Description

Technical Field

[0001] The invention relates to the technical field of solar panel recycling, and in particular to a solar panel classification, recycling and disassembly system based on a pyrolysis process. Background Art

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

[0003] During the pyrolysis process, the waste photovoltaic panels are disassembled in advance, and after the external aluminum frame and glass are removed, the remaining waste is crushed and pressed into a cylindrical structure and sent to the pyrolysis furnace. After heating to a high temperature, the organic matter in the component is decomposed into gas and liquid, and the inorganic matter is converted into solid. After the subsequent separation and purification process, 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 diffused waste gas. However, there are deficiencies in the existing technology for treating pyrolysis flue gas. Most of them use a purification end with a fixed absorption amount to complete the flue gas absorption. It is impossible to perform feedback adjustment of the purification end according to the flue gas concentration and flue gas volume.

[0043] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Embodiment 1: In view of the problem that the purification end cannot be feedback-regulated according to the flue gas concentration and the flue gas volume, the lack of intelligent supervision means causes the purification end to always operate at full load, and the pyrolysis process of solar panel waste cannot obtain uniform heating, the following technical solution is proposed:

[0045] Reference Figure 1 - Fig.10 As shown, the solar panel classification, recycling and disassembly system based on the pyrolysis process in this embodiment 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 in a stacked manner, and a control panel is embedded in 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 on the outer side of the inner tank body 11 and the end of which is horizontally penetrated to the outside of the lower outer tank 1. 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 installed between the two connecting rods 82. The end of the steam distribution pipe 14 away from the motor 81 is connected to a steam inlet pipe 2 10. A steam inlet pipe 1 6 is installed vertically through the middle of the lower outer tank 1 corresponding to the steam distribution pipe 14.

[0047] The pyrolysis structure of the present invention is a structural design combining inner and outer tanks. Specifically, the solar panel waste is located in the inner tank 11, and high-temperature steam is simultaneously input to the inner and outer sides of the inner tank 11, so that the cavity between the outer and inner tanks of the inner tank 11 is heated in a "steam threshold" manner, and the purpose of pyrolysis is achieved by combining the high-temperature steam introduced into the inner tank 11 to achieve synchronous heating of the inner and outer sides.

[0048] A purification assembly 4 is provided at the upper end of the upper outer tank 2. The purification assembly 4 includes a suction pipe 1 43 and a suction pipe 2 44 connected to the interior of the outer tank body. The suction pipe 1 43 and the suction pipe 2 44 are commonly connected to a collection pipe 41 connected to the purification device.

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

[0050] Reference Figure 6 As shown, the inner end of the steam inlet pipe 16 is installed with a guide plate 13 close to the surface of the inner tank body 11, the inner side of the guide plate 13 is a concave structure and matches the outer surface of the inner tank body 11, and the outer side of the guide plate 13 is provided with a guide hole 18 that is connected to the inside of the steam inlet pipe 16, and the steam outlet direction of the guide hole 18 is tangent to the outer surface of the inner tank body 11. The upper and lower ends of the outer annular surface of the steam separation pipe 14 are symmetrically installed with an upper nozzle 15 and a lower nozzle 16 facing outward. When the inner tank body 11 rotates, the high-temperature steam sprayed from the upper nozzle 15, the lower nozzle 16 and the guide hole 18 respectively provide internal and external heating for the solar panel waste in the inner tank body 11;

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

[0052] The control panel has a built-in control system, which includes a parameter acquisition unit, a flue gas purification management unit, an exhaust management unit, a linkage control unit and a processor that are connected to each other in communication;

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

[0054] Step 1: Obtain the smoke concentration information YN of the pyrolysis smoke between the outer tank body and the inner tank body 11, and the total smoke emission YQ through the suction tube 1 43 and the suction tube 2 44, wherein the smoke concentration information YN is measured by the photoelectric smoke sensor arranged outside the inner tank body 11, and the smoke emission amount YQ is measured by the flow sensor arranged on the suction tube 1 43 and the suction tube 2 44 to obtain the smoke emission rate, and then the smoke emission amount YQ in the current time period is calculated in combination with the emission time;

[0055] Step 2: Construct the calculation formula of gas concentration value QN Wherein a, b and c are preset proportional coefficients and a>b>c>0, 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 results to the linkage control unit, which performs relevant startup actions. The process is as follows:

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

[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. The motor 82 starts to drive the active turntable 83 to reciprocate forward and reverse. At this time, the contact block 84 on the active turntable 83 of the driven rotating rod 86 moves repeatedly in the rotating groove 87, and drives the driven rotating rod 86 to deflect left and right during the movement, that is, the inner tank body 11 inside the outer tank body can realize reciprocating left and right deflection, and no deflection action occurs when the contact block 84 and the rotating groove 87 are not in contact during the deflection process, so that the solar cell waste column inside the inner tank body 11 is shaken, which effectively realizes uniform heating of the solar cell panel waste column and improves 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 an intermittent feeding signal at the same time. The generation of the deflection control signal refers to the above content. When the intermittent feeding signal is generated, it is sent to the electric push rod 72. The electric push rod 72 starts a cycle and controls the solar panel waste column in the feeding pipe 3 to achieve intermittent feeding. The solar panel waste column falls into the inner tank body 11, thereby increasing the subsequent flue gas generation.

