Description

The present invention relates to an antifouling method and an antifouling device for circulating water in a facility using the circulating water and a route through which the circulating water is passed.

Conventionally, in facilities using circulating water, for example, cooling towers, scales are sometimes formed by depositing lime or dirt contained in the circulating water inside the piping through which the circulating water is passed. When a scale is formed inside the pipe, circulation of the circulating water is hindered, and heat exchange efficiency may be reduced.
In addition, since circulating water is cooled by contact with the outside air, it takes in contaminants in the atmosphere, so that slime and biofilms are formed by the propagation of microorganisms such as algae inside the pipe, and it is represented by Legionella bacteria. Bacteria may propagate.
Slime and biofilm inhibit the circulation of circulating water, cause a decrease in heat exchange efficiency, and may corrode piping. Legionella may cause pneumonia and tuberculosis.
Thus, in facilities that use circulating water, how to prevent contamination of the facilities such as circulating water and piping (hereinafter referred to as antifouling) is an important issue.
In order to solve this problem, for example, in Patent Document 1, a supply port of a hot water supply pipe connected to a water-cooled air-conditioning cooler is positioned above the filler of the cooling tower, and the supply port of the hot water supply pipe and the filling are filled Before installing a container with a cooling water outflow hole containing tourmaline-containing ceramic particles between the material and spraying the cooling water discharged from the supply port of the hot water supply pipe into the container and dropping it into the filler An antifouling technique for purifying cooling water using the negative ion effect by passing between tourmaline-containing ceramic particles is disclosed.

[First Embodiment]
The antifouling method and antifouling device according to the first embodiment of the present invention will be described with reference to the drawings, taking as an example the case of use in a cooling tower.
FIG. 1 is an explanatory diagram of the antifouling device of the first embodiment. FIG. 1A is a plan view of the antifouling device as viewed from above, and FIG. 1B is a side view of the antifouling device as viewed from direction A in FIG. FIG. 2 is a longitudinal cross-sectional explanatory view of a cooling tower provided with an antifouling device.
In each figure, for the sake of explanation, a part is enlarged and a part is omitted.

As shown in FIGS. 1 (A) and 1 (B), the antifouling apparatus 10 includes a tourmaline carrier 11 having a tourmaline supported on the surface, a storage container 12 for storing the tourmaline support 11, and the storage container 12. The frame member 13 is arranged by being laminated at a predetermined interval.

The tourmaline carrier 11 is made of ceramic spheres having a surface layer containing tourmaline, and has a diameter of 5 to 10 mm, for example.
Here, the tourmaline carrier 11 only needs to have tourmaline on the surface. For example, the tourmaline carrier 11 may be formed as a bulk body with tourmaline ore, or mixed with a tourmaline powder and a ceramic powder such as alumina and sintered. May be formed.
The magnitude | size of the tourmaline carrier 11 can be arbitrarily set according to the magnitude | size of the water flow hole 12c of the storage container 12 mentioned later, contact efficiency with circulating water, etc.

The container 12 is a container that accommodates the tourmaline carrier 11 and allows circulating water to pass through, and is, for example, a flat rectangular parallelepiped having a width of 280 mm, a depth of 260 mm, and a thickness of 65 mm by a stainless steel wire mesh. It is formed into a shape.
The tourmaline carrier 11 is accommodated in the accommodating portion 12b from the lid portion 12a on the upper surface of the accommodating container 12. The lid portion 12a is fixed to the housing portion 12b by a fastener such as a hook (not shown).
The mesh portion of the wire mesh becomes a water passage hole 12c through which the circulating water flows into the storage container 12, and is formed in such a size that the tourmaline carrier 11 does not fall from the storage container 12.
The container 12 only needs to have good water permeability and be able to hold the tourmaline carrier 11 without passing through the water passage holes 12c. For example, a storage container in which a large number of water passage holes 12c are formed on the plate surface of a box-shaped container can be used.

