Description

TECHNICAL FIELD

[0001] The utility model belongs to the waste / sewage treatment in the photocatalysis technical field relates to the photocatalyst optical fiber - micro - bubble oxygen supply integrated device for waste / sewage purification. BACKGROUND

[0002] Traditional photocatalytic process has problems of uneven dispersion of catalyst, difficulty in recycling, low light energy utilization efficiency and unstable photocatalytic efficiency, which limits its widespread application in practical application. Fixing the powder photocatalyst on a certain carrier is one of the ways to solve the problems of uneven distribution and difficulty in recycling of photocatalyst. The light guide fiber mainly uses optical fiber as the light guide carrier, so that the light reaches the designated illumination area, improves the light energy utilization rate, and realizes accurate light control. Coating the powder photocatalyst on the surface of the light guide fiber combines the above two ideas, which can not only solve the problem of photocatalyst immobilization, but also improve the light utilization efficiency. On the other hand, the photocatalytic technology used in water purification is affected by environmental factors such as light, water quality and temperature, resulting in unstable catalytic activity. Therefore, it is necessary to combine photocatalysis with other water treatment technologies to ensure the stability of water purification efficiency. The micro-bubble water treatment technology introduces bubbles with a diameter of less than 50 microns into the water, and treats the pollutants in the water through the physical effects (such as improving the oxidation-reduction capacity and improving the settling velocity of suspended solids) and chemical effects (such as enhancing the oxidation effect and improving the sludge structure) of the bubbles. The combination of photocatalytic technology and micro-bubble technology realizes the mixing and stirring of the water system during the introduction of bubbles, improves the mass transfer and diffusion of pollutants, and strengthens the photocatalytic efficiency; at the same time, the oxygen is converted into superoxide free radical (·O2 - ) in the photocatalytic process to further degrade the pollutants, making up for the instability of the photocatalytic process.

[0039] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0040] Example 1

[0041] This utility model relates to an integrated optical fiber-microbubble oxygen supply device for photocatalyst purification of waste / sewage. The device comprises an adjustable multi-band lamp source system, an optical fiber system loaded with photocatalyst, a microbubble oxygen supply pump system, and a support frame.

[0042] Example 2

[0043] like Figure 1As shown, the support frame includes an annular upper positioning PPS (polyphenylene sulfide) plastic sheet 4 (for fixing the snap-fit ​​assembly A3) and an annular lower positioning PPS plastic sheet 9 (for fixing the snap-fit ​​assembly B8) arranged parallel to each other vertically. The upper positioning PPS plastic sheet 4 and the lower positioning PPS plastic sheet 9 are connected by four vertically arranged support columns 6. The support columns 6 are cylindrical PPS plastic, and the four support columns 6 are evenly arranged. Between two adjacent support columns 6, a number of photocatalytic coated optical fibers 5 (for the degradation of pollutants in water by the supported photocatalyst) are arranged vertically. A number of snap-fit ​​assemblies A3 are evenly arranged on the upper positioning PPS plastic sheet 4 for emitting upper light to activate the photocatalyst and fixing the upper part of the optical fiber. A number of snap-fit ​​assemblies B8 are evenly arranged on the lower positioning PPS plastic sheet 9 for emitting lower light to activate the photocatalyst and fixing the lower part of the optical fiber.

[0044] The support frame houses a pump source 7 (for providing power for water circulation), and a pump source motor 2 (for providing power to the pump source) is connected above the pump source 7. The pump source motor 2 is connected to the controller via a wire 10, and a waterproof and anti-slip rubber sleeve B11 is provided at the connection between the pump source motor 2 and the wire 10 to prevent water from entering the pump source motor 2 and the wire 10.

[0045] Example 3

[0046] like Figure 2 As shown, the pump source 7 includes a hollow double-sided impeller housing 16. A ring of uniformly spaced microbubble transmission holes 17 is provided at the center of the double-sided impeller housing 16 for the transmission of microbubble generation. A fixing cover 14 is provided above the double-sided impeller housing 16, which can fix the pump source motor 2. An opening is provided at the center of the bottom of the fixing cover 14, which communicates with the waterproof and anti-slip rubber ring A1. Figure 3 As shown, the fixed cover 14 has a threaded opening at the center of its bottom. The fixed cover 14 is connected to the pump shaft fixing sleeve 22 via this thread. To ensure that gas can smoothly enter the double-sided impeller area from the one-way valve 23, the thread height in the pump shaft fixing sleeve 22 is half the height of the sleeve. This ensures that the height of the fixed cover 14 is half the height of the pump shaft fixing sleeve 22, preventing the fixed cover 14 from obstructing the one-way valve 23. A pump source motor 2 is located above the fixed cover 14, and the pump source motor 2 and the fixed cover 14 are an integral structure. A packing area is installed below the double-sided impeller area housing 16. The packing area includes a packing area housing 18, which has 24 holes B19 on its side (for side oxygenation outlets). This ensures that water can smoothly enter the packing area under the drive of the impeller area, while preventing the packing from leaking into the water.

