Description

Technical Field

[0001] The invention relates to the technical field of acid mist purification, in particular to an acid mist purification treatment machine based on alkali solution neutralization. Background Art

[0002] With the increasing degree of industrialization, the waste gas pollution problem brought about by it has also attracted more and more attention. These harmful gases must be strictly treated to meet the comprehensive atmospheric emission standards before they can be discharged into the atmosphere. At present, a large amount of acid mist gas is generated during the pickling process of chemical and electroplating production and processing, which pollutes the air and affects health. The acid mist purification tower is a commonly used purification equipment in waste gas treatment projects. Since acidic gases are very harmful to the human body and the environment, these harmful gases must usually be strictly treated to meet the comprehensive atmospheric pollution emission standards before they can be discharged into the atmosphere. Generally, an acid mist purification tower with a spray device is used to spray the acid mist once, and a circulating spray device is used to collect the spray liquid for further use.

[0003] At present, in the process of neutralizing acid mist with alkali solution, a simple spraying method is used so that the acid mist and the alkali solution cannot be fully contacted, so that the harmful components in the acid mist are not removed thoroughly enough. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: an acid mist purification treatment machine based on alkali solution neutralization, comprising a treatment cylinder and a support frame, wherein the treatment cylinder is arranged inside the support frame and fixedly connected to the inner wall of the support frame, and one side of the bottom of the treatment cylinder is connected to an external alkali solution storage device through a connecting pipe, and further comprising:

[0006] A spray device, which is arranged on the top of the treatment barrel and is used to spray the alkali solution into the treatment barrel after atomization, and the spray device penetrates the treatment barrel and is fixedly connected to the treatment barrel;

[0007] An exhaust device is arranged at the top of the treatment tube on one side of the spray device, and is used to discharge the gas processed inside the treatment tube. The exhaust device is connected to the inside of the treatment tube.

[0008] Preferably, the air intake device includes an air intake pipe, one end of the air intake pipe is connected to a diverter plate, the bottom of the diverter plate is connected to a diverter pipe, the inner wall of the diverter pipe is fixedly connected to a spiral fan blade through a bracket, the bottom of the diverter pipe is rotatably connected to an air outlet device, the diverter pipe is connected to the interior of the air outlet device, the bottom of the spiral fan blade is fixedly connected to a connecting rod, the connecting rod extends from one end of the spiral fan blade to the interior of the air outlet device and is fixedly connected to the inner wall of the air outlet device, so that the alkali solution can be evenly contacted with the exhaust gas, thereby achieving better removal of acid mist in the exhaust gas. Since the diverter pipe is set to a shape that is thin in the middle and thick at both ends, the exhaust gas has a faster flow rate when flowing in the thin section inside the diverter pipe, thereby making the driving force of the spiral fan blade stronger, so that the air outlet device can rotate more smoothly.

[0009] Preferably, the diverter plate is arranged inside the treatment cylinder and fixedly connected to the inner wall of the treatment cylinder through a bracket, and the end of the air inlet pipe away from the diverter plate passes through the treatment cylinder and extends to the outside of the treatment cylinder. The end of the air inlet pipe located outside the treatment cylinder is connected to an air pump.

[0010] Preferably, the diverter pipe is configured to be thin in the middle and thick at both ends, and the spiral blades are configured to be located in the middle of the diverter pipe.

[0011] Preferably, the air outlet device includes an air outlet disk, a side of the air outlet disk is connected to an air outlet pipe, an end of the air outlet pipe away from the air outlet disk is connected to an air outlet frame, and a side of the air outlet frame is connected to an elastic hose, which can avoid the situation where the alkali liquid away from the air outlet device cannot be used. At the same time, the irregular movement of the alkali liquid will also promote the irregular bending of the elastic hose, so that the exhaust port direction of the elastic hose is constantly changing, and the air outlet position of the air outlet device is further diversified.

[0012] Preferably, the top of the gas outlet plate is connected to the diverter pipe, the gas outlet frame is a flat rectangular frame, and the gas outlet frame is obliquely arranged inside the processing cylinder.

[0013] Preferably, the spray device includes an annular diverter pipe, the top of the annular diverter pipe is connected to a drain pipe, the top of the drain pipe is connected to a diverter spherical shell, the top of the diverter spherical shell is connected to a liquid inlet pipe, the side of the annular diverter pipe is connected to a hose, the end of the hose away from the annular diverter pipe is connected to an atomizing nozzle, and the top of the liquid inlet pipe is connected to a liquid outlet of a servo pump, so that the atomizing nozzle can spray toward different positions, so that the gas rising from different positions inside the treatment cylinder can be sprayed, the spray treatment is more thorough, and the treatment effect is better.

