Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to an internal reflection type high-illuminance excimer processor. Background Technology

[0002] Excimer ultraviolet light sources have unique advantages. Excimers are transient composite molecules formed by inert and halogen gases in an excited state, which rapidly dissociate into atoms in the ground state. The ultraviolet light emitted by excimer ultraviolet light sources has high energy. For example, xenon excimer radiation is mainly a narrow band around 172 nm in vacuum ultraviolet light. The photon energy emitted by it is greater than the bond energy of most organic compounds. Therefore, it can directly decompose and mineralize organic matter in water. On the other hand, water and oxygen have a strong absorption capacity for vacuum ultraviolet radiation, and can generate OH⁻ free radicals and reactive oxygen species without the need for catalysts, thereby initiating chemical reactions that decompose and mineralize organic matter.

[0003] Conventional flow-through UV processors typically use tubular UV lamps as their core light source. Fluids usually flow through the cylindrical outer wall of the lamp to absorb the UV radiation emitted by the tube. However, some processes or photochemical reactions require extremely high levels of UV radiation to complete. This necessitates a significant increase in the power per unit length of the UV lamp. However, a substantial increase in the power per unit length of the UV lamp not only leads to a significant increase in heat generation, negatively impacting the processing, but also increases the manufacturing difficulty of high-power-density UV lamps, thus significantly increasing the cost of the lamp system.

[0004] In addition, traditional excimer laser lamps are usually insulated by a quartz sleeve, but the sleeve absorbs ultraviolet light, which means that not all the ultraviolet energy emitted by the lamp can enter the water, reducing the lamp's efficiency. Secondly, the sleeve also reduces the heat dissipation effect of the water on the lamp, which will further affect the lamp's ultraviolet output efficiency. Utility Model Content

[0005] The purpose of this invention is to address the problems in the existing technology where tubular ultraviolet lamps do not meet the requirements for extremely high ultraviolet radiation, the power of the ultraviolet lamp tube increases significantly, the heat generated by the ultraviolet lamp increases significantly, and the manufacturing process becomes more difficult; moreover, the insulating sleeve reduces the illumination effect after absorbing ultraviolet rays. Therefore, this invention proposes an internal reflection type high-illuminance excimer processor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An internal reflection type high-intensity excimer processor includes an insulating outer cylinder and sealing caps threaded to both ends of the insulating outer cylinder, and further includes: an excimer lamp tube installed inside the insulating outer cylinder, with both ends of the excimer lamp tube abutting against the sealing caps;

[0008] The excimer lamp tube consists of two glass tubes forming the inner and outer bulbs of the excimer ultraviolet lamp. The inner tube of the excimer lamp tube is provided with a spiral inner electrode, and there is a gap between the spirals of the inner electrode that allows light to pass through. The outer ring surface of the excimer lamp tube is fitted with a reflective component, which includes an inner reflective high-voltage outer electrode.

[0009] A liquid supply component is provided on the sealing cover, and the liquid supply component includes two sets of fluid connectors threaded onto the sealing cover.

[0010] Preferably, the excimer lamp tube has U-shaped shoulders at both ends, and the shoulders of the excimer lamp tube are sealed to the inside of the sealing cover by a sealing element.

[0011] Preferably, the surface of the internally reflective high-voltage external electrode is coated with a metal film, or covered with a mirror-finished stainless steel sheet, or covered with an aluminum sheet.

[0012] Preferably, the internally reflective high-voltage external electrode includes a high-voltage external electrode sheet and several arc-shaped concave surfaces. Several arc-shaped concave surfaces are provided on the inner side of the high-voltage external electrode sheet. The arc-shaped concave surfaces may be continuous or discontinuous, and the reflective surface of the arc-shaped concave surfaces faces inward toward the axis of the excimer lamp.

[0013] Preferably, the internally reflective high-voltage external electrode has a ring-shaped sheet structure interwoven into a mesh.