[0047] Example 4

[0048] like Figure 3As shown, the bottom of the double-sided impeller area housing 16 is provided with a waterproof and anti-slip rubber ring B25, and the top of the double-sided impeller area housing 16 is provided with a cover plate 24. A pump shaft fixing sleeve 22 is provided at the center of the cover plate 24. Two one-way valves 23 are provided on the cover plate 24 for air to enter the double-sided impeller area in one direction. A motor pump shaft 21 is provided at the center of the upper end of the pump shaft fixing sleeve 22. The top end of the motor pump shaft 21 passes through the opening at the center of the bottom of the fixing cover and is directly connected to the pump source motor 2.

[0049] Example 5

[0050] like Figure 4 As shown, inside the double-sided impeller area housing 16, there are coaxially arranged parallel disc-shaped fixing seats A29 (for fixing the upper conical baffle 28) and B30. The upper conical baffle 28 is installed inside fixing seat A29, and oblique guide channels are installed on the conical baffle 28. The number of oblique guide channels depends on the specific water conditions, ranging from 2 to 12, and is used to guide the airflow downwards. Eight fixing plates are provided at the edges of fixing seats A29 and B30, which are used to bond fixing seats A29 and B30 to the inside of the double-sided impeller area housing 16. An opening is provided at the center of the upper conical baffle 28, and at the center of fixing seats A29 and B30, for the motor pump shaft 21 to pass through. An air impeller body 26 is connected to the motor pump shaft 21. Impeller blades 27 are fixed to the air impeller body 26. The number of impeller blades 27 depends on the specific water conditions, ranging from 8 to 16. When the motor pump shaft 21 rotates, the air impeller body 26 and impeller blades 27 rotate with the motor pump shaft 21. Air enters the interior of the double-sided impeller area housing 16 through the one-way valve 23, forming high-pressure gas. A water impeller body 32 is connected to the motor pump shaft 21. Impeller blades 31 (for drawing in water) are fixed to the water impeller body 32. The number of water impeller blades 31 depends on the specific water conditions, ranging from 4 to 8. When the motor pump shaft 21 rotates, the water impeller body 32 (for fixing the impeller blades) and the water impeller blades 31 rotate with the motor pump shaft 21. Water enters the interior from the lower part of the double-sided impeller area housing 16, forming a high-speed water flow.

[0051] Example 6

[0052] like Figure 5 As shown, a lower conical baffle 33 is provided inside the disc-shaped fixed base B30. An inclined guide channel is installed on the lower conical baffle 33. The number of inclined guide channels depends on the specific water conditions and varies from 2 to 12. It is used to guide the water flow upward. An opening is provided in the center of the lower conical baffle 33, and the motor pump shaft 21 passes through the opening.

[0053] like Figure 6As shown, a baffle 34 is installed on the outer shell 18 of the packing area to separate the impeller area and the packing area. The baffle 34 has several holes C35 to ensure that water can enter the impeller area from the packing area, while the packing is stored in the packing area and will not enter the impeller area to damage it. The outer shell 18 of the packing area has 24 holes B19 on its side. The baffle 34 is fitted inside a waterproof and anti-slip rubber ring E60. The waterproof and anti-slip rubber rings B25 in the impeller area and E60 in the packing area have corresponding threads, allowing the double-sided impeller area outer shell 16 and the packing area outer shell 18 to be connected by threads, forming a complete unit. Figure 2 .

[0054] like Figure 7 As shown, the bottom of the outer shell 18 of the packing area is provided with a pump source filter PPS plastic perforated plate 20, with 7 holes D36 below for bottom water circulation, ensuring that the water can smoothly enter the packing area under the drive of the impeller area, while ensuring that the packing will not leak from the packing area into the water.

[0055] like Figure 8 As shown, the internal cavity region of the filler region shell 18 contains filler 37, which is randomly distributed within the filler region for use with the photocatalytic fiber optic system. Figure 10 The size of the packing material is determined by the size of the water circulation holes, and it is generally larger than the size of the water circulation holes.

