[Problems to be solved by the device]

 The purpose of using the magnetic water treatment equipment is to remove scale (usually when water is used as boiler water or cooling water for coolers) and red rust (when tap water is used for a long period of time, it occurs on the inner wall of the water pipe). Control (prevention and removal). However, the above-mentioned conventional magnetic water treatment devices (1), (2) and (3) have the following drawbacks. (1) Magnetic water treatment device (1) ... (a) When the cylinder is a conductor Although it is effective for scale control, it is less effective for red rust control.

[0004]

[Means for Solving the Problems]

 In order to eliminate the above-mentioned drawbacks, the method adopted by the present invention is that one sheet of conductor sheet having a wavy or uneven cross section or a plurality of sheets stacked in a cross pattern, a honeycomb shape, etc. It is a method of arranging along the water flow.

[0005]

[Action]

FIG. 1 schematically shows a cross section of a basic magnetic water treatment device according to the present invention. The different poles of the flat magnets 1, 1 ′ face each other to form a magnetic field and a water channel, and an uneven conductor sheet 7 is arranged in this magnetic water channel 2. Water flows from the front side to the back side of the drawing. The operation of the processor shown in FIG. 1 will be described below. Positive ions 3 (H ⁺ , Ca ^2+, etc.), anions 4 (OH ⁻ , Cl ⁻ , HCO ₃ ^−, etc.), dissolved oxygen 5 (O ₂ ) etc. contained in water are perpendicular to the magnetic field along with the water flow. Flow to. Then, a Lorentz electric field is generated, and the positive ions 3 and the negative ions 4 move in directions opposite to each other, which are perpendicular to the water flow and the magnetic field. Since dissolved oxygen 5 is a paramagnetic substance, it is attracted to both electrodes, but its degree can be ignored, and it flows while colliding with the uneven conductor sheet. The region where OH ⁻ is attracted becomes alkaline, and in this region, the colloidal particles of calcium carbonate, which is the source of scale, grows into sludge particles. Sludge particles attach and remove existing scale. In this way scale control is achieved. Anions 4 that collide with the partition of the conductor discharge electrons to the partition, and the electrons are given to cations 3 and dissolved oxygen 5 that collide with the opposite side of the same partition. The dissolved oxygen O _{2 which} has received an electron becomes O ₂ ⁻ . This conversion reduces the amount of dissolved oxygen that oxidizes iron to red rust, and the produced O ₂ ⁻ reduces existing red rust to a harmless state. In this way, control of red rust is achieved.

【Example】

 (Example 1) Six flat plate magnets of 30 L x 60 W x 5 tmm were combined so that the different poles face each other at a distance of 3 mm, and they were housed in a square stainless case with an inlet / outlet pipe to assemble a magnetic water treatment device.

As described above, since the scale control ability of the magnetic water treatment device is generally established, the focus of the ability test was placed on the red rust control as follows. Iron nail rust test water tank (30x2φmm iron nail whose surface is melted with dilute nitric acid and polished with # 240 sandpaper is suspended horizontally and parallel to the water flow), circulating pump and the above magnetic water treatment device. Were sequentially connected to form a water circulation circuit. At the same time, for the blank test, a water circulation circuit consisting of an iron nail rusting test water tank and a circulation pump was also created. After circulating the water for 4 hours, the pump was stopped and the surface of the nail and its periphery were observed. Around 2 hours of circulation, red rust started to be scattered. Immediately after standing still, the white-green color material began to sink and diffuse, red rust increased on the surface, and red rust deposited on the bottom of the tank. The rusting did not differ from the blank test. Subsequent to the above experiment, an uneven stainless steel sheet of 40 Lx60 Wx3 Hmm was inserted into the 3 mm gap of the flat plate magnet of the used treatment device, and the same experiment as above was performed. The amount of red rust formed after standing still for 24 hours was about 20% of the blank test. The effect of inserting the concave and convex stainless steel sheet was remarkable. (Example 2) 12 pieces of 75φx20mm disk magnets are arranged as SNNS □ SNNS □ SNN S ... (□ is a gap) and housed in a 100φx300mm PVC cylinder with an inlet / outlet pipe, and a magnetic water treatment device is provided. Configured. The same experiment as in Example 1 was conducted using this processor. There was no difference in rusting from the blank test. Subsequent to the above experiment, a corrugated stainless steel sheet of 1000 W x 300 L x 3 Hmm was wound around the gap between the magnet row and the cylinder of the used processor with the magnet row as the core, and the same experiment as above was performed. The amount of red rust formed after standing still for 24 hours was about 5% of the blank test. The effect of inserting the corrugated stainless sheet was obvious.

[Effect of device]

 According to the present invention, the red rust control ability, which is a drawback of the conventional magnetic water treatment device, can be remarkably improved by the additional simple means of inserting a corrugated or uneven conductive sheet into the magnetic water channel. Therefore, the conventional magnetic water treatment device can be remarkably miniaturized without impairing the red rust control ability. Recently, the number of old buildings has increased, and many buildings have been plagued by red water due to red rust, and countermeasures against them are urgently needed. Under such circumstances, the effect of the present invention, which can provide a magnetic water treatment device having a remarkably improved red rust control ability with a simple configuration, is great.
