Description
Technical Field
[0001] The present invention relates to the technical field of waste gas treatment environmental protection equipment, and in particular to a composite industrial organic waste gas treatment device based on plasma and thermal storage oxidation. Background Art
[0002] With the continuous development of the economy and society, environmental protection issues have begun to receive attention from all sectors of society. Industrial waste gas needs to be treated until it meets national standards before it can be discharged. Because organic waste gas generated by industrial production usually contains multiple components of toxic and harmful organic and inorganic substances, which are harmful to the human body and the environment and will pollute the atmosphere, the composite industrial organic waste gas treatment technology of plasma and regenerative thermal oxidation is a synergistic process that combines low-temperature plasma (NTP) and regenerative thermal oxidation (RTO). Its core principles are as follows: plasma pretreatment: using active free radicals generated by high-voltage discharge to crack large molecular VOCs into small molecular intermediates, reducing the energy consumption of subsequent oxidation; regenerative thermal oxidation deep treatment: the intermediate products enter the RTO system and are completely decomposed into CO2 and H2O at high temperature. The regenerative thermal body recovers heat to improve energy efficiency. This technology is suitable for the efficient purification of high-concentration, complex component VOCs, combining the advantages of low-temperature reaction (plasma) and thorough mineralization (RTO).
[0003] In the treatment process of the composite industrial organic waste gas treatment equipment of plasma and thermal storage oxidation, it is usually necessary to go through the process of waste gas collection, pretreatment (filtering dust and oil mist), plasma reactor, thermal storage oxidation furnace and other processes before exhaust emission. In the pretreatment stage, the waste gas usually needs to be filtered. At present, due to the adsorption capacity of activated carbon itself, it has a good effect on waste gas treatment. Therefore, multiple activated carbon filter elements are usually designed in sequence in the pretreatment filter assembly, and then discharged into the subsequent process after filtration. After processing, they are released to reduce the atmospheric pollution caused by the waste gas to the environment. However, most activated carbon filter elements are usually frame structures and overall designs. When the activated carbon filter element is saturated with the waste gas adsorption, the overall activated carbon filter element needs to be replaced and replaced with a new activated carbon filter element for use. This seriously causes waste of activated carbon filter elements. Not only that, the utilization effect of activated carbon in this way is also low. How to invent a composite industrial organic waste gas treatment device based on plasma and thermal storage oxidation to solve these problems has become a problem that needs to be solved urgently by those skilled in the art.

[0019] The multi-level pore structure of the high-efficiency activated carbon in the adsorption assembly allows for targeted adsorption of organic matter of varying molecular sizes. Combined with the uniform upward flow guided by the guide assembly and the agitation of the activated carbon by the side panels, the contact area between the activated carbon and the exhaust gas is increased, improving adsorption efficiency and utilization. The increased weight of the activated carbon after adsorbing organic waste gas compresses the telescopic spring, causing the support rod to slide. A displacement sensor triggers the electromagnetic coil and fan to start, enabling automatic identification of activated carbon adsorption saturation, eliminating manual inspection delays. The electromagnetic coil, in conjunction with the iron side panels, stirs the activated carbon particles through a magnetic field, while the fan creates a directional airflow to assist thermal desorption. The synergistic effect of mechanical agitation and airflow scouring disrupts the adsorption equilibrium, making it suitable for deep desorption of high-boiling-point organic matter. Furthermore, the spiral blades lift the activated carbon particles to the scattering plate for redistribution. During the scattering process, the particles rub against each other, shedding organic matter adhering to the surface and exposing new adsorption sites for temporary activation. Combined with the desorption effect, this creates a "stirring-scattering-desorption" cycle, extending the life of the activated carbon, thereby reducing replacement frequency and waste.

DETAILED DESCRIPTION
[0031] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.
[0032] Example 1
[0033] Reference Figures 1-9 The composite industrial organic waste gas treatment device based on plasma and thermal storage oxidation includes a treatment tube 1, a plasma device 2 and a thermal storage oxidation furnace 3. The thermal storage oxidation furnace 3 is connected to an exhaust pipe 4. A filter plate 6 and a rotating shaft 9 are provided inside the treatment tube 1. The treatment tube 1 is connected to a motor 8 and further includes:
[0034] Adsorption component 5, which is located inside the treatment cylinder 1, and absorbs substances in the organic waste gas through high-efficiency activated carbon;
[0035] The flow guide component 7 is located inside the treatment cylinder 1 and is used to guide the upward flow of the air.
