Description

Technical Field

[0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to an acidic exhaust gas washing tower. Background Art

[0002] A scrubber is a new type of gas purification equipment, which is widely used in pre-treatment systems for industrial waste gas purification and dust removal. Since its working principle is similar to the washing process, it is named a scrubber. In the treatment of acidic waste gas emitted by industry, the scrubber is a widely used purification equipment. Its original design intention is to effectively neutralize or absorb the acidic components in the waste gas through sufficient contact and reaction between the liquid and the waste gas, so as to achieve the purpose of purifying the air and reducing environmental pollution.

[0003] However, traditional scrubber systems often face a technical challenge in practical applications, that is, various non-target impurities (such as dust, particulate matter, etc.) carried in the exhaust gas have not been properly pretreated. These impurities enter the scrubber together with the acidic exhaust gas. Not only may they directly reduce the absorption efficiency of the purified liquid for acidic components, but they are also prone to deposition and accumulation in the piping system and the purified liquid circulation loop in the tower, thereby causing system blockage problems and forcing the system to be frequently shut down for cleaning, seriously affecting the exhaust gas treatment efficiency. In addition, the long-term presence of impurities in the purified liquid may also cause the quality of the purified liquid to deteriorate, thereby weakening the purification ability of the acidic exhaust gas, forming a vicious circle; therefore, there are deficiencies and it cannot meet the purification needs. Therefore, further improvements are necessary.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an acid exhaust gas washing tower is provided, in order to achieve a more practical purpose. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides an acidic exhaust gas scrubber, which is achieved by the following specific technical means:

[0006] An acid exhaust scrubber comprises a base, a scrubber body and a circulation purification mechanism arranged on the base, an air intake duct arranged on the left side of the scrubber body and an exhaust duct arranged on the scrubber body, and an air intake fan and a limiting mechanism arranged inside the air intake duct;

[0007] The limiting mechanism comprises a sealing shell, wherein a dust collecting component for absorbing dust particles in the acidic waste gas and a dust removal component for cleaning dust particles on the surface of the dust collecting component are arranged inside the sealing shell;

[0009] A transmission assembly is arranged on the right side of the air intake fan, and the transmission assembly includes a transmission rod. One end of the transmission rod away from the air intake fan extends to the limiting mechanism and is fixedly connected to the dust removal assembly. When the air intake fan is running, the transmission rod is driven to drive the dust removal assembly to rotate and clean the dust particles on the surface of the dust collection assembly.

[0010] As a further description of the above technical solution: in the process of conveying the acidic exhaust gas to the washing tower body through the air intake fan, the dust suction component is used to collect the dust particles in the exhaust gas, and the dust removal component is used to automatically clean the dust particles on the surface of the dust collecting electrode, so as to achieve the pretreatment of the acidic exhaust gas before purification, and effectively filter and pre-treat the acidic exhaust gas containing dust particles. Through this setting, the dust particles and other impurities entrained in the acidic exhaust gas can be effectively removed before the acidic exhaust gas enters the washing tower body, which fundamentally solves the problem that traditional washing towers are difficult to handle impurities in the exhaust gas, avoids the direct entry of impurities into the washing liquid, resulting in a decrease in purification efficiency and the risk of clogging the circulation system, thereby ensuring the purity and efficiency of the subsequent purification process.

[0011] Furthermore, the circulation purification mechanism includes a circulation box fixedly mounted on the right side of the washing tower body, a circulation pump fixedly mounted on the rear side of the circulation box, and a circulation pipe fixedly mounted on the circulation pump;

[0012] A filter sleeve is fixedly mounted on the wall of the washing tower body facing the circulation box, the washing tower body and the circulation box are in liquid communication through the filter sleeve, and a scale bar for observing the water level of the purified liquid is provided on the front side of the circulation box;

[0013] The circulation purification mechanism also includes two spray components and a filler component arranged inside the washing tower body, and the two spray components and the filler component are arranged in two layers.

[0014] As a further description of the above technical solution: the purification liquid is evenly sprayed onto the filling layer through the spray head, so that it is fully in contact with the rising acidic waste gas, effectively promoting the full mixing and reaction of the gas and liquid, thereby improving the purification effect of the waste gas.

[0015] Furthermore, the spray assembly includes a main pipe, one end of which extends to the outside of the washing tower body and is fixedly connected to the circulation pipe, a plurality of branch pipes are fixedly installed on the main pipe, and the bottom of the main pipe and the branch pipe are fixedly installed with spray heads for spraying purification liquid.

[0016] As a further description of the above technical solution: a circulation pump is used to transfer the purified liquid inside the circulation box along the circulation pipe to the spray assembly, and then the purified liquid is sprayed out by the coordinated action of the main pipe, the branch pipe and the spray head. This setting can ensure that the spray head can spray the purified liquid evenly on the filling layer, thereby improving the purification efficiency of the exhaust gas.

