Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, specifically to a catalytic CO waste gas treatment device based on a scalable structure and a composite support gradient. Background Technology

[0002] A CO (carbon monoxide) catalytic oxidation reactor is a type of furnace that utilizes a catalyst to promote the oxidative decomposition of pollutants in waste gas. It boasts advantages such as low operating temperature, energy savings, and high removal efficiency, and is widely used in industries such as spraying and petrochemicals. The CO catalytic oxidation reactor uses a catalyst to lower the oxidation temperature of organic matter to a relatively low level, resulting in complete oxidative decomposition and the production of CO2 (carbon dioxide) and H2O (water). This device employs an advanced honeycomb catalyst to catalytically oxidize organic waste gas, degrading toxic and harmful large organic molecules into smaller inorganic molecules such as water and carbon dioxide, thus preventing air pollution.

[0003] In the process of treating CO waste gas, it is necessary to first remove impurities such as particulate matter and oil through operations such as filtration, dust removal, and oil removal. This reduces the probability of particulate matter and other impurities in the CO waste gas clogging the honeycomb catalyst during subsequent catalytic oxidation treatment, thus facilitating continuous treatment of CO waste gas.

[0004] CN222239454U discloses a waste gas pretreatment device for a CO catalytic combustion furnace. The problem raised in the background technology is that most enterprises currently filter organic waste gas after catalytic combustion. This can easily lead to incomplete catalytic combustion of organic waste gas, and the solid particles after catalytic combustion are adsorbed in the catalytic combustion furnace and are difficult to remove, resulting in a reduction in the service life of the combustion furnace.

[0005] Based on existing technologies, the following problems exist: Existing hollow spheres for uniformly distributing CO waste gas are typically installed in fixed or non-fixed configurations. In these configurations, the hollow spheres remain relatively fixed or have limited mobility when subjected to the upward force of the CO waste gas, reducing the effectiveness of uniform CO distribution. Furthermore, over long-term use, a large amount of particles and impurities adhere to the surfaces of the first and second hollow spheres, which cannot be effectively cleaned by the top spray mechanism alone, affecting subsequent waste gas treatment. In addition, existing CO catalytic oxidation reactors can only treat a single waste gas component. If the exhaust gas from upstream units changes, the conventional approach is to add a new waste gas treatment device, which is both costly and space-consuming. Referring to the aforementioned application documents, when treating CO waste gas through spraying, the atomized droplets only directly contact the CO waste gas, failing to evenly disperse the CO waste gas before contacting the atomized droplets, thus reducing the efficiency of particulate matter removal. To address these issues, a catalytic CO waste gas treatment device based on an scalable structure and a composite support gradient is proposed. Summary of the Invention

[0016] This invention provides a catalytic CO waste gas treatment device based on a scalable structure and a composite support gradient. Compared with the prior art, it has the following advantages: 1. This invention enables the first hollow sphere to rotate and move vertically simultaneously via a first processing mechanism. This ensures that the first hollow sphere maintains a stable degree of movement even when subjected to the upward force of CO waste gas, thereby guaranteeing a uniform distribution of CO waste gas. This facilitates contact between CO particles and atomized droplets, improving the treatment effect on CO particles. Furthermore, in conjunction with a second processing mechanism, the rotation and vertical movement of the first hollow sphere simultaneously compresses and moves the second hollow sphere vertically. The staggered arrangement of the first and second hollow spheres enhances the uniformity of CO waste gas dispersion and reduces the probability of undispersed CO waste gas, thus improving the treatment effect.

[0017] 2. The present invention uses the servo motor of the first processing mechanism to synchronously drive the bevel gear disks of the first processing component, the second processing component and the third processing component to rotate, thereby driving multiple first hollow balls to rotate synchronously and move up and down reciprocally, which is convenient for actual operation. The annular plate of the second processing mechanism prevents the edges of the first and second hollow spheres from interlocking, thus avoiding any obstruction of movement between the first and second hollow spheres during rotation. Furthermore, the guide holes reduce the impact on the flow of CO waste gas, facilitating practical treatment.

[0018] 3. The present invention uses a cleaning component to rinse the surfaces of the first hollow sphere and the second hollow sphere. Since the first hollow sphere can rotate, its surface can be thoroughly rinsed. Furthermore, the rotation and reciprocating movement of the first hollow sphere can drive the second hollow sphere to move up and down and deflect, thereby improving the rinsing effect on the second hollow sphere.

