Description

Technical Field

[0001] This invention relates to a water treatment sterilization device and method, and more particularly to a water treatment sterilization device and method using ultraviolet light. Background Technology

[0002] With the increasing global water shortage and growing public health awareness, the demand for efficient, safe, and environmentally friendly disinfection technologies in the water treatment sector is becoming increasingly urgent. Bacteria, viruses, parasite eggs, and other pathogenic microorganisms in water are major causes of waterborne infectious diseases, making disinfection a core element in ensuring the safety of drinking water, industrial water, and reclaimed water. Currently, mainstream water treatment disinfection technologies include chemical disinfection (such as chlorination and ozone disinfection) and physical disinfection (such as ultraviolet disinfection and filtration). Chlorination disinfection was once widely used due to its low cost and ease of operation; however, the reaction of chlorine with organic matter in water produces carcinogenic disinfection byproducts such as chloroform and haloacetic acids, and its effectiveness in inactivating parasites such as Cryptosporidium and Giardia is limited. Furthermore, the residual chlorine taste affects the palatability of the water, and long-term use may corrode water pipes. While ozone disinfection has high sterilization efficiency, the equipment investment and operating costs are high, requiring complex ozone generation systems, and it may react with bromide ions in water to produce harmful byproducts such as bromate. Ultraviolet disinfection, on the other hand, is prone to dead zones, leading to incomplete disinfection. Summary of the Invention

[0003] The purpose of this invention is to provide a water treatment sterilization device and method. It can achieve sterilization from all angles, has a good irradiation effect, effectively improves the sterilization effect, and achieves effective heat dissipation of the ultraviolet germicidal lamps through a cooling system, avoiding heat accumulation in the ultraviolet germicidal lamps due to the increased number of LED beads, thus improving product lifespan.

The water treatment tank is provided with a first inlet pipe and a first outlet pipe at the front and rear ends of the upper side, respectively. The water treatment tank is provided with one or more sets of ultraviolet sterilization lamps. The ultraviolet sterilization lamps include lamp holders at both ends, and a copper tube is provided between the two lamp holders. The copper tube is covered with an installation tube composed of two sets of mounting parts. The outer cross section of the installation tube is a regular polygon. Each surface of the outer surface of the mounting parts is provided with an LED lamp bead. A lamp cover is provided outside the installation tube. Cooling systems are connected to both ends of the copper tube. The cooling system includes a pump located on one side of the first inlet pipe. A second inlet pipe and a second outlet pipe are arranged sequentially from top to bottom on one side of the pump. The end of the second inlet pipe is connected to the first inlet pipe. The second outlet pipe is connected to the inlet of the copper tube. A return pipe connected to the first inlet pipe is provided on the rear side of the outlet of the copper tube.

[0005] In the aforementioned water treatment sterilization device, the inner side of the mounting component is provided with a mounting groove corresponding to the outer surface of the copper pipe.

[0006] In the aforementioned water treatment sterilization device, the installation pipe is a regular polygon with more than 3 sides.

[0008] In the aforementioned water treatment sterilization device, the interface between the return pipe and the first inlet pipe is located below the interface between the second inlet pipe and the first inlet pipe.

[0009] In the aforementioned water treatment sterilization device, the connection section between the second water outlet pipe and the copper pipe and the connection end between the third water outlet pipe and the copper pipe are equipped with temperature sensors for detecting water temperature.

[0010] The aforementioned method of using a water treatment sterilization device includes: turning on the power supply of the ultraviolet sterilization lamp, water entering through the first inlet pipe, most of the water directly entering the water treatment tank and being sterilized under the irradiation of the ultraviolet sterilization lamp, a small portion of the water being pumped to the copper pipe to cool the ultraviolet sterilization lamp, and the water passing through the copper pipe being connected to the first inlet pipe through the return pipe and entering the water treatment tank for sterilization treatment.

[0011] In the aforementioned water treatment sterilization device, a third inlet pipe connected to a heat exchanger is provided in the middle of the second inlet pipe, a third outlet pipe connected to the heat exchanger is provided on one side of the return pipe, and a cooler is provided on one side of the heat exchanger.

[0012] In the aforementioned water treatment sterilization device, control valves are provided on the second inlet pipe, the third inlet pipe, the third outlet pipe, and the return pipe.

