Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of producing high-quality water in buildings such as apartment houses and office buildings.

[0002]

2. Description of the Related Art In recent years, there has been a problem of deterioration of tap water quality, for example, the tap water becomes polluted due to pollution of the tap water source and trihalomethane which is a carcinogen is generated. As one of the countermeasures, attention has been paid to a facility that installs high-quality water production equipment in the basement of a building, manufactures high-quality drinking water, or so-called high-quality water, and supplies it to various places by using activated carbon adsorption or the like. . In the case of producing such high-quality water, it is wasteful to change the water other than for drinking and non-culinary use to high-quality water, such as for toilets and for washing, and the cost is greatly increased. Producing high quality water for the target,
The water is supplied through a dedicated water supply pipe.

[0003]

However, the above-mentioned conventional high-quality water production equipment has a problem that a large space is required for installing the high-quality water production apparatus on the basement floor. There is a problem that pumping energy is required separately to supply water to the upper part of the building.In addition, each house has a dedicated water supply pipe and water supply equipment for supplying high quality water, and a measuring instrument for measuring the amount of water used. In addition, there is a problem that it is extremely difficult to lay a dedicated water supply pipe in an existing building.

[0004] The present invention solves the above-mentioned conventional problems, and is capable of supplying high-quality water in a small space, saving energy and at low cost, and using high-quality water that can use existing water supply equipment. The purpose of the present invention is to provide a manufacturing facility.

[0005]

To this end, the high-quality water production equipment according to claim 1 is installed in an underground water receiving tank 3 installed in a basement 2 of a building 1 and a rooftop 4 and is provided with the underground water receiving tank. A water supply tank 5 connected to a water supply pump 5 and a water supply pipe 8, and an ozone supply device 9 disposed in the water supply pipe 7 in the basement 3. The liquid level of the water supply tank 5 is set to a predetermined value. In the following cases, the pump 6 is operated and ozone is supplied by the ozone supply device 9. The invention according to claim 2 is characterized in that the ozone supply device 9 is connected to the roof water distribution tank 5 according to claim 1. A deozone tank 5c and a water distribution tank 5d are formed by a partition wall 5b having a hole 5a. The pumping pipe 7 and the ozone exhaust pipe 15 are connected to the upper part of the deozone tank 5c.
c, an air ejection nozzle 1 connected to a blower 12
6 is installed. Note that the numbers added to the above configuration are compared with the drawings for easy understanding of the present invention, and the present invention is not limited thereto.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show one embodiment of the high-quality water production facility of the present invention, FIG. 1 is an overall configuration diagram, and FIG. 2 is a cross-sectional view of the ozone supply device of FIG.

In FIG. 1, an underground water tank 3 for storing tap water is installed in a basement 2 of a building 1, a roof water tank 5 is installed on a rooftop 4, and the underground water tank 3 and a roof water tank are installed. Numeral 5 is connected by a water pump 6 and a water pumping pipe 7, and can be supplied to each floor from a roof water tank 5 to a water supply pipe 8.

In the basement 2, an ozone supply device 9 is disposed in a pumping pipe 7 above a water pump 6, and a compressor 10 and an ozone generator 11 are connected to the ozone supply device 9, and as a whole, high-quality water production is performed. The device P is configured.

On the rooftop 4, in addition to the rooftop water receiving tank 5, a blower 12 and an activated carbon tower 13 are installed. Rooftop water tank 5
Is formed with a partition wall 5b having a communication hole 5a to form a deozone tank 5c and a water distribution tank 5d. The pumping pipe 7 and the ozone exhaust pipe 15 are connected to the upper part of the de-ozone tank 5c, the ozone exhaust pipe 15 is connected to the activated carbon tower 13, and the air ejection nozzle 1 is installed to the lower part of the de-ozone tank 5c.
The nozzle 16 is connected to the blower 12. Further, a liquid level sensor 17 for detecting a liquid level is provided above the water distribution tank 5d, and the water supply pipe 8 is connected to a lower part of the water distribution tank 5d.

FIG. 2 shows the ozone supply device 9 of FIG. 1. A pair of support members 7a are provided inside the pumping pipe 7, and an ultraviolet lamp 19 is provided between the support members 7a. An ozone ejection nozzle 20 is provided below the compressor 19, and the ozone ejection nozzle 20 is connected to the compressor 1.
0 and the ozone generator 11. The ozone jet nozzle 20 is used to increase the gas-liquid contact area, that is, to increase the ozone dissolution efficiency, by using one that generates extremely fine bubbles. However, if the height of the building is increased and the length of the pipe from the ozone supply device 9 to the roof water distribution tank 5 is increased, bubbles may associate with each other, and water may protrude at the outlet. for that reason,
The pipe length is preferably 25 to 30 m or less, and when targeting a high-rise building, the high-quality water production apparatus P may be installed on an intermediate floor.

A method for supplying high-quality water having the above configuration will be described. When the water pump 6 is operated, the tap water flows through the underground water receiving tank 3, the ozone supply device 9, and the water pumping pipe 7 to the dewatering tank 5c side of the rooftop water distribution tank 5 to be stored. At this time, the tap water is purified by the irradiation of the ultraviolet lamp 19 and the bubbles of ozone ejected from the ozone ejection nozzle 20 in the ozone supply device 9. The water that has flowed down to the deozonization tank 5c side of the rooftop water distribution tank 5 is blown out of the air jet nozzle 16 by the blower 12 below the deozonization tank 5c, so that ozone bubbles in the tap water are separated and the ozone exhaust pipe 15 Is sent to the activated carbon tower 13 through which the ozone is removed and exhausted to the outside air. The high-quality water from which the ozone bubbles have been removed is stored in the water distribution tank 5d through the communication hole 5a of the partition wall 5b, and the high-quality water is supplied to each use point via the water supply pipe 8.

In the present invention, when the liquid level in the rooftop water distribution tank 5 falls below a predetermined value, the pump 10 and the blower 12 are operated and the compressor 10 and the ozone generator 11 are controlled by the control based on the liquid level sensor 17. I try to drive. The ultraviolet lamp 19 is always energized.

[0013]

As is clear from the above description, according to the present invention, it is possible to produce high quality water using an existing water supply facility without providing a dedicated high quality water supply pipe or the like. Also, apart from the compressor and the ozone generator, a separate high-quality water production device is originally provided in the pumping pipe, so that space can be saved. Also, since the compressor, ozone generator and blower are operated only when the pump is operating, power can be saved.
The energy required for pumping can be reduced by the airlift effect due to the rise of ozone bubbles.