[0019] 4. The present invention moves the top plate of the cleaning component up and down, thereby causing the adjusting rod to squeeze the second spring and rotate under the action of the hinge rod, thereby enabling the nozzle to deflect back and forth, improving the rinsing effect on the first hollow ball and the second hollow ball. Furthermore, by the second top rod reciprocatingly squeezing the rubber sleeve and the first water guide pipe, the cleaning liquid or water can be sprayed at different intensities to rinse the first hollow ball, etc., further improving the rinsing effect.

[0020] 5. The honeycomb catalyst in the catalytic oxidation mechanism completely oxidizes and decomposes the CO waste gas, producing CO2 (carbon dioxide) and H2O (water). This degrades toxic and harmful large organic molecules into small inorganic molecules such as water and carbon dioxide, preventing air pollution. Furthermore, the CO waste gas undergoes catalytic oxidation after particulate matter and other impurities are removed by the first and second treatment mechanisms, thus improving the effectiveness of CO waste gas treatment. By setting up a multi-layer catalytic oxidation mechanism, different catalysts can be matched according to the composition of the waste gas. This allows for adaptation to changes in upstream composition without the need for additional waste gas treatment equipment, reducing costs and saving space, thus facilitating practical CO waste gas treatment.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1, please refer to Figure 1 and Figure 2 A catalytic CO waste gas treatment device based on an expandable structure and composite support gradient includes a base 1 and a furnace body 3 fixed on the top of the base 1. It also includes a first treatment mechanism 8 and a second treatment mechanism 9 disposed in the furnace body 3. The first treatment mechanism 8 and the second treatment mechanism 9 cooperate to pre-treat CO waste gas, thereby removing particulate matter from the CO waste gas to assist in subsequent treatment of CO waste gas.

[0025] An air inlet pipe 2 is fixedly provided on the side wall of the furnace body 3 and at the bottom of the third ring 97, an exhaust pipe 4 is fixedly provided on the top of the furnace body 3, and a spraying mechanism 7 is provided on the inner side wall of the furnace body 3 and at the top of the first ring 81. The top of the base 1 is fixedly equipped with an exhaust fan 6, the air inlet end of the exhaust fan 6 is fixedly connected to the exhaust end of the exhaust pipe 4, and the exhaust end of the exhaust fan 6 is fixedly equipped with an air supply pipe 5.

[0026] A side door 10 is hinged to the upper end of the side wall of the furnace body 3. When the side door 10 is closed, it is sealed to the furnace body 3. A catalytic oxidation mechanism 11 is arranged at intervals on the inner side wall of the furnace body 3 and at the side door 10. The catalytic oxidation mechanism 11 includes a mounting frame 113, a frame 112, a wire mesh 114, and a honeycomb catalyst 111. The outer wall of the mounting frame 113 is fixedly connected to the inner side wall of the furnace body 3. The honeycomb catalyst 111 is fixed to the inner wall of the frame 112 by the wire mesh 114. The frame 113 is fixed to the top of the mounting frame 113 by bolts. Thus, after the side door 10 is opened, the honeycomb catalyst 111 can be removed by bolts or the like for easy replacement.

[0027] In implementation, the CO waste gas to be treated is introduced into the furnace body 3 through the air inlet pipe 2. Then, under the action of the exhaust fan 6, the CO waste gas entering the furnace body 3 flows upward through the exhaust pipe 4. During the upward flow of the CO waste gas, the first treatment mechanism 8 and the second treatment mechanism work together to disperse the CO waste gas. This allows for more thorough contact between the liquid and particles in the waste gas under the action of the spraying mechanism 7, improving the separation effect of particulate matter in the CO waste gas and thus enhancing the pretreatment effect of the CO waste gas. This facilitates subsequent treatment of the CO waste gas. The CO waste gas, with particulate matter removed, continues to flow upward along the inside of the furnace body, where the honeycomb catalyst 111 of the catalytic oxidation mechanism 11 causes complete oxidation and decomposition of the CO waste gas, generating CO2 (carbon dioxide) and H2O (water). This process degrades toxic and harmful large-molecule organic matter into small-molecule inorganic substances such as water and carbon dioxide, preventing air pollution. After being treated by the catalytic oxidation unit 11, the CO waste gas enters the gas transmission pipe 5 through the exhaust pipe 4 and the exhaust fan 6, and is then transported to the next treatment stage for further treatment of the CO waste gas.