[0036] Furthermore; the treatment cylinder 1 is located on one side of the plasma equipment 2, the thermal storage oxidation furnace 3 is located on the side of the plasma equipment 2 away from the treatment cylinder 1, the bottom wall of the treatment cylinder 1 is fixedly connected to the motor 8, one end of the motor 8 passes through the bottom wall of the treatment cylinder 1 and is fixedly connected to one end of the rotating shaft 9, the inner wall of the treatment cylinder 1 and the filter plate 6 are detachably connected, and the side wall of the filter plate 6 and the outer wall of the rotating shaft 9 are rotatably connected.
[0037] The overall processing process of the equipment: the treatment tube 1 and the plasma equipment 2 are connected by a pipeline, and the plasma equipment 2 and the thermal storage oxidizer 3, as well as the thermal storage oxidizer 3 and the exhaust pipe 4 are all connected by pipelines. The plasma equipment 2 and the thermal storage oxidizer 3 belong to the existing technology, so they are not described in detail. When treating the organic waste gas from the factory, the air inlet pipe on one side of the treatment tube 1 can be connected to the corresponding external equipment to discharge the waste gas into the interior of the treatment tube 1.
[0038] Reference Figure 2 、 Figure 3 and Figure 7 The hopper 76 is fixed on the top of the hopper 76, and the hopper 76 is fixed on the top of the hopper 76. The hopper 76 is fixed on the top of the hopper 76, and the hopper 76 is fixed on the top of the hopper 76.
[0039] The guide component 7 guides the gas: after the exhaust gas enters the treatment cylinder 1, the filter plate 6 can initially intercept large particles of dust, and then cool it down through the condensation hood 71, so that high-boiling point substances such as oil mist are condensed into liquid and adhere to the hood wall, reducing the risk of clogging of the subsequent high-efficiency activated carbon inside the carrier cylinder 52. At the same time, the motor 8 can be started by an external controller, so that the motor 8 serves as a power source to provide power for the rotation of the rotating shaft 9, and the electrical components in the equipment are all powered by an external power supply. During the rotation of the rotating shaft 9, the guide blades 76 in the guide cylinder 72 can rotate synchronously with the rotating shaft 9 to generate an upward airflow traction force. At the same time, the airflow contact area is expanded by the expansion hood 73, so that the exhaust gas rises evenly to the adsorption component 5. The mutual cooperation between the condensation hood 71 and the guide blades 76 can achieve the effect of "cooling and oil removal + airflow homogenization", creating conditions for high-efficiency activated carbon adsorption, and avoiding the problem of oil mist covering the activated carbon pores and causing the adsorption efficiency to decrease;
[0040] In addition, the support rod 74 is in an "I"-shaped structure, one end of which is clamped and fixed to the bottom of the supporting tube 52, and the other end is embedded in the slide groove of the expansion cover 73, which can slide up and down along the axial direction. The telescopic spring 75 mounted on the outer wall of the support rod 74 is made of stainless steel, and its two ends respectively abut the end surface of the expansion cover 73 and the flange of the support rod 74 to form an elastic supporting structure. When the supporting tube 52 moves downward due to the weight increase of the activated carbon adsorption, the telescopic spring 75 is compressed and generates a reverse elastic force, which buffers the descending speed of the supporting tube 52 and avoids the accumulation of activated carbon particles inside due to gravity impact. When the activated carbon is desorbed and loses weight, the spring force pushes the support rod 74 upward, pushes the supporting cylinder 52 to reset, and disconnects the electromagnetic coil 53 and the fan 563 from being energized. This design limits the movement range of the supporting cylinder 52 by the elastic deformation of the spring, and at the same time utilizes the I-shaped cross-section of the support rod 74 and the slide groove of the expansion cover 73 to prevent the supporting cylinder 52 from radially offsetting during movement, ensuring its stable sliding in the vertical direction, thereby maintaining the relative position accuracy of the adsorption component 5 and the guide component 7, and avoiding airflow short-circuiting or equipment wear due to component shaking.
[0041] Example 2
[0042] Reference Figure 2-Figure 9, further; the adsorption assembly 5 includes a cover plate 51 and a carrying cylinder 52, one end of the carrying cylinder 52 is fixedly engaged with one end of the support rod 74, and the other end of the carrying cylinder 52 is detachably connected to the cover plate 51, an electromagnetic coil 53 is provided inside the carrying cylinder 52, and a baffle 54 is fixedly connected to the side wall of the carrying cylinder 52, the baffle 54 is annular, and the outer wall of the baffle 54 is slidably connected to the inner wall of the expansion cover 73; one side of the cover plate 51 is fixedly connected to a vertical plate 512, and the end of the vertical plate 512 away from the cover plate 51 is fixedly connected to the vertical cylinder 513, and the outer wall of the vertical cylinder 513 is fixedly connected There is a scattering plate 511, which is flush with the end connected to the vertical tube 513 and the vertical plate 512; the outer wall of the movable cover 55 located on the inner side of the supporting tube 52 is fixedly connected with a plurality of circumferential array distributed toggle rods 551, and the side wall of the toggle rod 551 is fixedly connected with a side plate 552. A ventilation groove 5511 is provided inside the toggle rod 551, and a cavity 5522 is provided inside the side plate 552. The inner wall of the cavity 5522 is provided with a plurality of array-distributed exhaust holes 5521, and the ventilation groove 5511 is respectively connected with the inner wall of the movable cover 55 and the cavity 5522.
