Description

Technical Field

[0001] The invention relates to the technical field of spray-washing separation equipment, and in particular to malodorous waste gas treatment equipment with an ultrasonic atomization gas-liquid mixing structure. Background Art

[0002] In the treatment of malodorous waste gas, deodorizing liquid is generally used as atomized liquid to disperse it into a large number of tiny droplets, creating good conditions for sufficient mixing and reaction with malodorous waste gas. Ultrasonic atomizer uses high-frequency oscillation to make the liquid produce high-frequency vibration under the action of ultrasonic wave, destroying the surface tension of the liquid and breaking the liquid into tiny droplets. The solubility difference of certain components in malodorous gas in liquid absorbent is used to dissolve the easily soluble malodorous gas components in the liquid, thereby realizing the transfer from gas phase to liquid phase and achieving the purpose of separation and removal. The active ingredients in the liquid absorbent react chemically with the malodorous gas to convert the malodorous gas into harmless or easy-to-handle substances. The reaction is usually irreversible and can remove the malodorous gas more thoroughly.

[0003] During the waste gas treatment process, the packing is in a relatively static state, the waste gas flows from bottom to top, and the spray liquid is sprayed from top to bottom. When the waste gas passes through the packing layer, the pollutants in it are fully in contact with the liquid film and are removed through physical absorption, chemical reaction and other processes. However, the malodorous waste gas may carry some solid particles, such as dust, particulate matter and other impurities. As the treatment process continues, these impurities will continue to accumulate on the surface and gaps of the packing, resulting in blockage. The resistance of the packing in this area increases due to the blockage. In order to seek a channel with low resistance, the gas will bypass these areas and form a gas short circuit, which makes it impossible for the waste gas to fully contact and react with the liquid on the surface of the packing, and the malodorous substances are difficult to be effectively removed. At the same time, when treating malodorous waste gas containing organic matter, microorganisms will use the organic matter in the waste gas to grow and form a thick biofilm on the surface of the packing. Microorganisms and their metabolites, dead bacteria, etc. will interact with impurities in the waste gas and components in the spray liquid to form biofouling. Biofouling will not only block the pores of the packing, but also change the surface properties of the packing, affecting gas-liquid mass transfer. At the same time, biofouling may produce odors and have a negative impact on the treatment effect. Summary of the invention

When the main shaft 1 and the main shaft 2 rotate synchronously in opposite directions, the filling part carrying the filling rotates synchronously with the main shaft 2, so that the filling moves in the filling part. The main shaft 1 drives the atomizing part to rotate, and the atomizing part in the rotating state uniformly sprays the filling in the active state. The atomizing part in the primary spraying area is fixed on the inner wall of the limiting ring, and the middle part of the filling part is connected to the main shaft 2, and the atomizing part in the fixed state sprays the filling in the active state. Wherein, the inner wall of the limit ring is provided with a rotating block for adjusting the vertical position of the filler part.

[0007] Furthermore, the atomization part includes a fixed plate fixedly connected to a bottom end of the main shaft, spray rods are evenly arranged on the side of the fixed plate, and a water irrigation pipe is sealed and slidably provided at the other end of the spray rod.

[0013] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: The present invention is provided with a packing part capable of rotating. The packing part will generate fluctuations during the rotation. The rotation of the screen causes the surface of the packing to change continuously. The rotation and fluctuation of the packing make it difficult for impurities attached to the surface to stay and accumulate. During the rotation process, the centrifugal force will throw out some impurities. The fluctuation causes the surface of the packing to change continuously, reducing the chance of impurities attaching. The present invention is provided with a driving part, which drives the filling part and the atomizing part to rotate in the opposite direction. The rising gas and the spray are further mixed in the process of exhaust gas treatment. The spray liquid is ejected during the rotation process to disturb the surrounding gas. This disturbance makes the gas flow more turbulent, increases the contact opportunity and collision frequency between the gas and the spray liquid droplets, and strengthens the mass transfer process between gas and liquid. During the rotation process, the spray liquid droplets can be more evenly distributed in the treatment space under the combined action of centrifugal force and airflow, avoiding excessive concentration or sparseness of droplets in local areas, making the gas-liquid mixing more uniform, and further improving the exhaust gas treatment effect.

