Description

Technical Field

[0001] This application relates to the field of RTO incinerator technology, and in particular to a dust blowing device for the regenerator of an RTO incinerator. Background Technology

[0002] As a key piece of equipment for industrial waste gas treatment, the heat exchange efficiency of the heat storage medium of the RTO incinerator directly affects the incineration effect and energy utilization rate. However, during long-term operation, the heat storage medium is prone to dust accumulation due to particulate matter in the waste gas. This not only reduces heat exchange efficiency and increases energy consumption, but also aggravates internal wear and tear and causes malfunctions and shutdowns. Traditional dust cleaning designs mostly adopt a single airflow blowing or manual cleaning mode, which lacks the ability to coordinate the operation of blowing and sweeping, making it difficult to remove both loose dust and stubborn dust.

[0003] A search revealed an existing patent (publication number: CN219607114U) that discloses a dust purging device for the regenerator of an RTO incinerator, relating to the field of RTO incinerator technology. This device solves the problem of long dust cleaning cycles in RTO incinerator regenerators. It includes a compressed air tank located on the outside of the regenerator ceramic wall, connected to a solenoid valve, which in turn is connected to a blowpipe. The blowpipe passes through the regenerator ceramic wall and is positioned above the regenerator. A purging nozzle is connected to the end of the blowpipe. Compressed air from the compressed air tank enters the blowpipe, and the compressed gas passes through the purging nozzle to purge dust from the regenerator, reducing the frequency of RTO incinerator shutdowns for maintenance, eliminating safety accidents caused by RTO regenerator blockage, and reducing the workload of operators. During the development of this application, the inventors discovered the following problems with the existing technology:

[0004] Existing dust blowing devices mostly rely on single airflow blowing or manual cleaning methods, lacking a coordinated operation mechanism of blowing and sweeping, making it difficult to remove stubborn dust, resulting in incomplete dust cleaning coverage and serious residue.

[0005] Therefore, a dust blowing device for the regenerator of an RTO incinerator is proposed to address the aforementioned technical issues. Utility Model Content

[0006] To address the aforementioned problems, this application provides a dust purging device for the regenerator of an RTO incinerator. This application provides a dust purging device for the regenerator of an RTO incinerator, employing the following technical solution:

[0007] A dust purging device for an RTO incinerator regenerator includes a dust collection mechanism, a cleaning mechanism, a furnace body, and a cleaning door. The cleaning door is installed on the side of the furnace body via a lotus leaf, and the dust collection mechanism is installed on the side of the furnace body away from the cleaning door via a clamp. One end of the dust collection mechanism penetrates through the side wall of the furnace body, and the penetration is fixed by a sealing gasket. The cleaning mechanism is provided on the upper part of the inner wall of the furnace body, and the cleaning mechanism and the furnace body are connected by a bearing, and a sealing sleeve is installed at the bearing connection.

[0008] The blowing mechanism includes a connecting component, a blowing head component, and a rotating component. The blowing head component is mounted on the side of the connecting component via a flange. The rotating component is mounted on the outer diameter surface of the connecting component. The connecting component and the rotating component are interference-fitted. The sweeping mechanism includes a driving component and a transmission component. The transmission component is mounted on the outer diameter surface of the driving component. Part of the connection between the driving component and the transmission component is a threaded connection, and the other part is a sliding connection.

[0009] By adopting the above technical solutions, the multi-seal design effectively improves the sealing performance of the device, reduces energy waste and dust pollution, and extends the service life of vulnerable parts such as bearings.

[0010] Preferably, the connection assembly includes a connector pipe, a solenoid valve, and a connecting pipe, wherein the connecting pipe is threaded onto the side of the connector pipe, and the solenoid valve is flanged onto the side of the connecting pipe away from the connector pipe.

[0011] By adopting the above technical solutions, the threaded and flanged connection method is reliable in sealing and easy to disassemble and assemble, which facilitates the maintenance of the air circuit. The solenoid valve enables the automated control of the purging process, and the purging timing can be adjusted according to the dust accumulation, thereby improving the ease of operation and reducing manual intervention.

