The various minerals contained in the cooling water during the use of the glass-lined condenser will form a hard scale on the pipe wall. Since the thermal conductivity of the scale is small (generally 1.5-2kcal/mh °C), the glass-lined condenser is in use. The various minerals contained in the cooling water will form a hard scale on the pipe wall. Since the thermal conductivity of the scale is small (generally 1.5-2kcal/mh °C), the heat transfer resistance increases, and the heat load qf per unit area decreases. The heat transfer efficiency of the bismuth glass condenser is lowered, resulting in a series of adverse consequences such as an increase in the condensing pressure PL, an increase in power consumption, and a decrease in the refrigeration coefficient.

In order to make the refrigeration system operate safely and economically under normal working conditions, so that the glass-lined condenser has and maintains good heat transfer capacity, it must be prevented from scaling and scale removal. According to the author's investigation and practice, prevent and remove scale. There are roughly three methods.
1. Electronic magnetic water device descaling and anti-scaling method scraper film evaporator http://
The working principle of the electronic water magnetic device is to dissolve calcium, magnesium and other salts in the cooling water flowing through the glass-lined condenser in water under positive and negative ions at normal temperature, and the cooling water flows through the magnetic water at a certain speed. In the transverse magnetic field, the dissolved calcium and magnesium ions get the induced electric energy, the charge state changes, and the electrostatic attraction between the ions is disturbed and destroyed, thus changing the crystallization condition and making the crystal structure loose, tensile and anti-stretching. The pressure capacity is reduced, and hard scale with strong adhesion cannot be formed, and the loose sludge is discharged with the flow of the cooling water. The descaling method can effectively prevent the generation of new scale, and can also remove the original scale, because after using the electronic water magnet, the ions lose the ability to scale, which loses the protection of the original scale. In addition, the magnetized cooling water has a certain amount of inductive electric energy, and at the same time, due to the difference in the expansion coefficient of the steel pipe and the scale in the glass-lined condenser, the original scale gradually cracks, and the magnetized water continuously intrudes into the crack. It destroys the adhesion of the original scale, makes it gradually loose and falls off on its own and is continuously taken away by the circulating cooling water.
The descaling method of the electronic magnetic water device is simple and easy, low in labor intensity, safe, reliable, non-toxic, and not easy to damage the pipe wall in the glass condenser, and the process and equipment are simple, and it is convenient to install, operate and manage. This descaling method is applicable to various glass-lined condensers and performs descaling and prevention of fouling without affecting the normal operation of the refrigeration system.