[0014] Preferably, a coolant pipe is fitted on the outer ring surface of the internally reflective high-voltage external electrode. One end of the coolant pipe is connected to a connecting pipe, an electric valve, a heat exchanger, a water pump, and an expansion tank. The other end of the coolant pipe is connected to a return pipe and an expansion tank. A filter screen is installed inside the return pipe.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] An internally reflective high-intensity excimer processor is disclosed. The excimer ultraviolet lamp is designed with a double-layer columnar structure. It consists of two glass tubes of different diameters forming the inner and outer bulbs of the excimer ultraviolet lamp. The two ends of the outer glass tube are constructed with convex-shaped shoulders. A conductive internally reflective high-voltage external electrode is set on the outer ring surface of the outer bulb of the excimer lamp. Light originally directed towards the outside of the excimer lamp is also reflected into the inner columnar space, so that all the ultraviolet energy emitted by the lamp is concentrated in the narrow space of the inner tube, which greatly enhances its ultraviolet radiation intensity.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0023] Reference Figures 1-2 The figure shows an internal reflection type high-intensity excimer processor, including an insulating outer cylinder 1 and sealing caps 2 threaded to both ends of the insulating outer cylinder 1, and also includes an excimer lamp 3 installed inside the insulating outer cylinder 1, with both ends of the excimer lamp 3 abutting against the sealing caps 2.

[0024] Among them, the excimer lamp tube 3 consists of two glass tubes forming the inner and outer bulbs of the excimer ultraviolet lamp. The inner tube of the excimer lamp tube 3 is provided with a spiral inner electrode 6, and there is a gap between the spirals of the inner electrode 6 that allows light to pass through. The outer ring surface of the excimer lamp tube 3 is fitted with a reflective component, which includes an inner reflective high-voltage outer electrode 7.

[0025] A liquid supply component is provided on the sealing cover 2, which includes two sets of fluid connectors 13 threadedly connected to the sealing cover 2.

[0026] In this preferred embodiment, the two ends of the excimer lamp tube 3 form convex shoulders 11, and the shoulders 11 of the excimer lamp tube 3 are sealed to the inside of the sealing cover 2 by a sealing element.

[0027] In this preferred embodiment, the surface of the internally reflective high-voltage external electrode 7 is coated with a metal film, or covered with a mirror stainless steel sheet, or covered with an aluminum sheet.

[0028] Furthermore, the internal reflection type high voltage external electrode 7 includes a high voltage external electrode sheet and several arc-shaped concave surfaces. The several arc-shaped concave surfaces may be continuous or discontinuous. Several arc-shaped concave surfaces are provided on the inner side of the high voltage external electrode sheet, and the reflective surface of the arc-shaped concave surfaces faces inward toward the axis of the excimer lamp.

[0029] In this preferred embodiment, the internally reflective high-voltage external electrode 7 has a ring-shaped sheet structure interwoven into a mesh. Specifically, the ring-shaped mesh structure of the internally reflective high-voltage external electrode 7 helps to form a uniform and stable electric field distribution, thereby improving the uniformity and efficiency of the discharge.

[0030] In this preferred embodiment, a coolant pipe 15 is fitted onto the outer ring surface of the internally reflective high-voltage external electrode 7. One end of the coolant pipe 15 is connected to a connecting pipe, an electric valve, a heat exchanger, a water pump, and an expansion tank; the other end of the coolant pipe 15 is connected to a return pipe and an expansion tank. A filter screen is installed inside the return pipe. Specifically, the cross-section of the coolant pipe 15 is annular, meaning that the coolant and the external electrode are separated and do not directly contact each other.

[0031] Furthermore, the insulating outer cylinder 1 is made of insulating material. Specifically, the insulating outer cylinder 1 is made of insulating material, which has excellent electrical insulation properties and can effectively isolate high-voltage electric fields to prevent leakage or breakdown.

[0032] Specifically, the longitudinal section of the sealing caps 2 at both ends of the excimer lamp tube 3 is U-shaped; the lead wire of the inner electrode 6 is sealed to the sealing cap 2 by a T-shaped sealing head 12 and a sealing ring.