[0028] By connecting the gas transmission pipe 5 to an external pipeline, the CO waste gas after particulate removal is introduced into subsequent preheating and heat exchange equipment, catalytic combustion reaction equipment, etc., to treat the CO waste gas, thereby realizing the expandable function of the CO waste gas treatment device. Furthermore, by coordinating the first treatment mechanism 8 and the second treatment mechanism, adjustments can be made according to the amount of CO waste gas discharged to support the gradient treatment of CO waste gas.

[0029] With the cooperation of the first treatment unit 8 and the second treatment unit 9, the CO waste gas can be evenly dispersed during the upward flow of the furnace body 3, thereby improving the contact effect between the atomized droplets and the waste gas, and more effectively capturing particulate matter for pretreatment of CO waste gas, which is convenient for subsequent treatment and use of CO waste gas.

[0030] By setting up a multi-layer catalytic oxidation mechanism 11, different catalysts can be matched according to the composition and structure of the waste gas. This allows for adaptation to changes in upstream composition without the need for additional waste gas treatment equipment, reducing costs and saving space, making it convenient for actual CO waste gas treatment. The honeycomb catalyst 111 is fixed to the frame 112 by a wire mesh 114, and the frame 112 is fixed to the top of the mounting frame 113 by bolts, thus installing the honeycomb catalyst 111 inside the furnace body 3. This makes the honeycomb catalyst 111 removable and easy to replace, and the side door 10 provides a windbreak to ensure the airtightness of the side wall of the furnace body 3 and prevent air leakage. The number of catalytic oxidation mechanisms 11 and the type of honeycomb catalyst 111 can be adjusted by those skilled in the art according to the actual needs of waste gas purification, and are not limited here.

[0036] Please see Figure 3 , Figure 4 and Figure 11 The second processing unit 9 includes: The third ring body 97 is fixedly installed on the inner wall of the furnace body 3 and located at the bottom of the first ring body 81. The inner side of the third ring body 97 is provided with a fourth ring body 93, and the inner side of the fourth ring body 93 is provided with a fifth ring body 92. The third ring body 97, the fourth ring body 93 and the fifth ring body 92 are connected by an elastic band 91. The second hollow sphere 94 is rotatably disposed on the top of the fourth ring body 93 and the fifth ring body 92, and is arranged in a ring array. The second hollow sphere 94 and the first hollow sphere 805 are arranged alternately. The outer side of the outer end of the second hollow sphere 94 is fixedly provided with a ring plate 95, and the top of the ring plate 95 is provided with a guide hole 96 arranged in a ring array.

[0037] In practice, as the CO waste gas flows upward along the furnace body 3, it passes through the second hollow sphere 94 and the first hollow sphere 805 of the second treatment mechanism 9 and the first treatment mechanism 8, respectively, so as to disperse the CO waste gas through the hollow spheres. The hollow spheres are existing structures and will not be described in detail here.

[0038] Because existing hollow spheres for uniformly distributing CO waste gas are typically installed in fixed or non-fixed configurations, these methods result in the hollow spheres remaining relatively fixed or having limited mobility when subjected to the upward force of the CO waste gas. This reduces the effectiveness of uniform CO waste gas distribution. Therefore, the first processing mechanism 8 allows the first hollow sphere 805 to rotate and move vertically simultaneously. This ensures that the first hollow sphere 805 maintains a stable degree of movement under the upward force of the CO waste gas, thus guaranteeing uniform CO waste gas distribution. This facilitates contact between CO particles and atomized droplets, improving the treatment effect on CO particles. Furthermore, in conjunction with the second processing mechanism 9, the rotation and vertical movement of the first hollow sphere 805 simultaneously compresses and vertically moves the second hollow sphere 94. The staggered arrangement of the first and second hollow spheres 805 further enhances the uniformity of CO waste gas dispersion and reduces the probability of undispersed CO waste gas, thereby improving the treatment effect.

