Description

Technical Field

[0001] This utility model belongs to the field of flue gas purification and treatment, and in particular relates to a tobacco odor treatment and neutralization reaction spray tower system. Background Technology

[0002] As tobacco processing and production proceed, the curing and drying stages of tobacco leaves release gases containing aldehydes, ketones, nicotine, and other compounds. These gases not only have a pungent odor but also contain a certain amount of harmful substances. If directly released into the atmosphere from production equipment, they will impact the air quality of the surrounding environment. Against this backdrop, purifying these tobacco-odor-containing gases has become a crucial step in achieving green production in the tobacco industry.

[0003] Currently, the common treatment method involves using a fan to introduce gases containing tobacco odor into a spray tower, where the spray liquid comes into contact with the gas, removing pollutants through absorption, neutralization, and other chemical reactions. However, most existing spray towers are simple straight-through structures with relatively high gas flow rates and short residence times within the tower, resulting in insufficient contact with the spray liquid. This leads to incomplete neutralization reactions, unsatisfactory purification effects, and difficulty in consistently meeting emission standards.

[0004] Therefore, there is a particular need for a tobacco odor treatment and neutralization reaction spray tower system to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing spray towers, which have a straight-through structure, short gas residence time, insufficient contact with spray liquid, and unsatisfactory purification effect, this utility model provides a tobacco odor treatment neutralization reaction spray tower system.

[0006] This utility model is achieved through the following technical means: a tobacco odor treatment and neutralization reaction spray tower system, including a support base, a spray tower body, an air inlet pipe, a filter plate, a drain pipe, a valve, a fan, an air outlet pipe, a support frame, a storage tank, a first drain pipe, a second drain pipe, a solenoid valve, a pump, connecting pipes, and spray nozzles. The support base is installed at the bottom of the spray tower body, the air inlet pipe is fixed to the lower part of the spray tower body, the filter plate is fixed to the lower part of the spray tower body, the air inlet pipe is positioned lower than the filter plate, the drain pipe is fixed to the bottom of the spray tower body and connects to the interior of the spray tower body, the drain pipe passes through the support base and extends to its exterior, the valve is installed on the drain pipe, and the fan is installed on the spray tower. The upper part of the main body has an exhaust pipe fixed to the rear of the fan. The support frame is installed on the outside of the spray tower body. The liquid storage tank is installed on the rear of the support frame. Inlet pipe one and inlet pipe two are symmetrically distributed and fixed to the upper part of the liquid storage tank. Solenoid valves are installed on both inlet pipe one and inlet pipe two. The liquid pump is installed at the bottom of the liquid storage tank. The liquid pump's pumping end is connected to the inside of the liquid storage tank. The connecting pipe is fixed to the liquid pump's outlet end. The annular section of the connecting pipe is located at a high point inside the spray tower body. Multiple evenly distributed nozzles are fixed on the annular section. The system also includes an installation ring and diffuser balls. The installation ring is also installed at a low point inside the spray tower body. Multiple neatly distributed diffuser balls are rotatably arranged inside the installation ring.

[0007] Optionally, it also includes a servo motor and a stirring paddle. The servo motor is mounted on the top of the liquid storage tank, and the output shaft of the servo motor passes through the liquid storage tank and extends into its interior. The stirring paddle is fixed to the output shaft of the servo motor and is located inside the liquid storage tank.

[0008] Optionally, it also includes a detector, a detection rod, and a control module. The detector is installed on the upper part of the liquid storage tank, and the detection rod at the lower part of the detector penetrates into the interior of the liquid storage tank, with the end of the detection rod close to the lowest point inside the liquid storage tank. The control module is installed at the front of the spray tower body, and the detector and the two solenoid valves are electrically connected to the control module.

[0009] Optionally, it also includes a transparent plate, which is embedded and fixed to the rear of the liquid storage tank.

[0010] Optionally, the filter plate has a multi-layer composite structure, consisting of a coarse filter layer and a fine filter layer stacked together, with a gradient distribution of pore size.

[0011] Optionally, the two ends of the agitator are respectively close to the highest and lowest liquid level lines inside the storage tank.

