Technical Field

[0001] This utility model relates to the field of calcium hydroxide processing technology, specifically to a calcium hydroxide processing desulfurization treatment device. Background Technology

[0002] Calcium hydroxide can be produced by reacting calcium oxide with water in a carbon dioxide-free environment, or by reacting calcium salts (such as calcium nitrate) with strong bases (such as potassium hydroxide) in a carbon dioxide-free environment, followed by filtration and drying. Calcium hydroxide can be used in the manufacture of cement and furnace linings, as a binding material in the construction industry; as a flux in the metallurgical industry; in industrial manufacturing, it can be used in sugar refining, leather tanning, and glass manufacturing; in the food industry, it can be used as an acidity regulator, and soaking fruits and vegetables in lime water can help maintain their crispness; in the pharmaceutical field, calcium hydroxide can inhibit bacterial growth, neutralize acidic products of inflammation, and recalcify softened and demineralized dentin.

[0003] A search revealed a Chinese patent document disclosing a dry flue gas desulfurization device using calcium hydroxide [Announcement No.: CN219942346U]. This device includes a desulfurization reaction tower, with an inlet pipe connected to the lower end and an outlet pipe connected to the upper end. An induced draft fan and a calcium hydroxide conveying system are sequentially installed on the inlet pipe. The desulfurization reaction tower is connected to a dust collector via the outlet pipe, and the dust collector is connected to a dust collection fan. The desulfurization reaction tower includes an outer cylinder connected to the outlet pipe and an inner cylinder vertically arranged inside the outer cylinder. The top of the inner cylinder is open, and a connecting pipe is vertically installed at the bottom of the inner cylinder, with the bottom end of the connecting pipe connected to the inlet pipe. This utility model provides a dry flue gas desulfurization device using calcium hydroxide, employing a novel desulfurization reaction tower, resulting in high utilization of the calcium hydroxide desulfurizing agent and excellent desulfurization effect.

[0004] Desulfurization devices are used to treat flue gas during the processing of calcium hydroxide. The most common desulfurization device is the desulfurization tower, which desulfurizes the flue gas by spraying. However, during the desulfurization process, there are often blind spots in the spraying, which prevent the sprayed water from fully contacting the flue gas and thus affect the desulfurization effect. Utility Model Content

[0005] The purpose of this invention is to provide a desulfurization treatment device for calcium hydroxide processing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a calcium hydroxide processing desulfurization treatment device, comprising a desulfurization tower body, a water tank fixedly connected to one side of the desulfurization tower body, a water pump fixedly installed on the top of the water tank, a main pipe fixedly connected to the outlet end of the water pump, a diversion pipe provided inside the desulfurization tower body, one end of the diversion pipe penetrating into the interior of the main pipe, a plurality of atomizing nozzles fixedly connected to the bottom of the diversion pipe, and a box fixedly connected to one side of the desulfurization tower body; A gathering mechanism, which is fixedly mounted on the housing, is capable of gathering flue gas by generating swirling airflow. A swing mechanism is fixedly mounted on the vortex mechanism.

[0007] Preferably, the gathering mechanism includes a motor fixedly installed on one side of the housing, the output end of the motor extending into the interior of the housing and fixedly connected to a first pulley, the bottom of the first pulley being connected to a second pulley via a belt drive, a rotating rod fixedly connected to one side of the second pulley, one end of the rotating rod extending into the interior of the desulfurization tower body, and four arc-shaped fan blades fixedly connected to the surface of the rotating rod.

[0008] Preferably, the swing mechanism includes a missing gear fixedly connected to one side of the first pulley. A transmission gear is provided on the top of the missing gear. One side of the transmission gear is rotatably connected to the inner wall of the housing via a rotating shaft. A traction rod is fixedly connected to the other side of the missing gear. One end of the traction rod penetrates into the interior of the desulfurization tower body and is fixedly connected to one end of the diversion pipe. A torsion spring is sleeved on the surface of the traction rod. One end of the torsion spring is fixedly connected to one side of the desulfurization tower body, and the other end of the torsion spring is fixedly connected to one side of the transmission gear.