[0043] Adsorption treatment of organic waste gas by high-efficiency activated carbon: During the treatment of organic waste gas, the interior of the carrier cylinder 52 is filled with high-efficiency activated carbon particles. Its multi-level pore structure can specifically adsorb organic matter of different molecular sizes. When the rotating shaft 9 is driven to rotate by the motor 8, the fixed cylinder 56 forms a sliding fit with the limiting groove 555 of the movable cover 55 through the limiting strip 561, driving the movable cover 55 to rotate synchronously. The toggle rod 551 on the outside of the movable cover 55 generates a circumferential traction force as it rotates, causing the side plate 552 (made of iron metal) to continuously stir the activated carbon particles. The side plate 552 and the upper end surface of the toggle rod 551 are designed at a specific inclination angle. When rotating, they can not only break the activated carbon accumulation state, but also gather the particles toward the rotating column 554, making it easier for the spiral blade 553 to lift and scatter them;
[0044] The sidewalls of the support tube 52 are made of porous ceramic gas distribution plates. Their evenly distributed micropores ensure that the exhaust gas penetrates the activated carbon bed at a stable flow rate. Together with the annular channel formed by the baffle 54 and the expansion cover 73, this prevents the exhaust gas from bypassing and diffusing, forcing the airflow to pass radially through the gaps between the activated carbon particles, thereby improving mass transfer efficiency.
[0045] The outer side of the iron side plate 552 is sprayed with a thermal insulation ceramic coating to prevent local overheating caused by eddy current heat during operation of the electromagnetic coil 53 and to resist corrosion from acidic exhaust gas. During the stirring process, the side plate 552 breaks up the activated carbon agglomerates through physical shearing, re-exposing previously buried adsorption sites and promoting airflow penetration between particles to avoid adsorption saturation in a single area.
[0046] After the particles are lifted to the vertical cylinder 513 by the spiral blades 553, they are evenly scattered through the scattering plate 511. During the falling process, they are fully in contact with the rising airflow, which can further increase the adsorption reaction time. This design breaks the mass transfer bottleneck of traditional fixed bed adsorption through the synergistic effect of mechanical agitation and airflow distribution, allowing the activated carbon particles to maintain efficient utilization of adsorption sites during dynamic motion. At the same time, it creates loose and porous structural conditions for the subsequent desorption and regeneration process, ensuring that the organic waste gas meets the air intake requirements of the subsequent plasma and thermal storage oxidation processes after adsorption treatment.
[0047] Dynamic adsorption and triggering mechanism of adsorption assembly 5: The high-efficiency activated carbon particles in the carrier cylinder 52 adsorb organic waste gas. As the adsorption amount increases, some substances in the waste gas will adhere to the surface or inside of the activated carbon. In the process of industrial waste gas discharge, there is more waste gas, so the activated carbon adsorbs more substances. Therefore, as the adsorption time increases, the weight of the entire carrier cylinder 52 begins to increase, which will compress the telescopic spring 75 at the expansion cover 73, causing the support rod 74 to slide downward. The displacement sensor 556 on the inner wall of the movable cover 55 can monitor the displacement of the movable cover 55 (that is, the weight of the carrier cylinder 52). The displacement sensor 556 is electrically connected to the electromagnetic coil 53 and the fan 563, respectively. When the displacement sensor 556 detects movement within a certain range, it triggers the electromagnetic coil 53 and the fan 563 in the fixed cylinder 56 to start. The weight-triggered design can realize automatic identification of activated carbon adsorption saturation, avoiding manual inspection delays; the electromagnetic coil 53 cooperates with the iron side plate 552 to stir the activated carbon particles through the magnetic field. At the same time, the fan 563 blows air out through the ventilation slot 5511 and the exhaust hole 5521, enhancing the airflow penetration between the particles and improving the desorption efficiency.