[0039] When the first hollow ball 805 rotates and moves vertically, the servo motor 85 drives the rotating rod 89 to rotate. The rotating rod 89 drives the first bevel gear 82, the second bevel gear 83, and the third bevel gear 84 to rotate, thereby driving the bevel gear disk 803, the second bevel gear ring, and the third bevel gear ring of the first processing component 80 to rotate. The fourth bevel gear 88 and the fifth bevel gear 87 drive the bevel gear disk 803 of the second processing component 892 and the third processing component 893 to rotate, respectively. When the bevel gear disk 803 rotates, the bevel gear disk 803 drives the outer hexagonal plate 802 to rotate, and the outer hexagonal plate 802 drives the inner hexagonal sleeve 8093 and the first hollow ball 805 to rotate. Simultaneously, when the bevel gear disk 803 rotates, it drives the connecting ring 8098 and the ring-shaped array of pressure rods 8092 to rotate. Since the pressure plate 809 is rotatably connected to the internal hexagonal sleeve 8093 and slidably connected to the top shell 806, the pressure plate 809 does not rotate when the internal hexagonal sleeve 8093 rotates with the external hexagonal plate 802. Furthermore, due to the action of the top arc surface 808 and the bottom arc surface 8094, the pressure rods 8092 can compress the pressure plate 809 when rotating with the bevel gear disk 803. 9 moves downward, thereby causing the internal hexagonal sleeve 8093 to squeeze the first spring 8096 and the telescopic sleeve 807 downward. When the pressure rod 8092 exchanges between the top arc surface 808 and the bottom arc surface 8094, and under the action of the first spring 8096, the internal hexagonal sleeve 8093 and the first hollow ball 805 can move up and down reciprocally while rotating, thereby avoiding restricting the activity of the hollow ball during the upward flow of CO waste gas, so as to improve the uniformity of CO waste gas dispersion.

[0040] The inner hexagonal sleeve 8093 is connected by the bottom ring 8097, and the inner hexagonal sleeve 8093 is elastically pulled by the first spring 8096. This allows the pressure rod 8092 to rotate alternately on the bottom arc surface 8094 and the top arc surface 808, while the first hollow ball 805 rotates and moves up and down reciprocally. Furthermore, by setting up a circular array of bottom arc surface 8094, top arc surface 808 and pressure rod 8092, the uniformity of force on the pressure plate 809 is ensured, thereby ensuring the stability of the first hollow ball 805's up and down reciprocating movement.

[0041] The second mounting ring 8091 is rotatably mounted by the first mounting ring 8095 and the bearing 800, and is slidably connected to the second mounting ring 8091 by the internal hexagonal sleeve 8093. This limits the internal hexagonal sleeve 8093 while allowing it to move vertically and rotate, thus ensuring the stability of the rotation and reciprocating movement of the first hollow ball 805.

[0042] The first servo motor 85 can drive multiple first hollow balls 805 to rotate synchronously and move up and down reciprocally, which is convenient for actual operation and ensures the mobility of the first hollow balls 805. The first spring 8096, the first bevel gear ring and the second bevel gear ring are covered by the telescopic sleeve 807 and the protective cover 894 to reduce the residue of liquid in the first bevel gear ring and other parts, which is convenient for long-term use.

[0043] The first ring 81, the second ring 86, and the plate 891 facilitate the installation of multiple first hollow spheres 805 and the first processing component 80, while ensuring that the CO exhaust gas has space to flow upward, thus avoiding affecting the effect of removing particles from the CO exhaust gas.

[0044] During the rotation and reciprocating movement of the first hollow sphere 805, the first hollow sphere 805 compresses the second hollow sphere 94. Furthermore, due to the connection between the fifth ring body 92 and the fourth ring body 93 via the elastic band 91, the second hollow sphere 94 can reciprocate up and down. In addition, since the second hollow sphere 94 is rotatably connected to the fourth ring body 93 and the fifth ring body 92, the mobility of the second hollow sphere 94 is further improved, enhancing the uniformity of gas dispersion. Moreover, the staggered arrangement of the first hollow sphere 805 and the second hollow sphere 94 reduces the probability of gas leakage.

