Description

Technical Field

[0001] The present invention relates to the technical field of solar panel recycling, and particularly to a classified recycling and disassembly system for solar panels based on a pyrolysis process. Background Art

[0002] The closed-loop recycling application of solar cell modules is based on recycling raw materials from waste solar panels, recycling raw materials such as glass, silver, silicon, and copper in the solar panels, and preparing new solar panels. The pyrolysis technology involved therein is a technology that heats waste solar panels to a high temperature state and decomposes them through chemical reactions;

[0003] During the pyrolysis process, waste photovoltaic panels are pre-dismantled. After removing the external aluminum frame and glass, the remaining waste is crushed and pressed into a cylindrical structure and sent into a pyrolysis furnace. After heating to a high temperature, the organic substances in the module decompose into gases and liquids, and the inorganic substances are converted into solids. Through subsequent separation and purification processes, high-purity organic and inorganic substances can be obtained;

[0004] However, during the pyrolysis process, a large amount of flue gas is generated, including acidic waste gas, organic waste gas, and diffusion waste gas. However, there are deficiencies in the treatment of pyrolysis flue gas in the prior art. Most of them use a purification end with a fixed absorption capacity to complete the flue gas absorption method, which cannot perform feedback adjustment of the purification end according to the flue gas concentration and flue gas volume. The lack of intelligent supervision means results in the purification end always operating at full load for absorption, and the flue gas absorption efficiency is low;

[0005] Moreover, the solar panel waste placed in the pyrolysis furnace is always in a relatively fixed state with the furnace body, which is not conducive to generating effective and uniform heat supply, and the pyrolysis efficiency is low. For this reason, this application proposes a solution. Summary of the Invention

[0014] It is further set that: the intermittent feeding component includes a sealed box penetrated through the feeding pipe. The sealed box is provided with a feeding port corresponding to the pipe hole of the feeding pipe. An outer convex plate and an inner concave plate are horizontally installed and butted inside the sealed box.

[0043] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0044] Embodiment 1: In view of the problems that the purification end cannot be feedback-regulated according to the flue gas concentration and flue gas volume, the lack of intelligent supervision means leads to the purification end always operating at full load for suction, and the pyrolysis process of solar panel waste cannot be evenly heated, the following technical solutions are proposed:

[0045] Refer to Figure 1 - Figure 10 As shown, in this embodiment, the solar panel classification recycling and disassembling system based on the pyrolysis process includes an outer tank body and an inner tank body 11 arranged inside the outer tank body. The outer tank body includes a lower outer tank 1 and an upper outer tank 2 stacked on each other. A control panel is embedded on the lower outer tank 1;

[0046] A driving assembly 8 for deflecting the inner tank body 11 to both sides is arranged in the middle of the lower side of the lower outer tank 1. The driving assembly 8 includes a connecting rod 82 arranged outside the inner tank body 11 and horizontally penetrating to the outside of the lower outer tank 1 at the end. A motor 81 is installed at the outer end of one of the connecting rods 82. A steam distribution pipe 14 penetrating into the inner tank body 11 is commonly installed between the two connecting rods 82. The end of the steam distribution pipe 14 far from the motor 81 is connected to a second steam inlet pipe 10. A first steam inlet pipe 6 is installed through the middle of the lower outer tank 1 vertically corresponding to the steam distribution pipe 14;

[0047] The pyrolysis structure of the present invention is a structural design combining an inner tank and an outer tank. Specifically, waste solar panels are located in the inner tank 11, and high-temperature steam is input synchronously to the inner and outer sides of the inner tank 11. The cavity between the outside of the inner tank 11 and the inner tank is heated in a "steam threshold" manner, and the high-temperature steam introduced into the inner tank 11 is combined to achieve synchronous heating inside and outside to achieve the purpose of pyrolysis;

[0048] A purification component 4 is provided at the upper end of the upper outer tank 2. The purification component 4 includes a suction pipe 43 and a suction pipe 44 that communicate with the inside of the outer tank. The suction pipe 43 and the suction pipe 44 are jointly connected to a collecting pipe 41 connected to a purification device;

[0049] Refer to Figure 4 As shown, the upper end of the inner tank 11 is open and provided with a feed pipe orifice 12, and the lower end of the inner tank 11 is provided with a discharge plate 17 for controlling the discharge of the pyrolyzed waste solar panel column. An intermittent feeding component 7 for feeding waste solar panels is installed on the upper outer tank 2 corresponding to the feed pipe orifice 12.

