Description

Technical Field

[0001] This invention belongs to the field of waste gas treatment technology, and specifically relates to a catalytic combustion industrial waste gas treatment device. Background Technology

[0002] Industrial emissions often have harmful effects on the environment and human health. Before being released into the atmosphere, they should be treated with purification measures to meet the requirements of emission standards. This process is called waste gas purification. Commonly used waste gas purification methods include absorption, adsorption, condensation and combustion. Catalytic combustion is a typical gas-solid phase catalytic reaction. It uses a catalyst to lower the activation energy of the reaction, allowing it to burn without flame at a lower ignition temperature.

[0003] A search revealed that Chinese Patent Publication No. CN217978830U, published on December 6, 2022, discloses a catalytic combustion device, including a dry filter box, a catalytic desorption chamber, and a combustion chamber. The dry filter box has a fire damper on one side, and a solid filter screen inside the sealed door. An exhaust gas pipe is located above the dry filter box. Three sets of catalytic desorption chambers are located below the exhaust gas pipe. A pipe connects the catalytic desorption chamber to the exhaust gas pipe, and a pressure relief valve is installed at the connection point. A temperature detector is located on one side of the pressure relief valve. A filter gas pipe is located below the catalytic desorption chamber, and a pipe connects the upper end of the filter gas pipe to the catalytic desorption chamber, with a pressure relief valve and a temperature detector also installed at the connection point. The advantages of this invention are: the dry filter box improves the device's lifespan; the catalytic desorption chambers facilitate the adsorption of harmful substances; and the combustion chamber and fan remove harmful substances from the adsorption device, improving catalytic efficiency and reducing energy consumption.

[0004] However, the device still has the following drawbacks:

[0005] Existing waste gas treatment devices typically employ a traditional rectangular straight-cavity filtration structure. After the waste gas enters from one side of the inlet, it forms a typical "piston flow" within the cavity. Most of the airflow rushes directly towards the outlet along the shortest path from the center of the cavity, with only a small portion diffusing towards the activated carbon filling areas on both sides of the cavity. The actual effective residence time of the waste gas within the adsorption chamber is insufficient, preventing the organic components in the waste gas from fully contacting the pores of the activated carbon, thus reducing the filtration effect of industrial waste gas.

[0019] The beneficial effects of this invention are:

[0020] 1. Because the adsorption chamber is semi-annular, the waste gas can increase the contact area with the activated carbon adsorbent through continuous refraction as it passes through. When the adsorption effect of the activated carbon adsorbent decreases, the lower feed screw is rotated first to transfer the activated carbon adsorbent in the adsorption chamber to the return chamber. Then, the upper feed screw is rotated to transfer the activated carbon adsorbent in the feed chamber to the adsorption chamber, thus completing the rapid replacement of the activated carbon adsorbent. At the same time, the lifting screw is rotated to completely transfer the activated carbon adsorbent with decreased adsorption effect to the regeneration chamber. When the lifting screw stops rotating, the activated carbon adsorbent is confined in the spiral channel. When the heated gas passes through the spiral channel, it can uniformly heat and regenerate the activated carbon adsorbent, which not only improves the filtration effect of the treatment device, but also improves the replacement efficiency and regeneration effect of the activated carbon adsorbent particles.

[0021] 2. The second catalytic chamber is filled with granular catalyst, which enhances the contact between the waste gas and the active sites due to its higher specific surface area. This allows for the pretreatment of high-concentration, complex-composition waste gas, decomposing some of the difficult-to-oxidize components and reducing the load on the honeycomb catalyst in the first catalytic chamber. Simultaneously, the honeycomb catalyst is evenly distributed on the top of several sets of rotating plates, and each set of rotating plates has several sets of electrochemical sensors at its bottom. These sensors detect the distribution of waste gas from bottom to top, thus determining the catalytic efficiency of the corresponding honeycomb catalyst. By controlling the independent rotation of several sets of rotating plates, uniform catalytic treatment of the waste gas from bottom to top is ensured. This not only improves the overall lifespan of the catalyst but also enhances the catalytic combustion effect of industrial waste gas.