[0012] Beneficial effects: 1. By setting up an installation ring and multiple diffuser balls, the original straight airflow channel is transformed into a complex flow path with multi-hole penetration and multi-stage diversion. When the gas passes through the diffuser balls, it is forcibly divided into multiple fine streams and undergoes multiple micro-hole passages, which significantly prolongs the residence time of the gas in the spray tower body. At the same time, it enhances the airflow turbulence and distribution uniformity, effectively avoids short-circuit flow, and ensures that the gas and spray liquid have sufficient contact time and reaction opportunities, thereby improving purification efficiency and ensuring the consistency of treatment effect.

[0013] 2. By configuring a stirring mechanism consisting of a servo motor and a stirring paddle, the absorbent liquid in the storage tank is continuously stirred, which effectively prevents the absorbent liquid concentration from stratifying and maintains the chemical activity and reaction efficiency of the spray liquid.

[0014] 3. By setting up detectors, detection rods and control modules, the liquid level in the storage tank can be monitored continuously in real time, realizing intelligent management of constant liquid level of the absorbent and avoiding spray interruption due to lack of liquid.

[0021] Example: A tobacco odor treatment and neutralization reaction spray tower system, such as Figures 1-5As shown, the system includes a support base 1, a spray tower body 2, an air inlet pipe 3, a filter plate 4, a drain pipe 7, a valve 71, a blower 8, an air outlet pipe 9, a support frame 10, a storage tank 11, a transparent plate 12, a first inlet pipe 14, a second inlet pipe 15, a solenoid valve 151, a liquid pump 16, a connecting pipe 17, and a spray nozzle 171. The support base 1 is fixed to the bottom of the spray tower body 2 with bolts. The air inlet pipe 3 is fixedly connected to the lower left side of the spray tower body 2. The filter plate 4 is fixedly connected to the lower part of the spray tower body 2. The filter plate 4 has a multi-layer composite structure, consisting of a coarse filter layer and a fine filter layer. The filter layers are stacked with a gradient pore size distribution, effectively intercepting dust particles and impurities. The inlet pipe 3 is positioned lower than the filter plate 4. The drain pipe 7 is fixedly connected to the bottom of the spray tower body 2 and connects to the interior of the spray tower body 2. The drain pipe 7 passes through the support base 1 and extends to its exterior. A valve 71 is installed on the drain pipe 7; the valve 71 is a manually operated valve. The fan 8 is bolted to the upper part of the spray tower body 2. The outlet pipe 9 is fixedly connected to the rear left side of the fan 8. The inlet end of the inlet pipe 3 faces forward, and the outlet end of the outlet pipe 9 faces backward. The inlet pipe 3 and the outlet pipe 9 are connected... The air ducts 9 are arranged in a front-to-back orientation to optimize the airflow path. The support frame 10 is fixed to the outside of the spray tower body 2 by bolts. The liquid storage tank 11 is fixed to the annular space at the rear of the support frame 10 by bolts. A transparent plate 12 is embedded and fixedly connected to the rear of the liquid storage tank 11, allowing operators to observe the liquid level inside the liquid storage tank 11 through the transparent plate 12. Inlet pipe 14 and inlet pipe 2 15 are symmetrically distributed and fixedly connected to the upper part of the liquid storage tank 11. Solenoid valves 151 are fixed to both inlet pipe 14 and inlet pipe 2 15 by bolts. The liquid pump 16 is fixed to the... At the bottom center of the storage tank 11, the pump 16 is connected to the inside of the storage tank 11. The connecting pipe 17 is fixedly connected to the outlet of the pump 16. The annular section of the connecting pipe 17 is located at a high point inside the spray tower body 2. Multiple evenly distributed nozzles 171 are fixedly connected to the annular section. The system also includes an installation ring 5 and a diffuser ball 6. The installation ring 5 is fixed to a low point inside the spray tower body 2 by bolts. The filter plate 4 is located directly below the installation ring 5. Multiple neatly distributed diffuser balls 6 are rotatably arranged inside the installation ring 5. The diffuser ball 6 has a hollow porous structure.

