Embodiment 1

[0017] in such as figure 1 As shown in the cooling tower, the FRP cooling tower is filled with fillers, and the outer wall is wound with an insulating coil, and the coil is connected to the frequency converter, which is connected to the 220V, 50 Hz mains. Through the function of the frequency converter, the insulating coil obtains The predetermined voltage is 220V, the predetermined current is 0.5AM alternating current, thereby generating an alternating oscillating magnetic field, the strength of the alternating oscillating magnetic field is 10H, and the magnetic field acts on the water flow in the cooling tower, causing the water molecules in the cooling tower to resonate. The water molecular clusters associated with hydrogen bonds become individual polar water molecules, which improves the activation of water. These tiny water molecules can penetrate, surround, dissolve, and remove the old scale in the system, making the Ca in the water 2+ , Mg 2+ and CO 3 2- Collide with...

Embodiment 2

[0020] According to the conditions and steps described in Example 1, the material of the cooling tower is stainless steel. During the processing of the cooling tower, an insulating coil is wound in the wall of the cooling tower. The insulating coil obtains an alternating current with a predetermined voltage of 220V and a predetermined current of 1AM, thereby generating Alternating oscillating magnetic field, the strength of the alternating oscillating magnetic field is 50H, and the cooling tower has operated stably and efficiently for 1.5 years without adding antiscalants.

Abstract

The invention relates to a method for electromagnetism scale inhibition of a cooling tower, for mainly solving the problems that in the prior art, the descaling cost of the cooling tower is high. The invention solves the problem well by adopting an electromagnetism scale inhibition method, namely, wounding insulating coils on an outer wall or an inner wall of a container or a pipeline through which a fluid passes, connecting the coils with a frequency converter, supplying alternating current with preset voltage and preset current to the insulating coils through the action of the frequency converter, generating an alternating oscillation magnetic field, and acting the magnetic field on the fluid inside the container or the pipeline so as to achieve a descaling effect. Therefore, the method can be applied to descaling of the cooling tower.

Description

technical field [0001] The invention relates to an electromagnetic anti-scaling method. technical background [0002] The waste heat generated in industrial production or refrigeration process is generally guided away by cooling water. The function of the cooling tower is to exchange heat between the cooling water carrying the waste heat and the air in the tower, so that the waste heat is transferred to the air and diffused into the atmosphere. Cooling tower application range: mainly used in air conditioning cooling system, refrigeration series, injection molding, tanning, foaming, power generation, steam turbine, aluminum profile processing, air compressor, industrial water cooling and other fields, the most widely used are air conditioning cooling, freezing, Plastic chemical industry. If the cooling tower runs for a long time, the surface of the filler and the inner wall of the cooling tower will be scaled, including carbonate scale and biofouling, which will block the a...