[0014] The present invention divides the spray area in the spray tower into an enhanced spray area and an initial spray area from top to bottom. The atomizing part in the primary spray area is fixed on the inner wall of the limiting ring, and the middle part of the packing part is connected to the second main shaft. The atomizing part in the fixed state sprays the packing in the active state to complete the primary waste gas treatment. The first main shaft and the second main shaft in the enhanced spray area rotate synchronously in the opposite direction, and the packing part carrying the packing rotates synchronously with the second main shaft, so that the packing moves in the packing part. The first main shaft drives the atomizing part to rotate, and the atomizing part in the rotating state evenly sprays the packing in the active state. In a dynamic environment, the gas and liquid sides can exchange substances more efficiently, which accelerates the transfer speed of pollutants in the waste gas to the liquid phase.

[0015] The present invention is provided with a positioning piece, through which the filling part and the atomization part are connected. When the filling fluctuates, the positioning piece as a connecting structure can evenly disperse the impact force generated by the shaking and collision of the filling, thereby avoiding local deformation of the filling part during movement and affecting the stability of the overall structure.

[0016] The present invention is provided with an atomizing part. When the spray rod rotates to the water reservoir position, the water reservoir pours a certain amount of liquid into the spray rod. As the fixed plate rotates, liquid can be continuously added to the spray rod. There is no need for the spray rod to carry a large amount of liquid during the rotating spraying process, which avoids interference with the spraying process due to changes in liquid weight. At the same time, only a certain amount of liquid is stored in the spray rod, which avoids crystallization and clogging of the pipeline due to long-term storage of liquid, thereby improving the service life of the device.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution 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 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 creative work are within the scope of protection of the present invention.

[0021] The present invention will be further described below in conjunction with the embodiments. Example

[0022] See also Figure 1-Figure 8 The present invention provides a technical solution for treating malodorous waste gas with an ultrasonic atomization gas-liquid mixing structure: the device comprises a spray tower 1, and the interior of the spray tower 1 is sequentially arranged from top to bottom as a demisting layer, a spraying area and a circulating water area, such as Figure 2 As shown, the spray area is divided into an enhanced spray area and a primary spray area. Both spray areas are composed of a packing part 3, an atomizing part 4 and a positioning part 5. The atomizing part 4 is used to atomize the liquid, the packing part 3 is used to carry the packing, and the positioning part 5 is located between the packing part 3 and the atomizing part 4. A driving part 6 is provided at the top of the spray tower 1, which is located directly above the demister. An outlet for the treated gas output is provided around the driving part 6 at the top of the spray tower 1. The packing part 3 is located on the inner wall of the spray tower 1, and the outer wall of the packing part 3 is embedded in the limiting ring 2. The packing part 3 is used to carry the packing of the mixed gas and liquid. The upper surface of the packing part 3 is provided with a positioning part 5, and the upper surface of the positioning part 5 is provided with the atomizing part 4.

[0023] The packing in the prior art is in a relatively static state. When the waste gas passes through the packing layer, the pollutants therein are in full contact with the liquid film. The malodorous waste gas may carry some solid particles, such as dust, particulate matter and other impurities. As the treatment process continues, these impurities will continue to accumulate on the surface and gaps of the packing, causing blockage. The resistance of the packing in this area increases due to the blockage. Therefore, the packing part 3 provided in the present invention is set to be movable.

[0024] refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 The driving part 6 includes a protection frame 67 fixed to the middle of the top of the spray tower 1, a motor 61 is fixedly connected to the middle of the protection frame 67, a gear 1 62 is fixedly connected to the output end of the motor 61, the middle of the gear 1 62 is fixedly connected to the top of the main shaft 2 66, the side of the gear 1 62 is meshed with the gear 2 63, the lower surface of the gear 2 63 is meshed with the gear 3 64, the bottom end of the gear 3 64 is fixedly connected to the middle of the top of the main shaft 1 65, the main shaft 2 66 is embedded in the main shaft 1 65, and the primary spray The atomizing part 4 in the shower area is fixed on the inner wall of the limiting ring 2, and the middle part of the filling part 3 is connected to the main shaft 66. The atomizing part 4 in the fixed state sprays the filling in the movable state. The filling part 3 includes a blocking block 32 embedded in the inner wall of the limiting groove 21 and slidably connected thereto. The other end of the blocking block 32 is fixedly connected to a leakage net 31. The center position of the leakage net 31 is ball-jointed to the main shaft 66. The upper surface of the leakage net 31 is symmetrically fixed with wave plates 33, and the edge position of the upper surface of the leakage net 31 is fixedly connected with a leakage ring 34.