[0022] like Figure 5 As shown, it also includes a servo motor 13 and a stirring paddle 131. The servo motor 13 is fixed to the top of the liquid storage tank 11 by bolts. The output shaft of the servo motor 13 extends vertically downward and passes through the liquid storage tank 11 into its interior. The stirring paddle 131 is fixedly connected to the output shaft of the servo motor 13 by a coupling. The stirring paddle 131 is located inside the liquid storage tank 11, and the upper and lower ends of the stirring paddle 131 are close to the highest liquid level line and the lowest liquid level line inside the liquid storage tank 11, respectively, to ensure that the absorbent liquid in the liquid storage tank 11 can be fully stirred and mixed.

[0023] like Figure 1 and Figure 5As shown, it also includes a detector 18, a detection rod 19, and a control module 20. The detector 18 is fixed to the upper part of the liquid storage tank 11 by bolts. The detection rod 19, which is set at the lower part of the detector 18, penetrates into the interior of the liquid storage tank 11, and the end of the detection rod 19 is close to the lowest point inside the liquid storage tank 11. The control module 20 is fixed to the middle position of the front part of the spray tower body 2 by bolts. The detector 18 and the two solenoid valves 151 are electrically connected to the control module 20.

[0024] When in use, the operator first connects the external discharge pipe to the outlet end of the drain pipe 7 and opens the valve 71 to ensure that the drain pipe 7 can discharge the waste liquid smoothly. Then, the outlet pipe of the external large-capacity liquid storage container is connected to the inlet pipe 14 and the inlet pipe 25 respectively to complete the connection of the replenishment pipeline. At this time, the two solenoid valves 151 are in the closed state, and the inlet pipe 14 and the inlet pipe 2 15 remain closed.

[0025] After the detector 18 is activated, the detection rod 19 begins to monitor the liquid level inside the storage tank 11 in real time. When the detection rod 19 senses that the liquid level is lower than the preset lower limit, it immediately transmits the signal to the control module 20. After receiving the signal, the control module 20 issues a control command to open the two solenoid valves 151 and connect the first liquid inlet pipe 14 and the second liquid inlet pipe 15. The absorbent liquid in the external large-capacity storage container flows into the storage tank under pressure through the first liquid inlet pipe 14 and the second liquid inlet pipe 15. During the replenishment process, the detection rod 19 continuously provides feedback on the liquid level change. When the liquid level rises to the preset upper limit, the control module 20 immediately closes the two solenoid valves 151 and stops replenishing the liquid, ensuring that the storage tank 11 always maintains the amount of absorbent liquid.

[0026] Then, the blower 8, the liquid pump 16, and the servo motor 13 are started. After the blower 8 starts running, a negative pressure is formed inside the spray tower body 2, which draws in the gas containing tobacco odor from the air inlet end of the air inlet pipe 3 and introduces it into the interior of the spray tower body 2. The gas first passes through the filter plate 4 to achieve preliminary physical interception of dust particles and impurities and remove suspended matter. The filtered gas continues to rise and enters the diffusion area enclosed by the installation ring 5, and comes into contact with multiple diffusion balls 6. During the flow, the gas is forced to pass through a large number of micropores distributed on the surface of the diffusion balls 6 through multiple channels. The flow path is significantly extended. At the same time, the airflow is divided into multiple fine streams, forming local turbulent disturbances, which effectively prolongs the residence time of the gas in the spray tower body 2 and prevents the gas flow rate from being too fast.

[0027] After diffusion and homogenization, the gas continues to flow upward and enters the spray zone. At this time, the liquid pump 16 draws the absorbent from the storage tank 11 and transports it to its annular pipe section through the connecting pipe 17. Finally, it is sprayed through multiple nozzles 171 to form a fine liquid curtain. The rising gas and the spray liquid form a countercurrent contact in the spray tower body 2, and a mass transfer process and neutralization chemical reaction occur. The odor components are fully absorbed, the purification efficiency is improved, and the treated clean gas is discharged from the outlet end of the outlet pipe 9.

[0028] Throughout the entire process, the servo motor 13 continuously drives the stirring paddle 131 to rotate within the storage tank 11, ensuring that the absorbent is fully mixed throughout the entire volume, effectively preventing precipitation and concentration stratification, and maintaining the chemical stability and reactivity of the spray solution.