[0009] Preferably, a sealing ring is fixedly connected to the surface of the diversion pipe, and the outer surface of the sealing ring is in contact with the inner wall of the main pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up a gathering mechanism, enables the motor to be started, which drives the first pulley to rotate. The first pulley drives the second pulley to rotate via a belt. The second pulley drives the rotating rod and four arc-shaped fan blades to rotate around the bearing seat. During the rotation of the arc-shaped fan blades, a swirling airflow is generated. When the flue gas enters the desulfurization tower body, the swirling airflow gathers the flue gas in the central part. At the same time, the water pump draws water from the water tank, which is then sprayed onto the flue gas through the main pipe and the branch pipe, and finally from the atomizing nozzle, thereby improving the desulfurization effect. 2. This utility model, by setting up a swing mechanism, can drive the missing gear to rotate simultaneously with the rotation of the first pulley. When the toothed segment of the missing gear rotates to contact the transmission gear, it drives the transmission gear to rotate 180° around the axis. Then, when the missing gear rotates to the point where it no longer contacts the transmission gear, the torque generated by the torsion spring will drive the missing gear to rotate in the opposite direction and reset. This cycle repeats, and the transmission gear will drive the traction rod, the diverter pipe, and the atomizing nozzle to swing back and forth. By continuously swinging, the spray angle is changed, thereby improving the desulfurization effect. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1- Figure 5 As shown, Example 1: A calcium hydroxide desulfurization treatment device includes a desulfurization tower body 1, a water tank 2 fixedly connected to one side of the desulfurization tower body 1, a water pump 3 fixedly installed on the top of the water tank 2, a main pipe 4 fixedly connected to the outlet of the water pump 3, a diversion pipe 5 provided inside the desulfurization tower body 1, one end of the diversion pipe 5 penetrating into the interior of the main pipe 4, a plurality of atomizing nozzles 6 fixedly connected to the bottom of the diversion pipe 5, and a box body 7 fixedly connected to one side of the desulfurization tower body 1. The gathering mechanism is fixedly installed on the housing 7 and can gather the flue gas by generating swirling air. The oscillating mechanism is fixedly mounted on the vortex mechanism.

[0017] The gathering mechanism includes a motor 8 fixedly installed on one side of the housing 7. The output end of the motor 8 extends into the interior of the housing 7 and is fixedly connected to a first pulley 9. The bottom of the first pulley 9 is connected to a second pulley 10 via a belt drive. A rotating rod 11 is fixedly connected to one side of the second pulley 10. One end of the rotating rod 11 extends into the interior of the desulfurization tower body 1. Four arc-shaped fan blades 12 are fixedly connected to the surface of the rotating rod 11.

[0018] In this embodiment, considering that spray blind spots can easily exist during the desulfurization process, causing the sprayed water flow to not fully contact the flue gas, thus affecting the desulfurization effect, a gathering mechanism is set up. By starting the motor 8, the motor 8 will drive the first pulley 9 to rotate. The first pulley 9 will drive the second pulley 10 to rotate via a belt. The second pulley 10 will drive the rotating rod 11 and four arc-shaped fan blades 12 to rotate around the bearing seat 18. During the rotation of the arc-shaped fan blades 12, a swirling airflow will be generated. When the flue gas enters the desulfurization tower body 1, the swirling airflow will gather the flue gas in the central part. At the same time, the water pump 3 will draw water from the water tank 2, and after passing through the main pipe 4 and the diversion pipe 5, it will finally be sprayed onto the flue gas from the atomizing nozzle 6, thereby improving the desulfurization effect.

[0019] One end of the rotating rod 11 is provided with a bearing seat 18, and is rotatably connected to the inner wall of the desulfurization tower body 1 through the bearing seat 18.

[0020] In this embodiment, by setting the bearing seat 18, the rotating rod 11 and the arc-shaped fan blade 12 and other structures can be supported, thereby improving their stability and smoothness during rotation.