[0056] like Figure 9 As shown, the side wall of the fixing cover 14 has four evenly spaced holes A15, which can be connected to the fixing post 38. The fixing post 38 is then used to fix the fixing cover 14 to the support frame. The upper positioning PPS plastic sheet 4 has holes corresponding to the four holes A15 on the fixing cover 14, used to fix the fixing post 38. The fixing post 38 is detachable and has threads at both ends. One end of the fixing post 38 is connected to the upper positioning PPS plastic sheet 4, and the other end of the fixing post 38 is connected to the fixing cover 14, thus connecting the upper positioning PPS plastic sheet 4 and the fixing cover 14.

[0057] like Figure 10 As shown, the snap-fit ​​assembly A3 includes an upper light source 39 (for emitting upper light to activate the photocatalyst) and an upper PPS plastic snap-fit ​​40 (for fixing the upper part of the optical fiber), and the snap-fit ​​assembly B8 includes a lower light source 42 and a lower PPS plastic snap-fit ​​41 (for fixing the lower part of the optical fiber). The upper PPS plastic snap-fit ​​40 is installed at the lower part of the upper light source 39, and the lower PPS plastic snap-fit ​​41 is installed at the upper part of the lower light source 42. The upper end of the photocatalyst-coated optical fiber 5 is connected to the upper PPS plastic snap-fit ​​40, and the lower end of the photocatalyst-coated optical fiber 5 is connected to the lower PPS plastic snap-fit ​​41.

[0058] like Figure 11 and 12As shown, the upper light source 39 includes an upper light source housing 43, a waterproof and anti-slip rubber ring C44, and an upper light source LED bead 45. The lower part of the upper light source housing 43 is wrapped by the waterproof and anti-slip rubber ring C44 to prevent water from entering the upper light source and to reinforce the upper light source and the upper PPS plastic (polyphenylene sulfide) buckle. The upper light source housing 43 contains an upper light source LED bead 45, which is used to emit upper light to activate the photocatalyst of the photocatalyst-coated optical fiber 5.

[0059] like Figure 13 As shown, the upper PPS plastic clip 40 includes an upper PPS plastic clip housing 47. The interior of the upper PPS plastic clip housing 47 is a hollow area used to house the upper part of the photocatalyst-coated optical fiber 5. The bottom of the upper PPS plastic clip housing 47 is provided with four upper PPS plastic clip claws 48 for fixing the upper part of the photocatalyst-coated optical fiber. The upper part of the upper PPS plastic clip housing 47 has an upper connection port 46. The inner wall of the upper lamp source 39 is threaded, and the upper connection port 46 is also threaded. The upper lamp source 39 and the upper PPS plastic clip 40 are connected together by threads to form the clip assembly A3.

[0060] like Figure 14 and 15 As shown, the lower light source 42 includes a lower light source housing 50, a waterproof and anti-slip rubber ring D49, and a lower light source LED bead 51. The lower part of the lower light source housing 50 is wrapped by the waterproof and anti-slip rubber ring D49 to prevent water from entering the lower light source and to reinforce the lower light source and the lower PPS plastic buckle. A lower light source LED bead 51 is located in the center of the lower light source housing 50 to emit lower light to activate the photocatalyst of the photocatalyst-coated optical fiber 5.

[0061] like Figure 16 As shown, the lower PPS plastic buckle 41 includes a lower PPS plastic buckle housing 53. The upper part of the lower PPS plastic buckle housing 53 is provided with a lower PPS plastic buckle claw 52 for fixing the lower part of the photocatalyst coated optical fiber. The lower part of the lower PPS plastic buckle housing 53 is provided with a lower connection port 54. The inner wall of the lower lamp source 42 is engraved with threads, and the lower connection port 54 is also engraved with threads. The lower lamp source 42 and the lower PPS plastic buckle 41 can be connected together by threads to form a buckle assembly B8.

[0062] like Figure 17As shown, the control switch 12 panel includes a speed adjustment knob 55, a light wavelength adjustment knob 56, a light intensity adjustment knob 57, a main control switch 58, and an LCD display 59. Knob 55 controls the aeration power of the pump source; knob 56 controls the light wavelength; knob 57 controls the light intensity; knob 58 controls the power supply of the entire system; and knob 59 displays the current system's on / off status, aeration power, light power, and light wavelength. Waterproof and anti-slip sleeves B11 are installed at both ends of the control switch 12. The wire 10 integrates the wiring for the lamp and pump sources, passes through the waterproof and anti-slip sleeves B11, and is integrated inside the control switch 12, with the other end connected to the power supply.

