Description

Technical Field

[0001] This invention relates to the field of waste gas separation technology, and more specifically to an RTO inlet gas separation device for pretreatment of high-concentration waste gas. Background Technology

[0002] In the field of industrial waste gas treatment, regenerative thermal oxidizers (RTOs) are widely used for treating high-concentration organic waste gases due to their high heat recovery efficiency and pollutant decomposition capabilities. However, RTOs have strict requirements for inlet gas quality; solid particles and liquid impurities entrained in the waste gas can seriously affect their operational stability and service life. Existing waste gas pretreatment technologies still have many shortcomings in adapting to the inlet gas requirements of RTOs.

[0003] Existing waste gas pretreatment devices mostly use simple filtration, gravity settling, or conventional cyclone separation to remove impurities. However, the separation precision and efficiency are insufficient to meet the demands of treating high-concentration waste gas. For smaller solid particles and atomized liquid impurities, conventional equipment cannot achieve efficient retention. These impurities, after entering the RTO with the waste gas, adhere to the surface of the heat storage medium's channels, gradually forming deposits and clogging the channels. This blockage significantly reduces heat exchange efficiency, leading to a substantial increase in RTO energy consumption. It also affects the uniform distribution of waste gas within the chamber, causing localized overheating or incomplete combustion, thus reducing pollutant decomposition efficiency.

[0004] Existing pretreatment devices lack adaptability and adjustment capabilities, making it difficult to match the dynamic fluctuations in waste gas flow rate and impurity content in industrial production. When the waste gas flow rate increases sharply or the impurity concentration rises, the device's separation load exceeds the design threshold, and the impurity penetration rate increases significantly. When the waste gas flow rate decreases, insufficient airflow velocity easily occurs, failing to generate effective separation power, resulting in incomplete impurity settling. This rigid structural design cannot achieve adaptive adjustment of separation parameters, making the pretreatment effect unstable and unable to continuously provide qualified intake gas for the RTO.

[0005] Existing equipment also suffers from high maintenance costs and poor operational continuity. Because the separation components are prone to clogging due to impurities, frequent shutdowns for disassembly and cleaning are required, increasing labor costs and disrupting the waste gas treatment process, thus affecting the continuity of industrial production. Some units use an integrated design for the separation components, requiring complete disassembly for cleaning or replacement, further extending downtime. Furthermore, unseparated liquid impurities entering the RTO will rapidly vaporize at high temperatures, generating instantaneous pressure fluctuations, increasing safety risks during equipment operation, and potentially causing chamber vibration or seal failure in severe cases. Summary of the Invention

[0011] Furthermore, the cooperating element also includes:

[0013] Furthermore, the cooperating element also includes:

[0014] The return spring is fixed at one end to the wind deflector and at the other end to the end cap ring; the sealing cover is fixed to the separation cover; and the return torsion spring is fixed to the second sleeve.

[0029] The above-described solution of the present invention has at least the following beneficial effects:

[0030] This invention maintains a small initial gap between the first and second spiral guide plates, which can adaptively adjust according to changes in the amount of exhaust gas passing through. When the amount of exhaust gas passing through the converging tube is large, the thrust exerted by the exhaust gas on the baffle plate is greater, resulting in a longer displacement distance of the baffle plate, which in turn pushes the gap between the first and second spiral guide plates to a larger size. When the amount of exhaust gas passing through the converging tube is small, the thrust exerted by the exhaust gas on the baffle plate is weakened, the displacement distance of the baffle plate is shortened, and the gap between the first and second spiral guide plates is correspondingly reduced. This adaptive adjustment structure can effectively avoid the problem of poor centrifugal separation of solid particles, liquids, and gases due to insufficient downward spiral flow velocity of the exhaust gas after entering the separation cylinder when the amount of exhaust gas is small. By automatically matching the gap between the first and second spiral guide plates with the flow rate of the exhaust gas entering the converging tube, it can ensure that the exhaust gas always maintains a suitable flow velocity between the two guide plates, preventing the flow velocity from being too fast or too slow and affecting the separation effect.

[0047] like Figures 1 to 13 As shown, an embodiment of the present invention provides an RTO inlet gas separator for high-concentration waste gas pretreatment, comprising: an impurity box 1 and a support frame 2 disposed on the impurity box 1, and further comprising:

[0052] The cooperating component 7 also includes: a sealing ring 7015, fixed on the second hydraulic cylinder 7010; a sealing cylinder 7016, one end of which is fixed on the wind baffle 705, and the other end is slidably sleeved on the second hydraulic cylinder 7010; a sealing groove 7017, which is formed on the end of the sealing cylinder 7016 near the second hydraulic cylinder 7010; and a sealing ring 7018, which is fixedly sleeved in the sealing groove 7017.