The frame member 13 is a member for arranging the storage container 12 at a predetermined interval while maintaining water permeability to the storage container 12 of the circulating water.
The frame member 13 is composed of a columnar member so as not to inhibit the flow of circulating water when viewed from the top. The frame member 13 is formed in a U-shape in which one side of the cross section is opened, and mounting portions 13a on which the receiving container 12 is mounted are formed side by side at substantially equal intervals in the height direction. In the following description, the U-shaped opening direction is referred to as “front”, and the direction opposite to the opening direction is referred to as “rear”.
The container 12 is inserted into the frame member 13 from the front, and is placed on the placement portion 13a at a predetermined interval. In the present embodiment, the three storage containers 12 are arranged substantially in parallel with gaps provided at intervals of 50 mm.
In this manner, about 3 kg of tourmaline carrier 11 is accommodated in the three accommodating containers 12. Here, the amount of the tourmaline carrier 11 housed in the housing container 12 is an amount that can swing inside the housing container 12.

The frame member 13 can adopt various shapes as long as the water permeability is high and the flow of the circulating water is not hindered. For example, you may form with the plate-shaped member provided with many water flow holes.
Further, as the mounting portion 13a, various shapes such as protrusions provided at positions corresponding to the four corners of the storage container 12 and rail-shaped members or net-like members disposed narrower than the width of the storage container 12 may be adopted. it can.

Next, a case where the antifouling method using the antifouling device 10 is applied to antifouling such as piping of a cooling tower that cools circulating water by vaporization heat will be described as an example. Since the cooling tower has many opportunities for the circulating water to come into contact with the outside air and is easily contaminated, the antifouling method of the present invention can be suitably used.

As shown in FIG. 2, the cooling tower 20 is provided with a filler 21 having a filler formed by winding a filler having water permeability, for example, a corrugated resin sheet. A louver 22 for inhaling outside air is provided on the side wall of the packed bed 21.

Above the packed bed 21, a watering tank 23 for spraying circulating water is provided above the packed bed 21. An exhaust fan 24 that exhausts the air in the cooling tower 20 upward is provided above the sprinkling tank 23. A circulating water tank 25 that stores the circulating water W that has flowed down through the packed bed 21 is provided below the packed bed 21.

A plurality of antifouling devices 10 are arranged at the bottom of the circulating water tank 25 in a state of being immersed in the stored circulating water W.
The number of the antifouling devices 10 arranged in the circulating water tank 25 can be arbitrarily set according to the amount of circulating water W, the flow velocity, and the like. For example, in the medium-sized cooling tower 20, 10 antifouling devices 10 each accommodating 3 kg of tourmaline carrier 11 are installed inside the circulating water tank 25.

The circulating water tank 25 is connected to a discharge pipe 26 for supplying the stored circulating water W to a heat exchanger 28 such as a building air conditioner. The heat exchanger 28 is supplied with the heat-exchanged circulating water W. A supply pipe 27 for supplying water to the watering tank 23 is connected. In the present embodiment, the discharge pipe 26 includes a strainer 29 at the tip, and is formed at an end near the bottom of the circulating water tank 25. Since the circulating water W stored in the circulating water tank 25 is discharged from the discharge pipe 26, a water flow F (water flow toward the lower right in the drawing) toward the discharge pipe 26 is formed.
Here, it is preferable to arrange the antifouling device 10 at a position where the flow rate of the circulating water W is fast, such as in the vicinity of the discharge pipe 26.
Moreover, it is preferable to arrange | position the antifouling apparatus 10 so that the front of the frame member 13 may face the upstream of a water flow so that the storage container 12 may not move in the frame member 13 by a water flow.

The cooling tower 20 operates as follows to cool the circulating water W.
The circulating water W stored in the circulating water tank 25 is sent to a heat exchanger 28 such as a building air conditioner via a discharge pipe 26, and heat is exchanged by the heat exchanger 28. The circulated water W subjected to heat exchange is sent to the watering tank 23 via the supply pipe 27 and sprinkled from the upper part of the packed bed 21. The circulating water W sprayed from the upper part of the packed bed 21 flows down through the filler constituting the packed bed 21.

