Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to an energy-saving and environmentally friendly RTO emergency waste gas treatment device. Background Technology

[0002] Regenerative Thermal Oxidizers (RTOs) are highly efficient devices for treating low- to medium-concentration organic waste gases. Their core principle is heat storage and oxidation reaction. Using heat storage materials such as ceramics, the organic waste gas is preheated to over 800℃. The waste gas is then fully oxidized and decomposed into harmless substances in the combustion chamber, achieving a thermal efficiency exceeding 95% and an organic waste gas removal rate of over 99%. Taking a three-bed RTO as an example, the waste gas circulates between the regenerator chambers via a switching valve, achieving heat recovery. It offers significant advantages, including high efficiency, energy saving, and adaptability to various complex operating conditions. It is widely used in numerous industries such as coating, printing, and chemicals, helping companies meet environmental emission requirements and effectively reduce emissions of pollutants such as VOCs.

[0003] Because current RTO exhaust gas treatment technology has certain requirements on the composition and concentration of exhaust gas, on the one hand, the exhaust gas cannot contain a large amount of dust, particulate matter or sticky substances, otherwise it will easily block the heat storage body or affect the normal operation of the valve, reducing the treatment efficiency and service life of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide an energy-saving and environmentally friendly RTO emergency exhaust gas treatment device to address the aforementioned shortcomings in the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving and environmentally friendly RTO emergency exhaust gas treatment device, comprising: a cylindrical outer cylinder, a conical body connected to the bottom of the cylindrical outer cylinder, a smoke exhaust pipe connected to one end of the cylindrical outer cylinder, an inner cylinder connected to one end of the smoke exhaust pipe, a plurality of small holes on the outer side of the inner cylinder, a cavity provided between the inner cylinder and the cylindrical outer cylinder, and a first collection box connected to the bottom of the conical body.

[0006] Furthermore, a sealing cap is installed on the top of the cylindrical outer cylinder, and a first smoke outlet pipe is connected to the top of the sealing cap.

[0007] Furthermore, the other end of the first smoke outlet pipe is connected to a filter box, and a cloth bag filter is installed inside the filter box.

[0008] Furthermore, a groove is provided on one side of the filter box, and a sliding plate is fitted inside the groove.

[0009] Furthermore, a second collection box is connected to the bottom of the filter box, a pulse controller is installed on the outside of the filter box, and a second smoke outlet pipe is connected to the top of the filter box.

[0010] Furthermore, a fixing seat is provided on the outer side of the cone, a support column is connected to the bottom of the fixing seat, and an anti-slip pad is installed on the bottom of the support column.

[0011] The energy-saving and environmentally friendly RTO emergency exhaust gas treatment device provided by this utility model has the following beneficial effects:

[0012] This invention introduces a method where exhaust gas enters the inner cylinder from the first exhaust pipe, changing the airflow from linear motion to circular motion, forming a rotating airflow that flows downwards in a spiral shape. Larger particles undergo initial separation through small holes in the inner cylinder wall. During the rotation, other particles in the exhaust gas lose their inertia upon contact with the inner cylinder wall and fall along the wall, entering the first collection box. Subsequently, the exhaust gas, after a second separation, enters the filter box through the first exhaust pipe for final filtration by a bag filter.

[0013] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0023] Please see Figures 1-4 An energy-saving and environmentally friendly RTO emergency exhaust gas treatment device includes: a cylindrical outer cylinder 1, a conical body 2 connected to the bottom of the cylindrical outer cylinder 1, a smoke exhaust pipe 7 connected to one end of the cylindrical outer cylinder 1, an inner cylinder 15 connected to one end of the smoke exhaust pipe 7, a number of small holes 17 starting from the outer side of the inner cylinder 15, a cavity 16 provided between the inner cylinder 15 and the cylindrical outer cylinder 1, a first collection box 6 connected to the bottom of the conical body 2, a sealing cover 8 installed on the top of the cylindrical outer cylinder 1, and a first exhaust pipe 9 connected to the top of the sealing cover 8.

