Abstract
Description
Technical Field
[0001] This invention relates to the field of combustion equipment, and more particularly to an RTO incinerator. Background Technology
[0002] RTO incinerators utilize alternating regenerator and combustion chambers to oxidize and decompose waste gas at high temperatures. The waste gas is first preheated in the regenerator chamber, then enters the combustion chamber for high-temperature combustion. The purified high-temperature gas then releases heat through another regenerator chamber before being discharged, achieving high heat recovery efficiency and waste gas decomposition rate. However, when waste gas enters the RTO incinerator, large particles can easily clog the pores in the regenerator, resulting in low waste gas throughput and abnormally high internal pressure. This accelerates wear on components such as the regenerator and burner, shortening equipment lifespan. Therefore, there is an urgent need for an RTO incinerator that can reduce waste gas clogging of the regenerator. Summary of the Invention
[0003] The purpose of this invention is to provide solutions to one or more technical problems existing in the prior art, and to at least provide a beneficial alternative or create conditions.
[0004] An RTO incinerator according to a first aspect of the present invention includes: a heat storage unit comprising a dust removal shell and heat storage tubes, wherein a waste gas inlet is provided at the top of the dust removal shell, a dust removal section with a gradually decreasing inner diameter is formed inside the dust removal shell, a discharge port communicating with the dust removal section is provided on the bottom side of the dust removal shell, the heat storage tubes extend downward into the dust removal section, the heat storage tubes are filled with a first heat storage body, a fan is provided on the heat storage tubes, the fan is used to drive an upward airflow inside the heat storage tubes, and the heat storage unit comprises at least two units; and a combustion shell disposed at the top of the two heat storage tubes, wherein a burner is disposed inside the combustion shell.
[0005] This technical solution has at least the following beneficial effects: During operation, exhaust gas enters the dust collector shell from an exhaust gas inlet within a heat storage unit. Inside the dust collector shell, it swirls downwards around the outside of the heat storage body. Large particles in the exhaust gas are thrown to the inner wall of the dust collector shell under gravity. As the inner diameter of the dust collector shell gradually narrows downwards, the swirling flow inside the dust collector shell accelerates. Large particles adhere tightly to the inner wall of the dust collector shell and move downwards under gravity, exiting from the discharge port. The airflow enters the heat storage tube at the bottom and travels upwards along the tube through the first heat storage body, exchanging heat with it. The heated exhaust gas then enters the combustion shell, where the burner ignites it to further heat the exhaust gas. High-temperature oxidation transforms the organic matter in the exhaust gas. Carbon dioxide and water eventually enter another interconnected heat storage unit. The first heat storage body in this unit is heated from top to bottom, and the heat is recovered using the first heat storage body. Large particles entering the first heat storage body are blown downwards and fall from the discharge port. The airflow after heat recovery flows from bottom to top in the dust collector shell and is discharged outwards from the exhaust gas inlet. In this way, before heat exchange, the large particles are thrown to the inner wall of the dust collector shell by the centrifugal force provided by the swirling flow, and the large particles are separated from the exhaust gas. This effectively reduces the amount of large particles entering the first heat storage body when the exhaust gas exchanges heat with the first heat storage body. In addition, when the high-temperature gas exchanges heat with the first heat storage body, it can also have the effect of jet cleaning of the first heat storage body, which greatly reduces the risk of clogging of the first heat storage body.
[0006] According to some embodiments of the present invention, the combustion shell is provided with a guide chamber connected to two heat storage tubes and a combustion chamber disposed between the two guide chambers. The burner is located in the combustion chamber. Partition plates are spaced apart along the axial direction of each of the two guide chambers. Multiple guide pipes are connected between two adjacent partition plates. These multiple guide pipes extend obliquely, deviating from the axis of the guide chamber. The multiple guide pipes form multiple airflow channels between the two partition plates. After being heated by heat exchange in the first heat storage body, the exhaust gas enters the guide chamber through these multiple airflow channels before entering the combustion chamber. Because the multiple guide pipes are obliquely inclined, multiple airflows enter the combustion chamber obliquely, forming a swirling flow inside the combustion chamber, improving the flowability of the exhaust gas. When the burner ignites and heats up, the uniformly flowing exhaust gas can undergo sufficient high-temperature oxidation, further improving the exhaust gas decomposition efficiency.