[0022] 3. When treating industrial waste gas, the filter screen traps paint mist and dust particles. Simultaneously, a pneumatic system drives several sets of hollow blades to rotate. When high-pressure water is supplied to the rotating water supply plate, the water is atomized through nozzles to form a water mist. Under the rotation of the hollow blades, a mist vortex is generated to capture fine particles that the filter screen cannot catch. At the same time, the rotating water supply plate also drives a cleaning rod to clean the filter screen and prevent it from clogging. This improves the interception effect of the treatment device on paint mist and dust particles while enhancing the stability of operation.

[0023] 4. By controlling the baffle plate located in the second catalyst tank to open the corresponding material replacement channel, several sets of material replacement channels are connected to the second catalyst tank. Then, the guide screw is rotated to discharge the catalyst particles in the second catalyst tank through the lower guide screw and replenish the catalyst particles through the higher guide screw. At the same time, the drive structure and the clamp can transfer the honeycomb catalyst in the honeycomb chamber to the auxiliary material replacement mechanism, which facilitates the replacement of the honeycomb catalyst by personnel. This not only improves the working convenience of the treatment device, but also improves the replacement efficiency of the honeycomb catalyst.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0041] This invention provides a catalytic combustion industrial waste gas treatment device, including a base plate 1. For example, as shown... Figure 1 As shown, the top of the base plate 1 is provided with a mounting frame 2 and a stair frame 3; several sets of combined catalytic converters 4 are provided at equal intervals on the mounting frame 2; the bottom of the several sets of combined catalytic converters 4 is connected to an air intake heating pipe 5; a guide pipe 13 is provided on one side wall of the air intake heating pipe 5; the end of the air intake heating pipe 5 away from the combined catalytic converter 4 is connected to a pretreatment mechanism 6; the top of the several sets of combined catalytic converters 4 is connected to an exhaust pipe 9; one end of the exhaust pipe 9 is connected to an air intake pipe 10; the end of the air intake pipe 10 away from the combined catalytic converter 4 is connected to an induced draft fan 11; the other end of the induced draft fan 11 is connected to a tail gas release pipe 12; a storage mechanism 7 is provided on the side of the several sets of combined catalytic converters 4 away from the pretreatment mechanism 6; and an auxiliary material replacement mechanism 8 is provided on the top of the base plate 1.

[0042] When treating industrial waste gas, the pretreatment unit 6 is connected to the industrial waste gas emission port, and then the induced draft fan 11 is started. When the industrial waste gas is emitted, it first passes through the pretreatment unit 6 to intercept paint mist and dust particles in the waste gas, preventing impurities from entering the subsequent units and clogging the catalyst channels. Then, the industrial waste gas is heated to the catalytic temperature in the inlet heating pipe 5. The heated waste gas then enters the combined catalytic unit 4 for catalytic combustion. The treated industrial waste gas is discharged into the atmosphere through the exhaust pipe 9 and the tail gas release pipe 12. At the same time, some of the heated gas is introduced into the pretreatment unit 6 for the regeneration of activated carbon particles. When one or more sets of combined catalytic units 4 malfunction, the industrial waste gas is diverted through the gas guide branch pipe 13 to avoid the fault area.

[0043] For example, such as Figure 3 and Figure 4As shown, the combined catalytic converter 4 includes a first catalytic converter 401; the bottom of the first catalytic converter 401 is connected to a second catalytic converter 402; the bottom of the second catalytic converter 402 is connected to a flow equalization box 403; the top of the first catalytic converter 401 is provided with an exhaust duct 404; a maintenance door 405 is provided on one side wall of the first catalytic converter 401; the bottom of the flow equalization box 403 is connected to the intake heating pipe 5; a flame arrestor 406 and several sets of flow equalization plates 407 are arranged sequentially from bottom to top inside the flow equalization box 403; a baffle 408 is provided at the bottom of the second catalytic converter 402; two sets of pipes are provided on one side wall of the second catalytic converter 402. The catalyst box 402 has a set of material exchange channels 410 on each of its two inner walls; each set of material exchange channels 410 is connected to a corresponding set of pipe channels 409; each set of material exchange channels 410 has a set of baffle plates 411; the catalyst box 401 has several sets of rotating placement plates 412 at equal intervals along the vertical direction; each set of rotating placement plates 412 has several sets of placement slots 413 evenly distributed on it; each set of placement slots 413 has a set of gas guide holes 414 at the bottom; each set of rotating placement plates 412 has several sets of electrochemical sensors evenly distributed at the bottom.