[0013] The aforementioned method of using a water treatment sterilization device includes: turning on the power supply of the ultraviolet sterilization lamp; transmitting information detected by the temperature sensor to the controller for judgment; if the temperature is lower than the threshold, the control valves on the second inlet pipe and the return pipe are in the open state, and the control valves on the third inlet pipe and the third outlet pipe are in the closed state; water enters from the first inlet pipe, and most of the water directly enters the water treatment tank for sterilization under the irradiation of the ultraviolet sterilization lamp; a small portion of the water is pumped to the copper pipe to cool the ultraviolet sterilization lamp; if the temperature is higher than the threshold, the control valves on the third inlet pipe and the third outlet pipe are both in the open state, and the control valves on the second inlet pipe and the return pipe are in the closed state; at the same time, the heat exchanger and the cooler work, and the water entering the copper pipe is cooled down by the heat exchanger and the cooler, so that the temperature is lower than the threshold, thus cooling the ultraviolet sterilization lamp.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This application improves the sterilization effect in the water treatment process by setting up a multi-faceted ultraviolet germicidal lamp. Through multi-faceted light emission, the light emitted by the LED beads partially overlaps, achieving 360-degree sterilization.

[0016] 2. This application incorporates a copper pipe inside the ultraviolet germicidal lamp. By supplying water to the copper pipe, the lamp's operating temperature is prevented from becoming too high, thus reducing its lifespan. Copper has a certain bactericidal and bacteriostatic effect, which can prevent bacterial growth inside the copper pipe. The combination of the controller and the temperature sensor enables the regulation of the cooling water source inside the copper pipe, thereby improving the cooling effect.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0024] Example 1. A water treatment sterilization device, configured as follows: Figure 1-4As shown, it includes: a water treatment tank 1, a fixing frame 5 on the lower side of the water treatment tank 1, and a controller 16 on one side of the water treatment tank 1. The water treatment tank 1 has a first inlet pipe 3 and a first outlet pipe 4 at its upper front and rear ends, respectively. The water treatment tank 1 is equipped with one or more sets of ultraviolet germicidal lamps 2. The ultraviolet germicidal lamps 2 include lamp holders 2.6 at both ends. A copper tube 2.1 is provided between the two lamp holders 2.6. The copper tube 2.1 is sleeved with an installation tube 2.3 composed of two sets of mounting parts 2.2. The outer cross section of the installation tube 2.3 is... It is a regular polygon. Each surface of the outer surface of the mounting part 2.2 is provided with LED beads 2.4. The mounting tube 2.3 is provided with a lamp cover 2.5. The two ends of the copper tube 2.1 are connected to a cooling system. The cooling system includes a pump 6 located on one side of the first water inlet pipe 3. The pump 6 is provided with a second water inlet pipe 7 and a second water outlet pipe 8 from top to bottom on one side. The end of the second water inlet pipe 7 is connected to the first water inlet pipe 3. The second water outlet pipe 8 is connected to the water inlet of the copper tube 2.1. A return pipe 12 connected to the first water inlet pipe 3 is provided on the rear side of the water outlet of the copper tube 2.1. The lampshade 2.5 is a cylindrical lampshade made of quartz sand. The lamp holder 2.6 has a corresponding slot for the lampshade. When installing the ultraviolet germicidal lamp, the water treatment tank 1 has installation ports at both ends corresponding to the ultraviolet germicidal lamp 2. The ultraviolet germicidal lamp is sealed by setting an outer fastener 17, an inner fastener 18, a hook 19 and a sealing strip 20 on both sides of the installation port. The sealing strip 20 is set on the end face of the outer fastener 17 and the hook 19 and on the contact side between the inner fastener 18 and the lampshade 2.5. The outer fastener has an internal thread. The hook 19 has an external thread on the outside and an internal thread on the inside. The inner fastener has an external thread on the outside. By rotating the outer fastener 17, the end face of the hook 19 and the end face of the outer fastener continuously approach each other and clamp at the installation port of the water treatment tank. Then, the inner fastener is rotated to squeeze the sealing strip, deform it and improve the sealing effect. The number of sealing strips can be one or more sets to improve the sealing installation effect.

[0025] The mounting component 2.2 has a mounting groove 2.7 on its inner side that corresponds to the outer surface of the copper tube 2.1. The two sets of mounting components 2.2 are connected by bolts at their ends. The mounting tube formed by the combination of the two sets of mounting components has an outer cross-section of a regular polygon and an inner cross-section of a circle corresponding to the copper tube 2.1. Furthermore, the mounting component 2.2 has a radially arranged connecting part at its end for easier connection; however, the connecting part is relatively short to avoid affecting the illumination effect of the LED beads.

