Abstract

PROBLEM TO BE SOLVED: To exterminate effectively various bacteria and other microorganisms in cooling water and to prevent environmental deterioration due to pollution in refrigerating equipment or the like by constituting a packing material for a cooling tower out of an antibacterial material. SOLUTION: A cooling tower 1 has a cooling water spray pipe 2, a blower 3, an outdoor air intake port 4, an exhaust port 5, an eliminator 6 and a packing material 7 for air-liquid heat exchange, and a large number of plates made of a synthetic resin material, which are assembled with an appropriate space between them, are used for the packing material 7. In this case, the packing material 7 is constituted of the one having antibacterial properties. The antibacterial properties are given to the packing material 7 by a method wherein an antibacterial material is kneaded in the synthetic resin material before molding and then the plates are molded or wherein the antibacterial material is sprinkled on the plates immediately after the molding and made to stick thereon with hardening of the resin material or wherein the surfaces of the plates are coated with the antibacterial material, or others. As for the antibacterial material, the one prepared by forming an antibacterial film of a metal such as silver or copper on the surface of ceramic in the form of fine powder is used desirably, although various kinds of antibacterial materials can be mentioned.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filler for a cooling tower and a cooling tower provided with the filler.

[0002]

The cooling tower is provided with a filler for exchanging heat between gas and liquid. As the filler, a large number of plate members mainly made of synthetic resin are arranged at appropriate intervals.

[0003] Cooling water from the upper sprinkler pipe in the cooling tower is cooled by the outside air sent from the lower part of the filler when falling between the plates of the filler, and is sent to the condenser of the refrigerating apparatus, where it is compressed. The heat refrigerant from the machine is condensed, returns to the cooling tower, and is repeatedly cooled by the cooling tower and sent to the condenser again.

[0004] The cooling water for condensing the refrigerant is a refrigerating device,
When circulating through the cooling tower, it is contaminated by various bacteria and other microorganisms, especially Legionella bacteria, which cause pneumonia. A part of the contaminated cooling water is discharged as a mist outside the cooling tower by a blower when passing through the cooling tower, and the environment near the installation of the cooling tower is deteriorated by bacteria and the like.

The present invention minimizes the number of living bacteria in the mist of the cooling water discharged from the cooling tower, so that environmental degradation can be prevented as much as possible.

[0006]

According to the present invention, in order to solve the above-mentioned problems, the filler of the cooling tower is constituted by an antibacterial material,
The cooling tower was provided with a filler composed of an antibacterial material.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to specific examples shown in the accompanying drawings. In the drawing, reference numeral 1 denotes a cooling tower, 2 denotes a cooling water sprinkler pipe, 3 denotes a blower, 4 denotes an outside air intake, 5 denotes an exhaust port,
6 is an eliminator, 7 is a filler for gas-liquid heat exchange. The filler 7 is formed by assembling a large number of plates 7a... Made of a synthetic resin material at appropriate intervals, and has irregularities 8 formed on the surface of each plate 7a.

In the present invention, the filler 7 is made of an antibacterial material. There are various means for making the filler 7 antibacterial. For example, a plate 7a constituting the filler is used.
... is molded by kneading an antibacterial material into a synthetic resin material before molding, or is coated with an antibacterial material on the plate 7a immediately after the molding, and the antibacterial material is attached by curing the resin material. There is a method of coating the surface of the plate 7a with an antibacterial material. There are various types of the antibacterial material. For example, a material in which an antibacterial film made of a metal such as silver or copper is formed on the surface of a fine powdery ceramic is desirable.

[0009]

According to the present invention described above, the cooling water returned from the condenser to the cooling tower is sprayed on the filler from the sprinkler pipe, but since the filler is antibacterial, the cooling water is As it descends through the packing material, it comes into contact with the surface of the packing material, which considerably kills bacteria and other microorganisms in the cooling water.

In addition, since the surface of the filler has an uneven surface, the cooling water from the sprinkler pipe does not simply pass between the plates of the filler, but must be splashed sideways or obliquely on the uneven surface. The filler passes through the filler in contact with the surface, and the contact area between the filler and the cooling water is large due to the uneven surface, so that germs and other microorganisms can be sufficiently killed.

[0011] Therefore, according to the present invention, the germs and other microorganisms that survive in the spray of the cooling water discharged from the cooling tower are as small as possible. There is an advantage that deterioration of environmental pollution can be prevented.
