Description

Technical Field

[0001] The utility model relates to the technical field of water treatment devices, in particular to an ultraviolet sterilizer suitable for water treatment. Background Art

[0002] We know that the luminous efficiency of conventional low-pressure UV lamps is primarily determined by the mercury vapor pressure within the tube. For common T5-T8 UV lamps, efficiency is highest when the mercury vapor pressure is between 1.2 and 1 Pa. This mercury vapor pressure, in turn, is closely related to the cold-end temperature of the tube wall. The cold-end temperature refers to the area of ​​the UV lamp wall where the temperature is lowest during operation. When this temperature is between 42 and 45°C, the mercury vapor pressure within the tube is between 1.2 and 1 Pa, resulting in the highest luminous efficiency.

[0003] The UV lamps we routinely use for water treatment are mostly T5 or T6 in diameter. The optimal operating cold-end temperature for these lamps is below 45°C. When the lamps are low-power and low-power, they can maintain the tube wall temperature within this range through natural heat dissipation. However, in many applications, such as industrial and environmental protection, high-power UV lamps are required to improve treatment efficiency and reduce equipment size and cost. These high-power and high-power lamps make it impossible to maintain the cold-end temperature below 45°C through natural heat dissipation, resulting in reduced luminous efficiency.

[0004] Based on the above problems, there is an urgent need for an ultraviolet lamp that can effectively maintain the cold end temperature of the tube wall below 45°C. Utility Model Content

[0005] In view of the fact that current high-power ultraviolet lamps are difficult to maintain the cold end temperature at 45°C by relying on natural heat dissipation, the present application provides an ultraviolet sterilizer suitable for water treatment to solve the above problem.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] An embodiment of the present application discloses an ultraviolet sterilizer suitable for water treatment, comprising an ultraviolet lamp tube and a quartz sleeve sleeved on the outside of the ultraviolet lamp tube, wherein the outer wall of the ultraviolet lamp tube is tightly attached to the inner wall of the quartz sleeve, and a lamp head and a lamp tail are respectively fixed at both ends of the ultraviolet lamp tube, and the lamp head and the lamp tail are arranged on the inner side of the quartz sleeve.

[0008] Optionally, the maximum outer diameters of the lamp head and the lamp tail are smaller than the diameter of the outer wall of the ultraviolet lamp tube.

[0009] Optionally, a U-shaped groove is provided on one side of the lamp tail and the lamp head facing the ultraviolet lamp tube, and both side baffles of the U-shaped groove are provided with notches facing inward.

[0010] Optionally, wire grooves are provided on the inner top surfaces of the two recesses.

[0011] Optionally, four through holes are opened on the outer top surface of the lamp holder, and the four through holes are used for riveting four columnar metal electrodes with through holes opened on the top surface.

[0012] Optionally, an electric wire is connected between the lamp head and the lamp tail, and the electric wire is arranged on a side of the ultraviolet lamp tube where the outer wall is not in contact with the inner wall of the quartz sleeve.

[0013] Optionally, clamping positions are provided at both ends of the ultraviolet lamp tube, the width of the clamping positions is smaller than the distance between the baffles on both sides of the U-shaped groove, and the clamping positions are clamped to the inner side of the U-shaped groove by adhesive.

[0014] The beneficial effects of the present invention are:

[0015] In the device provided by the utility model, the ultraviolet lamp tube contacts the side wall of the quartz sleeve. When the device is placed in water for sterilization, the heat on the ultraviolet lamp tube is quickly transferred to the quartz sleeve, and the heat on the quartz sleeve is quickly exchanged with the surrounding water. Compared with simply placing the ultraviolet lamp tube in a closed space that is difficult to contact with surrounding equipment, the heat transfer is faster and heat can be dissipated efficiently.

[0024] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obscuring the description of the present application with unnecessary detail.

[0025] It should be understood that when used in the present specification and the appended claims, the term "comprising" indicates the presence of described features, integers, steps, operations, elements and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or collections thereof.