[0017] Furthermore, the packing assembly includes a fixing frame fixedly mounted on the inner wall of the washing tower body, and a filling layer for purifying the acidic waste gas is arranged on the fixing frame, and the purification liquid is evenly sprayed on the filling layer through the spray head to form a continuous liquid film or droplets, which fully contact with the rising acidic waste gas for mixing reaction.

[0018] As a further description of the above technical solution: the purification liquid is evenly sprayed onto the filling layer through the spray head to form a continuous liquid film or droplets, which are fully in contact with the rising acidic waste gas. The filling layer is used to increase the gas-liquid contact area, promote the full mixing and reaction of gas and liquid, and thus enhance the purification effect of the waste gas.

[0019] Further, an air inlet passage is provided in the sealing shell, a sealing plate is provided inside the sealing shell and on the right side of the air inlet passage, the left side of the sealing plate is in close contact with the sealing shell wall, two grooves are provided inside the sealing shell, a connecting ring sleeve is slidably installed in one of the grooves, and an elastic rubber ring is fixedly installed in the other groove, and the right sides of the connecting ring sleeve and the elastic rubber ring are fixedly connected to the sealing plate;

[0020] The limiting mechanism also includes a sliding rheostat, and the sliding rheostat is arranged inside the sealing shell, a sliding plate is slidably mounted on the sliding rheostat, and one side of the sliding plate is fixedly connected to the connecting ring sleeve;

[0021] Wherein, the sealing plate is provided with ventilation holes, and the ventilation holes include a first channel and a second channel, and the inner diameter of the first channel is greater than the inner diameter of the second channel.

[0022] As a further description of the above technical solution: through the cooperation of the sealing shell, the sealing plate and the elastic rubber ring, the leakage of the exhaust gas can be isolated, thereby improving the purification effect of the exhaust gas, and because the inner diameter of the first channel is larger than the inner diameter of the second channel, when the exhaust gas passes through the smaller inner diameter of the second channel, the flow rate of the exhaust gas will be accelerated due to the smaller cross-sectional area, thereby effectively accelerating the circulation speed of the exhaust gas, thereby improving the exhaust gas transportation efficiency.

[0023] Furthermore, the transmission assembly also includes a fixed bracket fixedly mounted inside the intake fan, a reducer is fixedly mounted on the fixed bracket, a drive shaft is provided and connected between the intake fan and the reducer, and the right output end of the reducer is fixedly connected to the transmission rod.

[0024] As a further description of the above technical solution: the drive shaft and the transmission shaft are driven to rotate by the fan blades of the air intake fan to realize the transmission of the transmission shaft, and the rotation speed of the transmission rod is reduced by the setting of the reducer to achieve the purpose of reducing the rotation speed of the transmission shaft.

[0025] Furthermore, the dust collection assembly also includes a fixing ring fixedly mounted on the mounting frame, and a fixing protrusion is fixedly mounted on a side of the fixing ring facing the discharge electrode;

[0026] Wherein, a dustproof cloth for blocking dust particles is fixedly installed inside the fixed shell and on the right side of the mounting frame.

[0027] As a further description of the above technical solution: the provision of a dustproof cloth further strengthens the filtration of dust particles in the exhaust gas, effectively avoiding the risk of reduced purification efficiency and clogging of the circulation system caused by impurities entering the washing liquid, thereby ensuring the purity and efficiency of the subsequent purification process.

[0028] Furthermore, the dust removal assembly includes three dust removal rods fixedly installed in a ring shape and equidistantly at the right end of the transmission rod. The three transmission rods are rotatably mounted with movable sleeves, and the movable sleeves are fixedly mounted with dust removal brushes for cleaning dust particles. The dust removal brushes are configured to be made of ultrafine fiber material that can clean dust particles.

[0029] As a further description of the above technical solution: this setting makes it possible to efficiently collect and fix the dust particles on the surface of the dust collecting electrode to prevent them from scattering and flying back into the exhaust gas. Secondly, the ultrafine fiber material not only has a strong adsorption capacity, but also has a soft texture and will not scratch or damage the surface of the dust collecting electrode, further improving its use effect.

[0030] Furthermore, a swing assembly is fixedly installed at one end of the dust removal rod, and the swing assembly includes a swing sleeve fixedly installed on the dust removal rod, a vibration connecting plate is arranged inside the swing sleeve, a vibration spring is fixedly connected between the swing sleeve and the vibration connecting plate, and a fixing part is fixedly installed on the side of the vibration connecting plate facing the fixed ring. When the swing sleeve and the vibration connecting plate are driven to rotate by the dust removal rod, a vibration frequency is generated by the contact between the fixing part and the fixed protrusion, and the vibration connecting plate is driven to vibrate and knock the dust removal brush, so that the dust removal brush continuously changes the cleaning direction to perform the cleaning operation.

