Description

Technical Field

[0001] This utility model relates to the field of incinerator nozzle technology, specifically to an incinerator exhaust gas nozzle. Background Technology

[0002] High-calorific-value waste gas incinerators are mainly used to treat waste gases with high calorific value, odor, high concentration, and high dust content. They can treat almost all compounds in waste gas. They have high VOC purification efficiency, simple operation, low system pressure loss, relatively low fan power consumption, large internal space for easy access and cleaning of sediments, and low maintenance workload. They require a type of waste gas nozzle to deliver waste gas to the incinerator for combustion.

[0003] In existing technologies, the waste gas to be treated is collected or pressurized by an induced draft fan before being introduced into the incinerator for combustion. To ensure safety, safety devices such as flame arresters, water seal tanks, and explosion relief diaphragms are usually installed on the waste gas pipeline. The incinerator body has a through-hole waste gas inlet, to which the waste gas source pipeline is connected. When the temperature inside the furnace reaches the average ignition point of the waste gas components, the waste gas is ignited and begins combustion, reaching the design temperature. When the waste gas volume is small, the through-hole inlet (usually ≤250mm) on the incinerator body can meet the feeding requirements.

[0004] Although the existing technology has many beneficial effects, the following problems still exist: During the use of this device, when the exhaust gas volume is large, the high-calorific-value exhaust gas cannot diffuse quickly, resulting in insufficient residence time, incomplete combustion, and easy irregular flame spray, which may cause flash explosions and affect safety; Secondly, during the use of this device, the existing device generally uses bolts to disassemble and assemble the nozzle, which is not convenient enough and the operation is relatively cumbersome, and needs to be improved. In view of this, we propose an exhaust gas nozzle for incinerators. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0007] Therefore, the purpose of this utility model is to provide an incinerator exhaust gas nozzle that allows high-calorific-value exhaust gas to diffuse rapidly when the exhaust gas volume is large, making combustion more complete. It also facilitates adjusting the exhaust gas flow rate to adapt to different working conditions, makes it convenient to handle easily flammable exhaust gas, and makes the nozzle easier to install and disassemble, and simpler to operate.

The mounting sleeve facilitates the positioning of the nozzle tube and prevents the nozzle tube from being misaligned during insertion, thus avoiding interference with its use.

[0010] In a preferred embodiment of the present invention, the inner diameter of the middle section of the Venturi tube is smaller than that of both ends, the position of the central cone matches the position of the Venturi tube, and the tip of the central cone faces the Venturi tube.

[0013] In a preferred embodiment of the incinerator exhaust gas nozzle of this utility model, the bottom of the incinerator is provided with multiple support blocks, the top opening of the support blocks is arc-shaped, and the support blocks prevent the cylindrical incinerator from rolling and affecting its use.

[0014] In a preferred embodiment of the present invention, an incinerator exhaust gas nozzle is provided at one end of the outer circumference of the nozzle tube, and the side wall of the flange ring is provided with a plurality of connection holes in an annular array.

[0015] 3. Beneficial effects: Compared with the prior art, the beneficial effects of this utility model are: This type of incinerator exhaust gas nozzle drives the swirl plate to rotate through the exhaust gas flow, guiding the exhaust gas to rotate and flow along the swirl channel, changing the exhaust gas combustion state, effectively ensuring the degree of turbulence after exhaust gas combustion, ensuring combustion efficiency, and reducing the carbon monoxide generation rate. When the exhaust gas volume is large, the combustion is more complete. The position of the central cone can be adjusted to change the inner diameter of the venturi tube, making it easy to adjust the exhaust gas flow rate to adapt to different working conditions and convenient for handling easily ignitable exhaust gas. This type of incinerator exhaust gas nozzle uses a spring to drive a moving ring to press and clamp the plate, so that the clamping slot engages with the fixed arc plate, making the nozzle easier to install and remove and simpler to operate.