[0012] Preferably, the blow head assembly includes a blow pipe, a connecting hose, and a blow nozzle, wherein the connecting hose is threadedly installed on the side of the blow pipe, and the blow nozzle is threadedly installed on the side of the connecting hose away from the blow pipe.

[0013] By adopting the above technical solutions, the flexibility of the connecting hose expands the purging coverage area, which can cope with the dust accumulation in the complex structure of the heat storage body. The purging nozzle increases the local purging pressure and the dust removal degree that is in contact with the bottom of the furnace body is higher.

[0014] Preferably, the rotating assembly includes a first motor, a rotating shaft, and a limiting ring, wherein the rotating shaft is mounted on the side of the first motor via a coupling, and the limiting ring is welded onto the top of the rotating shaft.

[0015] By adopting the above technical solution, the first electric motor provides stable power, and the rotary purging method has a wider coverage area compared with the fixed purging method.

[0016] Preferably, the drive assembly includes a second motor, a threaded rod, and guide rods, wherein the threaded rod is mounted on the side of the second motor via a coupling, and a set of guide rods is provided on each side of the threaded rod.

[0017] By adopting the above technical solution, the combination of the second motor and the threaded rod can adjust the moving speed and stroke of the transmission component. The guide rod effectively prevents the transmission component from deviating, improves the stability of the cleaning process, and avoids incomplete cleaning due to movement deviation.

[0018] Preferably, the transmission assembly includes a threaded sleeve plate, a connecting plate, and a dust removal plate, wherein the connecting plate is welded to the lower part of the threaded sleeve plate, and the dust removal plate is welded to the side of the connecting plate.

[0019] By adopting the above technical solution, the threaded sleeve and threaded rod work together to drive the dust collector plate, resulting in smooth linear movement and uniform cleaning force, which can effectively remove stubborn dust.

[0020] 1. Compared with existing technologies, this RTO incinerator regenerator dust blowing device significantly improves the ability to remove dust inside the furnace by first peeling and concentrating the dust inside the furnace and then deeply cleaning it through a blowing and sweeping mechanism. The blowing mechanism is connected to an external air source through a connecting component, and the air path is controlled by a connecting pipe and a solenoid valve. After the gas flows through the blow pipe, the blowing angle is flexibly adjusted by the connecting hose. Finally, the airflow is compressed through the blowing nozzle to form a high-pressure jet, which can quickly peel off loose dust on the surface of the regenerator. At the same time, the first motor of the rotating component drives the rotating shaft to rotate. Through the stable linkage between the limiting ring and the connecting component, the blowing head component is driven to rotate and blow, ensuring that the dust is concentrated in the same direction and avoiding dispersion and residue. The sweeping mechanism drives the dust removal plate to make close contact with the surface of the regenerator through the connecting plate, and specifically peels off stubborn dust accumulation, effectively making up for the shortcomings of simple airflow blowing in cleaning attached dust.

[0021] 2. Compared with existing technologies, this RTO incinerator regenerator dust blowing device uses a hinged door installed on the side of the furnace body. Operators can periodically open the door to clean the furnace, fundamentally solving the problem of repeated dust accumulation inside the furnace. After the blowing mechanism gathers loose dust and the sweeping mechanism removes stubborn dust, all the cleaned dust will form a concentrated accumulation inside the furnace. At this time, the dust can be directly removed by opening the door, avoiding dust residue in the corners of the furnace, secondary re-flying, or re-adhering to the surface of the regenerator.

The cleaning door 4 is installed on the side of the furnace body 3 via a hinge for easy dust collection and cleaning. The blowing mechanism 1 is installed on the other side of the furnace body 3 using a ferrule, and the through-hole is fixed with a sealing gasket to prevent gas leakage or dust overflow during blowing. The cleaning mechanism 2 is connected to the upper inner wall of the furnace body 3 via a bearing. A sealing sleeve is installed at the bearing to ensure rotational flexibility and isolate dust from the bearing, ensuring long-term stable operation of the mechanism.

