DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid contact purification device, and more particularly, to a fluid contact purification device in a water utilization device such as a cooling tower or a water storage tank.
The present invention relates to a fluid contact purification device for preventing generation of bacteria and algae, and adhesion and water contamination.

2. Description of the Related Art Conventionally, in a cooling tower, a water storage tank or a water supply pipe, various cooling water tanks, etc., there is a problem that proliferation of microorganisms such as bacteria and algae causes water pollution and malfunction of facilities. As a countermeasure, (1) dissolve and use agents such as bactericides and slime control agents,
(2) Cleaning the inside of a pipe or a water tank, (3) filtering with a filter, (4) shading, and suppressing the generation and growth of algae have been adopted.

[0003] However, in the case of the above (1), the expiration date of the drug is limited, so that the cost of the drug is increased. In the case of (1), the equipment cost is high, and fine microorganisms cannot be removed. In the case of (4), the equipment cost for shading is high, and complete shading is difficult. ing.

Means for Solving the Problems The present invention solves the above-mentioned problems, and the gist of the present invention is to provide a device for purifying water by bringing a particulate antibacterial material into contact with water to be treated. It is composed of a U-shaped or downwardly inclined sedimentation section, contact section, introduction flow path, delivery flow path, bypass flow path, and outflow flow path. introduced to the contact portion loaded with, delivery from the contact portion
A fluidized contact purification apparatus characterized in that treated water flowing out through a flow path is circulated through a bypass flow path and / or discharged through a discharge flow path.

[0005] The water to be treated is forcibly introduced into the contact portion of the fluidized contact purification device of the present invention from a water utilization device or the like, and is fluidly stirred in the contact portion in which the particulate antibacterial material is loaded. The surface is constantly activated by collision, and the antibacterial agent in the particulate antibacterial material and the copper powder exhibit a synergistic effect, exhibiting an antibacterial effect from the initial stage for a long time, and the generation and proliferation of microorganisms such as bacteria and algae in the water to be treated. And water pollution is prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the drawings. FIG. 1 shows an embodiment of the present invention in a schematic perspective view, and FIG. 2 shows a settling section and a contact section of the present invention in a side schematic view.

As shown in a schematic perspective view in FIG. 1, the present invention provides a water supply pump 1, a sedimentation section 2 formed in a U-shape or downward inclination, a contact section 3, an introduction flow path 4-1 and a delivery flow path 4- 2, the bypass flow path 4-3 and the lead-out flow path 4-4, and between the water supply pump 1 and the contact portion 3, an introduction flow path 4-1 provided with an adjustment valve 5-1 and the introduction flow path A substantially U-shaped precipitation part 2 is connected to 4-1. The outlet of the precipitation part 2 is directly connected to the bottom of the contact part 3 loaded with the particulate antibacterial material A without using a strainer. The settling portion 2 may be formed to be substantially U-shaped or inclined downward from the bottom of the contact portion 3.

The delivery channel 4 is provided above the contact portion 3.
-2 is directly connected without passing through the strainer, and the other end of the delivery flow path 4-2 is branched, and one of the ends is adjusted to the adjusting valve 5.
-2 as a bypass flow path 4-3 with the introduction flow path
4-1, delivery channel 4-2, bypass channel 4-3 and derivation
The flow path composed of the flow path 4-4 and the like is referred to as a circulation / delivery flow path 4.
are doing.

In order to treat the to-be-processed water B-1 according to the present invention, the water is first passed from the water supply pump 1 through the introduction flow path 4-1.
Water flows in the sedimentation section 2 in the direction of the arrow, and then the particulate antibacterial material A loaded with the water-to-be-processed B-1 flowing into the contact section 3 is flow-stirred to cause contact and collision between the particulate antibacterial materials A. After activating the surface and purifying the water to be treated B-1 at the same time,
The liquid is sent out from the upper part of the contact portion 3 to the delivery flow path 4-2, and the adjustment valve 5-2 is closed and led out to the lead-out flow path 4-4 in the direction of the arrow. If necessary, the adjustment valve 5-2 is adjusted. And a part of the treated water 5-2 is introduced through the bypass passage 4-3 to the introduction passage 4
-1 and circulated.

The sedimentation section 2 connected between the introduction flow path 4-1 and the contact section 3 is formed in a U-shape or a downwardly inclined shape. As shown in the schematic side view of FIG. 1, the granular antibacterial material A settling from the contact portion 3 does not deposit and flow backward to the water pump side, but diffuses and flows into the state shown in FIG. Further, since no strainer or the like for supporting and fixing the particulate antibacterial material A is attached to the bottom and the top of the contact portion 3, clogging does not occur. And it can adjust by the adjustment valve 5-1 so that the granular antibacterial material A may not flow out of the contact part 3 to the delivery flow path 4-2.

[0011]

Since the present invention has the above-described structure, the following effects can be obtained. That is, when the water to be treated is flow-stirred at the contact portion loaded with the particulate antibacterial material, and the granular antibacterial materials are brought into contact with each other and treated by collision, the surface of the granular antibacterial material is activated, and at the same time, the antibacterial action extends from the initial stage to a long term. Water pollution can be effectively prevented and purified over the entire time, and the flow state of the particulate antibacterial material can be appropriately maintained by adjusting the water flow velocity in the introduction flow path, and the operation of the water supply pump is required. It is possible to prevent the particulate antibacterial material from flowing out of the contact portion, and to prevent the backflow of the particulate antibacterial material due to the stoppage of the water supply pump by providing the sedimentation portion.
