Description

Technical Field

[0001] The present disclosure relates to the field of photovoltaic manufacturing technology, and in particular to a photovoltaic waste gas slag treatment system. Background Art

[0002] Photovoltaic combustion currently mainly heats the kiln by reacting and burning gases. First, the photovoltaic waste gas is introduced into the reaction chamber of a natural gas flame such as a plasma flame for heating. Then, a combustion-supporting gas is injected into the reaction chamber to help the flame burn more violently and react with the photovoltaic waste gas. The burned photovoltaic waste gas and waste residue are then insulated and utilized through a vertically installed lattice body. Finally, the photovoltaic waste gas is discharged through a brick flue.

[0003] During the exhaust process, the waste residue contained in the photovoltaic waste gas will be directly retained inside the brick flue, which is extremely difficult to clean. On the one hand, the brick flue is hot and it is difficult for people to enter to clean it; on the other hand, the waste residue in the photovoltaic waste gas is dispersed and difficult to handle at once.

[0028] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0029] like Figure 1 As shown, the present disclosure provides a photovoltaic waste gas slag treatment system, including a flue 1, a mesh drum assembly 2, a fixed air isolation device 3, a driving device (not shown) and a slag collection device 5.

[0030] The flue 1 comprises a flue casing 10 , and a flue air inlet 11 and a flue air outlet 12 are respectively arranged on two opposite sides of the flue casing 10 .

[0031] The mesh drum assembly 2 is provided with a slag outlet 20, the mesh drum assembly 2 is accommodated inside the flue shell 10, the fixed air-isolating device 3 is provided with a through hole 31, the end of the mesh drum assembly 2 close to the flue air inlet 11 is sealed and fixedly connected to the through hole 31, and the fixed air-isolating device 3 is sealed and connected to the inner wall of the flue shell 10.

[0032] The driving device is drivingly connected to the mesh drum assembly 2 so that the mesh drum assembly 2 can rotate. The slag collecting device 5 includes a slag collecting port 50 located inside the flue housing 10 , and the slag collecting port 50 is located below the slag outlet 20 .

[0033] In a preferred embodiment, if Figure 1 As shown, the mesh drum assembly 2 includes a bearing 21 and a mesh drum 22. The bearing 21 includes a bearing inner ring 23 and a bearing outer ring 24, and one end of the mesh drum 22 close to the flue air inlet 11 is connected to the bearing inner ring 23. It should be understood by those skilled in the art that the end of the mesh drum 22 close to the flue air inlet 11 can be connected to the bearing inner ring 23 by a connection method known in the prior art (for example, by fasteners or rotating shafts and other components) to ensure that the mesh drum 22 can be driven to rotate when the driving device drives the bearing inner ring 23 to rotate.

[0034] In a preferred embodiment, if Figure 3As shown, the fixed air-baffle device 3 is a fixed air-baffle plate 3, a through hole 31 is provided at the center of the fixed air-baffle plate 3, and the outer ring 24 of the bearing is sealed and fixedly connected to the through hole 31 of the fixed air-baffle plate 3. The place where the fixed air-baffle plate 3 is sealed and connected to the inner wall of the flue shell 10 has a shape that matches the inner wall of the flue shell 10, so as to form a good sealed connection. On the one hand, the fixed air-baffle plate 3 provided in the present invention can play a role in fixing and supporting the mesh drum assembly 2. On the other hand, after the photovoltaic waste gas enters the interior of the flue shell 10 through the flue air inlet 11, the photovoltaic waste gas can be intercepted to ensure that the photovoltaic waste gas can all flow into the mesh drum 22, so as to collect the waste residue in the photovoltaic waste gas.

[0035] In a preferred embodiment, a vertical filter screen 6 is disposed inside the flue housing 10, the top end of the vertical filter screen 6 is connected to the top inner wall 13 of the flue housing 10, and the bottom end of the vertical filter screen 6 is connected to the bottom inner wall 14 of the flue housing 10. In addition, the mesh drum 22 may have a structure with one end open, such as Figure 1 and Figure 2 As shown, one end of the mesh drum 22 close to the flue outlet 12 has an open opening 25. In a preferred embodiment, the vertical filter screen 6 can cover the entire opening 25 and there is a slight gap between the vertical filter screen 6 and the opening 25 to ensure that the vertical filter screen 6 does not interfere with the rotational movement of the mesh drum 22, and can also prevent the waste residue in the photovoltaic exhaust gas from being thrown out of the mesh drum 22 through the opening 25 during the rotation of the mesh drum 22. In addition, the vertical filter screen 6 can also perform the final step of filtering the photovoltaic exhaust gas. It should be understood by those skilled in the art that the size of the mesh of the vertical filter screen 6 disclosed in the present invention only allows the photovoltaic exhaust gas to pass through, and the waste residue in the photovoltaic exhaust gas is intercepted by the vertical filter screen 6.