[0044] In the treatment of industrial waste gas, the heated waste gas passes through a flame arrestor 406 and several sets of flow equalization plates 407 before entering the second catalytic chamber 402. The second catalytic chamber 402 is filled with granular catalyst, which enhances the contact between the waste gas and the active sites due to its higher specific surface area. This pretreatment of high-concentration, complex-composition waste gas can decompose some of the difficult-to-oxidize components, reducing the load on the honeycomb catalyst in the first catalytic chamber 401. At the same time, the honeycomb catalyst is evenly distributed on the top of several sets of rotating placement plates 412, and each set of rotating placement plates 412 is equipped with several sets of electrochemical sensors at the bottom to detect the distribution of waste gas from bottom to top, thereby determining the catalytic efficiency of the corresponding honeycomb catalyst. By controlling the independent rotation of several sets of rotating placement plates 412, the waste gas from bottom to top can be uniformly catalyzed, which not only improves the overall service life of the catalyst but also improves the catalytic combustion effect of the industrial waste gas.

[0045] For example, such as Figure 5 , Figure 6 and Figure 7As shown, the pretreatment mechanism 6 includes a filter box 601; an air inlet connecting pipe 602 is provided on one side wall of the filter box 601; a regeneration box 603 is provided on one side wall of the filter box 601; a filter chamber 604 is provided inside the filter box 601; a filter assembly 605 is provided at the connection between the filter chamber 604 and the air inlet connecting pipe 602; an adsorption chamber 606 is connected to the top of the filter chamber 604; the side view cross-section of the adsorption chamber 606 is semi-circular; a set of baffles 607 is provided at both ends of the adsorption chamber 606; a set of material exchange chambers 608 are respectively opened above and below the adsorption chamber 606; each set of material exchange chambers 608... All sides of the 08 are circular in cross-section; the bottom of the upper material exchange chamber 608 is connected to the adsorption chamber 606; the bottoms of both ends of the lower material exchange chamber 608 are connected to the adsorption chamber 606; each set of material exchange chambers 608 is provided with a set of guide screws 609; the regeneration box 603 is provided with a feeding chamber 610 and a return chamber 611 from top to bottom; one end of each of the two sets of guide screws 609 extends into the feeding chamber 610 and the return chamber 611 respectively; a regeneration chamber 612 is provided on one side of the feeding chamber 610 and the return chamber 611; a lifting screw 613 is provided in the regeneration chamber 612; the regeneration chamber 612 is connected to the exhaust pipe 9.

[0046] In the treatment of industrial waste gas, the waste gas first passes through filter assembly 605 to intercept paint mist and dust particles. Then, the waste gas passes through activated carbon adsorbent filled in adsorption chamber 606, where fine particles and some harmful substances in the waste gas are adsorbed. Because adsorption chamber 606 is semi-circular with an arc-shaped top, the contact area between the waste gas and the activated carbon adsorbent is increased through continuous refraction as the waste gas passes through. When the adsorption effect of the activated carbon adsorbent decreases, the feed screw 609 below is first controlled to rotate, transferring the activated carbon adsorbent in adsorption chamber 606 to return chamber 611. Then, the process is controlled... The upper feed screw 609 rotates, transferring the activated carbon adsorbent in the feed chamber 610 to the adsorption chamber 606, thereby completing the rapid replacement of the activated carbon adsorbent. Controlling the rotation of the lifting screw 613 allows for the complete transfer of activated carbon adsorbent with reduced adsorption efficiency to the regeneration chamber 612. When the lifting screw 613 stops rotating, the activated carbon adsorbent is confined within the spiral channel. When the discharged hot gas passes through the spiral channel, it uniformly heats and regenerates the activated carbon adsorbent, improving not only the filtration effect of the treatment device but also the replacement efficiency and regeneration effect of the activated carbon adsorbent particles.