[0025] The motor 61 starts and drives the gear 1 62 to rotate. The rotation of the gear 1 62 drives the main shaft 2 66 to rotate. At the same time, the rotation of the gear 1 62 is transmitted to the gear 3 64 through the gear 2 63 meshing therewith. The gear 3 64 rotates in the opposite direction to the gear 1 62. The gear 3 64 drives the main shaft 1 65 to rotate. The rotation of the main shaft 1 65 drives the atomization part 4 of the enhanced spraying area to move. The rotation of the main shaft 2 66 drives the packing part 3 to rotate. The overall rotation of the packing part 3 causes the packing carried inside to change its position inside the packing part 3 due to the action of centrifugal force and friction force. The surface of the wave plate 33 adopts an arc design with one end larger than the other end. When the wave plate 33 rotates with the leakage screen 31, the wave plate 33 will push the packing, so that the packing has differences in speed and direction at different positions. This irregular movement of the packing further avoids blockage.

[0026] Rotation accelerates the renewal of the liquid film on the packing surface and shortens the residence time of the liquid on the packing surface, which is beneficial to improving the mass transfer rate between gas and liquid. At the same time, the tumbling and collision of the packing make the diffusion path of gas and liquid inside the packing more complex and tortuous, increasing the contact time and contact area between gas and liquid, and further enhancing the gas-liquid mass transfer effect.

[0027] The rotation of the screen 31 drives the movement of the packing, making the flow of gas and liquid in the packing layer more turbulent and sufficient, avoiding local short circuit or channeling of gas and liquid in the packing layer, thereby promoting uniform contact between gas and liquid and improving the stability of mass transfer efficiency.

[0028] During the rotation of the packing, the impurities on its surface are more easily thrown off the packing surface due to the centrifugal force. At the same time, the tumbling and collision of the packing will make the impurities already attached to the packing surface fall off more easily, thereby reducing the adhesion and accumulation of impurities on the packing and reducing the risk of blockage.

[0029] Due to the movement of the filler, its position in the filter screen 31 is constantly changing, so that the gaps between the fillers are not easily blocked by impurities or sediments, and a good gap structure can be maintained to ensure smooth flow of gas and liquid, thereby extending the service life of the filler and the stable operation time of the equipment.

[0030] The driving part 6 in the enhanced spraying area includes a main shaft 1 65 connected to the upper surface of the atomizing part 4 and a main shaft 2 66 connected to the upper surface of the packing part 3. When the main shaft 1 65 and the main shaft 2 66 rotate synchronously in opposite directions, the packing part 3 carrying the packing rotates synchronously with the main shaft 2 66, so that the packing moves in the packing part 3, and the main shaft 1 65 drives the atomizing part 4 to rotate. The atomizing part 4 in the rotating state evenly sprays the packing in the active state. A limiting groove 21 is provided on the inner wall of the limiting ring 2, and a limiting groove 21 is provided at the bottom end of the inner wall of the limiting groove 21. A fixed block 22 is fixedly connected to the inner wall of the limiting groove 21. A knob spring is sleeved on the outer surface of the fixed block 22. The knob spring is connected to the middle part of one end of the rotating block 23. When the rotating block 23 rotates with the fixed block 22 as the center, it needs to overcome the elastic force of the knob spring. The inner wall size of the limiting groove 21 is slightly larger than the diameter size of the blocking block 32, and there is a movable space for the blocking block 32 on the inner wall of the limiting groove 21.

[0031] refer to Figure 8 The second main shaft 66 includes a positioning shaft 661 whose top is fixedly connected to the bottom end of the gear 1 62, a ball shaft 662 is fixedly connected to the side of the bottom end of the positioning shaft 661, a positioning block 663 connected to the center position of the leakage net 31 with a ball joint is fixedly connected to the bottom end of the ball shaft 662, another positioning shaft 661 is fixedly connected to the bottom end of the positioning block 663, one end of the other positioning shaft 661 passes through the atomization part 4 of the primary spraying area, another positioning shaft 661 is fixedly connected to the bottom end of the other positioning shaft 661 with another positioning block 663 connected to the center ball joint of the leakage net 31 in the primary spraying area, a positioning groove is opened in the middle position of the leakage net 31, the bottom end of the positioning groove adopts a spherical design, and the bottom end size of the spherical part is slightly larger than the size of the positioning block 663, and an arc groove for engaging and limiting the ball shaft 662 is opened on the side of the inner wall of the positioning groove.

