Description

UVC LED Reactor for FLOWING WATER STERILIZATION

The present invention relates to a UVC LED reactor for sterilizing flowing water, and more particularly, to a UVC LED reactor installed between pipes to sterilize bacteria or viruses in water with UVC ultraviolet rays while maintaining the flow of water.

In general, as water purification plants disinfect tap water with chlorine gas and supply it, the fear of the spread of water-borne bacteria such as cholera has largely disappeared. .

However, it is known that natural organic matter (NOM) and chlorine that are naturally present in river water react with chlorine to generate new carcinogens such as THM (trihalomethane). The number of cases in which protozoa enters the human body and causes serious diseases is increasing.

Various disinfection and sterilization methods have been tried to overcome the side effects and limitations of chlorine disinfection, and UV disinfection and sterilization as an alternative among them have significant advantages.

Ultraviolet light is known to be more effective than general chemical sterilization methods for sterilizing Cryptosporidium, Giardia or other pathogenic microorganisms in water treatment.

For example, as for the sterilization method, although sterilization with a chemical such as chlorine is common, it is ineffective against resistant microorganisms.

However, UVC has a sterilizing effect on a wide range of microorganisms (eg, viruses, bacteria, worms, protozoa, etc.) including chlorine-resistant bacteria by acting directly on the DNA of living things. is an advantage.

Usually, UV rays refer to all electromagnetic radiation energy with a wavelength range of 10 ~ 400 nm. Divided by wavelength, UVA of 320 ~ 400 nm, UVB of 280 ~ 320 nm, and UVC of 200 ~ 280 nm with shorter wavelengths. is divided into

Since the UVC area is particularly effective in sterilizing microorganisms, the UVC area is used for water, water, and other sterilization purposes.

However, most existing devices that sterilize bacteria or viruses in water with UVC lamps that use UVC ultraviolet rays are contact-type in which UVC lamps are put directly into water for sterilization. It is necessary to work in a locked state with water, and eventually there is a disadvantage in terms of time or workability.

In addition, although there are some types of irradiating UVC ultraviolet rays to flowing water, they are structurally complicated, so handling is inconvenient during work, and there are disadvantages in usability such as difficulty in connecting to existing or new pipes and using them.

In particular, under the condition of sterilizing a large amount of water, the existing types have a disadvantage in that the sterilization effect is poor because it is difficult to sufficiently contact UVC ultraviolet rays and water.

In addition, the UVC LED reactor for sterilizing the flowing water includes a water supply pipe 10 for supplying water before sterilization and a water discharge pipe 12 for discharging water after sterilization.

The water supply pipe 10 and the water discharge pipe 12 have a circular pipe shape, and are vertically installed in a side-by-side posture on one side wall of the reactor body 35 and the opposite side wall of the reactor body 35 .

Here, the water supply pipe 10 and the water discharge pipe 12 may be formed in the form of two rows of pipes communicating as one while taking a “C” shape.

In addition, a supply pipe valve 37 and a discharge pipe valve 38 are respectively installed in the beginning section of the water supply pipe 10 and the end section of the water discharge pipe 12, and the supply pipe valve 37 and the discharge pipe valve 38 are installed in this way. ) is composed of a manual or electromagnetic valve to control the water flowing into the water supply pipe 10 and the water discharge pipe 12 when necessary.

In addition, the UVC LED reactor that sterilizes the flowing water distributes the water supplied from the water supply pipe 10 to each reactor module 16, and distributes the sterilized water from each reactor module 16 to the water discharge pipe ( 12) includes a plurality of supply-side branch pipes 11 and a plurality of discharge-side branch pipes 13 as a means for sending to the side.

The supply-side branch pipe 11 serves to send water to the reactor module 16 side of each row forming a parallel combination while branching at regular intervals along the longitudinal direction of the water supply pipe 10 .

At this time, the supply-side branch pipe 11 can be connected to the reactor module 16 at the front of the rows of reactor modules 16 arranged in series.

Accordingly, water flowing along the supply-side branch pipe 11 can be sent to the reactor modules 16 of each row forming a parallel combination through each supply-side branch pipe 11 .

In addition, each of the supply-side branch pipes 11 is provided with an on/off valve 34 capable of manually or automatically opening/closing operation, and accordingly each on/off valve 34 is selectively turned ON (opened) or OFF ( closed), it is possible to selectively use the reactor modules 16 in each row in parallel according to the processing capacity of water supplied from the pipe on the side of use.

That is, the number of reactor modules 16 used can be appropriately adjusted according to the water treatment capacity.

The discharge-side branch pipe 13 serves to receive water discharged from the reactor module 16 side of each row forming a parallel combination while branching at regular intervals along the longitudinal direction of the water discharge pipe 12 .

