Description

Technical Field

[0001] This utility model relates to the field of waste gas technology, specifically to a regenerative combustion device that resists silicon blockage. Background Technology

[0002] A regenerative thermal ignition (RTO) device introduces organic waste gas into a heat storage chamber where heat energy has been retained from the previous cycle. The waste gas is heated in the heat storage chamber and then introduced into a combustion chamber where it is oxidized and burned with oxygen. The resulting high-temperature exhaust gas is then discharged into another heat storage chamber, where it absorbs heat energy through a heat storage device before being discharged again, forming a cycle.

[0003] The prior art patent document CN115371063A discloses a regenerative thermal ignition device for silicon-containing organic waste gas. This device uses an H13-grade HEPA filter installed in the gas collection chamber for filtration. It works in conjunction with the waste gas pipe, exhaust pipe, and backflushing pipe to filter the inlet and outlet air. The H13-grade HEPA filter is used to remove PM2.5, and the overall filtration efficiency for particles larger than PM2.5 exceeds 99.9%. In addition, it has built-in H13 filter paper, which has a filtration efficiency of more than 99.7% for particles larger than PM0.3. The particulate matter in the waste gas is intercepted by the H13-grade HEPA filter, reducing the probability of silica nucleation and growth, thereby reducing the amount of silica on the inner surface of the heat storage chamber.

[0004] The aforementioned existing technology uses an installation method where the mounting block is inserted into the groove. During long-term use, the mounting block is prone to loosening or even falling out of the groove due to factors such as vibration and airflow impact, affecting the filtration effect and failing to meet people's needs. Therefore, we need a regenerative combustion device that is resistant to silicon blockage. Utility Model Content

[0005] The purpose of this invention is to provide a regenerative combustion device that is resistant to silicon blockage, which solves the problem in the prior art where the installation method of inserting the installation block into the groove is prone to loosening or even falling out of the groove during long-term use due to factors such as vibration and airflow impact, thus affecting the filtration effect.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A regenerative combustion device for preventing silicon blockage includes a combustion chamber, a burner installed on the outer wall of the combustion chamber, a regenerative chamber provided at the top of the combustion chamber, a filter assembly provided on the inner wall of the regenerative chamber, and a discharge assembly provided at the bottom of the combustion chamber. The filter assembly includes a slot, a guide block is fixedly connected to the inner wall of the heat storage chamber, and a filter frame is slidably connected to the outer wall of the guide block. The inner wall of the filter frame has a guide groove, and the inner wall of the guide groove has a circular groove. A spring is fixedly connected to the inner wall of the circular groove, and a round head is fixedly connected to one end of the spring. A filter screen is fixedly connected to the inner wall of the filter frame, and a sealing ring is provided on the inner wall of the filter frame. A fixed handle is fixedly connected to the outer wall of the filter frame. The discharge assembly includes a discharge cylinder, and a transparent plate is fixedly connected to the inner wall of the discharge cylinder. A threaded cap is threadedly connected to the bottom of the discharge cylinder, and a round handle is fixedly connected to the outer wall of the threaded cap. A sealing gasket is provided on the inner wall of the threaded cap.

[0007] Preferably, the number of heat storage chambers is three, and the three heat storage chambers are arranged at equal distances on the combustion chamber.

[0008] Preferably, the heat storage chamber is connected to the filter frame via a slot to form a sliding structure, and the inner wall of the slot is in contact with the outer wall of the filter frame.

[0009] Preferably, there are two guide blocks, and the two guide blocks are symmetrically arranged in the heat storage chamber.

[0010] Preferably, the filter frame forms a sliding structure with the guide groove and the guide block, and the inner wall of the guide groove is in contact with the outer wall of the guide block.

[0011] Preferably, one end of the round head extends into the round groove and connects with the spring, and the inner wall of the round groove fits against the outer wall of the round head.