[0063] The adjustable multi-band light source is a light source with adjustable wavelengths and brightness, ranging from 250 to 780 nm. It can generate light in specific wavelengths suitable for the photocatalyst reaction, ensuring the activation efficiency of the photocatalyst. The light source and PPS plastic clips are connected by threads through openings. The combination hole and the upper and lower positioning PPS plastic discs are connected through openings, allowing for easy replacement of light sources with different power or those that are damaged. The photocatalyst-loaded optical fiber system consists of photocatalyst-coated optical fiber 5. The photocatalyst-coated optical fiber 5 includes the optical fiber itself and a photocatalyst coating uniformly coated on its surface. The optical fiber can be either quartz optical fiber or plastic optical fiber, and the photocatalyst is TiO2 / BiOI, which can receive visible or ultraviolet light, thereby exerting an oxidation-reduction reaction and purifying the environment. The photocatalyst coating is applied to the outer layer of the optical fiber using either dip-coating or immersion methods, and can receive visible or ultraviolet light from the end face and sides. The photocatalyst-coated optical fiber 5 is fixed at both ends using upper and lower PPS plastic clips, forming an integrated system with the adjustable multi-band light source system.

[0064] The working process of this utility model's integrated optical fiber-microbubble oxygen supply device for waste / sewage purification is as follows:

[0065] 1) Turn on the main control switch 58. The LCD screen 59 will display numbers, indicating that the system is activated and ready to operate. Adjust the speed adjustment knob 55, the light wavelength adjustment knob 56, and the light intensity adjustment knob 57 according to the current water conditions to set the aeration power, light power, and light wavelength respectively.

[0066] 2) When the speed adjustment knob 55 is turned on, pump source 7 starts, and the microbubble oxygen supply pump system begins to work. Motor 2 then drives... Figure 3The pump source operates in the double-sided impeller area, driving the motor pump shaft 21 to rotate. Air is introduced under negative pressure from the one-way valve 23, contacts the upper conical baffle 28, and is guided by the guide groove on the conical baffle 28 to the microbubble transmission hole 17. Water is drawn in under negative pressure from the packing area holes 19 and 36, passes through hole B35 to the impeller area, contacts the lower conical baffle 33, and the guide groove on the conical baffle 33 guides the water flow to the microbubble transmission hole 17. The special impeller structure inside the microbubble oxygen supply pump ensures that after the gas and water enter the guide wheel... When the microbubble transfer hole 17 is opened, the space shrinks rapidly and the mixing resistance increases, causing kinetic energy to be converted into pressure energy. The pressure increases, the gas solubility increases, and a large amount of air dissolves into the water. After the gas-liquid mixture is output from the microbubble transfer hole 17, the pressure suddenly decreases and the kinetic energy increases as water vapor suddenly enters the large space from the small space. At the same time, the gas dissolved under high pressure is released from the water, generating microbubbles with diameters between tens and hundreds of micrometers. These microbubbles have a large specific surface area and a long residence time, which can effectively improve the oxygen transfer efficiency.

[0067] 3) Packing material 37 can be added to the packing area inside the pump source 7. The packing material can filter large particles or flocculent pollutants and also enrich functional microorganisms to carry out preliminary biodegradation of pollutants.

[0068] 4) When the light wavelength adjustment knob 56 and the light intensity adjustment knob 57 are turned on, Figure 10 The fiber optic assembly begins operation. Adjusting the wavelength adjustment knob 56 and the intensity adjustment knob 57 allows for adjustment of the wavelength and intensity of the multi-band lamp source system. The upper lamp source bead 45 and the lower lamp source bead 51 simultaneously emit light, illuminating the photocatalyst-coated fiber optic 5 from both ends, activating the photocatalyst and initiating photocatalysis. The photocatalyst on the photocatalyst-coated fiber optic 5 degrades water pollutants through oxidation-reduction reactions, synergistically removing water pollutants with the filler 37.

[0069] 5) The water body circulates through the pump source ( Figure 18 When motor 2 operates, water is drawn in through holes C36 and A19. The water passing through the packing layer is filtered and purified by the packing, removing pollutant particles and flocs. The functional microorganisms enriched in the packing degrade some organic matter and ammonia nitrogen. The preliminarily purified water enters the double-sided impeller area through hole B35. Under the action of the double-sided impeller, it forms microbubbles and is ejected from the microbubble transmission hole 17. Under the action of water pressure, it first moves parallel for a period of time, and then moves downward to achieve water flow. Then it comes into contact with the photocatalyst coated optical fiber 5. The ejected water is again purified by the photocatalyst optical fiber system through oxidation and reduction.