[0022] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0023] This utility model provides an overall structural schematic diagram of an embodiment of an incinerator exhaust gas nozzle, including: Please see Figures 1-5This embodiment of an incinerator exhaust gas nozzle includes an incinerator 1. A nozzle pipe 2 is snapped onto the side wall of the incinerator 1. A nozzle head 3 is welded to one end of the nozzle pipe 2. An adjustment assembly 4 is welded to the inner circumference of the nozzle pipe 2. The adjustment assembly 4 includes two fixing rings 401. A fixing sleeve 402 is provided at the center of the side wall of the fixing rings 401. The fixing rings 401 are used to prevent the swirl plate 404 from being blown away by the exhaust gas flow and thus detached. A rotating shaft 403 is rotatably connected to the side wall of the fixing sleeve 402. A swirl plate 404 is welded to the outer circumference of the rotating shaft 403. The swirl plate 404 is used to drive the exhaust gas to rotate and flow along the swirl channel, which can change the exhaust gas combustion state and effectively ensure the turbulence degree after exhaust gas combustion, thus ensuring combustion efficiency. A Venturi tube 405 is welded to the inner circumference of the nozzle head 3. The Venturi tube 405 is used to directly change the exhaust gas flow rate, thus enhancing the flame intensity after the exhaust gas is ignited, that is, enhancing the stability and safety of exhaust gas combustion. The bottom of the side wall of the incinerator 1 is welded with... There is a mounting base 406, and a high-temperature resistant cylinder 407 is threadedly connected to the top of the mounting base 406. The mounting base 406 is to make the operation of the high-temperature resistant cylinder 407 more stable. The output end of the high-temperature resistant cylinder 407 is interference-fitted with a connecting rod 408. The connecting rod 408 is used to drive the central cone 409 to move under the drive of the high-temperature resistant cylinder 407. The other end of the connecting rod 408 is welded to the side wall of the central cone 409. The central cone 409 is used to move and adjust the annular gap size of the inner diameter of the venturi tube 405, so as to facilitate the adjustment of the exhaust gas flow rate to adapt to different working conditions. When the size is increased, it is convenient to handle easily flammable exhaust gas. The side wall of the incinerator 1 is welded with a mounting component 5, and the other end of the side wall of the incinerator 1 is welded with an exhaust port 6. The top of the incinerator 1 is welded with an explosion-proof door 7. The high-temperature resistant cylinder 407 is connected to an external air pump through an air pipe. The connecting rod 408 and the central cone 409 are made of 310S matrix + ZrO2 coating, which can withstand 1400℃ to facilitate adaptation to the incinerator environment.

[0024] It is worth noting that, in order to facilitate the installation of the nozzle, the installation component 5 specifically includes an installation sleeve 501. A fixed arc plate 502 is welded to one end of the inner circumference of the installation sleeve 501, and an installation ring 503 is welded to the other end of the inner circumference of the installation sleeve 501. Multiple springs 504 are welded to the side wall of the installation ring 503, and a movable ring 505 is welded to the other end of the springs 504. The movable ring 505 is used to push and squeeze the clamping plate 506 under the action of the springs 504. The clamping plate 506 is welded to the outer circumference of the nozzle tube 2. The clamping plate 506 is used to squeeze the movable ring 505 to move and rotate after the nozzle tube 2 is inserted into the installation sleeve 501. A groove 507 is opened on the side wall of the clamping plate 506. The groove 507 is used to reset and move the clamping plate 506 to clamp the fixed arc plate 502 under the elastic force of the springs 504, thereby enhancing stability and making the installation of the nozzle tube 2 simpler.

[0025] Next, to facilitate the adjustment of the exhaust gas flow rate, specifically, the inner diameter of the middle section of the Venturi tube 405 is smaller than the inner diameters at both ends, and the position of the central cone 409 matches the position of the Venturi tube 405, with the tip of the central cone 409 pointing towards the Venturi tube 405. The Venturi tube 405, with its middle section having a smaller inner diameter than the two ends, facilitates the acceleration of exhaust gas flow, and the central cone 409, with its tip pointing towards the Venturi tube 405, facilitates the precise adjustment of the size of the annular gap in the inner diameter of the Venturi tube 405.