At this time, the discharge side branch pipe 13 can be connected to the reactor module 16 located at the rearmost among the rows of reactor modules 16 arranged in series.

Accordingly, the water discharged from the reactor modules 16 of each row forming the parallel combination can be sent to the water discharge pipe 12 through each discharge side branch pipe 13 .

In addition, an on/off valve 34 capable of manually or automatically opening/closing operation is installed in each of the discharge-side branch pipes 13, and accordingly, each on/off valve 34 is selectively turned ON (opened) or OFF When (closed) is operated, the reactor modules 16 in each row in parallel can be selectively used according to the processing capacity of water supplied from the pipe on the side of use.

That is, by opening or closing the opening/closing valve 34 to open or block the flow of water from the reactor module 16 side of each row, the number of reactor modules 16 used can be appropriately adjusted according to the water treatment capacity.

In addition, the UVC LED reactor for sterilizing flowing water includes a plurality of reactor modules 16 as a means for substantially sterilizing water by irradiating ultraviolet rays to the water.

The reactor module 16 is equipped with a 265nm UV-LED, which has a high inactivation effect such as bacteria, viruses, and protozoa, and adopts a structure that increases the efficiency of using ultraviolet rays to realize high sterilization effect, and to achieve sterilization effect between water input and power At the same time, it has the advantage of easy pipe installation by applying standard drain lines.

To this end, the reactor module 16 is composed of a combination of a UVC irradiator 14 for irradiating ultraviolet rays and a water chamber 15 for providing a space for water to flow.

For example, the reactor module 16 has a structure in which the UVC irradiator 14 and the water chamber 15 are vertically coupled integrally.

In particular, the reactor modules 16 are connected in series form by a connecting pipe 17 and connected between the supply side branch pipe 11 and the discharge side branch pipe 13 at the same time to be arranged in parallel along a horizontal line. will form a column of

Accordingly, the water entering through the supply-side branch pipe 11 can pass through each reactor module 16 constituting a row one by one in turn, and then exit through the discharge-side branch pipe 13 .

In this way, through the series connection of the reactor module 16, the water receives a sufficient amount of UV irradiation, and eventually, the effective concentration of UV light is irradiated to the flowing water to expand the sterilization concentration, so that E. coli or Salmonella in water, as well as more than that It is possible to effectively kill river protozoa.

In addition, a column formed by combining a plurality of reactor modules 16 in series may be formed of a plurality of columns, and each column at this time may be arranged in parallel.

That is, a plurality of rows made by gathering the reactor modules 16 are provided, and the plurality of rows provided in this way is located between the water supply pipe 10 and the water discharge pipe 12 on both sides along the vertical direction of the reactor body 25 . It can be connected to the water supply pipe 10 side and the water discharge pipe 12 side while being arranged at regular intervals.

Accordingly, the water supplied through each supply-side branch pipe 11 of the water supply pipe 10 passes through the reactor modules 16 of each row in parallel at the same time and then exits through each discharge-side branch pipe 13 . be able to

By connecting each row of the reactor modules 16 forming the series combination in parallel, the water sterilization treatment capacity can be expanded.

In addition, since each row of the reactor modules 16 forming a series combination can be increased in parallel combination, it is possible to easily adjust the processing capacity according to each use such as small-scale or large-scale processing of various capacities.

Here, each of the reactor modules 16 constituting the series combination can be installed in a structure supported on the module support 39 in the form of a rectangular plate installed on the inner wall of the reactor body 35 .

In addition, the UVC LED reactor for sterilizing the flowing water includes a bypass pipe 20 as a means for bypassing the water directed to the reactor module 16 side.

The bypass pipe 20 is connected and installed between the water supply pipe 10 and the water discharge pipe 12 at the lower inside of the reactor body 35 .

In addition, a manual or automatic inlet valve 18 is installed at a position adjacent to the connection portion of the bypass pipe 20 with the water supply pipe 10 side, and the water discharge pipe 12 of the bypass pipe 20 is installed. A manual or automatic outlet valve 19 is also installed at a position adjacent to the connection portion with the side.

Accordingly, when it is confirmed that water is flowing normally before starting the reactor, when checking, repairing, or replacing the reactor is required, the supply pipe valve 37 in the water supply pipe 10 and the water discharge pipe 12 and Close the discharge pipe valve 38, open the inlet valve 18 and the outlet valve 19 in the bypass pipe 20 to watch the water exit through the water discharge pipe 12, etc. to control the flow of water. It can be checked, or the reactor module 16 can be checked while the water is bypassed.

As described above, the UVC LED reactor extension method for sterilizing flowing water is a method of connecting reactors in series and/or parallel when sterilizing a sterilization concentration or capacity higher than the capacity. Unlike the method of increasing the size, it is a method of expanding the composition of the unit reactor. In this method, the problems such as structurally blocking UV rays or reducing the exposure time according to the direction of the water flow are minimized, so that flowing water in all sections is irradiated. It becomes possible to uniformly control the concentration of UVC received.

