[0027] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0028] The applicant noted that the existing flat-plate reactor assembly scheme generally achieves the sealing of the reactor through screw fastening. The screw fastening method requires the processing of screw holes on the bottom plate of the reactor cover, and the force points will be concentrated on the screw points, resulting in uneven force around the flat-plate reactor, a high sealing failure rate, poor sealing, and low reactor disassembly and assembly efficiency.

[0029] In view of this, combined with Figure 1-Figure 7 , this embodiment provides a flat-plate reactor, aiming to overcome at least one of the above-mentioned technical problems.

[0030] In the following embodiments, a first direction x, a second direction y and a third direction z intersecting each other are introduced, wherein the first direction x is parallel to the width direction of the flat-plate reactor, the second direction y is parallel to the length direction of the flat-plate reactor, and the third direction z is parallel to the height direction of the flat-plate reactor.

[0031] This embodiment provides a flat-plate reactor, such as Figure 1-Figure 7As shown, it includes: a top plate 1, a bottom plate 2, a first sealing ring 5, a card edge strip 3, a pad 4 and a reaction component 7. The top plate 1 is arranged in parallel with the bottom plate 2. The top plate 1 is a transparent plate, which can be an acrylic plate, so that light can pass through the top plate 1 to illuminate the reaction component for photocatalytic reaction. The first sealing ring 5 is arranged between the top plate 1 and the bottom plate 2 along the periphery thereof. A sealed cavity 9 is formed between the top plate 1, the bottom plate 2 and the first sealing ring 5, and the sealed cavity 9 is arranged inside the area surrounded by the first sealing ring 5. The reaction component 7 is arranged in the sealed cavity 9, and the reaction component 7 provides a carrier for photocatalysis and is the main area for photocatalytic reaction.

[0032] The backing plate 4 is arranged along the periphery of the top plate 1 and the bottom plate 2 and is respectively pressed on the upper side of the top plate 1 and the lower side of the bottom plate 2. The backing plate 4 can be a plastic backing plate with adjustable thickness, which is used to protect the top plate 1 and the bottom plate 2 during the assembly process and can also be used to adjust the compression rate of the first sealing ring 5.

[0033] The card edge strip 3 has a card groove 31 along its length direction and the card edge strip 3 is arranged around the top plate 1 and the bottom plate 2, and the top plate 1, the bottom plate 2, the pad 4 arranged on the upper side of the top plate 1 and the pad 4 arranged on the lower side of the bottom plate 2 are all stuck in the card groove 31. The card groove 31 of the card edge strip 3 is U-shaped, the upper side of the card edge strip 3 is pressed on the pad 4 on the upper side, and the lower side of the card edge strip 3 is pressed under the pad 4 on the lower side. The card edge strip 3 has good rigidity, so that the distance between its upper side and lower side can be kept constant, so that it has a good compression effect on the periphery of the top plate 1 and the bottom plate 2, so that the reactor maintains good sealing. The distance between the upper side and the lower side of the card edge strip 3 is the distance to achieve a certain compression rate of the first sealing ring after the reactor is assembled. The card edge strip 3 can be made of a metal plate.

[0034] Specifically, the top plate 1 and the bottom plate 2 are both rectangular, 4 card edge strips 3 are provided, and 8 pads 4 are provided. The 4 card edge strips are respectively provided on the four sides of the top plate 1 and the bottom plate 2, and 2 pads are provided on each side to facilitate the installation of the card edge strips 3. Two adjacent card edge strips 3 are connected at the corners of the top plate 1 and the bottom plate 2 to achieve uniform sealing.

[0035] In addition, the edge strips 3 on two adjacent sides of the top plate 1 and the bottom plate 2 can be connected. The number of the edge strips 3 and the backing plate 4 can be adjusted according to the shapes of the top plate 1 and the bottom plate 2, so that the edge strips 3 are easy to install.

[0036] When assembling the flat-plate reactor of the present embodiment, the peripheries of the top plate 1 and the bottom plate 2 can be firstly squeezed relative to each other, and a pad 4 of suitable thickness can be selected and pressed on the upper side of the top plate 1 and the lower side of the bottom plate 2, and then the top plate 1, the bottom plate 2, the pad 4 arranged on the upper side of the top plate 1 and the pad 4 arranged on the lower side of the bottom plate 2 are all clamped in the clamping groove 31, and then the relative squeezing force on the top plate 1 and the bottom plate 2 is removed. At this time, the first sealing ring 5 is compressed by the squeezing effect of the top plate 1 and the bottom plate 2, thereby sealing the periphery of the reactor. Since the card edge strip 3 and the pad 4 are both extended along the periphery of the top plate 1 and the bottom plate 2, the card edge strip 3 and the pad 4 apply uniform pressure to the periphery of the top plate 1 and the bottom plate 2, so that the first sealing ring 5 is stressed as a whole, the compression rate of the sealing ring is consistent, and the sealing failure is reduced; and the reactor is simpler to process, with fewer components and low cost, and can be used without screws, with high disassembly and assembly efficiency, low failure rate, simpler maintenance, and a simple and elegant appearance.

[0037] As a preferred embodiment, the height of the card slot 31 is less than the sum of the thicknesses of the top plate 1, the bottom plate 2, the first sealing ring 5, and the upper and lower pads 4, so that the top plate 1, the bottom plate 2, the first sealing ring 5, and the upper and lower pads 4 are compressed and tightened when they are stuck in the card slot 31, thereby improving the sealing performance of the sealed cavity. The thickness of the first sealing ring 5 is greater than the thickness of the reaction assembly 7. The height of the card slot 31 is the distance between the upper and lower sides of the card edge strip 3.