[0050] Refer to Figure 6 As shown, a diversion disk 13 is installed at the inner end of the steam inlet pipe 6 close to the surface of the inner tank 11. The inner side of the diversion disk 13 is a concave structure and matches the outer surface of the inner tank 11. Diversion holes 18 communicating with the inside of the steam inlet pipe 6 are opened on the outer side of the diversion disk 13. The steam outlet direction of the diversion holes 18 is tangent to the outer surface of the inner tank 11. Upper spray nozzles 15 and lower spray nozzles 16 facing outward are symmetrically installed at the upper and lower ends of the outer ring surface of the steam distribution pipe 14. When the inner tank 11 rotates, the high-temperature steam sprayed by the upper spray nozzles 15, the lower spray nozzles 16 and the diversion holes 18 respectively provides internal and external heating for the waste solar panels inside the inner tank 11;

[0051] The drive component further includes a rotating frame 85 provided at the output end of the motor 81. The other end of the rotating frame 85 is connected to a driving turntable 83 and a contact block 84. A driven rotating rod 86 sleeved with the driving turntable 83 is installed at the outer end of the connecting rod 82 close to the motor 81. A rotating groove 87 matching the contact block 84 is opened at the outer end of the driven rotating rod 86. The contact block 84 is installed on the inner ring side of the driving turntable 83, and the contact block 84 is located in the middle of the rotating groove 87 in the initial state;

[0052] A control system is provided inside the control panel. The control system includes a parameter acquisition unit, a flue gas purification management unit, an exhaust management unit, a linkage control unit and a processor that are communicatively connected;

[0053] The parameter acquisition unit is used to obtain the gas concentration value QN of the pyrolysis flue gas during the pyrolysis of solar panel waste. The gas concentration value QN includes the flue gas concentration information and the flue gas emission information of the pyrolysis flue gas discharged from the inner tank 11 to the purification device, and is sent to the flue gas purification management unit for evaluation and analysis of the gas concentration value QN by the processor. The evaluation and analysis process of the flue gas purification management unit is as follows:

[0054] Step 1: Obtain the flue gas concentration information YN of the pyrolysis flue gas between the outer tank and the inner tank 11, and the total flue gas emission YQ through the suction pipe 1 43 and the suction pipe 2 44. The flue gas concentration information YN is measured by a photoelectric smoke sensor arranged outside the inner tank 11, and the flue gas emission YQ is obtained by measuring the flue gas emission rate by the flow sensors arranged on the suction pipe 1 43 and the suction pipe 2 44, and then calculating the flue gas emission YQ in the current time period in combination with the emission time;

[0055] Step 2: Construct the calculation formula of the gas concentration value QN , where a, b, and c are preset proportional coefficients and a > b > c > 0, and k is a preset fault tolerance factor coefficient and k > 0;

[0056] Step 3: The flue gas purification management unit sends the gas concentration value QN of the pyrolysis flue gas to the exhaust management unit.

[0057] The exhaust management unit compares and analyzes the received gas concentration value QN with the preset gas concentration threshold, and sends the comparison and analysis result to the linkage control unit. The linkage control unit performs relevant start-up actions. The process is as follows:

[0058] When the gas concentration value QN is greater than the gas concentration threshold, no signal is generated at this time;

[0059] When the gas concentration value QN is within the gas concentration threshold, the linkage control unit generates a deflection control signal and sends it to the motor 82 at this time. The motor 82 starts to drive the active turntable 83 to reciprocate forward and reverse. At this time, the driven rod 86 moves repeatedly in the chute 87 by the contact block 84 on the active turntable 83, and drives the driven rod 86 to deflect left and right during the movement process, that is, the inner tank 11 inside the outer tank can realize reciprocating left and right deflection, and no deflection action is generated when the contact block 84 and the two sides of the chute 87 are not in contact during the deflection process, forming a shaking of the solar cell waste column inside the inner tank 11, effectively realizing the uniform heating of the solar panel waste column and improving the pyrolysis efficiency;

[0060] When the gas concentration value QN is less than the gas concentration threshold, the linkage control unit generates a deflection control signal and also generates an intermittent feeding signal at this time. When generating the deflection control signal, refer to the above content. When generating the intermittent feeding signal, it is sent to the electric push rod 72. The electric push rod 72 starts cyclically and controls the waste column of solar panels in the feeding pipe 3 to achieve intermittent feeding. The waste column of solar panels drops into the inner tank 11, thereby increasing the subsequent flue gas generation volume.

[0061] Basic principle: On the one hand, through the structural design of combining the inner and outer tanks, the waste solar panels in the inner tank 11 are heated by the "steam threshold" presented by the cavity between the outside of the inner tank 11 and the inner tank, combined with the method of directly introducing high-temperature steam into the inner tank 11, to jointly achieve the purpose of synchronous heating inside and outside.