[0014] Preferably, the side surface of the annular diversion pipe is fixedly connected to the inner wall of the treatment cylinder through a bracket, the top of the liquid inlet pipe passes through the treatment cylinder and extends to the outside of the treatment cylinder, and the liquid inlet of the servo pump is connected to an external alkali solution storage device.

[0015] Preferably, the exhaust device includes an exhaust pipe, the top of the exhaust pipe is connected to an exhaust spherical shell, the top of the exhaust spherical shell is connected to a spiral tube, a fixed sleeve is sleeved and fixedly connected to the exhaust pipe, and a disinfection lamp is fixedly connected to the side of the fixed sleeve. The spiral tube can be arranged to allow the gas to remain in the fixed sleeve for a longer time, so that the disinfection lamp can fully irradiate and disinfect, and the airflow can be divided into multiple streams, and the thickness of a single stream of gas is relatively low, so that the disinfection lamp can better irradiate the gas, thereby avoiding the situation where the light attenuates due to a long distance through the gas and resulting in poor treatment effect.

[0016] Preferably, the bottom of the exhaust pipe is communicated with the top of the treatment tube, and the top of the spiral pipe passes through the fixing sleeve and extends to the outside of the fixing sleeve.

[0017] The present invention provides an acid mist purification treatment machine based on alkali solution neutralization. It has the following beneficial effects:

[0018] 1. The acid mist purification treatment machine based on alkali solution neutralization, when in use, the waste gas enters the inside of the air inlet pipe through the air pump, the waste gas inside the air inlet pipe enters the inside of the diverter plate, the waste gas inside the diverter plate enters the inside of the diverter pipe, and the waste gas flows in the diverter pipe while driving the spiral blades to rotate, and the spiral blades drive the gas outlet device to rotate through the connecting rod. Since the treatment cylinder is filled with alkali solution and the alkali solution level is higher than the gas outlet device, the waste gas can be discharged from different positions into the alkali solution during the rotation of the gas outlet device, so that the alkali solution can be evenly contacted with the waste gas, thereby making it easier to remove the acid mist in the waste gas. Since the diverter pipe is set to be thin in the middle and thick at both ends, the waste gas flows faster when it flows in the thin section inside the diverter pipe, so that the driving force of the spiral blades is stronger, and the gas outlet device can rotate more smoothly.

[0019] 2. The acid mist purification treatment machine based on alkali solution neutralization, when the spiral fan blade drives the connecting rod to rotate, the connecting rod drives the air outlet disk to rotate, the air outlet disk drives the air outlet frame to rotate through the air outlet pipe, the air outlet frame drives the elastic hose to rotate, and the gas inside the air outlet device can be discharged from the elastic hose to different positions inside the treatment tube. Since multiple groups of diverter pipes and air outlet devices are provided, the rotation of multiple groups of air outlet frames inside the alkali solution can drive the irregular movement of the alkali solution, so that the alkali solution at each position can fully contact with the exhaust gas, avoiding the situation that the alkali solution far away from the air outlet device cannot be used. At the same time, the irregular movement of the alkali solution will also promote the irregular bending of the elastic hose, so that the exhaust port direction of the elastic hose is constantly changing, and the air outlet position of the air outlet device is further diversified.

[0020] 3. The acid mist purification treatment machine based on alkali solution neutralization, when the gas discharged into the treatment tube from the air intake device rises after being absorbed by the alkali solution, the servo pump above sends the alkali solution into the liquid inlet pipe, the alkali solution inside the liquid inlet pipe enters the discharge pipe through the diverter ball shell, the alkali solution inside the discharge pipe enters the annular diverter pipe, and the alkali solution inside the annular diverter pipe is sprayed from the atomizing nozzle through the hose, so as to spray the gas rising from the treatment tube, so that the gas after the alkali solution aeration treatment can be sprayed again, so that the acid mist in the gas can be removed more thoroughly, and at the same time, because the water pressure discharged from the servo pump fluctuates, the water pressure inside the hose also fluctuates. When the water pressure is large, the hose is straightened, and when the water pressure is small, the hose is bent, so that the atomizing nozzle can change its direction through the change of the hose state, so that the atomizing nozzle can spray towards different positions, so that the gas rising from different positions inside the treatment tube can be sprayed, the spraying treatment is more thorough, and the treatment effect is better.