[0045] The annular plate 95 prevents the side wings of the first hollow ball 805 and the second hollow ball 94 from interlocking, thereby avoiding movement obstruction between the first hollow ball 805 and the second hollow ball 94 during rotation. Furthermore, the guide hole 96 reduces the impact on the flow of CO waste gas, facilitating practical treatment.

[0046] Example 2, please refer to Figure 6 and Figure 7The technical difference between this embodiment and Embodiment 1 is that the cleaning component 804 includes: The top plate 8041 is rotatably mounted on the outer wall of the internal hexagonal sleeve 8093 and located between the first mounting ring 8095 and the first hollow ball 805. The top of the top plate 8041 is fixedly provided with a first push rod 8043 and a second push rod 8042. The first push rod 8043 and the second push rod 8042 are arranged at intervals, and the tops of the first push rod 8043 and the second push rod 8042 are both arc-shaped. The first mounting groove 80494 is located at the bottom of the plate 891. The inner sidewall of the first mounting groove 80494 is rotatably provided with a hinge shaft 8046. An adjusting rod 8045 is fixedly provided on the sidewall of one end of the hinge shaft 8046 located in the first mounting groove 80494. The adjusting rod 8045 is L-shaped and extends to the bottom of the plate 891. A nozzle 8044 is fixedly provided at the bottom of the adjusting rod 8045.

[0047] The cleaning component 804 also includes: The second spring 8047 is fixedly disposed on the top inner wall of the first mounting groove 80494 and arranged at intervals. The bottom of the second spring 8047 is fixedly connected to the top of the adjusting rod 8045. The limiting block 80492 is fixedly installed on the lower end of the inner wall of the first mounting groove 80494 to limit the rotation of the adjusting rod 8045. The first top rod 8043 is sleeved in the limiting block 80492. The rubber plate 80493 is fixedly disposed on the inner wall of the first mounting groove 80494 and fixedly connected to the side wall of the limiting block 80492. The top of the rubber plate 80493 is provided with a through hole for fitting the adjusting rod 8045.

[0048] The cleaning component 804 also includes: The second mounting groove 80491 is opened at the bottom of the plate 891. The second push rod 8042 extends into the second mounting groove 80491. The water inlet end of the nozzle 8044 is fixedly provided with a first water guide pipe 80495, and the first water guide pipe 80495 extends along the inside of the adjusting rod 8045 into the second mounting groove 80491. A rubber sleeve 8049 is fixedly sleeved on the outer wall of the end of the first water guide pipe 80495 located in the second mounting groove 80491. The second water pipe 8048 is fixedly installed at the water inlet end of the first water pipe 80495 and extends along the plate 891 to the outside of the furnace body 3.

[0049] In practical implementation, during long-term use, a large number of particles and impurities adhere to the surfaces of the first hollow sphere 805 and the second hollow sphere 94. The top spray mechanism 7 alone is insufficient for effective cleaning. Therefore, a cleaning pipe is connected externally through the second water guide pipe 8048, allowing cleaning liquid or water to enter the nozzle 8044 via the second water guide pipe 8048 and the first water guide pipe 80495. Since the surfaces of the first hollow sphere 805 and the second hollow sphere 94 are interconnected and mostly porous, the nozzle 8044 effectively rinses their surfaces. The first hollow sphere 805 can rotate, facilitating thorough rinsing of its surface. Furthermore, the rotation and reciprocating movement of the first hollow sphere 805 cause the second hollow sphere 94 to move up and down and deflect, thus improving the rinsing effect on the second hollow sphere 94.

[0050] In addition, when the hexagonal socket 8093 moves up and down and rotates, the top plate 8041 is rotatably connected to the hexagonal socket 8093, thereby driving the top plate 8041 to move up and down. The top plate 8041 drives the first push rod 8043 and the second push rod 8042 to move up and down. When the first push rod 8043 moves upward, it squeezes the horizontal section of the adjusting rod 8045, thereby causing the adjusting rod 8045 to squeeze the second spring 8047 and rotate under the action of the hinge rod, so that the nozzle 8044 can deflect back and forth, improving the rinsing effect on the first hollow ball 805 and the second hollow ball 94. Furthermore, by the second push rod 8042 reciprocatingly squeezing the rubber sleeve 8049 and the first water guide pipe 80495, the cleaning liquid or water can be sprayed at different intensities to rinse the first hollow ball 805, etc., further improving the rinsing effect.
