Description

Technical Field

[0001] The utility model relates to the technical field of photocatalytic oxidation, in particular to a photocatalytic oxidation reactor. Background Art

[0002] Photochemical and photocatalytic oxidation are advanced oxidation technologies that have been extensively researched. A photocatalytic reaction is a chemical reaction that occurs under the action of light. A photochemical reaction requires molecules to absorb electromagnetic radiation of a specific wavelength, which stimulates them to produce an excited state. This reaction then undergoes a chemical reaction to generate new substances or to become an intermediate chemical product that triggers a thermal reaction. The activation energy of a photochemical reaction comes from the energy of photons. Photoelectric conversion and photochemical conversion have been very active research areas in the utilization of solar energy.

[0003] Among existing photocatalytic oxidation reactors, for example, CN206897175U describes a photocatalytic oxidation reactor comprising a support, a photocatalytic reaction chamber mounted on the support, and a control chamber. The control chamber comprises a rectangular housing and a top cover, with heat dissipation vents and a line inlet provided on the sides of the rectangular housing. The photocatalytic reaction chamber is a rectangular box comprising an air inlet, an air outlet, an upper bracket, a lower bracket, a UV lamp, a photocatalytic plate, a side door, and a drain outlet. The air inlet is provided with a stainless steel filter. The upper and lower brackets are mounted with parallel, spaced UV lamps and a photocatalytic plate. The side door is located on one side of the rectangular box, parallel to the air inlet and outlet. The drain outlet is located at the bottom of the box. Existing technology only uses spaced lamps, making it difficult to ensure uniform photocatalytic oxidation of each component. Furthermore, filtering through the stainless steel filter results in poor filtration. Utility Model Content

[0004] The purpose of the utility model is to provide a photocatalytic oxidation reactor to solve the technical problems that it is difficult to ensure that the photocatalytic oxidation reaction acts evenly on each component during the use of the current photocatalytic oxidation reactor, and the filtering effect is poor when filtering through a stainless steel filter.

[0005] The present invention is achieved through the following technical solutions:

[0006] A photocatalytic oxidation reactor comprises a catalytic inner cylinder, a first lamp tube, a catalytic oxidation plate, a first lamp ring plate and a catalytic outer cylinder;

[0007] The catalytic inner cylinder is provided with a receiving cavity for receiving the material to be catalyzed and is provided with a plurality of feeding pipes;

[0008] The first lamp is coaxially arranged with the catalytic inner cylinder;

[0009] The catalytic oxidation plate is arranged in the catalytic inner cylinder in parallel with the radial direction of the catalytic inner cylinder. There are two catalytic oxidation plates, and the two catalytic oxidation plates are arranged at intervals along the axial direction of the catalytic inner cylinder, dividing the accommodating cavity of the catalytic inner cylinder from top to bottom into an upper accommodating cavity, a middle accommodating cavity and a lower accommodating cavity along the axial direction of the catalytic inner cylinder;

[0010] The first light ring plate is arranged between the two catalytic oxidation plates, is coaxially arranged with the catalytic inner cylinder, and is provided with a plurality of through holes;

[0011] The catalytic outer cylinder is provided with an outer accommodating cavity, and the outer accommodating cavity is communicated with the middle accommodating cavity. The catalytic outer cylinder is provided with a discharge pipe, and a valve is provided on the discharge pipe.

[0012] In some embodiments, a plurality of second lamp tubes connected to the two catalytic oxidation plates are evenly disposed between the two catalytic oxidation plates, and the second lamp tubes are located on a side of the first lamp ring plate close to the axis of the catalytic inner cylinder.

[0013] In some embodiments, the second lamp tube extends along the axial direction of the catalytic inner cylinder.

[0014] In some embodiments, the second lamp tube includes a second tube body and a purple light bead disposed in the second tube body, the two catalytic oxidation plates and the catalytic inner cylinder are slidably connected, and the second tube body is a hose.

[0015] In some embodiments, the catalytic oxidation plate is a porous foam ceramic plate.

[0016] In some embodiments, the first lamp tube extends along the axial direction of the catalytic inner cylinder.

[0017] In some embodiments, the catalytic oxidation plate includes a body and a catalytic oxidant coated thereon.

[0018] The technical solution of the utility model has at least the following advantages and beneficial effects:

[0019] (1) The utility model provides two catalytic oxidation plates arranged at intervals along the axial direction of the catalytic inner cylinder in the catalytic inner cylinder. Both catalytic oxidation plates are porous foam ceramic plates. When gas or liquid passes through the catalytic oxidation plates, solid impurities can be blocked by their porous structure. The porous foam ceramic plates are coated with catalytic oxidant. Gas or liquid adhered to the catalytic oxidant enters the middle accommodation cavity separated by the two catalytic oxidation plates through the catalytic oxidation plates. Since the middle accommodation cavity is provided with a first lamp ring plate and a second lamp tube, the first lamp tube cooperates to catalytically oxidize the material located in the middle accommodation cavity. The combination of multiple second lamp tubes forms a fence structure. The material after catalytic oxidation passes through the gap of the "fence" and reaches the catalytic outer cylinder through the first lamp ring plate to complete the catalytic effect.

[0020] (2) The catalytic inner cylinder of the present invention is provided with feed pipes at both ends. When the catalytic inner cylinder is fed from both ends, the materials at both ends collide in the middle, which increases the mobility of the materials inside the device and ensures that the materials fully contact the light source and fully react, thereby further increasing the uniformity of the catalytic oxidation of the materials.

[0021] (3) The utility model is provided with a second lamp tube, including a second tube body and a purple light bead arranged in the second tube body, the two catalytic oxidation plates and the catalytic inner cylinder are slidably connected, and the second tube body is a hose. When the catalytic inner cylinder is fed with materials through the feeding pipes at both ends, the two catalytic oxidation plates are pushed to move relative to each other, driving the hose to shake, thereby helping the materials inside it to collide. The internal agitation can be adjusted to a certain extent by adjusting the feeding rate.

[0022] (4) The utility model has reasonable design, simple structure and good practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] In this embodiment, the catalytic oxidation plate 300 is a porous foam ceramic plate.

[0046] In this embodiment, the first lamp tube 200 extends along the axial direction of the catalytic inner tube 100 .