[0026] See also Figure 1 and Figure 5 , like the original ultraviolet lamp tube 1, the lamp head 3 and lamp tail 4 at both ends are sleeved on the glass outer wall of the lamp tube. Its diameter is larger than the glass diameter of the lamp tube, so when the lamp tube is assembled into the quartz sleeve 2, there is an air gap between the quartz sleeve 2 and the lamp glass, and air is a poor conductor of heat, making it difficult to dissipate heat. Heat accumulates in the quartz sleeve 2, which will quickly heat up and affect the sterilization effect. Based on the above problems, the embodiment of the present application discloses an ultraviolet sterilizer suitable for water treatment, including an ultraviolet lamp tube 1, a quartz sleeve 2 sleeved on the outside of the ultraviolet lamp tube 1, the outer wall of the ultraviolet lamp tube 1 is tightly attached to the inner wall of the quartz sleeve 2, and the two sides of the ultraviolet lamp tube 1 are respectively fixed with a lamp head 3 and a lamp tail 4, the lamp head 3 and the lamp tail 4 are fixed to the two sides of the ultraviolet lamp tube 1. The tail 4 is arranged on the inner side of the quartz sleeve 2. The design of this application arranges the lamp head 3 and the lamp tail 4 on the inner side of the quartz sleeve 2, so that the outer wall of the ultraviolet lamp tube 1 can be close to the inner wall of the quartz sleeve 2. After a period of use, the ultraviolet lamp tube 1 will continuously generate heat, and the ultraviolet lamp tube 1 is in close contact with the quartz sleeve 2. The ultraviolet lamp tube 1 has good thermal conductivity and can quickly transfer heat to the quartz sleeve 2. The quartz sleeve 2 is in contact with the water on the outside, which can realize the transfer of the absorbed heat to the water again, thereby achieving effective heat dissipation and temperature control, and ensuring the sterilization effect of the ultraviolet lamp tube 1.

[0027] It's worth noting that the quartz sleeve 2 is in direct contact with the working liquid, allowing the flowing liquid to carry away a significant amount of heat. Therefore, the temperature of the quartz sleeve 2 remains roughly consistent with that of the working liquid. When the lamp tube wall is in direct contact with the quartz sleeve 2, heat generated in the contact area is rapidly transferred through the quartz sleeve 2 into the working liquid, keeping the tube wall temperature in this area below 45°C, thereby creating a cold end during operation. The mercury vapor pressure within the tube during operation is determined by the temperature of the lowest wall temperature (the cold end). This allows the mercury vapor pressure within the tube to remain within an ideal range of 1-1.2 Pa, even if the temperature of other parts of the lamp exceeds 45°C during operation. This ensures that the lamp maintains a high luminous efficiency despite the increased power or power density.

[0028] The maximum outer diameter of the lamp head 3 and the lamp tail 4 is smaller than the diameter of the outer wall of the ultraviolet lamp tube 1. Setting the maximum outer diameter of the lamp head 3 and the lamp tail 4 smaller than the diameter of the outer wall of the ultraviolet lamp tube 1 ensures that the ultraviolet lamp tube 1 is in contact with the quartz sleeve 2, preventing the lamp head 3 and the lamp tail 4 from being too large and supporting the ultraviolet lamp tube 1, thereby leaving a gap between the ultraviolet lamp tube 1 and the quartz sleeve 2.

[0029] The lamp tail 4 and the lamp head 3 have a U-shaped groove 5 on the side facing the ultraviolet lamp tube 1, and both side baffles of the U-shaped groove 5 are provided with notches 6 on the inner side. It is worth mentioning that the above-mentioned U-shaped groove 5 can effectively clamp the ultraviolet lamp tube 1.

[0030] The inner top surfaces of the two recesses 6 are both provided with wire grooves 7 ; the wire grooves 7 can be used for the wires to pass through.

[0031] The outer top surface of the lamp holder 3 is provided with four through holes 8, which are used to rivet four cylindrical metal electrodes 9 with through holes 8 on the top surface. During assembly, the two front electrodes of the lamp tube can be inserted into the through holes 8 of the two metal electrodes 9 of the lamp holder 3. The two rear electrodes of the lamp tube can also be led to the head of the lamp tube via two wires and respectively inserted into the through holes 8 of the remaining two metal electrodes 9 of the lamp holder 3.

[0032] An electric wire 10 is connected between the lamp head 3 and the lamp tail 4 . The electric wire 10 is arranged on a side where the outer wall of the ultraviolet lamp tube 1 does not contact the inner wall of the quartz sleeve 2 .

[0033] Clamping portions 11 are provided at both ends of the ultraviolet lamp 1 . The width of the clamping portions 11 is smaller than the distance between the baffles on both sides of the U-shaped groove 5 . The clamping portions 11 are clamped to the inner side of the U-shaped groove 5 by adhesive.

[0034] Unless otherwise specified, the device components involved in the above embodiments are all conventional device components, and the connection methods and control methods involved are all conventional connection methods and control methods unless otherwise specified.

[0035] The present invention has been described in detail above with reference to the embodiments. However, those skilled in the art will appreciate that, without departing from the spirit of the present invention, the specific parameters in the above embodiments may be modified to form multiple specific embodiments, which are all within the common variation range of the present invention and will not be described in detail here.