[0021] A guide groove 19 is provided on one side of the arc-shaped fan blade 12, and the number of guide grooves 19 is several.

[0022] In this embodiment, by setting the guide groove 19, the resistance encountered by the arc-shaped fan blade 12 during rotation can be reduced, and the smoothness of its rotation can be improved.

[0023] Example 2: Based on Embodiment 1, the gathering mechanism in this embodiment can gather flue gas and improve the effect of spray desulfurization. However, considering that there will still be blind spots in the spraying process due to the spraying angle, the swing mechanism in this application includes a missing gear 13 fixedly connected to one side of the first pulley 9. A transmission gear 14 is provided on the top of the missing gear 13. One side of the transmission gear 14 is rotatably connected to the inner wall of the housing 7 through a rotating shaft. A traction rod 15 is fixedly connected to the other side of the missing gear 13. One end of the traction rod 15 penetrates into the interior of the desulfurization tower body 1 and is fixedly connected to one end of the diversion pipe 5. A torsion spring 16 is sleeved on the surface of the traction rod 15. One end of the torsion spring 16 is fixedly connected to one side of the desulfurization tower body 1, and the other end of the torsion spring 16 is fixedly connected to one side of the transmission gear 14. A bearing seat 18 is provided at one end of the rotating rod 11 and is rotatably connected to the inner wall of the desulfurization tower body 1 through the bearing seat 18.

[0024] In this embodiment, by setting up a swing mechanism, when the first pulley 9 rotates, it drives the missing gear 13 to rotate. When the toothed segment of the missing gear 13 rotates to contact the transmission gear 14, it drives the transmission gear 14 to rotate 180° around the axis. Then, when the missing gear 13 rotates to the point where it is no longer in contact with the transmission gear 14, the torque generated by the torsion spring 16 will drive the missing gear 13 to rotate in the opposite direction to reset. This cycle repeats, and the transmission gear 14 will drive the traction rod 15, the diverter pipe 5, and the atomizing nozzle 6 to swing back and forth. By continuously swinging, the spray angle is changed, thereby improving the desulfurization effect.

[0025] A sealing ring 17 is fixedly connected to the surface of the diversion pipe 5, and the outer surface of the sealing ring 17 is in contact with the inner wall of the main pipe 4.

[0026] In this embodiment, by setting a sealing ring 17, the sealing performance of the connection between the diversion pipe 5 and the main pipe 4 can be improved, thus preventing leakage.

[0027] Working principle: The user starts the motor 8, which drives the first pulley 9 to rotate. The first pulley 9 drives the second pulley 10 to rotate via a belt. The second pulley 10 drives the rotating rod 11 and four arc-shaped fan blades 12 to rotate around the bearing seat 18. During the rotation of the arc-shaped fan blades 12, a swirling airflow is generated. When the flue gas enters the desulfurization tower body 1, the swirling airflow gathers the flue gas in the central part. At the same time, the water pump 3 draws water from the water tank 2, which is then sprayed onto the flue gas through the main pipe 4 and the branch pipe 5, and finally sprayed onto the flue gas through the atomizing nozzle 6, thereby improving the desulfurization effect. As the first pulley 9 rotates, it drives the missing gear 13 to rotate. When the toothed section of the missing gear 13 rotates to contact the transmission gear 14, it drives the transmission gear 14 to rotate 180° around the axis. Then, when the missing gear 13 rotates to the point where it is no longer in contact with the transmission gear 14, the torque generated by the torsion spring 16 will drive the missing gear 13 to rotate in the opposite direction to reset. This cycle repeats. The transmission gear 14 will drive the traction rod 15, the diverter pipe 5, and the atomizing nozzle 6 to swing back and forth. By continuously swinging, the spray angle is changed, thereby improving the desulfurization effect.

[0028] It should be noted that the water pump 3 and the motor 8 are existing devices or equipment, or devices or equipment that can be implemented by existing technology, and the specific composition and principle of the power supply of the water pump 3 and the motor 8 are clear to those skilled in the art, so they will not be described in detail here.