Inside the packed bed 21, the air inside the cooling tower 20 is exhausted upward by the operation of the exhaust fan 24, so that outside air flows from the louver 22.
The inflowing outside air comes into contact with the circulating water W flowing down through the filler, is sucked upward while cooling the circulating water W by heat of vaporization, and is exhausted outside the cooling tower 20 by the exhaust fan 24.
The circulating water W that has flowed down the packed bed 21 and cooled down flows from the lower part of the packed bed 21 to the circulating water tank 25 and is circulated.

When the antifouling device 10 is exposed to the circulating water W flowing down to the circulating water tank 25, the circulating water W is introduced into the storage container 12 through the water passage hole 12 c of the storage container 12, and the circulating water W The water stream contacts the tourmaline carrier 11.
Thereby, an electric charge is generated on the surface of the tourmaline carrier 11, and ionization of the circulating water W is promoted, and the tourmaline is eluted into the circulating water W, thereby purifying the circulating water W, corrosion of the piping, silica, etc. It is possible to prevent the adhesion of scales and the generation of algae and Legionella bacteria.

Here, since the container 12 is arranged substantially in parallel at a predetermined interval, the flow resistance of the circulating water W to the antifouling device 10 can be reduced, so that the flow rate of the circulating water W is increased. Can do. When the flow rate with respect to the tourmaline carrier 11 is fast, the surface charge increases and the amount of tourmaline eluted increases, so that the antifouling effect can be improved.
Moreover, since the container 12 is formed in a flat shape, the amount of tourmaline carrier 11 stacked in the thickness direction is small, and the water flow resistance in the container 12 can be reduced. The flow rate of W can be increased, and the antifouling effect can be improved.
Furthermore, when the flow rate of the circulating water W is fast, the tourmaline carrier 11 swings in the container 12, so that the tourmaline carrier 11 is not easily blocked by slime or the like. Thereby, a high antifouling effect can be maintained over a long period of time.

Since the cooling tower 20 has many opportunities for the circulating water W to come into contact with the outside air and is easily contaminated, the antifouling method of the present invention can be suitably used.

(Example of change)
In the present embodiment, the antifouling apparatus 10 has a configuration in which three storage containers 12 are arranged. However, the number of the storage containers 12 can be arbitrarily changed according to use conditions.

The water flow of the circulating water W can be brought into contact with the tourmaline carrier 11 by being introduced into the container 12 through the holes 12c. Thereby, an electric charge is generated on the surface of the tourmaline carrier 11, and ionization of the circulating water W is promoted, and the tourmaline is eluted into the circulating water W, thereby purifying the circulating water W, corrosion of the piping, silica, etc. It is possible to prevent the adhesion of scales and the generation of algae and Legionella bacteria.
Since the container 12 is arranged substantially in parallel with a predetermined interval by the frame member 13 having water permeability, the water flow resistance of the circulating water W with respect to the antifouling device 10 can be reduced. The speed can be increased and the antifouling effect can be improved.
Moreover, since the container 12 is formed in a flat shape, the amount of tourmaline carrier 11 stacked in the thickness direction is small, and the water flow resistance in the container 12 can be reduced. The flow rate of W can be increased, and the antifouling effect can be improved.

[Second Embodiment]

That is, when the antifouling device 30 is viewed from the upstream side of the water flow F, the farther the container 12 is disposed forward.
The antifouling device 30 is arranged so that the front-rear direction is along the direction of the water flow F of the circulating water W. At this time, the rear part of the antifouling device 30 is arranged to face the discharge pipe 26 side. Thereby, since the water flow resistance in the storage container 12 of the circulating water W can be made small, the flow rate of the circulating water W can be made quick and the antifouling effect can be improved.

  A stopper 13b is formed on the mounting portion 13a of the frame member 13 so as to protrude in order to position the receiving container 12 to be inserted. The stopper 13b is formed so as to be positioned in front of the frame member 13 as it goes downward, and each container 12 is inserted into the frame member 13 to a position where it abuts against the stopper 13b and is disposed at a predetermined position.

When this configuration is used, since the area where the storage container 12 overlaps can be reduced when viewed from the upstream side of the water flow F, the water flow resistance in the storage container 12 can be reduced. The antifouling effect can be improved, and blockage between the tourmaline carriers 11 due to slime or the like can be made difficult to occur.
