Description

Technical Field

[0001] This invention relates to the field of acid gas treatment equipment technology, and in particular to an intelligent wet treatment equipment for acid gases. Background Technology

[0002] Acidic gases are major gaseous pollutants in industrial production fields such as chemical, metallurgical, power, electronic manufacturing and energy chemical industries. If these gases are emitted directly without effective treatment, they will not only pollute the atmospheric environment and cause environmental problems such as acid rain and smog, but also pose a direct threat to human health. Therefore, the efficient purification and treatment of acidic gases is a key technical link in the prevention and control of air pollution and the achievement of industrial environmental protection emission standards.

[0003] Among various technologies for treating acidic gases, wet scrubbing has become the mainstream process for the harmless treatment of acidic gases due to its mature technology, sufficient gas-liquid contact, high treatment efficiency, and wide applicability. The core of wet scrubbing lies in ensuring sufficient contact between the acidic gas and the alkaline scrubbing liquid, achieving gas purification through a neutralization reaction. Traditional wet scrubbing equipment often uses a spray tower structure, increasing the gas-liquid contact area and extending the reaction time by setting a packing layer inside the tower, thereby improving treatment efficiency. With the development of automation control technology, intelligent wet scrubbing equipment is gradually becoming more widespread. Control systems such as PLCs allow for real-time adjustment of parameters such as spray volume, liquid level, and pH value, significantly improving the operational stability and ease of use of the equipment.

[0004] However, existing intelligent wet scrubbing equipment still faces an unavoidable technical drawback in long-term operation. The reactants and impurities produced after the neutralization reaction between the scrubbing liquid and acidic gases gradually adhere to the surface of the packing material and accumulate in the gaps between the packing pores, easily causing blockage after prolonged operation. Simultaneously, the packing material, constantly immersed in the scrubbing liquid environment, gradually forms a crystalline layer on its surface; the continuous accumulation of crystals further exacerbates the blockage. As the gaps in the packing material are gradually filled, the flow area for gas passage decreases significantly, and the flow resistance increases dramatically, directly leading to a decline in gas throughput efficiency. This not only directly affects the treatment efficiency of acidic gases but also disrupts the stability of the airflow inside the equipment. Summary of the Invention

[0005] Therefore, it is necessary to provide an intelligent wet treatment device for acidic gases to address the problem that the efficiency of acidic gas treatment gradually decreases due to the gradual blockage of the packing gaps in current intelligent wet treatment equipment during long-term operation.

[0006] The above objectives are achieved through the following technical solutions: An intelligent wet treatment device for acidic gases, comprising: A spray tower is provided for containing alkaline spray liquid and for wet treatment of acidic gases; the spray tower is provided with a feed inlet for conveying packing material into the spray tower. An anti-clogging component is disposed inside the spray tower; the anti-clogging component includes a support unit and a drive unit, the support unit is used to support the packing and allow acidic gas to pass through, and the drive unit is used to provide power to the support unit so that the support unit drives the packing to roll.

[0007] Furthermore, the supporting units are arranged in multiple groups at intervals along the axial direction of the spray tower.

[0008] Furthermore, the supporting unit includes multiple coaxially spaced support plates, which are fixedly connected to each other and detachably connected to the spray tower; along the radial direction of the spray tower, the diameter of the multiple support plates decreases sequentially from the outside to the inside; a partition is coaxially arranged between adjacent support plates, and the partition is rotatably connected to the support plate; multiple radially extending through slots are formed on the partition, and the multiple through slots are evenly spaced circumferentially.

[0009] Furthermore, the plurality of support plates are spaced apart along the axial direction of the spray tower; along the radial direction of the spray tower, the axial height of the plurality of support plates decreases sequentially from the outside to the inside.

[0010] Furthermore, the drive unit includes a motor, a drive gear, and a rotating shaft. The motor is fixedly connected to the innermost support plate, and the output end of the motor is fixedly connected to the drive gear. The rotating shaft meshes with the drive gear and is rotatably connected to multiple support plates. Multiple rotating gears are coaxially fixedly arranged on the rotating shaft, and the multiple rotating gears are distributed at intervals along the axial direction of the rotating shaft. The rotating gears are used to drive the partition plate to rotate around the axial direction of the support plate.

[0011] Furthermore, along the axial direction of the rotating shaft, the diameters of the plurality of rotating gears decrease sequentially from the outside to the inside.

[0012] Furthermore, a conveying structure is provided between adjacent support plates, the conveying structure being used to drive the packing material to circulate radially and axially along the partition plate.

