Description

Technical Field

[0001] This invention belongs to the field of photocatalytic degradation technology, specifically relating to an attapulgite-based VOCs photocatalytic degradation component. Background Technology

[0002] Volatile organic compounds (VOCs) are organic compounds with high vapor pressure and easy volatilization under normal temperature and pressure. They are commonly found in paints, coatings, adhesives, cleaning agents, furniture, and building materials. Short-term exposure to VOCs can cause irritation to the eyes, nose, and throat, as well as symptoms such as headache, nausea, and fatigue. Long-term exposure may damage the liver, kidneys, and nervous system. Some VOCs, such as benzene and formaldehyde, have been proven to be carcinogenic, and high concentrations may also exacerbate asthma and trigger respiratory diseases.

[0003] Existing VOCs photocatalytic degradation devices often fail to fully utilize the light source, with some of the emitted light unusable for photocatalysis. For example, Chinese patent CN221492064U discloses a photocatalytic VOCs degradation reaction chamber that uses an external xenon lamp as the light source. However, some of the light emitted by the xenon lamp cannot reach the interior of the reaction chamber for use, resulting in significant energy waste if used for long-term indoor air purification. Therefore, there is a need for an attapulgite-based VOCs photocatalytic degradation component. Summary of the Invention

[0004] To address the aforementioned issues, this invention discloses an attapulgite-based VOCs photocatalytic degradation component.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A photocatalytic degradation component for VOCs based on attapulgite comprises a lower spherical shell and an upper spherical shell joined together and sharing a common center. A temperature-controlled cavity is provided between the inner and outer shells of both the lower and upper spherical shells, and the temperature-controlled cavities of the lower and upper spherical shells are interconnected. A reflective layer is provided on the inner wall of the inner shell of both the lower and upper spherical shells. A rod seat is threadedly connected to the top of the upper spherical shell, and an LED bead located at the center of the shell is installed at the bottom of the rod seat. An air inlet seat is threadedly connected to the bottom of the lower spherical shell, and a bracket is installed on the top of the air inlet seat. Several arc-shaped frames extend from the bracket, and several vertically connected catalyst frames are installed on the vertical rods of each arc-shaped frame. Several vertically connected catalyst frames are installed on the main shaft of the bracket. Several annularly distributed through holes in the air inlet seat leading to the inner cavity of the spherical shell are all connected to helical tubes, and all helical tubes share a common helical axis. An air outlet pipe is connected to the rod seat through a through hole connecting the inner cavity of the spherical shell to the outside.

[0007] As a preferred embodiment of this utility model, both the lower and upper spherical shells have an outer tube extending from their outer shells to communicate with the temperature control cavity.

[0008] As a preferred embodiment of this utility model, the inner and outer shells of the upper spherical shell extend out with annular protrusions that are respectively inserted into two annular grooves of the lower spherical shell.

[0009] As a preferred embodiment of this invention, a sealing ring is placed in each of the two annular grooves.

[0010] In a preferred embodiment of this invention, the flange ring between the lower and upper spherical shells is connected together by a number of connecting bolts and nuts.

[0011] As a preferred embodiment of this utility model, the center of all the arc-shaped frames is located at the center of the spherical shell.

[0012] As a preferred embodiment of this utility model, the catalyst frame is provided with a screw at the bottom and a screw hole adapted to the screw at the top. The catalyst frames are connected to each other by screws and screw holes, and the support is connected to the screw thread hole of the catalyst frame. Each catalyst frame has a shaft extending out of several blades with attached attapulgite-based photocatalysts.

[0013] As a preferred embodiment of this utility model, the bottom of the bracket is threadedly connected to the air intake seat.

[0014] As a preferred technical solution of this utility model, the outer shell of the lower spherical shell is fixedly connected to a base, and the bottom ring of the base is provided with several through holes.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The light source of this application is set at the center of the spherical shell. A large gap is left between the catalytic frames closest to the light source to allow the light from the light source to pass through. The light passing through the gap between the catalytic frames is continuously reflected by the reflective layer on the inner wall of the inner shell to illuminate all the catalytic frames from multiple angles as much as possible, so that the light emitted by the light source is used for photocatalysis as much as possible, which has a high utilization rate of electrical energy and is energy-saving and environmentally friendly.