[0021] 4. In the acid mist purification treatment machine based on alkali solution neutralization, the waste gas after aeration and spraying treatment enters the exhaust pipe, and is discharged from the exhaust pipe into the exhaust ball shell. The gas inside the exhaust ball shell enters the spiral tube, and is discharged to the outside from the top of the spiral tube. At the same time, the gas can be disinfected by the disinfection lamp while moving inside the spiral tube, thereby completing the re-treatment of the waste gas and making the exhausted gas cleaner. At the same time, a spiral tube is provided, and the gas can be retained in the fixed sleeve for a longer time through the setting of the spiral tube, so that the disinfection lamp can fully irradiate and disinfect, and the airflow is divided into multiple streams. The thickness of a single stream of gas is relatively low, so that the disinfection lamp can better irradiate the gas, avoiding the poor treatment effect caused by attenuation of the light due to the long distance through the gas.

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 creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 5 The present invention provides a technical solution: an acid mist purification treatment machine based on alkali solution neutralization, comprising a treatment cylinder 1 and a support frame 2, wherein the treatment cylinder 1 is arranged inside the support frame 2 and is fixedly connected to the inner wall of the support frame 2, and one side of the bottom of the treatment cylinder 1 is connected to an external alkali solution storage device through a connecting pipe, and further comprising:

[0033] An air intake device 3 is arranged inside the treatment tube 1. The air intake device 3 is used to discharge the flyaways to be treated into the treatment tube 1. The air intake device 3 is fixedly connected to the inner wall of the treatment tube 1 through a bracket. The air intake end of the air intake device 3 penetrates the treatment tube 1 and extends to the outside of the treatment tube 1.

[0034] A spray device 4, which is arranged on the top of the treatment tube 1, and is used to spray the alkali solution into the treatment tube 1 after atomization. The spray device 4 passes through the treatment tube 1 and is fixedly connected to the treatment tube 1;

[0035] An exhaust device 5 is arranged at the top of the treatment tube 1 on one side of the spray device 4. The exhaust device 5 is used to discharge the gas processed inside the treatment tube 1. The exhaust device 5 is connected to the inside of the treatment tube 1;

[0036] The air intake device 3 includes an air intake pipe 31, one end of the air intake pipe 31 is connected to a diverter plate 32, the bottom of the diverter plate 32 is connected to a diverter pipe 33, the inner wall of the diverter pipe 33 is fixedly connected to a spiral blade 34 through a bracket, the bottom of the diverter pipe 33 is rotatably connected to an air outlet device 35, the diverter pipe 33 is connected to the inside of the air outlet device 35, the bottom of the spiral blade 34 is fixedly connected to a connecting rod 36, the end of the connecting rod 36 away from the spiral blade 34 extends to the inside of the air outlet device 35 and is fixedly connected to the inner wall of the air outlet device 35, the diverter plate 32 is arranged in the processing tube 1 and is fixedly connected to the inner wall of the processing tube 1 through the bracket, the end of the air intake pipe 31 away from the diverter plate 32 passes through the processing tube 1 and extends to the outside of the processing tube 1. The end of the air intake pipe 31 located outside the processing tube 1 is connected to an air pump, the diverter pipe 33 is set to a shape that is thin in the middle and thick at both ends, and the spiral blade 34 is set in the middle position inside the diverter pipe 33;

[0037] During use, the exhaust gas enters the air inlet pipe 31 through the air pump, the exhaust gas inside the air inlet pipe 31 enters the diverter plate 32, and the exhaust gas inside the diverter plate 32 enters the diverter pipe 33. While the exhaust gas flows in the diverter pipe 33, it drives the spiral blades 34 to rotate, and the spiral blades 34 drive the gas outlet device 35 to rotate through the connecting rod 36. Since the treatment cylinder 1 is filled with alkali solution, and the liquid level of the alkali solution is higher than the gas outlet device 35, the exhaust gas can be discharged into the alkali solution from different positions during the rotation of the gas outlet device 35, so that the alkali solution can be evenly contacted with the exhaust gas, thereby making it easier to remove the acid mist in the exhaust gas. Since the diverter pipe 33 is set to a shape that is thin in the middle and thick at both ends, the exhaust gas flows in the thin section of the diverter pipe 33 at a faster flow rate, thereby making the driving force of the spiral blades 34 stronger, so that the gas outlet device 35 can rotate more smoothly.

