Background

With the development of economy and the improvement of the scientific and technical level in China, the central air conditioner is widely applied to places such as various companies, markets, school canteens and the like. The central air-conditioning water system of the energy station is the most important part. Energy station water system is at the operation in-process, rubbish such as some incrustation scales, rust, algae often can appear in the water system of the inside, if these rubbish is not clear away in time, through constantly accumulating, can lead to pipeline jam, deformation or even corruption, and the pipeline suffers destruction, and the refrigeration/heating effect of air conditioner also can receive the influence, and then shortens equipment life, increases power consumption, and under the serious condition, the phenomenon of high pressure trip machine still probably appears in the host computer.

According to the investigation, the scale with the thickness of 1mm can reduce the cooling/heating effect of the air conditioner by 20 to 40 percent, and the power consumption is increased by 20 to 30 percent. In the long run, this would be a considerable expenditure. Therefore, the water system is cleaned on time. Compared with the traditional physical cleaning and chemical cleaning, the system can save the cost by more than 50 percent.

The conventional methods at present are mainly divided into two main categories, physical cleaning and chemical cleaning.

Physical cleaning means that a water system is cleaned by a physical method such as water flow flushing or by means of a tool, rust, clay and the like of a pipeline are removed firstly by using a cannon dredging device and the like, and then high-pressure water is used for flushing.

The chemical cleaning is to use some chemicals, such as acid and alkali substances, in combination with a high-efficiency corrosion inhibitor to perform acid cleaning, alkali cleaning and the like, so that deposits are dissolved, and then sludge is effectively cleaned.

Both of these approaches, however, while providing some degree of cleaning of the water system, have their own drawbacks and deficiencies. The physical cleaning adopts a mechanical mode, so that the pipeline cannot be corroded, and the secondary pollution caused by waste liquid after chemical cleaning is avoided. However, it is laborious to wash and has a poor cleaning effect. Chemical cleaning can thoroughly remove dirt, but chemical substances such as acid and alkali have certain corrosivity on pipelines, the quantity is difficult to control, and in addition, waste liquid is generated after cleaning, so that secondary pollution is easily caused.