[0013] Furthermore, the conveying structure includes a rubber auger disposed on the surface of the partition plate, and the rubber auger is rotatably connected to both the support plate and the partition plate; each of the multiple support plates is provided with a rotatable mating gear, which is used to drive the rubber auger and the partition plate to rotate in opposite directions.

[0014] Furthermore, a limiting plate is coaxially fixedly provided on each of the support plates, and the rubber auger is rotatably connected to the limiting plate. The limiting plate is used to limit the assembly of the partition and the rubber auger on the support plate.

[0015] Furthermore, it also includes a protective shield for reducing the corrosive effects of acidic gases on the motor, the drive gear, the shaft, and the rotating gear.

[0016] The beneficial effects of this invention are: This invention provides an intelligent wet treatment device for acidic gases, comprising a spray tower and an anti-clogging component. The spray tower contains an alkaline spray solution for wet treatment of the acidic gases, and has an inlet for feeding packing material into the tower. The anti-clogging component is located inside the spray tower and includes a support unit and a drive unit. The support unit supports the packing material and allows the acidic gases to pass through. When the packing material is introduced into the spray tower and falls onto the support unit, it reacts with the acidic gases and the alkaline spray solution. The drive unit provides power to the support unit, causing the packing material to roll during the acidic gas treatment process. This not only allows for dynamic distribution of the packing material on the surface of the support unit, preventing localized accumulation, but also enables surface self-cleaning through friction between the packing particles. Simultaneously, the relative movement between the packing material and the support unit during rolling provides continuous cleaning to the support unit, effectively inhibiting packing blockage and crystallization, preventing blockage of the acidic gas flow, ensuring smooth flow of the acidic gas through the packing material and support unit, and thus improving the acidic gas treatment efficiency.

[0022] The following reference Figures 1 to 17This invention describes an intelligent wet treatment device for acidic gases provided in an embodiment of the invention. The intelligent wet treatment device for acidic gases includes a spray tower 100. The top of the spray tower 100 has an outlet 105, and near the bottom of the spray tower 100 has an inlet 104. A feed inlet 101 for adding packing material is located on the side wall of the spray tower 100. An anti-clogging component is installed inside the spray tower 100, located between the feed inlet 101 and the inlet 104. This anti-clogging component includes a support unit 200 for supporting the packing material. After the packing material is added through the feed inlet 101, it falls onto the support unit 200. Acidic gas enters the spray tower 100 from the inlet 104 and rises to the support unit 200. The support unit 200 allows the acidic gas to pass through, thereby contacting the packing material and reacting with it. Multiple nozzles 106 are fixedly installed inside the spray tower 100, mounted above the support unit 200, for spraying alkaline scrubbing liquid. Acidic gas that is not completely purified by the packing material comes into contact with and reacts with the alkaline scrubbing liquid during its ascent. The treated gas is then discharged through outlet 105. Furthermore, the intelligent wet treatment equipment for acidic gas also includes a spray pipe 102 and a circulation device 103. The circulation device 103 is fixedly installed on the outside of the spray tower 100. One side of the circulation device 103 is connected to the nozzle 106 via the spray pipe 102, and the other side is connected to the bottom of the spray tower 100. When the alkaline scrubbing liquid passes through the packing material and the support unit 200 and falls to the bottom of the spray tower 100, the circulation device 103 can circulate it back to the nozzle 106, realizing the recycling of the alkaline scrubbing liquid.

[0023] Furthermore, the anti-clogging component also includes a drive unit. The drive unit provides power to the carrier unit 200, enabling the carrier unit 200 to drive the packing material to roll during acid gas treatment. This rolling of the packing material achieves dynamic distribution on the surface of the carrier unit 200, preventing localized accumulation; it also achieves surface self-cleaning through the mutual friction between the packing particles; simultaneously, the relative movement between the packing material and the carrier unit 200 during rolling provides continuous cleaning for the carrier unit 200, thereby effectively inhibiting packing blockage and crystallization, preventing blockage of acid gas flow, ensuring smooth flow of acid gas through the packing material and carrier unit 200, and thus improving acid gas treatment efficiency.

[0024] In one embodiment, the support units 200 and drive units are arranged in multiple groups along the axial direction of the spray tower 100. Correspondingly, multiple groups of feed inlets 101 are also opened along the axial direction, and a nozzle 106 is provided above each support unit 200. Therefore, during the ascent, the acidic gas sequentially contacts and reacts with each layer of packing and the alkaline spray liquid, forming a multi-stage treatment structure, further improving the treatment efficiency of the acidic gas. At the same time, each drive unit independently drives the packing on the corresponding support unit 200 to roll, effectively suppressing the clogging and crystallization of each layer of packing, ensuring the long-term stable operation of the equipment.

