A coil 4 is provided outside the outer tube 1 and direct current is applied to generate a magnetic field in parallel with the center line of the outer tube 1. A variable resistance is provided on the way from an external electric source to the coil 4 to control the intensity of direct current and optimize the density of a magnetic flux applied to the fuel oil.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a magnetic field treatment device for fuel oil.

The fuel oil supplied to various fuel oil combustion devices, such as boilers, heating furnaces, drying furnaces, and internal combustion engines, is passed through a magnetic field generated by a magnet or the like in a direction perpendicular to the lines of magnetic force before combustion. This relates to a device that aims to improve the combustibility of oil itself, save energy, or reduce dust and phoneme oxides in a smoke exhaust room.

Conventional technology Conventionally, the combustibility of fuel oil is improved by installing the N and S poles of permanent magnets on both sides of the pipe through which the fuel oil flows to generate magnetic lines of force perpendicular to the direction of flow of the fuel oil. The so-called magnetic field treatment technology, which aims to save energy or reduce soot and oxides in flue gas, was developed in 1982.
Research report 27702 of the Central Research Institute of Electric Power Industry in June
5 and others have announced its effects, and examples of devices are commercially available under trade names such as Suittrol and Ariores.

However, at the stage of practical application, there have been some cases where the technology has been a success.

The reasons for this failure are: (1) The permissible range of effective magnetic flux density is narrow, and if it deviates slightly, it may have the opposite effect, but it is difficult to deal with such cases when using permanent magnets. Yes, (2) It is easy for a positional shift to occur between one magnetic pole and the fuel oil pipe due to pipe vibration, etc., which tends to cause a disturbance in the magnetic flux distribution, (3) The time for the fuel oil to pass through the magnetic field is too short. Problems to be Solved by the Invention The present invention solves the above points and provides a reliable method for fuel oil suitable for each case. The purpose is to perform magnetic field treatment.

Measures to solve the problem (a) A ferromagnetic partition (3) is provided in a spiral shape between the outer cylinder (1) and the inner cylinder (2), and the fuel oil is installed outside the pump. Forced to pass through in a spiral shape by pressure (b) A coil (4) is provided outside the outer cylinder (1) and a direct current is passed through it to generate a magnetic field (0e-) To obtain the optimum magnetic flux density In addition, the strength of the direct current can be adjusted using an external variable resistor.

The present invention is a fuel oil magnetic field treatment device having the above configuration.

Function The function of this device will be explained below based on Figure 6. When a current is passed through the coil (4), lines of magnetic force as shown by the broken line appear, and the magnetic flux density is proportional to the number of turns of the coil (4). It is proportional to the product of current strength. As a result, both sides of the partition (3) made of a ferromagnetic material, such as an iron plate, are magnetized to N and S poles, respectively, so that they continuously sandwich the oil passage.

Now, due to the pressure from an external pump, etc., the lower right oil inlet (5)
The oil that entered from the partition (3), the outer cylinder (1), and the inner cylinder (2)
), the oil travels in a perpendicular direction through the lines of magnetic force generated by the wall of the magnetized partition (3) until it exits from the first oil outlet (6). It's going to happen. As a result, the fuel oil that has been continuously influenced by the magnetic field comes out with improved combustibility.

The optimum magnetic flux density, which differs in each case depending on the type of fuel oil, the type of combustion equipment, the location of the magnetic field processing equipment, etc., can be determined by adjusting the external variable resistance.
It can be selected at the installation site by adjusting the amount of current flowing through it.

Example The explanation will be given below based on FIG.

(a) Outer cylinder made of non-magnetic or weakly magnetic material (1
), and a plate-shaped partition (3) made of ferromagnetic material is spirally arranged between the outer cylinder (1) and the inner cylinder (2). End plates (7) attached to both ends of the outer cylinder (1) and inner cylinder (2) forming oil passages,
8) is provided with an oil inlet (5) and an oil outlet (6), and the oil is passed through in a spiral manner by the pressure of an external oil pump, etc.
・9 A coil (4) is provided on the outside of the outer cylinder (1) and a direct current is passed through it to generate a magnetic field parallel to the center line of the outer cylinder (1).

(d) A variable resistor is provided midway from the external power source to the coil (4) to adjust the strength of the DC current to optimally adjust the magnetic flux density applied to the fuel oil. 0 shows an example of the installation location of the fuel oil magnetic field processing device 0 This is an example where the device is installed between an oil pump and a combustion burner 0 In addition, as another embodiment of the present invention, various conditions are standardized,
For small combustion devices to be mass-produced, as shown in FIG. 2, a permanent magnet (45) that provides an experimentally determined optimum magnetic flux density may be installed in place of the coil (4).