[0012] Preferably, the inner wall shape and size of the threaded cap match the outer wall shape and size of the sealing gasket, and the inner wall of the threaded cap fits into the outer wall of the sealing gasket.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are: 1. This utility model is equipped with a slot, guide block, filter frame, guide groove, circular groove, spring, round head, filter screen, sealing ring, and fixing handle. When installing the filter frame, the filter frame is inserted into the slot along the guide block. The cooperation between the guide block and the guide groove ensures accurate installation of the filter frame and prevents displacement. After the filter frame is installed in place, the round head is pressed against the guide block by the elastic force of the spring, making the installation of the filter frame more stable and enhancing the stability of the filter frame under conditions such as vibration and airflow impact. It effectively prevents the filter frame from loosening or even coming off, ensuring that the filter screen continuously and stably filters particulate matter in the exhaust gas, reducing the probability of silica nucleation and growth, thereby reducing the amount of silica adhering to the inner surface of the heat storage chamber and improving the device's anti-silicon clogging ability.

[0014] 2. This utility model is equipped with a feeding cylinder, a transparent plate, a threaded cap, a round handle, and a sealing gasket. Impurities generated during combustion in the combustion chamber are collected through the feeding cylinder. The transparent plate allows operators to observe the accumulation of impurities in the feeding cylinder in real time for timely cleaning. When cleaning is required, the sealing gasket ensures the sealing of the feeding cylinder when the threaded cap is tightened, preventing leakage of internal impurities or escape of exhaust gas. The threaded cap is unscrewed through the round handle, making it easy to clean the impurities in the feeding cylinder and avoid affecting the performance of the device due to the accumulation of impurities.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] like Figure 1-4 As shown, a regenerative combustion device for preventing silicon blockage includes a combustion chamber 1, a burner 2 installed on the outer wall of the combustion chamber 1, a regenerative chamber 3 provided on the top of the combustion chamber 1, a filter assembly 4 provided on the inner wall of the regenerative chamber 3, and a discharge assembly 5 provided on the bottom of the combustion chamber 1. The filter assembly 4 includes a slot 401. A guide block 402 is fixedly connected to the inner wall of the heat storage chamber 3, and a filter frame 403 is slidably connected to the outer wall of the guide block 402. A guide groove 404 is opened on the inner wall of the filter frame 403, and a circular groove 405 is opened on the inner wall of the guide groove 404. A spring 406 is fixedly connected to the inner wall of the circular groove 405, and a round head 407 is fixedly connected to one end of the spring 406. A filter screen 408 is fixedly connected to the inner wall of the filter frame 403, and a sealing ring 409 is provided on the inner wall of the filter frame 403. A fixed handle 410 is fixedly connected to the outer wall of the filter frame 403. The discharge assembly 5 includes a discharge cylinder 501, and a transparent plate 502 is fixedly connected to the inner wall of the discharge cylinder 501. A threaded cover 503 is threadedly connected to the bottom of the discharge cylinder 501, and a round handle 504 is fixedly connected to the outer wall of the threaded cover 503. A sealing gasket 505 is provided on the inner wall of the threaded cover 503.

[0019] Through the above technical solution, when installing the filter frame 403, the filter frame 403 is inserted into the slot 401 along the guide block 402. The cooperation between the guide block 402 and the guide groove 404 ensures accurate installation of the filter frame 403 and prevents displacement. After the filter frame 403 is installed in place, the round head 407 is pressed against the guide block 402 by the elastic force of the spring 406, making the installation of the filter frame 403 more stable. This enhances the stability of the filter frame 403 under conditions such as vibration and airflow impact, effectively preventing the filter frame 403 from loosening or even coming out, ensuring that the filter screen 408 continuously and stably filters particulate matter in the exhaust gas and reduces silica. The probability of nucleation and growth is increased, thereby reducing the amount of silica adhering to the inner surface of the heat storage chamber 3 and improving the device's resistance to silicon blockage. Impurities generated during combustion in the combustion chamber 1 are collected through the feed cylinder 501. The transparent plate 502 allows operators to observe the accumulation of impurities in the feed cylinder 501 in real time for timely cleaning. When cleaning is required, the sealing gasket 505 ensures the sealing of the feed cylinder 501 when the threaded cover 503 is tightened, preventing leakage of internal impurities or escape of exhaust gas. The threaded cover 503 can be unscrewed through the round handle 504 to easily clean the impurities in the feed cylinder 501, avoiding the impact of impurity accumulation on the device's performance.