[0025] In one embodiment, the supporting unit 200 includes a fixing rod 202 and a plurality of coaxially spaced support plates 201. The support plates 201 are coaxially arranged inside the spray tower 100 and sequentially arranged radially along the spray tower 100. The diameter of the support plates 201 gradually decreases radially from the outside to the inside of the spray tower 100, and the outermost support plate 201 is detachably connected to the inner wall of the spray tower 100. The fixing rod 202 is fixedly connected to each support plate 201. A partition 203 is coaxially arranged between adjacent support plates 201, and the partition 203 is rotatably connected to the support plate 201. The partition 203 has a plurality of through slots 204 extending radially along the spray tower 100, the through slots 204 being evenly spaced circumferentially and penetrating the partition 203 axially along the spray tower 100.

[0026] Specifically, the packing material falls onto the baffle plate 203 through the inlet 101. The width of the channel 204 is smaller than the diameter of the packing material, so the channel 204 only allows acidic gas and sprayed alkaline spray liquid to flow through. When the acidic gas passes through the channel 204 and reacts with the packing material and alkaline spray liquid, the baffle plate 203 can rotate relative to the support plate 201 around its own axis, thereby causing the packing material to roll. The rolling of the packing material can achieve dynamic distribution on the surface of the baffle plate 203, avoiding local accumulation; on the other hand, the mutual friction between the packing particles achieves surface self-cleaning. At the same time, the relative movement between the packing material and the baffle plate 203 during the rolling process can also continuously clean the channel 204, thereby effectively inhibiting packing blockage and crystallization, avoiding blockage of the flow of acidic gas, ensuring the smooth flow of acidic gas through the packing material and channel 204, and thus improving the acidic gas treatment efficiency.

[0027] In one embodiment, a plurality of support plates 201 are spaced apart along the axial direction of the spray tower 100; along the radial direction of the spray tower 100, the axial height of the plurality of support plates 201 decreases sequentially from the outside to the inside, that is, the distance between the support plate 201 closer to the middle of the spray tower 100 and the bottom of the spray tower 100 is smaller, so that the plurality of support plates 201 and the plurality of partitions 203 together form a conical structure that protrudes towards the bottom of the spray tower 100.

[0028] Specifically, in actual operation, the spray tower 100 has a relatively large structural size and typically uses single-sided air intake, which easily leads to the flow deviation of acidic gases. That is, the flow velocity of acidic gases in the middle of the spray tower 100 is higher than that near the sidewalls, resulting in uneven distribution of acidic gases and affecting the acidic gas treatment efficiency. Therefore, since the multiple support plates 201 and multiple baffles 203 are collectively arranged in a conical structure convex towards the bottom of the spray tower 100, the material volume in the middle of the conical structure is greater than that on the outer side. This effectively reduces the flow velocity of acidic gases in the middle region, reduces the velocity difference of acidic gases inside the spray tower 100, thereby prolonging the residence time of acidic gases with the packing material and alkaline spray liquid located in the middle of the conical structure, and improving the contact reaction effect. At the same time, the conical structure facilitates the flow of alkaline spray liquid, reduces liquid residue on the surface of the baffles 203, and avoids liquid accumulation. In addition, the conical structure allows the baffle 203 to drive more packing material to roll, further enhancing the cleaning effect and thus comprehensively improving the efficiency of acid gas treatment.

[0029] In one embodiment, the drive unit includes a motor 311, a drive gear 312, and a rotating shaft 313. A conical frame 302 is fixedly installed on the innermost support plate 201 near the bottom of the spray tower 100. The conical frame 302 can seal the support plate 201 to prevent packing leakage. The motor 311 is fixedly connected to the conical frame 302, and the output end of the motor 311 is fixedly connected to the drive gear 312. The rotating shaft 313 is rotatably connected to multiple support plates 201, and the rotating shaft 313 maintains a parallel and spaced-apart state with the fixed rod 202. One section of the rotating shaft 313 is meshed with the drive gear 312 for transmission. Multiple rotating gears 314 are coaxially fixedly installed on the rotating shaft 313, and the multiple rotating gears 314 are distributed at intervals along the axial direction of the rotating shaft 313. Each partition 203 has a plurality of first driven teeth 316 fixedly arranged on one side. The plurality of first driven teeth 316 are evenly spaced around the circumference, and the first driven teeth 316 on each partition 203 mesh with the corresponding rotating gear 314. Specifically, the motor 311 drives the rotating shaft 313 to rotate around its own axis through the drive gear 312. The rotating shaft 313 drives all the rotating gears 314 to rotate synchronously, and then drives each partition 203 to rotate around its own axis through the first driven teeth 316.