[0017] 2. The exhaust gas of this application is blown out through a spiral tube. The spirally rising exhaust gas is dispersed and contacts the catalytic frame inside the spherical shell. When the exhaust gas is irradiated by light, it reacts and degrades with the catalytic frame. The number of catalytic frames can be flexibly set, and the support and catalytic frame are installed with threads, which is convenient for installation. Attached Figure Description

[0028] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0029] Please see Figure 1-7An attapulgite-based VOCs photocatalytic degradation component includes a lower spherical shell 1 and an upper spherical shell 2 joined together and concentric, forming a single integral spherical shell. A temperature-controlled cavity is provided between the inner and outer shells of both the lower and upper spherical shells 1 and 2, and these cavities are interconnected. A temperature-controlled liquid flows within the temperature cavity, maintaining a suitable photocatalytic temperature within the spherical shell. A reflective layer is provided on the inner wall of both the lower and upper spherical shells 1 and 2. A rod seat 3 is threadedly connected to the top of the upper spherical shell 2, and an LED 4 is mounted at the bottom of the rod seat 3, positioned at the center of the spherical shell. The power supply wire of the LED 4 is concealed within the rod of the rod seat 3 and extends to the outside of the spherical shell. The LED 4 provides illumination for the photocatalytic degradation of VOCs. An air inlet seat 7 is threadedly connected to the bottom of the lower spherical shell 1, and a bracket 9 is mounted on the top of the air inlet seat 7. The support 9 extends into several arc-shaped frames, and each arc-shaped frame has several vertically connected catalyst frames 10 mounted on its vertical rod. The main shaft of the support 9 also has several vertically connected catalyst frames 10 mounted on it. The sparseness and number of the catalyst frames 10 must ensure that the catalyst frames 10 are directly or indirectly illuminated by the light from the LED beads 4 after installation. Several annularly distributed through holes in the air inlet seat 7 leading to the inner cavity of the spherical shell are all connected to spiral tubes 8, and all spiral tubes 8 share a common spiral axis. The gas blown out by all spiral tubes 8 spirals upwards, causing the gas initially entering the spherical shell to disperse and contact the catalyst frames 10. The rod seat 3 has an outlet pipe 5 connected to the through hole connecting the inner cavity of the spherical shell to the outside.

[0030] The flange rings between the lower spherical shell 1 and the upper spherical shell 2 are connected together by several connecting bolts and nuts 11, so that the temperature control chambers of the lower spherical shell 1 and the upper spherical shell 2 are connected together, and the spherical shell formed by the lower spherical shell 1 and the upper spherical shell 2 has a spherical inner cavity.

[0031] The inner and outer shells of the upper spherical shell 2 extend into two annular grooves 101, which are respectively inserted into the lower spherical shell 1. A sealing ring 6 is placed in each of the two annular grooves 101. The annular protrusions compress the sealing ring 6 to enhance the sealing performance of the temperature control cavity and the spherical inner cavity.

[0032] Both the lower spherical shell 1 and the upper spherical shell 2 have external connecting pipes extending from their outer shells to communicate with the temperature control chamber. The two external connecting pipes are respectively connected to the two ends of the circulating temperature control liquid pipeline, so that the temperature control liquid circulates in the temperature control chamber during use.

[0033] The center of all the arc-shaped frames is located at the center of the spherical shell. A screw is provided at the bottom of the catalyst frame 10 and a screw hole adapted to the screw is provided at the top. The catalyst frames 10 are connected to each other via screws and screw holes, and the support 9 is connected to the screw thread hole of the catalyst frame 10. Several blades with attached attapulgite-based photocatalysts extend from the shaft of each catalyst frame 10.

[0034] The bottom of the bracket 9 is threaded to the air intake seat 7. When using it, first tighten the air intake seat 7 to the bottom of the lower ball shell 1, and then screw the bracket 9 onto the air intake seat 7.

[0035] The lower spherical shell 1 is fixedly connected to a base 12, and the bottom ring of the base 12 is provided with several through holes. The through holes of the base 12 are used for bolts to pass through, so that the base 12 can be installed and fixed.

[0036] Working principle:

[0037] In use, first tighten the intake seat 7 to the bottom of the lower spherical shell 1, then screw the bracket 9 onto the top of the intake seat 7. Next, install several catalytic converter holders 10 on the bracket 9, and install the rod seat 3 on the top of the upper spherical shell 2. Use several connecting bolts and nuts 11 to assemble the lower spherical shell 1 and the upper spherical shell 2 together. The LED 4 is located at the center of the spherical shell. A large gap is left between the catalytic converter holders 10 closest to the LED 4 to allow the light from the LED 4 to pass through. The light passing through the gap between the catalytic converter holders 10 is continuously reflected by the reflective layer on the inner wall of the inner shell to illuminate all the catalytic converter holders 1 from multiple angles as much as possible. 0. Then, the two external pipes of the spherical shell are connected to the two ends of the circulating temperature-controlled liquid pipeline, so that the temperature-controlled liquid circulates in the temperature-controlled cavity of the spherical shell during use, and the inner cavity of the spherical shell maintains a suitable photocatalytic reaction temperature. Then, the air inlet 7 is connected to the exhaust gas pipeline containing VOCs, and the exhaust pipe 5 is connected to other exhaust gas treatment devices. When the exhaust gas containing VOCs enters the air inlet 7, the exhaust gas is blown out through the spiral pipe 8. The spirally rising exhaust gas is dispersed and contacts the catalytic frame 10 in the spherical shell. When the exhaust gas is irradiated by the light, it reacts with the catalytic frame 10 and degrades. After degradation, the VOCs gas is discharged through the exhaust pipe 5.

For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