[0007] According to some embodiments of the present invention, the inner diameter of the two ends of the combustion chamber near the guide chamber gradually increases towards the center of the combustion chamber, and the burner is located in the center of the combustion chamber. A transition space of gradually varying size is formed near the two guide chambers of the combustion chamber. This transition space gradually increases towards the center of the combustion chamber. At this point, multiple airflows enter the combustion chamber more smoothly and naturally, which is beneficial for improving the swirling mixing effect. Furthermore, the gradually changing transition space allows for uniform diffusion of the exhaust gas, which is conducive to sufficient high-temperature oxidation with the ignited hot airflow, further improving the exhaust gas decomposition efficiency.
[0008] According to some embodiments of the present invention, the top end of the heat storage tube extends upward beyond the dust removal shell, and a heat collection tube is connected between the combustion shell and the top end of the heat storage tube. A second heat storage body is disposed inside the heat collection tube, and a filter plate is disposed at the connection between the heat collection tube and the heat storage tube. The heat storage tube forms part of the heat exchange within the dust removal shell. Similarly, a part for heat exchange is also formed outside the dust removal shell. Specifically, after the exhaust gas passes through the first heat storage body, it enters the filter plate. After the exhaust gas is further filtered by the filter plate, it enters the second heat storage body of the heat collection tube for heat exchange. The second heat storage body is closer to the combustion chamber and has a higher heat output. In use, the pores inside the second heat storage body are smaller, which is more conducive to heat collection. Furthermore, since the filter plate can further adsorb and filter the exhaust gas, the risk of small particulate matter in the exhaust gas clogging the second heat storage body is reduced, thus extending the service life of the second heat storage body.
[0009] According to some embodiments of the present invention, a dust collection box is provided on the top of the heat storage tube on the side away from the heat collection tube. An opening is provided at the connection between the dust collection box and the heat storage tube. A cover plate is provided on the dust collection box at the opening. A rotary driver is provided on the outside of the dust collection box. The rotary driver drives the top side of the cover plate and the top side of the filter plate to be connected. The filter plate extends downward at an angle away from the dust collection box to the connection angle between the heat collection tube and the heat storage tube. The rotary driver can drive the cover plate and the filter plate to rotate, so that the cover plate rotates into the dust collection box and the filter plate rotates to block the opening. When exhaust gas flows from the heat storage tube to the heat collector tube, the cover plate is in the open position, blocking and sealing the opening, while the filter plate is located at the connection between the heat collector tube and the heat storage tube, which can block and filter the airflow entering the heat collector tube. When the high-temperature airflow flows from the heat collector tube to the heat storage tube, the rotary driver drives the cover plate and filter plate to rotate, so that the cover plate rotates into the dust collection box, while the filter plate blocks the opening. At this time, the filter surface on the filter plate used for adsorption and filtration faces into the dust collection box. When the high-temperature airflow passes through the filter plate, it blows air onto the filter plate, blowing the dust particles adsorbed on the filter surface into the dust collection box, realizing the self-cleaning of the filter plate, which helps to ensure the adsorption effect of the filter plate during long-term use.
[0010] According to some embodiments of the present invention, a baffle frame is provided at the position inside the opening of the ash collection box. When the cover plate is in the opening position, the baffle frame abuts against the side of the cover plate near the heat collection tube. When the cover plate rotates to block the opening, the baffle frame can limit the rotation stroke of the cover plate, which helps to ensure that the cover plate can rotate to the correct position. Furthermore, the mutual contact between the baffle frame and the cover plate can improve the sealing performance of the opening position. Similarly, when the filter plate rotates to block the opening, the baffle frame can block and limit the filter plate.