[0038] The height of the slot 31 is greater than or equal to the sum of the thicknesses of the top plate 1, the bottom plate 2, the reaction assembly 7, and the upper and lower pads 4, so that the top plate 1, the bottom plate 2, the reaction assembly 7, and the upper and lower pads 4 can enter the slot 31 when the first sealing ring 5 is compressed.

The first external connector 8 and the second external connector 10 can serve as an inlet and an outlet for fluid to enter the sealed cavity 9 of the reactor, respectively.

[0040] When the reactor of this embodiment is in use, the fluid enters the sealed cavity 9 from the first external connector 8, undergoes a photocatalytic reaction through the reaction assembly 7, and then flows out of the reactor from the second external connector 10 at the other end.

[0041] Preferably, when installing the card edge strip 3, the top plate 1 and the bottom plate 2 are relatively squeezed by evacuating the inside of the sealed cavity. Specifically, one of the first external joint 8 and the second external joint 10 is blocked and the other is connected to a vacuum pump, and the inside of the sealed cavity is evacuated by the vacuum pump, and the top plate 1 and the bottom plate 2 are relatively squeezed under the action of external air pressure, and then the pad 4 and the card edge strip 3 are installed, which is simple and convenient to operate and improves installation efficiency.

[0042] As a preferred embodiment, the flat-plate reactor provided in this embodiment further includes a limiting side plate 6, such as Figure 1 and Figure 6 As shown, the limiting side plate 6 is arranged along the periphery of the top plate 1 and the bottom plate 2, and is located between the top plate 1 and the bottom plate 2 at the upper limit in the third direction z. The limiting side plate 6 is arranged on the outer side of the reaction component 7 and forms a first sealing groove 61 adapted to the first sealing ring 5 between the limiting side plate 6 and the outer side edge of the reaction component 7, and the first sealing ring 5 is arranged in the first sealing groove 61. The first sealing groove 61 plays a positioning role for the first sealing ring 5. The outer side edge of the limiting side plate 6 is aligned with the outer side edge of the top plate 1 and the bottom plate 2 in the third direction z. The thickness of the limiting side plate 6 is equal to the thickness of the reaction component 7 and is less than the thickness of the first sealing ring 5 in the natural state. The above-mentioned description of the outside or inside is relative to the center position of the reactor, the position close to the center is the inside, and the position away from the center is the outside. The first sealing ring 5 has a certain elasticity and can be made of elastic materials such as rubber or silicone.

[0043] As a preferred embodiment, the reaction assembly 7 includes a guide loading plate 71 and a plurality of load plates 72.

The spaces 714 play a role of positioning the load plates 72, and the plurality of load plates 72 are arranged in an array along the second direction y and arranged on the same horizontal plane. The isolation bar 715 and the guide loading plate 71 are an integrated structure.

The inlet area 711 and the outlet area 717 are respectively provided at the two ends of the guide loading plate 71 in the second direction y.

[0045] When the reactor of this embodiment is in use, the fluid enters the inlet area 711 through the first external connector 8, then flows to the multiple support plates 72 through the flow channel 713, flows to the outlet area 717 after undergoing photocatalytic reaction on the support plates 72, and then flows out of the sealed cavity through the second external connector 10.

The fluid enters the drainage groove 86 through the outlet area 717 and then flows out of the second external joint 10.

[0048] This embodiment also provides a method for assembling a flat-plate reactor, comprising the following steps:

[0049] Step A, evacuate the sealing cavity 9 to make the sealing cavity 9 in a negative pressure state, and the top plate 1 and the bottom plate 2 squeeze the first sealing ring 5 to be in an over-pretightened state; the over-pretightened state means that the sum of the thicknesses of the top plate 1, the bottom plate 2, the squeezed first sealing ring 5 and the pads 4 on the upper and lower sides is less than the height of the card slot 31.

[0050] Step B: In the over-preloaded state, the top plate 1 , the bottom plate 2 , the pad 4 disposed on the upper side of the top plate 1 , and the pad 4 disposed on the lower side of the bottom plate 2 are all clamped in the clamping groove 31 of the clamping edge strip 3 .

[0051] Step C, release the vacuum in the sealing chamber 9, and the first sealing ring 5 rebounds to the pre-tightened state, so as to achieve the sealing of the reactor sealing chamber. The pre-tightened state is that the sum of the thickness of the top plate 1, the bottom plate 2, the compressed first sealing ring 5 and the pads 4 on the upper and lower sides is equal to the height of the card slot 31. The thickness of the first sealing ring 5 in the over-pre-tightened state is less than the thickness of the first sealing ring 5 in the pre-tightened state.

[0052] As a preferred embodiment, in step A, one of the first external connector 8 and the second external connector 10 communicating with the sealing chamber 9 is blocked and the other one is connected to the vacuum pump.

[0053] The flat-plate reactor of this embodiment realizes the installation of the edge strip 3 and the pad 4 by means of negative pressure assembly, so that the sealed cavity 9 of the reactor is sealed. The negative pressure assembly method is simpler to operate and has higher reactor assembly efficiency; since the first sealing ring has good compressibility, the reactor is over-preloaded and compressed, and has a wider range of solvent applicability to suit more application scenarios; since the top plate 1 and the bottom plate 2 have good rigidity, the reactor is evenly stressed under high vacuum.

[0054] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make several modifications and improvements without departing from the creative concept of the present invention, which should be included in the protection scope of the present invention.