[0053] The cooperating component 7 also includes: a return spring 7019, one end of which is fixed to the wind deflector 705 and the other end of which is fixed to the end sealing ring 7015; a sealing cover 7020, which is fixed to the separation cover 4; and a return torsion spring 7021, which is fixed to the second sleeve 6.

[0055] Specifically, the cooperating component 7 achieves adaptive adjustment of the spacing between the spiral guide plates through hydraulic transmission and the elastic reset structure; the closed cylinder 7016 and the sealing ring 7018 work together to ensure sealing performance; the reset spring 7019 and the reset torsion spring 7021 provide reverse reset force; and the limit ring 7024 restricts the piston sliding stroke to ensure precise and controllable transmission.

[0056] In another preferred embodiment of the present invention, the power component 8 includes: a motor frame 801 fixed on the separation cover 4; a power motor 802 fixed inside the motor frame 801; a first transmission shaft 803, one end of which is rotatably mounted on the separation cover 4 and the other end of which is fixed on the power motor 802; a second transmission shaft 804 rotatably mounted on the separation cover 4; a first transmission gear 805 fixed on the first transmission shaft 803; a second transmission gear 806 fixed on the second transmission shaft 804 and meshing with the first transmission gear 805; and a power gear ring 807 fixedly sleeved on the first sleeve 5 and meshing with the second transmission gear 806.

[0058] The power component 8 also includes: a synchronizing gear ring 8011, fixed on the second sleeve 6; a synchronizing gear plate 8012, fixed on the guide rod 809; an electromagnet 8013, fixed on the guide plate 808; and a permanent magnet 8014, fixed on the synchronizing gear plate 8012.

[0059] Specifically, the power component 8 adopts a gear transmission and electromagnetic clutch structure to provide power for the synchronous rotation of the spiral guide plate; the motor frame 801 fixes the power motor 802, and the power motor 802 drives the first transmission gear 805 to rotate through the first transmission shaft 803, and drives the first sleeve 5 to rotate through the meshing of the second transmission gear 806 and the power gear ring 807; the guide plate 808 provides sliding guidance for the guide rod 809; when the electromagnet 8013 is energized, it attracts the permanent magnet 8014, which drives the synchronous gear plate 8012 to mesh with the synchronous gear ring 8011, so that the first sleeve 5 and the second sleeve 6 rotate synchronously; after the power is cut off, the guide spring 8010 drives the synchronous gear plate 8012 to reset and disengage, realizing the on and off control of power transmission.

[0060] In another preferred embodiment of the present invention, the sewage discharge component 9 includes: a sewage pump 901, fixed on the impurity tank 1; a main sewage discharge pipe 902, one end of which is fixed on the sewage pump 901 and the other end of which extends into the impurity tank 1; an auxiliary sewage discharge pipe 903, fixed on the sewage pump 901; and a first flange 904, fixed on the end of the auxiliary sewage discharge pipe 903 away from the sewage pump 901.

[0061] The sewage discharge component 9 also includes: a sewage discharge support plate 905, fixed inside the impurity box 1; a sliding rod 906, fixed inside the impurity box 1; a sewage discharge push plate 907, slidably sleeved on the sliding rod 906; a sewage discharge motor 908, fixed on the impurity box 1; a threaded rod 909, one end of which is rotatably mounted on the sewage discharge support plate 905, and the other end of which is rotatably mounted on the impurity box 1; and a bevel gear set 9010, with the input bevel gear fixed on the sewage discharge motor 908 and the output bevel gear fixed on the threaded rod 909.

[0062] Specifically, the sewage discharge component 9 adopts a structure combining pump suction and pusher plate pushing to improve sewage discharge efficiency; the sewage pump 901 draws sewage from the impurity box 1 through the sewage main pipe 902 and discharges it through the sewage auxiliary pipe 903, and the first flange 904 facilitates connection to the external sewage pipeline; the sewage motor 908 changes the transmission direction through the bevel gear set 9010, drives the threaded rod 909 to rotate, drives the sewage pusher plate 907 to slide along the sliding rod 906, and pushes the residual sewage at the bottom of the impurity box 1 toward the inlet of the sewage main pipe 902; the sewage support plate 905 provides rotational support for the threaded rod 909 to ensure smooth and efficient pushing.

[0063] The inlet pipe 13, the accelerating pipe 14, the tapering pipe 15, and the disassembly pipe 18 are fastened together with flanges and bolts to ensure the sealing and structural stability of each pipe connection. The disassembly pipe 18 is specifically used to connect to the exhaust gas source. After the exhaust gas is pretreated by this device, it is precisely connected to the exhaust gas inlet of the regenerative thermal oxidizer through the separation pipe 12 and the second flange 17, forming a complete exhaust gas treatment flow path.