[0031] As a further description of the above technical solution: through this arrangement, the dust removal brush can continuously change the cleaning angle when cleaning and scraping the dust particles on the surface of the dust collecting electrode, thereby enhancing the cleaning effect of the dust particles on the surface of the dust collecting electrode.

[0032] Furthermore, a plurality of door bodies are provided on the front side of the washing tower body, and an exhaust fan for discharging the purified gas is fixedly mounted on the inner wall of the exhaust duct.

[0033] As a further description of the above technical solution: after the gas purification is completed, the purified gas can be driven by the exhaust fan to be discharged into the outside air along the exhaust pipe, thus ensuring that the discharged gas will not harm people's health and pollute the environment.

[0034] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0035] 1. The acidic exhaust gas scrubber, through the cooperation between the air intake fan, the limiting mechanism, the transmission component, the dust suction component and the dust removal component, uses the dust suction component to collect dust particles in the exhaust gas during the process of the air intake fan conveying the acidic exhaust gas to the scrubber body, and uses the dust removal component to automatically clean the dust particles on the surface of the dust collecting electrode, thereby achieving pretreatment of the acidic exhaust gas before purification, effectively filtering and pre-treating the acidic exhaust gas containing dust particles, and through this setting, before the acidic exhaust gas enters the scrubber body, the dust particles and other impurities entrained therein can be effectively removed, so that the problem that the traditional scrubber is difficult to handle impurities in the exhaust gas is fundamentally solved, and the risk of decreased purification efficiency and blockage of the circulation system caused by impurities directly entering the scrubbing liquid is avoided, thereby ensuring the purity and efficiency of the subsequent purification process.

[0036] 2. The acidic exhaust gas washing tower is provided with a first channel and a second channel in the vent hole on the sealing plate. Since the inner diameter of the first channel is larger than the inner diameter of the second channel, when the exhaust gas passes through the second channel with a smaller inner diameter, the flow rate of the exhaust gas will be accelerated due to the smaller cross-sectional area, thereby effectively accelerating the circulation speed of the exhaust gas, thereby improving the exhaust gas transportation efficiency. At the same time, by utilizing the cooperation of the sealing shell, the sealing plate and the elastic rubber ring, when the intake fan stops transporting the exhaust gas, the elastic force of the elastic rubber ring pulls the sealing plate and the sealing shell to close, which can isolate the leakage of the exhaust gas and further improve the exhaust gas purification effect.

[0037] 3. The acidic exhaust gas washing tower, through the cooperation between the air intake fan, the transmission component, the dust suction component, the dust removal component and the swing component, based on the force when the swing component rotates, the rotating fixed part will come into contact with the fixed protrusion on the fixed ring, so that the vibration connecting plate generates a vibration frequency under the elastic force of the vibration spring, and the vibrating vibration connecting plate is used to vibrate and knock the dust removal brush, so that the dust removal brush generates a vibration frequency synchronously, so that the dust removal brush continuously changes the cleaning angle when cleaning and scraping the dust particles on the surface of the dust collecting electrode, thereby enhancing the cleaning effect of the dust particles on the surface of the dust collecting electrode.

In the process of waste gas intake, based on the force of the air intake fan 40 when it is running, the waste gas passes through the air intake channel 511 and impacts the sealing plate 52, so that the sealing plate 52 pulls the elastic rubber ring 54 to move, so that the sealing plate 52 and the wall of the sealing shell 51 are separated from each other. At this time, the wind drives the waste gas to pass through the vent hole 521, and through the first channel 521 provided in the vent hole 521 1 and the second hole 5212. Since the inner diameter of the first hole 5211 is larger than the inner diameter of the second hole 5212, when the exhaust gas passes through the second hole 5212 with a smaller inner diameter, the flow rate of the exhaust gas will be accelerated due to the smaller cross-sectional area, thereby effectively accelerating the circulation speed of the exhaust gas, thereby improving the exhaust gas transportation efficiency; and through the cooperation of the sealing shell 51, the sealing plate 52 and the elastic rubber ring 54, when the intake fan 40 stops the transportation of the exhaust gas, the elastic force of the elastic rubber ring 54 pulls the sealing plate 52 and the sealing shell 51 to close, which can isolate the leakage of the exhaust gas and further improve the exhaust gas purification effect;

[0077] At the same time, the discharge electrode 74 is controlled by the program to discharge. When the exhaust gas containing dust particles enters the electric field area through the vent hole 521, the high-energy electrons generated by the discharge electrode 74 under the action of high voltage will collide with the gas molecules, causing the gas molecules to be ionized into positive and negative ions. When the dust particles in the exhaust gas pass through the electric field, they collide with the positive and negative ions generated by the ionization, thereby being charged. Under the action of the electric field force, the charged dust particles are brought close to the dust collecting electrode 72. Due to the electrostatic adsorption, they are firmly adsorbed on the surface of the dust collecting electrode 72, thereby realizing the collection of dust particles in the exhaust gas.