[0047] For example, such as Figure 8 and Figure 9As shown, the filter assembly 605 includes a filter screen 6051; a bearing 6052 is provided at the center of the filter screen 6051; a rotating rod 6053 is sleeved on the inner wall of the bearing 6052; a cleaning rod 6054 and a rotating water supply plate 6055 are respectively provided at both ends of the rotating rod 6053; a number of hollow blades 6056 are arranged in a ring array on the outer wall of the rotating water supply plate 6055; a number of atomizing nozzles 6057 are evenly spaced on the side wall of each set of hollow blades 6056 away from the filter screen 6051.

[0048] When treating industrial waste gas, the filter screen 6051 traps paint mist and dust particles. Simultaneously, a pneumatic mechanism drives several sets of hollow blades 6056 to rotate. This allows water to be supplied under high pressure to the rotating water supply plate 6055, forming a water mist through atomizing nozzles 6057. The rotation of the hollow blades 6056 creates a mist vortex, which captures fine particles that the filter screen 6051 cannot catch. Furthermore, the rotating water supply plate 6055 uses a rotating rod 6053 to drive a cleaning rod 6054 to clean the filter screen 6051, preventing clogging. This improves both the interception effect of the treatment device on paint mist and dust particles and enhances operational stability.

[0049] For example, such as Figure 10 and Figure 11 As shown, the storage mechanism 7 includes a material box 701; a replenishing tray 702 is provided on one side wall of the material box 701; two sets of material exchange pipes 703 are provided on one side wall of the material box 701; each set of material exchange pipes 703 is provided with a set of guide screws; each set of material exchange pipes 703 passes through several sets of corresponding pipe channels 409; several sets of material exchange channels 704 are opened on the outer wall of each set of material exchange pipes 703; each set of material exchange channels 704 is connected to a corresponding set of material exchange channels 410; the material box 701 is equipped with a honeycomb structure. The honeycomb chamber 706 is provided with several sets of placement plates 707 arranged at equal intervals along the vertical direction; the feeding tray 702 is connected to the honeycomb chamber 706; an electric slide 708 is provided on the bottom inner wall of the feeding tray 702; an electric slide 709 is driven to the output end of the electric slide 708; a rotating seat 710 is driven to the output end of the electric slide 709; an electric push rod 711 is driven to the output end of the rotating seat 710; and a clamp 712 is driven to the output end of the electric push rod 711.

[0050] When the catalyst in the combined catalytic mechanism 4 experiences a decrease in catalytic effect, the baffle plate 411 located in the second catalytic chamber 402 is controlled to open the corresponding material replacement channel 410, so that several sets of material replacement channels 704 are connected to the second catalytic chamber 402. Then, the guide screw 2 is controlled to rotate, so that the catalyst particles in the second catalytic chamber 402 can be discharged through the lower guide screw 2, and then new catalyst particles can be replenished through the higher guide screw 2. At the same time, the drive structure, together with the clamp 712, can transfer the honeycomb catalyst in the honeycomb chamber 706 to the auxiliary material replacement mechanism 8, which facilitates the replacement of the honeycomb catalyst by personnel. This not only improves the working convenience of the treatment device, but also improves the replacement efficiency of the honeycomb catalyst.

[0051] For example, such as Figure 12 and Figure 13 As shown, the auxiliary material changing mechanism 8 includes a horizontal moving seat 801; an electric push rod 802 is provided on the top of the horizontal moving seat 801; a rotating seat 803 is drivenly connected to the output end of the electric push rod 802; a rotary feeding disc 804 is drivenly connected to the output end of the rotating seat 803; several sets of placement slots 805 are arranged in a circular array on the side wall of the rotary feeding disc 804; several sets of pressing blocks 806 are elastically movably inserted in a circular array on the inner wall of the placement slots 805; a rotating ring 807 is provided on the outer side of the placement slots 805; several sets of extrusion blocks 808 are arranged in a circular array on the inner wall of the rotating ring 807; each set of extrusion blocks 808 slides and fits against a corresponding set of pressing blocks 806, and the contact surface is an inclined surface.