[0062] On the other hand, during the synchronous heating inside and outside, intelligent control is coupled with the flue gas concentration and the total flue gas emission volume, and the feeding and deflection control in the pyrolysis process are adjusted by feedback with the flue gas purification volume, so as to realize the feedback adjustment of the purification end according to the flue gas concentration and the flue gas volume, ensuring that the purification end always operates at normal load to absorb flue gas and the waste solar panels are evenly pyrolyzed.

[0063] Embodiment 2: This embodiment optimizes the structure in Embodiment 1:

[0064] Refer to Figure 3 and Figure 8 As shown, the collecting pipe 41 is of a circular ring structure and is internally connected to the first suction pipe 43 and the second suction pipe 44. The upper end of the collecting pipe 41 is provided with a purification discharge pipe 42 connected to the suction end of the purification device. When the inner tank 11 deflects, it swings to both sides, and the feeding pipe orifices 12 of the inner tank 11 at the swing endpoints correspond to the first suction pipe 43 and the second suction pipe 44 respectively;

[0065] In addition, there is also provided: Refer to Figure 3 and Figure 10 As shown, the intermittent feeding assembly 7 includes a sealed box 71 penetrating through the feeding pipe 3. The sealed box 71 is provided with a feeding port 76 corresponding to the pipe orifice of the feeding pipe 3. Horizontally installed in the sealed box 71 are a convex outer plate 74 and a concave inner plate 75 that are butt-jointed. Electric push rods 72 are installed at both lower ends of the sealed box 71. The output end of the electric push rod 72 is connected to a fixed rod 73. The fixed rod 73 is in a "U" shape and is respectively connected to the convex outer plate 74 and the concave inner plate 75;

[0066] During feeding: The waste columns of solar panels in the feeding pipe 3 enter one by one. That is, after the waste columns on the convex outer plate 74 and the concave inner plate 75 are discharged, the next waste column can continue to enter. When the electric push rod 72 is started, the convex outer plate 74 and the concave inner plate 75 are driven by the fixed rod 73 to separate from each other. At this time, the waste column in the feeding pipe 3 falls into the inner tank body 11 through the feeding pipe orifice 12, and collides with the steam distribution pipe 14 and scatters in the inner tank body 11 to form an irregular stack, which is conducive to achieving uniform and effective pyrolysis under the condition of synchronous heating inside and outside, and avoiding the situation of insufficient internal heating caused by too tight stacking.

[0067] When not feeding: At this time, the electric push rod 72 drives the convex outer plate 74 and the concave inner plate 75 to merge. At this time, the next waste column to be pyrolyzed falls into the feeding pipe 3 and waits for feeding.

[0068] It should be noted again that: An outer expansion tank 9 is installed on the outside of the lower outer tank 1 and the upper outer tank 2 together. A return pipe 5 is sleeved outside the corresponding steam inlet pipe 6 of the outer expansion tank 9. The return pipe 5 is in a "U" - shaped structure. The return pipe 5 is connected to the inside of the outer tank body and a condenser is arranged in the middle. The setting of the condenser and the return pipe 5 is used to collect the water vapor generated between the outer tank body and the inner tank body 11 and return it to the outer tank body, which is convenient for controlling the temperature of the entire pyrolysis furnace.

[0069] In summary: The present invention is through the structural design of combining the inner and outer tank bodies, so that the waste of solar panels in the inner tank body is heated by the "steam threshold" presented by the cavity between the outside of the inner tank body and the inner tank body, combined with the method of directly introducing high - temperature steam into the inner tank body, to jointly achieve the purpose of synchronous heating inside and outside; during the synchronous heating inside and outside, the intelligent control is combined with the flue gas concentration and the total flue gas emission amount, and the feeding and deflection control in the pyrolysis process are adjusted by the feedback of the flue gas purification amount, so as to realize the feedback adjustment of the purification end according to the flue gas concentration and the flue gas volume, ensuring that the purification end always operates at normal load to absorb the flue gas and the waste of solar panels is evenly pyrolyzed.

[0070] In the process of flue gas purification analysis and management, the current situation of flue gas generation is determined through the flue gas concentration information and the flue gas emission amount information. The exhaust management unit analyzes the comparison of the gas concentration values in real - time, and then the linkage control unit makes flue gas emission control, so that the flue gas purification amount feeds back and adjusts the feeding and deflection control in the pyrolysis process, and makes relevant start - up control according to the numerical relationship between the gas concentration value and the gas concentration threshold value, ultimately ensuring that the purification end always operates at normal load.
