BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic fluid device which uses a fluid for magnetic treatment.

[0002]

BACKGROUND OF THE INVENTION It has been widely attempted to obtain various effects by magnetically treating water, fuel oil and the like.

Pipes for supplying water and hot water in buildings and the like are
During many years of use, the inner wall of the pipe is corroded and red rust is generated, and impurities in the water are deposited, causing the inner diameter of the pipe to gradually decrease, reducing the water pressure and generating so-called red water. In the end, water leakage and water cutoff will occur.

[0004] In order to prevent these problems, the method conventionally used is a method in which silica sand or the like is blown with compressed air to scrape off red rust or the like, and then a lining treatment is performed with an epoxy resin or the like, or chemical means There is a method of performing a lining process after removing red rust and the like. However, water supply pipes and hot water supply pipes are usually long and have bends, and it is difficult to completely remove red rust and the like from the long pipes having these bends and perform a uniform lining treatment. However, there is a problem that red rust is generated again from the place where the red rust remains or the place where the lining is incompletely processed. In addition, all of these had the problem that they had to be cut off for a long period of time and that it was expensive.

[0005] In recent years, construction can be carried out for a long period of time without water interruption, there is no problem with water quality, and the cost is low. The magnetic treatment method for removing red rust or the like formed on the inner wall of the pipe or preventing the generation of red rust or the deposition of impurities is being adopted by passing the treated water through the pipe.

A final academic view is given as to why the red rust on the inner wall of the pipe is removed by passing the magnetically treated water through the pipe, and the generation of red rust and the deposition of impurities are prevented. Impurities, which are not present, are contained in water by passing it through a magnetic field: electrolytes present in the form of ions, non-electrolytes present in the form of molecules, solid particles of microdispersion, dissolved gases. It is thought that this is because it undergoes magnetic and electrical effects and undergoes physical and chemical changes.

Further, in order to improve the combustion efficiency in the boiler and reduce the soot and dust, and to reduce the fuel consumption of an engine such as a diesel engine, heavy oil,
Fuel oil such as diesel has been magnetically processed.

It has not been clarified why the combustion efficiency in the boiler can be increased and the soot and dust can be reduced by magnetically treating the fuel oil, and the fuel consumption can be reduced in the engine such as diesel engine. However, it is considered that the magnetic processing of the fuel oil promotes the miniaturization of the fuel.

Various devices have been proposed as devices used for magnetically treating these water, fuel oil and the like.

The inventor of the present invention also previously found that a spacer made of a non-magnetic material was used as a magnet in a cylindrical body made of a non-magnetic material having a spiral structure made of a non-magnetic material provided on the outer periphery thereof. A magnetic treatment apparatus for water (Laid-Open Application No. 62-174520) is proposed in which water is laminated with a space provided therebetween.

The above magnetic processing apparatus can efficiently perform magnetic processing and has a high effect of magnetic processing. However, if a cylindrical body made of the above nonmagnetic material is used, which has a large number of holes, it will be further reduced. It was found that the effect can be enhanced.