[0052] The clamp 712 can hold the honeycomb catalyst and transfer it into the corresponding placement tank 805. Then, by controlling the rotating ring 807, it drives several sets of extrusion blocks 808 to rotate. Through the contact slope between the extrusion block 808 and the pressing block 806, several sets of pressing blocks 806 can enter the placement tank 805 to limit the position of the honeycomb catalyst.

[0053] Because the adsorption chamber 606 is semi-annular, the waste gas can increase the contact area with the activated carbon adsorbent through continuous refraction as it passes through. When the adsorption effect of the activated carbon adsorbent decreases, the lower guide screw 609 is rotated first to transfer the activated carbon adsorbent in the adsorption chamber 606 to the return chamber 611. Then, the upper guide screw 609 is rotated to transfer the activated carbon adsorbent in the feeding chamber 610 to the adsorption chamber 606, thus completing the rapid replacement of the activated carbon adsorbent. At the same time, the lifting screw 613 is rotated to completely transfer the activated carbon adsorbent with decreased adsorption effect to the regeneration chamber 612. When the lifting screw 613 stops rotating, the activated carbon adsorbent is confined in the spiral channel. When the heated gas passes through the spiral channel, it can uniformly heat and regenerate the activated carbon adsorbent, which not only improves the filtration effect of the treatment device, but also improves the replacement efficiency and regeneration effect of the activated carbon adsorbent particles.

[0054] Catalytic chamber 2 402 is filled with granular catalyst, which enhances the contact between the exhaust gas and the active sites due to its higher specific surface area. This allows for the pretreatment of high-concentration, complex-composition exhaust gas, decomposing some of the difficult-to-oxidize components and reducing the load on the honeycomb catalyst in the downstream catalytic chamber 1 401. Simultaneously, the honeycomb catalyst is evenly distributed on the top of several sets of rotating placement plates 412, and each set of rotating placement plates 412 has several sets of electrochemical sensors at its bottom. These sensors detect the distribution of exhaust gas from bottom to top, thereby determining the catalytic efficiency of the corresponding honeycomb catalyst. By controlling the independent rotation of several sets of rotating placement plates 412, uniform catalytic treatment of the exhaust gas from bottom to top is ensured. This not only improves the overall service life of the catalyst but also enhances the catalytic combustion effect of industrial exhaust gas.

[0055] When treating industrial waste gas, the filter screen 6051 traps paint mist and dust particles. Simultaneously, a pneumatic mechanism drives several sets of hollow blades 6056 to rotate. This allows water to be supplied under high pressure to the rotating water supply plate 6055, forming a water mist through atomizing nozzles 6057. The rotation of the hollow blades 6056 creates a mist vortex, which captures fine particles that the filter screen 6051 cannot catch. Furthermore, the rotating water supply plate 6055 uses a rotating rod 6053 to drive a cleaning rod 6054 to clean the filter screen 6051, preventing clogging. This improves both the interception effect of the treatment device on paint mist and dust particles and enhances operational stability.

[0056] By controlling the baffle plate 411 located in the catalyst tank 2 402 to open the corresponding material replacement channel 410, several sets of material replacement channels 2 704 are connected to the catalyst tank 2 402. Then, the guide screw 2 is controlled to rotate, so that the catalyst particles in the catalyst tank 2 402 can be discharged through the guide screw 2 at the lower position, and then new catalyst particles can be replenished through the guide screw 2 at the higher position. At the same time, the drive structure and the clamp 712 can transfer the honeycomb catalyst in the honeycomb chamber 706 to the auxiliary material replacement mechanism 8, which facilitates the replacement of the honeycomb catalyst by personnel. This not only improves the working convenience of the treatment device, but also improves the replacement efficiency of the honeycomb catalyst.

[0057] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
