FOF-New non-scale anti-corrosion water treatment technology in central air-conditioning water treatment system

During the operation of the central air-conditioning water system, there will be a large amount of scale, sludge, rust and other corrosion products and algae biological slime. These dirt deposit on the surface of the heat exchanger copper tube, seriously affecting the cooling effect and service life of the central air conditioner, so It is necessary to regularly add various water treatment chemicals such as corrosion and scale inhibitors, dispersants and bactericides in the central air conditioning cooling water system and the refrigerant water system to stabilize the scaled ions in the water to prevent scaling, microorganisms and algae. Generated and controlled to protect the central air conditioning unit. This method is currently the most common method used in industrial circulating water treatment and central air conditioning water treatment. Practice has proved to be an effective and economical method. Central air-conditioning water treatment has practical significance and use value for improving central air-conditioning refrigeration effect, saving energy, restraining equipment corrosion and extending unit service life.

At present, there are some conceptual problems in the use of central air conditioning systems in China. Under normal circumstances, people think that the problems of scaling and corrosion in the central air-conditioning circulating water system are inevitable. These problems occur, as long as the equipment is cleaned regularly, without much attention. The current solution to the above problems is to periodically pickle, or to soften the circulating water in the early stage, but people have not carefully considered these methods have great hidden dangers. These hidden dangers cause the enterprise to consume a lot of manpower, material resources and financial resources every year. In the current concept, even manufacturers including central air conditioners believe that these losses are normal and inevitable.

With the development of science and technology, water treatment technology is also constantly improving. In the past, the problems brought by the old methods were normal, and in the face of new technologies, these problems can be completely eliminated. The new water treatment technology can indeed reduce costs for enterprises and bring benefits to society. It will subvert the past perceptions of central air-conditioning water treatment systems.

Below, let's talk about the so-called normal problems that exist in the central air conditioning circulating water system.

1. Hazards from periodic pickling of equipment piping.

1 increase business costs. Regular pickling requires a professional cleaning company, and does not include replacement parts and piping costs.

2. Corrosion is serious. The pickling process itself has certain corrosion to the equipment and pipelines, reducing the service life of the equipment pipeline. In addition, it cannot be completely cleaned up, and the remaining residue will cause corrosion and perforation of the pipe.

3. Waste water resources. The pickling process requires a lot of water, wastes water and increases costs. In addition, the discharged water will seriously pollute the environment.

2. Hazards from water softening treatment

1. Increase business costs. The water quality is softened, the investment is large, and the running cost is high. Moreover, water resources are wasted in the process of resin regeneration, and the generated wastewater pollutes the environment.

2. Serious corrosion

The purpose of softening water is to remove calcium and magnesium ions from the water. However, the biggest drawback of softened water is the corrosion of the equipment pipeline. The corrosion rate of softened water to carbon steel pipe is 0.3-0.5mm per year.

3. Emissions are not up to standard, polluting the environment

Through the above analysis, the disadvantages of the above two water treatment methods are quite large. Now with the development of water treatment technology, a new type of water treatment technology can completely solve these problems and eliminate the harm caused by traditional water treatment methods.

3.FOF-free scale anti-corrosion water treatment technology introduction

1. High efficiency scale inhibition

The formation of scale is usually formed by tiny crystals. The crystals are precipitated from a saturated solution. There are two steps of crystal formation and lattice growth. The growth of the crystal lattice is a slow process, only in some activated regions of the crystal nucleus. In the adsorption of precipitated ions, the crystal lattice can grow. FOF adopts ion chelation technology, which interferes with the formation from the initial stage of nucleation, makes various scale factors unable to combine, and kills the scale in the initial stage, thus achieving the effect of descaling, and the scale inhibition rate reaches 99.5. %the above.

Because FOF has advanced working principle, it has obvious scale inhibition effect on water with high hardness, high alkalinity and high salinity. The drug is very stable and the test proves that there is no attenuation at 200 degrees Celsius. This means that scale inhibition problems that many areas cannot solve in the past can now achieve the effect of scale inhibition through this technology.

2 solubility limit effect

The effective scale inhibition concentration of FOF for high hardness water usually 0.5-1 mg/L of the agent prevents a few hundred MG/L of calcium and magnesium ions from forming scale. This action allows the fof scale and corrosion inhibiting product to prevent scale formation in circulating water at very low levels.

3. Antiseptic effect

The couple contains a corrosion inhibitor in the agent, and the active group of the corrosion inhibitor is easily combined with the metal to form a chemical film, and the corrosion inhibitor can also form a precipitation film with the ions in the medium, so that the corrosion rate of the metal is slowed down. The FOF corrosion-inhibiting product is mainly formed by chemically bonding a lone pair of electrons with a metal ion to form a complex on the metal surface to form a stable and dense protective film, thereby isolating the re-contact of the corrosive medium with the metal to protect the metal. the goal of.

Fof product technical features.

The solid product can achieve true controlled micro-solubility corrosion inhibition, the effective working concentration is less than 1ppm, and it is slightly soluble in the determined water capacity.

The pH value is neutral, safe and environmentally friendly. The treated water meets the drinking water standard and can be directly consumed.

The scale inhibition effect is over 99.5%, and the scale is basically achieved.

It can effectively improve the corrosion of multiple metals.

The physicochemical properties are stable, non-corrosive, do not participate in chemical reactions, are non-flammable, and can maintain scale inhibition effect under high temperature effect.

The scale inhibition effect is not affected by the outside world, and the action time is long.

1. Protect equipment, extend life, remove rust and rust, prevent corrosion and damage of equipment, especially after equipment treatment, extend equipment life. After the corrosion inhibitor is put into use, the corrosion rate of the equipment is reduced by 90%, the small temperature difference can be less than 1 degree, and the scale inhibition rate is above 99.5%. After use, the equipment is not scaled and does not need to be descaled and cleaned.

2. Reduce accidents, improve cooling effect, sterilize algae, remove sludge, make pipelines clear, clear water, prevent scale, improve the exchange efficiency of condenser and evaporator, thus avoiding high pressure operation and overpressure shutdown. Improve the flow of chilled water, improve the cooling effect, and make the system safe and efficient

3. Save electricity, save fuel, remove scale and prevent scale formation, improve heat exchange efficiency, reduce electricity consumption and fuel consumption by 20%, and reduce water discharge and improve circulating water utilization. Generally saves more than 60% of water.

4. Save a lot of maintenance costs for customers

5. Meet environmental requirements