[0011] According to some embodiments of the present invention, a discharge valve is provided on the bottom side of the ash collection box. When the cover plate closes the opening, the discharge valve can be opened to discharge dust particles from the ash collection box. When the cover plate is rotated into the ash collection box, the discharge valve is closed to prevent high-temperature airflow from flowing out from the discharge valve.
[0012] According to some embodiments of the present invention, a connecting rod is connected between the filter plate and the cover plate. The filter plate and the cover plate are connected as a whole by the connecting rod, which facilitates the rotary driver to drive the filter plate and the cover plate to rotate synchronously. When the cover plate is in the closed state, the exhaust gas flows through the filter plate, and the pressure on the filter plate can be transmitted to the cover plate through the connecting rod, so that the cover plate can more tightly block and seal the opening.
[0013] According to some embodiments of the present invention, a dust collection hopper is provided on the bottom side of the discharge port of the dust collector housing. The dust and waste collected inside the dust collector housing can fall into the dust collection hopper for easy recycling.
[0014] According to some embodiments of the present invention, an air inlet pipe is provided on the outer side of the dust collector housing at the location of the exhaust gas inlet, and the air inlet pipe extends tangentially along the inner wall of the dust collector housing. The air inlet pipe is connected to an external exhaust gas emission device. When the exhaust gas enters the dust collector housing through the air inlet pipe, it can flow along the inner wall of the dust collector housing, better forming a swirling flow inside the dust collector housing, thereby improving the separation effect of large particulate matter in the exhaust gas.

The various technical features in this invention can be combined interactively without contradicting each other.
[0020] Reference Figure 1 According to a first aspect of the present invention, an RTO incinerator includes: a heat storage unit comprising a dust removal shell 11 and a heat storage tube 12, wherein the top of the dust removal shell 11 is provided with an exhaust gas inlet, the dust removal shell 11 has a dust removal section with a gradually decreasing inner diameter inside, the bottom side of the dust removal shell 11 is provided with a discharge port communicating with the dust removal section, the heat storage tube 12 extends downward into the dust removal section, the heat storage tube 12 is filled with a first heat storage body 121, and a fan 122 is provided on the heat storage tube 12 for driving an upward airflow inside the heat storage tube 12. At least two heat storage units are provided. In practical applications, an external exhaust device can also be directly installed or connected at the exhaust gas inlet to extract the gas inside the dust removal shell 11 to the discharge port; and a combustion shell disposed at the top of the two heat storage tubes 12, wherein a burner 3 is disposed inside the combustion shell.
[0021] In this RTO incinerator, during operation, exhaust gas enters the dust collector shell 11 through an exhaust gas inlet in a heat storage unit. Inside the dust collector shell 11, it swirls downwards around the outside of the heat storage body. Large particles in the exhaust gas are thrown against the inner wall of the dust collector shell 11 under gravity. As the inner diameter of the dust collector shell 11 gradually narrows downwards, the swirling flow inside the dust collector shell 11 accelerates. Large particles adhere tightly to the inner wall of the dust collector shell 11 and move downwards under gravity, exiting from the discharge port. The airflow enters the heat storage tube 12 at its bottom and travels upwards along the heat storage tube 12 through the first heat storage body 121, exchanging heat with it. The heated exhaust gas then enters the combustion chamber, where the burner 3 ignites it to further heat the exhaust gas. Through high-temperature oxidation, the organic matter in the exhaust gas is converted into carbon dioxide. The gas, along with water, finally enters another interconnected heat storage unit. The first heat storage body 121 within this unit is heated from top to bottom, utilizing the first heat storage body 121 to recover heat. Large particles entering the first heat storage body 121 are blown downwards and fall from the discharge port. The recovered heat airflow flows upwards within the dust collector shell 11 and is discharged outwards from the exhaust gas inlet. In this way, before heat exchange, the centrifugal force provided by the swirling flow throws large particles onto the inner wall of the dust collector shell 11, separating them from the exhaust gas. This effectively reduces the amount of large particles entering the first heat storage body 121 during heat exchange. Furthermore, the high-temperature gas also acts as a jet cleaner on the first heat storage body 121 during heat exchange, greatly reducing the risk of blockage.