[0020] Specifically, there are three heat storage chambers 3, and the three heat storage chambers 3 are arranged at equal distances on the combustion chamber 1.

[0021] Through the above technical solution, the combustion chamber 1 and the heat storage chamber 3 are equipped with an anti-oxidation silicon ceramic coating, which makes it difficult for silicon particles to adhere and easy to be discharged with the flue gas.

[0022] Specifically, the heat storage chamber 3 forms a sliding structure with the filter frame 403 through the slot 401, and the inner wall of the slot 401 is in contact with the outer wall of the filter frame 403.

[0023] The above technical solution enhances the connection between the filter frame 403 and the slot 401, making it easier for the filter frame 403 to be inserted into the heat storage chamber 3 through the slot 401. The operation is simple, with few steps, and is easy to install and disassemble.

[0024] Specifically, there are two guide blocks 402, and the two guide blocks 402 are symmetrically arranged in the heat storage chamber 3.

[0025] With the above technical solution, by setting two guide blocks 402, when the filter frame 403 is slidably installed on the guide blocks 402 through the guide groove 404, the two guide blocks 402 support the filter frame 403, making the filter frame 403 more stable.

[0026] Specifically, the filter frame 403 forms a sliding structure with the guide block 402 through the guide groove 404, and the inner wall of the guide groove 404 is in contact with the outer wall of the guide block 402.

[0027] The above technical solution facilitates the installation of the filter frame 403 on the two guide blocks 402 via the guide groove 404, making the filter frame 403 slide more stably on the two guide blocks 402 during sliding installation.

[0028] Specifically, one end of the round head 407 extends into the round groove 405 and connects with the spring 406, and the inner wall of the round groove 405 fits against the outer wall of the round head 407.

[0029] With the above technical solution, when the filter frame 403 slides onto the guide block 402, the outer wall of the guide block 402 presses against the round head 407, and the round head 407 moves stably in the circular groove 405, pushing the spring 406 to compress, so that the round head 407 moves more stably in the circular groove 405.

[0030] Specifically, the inner wall shape and size of the threaded cap 503 match the outer wall shape and size of the sealing gasket 505, and the inner wall of the threaded cap 503 fits into the outer wall of the sealing gasket 505.

[0031] With the above technical solution, when the threaded cap 503 is threaded into the feed cylinder 501, one end of the feed cylinder 501 abuts against the sealing gasket 505. The sealing gasket 505 enhances the sealing between the feed cylinder 501 and the threaded cap 503, preventing impurities from leaking out.

[0032] In use, when it is necessary to disassemble the filter frame 403 to clean the filter screen 408 after prolonged use, pull the fixing handle 410. The fixing handle 410 moves the filter frame 403, pulling it out of the slot 401, thereby cleaning or replacing the filter screen 408 on the filter frame 403. During installation, insert the filter frame 403 into the slot 401. The filter frame 403 slides on the guide block 402 via the guide groove 404. The outer wall of the guide block 402 presses against the round head 407. The round head 407 moves stably within the round groove 405, pushing the spring 406 to compress. After compression, the spring 406 rebounds, pushing the round head 407 against the guide block 402. After the filter frame 403 is slidably installed in place, the filter frame... The sealing ring 409 on 403 fits tightly against the slot 401, enhancing the sealing performance and preventing gas leakage from the connection between the filter frame 403 and the slot 401. The filter frame 403 is easy to install and remove, and convenient to use. Impurities generated during combustion in the combustion chamber 1 are collected through the feed cylinder 501. The operator can observe the accumulation of impurities in the feed cylinder 501 in real time through the transparent plate 502 for timely cleaning. When cleaning is required, the threaded cover 503 is unscrewed through the round handle 504 to easily clean the impurities in the feed cylinder 501, avoiding the impact of impurity accumulation on the device performance. This completes all the work. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