[0078] In addition, when the exhaust gas pushes the sealing plate 52 to move, it also pulls the connecting ring 53 to move, and the connecting ring 53 moves while driving the slider 551 to slide on the sliding rheostat 55. The device electrically connects the sliding rheostat 55 to the discharge electrode 74, wherein the sliding distance of the slider 551 is inversely related to the change in resistance value. When the slider 551 slides on the sliding rheostat 55, as the sliding distance increases, the resistance value of the entire sliding rheostat 55 also decreases. When the power supply voltage remains constant, according to Ohm's law, the current in the circuit is inversely proportional to the resistance, so the reduction in resistance will lead to an increase in current. Therefore, the resistance value of the sliding rheostat 55 can be accurately controlled by adjusting the sliding distance of the slider 551, thereby The current in the discharge electrode 74 circuit is regulated; when the wind is strong, the thrust on the sealing plate 52 is increased, and the exhaust gas and dust particles passing through the vent 521 increase synchronously. The sliding distance of the slider 551 on the sliding rheostat 55 increases, which increases the current of the discharge electrode 74, thereby enhancing the collection effect of the dust particles in the exhaust gas. When the wind is weak, the thrust on the sealing plate 52 is reduced, and the exhaust gas and dust particles passing through the vent 521 decrease synchronously. The sliding distance of the slider 551 on the sliding rheostat 55 decreases, which reduces the current of the discharge electrode 74, so that the dust particles in the exhaust gas can be collected while avoiding the waste of electric energy, thereby further improving the collection effect of the dust particles in the exhaust gas.

[0079] During the operation of the air intake fan 40, the fan blades of the air intake fan 40 are used to drive the drive shaft 63 and the transmission shaft to rotate, and the speed of the transmission rod 64 is reduced by the setting of the reducer 62 to achieve the purpose of reducing the speed of the transmission shaft, and the transmission shaft drives the dust removal rod 81 to rotate synchronously while rotating, and the dust removal brush 83 on the dust removal rod 81 is used to clean the dust particles on the surface of the dust collecting electrode 72, and by setting the dust removal brush 83 to be a superfine fiber material, the unique structure of the superfine fiber material can be used to give the superfine fiber material a strong adsorption ability. During the cleaning process, the dust removal brush 83 can efficiently collect and fix the dust particles on the surface of the dust collecting electrode 72 to prevent them from scattering and flying back into the exhaust gas. Secondly, the superfine fiber material not only has a strong adsorption ability, but also has a soft texture, and will not cause scratches or damage to the surface of the dust collecting electrode 72, further improving its use effect;

[0080] The dust removal brush 83 is driven by the dust removal rod 81 to move, and the dust removal rod 81 drives the swing assembly 90 to move synchronously. Based on the force of the swing assembly 90 when rotating, the rotating fixing member 94 comes into contact with the fixing protrusion 751 on the fixing ring 75, so that the vibration connecting plate 92 generates a vibration frequency under the elastic force of the vibration spring 93, and the vibrating vibration connecting plate is used to vibrate and knock the dust removal brush 83, so that the dust removal brush 83 generates a vibration frequency synchronously, so that the dust removal brush 83 continuously changes the cleaning angle when cleaning and scraping the dust particles on the surface of the dust collecting electrode 72, thereby enhancing the cleaning effect of the dust particles on the surface of the dust collecting electrode 72;

[0081] When the waste gas is transmitted to the inside of the washing tower body 20, the circulation pump 32 is driven by the program control to generate kinetic energy and start running. The circulation pump 32 is used to transmit the purified liquid in the circulation box 31 along the circulation pipe 33 to the spray assembly 35, and then the main pipe 351, the branch pipe 352 and the spray head 353 are used to spray the purified liquid and spray it evenly on the filling layer 362 to form a continuous liquid film or droplets, which are fully in contact with the rising acidic waste gas. The filling layer 362 is used to increase the gas-liquid contact area, promote the full mixing and reaction of the gas and the liquid, and the purified liquid after mixing is sprayed out. The liquid is then transported along the filter sleeve 34 to the circulation box 31, and the circulation pump 32 is used to extract the purified liquid from the circulation box 31 and transport it to the spray assembly 35, so that it can be circulated. By arranging the spray assembly 35 and the filler assembly 36 with two layers, the purpose of strengthening the purification of the acidic waste gas can be achieved, and the purified liquid can be replaced regularly; and when the gas purification is completed, the purified gas is driven by the exhaust fan 23 to be discharged to the outside air along the exhaust pipe 22, thereby ensuring that the discharged gas will not harm people's health and pollute the environment.