[0048] Furthermore, the adsorption assembly 5 also includes a movable cover 55 and a fixed cylinder 56, one end of the fixed cylinder 56 is fixedly connected to the end of the rotating shaft 9 away from the motor 8, the inner wall of the fixed cylinder 56 is fixedly connected to a fixed frame 562, the inner wall of the fixed cylinder 56 is provided with a limit strip 561, the fixed frame 562 is located below the limit strip 561, and the side wall of the fixed frame 562 is provided with a fan 563; the movable cover 55 is arranged in a "T" shape, one end of the movable cover 55 is slidably connected to the inner wall of the fixed cylinder 56, and one end of the movable cover 55 A limiting groove 555 is provided to cooperate with the limiting bar 561, and the outer wall of the movable cover 55 is rotatably connected to the side wall of the supporting cylinder 52; the end of the movable cover 55 away from the fixed cylinder 56 is fixedly connected to the rotating column 554, and the outer wall of the rotating column 554 is fixedly connected to the spiral blade 553, and the end of the spiral blade 553 away from the rotating column 554 is slidably connected to the inner wall of the vertical cylinder 513, the length of the spiral blade 553 is greater than the depth of the vertical cylinder 513, and the inner wall of the movable cover 55 is provided with a displacement sensor 556.
[0049] Desorption process of electromagnetic coil 53 and fan 563: after electromagnetic coil 53 is energized, it generates an alternating magnetic field, causing the iron side plate 552 to generate heat, and cooperates with the movable cover 55 to drive the toggle rod 551 to stir the activated carbon particles, thereby destroying the organic adhesion layer formed between the particles due to adsorption saturation. At this time, the fan 563 sends air into the interior of the movable cover 55, and flows through the ventilation groove 5511 and the internal cavity 5522 of the side plate 552, and finally blows it out evenly from the exhaust hole 5521 to form a directional airflow, which assists thermal desorption and releases the organic matter adsorbed on the surface of the activated carbon. Mechanical stirring and air flow flushing work together to break the adsorption balance and improve the desorption efficiency. The magnetic field effect of the electromagnetic coil 53 can assist in heating the activated carbon, and combined with the airflow of the fan 563, it can form a "magnetic thermal-pneumatic" composite desorption, which is suitable for deep desorption of high-boiling point organic matter. The main working principle is the side plate 552 cuts the magnetic lines of force in the alternating magnetic field (generated by the electromagnetic coil 53), generating eddy currents inside (with a frequency consistent with the coil current). According to Joule's law, the eddy current heat causes the temperature of the side plate 552 to rise, and acts on the surrounding activated carbon particles through heat conduction. When the side plate 552 is heated to a certain temperature, combined with the magnetic field thermal effect of the electromagnetic coil 53, the saturated activated carbon can be heated to a suitable temperature, causing the adsorbed organic matter to be thermally decomposed or volatilized and desorbed. Part of the activated carbon surface structure is regenerated through carbonization. At the same time, combined with the action of the magnetic field, the activated carbon particles near the side plate 552 generate micro-vibrations due to magnetostriction, which can promote the diffusion and desorption of residual organic matter (such as toluene) in the pores, thereby improving the desorption efficiency. After the electromagnetic coil 53 and the fan 563 are started, the activated carbon is regenerated through magnetic field stirring and airflow flushing. The desorbed high-concentration exhaust gas enters the plasma equipment 2 and the thermal storage oxidation furnace 3 for destruction.
[0050] The activated carbon activation mechanism of the spiral blade 553 and the vertical cylinder 513: When the movable cover 55 rotates with the rotating shaft 9, the rotating column 554 drives the spiral blade 553 to stir in the vertical cylinder 513. During normal operation, the high-efficiency activated carbon particles can be lifted from the bottom of the carrier cylinder 52 to the scattering plate 511, so that they are scattered and redistributed inside the carrier cylinder 52. During the scattering process, the high-efficiency activated carbon particles will be in the air for a period of time. At this time, the particles will no longer accumulate at the bottom of the carrier cylinder 52, which can increase the contact area between the particles and the exhaust gas, thereby improving its adsorption effect. In addition, when the electromagnetic coil 53 and the fan 5 When 63 is working, the spiral blade 553 also lifts the adsorption-saturated activated carbon particles from the bottom of the supporting tube 52 to the scattering plate 511, so that they are scattered and redistributed. However, in the scattering process, the activated carbon particles will also rub against each other, and some organic matter adhering to the surface will fall off, exposing new adsorption sites at the same time to achieve temporary activation. The mechanical dispersion of the spiral blade 553 and the particle reorganization of the scattering plate 511 cooperate to increase the contact area between the activated carbon and the exhaust gas, slow down the adsorption saturation speed, and combine with the desorption effect of the electromagnetic coil 53 to form a "stirring-scattering-desorption" cycle, thereby extending the service life of the activated carbon.
[0051] It should be noted that the specific models and specifications of electrical components such as motors and fans need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