[0033] The excimer ultraviolet lamp of this invention is designed with a double-layer columnar structure. We use two glass tubes of different diameters to form the inner and outer bulbs of the excimer ultraviolet lamp. The diameter of the two ends of the outer glass tube is reduced by glass processing technology to create shoulders 11, which are then sealed to the two ends of the inner glass tube, making the inner and outer glass layers coaxial and forming a sealed cavity between the two glass tubes. The air in the cavity is then extracted and filled with an appropriate working gas (the working gas is generally an inert gas, or a mixture of inert gas and halogen elements, such as Cl, Ar, Xe, etc.), thus constructing the main structure of the excimer ultraviolet lamp.

[0034] In addition, a conductive reflective layer (internal reflective high-voltage external electrode 7) is applied to the 360-degree circumference of the excimer lamp's outer bulb, with the reflective surface of the layer facing inward toward the axis of the excimer lamp. The reflective layer can be made of metals such as silver or chromium, or it can be made of mirror-finished stainless steel or aluminum sheets. A spiral internal electrode is arranged inside the excimer lamp's inner tube, with the outer cylindrical surface of the internal electrode tightly attached to the inner wall of the inner tube. Sufficient gaps are reserved between the spirals of the internal electrodes, allowing the ultraviolet light emitted during excimer lamp operation to pass through these gaps into the cylindrical cavity formed by the inner wall of the inner tube.

[0035] In summary, this invention connects the conductive reflective layer on the outer circumference of the excimer lamp to one of the output terminals of the excimer lamp power supply, and connects the spiral inner electrode of the excimer lamp to the other output terminal of the excimer lamp power supply and grounds it, ensuring that it is always at zero potential. Thus, when the input power is connected to the input terminal of the excimer lamp, the excimer lamp begins to operate.

[0036] When the excimer lamp starts working, it emits ultraviolet light. At this time, some of the ultraviolet light emitted from the working chamber of the lamp tube will be directed into the columnar space inside the inner tube. Due to the effect of the outer reflective layer, the light originally directed towards the outside of the excimer lamp will also be reflected into the columnar space inside the inner tube. This concentrates all the ultraviolet energy emitted by the lamp tube into the narrow space inside the inner tube, resulting in a significant increase in its ultraviolet radiation intensity.

[0037] In this way, without increasing the power of the ultraviolet lamp, we achieve a much higher ultraviolet radiation intensity inside the tube than outside. When the liquid or gas to be treated flows through the excimer lamp's inner tube after passing through a sealed structure, the high ultraviolet radiation intensity requirements of some special photochemical reactions or processing techniques can be met. Because this method can meet process requirements without increasing the power of the ultraviolet lamp, the size and cost of the equipment are significantly reduced. Furthermore, the elimination of the need for additional heat dissipation simplifies the equipment's structure.

[0038] Because the internal electrode of the excimer lamp is grounded, it maintains zero potential during operation, ensuring safety. Furthermore, when the object to be processed is a liquid with a certain degree of conductivity, we can even eliminate the spiral internal electrode inside the inner tube, allowing the liquid to directly conduct to the output terminal of the excimer power supply and ground. In this case, as the liquid flows through the inner tube of the excimer lamp, it itself constitutes the internal electrode of the lamp. This makes the structure of the processing equipment simpler and the sealing process more convenient.

[0039] Working principle: When the excimer processor starts working, the operator uses an external control switch to turn on the inner electrode 6 and the inner reflective high-voltage outer electrode 7. At this time, a portion of the ultraviolet light emitted from the working chamber of the excimer lamp tube 3 will be directed into the cylindrical space inside the inner tube. Due to the effect of the reflector plate 4, the light originally directed towards the outside of the excimer lamp will also be reflected into the cylindrical space inside the inner tube. This concentrates all the ultraviolet energy emitted by the lamp tube into the narrow space inside the excimer lamp tube 3, thereby enhancing the ultraviolet radiation intensity. In this way, the ultraviolet radiation intensity can be increased without increasing the power of the ultraviolet lamp tube.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
