Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an adjustable ultraviolet photocatalytic reaction device for wastewater disinfection. Background Technology

[0002] Ultraviolet (UV) sterilization water treatment is currently recognized worldwide as a green sterilization and disinfection method. The sterilization and disinfection function of UV light has purely physical characteristics, unlike other chemical sterilization and disinfection methods. It will not cause secondary pollution to the physical environment or change the chemical or physical properties of the object.

[0003] Traditional photocatalytic reactors typically use fixed lamps. When the quality of the wastewater to be treated changes, such as turbidity and color, the fixed spatial distribution of light intensity is difficult to adapt to dynamic operating conditions, which can lead to unstable disinfection effects or energy waste.

[0004] Therefore, to address the above issues, an adjustable ultraviolet photocatalytic reaction device for wastewater disinfection can be designed. Through an adjustable lamp installation mechanism, the spacing between the lamps can be freely adjusted according to the water quality of the wastewater being treated, dynamically optimizing the spatial distribution of the ultraviolet light field. Under the premise of ensuring disinfection effect, it can achieve precise matching between light intensity and pollution load. This dynamic control mechanism can improve energy utilization efficiency, thereby constructing an efficient, energy-saving, and stable ultraviolet disinfection process system. Utility Model Content

[0005] To overcome the problem that traditional photocatalytic reactors typically use fixed lamp designs, the fixed spatial distribution of light intensity is difficult to adapt to dynamic operating conditions when the quality of the wastewater to be treated changes, such as turbidity and color, which can lead to unstable disinfection effects or energy waste.

[0006] The technical solution of this utility model is as follows: an adjustable ultraviolet photocatalytic reaction device for wastewater disinfection, including a treatment tank, an installation mechanism, and lamps. The installation mechanism includes a mounting frame, casters, sliders, and a scissor-folding frame. The mounting frame is set above the treatment tank, and multiple sets of mounting frames are provided. Sliders are slidably connected to the periphery of the mounting frame. The scissor-folding frame is hinged between the sliders on the side walls of two adjacent sets of mounting frames. The linkage connection of multiple sets of mounting frames is realized through the synergistic action of the scissor-folding frame and the sliders. Two sets of casters are fixedly installed at the lower end of each set of mounting frames. Two sets of guide rails are fixedly installed at the upper end of the treatment tank. The casters are embedded in the guide rails to form a guide moving pair. Multiple sets of lamps are provided at the lower end of each set of mounting frames.

[0007] Preferably, the lamps are installed using mounting brackets, and the lamps extend into the treatment tank to emit ultraviolet light, thereby disinfecting the wastewater inside the tank. A variable-pitch connection structure is formed by the mechanical cooperation of a scissor-type folding bracket and a slider. Combined with a linear motion pair consisting of casters and guide rails, the distance between adjacent mounting brackets can be infinitely adjusted, thereby adjusting the spacing between the lamps. The spatial distribution of the ultraviolet light field can be dynamically optimized according to the water quality of the treated wastewater, achieving precise matching between light intensity and pollution load while ensuring disinfection effect, effectively reducing energy waste.

[0008] Preferably, multiple sets of external threaded mounting sleeves are fixedly installed at the lower end of the mounting bracket, and the external threaded mounting sleeves are located on the periphery of the lamp tube.

[0009] Preferably, the lamp tube is provided with a transparent cover, the opening of which is provided with an internal thread, and the transparent cover is fitted around the external threaded mounting sleeve.

[0010] Preferably, two sets of positioning brackets are fixedly installed inside the treatment tank, and catalytic plates are slidably connected inside the positioning brackets. The positioning brackets and lamp tubes are arranged alternately.

[0011] Preferably, the outer surface of the catalytic plate is coated with a catalyst coating, and the side wall of the catalytic plate has a communication port.

[0012] Preferably, one end of the treatment tank is connected to an inlet pipe, and the other end of the treatment tank is connected to an outlet pipe, with the height of the inlet pipe being lower than the height of the outlet pipe.

[0013] As a preferred option, a set of solenoid valves is installed at one end of both the inlet and outlet water pipes.

[0014] The beneficial effects of this utility model are:

[0015] Through the linear motion pair formed by the casters and guide rails at the lower end of the mounting frame, the mounting frame can move linearly according to the water quality of the wastewater to be treated, through the cooperation of the slider and the scissor-type folding frame. This allows for stepless adjustment of the distance between adjacent mounting frames, thereby adjusting the distance between the lamps. The above steps can be repeated as needed to place several sets of mounting mechanisms, enabling free adjustment of the lamp spacing and dynamically optimizing the spatial distribution of the ultraviolet light field. This ensures precise matching between light intensity and pollution load while maintaining disinfection effectiveness, effectively reducing energy waste. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of an adjustable ultraviolet photocatalytic reaction device for wastewater disinfection, comprising a treatment tank 1, an installation mechanism, and lamps 3. The installation mechanism includes a mounting frame 2, casters 201, sliders 202, and a scissor-folding frame 203. The mounting frame 2 is positioned above the treatment tank 1, and multiple sets of mounting frames 2 are provided. Sliders 202 are slidably connected to the periphery of the mounting frame 2. The scissor-folding frame 203 is hinged between the sliders 202 on the side walls of two adjacent sets of mounting frames 2. The synergistic action of the scissor-folding frame 203 and the sliders 202 enables the linkage connection of multiple sets of mounting frames 2. Two sets of casters 201 are fixedly installed at the lower end of each set of mounting frames 2. Two sets of guide rails 101 are fixedly installed at the upper end of the treatment tank 1, and the casters 201 are embedded in the guide rails 101 to form a guiding moving pair. Multiple sets of lamps 3 are provided at the lower end of each set of mounting frames 2. The lamps 3 are installed by setting the mounting frame 2. The lamp tube 3 extends into the interior of the treatment tank 1 to emit ultraviolet light, thereby disinfecting the sewage inside the treatment tank 1. By setting up a scissor-type folding frame 203 and a slider 202 to form a variable-pitch connection structure, combined with the linear motion pair formed by the caster 201 and the guide rail 101, the stepless adjustment function of the distance between adjacent mounting frames 2 can be realized, thereby adjusting the distance between the lamp tubes 3. According to the water quality of the treated sewage, the spatial distribution of the ultraviolet light field can be dynamically optimized, and the light intensity and pollution load can be precisely matched while ensuring the disinfection effect, effectively reducing energy waste.