[0022] In order to more fully mix the exhaust gas with the high-temperature airflow when it is discharged into the combustion shell, in this embodiment, the combustion shell is provided with a flow guide chamber 21 connected to the two heat storage tubes 12 respectively, and a combustion chamber 22 disposed between the two flow guide chambers 21. The burner 3 is located in the combustion chamber 22. The two flow guide chambers 21 are respectively provided with partition plates 211 at intervals along the axial direction of the flow guide chambers 21. Multiple flow guide pipes 212 are connected between two adjacent partition plates 211. The multiple flow guide pipes 212 extend obliquely along the axis of the flow guide chambers 21 respectively. Multiple guide pipes 212 form multiple airflow channels between two partition plates 211. After the exhaust gas is heated by heat exchange in the first heat storage body 121, it enters the guide chamber 21 and then enters the combustion chamber 22 through multiple airflow channels. Since the multiple guide pipes 212 are inclined along the axis of the guide chamber 21, multiple airflows enter the combustion chamber 22 at an angle, forming a swirling flow inside the combustion chamber 22, which improves the flowability of the exhaust gas in the combustion chamber 22. When the burner 3 is ignited and heated, the uniformly flowing exhaust gas can be fully oxidized at high temperature, further improving the exhaust gas decomposition efficiency.
[0023] Furthermore, the inner diameter of the combustion chamber 22 near both ends of the guide chamber 21 gradually increases towards the center of the combustion chamber 22, and the burner 3 is located in the center of the combustion chamber 22. A transition space of gradually changing size is formed near the two guide chambers 21 in the combustion chamber 22. This transition space gradually increases towards the center of the combustion chamber 22. At this point, multiple airflows enter the combustion chamber 22 more smoothly and naturally, which is beneficial for improving the swirling mixing effect. Furthermore, the gradually changing transition space allows for uniform diffusion of the exhaust gas, which is conducive to sufficient high-temperature oxidation with the ignited hot airflow, further improving the exhaust gas decomposition efficiency.
[0024] To further improve heat recovery efficiency, in this embodiment, the top end of the heat storage tube 12 extends upward from the dust removal shell 11, and a heat collection tube 4 is connected between the combustion shell and the top end of the heat storage tube 12. A second heat storage body 41 is provided inside the heat collection tube 4, and a filter plate 51 is provided at the connection between the heat collection tube 4 and the heat storage tube 12. The heat storage tube 12 forms part of the heat exchange within the dust collector shell 11. Similarly, a part for heat exchange is also formed outside the dust collector shell 11. Specifically, after the exhaust gas passes through the first heat storage body 121, it enters the filter plate 51. After the filter plate 51 further filters the exhaust gas, it enters the second heat storage body 41 of the heat collection tube 4 for heat exchange. The second heat storage body 41 is closer to the combustion chamber 22 and has a higher heat output. In use, the pores inside the second heat storage body 41 are smaller, which is more conducive to heat collection. Furthermore, since the filter plate 51 can further adsorb and filter the exhaust gas, the risk of small particulate matter in the exhaust gas clogging the second heat storage body 41 is reduced, thus extending the service life of the second heat storage body 41.