[0026] The mounting tube 2.3 is a regular polygon with more than 3 sides. When the outer surface of the mounting tube can accommodate the installation of LED beads, increasing the number of sides of the mounting tube 2.3 is beneficial to improving the illumination effect.

[0027] The number of ultraviolet germicidal lamps 2 is greater than 3 sets. One set of ultraviolet germicidal lamps 2 is located on the axis of the water treatment tank 1, and the remaining ultraviolet germicidal lamps 2 are evenly distributed with the axis of the water treatment tank 1 as the center.

[0028] The interface between the return pipe 12 and the first inlet pipe 3 is located below the interface between the second inlet pipe 7 and the first inlet pipe 3.

[0029] The connection section between the second water outlet pipe 8 and the copper pipe 2.1 and the connection end between the third water outlet pipe 11 and the copper pipe 2.1 are equipped with temperature sensors 14 for detecting water temperature.

[0030] The above-mentioned water treatment sterilization device is used as follows: turn on the power of the ultraviolet sterilization lamp 2, water enters from the first water inlet pipe 3, most of the water directly enters the water treatment tank 1 and is sterilized under the irradiation of the ultraviolet sterilization lamp 2, a small part of the water is transported to the copper pipe 2.1 by the pump 6 to cool the ultraviolet sterilization lamp 2, and the water passing through the copper pipe 2.1 will enter the first water inlet pipe 3 through the return pipe 12 and enter the water treatment tank 1 for sterilization treatment.

[0031] Example 2. Based on Example 1, control valves 15 are provided on the second water inlet pipe 7, the third water inlet pipe 10, the third water outlet pipe 11, and the return pipe 12.

[0032] The second water inlet pipe 7 is provided with a third water inlet pipe 10 connected to the heat exchanger 9 in the middle, and a third water outlet pipe 11 connected to the heat exchanger 9 is provided on one side of the return pipe 12. A cooler 13 is provided on one side of the heat exchanger 9.

[0033] The method of a water treatment sterilization device described in Example 2 includes: turning on the power supply of the ultraviolet sterilization lamp 2; transmitting the information detected by the temperature sensor 14 to the controller 16 for judgment; if the temperature is lower than the threshold, the control valves 15 on the second inlet pipe 7 and the return pipe 12 are in the open state, and the control valves 15 on the third inlet pipe 10 and the third outlet pipe 11 are in the closed state; water enters from the first inlet pipe 3, and most of the water directly enters the water treatment tank 1 for sterilization under the irradiation of the ultraviolet sterilization lamp 2; a small portion of the water is transported to the copper pipe 2.1 by the pump 6 to cool the ultraviolet sterilization lamp 2; if the temperature is higher than the threshold, the control valves 15 on the third inlet pipe 10 and the third outlet pipe 11 are both in the open state, and the control valves 15 on the second inlet pipe 7 and the return pipe 12 are in the closed state; at the same time, the heat exchanger 9 and the cooler 13 work, and the water entering the copper pipe 2.1 is cooled down by the heat exchanger 9 and the cooler 13, so that the temperature is lower than the threshold, thus cooling the ultraviolet sterilization lamp 2.

[0034] The principle of this invention: When processing external water sources, the temperature sensor 14 detects the temperature of the cooling water entering the copper pipe 2.1. The signal is transmitted to the controller 16 via wired or wireless means. If the temperature is lower than the set threshold, i.e., the cooling water temperature meets the cooling function for the ultraviolet germicidal lamp, the control valve 15 on the second inlet pipe 7 and the return pipe 12 is open, and the control valve 15 on the third inlet pipe 10 and the third outlet pipe 11 is closed. That is, the cooling system is inactive. At this time, most of the water entering the first inlet pipe 3 is sent to the water treatment tank 1 for processing, and a small portion of the water is sent to the copper pipe 2.1 by the pump 6 to cool the ultraviolet germicidal lamp 2. The cooled water is then sent to the water treatment tank 1 for processing via the return pipe. When the detected temperature is higher than the set threshold, the control valves 15 on the third inlet pipe 10 and the third outlet pipe 11 are both in the open state, while the control valves 15 on the second inlet pipe 7 and the return pipe 12 are in the closed state. At the same time, the heat exchanger 9 and the cooler 13 work, and the water entering the copper pipe 2.1 will be cooled down by the heat exchanger 9 and the cooler 13, so that the temperature is lower than the threshold, thereby cooling the ultraviolet germicidal lamp 2.
