At the end of the 20th century, more than 400 of the more than 600 cities in the country have insufficient water supply, and 110 of them have serious water shortages. With...

Problems solved by technology

With the development of the economy, the consumption of industrial water has increased rapidly. At present, my country's industrial cooling water accounts for about 60-70% of the industrial water intake. At the same time, the contradiction between industrial water, agricultural water, and daily water is becoming increasingly acute. In this case , the water saving problem of industrial circulating water is becoming more and more important. The treatment of industrial circulating cooling water usually requires the use of scale inhibitors, dispersants, corrosion inhibitors and biocides, etc., which often leads to more equipment, troublesome operation, and high cost. Large, in order to overcome the deficiencies in the existing technology and meet the needs of the market, multi-functional water treatment agent came into being

[0003] Multi-functional water treatment agent, a series of experiments have been carried out at home and abroad, some of which have been applied in production, and there are also many domestic patent applications in this area. Due to the diversity, complexity and Variability makes the application of these patented technology products have certain limitations, and cannot meet the requirements of multifunctional water treatment agents and green environmental protection
