Scale and corrosion inhibitor for air conditioner cooling water treatment, preparation method of scale and corrosion inhibitor and treatment method of air conditioner cooling water

Abstract

The invention provides a scale and corrosion inhibitor for air conditioner cooling water treatment near zero discharge and a treatment method of the air conditioner cooling water near zero discharge. Raw materials of the scale and corrosion inhibitor comprise the following ingredients in parts by mass: 10 to 15 parts of water slag regulators, 18 to 23 parts of organic amine, 16 to 32 parts of dispersing agents and 0.8 to 3.0 parts of copper corrosion inhibitors. The raw materials of the scale and corrosion inhibitor comprise the organic amine, the dispersing agents and the copper corrosion inhibitors; the raw materials are specially proportioned; the near zero discharge scale and corrosion inhibitor has a good scale inhibition effect and high anti-corrosion performance; the concentration times is improved to more than 7 times; when the scale and corrosion inhibitor is used for treating the air conditioner cooling water, the sewage discharging quantity can be greatly reduced, even no pollution is discharged, and the near zero emission is reached, so that the good water-saving effect is achieved; the water is well saved. The scale and corrosion inhibitor has the advantages that the use is convenient; the operation is simple; only the pH and the electricity conductivity need to be monitored and controlled; the site operation control index is greatly simplified, so that the operation maintenance workload is reduced.

Description

technical field [0001] The invention relates to the technical field of industrial circulating cooling water treatment, in particular to a scale and corrosion inhibitor for air-conditioning cooling water treatment and a treatment method for air-conditioning cooling water. Background technique [0002] Water conservation is the requirement of the times and the need to protect water resources. In the treatment of industrial circulating cooling water, how to increase the concentration factor has always been a topic worthy of continuous research. The higher the concentration multiple, the better the water-saving effect, but if the concentration multiple is high, the problems of scaling and corrosion will be particularly prominent. The traditional method uses sewage discharge as the main method to reduce the hardness, alkalinity and electrical conductivity of the system, but this method has a limited increase in concentration, especially for water with high hardness. In addition...

Problems solved by technology

The traditional method uses sewage discharge as the main method to reduce the hardness, alkalinity and conductivity of the system, but this method has a limited increase in concentration, especially for water with high hardness

In addition, the current system generally adopts the method of adding acid to reduce the alkalinity to increase the concentration multiple. Although this method can increase the concentration multiple to 4 to 5 times, it consumes a large amount of acid, which is dangerous and easy to cause corrosion side effects.