[0064] After the exhaust gas enters the converging tube 15 from the disassembly pipe 18, the airflow thrust acts on the baffle plate 705, driving the baffle plate 705 to move towards the intake pipe 13. During the displacement of the baffle plate 705, the gap between the edge of the baffle plate 705 and the inner wall of the converging tube 15 gradually increases with the displacement. Accompanying the displacement of the baffle plate 705, the baffle plate 705 compresses the return spring 7019, and simultaneously drives the first piston 703 and the first hydraulic rod 704 to move into the first hydraulic cylinder 702. The squeezing action of the first piston 703 pushes the hydraulic oil inside the first hydraulic cylinder 702 into the hydraulic main pipe 706. The hydraulic oil flows along the hydraulic main pipe 706 to the hydraulic hose 7014, and then is injected into the hydraulic system through the hydraulic hose 7014. The second hydraulic cylinder 7010; the volume of hydraulic oil in the second hydraulic cylinder 7010 gradually increases, and the resulting thrust pushes the second piston 7011 and the second hydraulic rod 7012 to extend out of the second hydraulic cylinder 7010. The second hydraulic rod 7012 drives the cooperating gear plate 7013 to make linear displacement; the displacement of the cooperating gear plate 7013 drives the cooperating gear 707 to rotate through tooth meshing. The rotation of the cooperating gear 707 drives the second sleeve 6 to rotate synchronously. During the rotation of the second sleeve 6, a torsional effect is generated on the reset torsion spring 7021. During this process, the first spiral guide plate 10 remains in a fixed state, and the second spiral guide plate 11 rotates with the second sleeve 6, thereby gradually increasing the distance between the first spiral guide plate 10 and the second spiral guide plate 11.

[0065] When the baffle plate 705 moves, it simultaneously drives the closed cylinder 7016 to slide along the outer wall of the second hydraulic cylinder 7010. The sealing groove 7017 and the return spring 7019 are both set on the closed cylinder 7016. The two work together to achieve sealing and isolation between the baffle plate 705 and the internal area of ​​the closed cylinder 7016, preventing exhaust gas leakage from affecting the transmission efficiency. When the exhaust gas stops entering the converging tube 15, the elastic return force of the return spring 7019 and the torsional return force of the return torsion spring 7021 work together to drive the second spiral guide plate 11 back to the initial position.

[0066] The rotation direction of the second sleeve 6 causes the distance between the first spiral guide plate 10 and the second spiral guide plate 11 to gradually increase, and the one-way slide 7025 is in a locked state, which can twist the reset torsion spring 7021.

[0067] The first spiral guide plate 10 and the second spiral guide plate 11 initially maintain a small gap, which can be adaptively adjusted according to changes in the amount of exhaust gas passing through. When the amount of exhaust gas passing through the converging pipe 15 is large, the thrust of the exhaust gas on the baffle plate 705 is greater, causing the baffle plate 705 to move a longer distance, thereby pushing the gap between the first spiral guide plate 10 and the second spiral guide plate 11 to a larger size. When the amount of exhaust gas passing through the converging pipe 15 is small, the thrust of the exhaust gas on the baffle plate 705 is weakened, the displacement distance of the baffle plate 705 is shortened, and the first spiral guide plate 10... The spacing between the first spiral guide plate 10 and the second spiral guide plate 11 is adjusted to be smaller. This adaptive adjustment structure can effectively avoid the problem of poor centrifugal separation of solid particles, liquid and gas caused by insufficient spiral downward flow velocity after the exhaust gas enters the separation cylinder 3 when the exhaust gas volume is small. By automatically matching the spacing between the first spiral guide plate 10 and the second spiral guide plate 11 with the flow rate of the exhaust gas entering the converging tube 15, it can ensure that the exhaust gas always maintains a suitable flow velocity between the first spiral guide plate 10 and the second spiral guide plate 11, and prevent the flow velocity from being too fast or too slow, which would affect the separation effect.

[0068] When the flow rate is too slow, the centrifugal force on the solid particles and liquids carried by the exhaust gas is insufficient, and they cannot overcome the viscosity of the airflow to be thrown towards the inner wall of the separation cylinder 3. Some fine impurities will pass directly through the channel between the first spiral guide plate 10 and the second spiral guide plate 11 with the airflow, resulting in incomplete separation. The unseparated impurities enter the separation gas pipe 12 and flow into the regenerative thermal oxidizer with the clean gas, affecting the operation of subsequent equipment. When the flow rate is too fast, the airflow will form a vortex between the first spiral guide plate 10 and the second spiral guide plate 11, which will disrupt the stable spiral flow. Some impurities that have been thrown towards the inner wall of the separation cylinder 3 will be re-entrained into the airflow by the vortex. At the same time, the excessively fast airflow will also shorten the residence time of impurities in the separation area, reduce the probability of separation between impurities and airflow, and also lead to a decrease in the separation effect.