[0030] In one embodiment, along the axial direction of the rotating shaft 313, the diameters of the multiple rotating gears 314 decrease sequentially from the outside to the inside, resulting in different transmission ratios among the multiple rotating gears 314. Consequently, under the drive of the same rotating shaft 313, the rotational speed of the partition 203 decreases sequentially from the outside to the inside. Specifically, the outer partition 203 rotates at a faster speed, ensuring that the packing material on the partition 203 maintains a stable rolling state and ensuring a cleaning effect. The inner partition 203 has a larger packing material accumulation, and the packing material itself experiences greater gravity, resulting in greater pressure on the partition 203. If the inner partition 203 rotates at a faster speed, it is prone to damage to the partition 203 and the packing material itself. Therefore, ensuring that the inner partition 203 rotates at a slower speed ensures the cleaning effect of the packing material rolling while reducing damage to the partition 203 and the packing material itself.

[0031] In one embodiment, a conveying structure is provided between adjacent support plates 201. During the rotation of the partition plate 203, the conveying structure can drive the packing to circulate radially and axially along the partition plate 203, so that the packing can fully contact the acidic gas and alkaline spray liquid, thereby improving the gas-liquid reaction efficiency.

[0032] Furthermore, each conveying structure includes a rubber auger 205 and a connecting rod 206. The rubber auger 205 is spirally arranged on the surface of the partition 203, and is rotatably connected to both the support plate 201 and the partition 203. The connecting rod 206 is used to fix the pitch of the rubber auger 205 itself, ensuring the stability of its rotation. Rotatable engaging gears 315 are provided on multiple support plates 201, located between the rubber auger 205 and the partition 203. Multiple second driven teeth 317 are fixedly provided on the other side of each partition 203. These second driven teeth 317 are evenly spaced circumferentially and mesh with one side of the engaging gear 315. Multiple third driven teeth 318 are fixedly provided on each rubber auger 205. These third driven teeth 318 are evenly spaced circumferentially and mesh with the other side of the engaging gear 315.

[0033] Specifically, when the baffle 203 rotates around its own axis, the baffle 203 drives the mating gear 315 to rotate around its own axis via the second driven gear 317. The mating gear 315 then drives the rubber auger 205 to rotate in the opposite direction to the rotation direction of the baffle 203 via the third driven gear 318. Therefore, guided by the conical structure formed by the multiple support plates 201 and multiple baffles 203 protruding towards the bottom of the spray tower 100, the opposite rotation of the rubber auger 205 and the baffle 203 can drive the packing to circulate along the axial and radial directions of the conical structure, causing the packing to move back and forth between the bottom and top of the cone. This enhances the contact effect between the packing and the acidic gas and alkaline spray liquid, and at the same time, the continuous rolling of the packing further improves the self-cleaning ability and effectively improves the gas-liquid reaction efficiency.

[0034] In particular, the soft rubber material of the rubber auger 205 can effectively buffer the compression and friction on the packing during the process of driving the packing to rise along the conical surface, thereby reducing the damage to the packing.

[0035] In one embodiment, a limiting plate 207 is coaxially fixed on each support plate 201. The rubber auger 205 is rotatably connected to the limiting plate 207. The limiting plate 207 limits the rubber auger 205 and the partition plate 203 on the support plate 201 to prevent the rubber auger 205 and the partition plate 203 from axially dislodging during rotation.

[0036] In one embodiment, the intelligent wet treatment equipment for acidic gases also includes a protective cover 301, which is fixedly connected to the support plate 201 and the conical frame 302, and covers the motor 311, drive gear 312, rotating shaft 313 and rotating gear 314 inside, reducing the corrosion of the motor 311, drive gear 312, rotating shaft 313 and rotating gear 314 by the acidic gas during the rising process, and ensuring its long-term stable operation.

[0037] Furthermore, the protective cover 301 is a fully enclosed structure, which is fastened to the conical frame 302 by sealing gaskets and bolts to form a sealed protective chamber, which houses the motor 311, drive gear 312, rotating shaft 313 and rotating gear 314 inside the protective chamber, completely isolating them from external acidic gases, spray liquids and fillers.

