Problems solved by technology

That is, if a magnet with a very high magnetic field, such as a superconducting magnet, is used to form the magnet of the magnetic separation part of the magnetic floc, although the amount of magnetic substances added to the magnetic floc can be reduced, the magnet with a high magnetic field The production cost is high, especially the production cost of superconducting magnets whose magnetic field is dozens of times that of permanent magnets is very high

Embodiment 1

[0020] Hereinafter, the details of an embodiment of the present invention will be described with reference to the accompanying drawings 1 , 2 and 3 . In addition, FIG. 2 is an enlarged sectional view of the magnetic separator 36 shown in FIG. 1 , and FIG. 3 is an A-A sectional view of the aforementioned FIG. 2 .

[0021] First of all, Fig. 1 shows the overall schematic mechanism of the water filtration and purification device of the present invention. In the figure, the raw water 2 supplied from the pipeline 1 is first stored in the raw water storage tank 3. Here, the garbage with a size of several microns is removed. Raw water 2 , which is water to be treated, such as oil particles, organic matter, and microorganisms, is used to send a predetermined amount to pipe 5 again by pump 4 . At this time, from the seeding agent adjustment device 6 through the conduit 7, add magnetic powder such as ferroferric oxide and pH regulators in the above-mentioned pipeline 5, and also provide...

Embodiment 2

[0045] Fig. 5 shows another embodiment (Embodiment 2) of the present invention. The difference between this embodiment and the above-mentioned embodiment is that, especially from the comparison with the above-mentioned FIG. The connected flow path 68 allows purified treated water to flow into the pipe 43 . In addition, the treated water passed through the pipe 43 is accumulated in the purified water tank 44 of FIG. 1 , merged into the pipe 37 through the pipe 45 , and then discharged out of the system.

[0046] On the other hand, in this embodiment 2, while the sludge water 42 flowing into the magnetic separator 36 through the pipeline 35 flows in the flow path 71, its magnetic floc 19 is attracted by the magnetic force of the permanent magnet 51, and is adhered by the magnetic force. on the outer surface of the rotating body 53 . Then, the group of magnetic flocs 19 adhering to the surface of the rotating body 53 moves into the atmosphere by the rotation of the rotating bod...

Embodiment 3

[0049] 6 and 7 show another embodiment of the present invention (Embodiment 3). The difference between this embodiment and the above-mentioned first embodiment is that, especially in comparison with the above-mentioned FIG. 2 , the magnet 69 is composed of a superconducting magnet, and the length A between the ends of the magnet is further shortened. In addition, the superconducting magnet 69 includes: a vacuum container 70 for heat insulation; a heat conductor 72 with a superconductor 71 built in; a cold engine 73 for cooling the end of the heat conductor 72 in the vacuum container 70; A compressor 75 of the cold engine 73; and a pipeline 76 for recovering the medium-pressure gas adiabatically expanded by the cold engine 73 to the compressor. Moreover, the magnet 69 is fixedly supported by a support member 77 fixed on the water tank 41 .

[0050] In addition, these figures show a state where the superconductor 71 has already been magnetized by an external magnet, cooled to a...

Abstract

An apparatus for water filtration / purification which combines the function of filtrating off contaminants to be separated and the function of separating / concentrating the contaminants. This apparatus as a whole can be produced at a reduced cost. In the apparatus, the filtration function and the separation / concentration function are separately allocated. Namely, even when there are two or more filtration separators, the whole sludge water produced through these filtration separators can be recovered with one magnetic separator. Thus, the problem that an apparatus as a whole costs is eliminated. In the apparatus for water filtration / purification combining a filtration function and a magnetic separation function, which is intended to conduct water purification, solid-liquid separation, etc., the magnetic separation part can be made smaller. Thus, an apparatus for water filtration / purification can be provided which attains high purified-water quality and can be produced at a low cost.

Description

technical field [0001] The present invention relates to a water filtration and purification device and its method for the purpose of water purification and separation of solids and liquids (solid-liquid separation), and more particularly relates to a filter unit for filtering solids and other substances to be separated (removed) even in combination with A water filtration and purification device and its water filtration and purification device that can be realized without causing a significant increase in the cost of the device when the separation part that separates the separated substance that is separated and concentrated by the filtration is used to treat a large amount of water and other treated fluids. method. Background technique [0002] In the following patent document 1, the following membrane magnetic separation device has been disclosed, that is, for the purpose of water purification and solid-liquid separation, etc., for the purpose of solid-liquid separation, e...