Usually Escherichia coli or Salmonella are sterilized when irradiated with ultraviolet rays, but the stronger protozoa form cysts, so they can only be sterilized by irradiating a large amount of ultraviolet ray.

Among the wavelengths of ultraviolet rays, the 265nm wavelength penetrates the cyst and destroys the nucleotide sequence of DNA and m-RNA of the cell within a short time, preventing further proliferation, and ultimately has the ability to kill bacteria.

In this process, the required UV concentration is 40 mJ/cm 2 , that is, when the 265 nm wavelength is not irradiated with a concentration of 40 mJ/cm 2 , unsterilized bacteria may remain, and this can be achieved by re-proliferation of the bacteria.

After all, there is an essential difference between simply irradiating ultraviolet light to flowing water and allowing the flowing water to be irradiated with ultraviolet light at an effective concentration.

In this regard, in the case of the UV irradiation concentration, when 50 mW is irradiated for 1 second, the amount is 50 mJ/cm 2 .

In the reactor of the present invention, through the design of the UV light source and the module structure, the water passing through the reactor must receive an irradiation dose of 40 mJ/cm 2 or more, and only in this way is effective in sterilizing the flowing water.

The reactor of the present invention has an output of 50 mW and can sterilize flowing water at a production power of 40 liters per minute.

In addition, a method was implemented to sterilize water by applying the same principle to a higher capacity.

That is, a 50mW reactor was configured in a modular way, and the sterilization concentration was expanded through serial connection and capacity was expanded through parallel connection.

3 is a perspective view illustrating a UVC irradiation unit of a reactor module in a UVC LED reactor for sterilizing flowing water according to an embodiment of the present invention.

As shown in FIG. 3, the UVC irradiation unit 14 of the reactor module 16 includes an SMPS case 21, and inside the SMPS case 21, the SMPS ( 22) is installed.

And, at the lower end of the SMPS case 21, a circular block-shaped PCB body 23 having a groove on the bottom is installed in a fastening structure, and a PCB having an LED 25 in the groove of the PCB body 23 ( 24) is installed, and the PCB 24 at this time is electrically connected to the SMPS 22 side.

A disk-shaped lens 26, for example, a quartz lens, is installed on the bottom of the PCB body 23 along the edge of the groove, and between the lens 26 and the PCB body 23 at this time is Teflon for airtightness. The retainer 40 of the material is interposed, and as the lens 26 is installed on the bottom surface of the PCB body 23 in this way, the PCB 24 and the LED 25 in the PCB body 23 can be closed. .

In addition, a ring-shaped lens cover 27 for supporting the lens 26 is installed on the bottom surface of the PCB body 23 .

Accordingly, when the LED 25 is turned ON by the power supplied from the SMPS 22 , the UV light of the LED 25 passes through the lens 26 and then flows water while coming into contact with the bottom of the lens 26 . By irradiating directly to the water, bacteria, viruses, protozoa, etc. in the water can be completely sterilized.

4 to 6 are perspective views illustrating an example of a water chamber of a reactor module in a UVC LED reactor for sterilizing flowing water according to an embodiment of the present invention.

4 to 6 , the water chamber 15 has a circular block shape, and is installed in a fastening structure on the bottom of the UVC irradiator 14 , that is, on the bottom of the lens cover 27 .

In this water chamber 15, an inlet-side vertical flow path 28a and an outlet-side vertical flow path 29 are formed while maintaining a predetermined distance from each other, and the inside of the water chamber 15, for example, a UVC irradiation unit ( In the space formed while being closed by the lens 26 when combined with 14), the bottom surface of the lens 26 in the UVC irradiation unit 14 while connecting between the entrance-side vertical flow path 28a and the exit-side vertical flow path 29 is A horizontal flow path 30 positioned parallel to the portion is formed.

At this time, the inlet-side vertical flow path 28a is connected to the supply-side branch pipe 11 when the water chamber 15 is located at the front of the series combination, or connected when the water chamber 15 is located in the middle of the series combination. It is connected to the pipe 17, and the outlet side vertical flow path 29 is connected to the outlet side branch pipe 13 when the water chamber 15 is located at the rearmost side of the series combination, or the water chamber 15 is connected to the series combination. If it is located in the middle of the connection pipe 17 is connected.

Here, a one-touch fitting for easy connection with the pipe side can be mounted on the inlet-side vertical flow path 28a and the outlet-side vertical flow path 29, and in the case of the horizontal flow path 30, its vertical width ( For example, the distance between the chamber bottom and the lens bottom) may be 10 mm or less, preferably about 4 mm.

