[0004] The aforementioned patent describes a photocatalytic waste gas treatment device, in which the photocatalytic unit is typically a UV lamp panel. The UV lamp panel is one of the core components of the photocatalytic waste gas treatment device. The luminous efficiency of the lamp tube gradually decreases with the increase of usage time, and the ultraviolet intensity weakens, resulting in a decrease in catalytic effect. Furthermore, the dirt accumulated on the surface of the lamp tube during use also affects the transmittance of ultraviolet light, thereby affecting the catalytic effect. Since the UV lamp panel is usually installed on the inner wall of the catalytic chamber, it is inconvenient to repair when there is a malfunction, which affects the subsequent maintenance work. Therefore, we propose a photocatalytic waste gas treatment device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a photocatalytic waste gas treatment device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a photocatalytic waste gas treatment device, comprising a catalytic chamber, an air inlet, an exhaust outlet, a control panel, control lines, and an external catalytic device.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features an external catalytic device located in the center of the front of the catalytic converter. When replacing the UV lamp panel, first disconnect the control circuit from the terminal block. Then, disassemble the hinge shaft from the inside of the hinge sleeve upwards, allowing the UV lamp panel to be removed and replaced together. During installation, insert the hinge shaft from top to bottom into the inside of the hinge sleeve, establishing a hinge connection between the light source panel and the mounting opening. Then, flip the light source panel and close it inside the mounting opening, allowing the UV lamp panel to be movably inserted into the catalytic converter through the mounting opening. Next, open the spring lock so that its locking tongue engages with the locking hole, locking the light source panel inside the mounting opening. Finally, connect the control circuit to the terminal block to establish an electrical connection between the UV lamp panel and the control panel, thus completing the installation and replacement of the UV lamp panel.

Detailed Implementation

[0021] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0022] Please see Figure 1 This utility model provides a photocatalytic waste gas treatment device, including a catalytic box 1, an air inlet 2, an exhaust outlet 3, a control panel 4, a control line 5, and an external catalytic device 6. The catalytic box 1 has an air inlet 2 on the left side and an exhaust outlet 3 on the right side. The control panel 4 is installed on the top edge of the front of the catalytic box 1. The control line 5 is laid horizontally on the upper part of the front of the catalytic box 1. The external catalytic device 6 is set in the middle of the front of the catalytic box 1.

[0023] Please see Figure 2-4 This utility model provides a photocatalytic waste gas treatment device. The external catalytic device 6 includes an inner mounting port 61, an outer mounting port 62, a hinge sleeve 63, a light source panel 64, a hinge shaft 65, a UV lamp panel 66, a terminal block 67, a spring lock 68, and a lock hole 69. The inner mounting port 61 is located in the middle of the front wall of the catalytic chamber 1, and the outer mounting port 62 is located in the middle of the front of the outer side of the catalytic chamber 1. The outer mounting port 62 corresponds to and is connected to the inner mounting port 61. At least two hinge sleeves 63 are screwed and installed on the right side of the outer mounting port 62. At least two hinge shafts 65 are welded to the right side of the light source panel 64. The hinge shafts 65 are movably inserted into the inner side of the hinge sleeves 63 from top to bottom, so that the light source panel 64 is hinged to the right side of the outer mounting port 62. Rotating, the light source panel 64 can be flipped and closed into the inner side of the mounting port 62. A UV lamp plate 66 is installed on the back of the light source panel 64. The UV lamp plate 66 is movably embedded into the catalytic chamber 1 through the mounting port 61. A terminal block 67 is provided on the side of the front of the light source panel 64. The terminal block 67 establishes an electrical connection with the light source panel 64. The control circuit 5 is connected to the terminal block 67 through the end circuit connector, thereby establishing an electrical connection between the UV lamp plate 66 and the control panel 4. A spring lock 68 is installed on the left side wall of the mounting port 62. A lock hole 69 is opened on the left side of the light source panel 64. The locking tongue on the side of the spring lock 68 can be engaged with the lock hole 69, thereby locking the light source panel 64 inside the mounting port 62 and preventing it from flipping off on its own.

[0024] To further explain, a sealing gasket is laid on the inner wall of the mounting port 62. The sealing gasket is ≥2.5mm thick and can fill the gap between the mounting port 62 and the light source panel 64 to ensure the airtightness of the mounting port 62.

