BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceramic water heater for use in cooling towers, pools, 24-hour baths, etc. for removing scale and preventing corrosion.

[0002]

2. Description of the Related Art Conventionally, in an open-circulation cooling water system (cooling tower, etc.), a part of the cooling water evaporates, so that scale disturbances caused by concentration of dissolved salts in water (reduction of heat exchange rate, blockage of heat exchanger, In order to prevent slime and corrosion caused by dust in the atmosphere, etc.) and by dust in the atmosphere, chemicals are injected and blow operations are used.

[0003] However, in the above method, chemicals must be used each time, and in connection with the Water Pollution Prevention Law, the drainage surface is restricted and the hands may be rough, which poses many practical problems. .

Although various types using ceramic balls and the like have been disclosed, there is a problem in the components and the structure, and the effect cannot be expected much.

Means for Solving the Problems As means for solving the above problems, a ceramic block is placed in a mesh-like bag coated with ceramic. Further, the composition and the composition ratio of the ceramic are SiO ₂ 70 to 80.
_{%, AL 2 O 3 10~20%} , Fe 2 O 3 1~10%,
It is a Li ₂ O1~10%. Further, a filtering material is put in the bag.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of a ceramic water heater 1 will be described below in detail with reference to the drawings. Component and composition ratio are Si
O ₂ 70-80% ・ AL ₂ O ₃ 10-20% ・ Fe ₂ O
_In a mesh-shaped cylindrical bag 2 formed by coating a mixture of ceramic powder of 31% to 10% · Li ₂ O 1% to 10% with a vinyl chloride solution, the same ceramic as a core material (resin / glass)・ Aluminum) is coated with a large number of spherical ceramic blocks 3. The ceramic block 3 may be formed into a spherical shape by mixing a ceramic powder with a resin, and the processing method and shape are not particularly limited.

As an example of use of the above-mentioned ceramic water heater 1,
For example, when used for the cooling tower K, the ceramic water activation device 1 is placed near the suction port Q1 of the suction pipe Q, and the water M (cooling water) is circulated to contact the water M (cooling water) with the bag 2 and the ceramic block 3. In addition to reducing the values of conductivity, chloride ion, sulfate ion, acid consumption, and total hardness by the oxidation-reduction energy of the ceramic, the treatment based on the passivation theory can be performed, so that the elution (progress) of rust is stopped. And the generation of algae can be prevented.

[Table 3]

As shown in Table 1 above, H9.10.1
In the cooling tower K, make-up water was supplied to a certain level and the test was started.
Was attached, and the data of each item between H9.10.1 and H10.28 was checked. As a result, H9.12.9 was obtained.
By the time of all items have already fallen. Conductivity from 680 μs / cm to 350 μs / cm, chloride ions from 100 mg / l to 35 mg / l, sulfide ions from 100 mg / l to 60 mg / l, acid consumption from 90 mg / l to 65 mg / l, 180mg total hardness
/ L to 135 mg / l. As is well known, water with high conductivity causes factors such as corrosion and scale, as does chloride ion and acid consumption, and all hardness components (calcium salts and magnesium salts) particularly cause scale formation. Can be efficiently cooled by decreasing the value of. Tables 2 and 3 show the results of checking the cooling water pressure and the air conditioner compressor high pressure side pressure after the ceramic water heater 1 was installed. Both pressures were reduced, and scale and slime etc. in the pipe were removed. It seems that the resistance has been reduced,
In fact, scale, slime, etc. settle at the bottom of the cooling tower K. The precipitate is removed periodically.

[0013] As another embodiment, by inserting a plastic spiral filter in a bag, it is easy to attach a biological sample, and the ability to remove soluble organic matter and algae can be greatly improved.

In the above embodiment, the shape and size of the bag of the ceramic water heater and the shape and size of the ceramic block may be set according to the size (capacity) of the cooling tower.

[0015]

According to the above configuration, the following effects can be obtained. 1) By the oxidation-reduction energy of the original ceramic, the value of conductivity, chloride ion, sulfate ion, acid consumption, total hardness, etc. can be reduced, and rust is eluted (play)
Can be stopped (passive treatment), scale, corrosion,
The slime can be dissolved and peeled to increase the operation efficiency of the entire device, and the use of the ceramic for the bag and the block allows more efficient contact with water, thereby improving the processing capacity. 2) By using a plastic helical filter or the like, the ability to remove soluble organic substances, algae and the like can be improved, and this is effective for water purification.