[0036] like Figure 1 and Figure 3 As shown, the mesh drum 22 includes a drum side wall 29 and a drum end connected to the bearing inner ring 23, a side wall filter 26 is arranged on the inner wall of the drum side wall 29, and an end filter 27 is arranged at the drum end, and the slag outlet 20 is arranged at the adjacent opening 25 of the side wall filter 26. The size of the mesh of the end filter 27 allows the photovoltaic waste gas and the waste residue in the photovoltaic waste gas to pass through, however, the side wall filter 26 only allows the photovoltaic waste gas to pass through, so that the photovoltaic waste gas and the waste residue can all enter the mesh drum 22 through the end filter 27. Then, the photovoltaic waste gas generates a vortex as the mesh drum 22 rotates, and the rotating photovoltaic waste gas collides with the side wall filter 26 and, under the action of centrifugal force, the waste residue in the photovoltaic waste gas is forced to leave the photovoltaic waste gas, and the waste residue can finally enter the slag outlet 20 and be collected in a centralized manner.

[0037] A screen 28 is also provided on the inner wall of the side wall filter 26. The screen 28 is arranged to gradually thicken from the opening 25 of the mesh drum 22 toward the end filter 27 of the mesh drum 22, so that the screen 28 has a slope. The screen 28 also only allows photovoltaic waste gas to pass through. The screen 28 is designed to have a sloped structure, so that the waste residue intercepted in the mesh drum 22 can be accelerated to roll into the residue outlet 20 along the slope direction.

[0038] A plurality of air hammers 7 are arranged on the drum side wall 29 of the mesh drum 22, and the air hammers 7 are operably connected to an air source (not shown). After the air source is connected, the air hammers 7 can perform a cyclic reciprocating motion, thereby reciprocatingly knocking and vibrating the outer wall of the drum side wall 29 of the mesh drum 22, so as to knock off the waste residues staying on the side wall filter screen 26 and / or the screen screen 28, thereby promoting the waste residues to finally roll into the slag outlet 20 along the slope direction. It should be understood by those skilled in the art that the air hammers 7 can be arranged on the outer wall of the drum side wall 29 of the mesh drum 22 by known connection methods such as fasteners, and the cyclic reciprocating motion of the air hammers 7 can be achieved by methods known in the prior art, which will not be described in detail here.

[0039] A plurality of spray devices 8 are provided on the top of the flue housing 10, and the spray devices 8 are operably connected to a fluid source (not shown). After the fluid source (e.g., cooling water) is connected, the spray devices 8 can spray cooling water onto the outer wall of the drum side wall 29 of the mesh drum 22 to cool down the photovoltaic exhaust gas inside the mesh drum 22, thereby preventing the crystallization of boron oxide in the photovoltaic exhaust gas. It should be understood by those skilled in the art that the spray device 8 can be installed on the top of the flue housing 10 by a known connection method such as a fastener, or a spray device known in the prior art can be used, which will not be described in detail here.

[0040] The driving device is arranged outside the flue housing 10, and the output shaft (not shown) of the driving device passes through the flue housing 10 and is drivingly connected to the bearing inner ring 23. It should be understood by those skilled in the art that the driving device can be a motor, and the motor can be used to drive the bearing inner ring 23 to rotate in a manner known in the prior art, thereby further driving the mesh drum 22 connected to the bearing inner ring 23 to rotate, which will not be described in detail here.

[0041] The slag collecting device 5 is a slag collecting trough 5 , a part of which passes through the flue shell 10 so that a slag collecting port 50 is arranged in the flue shell 10 . The length of the slag collecting port 50 is greater than the diameter of the mesh drum 22 . A waste slag cleaning port 51 is arranged at the bottom of the slag collecting trough 5 .

[0042] In a preferred embodiment, the slag collecting tank 5 can be, for example, a box-type structure with an open opening (slag collecting port 50), a portion of the slag collecting tank 5 is arranged in the flue housing 10 and the slag collecting port 50 is located below the slag outlet 20, and the remaining portion is located below the bottom of the flue housing 10. The length of the slag collecting port 50 is set to be greater than the diameter of the mesh drum 22 so as to cover the rotation path of the slag outlet 20, thereby ensuring that the waste slag can still smoothly fall from the slag outlet 20 into the range of the slag collecting port 50 when the mesh drum 22 rotates, and finally collected in the slag collecting tank 5, thereby achieving the purpose of removing the waste slag while collecting the waste slag while rotating the mesh drum 22 during the process of introducing photovoltaic waste gas. The operator can periodically open the waste slag cleaning port 51 to clean up the waste slag accumulated in the slag collecting tank 5.