[0032] The rotation of the positioning shaft 661 drives the ball shaft 662 to rotate, the rotation of the ball shaft 662 drives the leakage net 31 to rotate, the rotation of the leakage net 31 drives the blocking block 32 to rotate, the blocking block 32 rotates and contacts with the evenly arranged raised parts of the rotating block 23, the blocking block 32 contacts with the rotating block 23 and gradually overcomes the elastic force of the rotating block 23 before passing through the limiting groove 21 area, due to the interference of this force during the rotation process, the leakage net 31 will fluctuate to a certain extent when the rotating block 23 and the blocking block 32 act together.

[0033] The filler part 3 also moves in the vertical position during the rotation process. In addition to rotating with the collet 31, the filler also performs irregular up and down and left and right movements in the collet 31 under the action of the wave, forming a complex three-dimensional motion trajectory. This complex movement causes the relative positions of the fillers to change continuously, increasing the contact opportunities and contact areas between the fillers and the gas and liquid. The wave will intensify the collision and friction between the fillers and between the fillers and the collet 31. Under the joint action of rotation and wave, the collision frequency and intensity between the filler particles are increased, which helps to remove dirt and impurities on the surface of the filler and prevent the filler from being blocked. At the same time, it can also continuously update the surface of the filler and improve the gas-liquid mass transfer efficiency. During the rotation process, the centrifugal force will throw out some impurities, and the wave will cause the surface of the filler to change continuously, reducing the chance of impurity adhesion. When treating dust-containing smelly waste gas, impurities such as dust are not easy to accumulate on the filler, reducing the risk of blockage and extending the operation cycle of the equipment.

[0034] The synergistic effect of rotation and fluctuation makes the distribution of the filler in the mesh 31 more uniform. The centrifugal force generated by the rotation will make the filler tend to move to the periphery, while the fluctuation will disrupt this single centrifugal distribution trend, making the filler more evenly distributed at different positions and heights of the mesh 31, avoiding excessive accumulation or sparseness of the filler in local areas, thereby improving the overall mass transfer efficiency of the filler layer. During the rotation and fluctuation of the mesh 31, the distribution of the filler is not fixed, but will be dynamically adjusted according to changes in conditions such as gas-liquid flow rate and pressure. When the gas-liquid flow rate is large or the pressure is high, the filler may be arranged more closely under the action of fluctuation to adapt to the larger load. When the gas-liquid flow rate is small or the pressure is low, the packing may be relatively loose to ensure that the gas and liquid can fully contact and transfer mass. The complex movement and uniform distribution of the packing make the gas-liquid mass transfer process in the packing layer more sufficient and efficient. When the gas and liquid pass through the packing layer, they will fully contact with the constantly moving and updated packing surface, increasing the diffusion and reaction opportunities between the gas and liquid, thereby improving the mass transfer efficiency and treatment effect. The rotation and fluctuation of the screen 31 will transfer mechanical energy to the packing, so that the packing obtains kinetic energy and moves. This energy transfer not only promotes the movement and mass transfer process of the packing, but also changes the flow direction and velocity distribution of the gas and liquid, further optimizing the gas-liquid mass transfer effect.

[0035] refer to Figure 2 and Figure 4 The atomizing part 4 includes a fixing plate 41 fixedly connected to the bottom end of the main shaft 65, spray rods 42 are evenly arranged on the side of the fixing plate 41, and a water filling pipe 43 is sealed and slidably provided at the other end of the spray rod 42. A water reservoir 44 for filling liquid is arranged on the inner wall of the water filling pipe 43, and a slide groove 45 is opened at the bottom of the water filling pipe 43.

[0036] The rotation of the main shaft 65 drives the fixed plate 41 to rotate, and the rotation of the fixed plate 41 drives the spray rod 42 to rotate. When the spray rod 42 rotates to the position of the water reservoir 44, the water reservoir 44 pours a certain amount of liquid into the spray rod 42. As the fixed plate 41 rotates, liquid can be added to the spray rod 42 continuously. There is no need for the spray rod 42 to carry a large amount of liquid during the rotation and spraying process, which avoids interference with the spraying process due to changes in liquid weight. At the same time, only a certain amount of liquid is stored in the spray rod 42, which avoids crystallization and clogging of the pipeline due to long-term storage of liquid, thereby increasing the service life of the device.

