[0029] See Figure 1 The dosing device 100 provided in one embodiment of this application can be used in an exhaust gas treatment device 210, which is used to treat process exhaust gas generated during tobacco processing. The dosing device 100 adds alkaline agents to the exhaust gas treatment device 210 to neutralize acidic substances in the process exhaust gas. The exhaust gas treatment device 210 may include a fan, a pre-washing tank, and a convection washing tank (spray tower) to achieve multi-stage water washing, spraying, and alkaline washing, wherein alkaline washing is performed at the spray tower. In addition to the spray tower, alkaline agents can also be added to the pre-washing tank; that is, the dosing device 100 can specifically add alkaline agents to the spray tower and the pre-washing tank to adjust the pH of their internal circulating water.

[0030] The dosing device 100 includes a dosing assembly, which includes a dosing tank 10, a stirring mechanism 20, and a dosing pump 30. The dosing tank 10 has a storage chamber 11 for storing alkaline chemicals. The stirring mechanism 20 is located in the dosing tank 10 and configured to stir the alkaline chemicals in the storage chamber 11. The dosing pump 30 has an inlet and an outlet. The inlet is configured to communicate with the storage chamber 11, and the outlet is configured to communicate with the waste gas treatment equipment 210.

[0031] Understandably, the dosing assembly may also include a dosing pipe 40, with a first end connected to the dosing tank 10 and a second end configured to connect to the exhaust gas treatment equipment 210. A dosing pump 30 is located on the dosing pipe 40, i.e., its inlet and outlet are connected to the dosing pipe 40, and is configured to pump alkaline agents from the first end to the second end of the dosing pipe 40.

[0032] The alkaline agent can be an alkaline solution with a pH value greater than 7.0, and specifically, but not limited to, an aqueous solution of sodium carbonate (Na₂CO₃) with a mass concentration of 10%-15%. In other embodiments, the alkaline agent can also be an aqueous solution of sodium bicarbonate, an aqueous solution of sodium hydroxide, ammonia, etc. Understandably, to achieve its normal function, the dosing tank 10 and the dosing pipe 40 need to be made of corrosion-resistant materials to at least prevent corrosion from the alkaline agent.

[0033] The stirring mechanism 20 may include a driver 21 and a stirring element 23. The driver 21 may be located on the top of the dosing tank 10. The stirring element 23 is connected to the driver 21 and extends into the storage chamber 11 of the dosing tank 10 so as to stir the alkaline agent in the storage chamber 11 under the drive of the driver 21.

[0034] The aforementioned dosing device 100 has a dosing tank 10 capable of storing alkaline reagents, which are then pumped to the waste gas treatment equipment 210 by a dosing pump 30. This alkaline reagent neutralizes the acidic gases to be treated in the waste gas treatment equipment 210, thus improving the equipment's ability to treat process waste gases. Furthermore, the stirring mechanism 20 stirs the alkaline reagents in the storage chamber 11, which facilitates the dissolution of the solutes and maintains uniform concentration.

[0035] In some embodiments, the maximum vertical dimension of the dosing tank 10 is smaller than its maximum horizontal dimension.

[0036] Understandably, the dosing tank 10 has a horizontal structure, and its height is less than the maximum dimension in the horizontal direction. Taking the cross-section of the dosing tank 10 as a circle as an example, the height of the dosing tank 10 is less than its diameter.

[0037] Thus, the lower height of the dosing tank 10 facilitates pipe connections and helps to make the concentration of alkaline agents inside more uniform, reducing the concentration gradient in the vertical direction.

[0038] In some embodiments, the dosing pump 30 is a metering pump.

[0039] A metering pump, also known as a quantitative pump or proportional pump, is a type of positive displacement pump that can achieve precise flow control by adjusting the stroke or frequency, thus enabling constant flow pumping.

[0040] Thus, the dosing device 100 can pump alkaline agents to the waste gas treatment equipment 210 at the required flow rate by controlling the dosing pump 30.