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

[0062] On the other hand, in the process of synchronous internal and external heating, the flue gas concentration and the total amount of flue gas emissions are coupled with intelligent control, and the feeding and deflection control in the pyrolysis process are adjusted by combining the flue gas purification amount feedback, so as to realize feedback adjustment of the purification end according to the flue gas concentration and flue gas amount, ensuring that the purification end always operates at normal load to remove flue gas and achieve uniform pyrolysis of solar panel waste.

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

[0064] Reference Figure 3 and Figure 8 As shown, the collecting pipe 41 is a circular ring structure and is connected to the inside of the suction pipe 1 43 and the suction pipe 2 44. The upper end of the collecting pipe 41 is equipped with a purification pipe 42 connected to the suction end of the purification device. The inner tank body 11 swings to both sides when it is deflected, and the feed pipe port 12 of the inner tank body 11 at the end point of the swing corresponds to the suction pipe 1 43 and the suction pipe 2 44 respectively;

[0065] In addition, there are: Figure 3 and Fig.10 As shown, the intermittent feeding assembly 7 includes a packaging box 71 which is arranged through the feeding tube 3, and a feeding port 76 is opened in the packaging box 71 corresponding to the tube hole of the feeding tube 3. An outer convex plate 74 and an inner concave plate 75 which are opposite to each other are installed transversely in the packaging box 71. Electric push rods 72 are installed at the lower ends of both sides of the packaging box 71. The output end of the electric push rod 72 is connected to a fixing rod 73, which is in a "U" shape and is connected to the outer convex plate 74 and the inner concave plate 75 respectively.

[0066] During feeding: the solar panel waste columns in the feeding pipe 3 enter one by one, that is, the waste columns on the outer convex plate 74 and the inner concave plate 75 are discharged before continuing to enter the next waste column. When the electric push rod 72 is started, the outer convex plate 74 and the inner concave plate 75 are driven to separate from each other through the fixing rod 73. At this time, the waste columns in the feeding pipe 3 fall into the inner tank body 11 through the feeding pipe mouth 12, and collide with the steam separation pipe 14 to scatter in the inner tank body 11 to form irregular stacks, which is conducive to achieving uniform and effective pyrolysis under the condition of synchronous internal and external heat supply, and avoiding the situation of insufficient internal heat supply caused by stacking too tightly;

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

[0068] It should be noted again that an outer expansion tank 9 is installed on the outer side of the lower outer tank 1 and the upper outer tank 2. A reflux pipe 5 is sleeved on the outer side of the outer expansion tank 9 corresponding to the steam inlet pipe 6. The reflux pipe 5 is in a "U" shape. The reflux pipe 5 is connected to the inside of the outer tank body and a condenser is arranged in the middle. The condenser and the reflux pipe 5 are arranged to collect the water vapor generated between the outer tank body and the inner tank body 11, and reflux it into the outer tank body, so as to facilitate the temperature control of the entire pyrolysis furnace.

[0069] In summary, the present invention adopts a structural design combining inner and outer tanks, so that the solar panel waste in the inner tank is heated by the "steam threshold" heating method presented by the cavity between the inner tank and the inner tank, and the method of directly introducing high-temperature steam into the inner tank achieves the purpose of synchronous heating inside and outside. In the process of synchronous heating inside and outside, the intelligent control is combined with the flue gas concentration and the total amount of flue gas emissions, 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 amount, so as to ensure that the purification end always operates under normal load to remove the flue gas and the solar panel waste is evenly pyrolyzed.

[0070] During the flue gas purification analysis and management process, the current flue gas generation situation is determined by the flue gas concentration information and the flue gas emission information. The exhaust management unit conducts real-time comparative analysis of the gas concentration value, and then the linkage control unit makes flue gas emission control. The flue gas purification amount is fed back to adjust the feeding and deflection control during the pyrolysis process, and the relevant startup control is made based on the numerical relationship between the gas concentration value and the gas concentration threshold, ultimately ensuring that the purification end always operates at normal load.
