Subseguently, the air flowing between the apparatus main body 11 and the jacket 14 is sterilized by the irradiation with ultraviolet rays and the air passing between the jacket 14 and the ultraviolet sterilizing lamp 15 is treated with ozone and ultraviolet rays to decompose org. matter such as methanol.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a device for both air purification and water treatment.

[Conventional technology]

Conventionally, in order to sterilize general bacteria contained in water and further oxidize and decompose organic substances such as methanol,
As shown in the figure, a jacket 2 that transmits ultraviolet rays is installed inside the sterilizer main body 1, and the jacket 2
An ultraviolet germicidal lamp 3 whose main wavelength is ultraviolet rays of 254 nm is housed inside the jacket 2, and a device is implemented to flow water to be treated around the outer circumference of the jacket 2.

In addition to the water treatment equipment, an ultraviolet germicidal lamp with main wavelengths of ultraviolet rays of 185 nm and 254 nm is housed inside the sterilizer body, and active oxygen is generated by irradiating ozone generated by the 185 nm ultraviolet rays with 254 nm. It is used to deodorize bad odors in the air, and to sterilize general bacteria using 254 nm.

[Problems to be solved by the invention]

However, if separate devices are provided to sterilize general bacteria contained in water and remove bad odors or general bacteria from the air, there is a drawback that multiple devices are required and the cost is high.

〔Effect of the invention〕

This invention was invented in view of the above points,
The purpose is to provide a combined air purification and water treatment device that can sterilize general bacteria contained in water, decompose organic matter, remove bad odors in the air, and sterilize general bacteria in one device. shall be.

[Means to solve the problem]

The present invention has the following configuration to solve the above problems.

In other words, a jacket that transmits ultraviolet light is installed inside the device body, and an ultraviolet germicidal lamp is installed inside the jacket.

Furthermore, a dust filter is installed at one end of the jacket, and an introduction fan and an ozone decomposition catalyst are installed at the other end.

The water to be treated flowing between the apparatus body and the jacket is treated by irradiating it with ultraviolet rays, and the air passing between the jacket and the ultraviolet germicidal lamp is treated with ozone and ultraviolet rays.

[Function] According to the above-mentioned air purification and water treatment equipment, ultraviolet 25
Irradiates with 4nm to sterilize general bacteria contained in water,
It also decomposes organic substances such as methanol.

In addition, the odor of the air passing between the jacket and the UV germicidal lamp can be deodorized by the active oxygen generated by irradiating ozone generated by 185 nm ultraviolet rays with 254 nm, and general germs can be sterilized with 254 nm.

〔Example〕

The invention will now be explained with reference to FIGS. 1 and 2. In the figure, reference numeral 11 denotes a device main body configured in a cylindrical shape,
It has a feed hole 12 near one end and a feed hole 13 at the other end. Reference numeral 14 denotes a jacket attached to the inside of the device body 1, which is configured to transmit ultraviolet light of 125'4 nm. Further, the jacket 14 is made of, for example, quartz glass. Reference numeral 15 denotes an ultraviolet germicidal lamp installed inside the jacket, and a lamp of a size of 4 watts, 65 watts, 120 watts, etc. is used depending on the amount to be treated. Furthermore, the structure is such that air flows between the jacket 14 and the ultraviolet germicidal lamp 15.

Reference numeral 16 denotes a dust-proof filter provided at one end of the apparatus main body 11, and uses a mesh-like filter, for example. 17 is an air introduction fan provided at the other end of the device main body 11, and 18 is an ozone decomposition catalyst provided at the other end of the device main body 11.

According to this device, when water flows between the device main body 11 and the jacket 14, it is irradiated with ultraviolet TiA 254 nm to sterilize common bacteria 1 such as E. coli in the water. Furthermore, organic substances such as methanol are decomposed by ultraviolet light of 254 nm.

In addition, when air enters through the dust filter 16 of the device main body 11 and passes between the jacket 14 and the ultraviolet sterilizing lamp 5, active oxygen generated by irradiating ozone generated by ultraviolet RIAl 85 nm with 254 nm is generated. It deodorizes bad odors and sterilizes common bacteria such as Escherichia coli at 254 nm. Ozone is decomposed by an ozone decomposition catalyst and then sent to the outside.

〔Effect of the invention〕

As described above, the present invention irradiates the water to be treated flowing between the equipment body and the jacket with ultraviolet rays of 254 nm, sterilizes general bacteria contained in the water, and also sterilizes organic substances such as methanol by the action of the ultraviolet rays. can be disassembled.

In addition, when air passes between the jacket and the UV germicidal lamp, the ozone generated by the 185 nm UV rays absorbs 25
It is possible to deodorize bad odors with the active oxygen generated by irradiation with 4 nm, and sterilizes general bacteria with 254 nm.
- It has the unique effect of being able to perform both air purification and water treatment in one device.

Furthermore, even if one device is used for both air purification and water treatment, the processing capacity of each device will not decrease compared to when each device is installed independently, and the energy consumption will be lower than that of conventional devices. Comparatively speaking, it has the effect of requiring less.