[0026] Meanwhile, to prevent loosening of the splice, specifically, the arc length of the fixed arc plate 502 matches the arc length of the notch of the snap-fit ​​plate 506, and the size of the fixed arc plate 502 matches the size of the snap-fit ​​groove 507. By using the fixed arc plate 502, which matches the arc length of the notch of the snap-fit ​​plate 506, it avoids obstructing the movement of the snap-fit ​​plate 506 into place. By using the snap-fit ​​groove 507, which matches the size of the fixed arc plate 502, it is easier to make the snap-fit ​​between the fixed arc plate 502 and the snap-fit ​​plate 506 more stable and prevent loosening.

[0027] Furthermore, to facilitate improved sealing performance, a sealing ring 508 is fitted onto the inner circumference of the mounting ring 503. The sealing ring 508 is made of fluororubber. The fluororubber sealing ring 508 improves sealing performance, prevents gaps from affecting use, and prevents damage caused by excessively high operating temperatures during incinerator operation. Fluororubber has high temperature resistance and can be used in environments ranging from -30℃ to +250℃. It is also resistant to strong oxidants, oil, acids, and alkalis. According to GB safety standards, the internal temperature of the incinerator is between 760℃ and 1200℃, while the surface temperature of the external shell is typically between 50℃ and 80℃. The sealing ring 508 is located on the external shell, which meets the requirements.

[0028] It is worth noting that, in order to facilitate the support of the incinerator 1, specifically, multiple support blocks 8 are welded to the bottom of the incinerator 1. The top opening of the support block 8 is arc-shaped. The support block 8 with the arc-shaped top opening is convenient to fit the incinerator 1 better and improve the stability of the support.

[0029] Finally, to facilitate connection to the conveying pipeline, specifically, a flange ring 9 is welded to one end of the outer circumference of the nozzle pipe 2. The flange ring 9 has multiple connection holes 10 arranged in a ring array on its side wall. The flange ring 9 with multiple connection holes 10 on its side wall facilitates the connection between the nozzle pipe 2 and the pipeline conveying high-calorific-value exhaust gas.

[0030] In addition, the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods. The device or equipment models mentioned in this article may be as follows: High-temperature resistant cylinder 407: SMC CJ2W.

[0031] Combination Figures 1-5 The specific usage process of an incinerator exhaust gas nozzle according to this embodiment is as follows: 1: When this device is needed to be used as an incinerator exhaust gas nozzle, install nozzle pipe 2, and connect nozzle pipe 2 to the pipeline that transports high-calorific-value exhaust gas through flange ring 9, so as to transport exhaust gas into incinerator 1 for combustion. The exhaust gas flow drives the swirl plate 404 to rotate, so that the exhaust gas rotates and flows along the swirl channel, which can change the exhaust gas combustion state. The exhaust gas is accelerated and enhanced by the venturi tube 405. The high-temperature resistant cylinder 407 is started to drive the connecting rod 408 to move the central cone 409. The exhaust gas flow rate is adjusted by adjusting the inner diameter of the venturi tube 405 and the size of the annular gap. 2: Insert the nozzle tube 2 into the mounting sleeve 501. The snap-fit ​​plate 506 presses the moving ring 505 inward. Rotate the nozzle tube 2 so that the center part of the snap-fit ​​plate 506 corresponds to the fixed arc plate 502. Release the nozzle tube 2. The rebound force of the spring 504 drives the moving ring 505 to move, causing the snap-fit ​​plate 506 to move outward and drive the snap-fit ​​groove 507 to snap into the fixed arc plate 502 to complete the installation.

[0032] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