[0031] Reference Figure 1 and Figure 3 The connecting assembly 5 includes a connector pipe 10, a solenoid valve 11, and a connecting pipe 12. The connecting pipe 12 is threaded onto the side of the connector pipe 10, and the solenoid valve 11 is flanged onto the side of the connecting pipe 12 away from the connector pipe 10. The connector pipe 10 is used to connect to an external air source, the connecting pipe 12 extends the air path, and the solenoid valve 11 acts as an air path switch to control the flow of purging gas. All components are connected by threads or flanges to ensure the air path is sealed and to prevent gas leakage that could lead to insufficient purging pressure.

[0032] Reference Figure 2 and Figure 3 The blower assembly 6 includes a blow pipe 13, a connecting hose 14, and a blow nozzle 15. The connecting hose 14 is threadedly installed on the side of the blow pipe 13, and the blow nozzle 15 is threadedly installed on the side of the connecting hose 14 away from the blow pipe 13. The blow pipe 13 serves as the main air passage, and the connecting hose 14 can flexibly adjust the blowing angle to blow the dust in the heat storage body in one direction.

[0033] Reference Figure 2 and Figure 3 The rotating assembly 7 includes a first motor 16, a rotating shaft 17, and a limiting ring 18. The rotating shaft 17 is mounted on the side of the first motor 16 via a coupling. The limiting ring 18 is welded onto the top of the rotating shaft 17. The rotating assembly 7 uses the first motor 16 as a power source and drives the rotating shaft 17 to rotate via the coupling. The rotating shaft 17 is linked with the connecting assembly 5 to realize the rotation and blowing of the blow head assembly 6. The limiting ring 18 is fixed to the top of the rotating shaft 17 by welding, thus fixing the blow head assembly 6 and the rotating shaft 17.

The connecting plate 23 is welded to the bottom of the threaded sleeve plate 22, and the dust removal plate 24 is welded to the side of the connecting plate 23. The transmission assembly 9 cooperates with the threaded rod 20 of the drive assembly 8 through the threaded sleeve plate 22 to convert the rotational motion of the threaded rod 20 into the linear motion of the threaded sleeve plate 22, which in turn drives the dust removal plate 24 to move synchronously through the connecting plate 23.

[0036] The working process of this application is as follows: The connecting plate 23 is fixed to the dust removal plate 24 by welding to ensure the structural strength during cleaning. The dust removal plate 24 directly contacts the surface of the heat storage body to peel off the accumulated dust. The external air source is connected through the connector pipe 10 in the connecting assembly 5, and transmitted to the solenoid valve 11 through the connecting pipe 12. After the solenoid valve 11 is opened, the air path is opened, and the gas flows through the blow pipe 13 and enters the connecting hose 14. Finally, the airflow is compressed through the blow nozzle 15 to form a high-pressure blow airflow. At the same time, the first motor 16 of the rotating assembly 7 is started, and the rotating shaft 17 is driven to rotate through the coupling. The limit ring 18 ensures that the rotating shaft 17 and the connecting assembly 5 are stably linked, thereby driving the blow head assembly 6 in the blowing mechanism 1 to rotate and blow. The connecting hose 14 flexibly adjusts the blowing angle to blow the dust on the surface of the heat storage body in the furnace body 3 in the same direction. When the blowing mechanism 1 has collected all the dust, After completion, the drive component 8 of the sweeping mechanism 2 is started, and the second motor 19 drives the threaded rod 20 to rotate through the coupling. The guide rods 21 on both sides of the threaded rod 20 provide stable guidance for the transmission component 9. The threaded sleeve plate 22 cooperates with the threaded rod 20 to convert the rotational motion into linear motion. The dust removal plate 24 is driven to move synchronously through the connecting plate 23. The dust removal plate 24 directly contacts the surface of the heat storage body and peels off the stubborn dust. During the blowing and cleaning process, the furnace body 3 ensures the sealing performance through the sealing gasket and sealing sleeve to avoid gas leakage and dust overflow. Finally, the collected dust is cleaned uniformly through the cleaning door 4 installed on the side hinge of the furnace body 3, realizing the removal of dust inside the furnace body 3.
