Abstract
Description
Technical Field
[0001] This utility model relates to the field of organic matter treatment technology, specifically to an organic matter catalytic burner in a solar photovoltaic panel. Background Technology
[0002] During the pyrolysis and calcination process, waste photovoltaic panels may produce a variety of organic compounds due to high temperatures and material decomposition. The specific amount depends on the composition of the photovoltaic panel (such as crystalline silicon modules or thin-film modules) and the processing conditions (temperature, atmosphere, etc.). These organic compounds may incompletely decompose under oxygen-deficient or oxygen-limited conditions to form carbon black.
[0003] A search revealed CN218763410U, a catalytic combustion pyrolysis device for organic matter, relating to the field of pyrolysis equipment. The device includes a pyrolysis furnace body, with a combustion zone and a pyrolysis zone separated by a partition. A feeding assembly is installed on the top of the furnace body, and a stirring assembly is installed inside. The furnace body is placed on the ground via a base. The stirring assembly consists of a stirring motor mounted on the outer wall of the top of the furnace body. The bottom output end of the stirring motor passes through the furnace body shell and is fixedly connected to a stirring column. Multiple stirring rods are fixedly connected to both sides of the stirring column, and each stirring rod has a locking block fixedly connected to its top. Scrapers are locked to both stirring rods via the locking blocks. The partition separates the pyrolysis furnace body into the combustion zone and the pyrolysis zone, reducing the impurity content of the pyrolysis products. Simultaneously, the stirring assembly stirs the organic raw materials and catalyst within the pyrolysis zone, accelerating the internal pyrolysis speed and improving pyrolysis efficiency.
[0004] Although the above-mentioned device separates pyrolysis and combustion, thus improving efficiency, it cannot effectively reduce the oxygen content in the furnace to create an oxygen-deficient condition when pyrolyzing organic matter. Furthermore, it cannot maintain the oxygen concentration under oxygen-deficient conditions during the reaction, preventing the organic matter from undergoing incomplete thermal decomposition to form carbon black under oxygen-deficient or limited conditions.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0034] Please see Figure 1-4 As shown, this utility model is an organic catalytic burner for solar photovoltaic panels, comprising:
[0035] The base plate 100 has a pyrolysis furnace body 200 fixedly connected to its top. The pyrolysis furnace body 200 has an inlet / outlet 210 fixedly provided on one side and a stirring mechanism 300 fixedly connected to the other side. The pyrolysis furnace body 200 and the stirring mechanism 300 are existing structures and will not be explained here.
[0036] The oxygen limiting mechanism includes a nitrogen cylinder 410, a pressure gauge 420, an air supply pipe 430, an air inlet assembly 440, and an air outlet assembly 460.
[0037] Nitrogen cylinder 410 is fixed to the base plate 100, pressure gauge 420 is fixed to the outlet of nitrogen cylinder 410, one end of gas supply pipe 430 is fixedly connected to the end of nitrogen cylinder 410, and the other end of gas supply pipe 430 passes through the side wall of pyrolysis furnace body 200 and is fixedly connected to pyrolysis furnace body 200. Gas inlet assembly 440 is fixed to one side of the lower end of the side wall of pyrolysis furnace body 200, and gas outlet assembly 460 is fixed to the other side of the lower end of the side wall of pyrolysis furnace body 200. Nitrogen cylinder 410... After the nitrogen gas in the pyrolysis furnace body 200 is delivered into the pyrolysis furnace body 200 through the gas supply pipe 430, the air in the pyrolysis furnace body 200 is discharged through the gas outlet component 460, which reduces the oxygen content in the pyrolysis furnace body 200 and creates an oxygen-deficient environment. When the oxygen content in the pyrolysis furnace body 200 decreases due to pyrolysis, the gas pressure in the pyrolysis furnace body 200 decreases. Due to the pressure difference, outside air enters the pyrolysis furnace body 200 through the gas inlet component 440, thereby maintaining the oxygen-deficient environment in the pyrolysis furnace body 200.
[0038] The intake assembly 440 includes a round tube 441, a baffle 442, an intake port 443, a round rod 444, a sealing plate 445, and a spring 446;
[0039] A circular tube 441 is fixedly installed through the side wall of the pyrolysis furnace body 200. A baffle 442 is fixedly connected inside the circular tube 441. An air inlet 443 is opened on the surface of the baffle 442. A circular rod 444 is slidably connected in the middle of the baffle 442. A sealing plate 445 is fixedly connected to the end of the air inlet 443. The two ends of a spring 446 are fixedly connected to the bottom surface of the baffle 442 and the surface of the sealing plate 445, respectively. When oxygen is consumed in the pyrolysis furnace body 200, the gas pressure decreases and a pressure difference is formed between the inside and outside. The large external pressure causes the sealing plate 445 to slide and separate from the end of the circular tube 441, and drives the circular rod 444 to slide, causing the spring 446 to be pulled up. When air is replenished in the pyrolysis furnace body 200, the internal and external pressures become equal. The spring 446 rebounds and causes the sealing plate 445 to stick to the end of the circular tube 441, so that the gas in the pyrolysis furnace body 200 cannot leak from the circular tube 441.
[0040] A gas outlet valve 411 is fixedly connected to the top of the nitrogen cylinder 410. A pressure reducing valve 450 is also fixedly connected to the gas supply pipe 430 and the pressure gauge 420. Opening the gas outlet valve 411 allows the nitrogen in the nitrogen cylinder 400 to be discharged. The pressure reducing valve 450 is a YQD-6 nitrogen pressure reducing valve to prevent excessive pressure from causing an explosion.