[0024] In a further embodiment provided by this utility model, since the bottom of the cylindrical outer cylinder 1 is connected to the conical body 2, and the inner cylinder 15 is also of this shape, after the exhaust gas enters the cylindrical outer cylinder 1 from the exhaust pipe 7 at a certain speed, the airflow changes from linear motion to circular motion, forming a rotating airflow. Most of the airflow flows spirally downwards from the cylindrical body towards the conical body along the inner cylinder 15 wall. Larger particles will be separated for the first time through the small holes 17 opened in the inner cylinder 15 wall and fall into the cavity 16 formed between the inner cylinder 15 and the cylindrical outer cylinder 1. During the rotation process, the particles that have not yet been separated are thrown towards the inner cylinder 15 wall due to their large inertial centrifugal force. Once the particles come into contact with the inner cylinder 15 wall, they lose their inertial force and fall along the inner cylinder 15 wall surface due to the momentum of their downward axial velocity near the inner cylinder 15 wall, entering the first collection box 6, thus completing the second separation. Meanwhile, the rotating and descending airflow continuously flows into the center of the inner cylinder 15 during the descent, forming a centripetal radial airflow. This part of the airflow constitutes a rotating upward vortex. Finally, the gas separated in the second separation is discharged through the first smoke outlet pipe 9, while the sealing cover 8 can prevent external factors from affecting the interior.

[0025] Furthermore, the other end of the first smoke outlet pipe 9 is connected to a filter box 10, a bag filter 19 is installed inside the filter box 10, a slide groove 18 is opened on one side of the filter box 10, a slide plate 13 is fitted inside the slide groove 18, a second collection box 14 is connected to the bottom of the filter box 10, a pulse controller 12 is installed on the outside of the filter box 10, and a second smoke outlet pipe 11 is connected to the top of the filter box 10.

[0026] In a further embodiment provided by this utility model, the gas after the second separation enters the interior of the filter box 10 through the first smoke outlet pipe 9, and then undergoes final filtration through the bag filter 19 connected inside the filter box 10. The tiny particles present in the gas are intercepted by the fibers on the surface of the bag filter 19, thereby completely filtering the gas, which is then discharged through the second smoke outlet pipe 11. When it is necessary to clean the bag filter 19, the slide plate 13 is pulled out from the inside of the slide groove 18 opened on one side of the filter box 10, and the pulse controller 12 is activated to perform pulse cleaning on the bag filter 19.

[0027] Furthermore, a fixing seat 3 is provided on the outer side of the cone 2, and a support column 4 is connected to the bottom of the fixing seat 3. An anti-slip pad 5 is installed on the bottom of the support column 4.

[0028] In a further embodiment provided by this utility model, the fixed base 3 provides support for the cone-shaped body 2. The fixed base 3 and the support column 4 are fixedly connected. The anti-slip pad 5 installed at the bottom of the support column 4 not only increases friction and enhances stability, preventing the equipment from shifting due to vibration, but also absorbs vibration energy and reduces equipment wear.

[0029] In this practical application, the exhaust gas first enters the cylindrical outer cylinder 1 from the exhaust pipe 7 at a certain speed. The airflow changes from linear motion to circular motion, forming a rotating airflow. Most of the airflow flows spirally downwards from the cylindrical body towards the cone along the inner cylinder 15 wall. Larger particles will be separated for the first time through the small holes 17 opened in the inner cylinder 15 wall and fall into the cavity 16 formed between the inner cylinder 15 and the cylindrical outer cylinder 1. During the rotation process, the particles that have not yet been separated are thrown towards the inner cylinder 15 wall due to their large inertial centrifugal force. Once the particles come into contact with the wall of the inner cylinder 15, they lose their inertial force and fall along the wall of the inner cylinder 15 due to the momentum of their downward axial velocity near the wall, entering the first collection box 6, thus completing the second separation. The rotating and descending airflow continuously flows into the center of the inner cylinder 15 during the descent, forming a centripetal radial airflow. This part of the airflow constitutes a rotating upward vortex. Finally, the gas separated in the second separation is discharged through the first smoke outlet pipe 9, while the sealing cover 8 can prevent external factors from affecting the interior. Subsequently, the gas separated in the second separation enters the interior of the filter box 10 through the first smoke outlet pipe 9, and then undergoes final filtration through the bag filter 19 connected inside the filter box 10. The tiny particles in the gas are intercepted by the fibers on the surface of the bag filter 19, thus completely filtering the gas, which is then discharged through the second smoke outlet pipe 11. When it is necessary to clean the bag filter 19, the slide plate 13 is pulled out from the inside of the slide groove 18 opened on one side of the filter box 10, and the pulse controller 12 is activated to perform pulse cleaning on the bag filter 19.

[0030] The foregoing has only described certain exemplary embodiments of this utility model by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of this utility model. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of this utility model.