[0025] Furthermore, such as Figure 2As shown, a dust collection box 52 is provided on the top of the heat storage tube 12 on the side away from the heat collection tube 4. An opening 53 is provided at the connection between the dust collection box 52 and the heat storage tube 12. A cover plate 54 is provided on the dust collection box 52 at the opening 53. A rotary driver 55 is provided on the outside of the dust collection box 52. The rotary driver 55 drives the top side of the cover plate 54 and the top side of the filter plate 51 to be connected. The filter plate 51 extends downward at an angle away from the dust collection box 52 to the connection angle between the heat collection tube 4 and the heat storage tube 12. The rotary driver 55 can drive the cover plate 54 and the filter plate 51 to rotate, so that the cover plate 54 rotates into the dust collection box 52 and the filter plate 51 rotates to cover the opening 53. In practical applications, the rotary driver 55 can be a drive motor or a rotary cylinder. When exhaust gas flows from heat storage pipe 12 to heat collection pipe 4, cover plate 54 is located at opening 53, blocking and sealing opening 53, while filter plate 51 is located at the connection between heat collection pipe 4 and heat storage pipe 12, which can block and filter the airflow entering heat collection pipe 4; when high-temperature airflow flows from heat collection pipe 4 to heat storage pipe 12, rotary driver 55 drives cover plate 54 and filter plate 51 to rotate, so that cover plate 54 rotates into dust collection box 52, while filter plate 51 blocks opening 53. At this time, the filter surface on filter plate 51 used for adsorption and filtration faces into dust collection box 52. When high-temperature airflow passes through filter plate 51, it will blow air onto filter plate 51, blowing the dust particles adsorbed on the filter surface into dust collection box 52, realizing self-cleaning of filter plate 51, which is conducive to ensuring the adsorption effect of filter plate 51 during long-term use.
[0026] To improve the sealing and blocking effect of the cover plate 54 and filter plate 51 on the opening 53, in this embodiment, a baffle frame 56 is provided on the ash collection box 52 located inside the opening 53. When the cover plate 54 is located in the opening 53 position, the baffle frame 56 abuts against the side of the cover plate 54 closest to the heat collection tube 4. When the cover plate 54 rotates to block the opening 53, the baffle frame 56 can limit the rotation stroke of the cover plate 54, which helps to ensure that the cover plate 54 can rotate into place. Furthermore, the mutual contact between the baffle frame 56 and the cover plate 54 can improve the sealing performance of the opening 53. Similarly, when the filter plate 51 rotates to block the opening 53, the baffle frame 56 can block and limit the filter plate 51.
[0027] In order to promptly discharge dust particles from the dust collection box 52, a discharge valve 57 is provided on the bottom side of the dust collection box 52 in this embodiment. When the cover plate 54 closes the opening 53, the discharge valve 57 can be opened to discharge dust particles from the dust collection box 52. When the cover plate 54 is rotated into the dust collection box 52, the discharge valve 57 is closed to prevent high-temperature airflow from flowing out from the discharge valve 57.
[0028] In some embodiments, a connecting rod 58 connects the filter plate 51 and the cover plate 54. The filter plate 51 and the cover plate 54 are connected as one unit by the connecting rod 58, which facilitates the rotary driver 55 to drive the filter plate 51 and the cover plate 54 to rotate synchronously. When the cover plate 54 is closed to the opening 53, the exhaust gas flows through the filter plate 51, and the pressure on the filter plate 51 can be transmitted to the cover plate 54 through the connecting rod 58, making the cover plate 54 more tightly block and seal the opening 53.
[0029] In some embodiments, a dust collection hopper 6 is provided on the bottom side of the discharge port of the dust collector 11. The dust and waste collected in the dust collector 11 can fall into the dust collection hopper 6 for easy recycling.
[0030] In some embodiments, an air inlet pipe 13 is provided on the outer side of the dust collector housing 11 at the exhaust gas inlet, and the air inlet pipe 13 extends tangentially along the inner wall of the dust collector housing 11. The air inlet pipe 13 is connected to an external exhaust gas emission device. When exhaust gas enters the dust collector housing 11 through the air inlet pipe 13, it can flow along the inner wall of the dust collector housing 11, better forming a swirling flow inside the dust collector housing 11, thereby improving the separation effect of large particulate matter in the exhaust gas.