[0024] Please see Figure 3 In this embodiment, multiple sets of external threaded mounting sleeves 301 are fixedly installed at the lower end of the mounting bracket 2. The external threaded mounting sleeves 301 are located around the lamp tube 3. A transparent cover 302 is provided around the lamp tube 3. An internal thread 303 is provided at the opening of the transparent cover 302. The transparent cover 302 is fitted around the external threaded mounting sleeves 301. By providing the transparent cover 302, the lamp tube 3 can be shielded and protected. By providing the internal thread 303, the transparent cover 302 and the external threaded mounting sleeves 301 can be easily fixed by threaded connection, which facilitates the disassembly and cleaning of the transparent cover 302.

[0025] Please see Figure 1 and Figure 2In this embodiment, two sets of positioning brackets 401 are fixedly installed inside the treatment tank 1. Catalytic plates 402 are slidably connected inside the positioning brackets 401. The positioning brackets 401 and lamp tubes 3 are arranged alternately. The outer surface of the catalytic plates 402 is coated with a catalyst coating 403, and a communication port 404 is provided on the side wall of the catalytic plates 402. By setting the positioning brackets 401 to install the catalytic plates 402, the catalytic plates 402 and lamp tubes 3 are arranged alternately, ensuring uniform coverage of the photocatalytic reaction area. The catalyst coating 403 around the catalytic plates 402 provides a catalytic effect for the wastewater treatment reaction. By setting the connecting port 404, the catalytic plate 402 can be prevented from isolating the sewage in the treatment tank 1. One end of the treatment tank 1 is connected to the inlet pipe 501, and the other end of the treatment tank 1 is connected to the outlet pipe 502. The height of the inlet pipe 501 is lower than the height of the outlet pipe 502. A set of solenoid valves 6 is set at one end of both the inlet pipe 501 and the outlet pipe 502. By setting the solenoid valves 6, the inlet and outlet water of the treatment tank 1 can be controlled. The height of the inlet pipe 501 being lower than the outlet pipe 502 can effectively increase the retention time of the input sewage in the treatment tank 1, ensuring that the sewage reaction and disinfection are sufficient.

[0026] During operation, the catalytic plate 402 is first installed inside the treatment tank 1 using the positioning bracket 401, and the entire installation mechanism is placed above the treatment tank 1. The light at the lower end of the mounting frame 2 is inserted into the treatment tank 1 and staggered with the catalytic plate 402 to ensure uniform coverage of the photocatalytic reaction area. At the same time, the linear motion pair formed by the casters 201 and the guide rail 101 at the lower end of the mounting frame 2 can be used to move the mounting frame 2 linearly through the cooperation of the slider 202 and the scissor folding frame, depending on the water quality of the wastewater to be treated. This allows the mounting frame 2 to move linearly through the cooperation of the casters 201 and the guide rail 101, realizing the stepless adjustment function of the distance between adjacent mounting frames 2, thereby adjusting the distance between the lamp tubes 3. The above steps can be repeated according to the actual situation to place several sets of installation mechanisms to achieve free adjustment of the distance between the lamp tubes 3, dynamically optimize the spatial distribution of the ultraviolet light field, and achieve precise matching of light intensity and pollution load while ensuring the disinfection effect, effectively reducing energy waste.

[0027] The inlet and outlet water of the treatment tank 1 can be controlled by the solenoid valve 6. The height of the inlet pipe 501 is lower than that of the outlet pipe 502, which can effectively increase the retention time of the input sewage in the treatment tank 1 and ensure that the sewage reaction and disinfection are sufficient.

[0028] After the sewage has been treated for a period of time, the installation mechanism can be removed from the treatment tank 1. Utilizing the threaded connection between the transparent cover 302 and the external threaded mounting sleeve 301, the transparent cover 302 can be easily disassembled and cleaned.

[0029] Through the above steps, a variable-pitch connection structure is formed by the mechanical cooperation of the scissor-type folding frame 203 and the slider 202. Combined with the linear motion pair formed by the caster 201 and the guide rail 101, the stepless adjustment function of the distance between adjacent mounting frames 2 can be realized. The distance between the lamp tubes 3 can be freely adjusted according to the water quality of the wastewater to be treated, and the spatial distribution of the ultraviolet light field can be dynamically optimized. This solves the problem that the lamp tubes 3 of traditional photocatalytic reactors are usually designed with a fixed type. When the water quality of the wastewater to be treated changes, such as turbidity and color, the fixed spatial distribution of light intensity is difficult to adapt to the dynamic working conditions, which will lead to unstable disinfection effect or energy waste.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