[0038] In one embodiment, the intelligent wet treatment equipment for acidic gases also includes an intelligent control system. This system automatically adjusts the operating state of the drive unit based on the internal operating parameters of the spray tower 100, achieving intelligent control of packing blockage prevention. The intelligent control system includes a parameter detection unit, a control unit, and an execution unit.

[0039] Furthermore, the parameter detection unit includes a differential pressure sensor, a pH sensor, a torque sensor, and a liquid level sensor. The differential pressure sensor is located between the air inlet 104 and the air outlet 105 of the spray tower 100 to detect the pressure difference before and after the acidic gas flows through the packing layer. This pressure difference directly reflects the degree of packing blockage: when the pressure difference increases, it indicates that the blockage in the packing gaps is intensified, and the gas flow resistance increases. The pH sensor is located in the circulating liquid at the bottom of the spray tower 100 to detect the pH value of the alkaline spray liquid in real time and determine the degree of neutralization reaction consumption of the spray liquid. The torque sensor is located on the output shaft of the motor 311 to detect the output torque of the motor 311, indirectly reflecting the load of the packing on the baffle 203 and the degree of packing agglomeration. The liquid level sensor is located on the side wall of the spray tower 100 to monitor the liquid level at the bottom of the spray tower 100, preventing circulating liquid overflow or pump cavitation.

[0040] Furthermore, the control unit includes a PLC controller and a human-machine interface touchscreen. The PLC controller is fixedly installed inside the electrical control box of the circulation device 103 and is electrically connected to the differential pressure sensor, pH sensor, torque sensor, and liquid level sensor, respectively. It is used to receive the operating parameters collected by each sensor and output control commands according to the preset control logic. The human-machine interface touchscreen is installed on the outer surface of the circulation device 103 and is electrically connected to the PLC controller. It is used to display the equipment operating status, set control parameters, and perform manual operation control.

[0041] Furthermore, the execution unit includes a frequency converter and a solenoid valve. The frequency converter is electrically connected to the motor 311 and signal-connected to the PLC controller, used to adjust the speed of the motor 311 according to the instructions of the PLC controller. The solenoid valve is installed on the spray liquid supply pipeline and electrically connected to the PLC controller, used to automatically replenish fresh alkaline spray liquid according to the pH value detection result.

[0042] The control logic of the intelligent control system is as follows: The differential pressure sensor is preset with a first differential pressure value and a second differential pressure value. The first differential pressure value is the normal operation threshold, and the second differential pressure value is the blockage warning threshold. The second differential pressure value is greater than the first differential pressure value. When the detected actual differential pressure is less than or equal to the first differential pressure value, the PLC controller controls the motor 311 to run at the base speed via the frequency converter, maintaining the low-speed rolling of the packing to ensure a basic anti-blocking effect. When the actual differential pressure is between the first and second differential pressure values, the PLC controller controls the motor 311 to increase its speed linearly with the increase of the differential pressure, accelerating the rolling of the packing to enhance the self-cleaning effect. When the actual differential pressure is greater than or equal to the second differential pressure value, the PLC controller controls the motor 311 to run intermittently in both forward and reverse directions at the highest speed. Through the violent rolling and mutual friction of the packing, the agglomerates are quickly broken up and the blockage is cleared. At the same time, a blockage warning prompt is issued on the touch screen.

[0043] A maximum torque value is preset in the torque sensor. When the torque sensor detects that the output torque of the motor 311 exceeds the maximum torque value, it indicates that the packing may be severely stuck or large crystals may be stuck in the partition 203. The PLC controller immediately controls the motor 311 to stop running and starts in reverse several times to try to remove the stuckness. If it still cannot be removed, a fault alarm is issued to prompt the operator to perform a manual inspection to prevent the motor 311 from being overloaded and burned out.

[0044] A lower limit value for pH is preset in the pH sensor. When the pH sensor detects that the pH value of the circulating spray liquid is lower than the lower limit value, it indicates that the alkalinity of the spray liquid is insufficient and the neutralization reaction capacity is reduced. The PLC controller controls the solenoid valve on the supply pipeline to open and automatically replenish fresh high-concentration alkaline spray liquid until the pH value returns to the set range and then closes the solenoid valve.

[0045] The liquid level sensor is preset with high and low liquid level thresholds. When the liquid level exceeds the high liquid level threshold, the PLC controller controls the circulating pump to reduce its speed or stop running to prevent liquid from overflowing. When the liquid level is below the low liquid level threshold, the PLC controller controls the circulating pump to stop running and issues a low liquid level alarm to prevent the pump body from running dry and being damaged.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