[0038] The gas outlet device 35 includes a gas outlet plate 351, a gas outlet pipe 352 is connected to the side of the gas outlet plate 351, and one end of the gas outlet pipe 352 away from the gas outlet plate 351 is connected to the gas outlet frame 353, and an elastic hose 354 is connected to the side of the gas outlet frame 353. The top of the gas outlet plate 351 is connected to the diverter pipe 33. The gas outlet frame 353 is a flat rectangular frame, and the gas outlet frame 353 is tiltedly arranged inside the processing cylinder 1;

[0039] When the spiral fan blades 34 drive the connecting rod 36 to rotate, the connecting rod 36 drives the air outlet disk 351 to rotate, and the air outlet disk 351 drives the air outlet frame 353 to rotate through the air outlet pipe 352, and the air outlet frame 353 drives the elastic hose 354 to rotate, and the gas inside the air outlet device 35 can be discharged from the elastic hose 354 to different positions inside the treatment tube 1. Since the diverter pipe 33 and the air outlet device 35 are both provided with multiple groups, the rotation of multiple groups of air outlet frames 353 inside the alkali liquid can drive the irregular movement of the alkali liquid, so that the alkali liquid at each position can fully contact with the exhaust gas, avoiding the situation where the alkali liquid far away from the air outlet device 35 cannot be used. At the same time, the irregular movement of the alkali liquid will also promote the irregular bending of the elastic hose 354, so that the exhaust port direction of the elastic hose 354 is constantly changing, and the air outlet position of the air outlet device 35 is further diversified.

[0040] See also Figure 1-Figure 6 The present invention provides a technical solution: the spray device 4 includes an annular diverter pipe 41, the top of the annular diverter pipe 41 is connected to a drain pipe 42, the top of the drain pipe 42 is connected to a diverter ball shell 43, the top of the diverter ball shell 43 is connected to a liquid inlet pipe 44, the side of the annular diverter pipe 41 is connected to a hose 45, one end of the hose 45 away from the annular diverter pipe 41 is connected to an atomizing nozzle 46, the top of the liquid inlet pipe 44 is connected to a liquid outlet of a servo pump 47, the side of the annular diverter pipe 41 is fixedly connected to the inner wall of the treatment tube 1 through a bracket, the top of the liquid inlet pipe 44 penetrates the treatment tube 1 and extends to the outside of the treatment tube 1, and the liquid inlet of the servo pump 47 is connected to an external alkali solution storage device;

[0041] When the gas discharged from the air intake device 3 into the treatment tube 1 rises after being absorbed by the alkali solution, the servo pump 47 above delivers the alkali solution into the liquid inlet pipe 44, and the alkali solution in the liquid inlet pipe 44 enters the liquid discharge pipe 42 through the diverter ball shell 43, and the alkali solution in the liquid discharge pipe 42 enters the annular diverter pipe 41, and the alkali solution in the annular diverter pipe 41 is sprayed out from the atomizing nozzle 46 through the hose 45, so as to spray the gas rising from the treatment tube 1, so that the gas after the alkali solution aeration treatment can be sprayed again. At the same time, due to the fluctuating water pressure discharged from the servo pump 47, the water pressure inside the hose 45 also fluctuates. When the water pressure is high, the hose 45 is straightened, and when the water pressure is low, the hose 45 is bent. Thus, the change in the state of the hose 45 can drive the atomizing nozzle 46 to change its direction, so that the atomizing nozzle can spray toward different positions, making it convenient for the gases rising from different positions inside the treatment tube 1 to be sprayed, and the spraying treatment is more thorough, with better treatment effect.

At the same time, the gas can be disinfected by the disinfection lamp 55 while moving inside the spiral tube 53, thereby completing the re-treatment of the waste gas and making the discharged gas cleaner. At the same time, the spiral tube 53 is provided. The gas can be retained in the fixed sleeve 54 for a longer time through the setting of the spiral tube 53, so that the disinfection lamp 55 can fully irradiate and disinfect, and divide the airflow into multiple streams. The thickness of a single stream of gas is relatively low, so that the disinfection lamp 55 can better irradiate the gas, avoiding the situation where the light is attenuated due to the long distance through the gas and resulting in poor treatment effect.