[0041] The exhaust component 460 and the intake component 440 have the same structure, but the exhaust component 460 and the intake component 440 are opposite in direction. An oxygen detector 470 is fixedly connected to the curved wall of the pyrolysis furnace body 200. The oxygen detector 470 is a MIC-600 fixed gas detector.
[0042] Working principle: After the waste photovoltaic panels and catalyst are placed into the pyrolysis furnace body 200 through the inlet / outlet 210, the inlet / outlet 210 is closed, and the gas outlet valve 411 is opened to allow nitrogen from the nitrogen cylinder 410 to enter the pressure gauge 420. Then, the pressure reducing valve 450 is slowly opened to prevent excessive pressure from causing an explosion. The nitrogen enters the pyrolysis furnace body 200 through the gas supply pipe 430, discharging the air inside the pyrolysis furnace body 200 through the gas outlet assembly 460, thus reducing the oxygen content inside the pyrolysis furnace body 200 and creating a deflation zone. In an oxygen-deficient environment, when oxygen is consumed inside the pyrolysis furnace 200, causing a decrease in gas pressure and creating a pressure difference between the inside and outside, the high external pressure causes the sealing plate 445 to slide and separate from the end of the circular tube 441, which in turn drives the circular rod 444 to slide, causing the spring 446 to be pulled up. When air is replenished inside the pyrolysis furnace 200, the internal and external pressures become equal, and the spring 446 rebounds, causing the sealing plate 445 to stick to the end of the circular tube 441, preventing gas from leaking from the circular tube 441 inside the pyrolysis furnace 200, thereby maintaining an oxygen-deficient environment in the pyrolysis furnace 200.
[0043] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:
[0044] It also includes a collection mechanism, which includes an outlet pipe 510, a purification box 520, a filter plate 530, an alkaline solution 540, a collection pipe 550, and a gas collection bottle 560.
[0045] The gas outlet pipe 510 is sleeved on the gas outlet assembly 460. The purification box 520 is fixed on the base plate 100. The other end of the gas outlet pipe 510 passes through the purification box 520. The filter plate 530 is inserted into one side of the purification box 520. The alkaline solution 540 is stored on the other side of the purification box 520. The collection pipe 550 is fixed on the other side of the purification box 520. The gas collection bottle 560 is fixed on the base plate 100. The other end of the collection pipe 550 is fixedly connected to the side wall of the gas collection bottle 560. After the reaction in the pyrolysis furnace body 200 is completed, nitrogen is continuously introduced into the pyrolysis furnace body 200 so that the gas generated in the reaction in the pyrolysis furnace body 200 is discharged from the gas outlet assembly 460, enters the purification box 520 through the gas outlet pipe 510, passes through the alkaline solution 540, and then the acidic gas is neutralized and removed. After the toxic gas in the gas is filtered through the gas supply pipe 430, the remaining combustible gas is collected from the collection pipe 550 into the gas collection bottle 560.
[0046] A partition plate 521 is fixedly installed in the middle of the purification chamber 520. The partition plate 521 divides the filter plate 530 into two chambers. There are multiple filter plates 530, which are equidistantly inserted into the left chamber of the purification chamber 520. The alkaline solution 540 is stored in the right chamber of the purification chamber 520. The exhaust pipe 510 rises into the bottom of the alkaline solution 540. A connecting pipe 522 is fixedly connected to the top of the partition plate 521. After the gas enters the bottom of the alkaline solution 540 from the exhaust pipe 510 for neutralization reaction, it enters the left chamber from the connecting pipe 522 and is filtered by the filter plate 530.
[0047] A circular partition 571 is fixedly connected inside the vent pipe 510. Two first circular holes 572 are formed on the surface of the circular partition 571. A motor 573 is fixedly connected to the middle of the circular partition 571. An arc plate 574 is fixedly connected to the power output end of the motor 573. Two second circular holes 575 are symmetrically formed on the side wall of the vent pipe 510. Before pyrolysis, the motor 573 is started to drive the arc plate 574 to rotate, causing the two ends of the arc plate 574 to protrude... First, the first circular hole 572 is blocked, and the groove of the arc plate 574 is aligned with the second circular hole 575. Nitrogen gas is used to expel the air in the pyrolysis furnace body 200 and allow air to enter through the second circular hole 575. During pyrolysis, the motor 573 drives the arc plate 574 to rotate, so that the groove of the arc plate 574 is aligned with the first circular hole 572, and the protrusion of the arc plate 574 blocks the second circular hole 575. Gas in the pyrolysis furnace body 200 enters the purification box 520 through the gas outlet pipe 510.
[0048] Working principle: The starting motor 573 drives the arc plate 574 to rotate, so that the groove of the arc plate 574 is aligned with the first circular hole 572, and the protrusion of the arc plate 574 blocks the second circular hole 575. After the reaction in the pyrolysis furnace body 200 is completed, nitrogen is continuously introduced into the pyrolysis furnace body 200, so that the gas generated in the reaction in the pyrolysis furnace body 200 is discharged from the gas outlet component 460, enters the purification box 520 through the gas outlet pipe 510, passes through the alkaline solution 540, and then the acidic gas is neutralized and removed. After the toxic gas in the gas is filtered through the gas supply pipe 430, the remaining combustible gas is collected from the collection pipe 550 into the gas collection bottle 560. While collecting combustible gas, the toxic gas is prevented from leaking into the air.
