Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic water treatment device, and particularly to a magnetic water treatment device, which is particularly suitable for use when scale occurs in devices that use water, such as boilers, cooling devices, heat exchangers, evaporators, etc. relates to a magnetic water treatment device for the purpose of preventing rust.
1. In equipment that uses water, such as boilers, cooling equipment, heat exchangers, and evaporators, scale forms and accumulates on piping, valves, and the inner walls of the equipment as the equipment is used. This scale narrows the pipes and waterways within the equipment - if left untreated, this condition not only reduces the efficiency of the equipment, but can also lead to serious consequences such as damage to the equipment.

For this reason, conventionally, when scale has adhered to a certain extent, a method has been adopted in which, for example, a chemical such as sulfuric acid is injected into the pipes and equipment to chemically remove the scale.

However, with this conventional method, in addition to the problem that scale cannot be completely removed, there is a major problem in that the chemicals damage the piping and equipment, shortening the life of the piping and equipment. Furthermore, the above-mentioned method that uses chemicals has the disadvantage that the operating efficiency of the equipment is reduced because it is necessary to stop operating the equipment during the scale removal period.

Furthermore, drinking water piping equipment cannot be used as drinking water for a certain period of time after scale removal work using chemicals, and even after a certain period of time, there are concerns that residual chemicals may have an adverse effect on the human body. ing.

In addition, in areas with hard water, water softening equipment using ion exchange resin etc. is used to soften hard water and supply water to equipment such as boilers, but scale formation cannot be avoided and the above problem has not been resolved. It has not been.

Therefore, the present invention magnetically treats water (including hot water) in equipment such as boilers, cooling equipment, heat exchangers, and elevators to prevent the formation of scale and rust in piping and equipment. The purpose of the present invention is to provide a magnetic water treatment device for the purpose.

By using the magnetic water treatment device according to the present invention, it is possible to prevent the formation of scale without shutting off soft water and hard water. In other words, even in areas with hard water, there is no need for water softening equipment, which is an important industrial effect.

Incidentally, scale occurs when fine particles existing in water and solid components dissolved in water adhere to the inner surfaces of pipes, valves, boilers, and other equipment as they are, or crystallize and adhere to them. This is deposits that have grown over time. In particular, when water is heated, dissolved solid components tend to crystallize, so scale formation is noticeable in heat exchangers, boilers, etc.

The present invention prevents scale-causing substances existing and dissolved in water from adhering to the inner surfaces of pipes, valves, boilers, etc. by passing water through a strong magnetic field. The present invention will be described in detail below with reference to the accompanying drawings.