Accordingly, as shown in FIG. 7 , the water supplied to the water chamber 15 enters through the inlet-side vertical flow path 28a on one side and then flows in a straight direction along the horizontal flow path 30, and then flows in the opposite direction to the outlet side of the opposite side. It exits through the vertical flow path 29, and in this process, water flowing along the horizontal flow path 30 flows in contact with the lens 26 and directly receives UV rays at a close distance to the LED 25 side. , a sufficient concentration of UVC can be applied to the water, and eventually all bacteria, viruses, and protozoa in the water can be sterilized.

In other words, as all water flows in the same line from one side to the other while receiving ultraviolet light evenly, it is possible to maximize the sterilization effect.

In addition, in the water chamber 15, water flows directly through the straight horizontal flow path 30 without a space to stay, so that the size of the water chamber 15 can be reduced compactly and the weight can also be reduced, It is possible to secure a better flow rate because the amount of water to be collected is small.

8 to 10 are perspective views illustrating another example of a water chamber of a reactor module in a UVC LED reactor for sterilizing flowing water according to an embodiment of the present invention.

As shown in FIGS. 8 to 10 , the water chamber 15 has a cylindrical housing shape, and is installed in a fastening structure on the bottom of the UVC irradiator 14 , that is, on the bottom of the lens cover 27 .

In the water chamber 15, an inlet-side vertical flow path 28b positioned on the axis of the UVC irradiation unit 14 while being positioned at the center of the chamber bottom is formed, and an inlet-side vertical flow path 28b and 90 on the chamber wall are formed. An outlet-side horizontal flow path 31 is formed at an angle of °, and the interior of the water chamber 15, for example, is closed by the lens 26 when combined with the UVC irradiator 14, and is formed in the inlet side. A chamber-type flow path 32 positioned parallel to the bottom of the lens 26 in the UVC irradiation unit 14 is formed while connecting between the vertical flow path 28b and the outlet-side horizontal flow path 31 .

At this time, the inlet-side vertical flow path 28b is connected to the supply-side branch pipe 11 when the water chamber 15 is located at the front of the series combination, or connected when the water chamber 15 is located in the middle of the series combination. It is connected to the pipe 17, and the outlet side horizontal flow path 31 is connected to the outlet side branch pipe 13 when the water chamber 15 is located at the rearmost side of the series combination, or the water chamber 15 is connected to the series combination. If it is located in the middle of the connection pipe 17 is connected.

Here, a one-touch type fitting for easy connection with the pipe side can be mounted on the inlet side vertical flow path 28b and the outlet side horizontal flow path 31 .

Therefore, as shown in FIG. 11 , the water supplied to the water chamber 15 enters through one inlet-side vertical flow path 28b and then receives UV rays in the chamber-type flow path 32 , and then receives the ultraviolet light in the exit-side horizontal flow path 32 . It flows out through the flow path 31, and in this process, the water passing through the chamber type flow path 32 flows in contact with the lens 26 and directly receives UV rays at a close distance to the LED 25 side. Thus, a sufficient concentration of UVC can be applied to the water, and eventually all bacteria, viruses, and protozoa in the water can be sterilized.

In particular, in the chamber-type flow path 32, a guide pipe 33 in the form of a circular tube that is coaxial with the inlet vertical flow path 28b and protrudes to a predetermined height in the central region of the chamber bottom is vertically formed, and accordingly, the inlet vertical The water entering through the flow path 28b is guided by the guide tube 33 and immediately soars upward to directly receive UV light while colliding with the bottom surface of the UVC irradiator 14 , that is, the lens 26 .

For example, the UVC irradiator 14 directly irradiates UVC 265 nm with an intensity of 50 mW to the chamber-type flow path 32 through the lens 26. From (inlet vertical flow path) to TOP surface (lens surface), it is irradiated with UVC 265 nm and finally reaches the lens 26 irradiated with UVC wavelength, and then flows to the chamber outlet (outlet side horizontal flow path).

In this process, flowing water is exposed to UVC 265nm without breaking or blocking, so that it can receive an irradiation dose of 40mJ/cm2 or more.

On the other hand, the reactor provided in the present invention is characterized in that the LED 25 in the 265 nm wavelength band emitting the most effective light for sterilization is applied.

12 is a graph comparing the inactivation ability by light emission wavelength relatively, and it can be confirmed that 265 nm has a higher sterilization ability than any other light, and the reactor of the present invention can realize high-efficiency sterilization with 265 nm light.

As such, in the present invention, by providing a new type of UVC LED reactor that irradiates UVC ultraviolet rays in water while maintaining the flow of water by directly connecting and installing between the pipes at the place of use, chlorine-resistant bacteria such as viruses, bacteria, and protozoa It can effectively sterilize a wide range of microorganisms including The capacity can be appropriately adjusted (increased or reduced) according to the needs of the user.