[0025] To further explain, the maximum rotation angle between the hinge shaft 65 and the hinge sleeve 63 is 120 to 180 degrees, so that the light source panel 64 has a sufficiently large opening angle, so that the UV lamp plate 66 can be inspected after the light source panel 64 is opened.

[0026] To further explain, the thickness of the UV lamp plate 66 is at least 10 mm greater than the depth of the mounting opening 61, so as to ensure that the UV lamp plate 66 can pass through the mounting opening 61 and be installed inside the catalytic converter 1.

[0027] To further explain, the hinge sleeve 63 has no fewer than two screws, and the number of hinge shafts 65 is the same as that of the hinge sleeve 63, to ensure the connection strength between the light source panel 64 and the mounting port 62.

[0028] Please see Figure 5 This utility model provides a photocatalytic waste gas treatment device. A threaded hole 610 is provided in the middle of the bottom end of the hinge shaft 65. A limiting cap 611 is sleeved on the bottom end of the hinge shaft 65. A screw 612 is welded to the bottom surface of the inner side of the limiting cap 611. The screw 612 is threadedly connected to the inner side of the threaded hole 610. The outer diameter of the limiting cap 611 is larger than that of the hinge sleeve 63, thereby restricting the hinge shaft 65 from disengaging from the inner side of the hinge sleeve 63 and ensuring installation stability.

[0029] The working principle is as follows:

[0030] First, when using it, operate the control panel 4 to start the UV lamp panel 66, and then put the waste gas mixed with the catalyst into the catalytic chamber 1 through the air inlet 2. Under the ultraviolet light environment, the harmful substances in the waste gas are converted into harmless substances through photocatalytic reaction, thereby achieving waste gas purification. The purified gas is then discharged from the catalytic chamber 1 through the exhaust port 3.

[0031] Secondly, by setting an external catalytic device 6 in the center of the front of the catalytic chamber 1, the dirt accumulated on the surface of the UV lamp plate 66 will affect the transmittance of ultraviolet rays, thus affecting the catalytic effect. When it is necessary to perform maintenance on the UV lamp plate 66, simply unlock the spring lock 68 so that its locking tongue leaves the lock hole 69, thereby releasing the lock between the light source panel 64 and the mounting port 62. The light source panel 64 can be flipped outward to open, and the UV lamp plate 66 on the back of the light source panel 64 can be inspected and maintained. The operation is convenient.

[0032] Third, the luminous efficiency of the UV lamp panel 66 will gradually decrease with the increase of usage time, and the ultraviolet intensity will weaken, resulting in a decrease in catalytic effect. When it is necessary to replace the UV lamp panel 66, first disconnect the connection between the control line 5 and the terminal block 67, then unlock the spring lock 68 and flip the light source panel 64 outward to open it. Then unscrew the limit cap 611 from the bottom end of the hinge shaft 65, so that the hinge shaft 65 can be disassembled upward from the inside of the hinge sleeve 63. The UV lamp panel 66 can then be disassembled and replaced together with the UV lamp panel 66. During installation, insert the hinge shaft 65 into the inside of the hinge sleeve 63 from top to bottom, so that the light... The source panel 64 is hinged to the mounting port 62. Then, the source panel 64 is flipped and closed into the inner side of the mounting port 62, so that the UV lamp plate 66 is movably embedded into the catalytic converter 1 through the mounting port 61. Then, the spring lock 68 is opened so that its locking tongue engages with the locking hole 69, locking the source panel 64 inside the mounting port 62. Finally, the control line 5 is plugged into the terminal block 67 to establish an electrical connection between the UV lamp plate 66 and the control panel 4, thereby completing the installation and replacement of the UV lamp plate 66. The installation and replacement operation can be completed outside the catalytic converter 1, which is convenient and facilitates the development of subsequent maintenance work.

[0033] Fourth, by setting a limiting cap 611 at the bottom of the hinge shaft 65, after the hinge shaft 65 and the hinge sleeve 63 are inserted, the limiting cap 611 is screwed into the inside of the threaded hole 610 through the screw 612 until the limiting cap 611 is sleeved on the bottom of the hinge shaft 65. The limiting cap 611 can restrict the hinge shaft 65 from disengaging from the inside of the hinge sleeve 63, ensuring installation stability.