[0037] During the rotation of the atomizing section 4, the spray droplets can be more evenly distributed in the treatment space under the combined action of centrifugal force and airflow, avoiding excessive concentration or sparseness of droplets in local areas. The liquid sprayed by the rotating atomizing section 4 in the Tsinghua spray area is more widely sprinkled on the surface of the filler under the action of centrifugal force, forming a thinner and larger liquid film. At the same time, the filler fluctuates with the filler section 3 to cause irregular undulations and wrinkles in the liquid film, further increasing the gas-liquid contact area. The larger contact area increases the contact opportunities between organic molecules and the absorption liquid, thereby improving the absorption efficiency. The rotation and fluctuation make the relative movement of gas and liquid more complex and violent. Under the action of the rotation and fluctuation of the filler, the gas constantly changes its flow direction and collides and contacts with the liquid more frequently. In a dynamic environment, the gas and liquid can exchange substances more efficiently, accelerating the transfer speed of pollutants in the exhaust gas to the liquid phase.

[0038] Traditional static packing is prone to uneven distribution of gas and liquid, with more liquid near the tower wall and less liquid in the center area. However, the packing that rotates and fluctuates with the filter 31 can make the liquid more evenly distributed on the packing surface and flow in all directions under the combined effect of rotation and fluctuation. At the same time, the gas will be more evenly dispersed in the liquid due to the dynamic changes of the packing, avoiding the phenomenon of gas short circuit, ensuring that the entire packing area can fully participate in the gas-liquid mass transfer process. This dynamic packing movement mode has better adaptability to the fluctuation of the waste gas and absorption liquid flow. When the flow increases, the rotation and fluctuation can promote the gas and liquid to mix and disperse more quickly, avoiding insufficient gas-liquid contact due to excessive flow; when the flow decreases, it can also maintain a certain gas-liquid mixing intensity through dynamic action to ensure the stability of the treatment effect.

[0039] The above structure divides the spray area into two areas, and sprays at different intensities alternately to make the absorption liquid more evenly distributed, avoid local corrosion, and maintain the structural integrity and stability of the equipment. The design of the packing part 3 and the atomizing part 4 in the spray area achieves the advantages of strengthening gas-liquid mass transfer, improving gas-liquid distribution and preventing blockage, which significantly improves the waste gas treatment efficiency. Under the same treatment time and equipment volume, it can more effectively remove pollutants in the waste gas, making it easier for the exhaust gas to meet environmental protection standards. In actual use, this dynamic packing operation mode can flexibly adapt to the waste gas treatment needs of different components, concentrations and flow rates by adjusting the rotation speed and fluctuation amplitude. For waste gas with higher concentration, the rotation speed and fluctuation amplitude can be appropriately increased to strengthen the mass transfer process; for waste gas with simple components and lower concentration, the operation intensity can be reduced to save energy.

[0040] The filler consumes a certain amount of energy during the rotation and fluctuation process, and this energy mainly comes from the rotational power of the screen 31. Therefore, the present invention is provided with a positioning member 5 to ensure the economical operation and energy saving of the equipment.

[0041] refer to Figure 2 and Figure 7 The positioning member 5 includes a slider 51 slidably connected to the slide groove 45, a connecting rod 52 is fixedly connected to the bottom end of the slider 51, and a limiting ball 53 is fixedly connected to the bottom end of the connecting rod 52; the leakage net 31 rotates and fluctuates while driving the leakage ring 34 to move synchronously, and the limiting ball 53 can change the angle between the two with the slight change of the vertical position of the fixed groove 341, but because the slider 51 with the top embedded in the inner wall of the slide groove 45, the positioning member 5 will not be vertically displaced, and the slider 51 and the slide groove 45 move relative to each other in the spraying area, and the slider 51 with the side set as an inclined surface can also remove a small amount of impurities attached to the inner wall of the slide groove 45.

[0042] The packing part 3 and the atomizing part 4 are connected by the positioning member 5. When the blocking block 32 contacts the rotating block 23, under the influence of collision resistance and other multiple factors, the leakage net 31 fluctuates vertically. The fluctuation range near the center of the circle is smaller than the outer wall. Therefore, the positioning member 5 set at the leakage ring 34 is used to share the greater gravity of the leakage net 31 during fluctuation to ensure stability. When the packing fluctuates, the positioning member 5 as a connecting structure can evenly disperse the impact force generated by the shaking and collision of the packing, so as to avoid local deformation of the packing part 3 during movement, which affects the stability of the overall structure. When the packing part 3 rotates, it will drive the positioning member 5 to rotate as a whole. The outer wall of the connecting rod 52 is provided with a cleaning strip. The relative movement of the cleaning strip and the inner wall of the equipment will produce a similar "wiping" effect, which can remove a small amount of impurities that have been attached to the surface of the packing and achieve self-cleaning.