[0069] The exhaust gas, after being regulated by the converging pipe 15, enters the accelerating pipe 14. After its flow velocity is increased in the accelerating pipe 14, it flows into the inlet pipe 13. The edge of the inlet pipe 13 and the separation cylinder 3 are designed to be tangential. With the guidance of the tangential air intake, the exhaust gas ejected from the inlet pipe 13 forms a stable spiral downward flow along the inner wall of the separation cylinder 3. During the flow of the exhaust gas, it travels along the channel between the first spiral guide plate 10 and the second spiral guide plate 11. Under the action of centrifugal force, the solid particles and liquid in the exhaust gas are thrown towards the inner wall of the separation cylinder 3. The separated clean gas enters from the lower inlet of the separation pipe 12, flows upward along the inside of the separation pipe 12 and flows out from the upper outlet, and is finally transported to the regenerative thermal oxidizer for further treatment.

[0070] During the long-term waste gas separation process, solid particles and liquids thrown against the inner wall of the separation cylinder 3 by centrifugal force will mix with each other and gradually adhere to the inner wall of the separation cylinder 3 to form scale. At this time, the power motor 802 and electromagnet 8013 can be started. After the electromagnet 8013 is energized, it generates magnetic force, which pushes the permanent magnet 8014 and the synchronous toothed plate 8012 to move towards the synchronous toothed ring 8011, so that the synchronous toothed plate 8012 and the synchronous toothed ring 8011 are precisely engaged. When the synchronous toothed plate 8012 moves, it drives the guide rod 809 to slide along the guide trajectory of the guide plate 808. During the sliding process, the guide rod 809 compresses the guide spring 8010. When the electromagnet 8013 stops working, the elastic restoring force of the guide spring 8010 pushes the permanent magnet 8014 and the synchronous toothed plate 8012 to reset, so that the synchronous toothed plate 8012 and the synchronous toothed ring 8011 are disengaged.

[0071] After the power motor 802 starts, it drives the first transmission shaft 803 to rotate. The rotation of the first transmission shaft 803 drives the first transmission gear 805 to rotate synchronously. The first transmission gear 805 and the second transmission gear 806 transmit power through tooth meshing, driving the second transmission shaft 804 and the second transmission gear 806 to rotate. The second transmission gear 806 meshes with the power gear ring 807, driving the power gear ring 807 to rotate. The rotation of the power gear ring 807 in turn drives the first sleeve 5 to rotate. The first sleeve 5 drives the second transmission shaft 804 and the synchronous gear ring 8011 through the meshing synchronous tooth plate 8012. The sleeve 6 rotates synchronously, and the synchronous rotation of the first sleeve 5 and the second sleeve 6 drives the first spiral guide plate 10 and the second spiral guide plate 11 to rotate together. The rotation of the first spiral guide plate 10 and the second spiral guide plate 11 generates a downward pushing force, pushing the solid particles and liquid mixture on the inner wall of the separation cylinder 3 downward. At the same time, the continuous rotation of the first spiral guide plate 10 drives the scraper plate 16 to rotate synchronously. The scraper plate 16 scrapes off the remaining solid particles and liquid mixture by sticking to the inner wall of the separation cylinder 3. The scraped mixture falls into the impurity box 1 for collection.

[0072] During the synchronous rotation of the first sleeve 5 and the second sleeve 6, the cooperating gear 707 will rotate accordingly. At this time, the cooperating gear 707 and the cooperating tooth plate 7013 will slide relative to each other and disengage, which will not interfere with the synchronous rotation of the first sleeve 5 and the second sleeve 6, ensuring the smooth progress of the cleaning process. In the synchronous rotation direction of the first sleeve 5 and the second sleeve 6, the one-way slide 7025 is in a sliding state, avoiding the restriction of the return torsion spring 7021.

[0073] When the amount of solid particles and liquid mixture collected in the impurity tank 1 reaches a certain level, the sewage pump 901 and sewage motor 908 are started to perform sewage discharge. The sewage pump 901 draws the mixture in the impurity tank 1 to the sewage auxiliary pipe 903 through the sewage main pipe 902, and finally discharges it from the device through the sewage auxiliary pipe 903. At the same time, the sewage motor 908 rotates, driving the threaded rod 909 to rotate. The threaded rod 909 drives the sewage push plate 907 to move towards the sewage main pipe 902 through the threaded transmission. The sewage push plate 907 slides smoothly along the guide trajectory of the sliding rod 906, pushing the residual mixture at the bottom of the impurity tank 1 towards the inlet of the sewage main pipe 902, ensuring that the sewage is discharged completely without residue.

[0074] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