[0041] In some embodiments, the dosing device 100 includes at least two dosing pumps 30, all of which are configured to connect to different waste gas treatment devices 210.

[0042] Understandably, the dosing device 100 includes at least two dosing pipes 40, all of which are connected in parallel and used to connect different waste gas treatment devices 210, and each dosing pipe 40 is equipped with a dosing pump 30.

[0043] In this way, the dosing device 100 can simultaneously deliver alkaline agents to multiple waste gas treatment devices 210.

[0044] In one specific embodiment, the dosing tank 10 has a capacity of 2000L, and the metering pump 30 has a maximum flow rate of 310L / h. Two metering pumps can be used. The capacity of the dosing tank 10 is sufficient to meet the needs, and the metering pump can adjust its flow rate as needed to meet the requirements of the waste gas treatment equipment 210.

[0045] In some embodiments, the dosing device 100 further includes a control component for acquiring monitoring data from the monitoring component and controlling the operation of the dosing pump 30 and the stirring mechanism 20 based on the monitoring data. The control component includes a controller 50, which is electrically connected to the dosing pump 30 and the stirring mechanism 20.

[0046] The controller 50 is a programmable logic controller, and the control components may also include a PLC control cabinet, in which the controller 50 is integrated.

[0047] Understandably, the controller 50 is used to control the operation of the dosing pump 30 and the mixing mechanism 20, including but not limited to controlling the start and stop of the dosing pump 30, controlling the pumping flow rate of the dosing pump 30, controlling the start and stop of the mixing mechanism 20, and controlling the operating cycle of the mixing mechanism 20.

[0048] In this way, the user can better control the automatic operation of the dosing pump 30 and the stirring mechanism 20 through the controller 50.

[0049] In some embodiments, the dosing device 100 further includes an alarm that is electrically connected to the controller 50.

[0050] Understandably, an alarm device can emit an alarm signal, which can be, but is not limited to, audible and visual signals. The controller 50 can control the alarm device to emit an alarm signal when the equipment experiences abnormal operating conditions.

[0051] In this way, users can promptly detect faults and carry out relevant troubleshooting and repair work to ensure the stable operation of the dosing device 100 and the waste gas treatment equipment 210.

[0052] In some embodiments, the dosing device 100 further includes a monitoring component, which includes a level detection element 70 disposed in the dosing tank 10 and electrically connected to the controller 50, and configured to detect the level of alkaline agent in the storage chamber 11.

[0053] Understandably, the controller 50 is capable of accepting and processing the detection results of the liquid level detection device 70. Based on the detection results of the liquid level detection device 70, the controller 50 can set up liquid level interlock protection for the dosing tank 10. For example, when the liquid level is lower than 0.2m, the controller 50 stops the dosing pump 30 and triggers an alarm.

[0054] Thus, the detection result of the liquid level detection device 70 can reflect the liquid level in the dosing tank 10. Based on this, the controller 50 can correspondingly control the dosing pump 30 to stop delivering the drug in preparation for replenishing the alkaline agent in the dosing tank 10.

[0055] In some embodiments, the monitoring component further includes a first acid-base meter 60, which is disposed in the dosing tank 10 and electrically connected to the controller 50, and is configured to detect the acidity or alkalinity of the alkaline agent in the storage chamber 11.

[0056] Understandably, the first acid-base meter 60 is a pH meter, and the controller 50 can accept and process the detection results of the first acid-base meter 60. The detection results of the first acid-base meter 60 can reflect the acidity or alkalinity of the alkaline agent in the storage chamber 11 of the dosing tank 10.

[0057] Thus, the first acid-base meter 60 helps to determine the acidity or alkalinity of alkaline reagents to judge whether they meet the usage standards. Based on the detection results of the first acid-base meter 60, the controller 50 can correspondingly control the start and stop of the dosing pump 30, the stirring mechanism 20, etc.

[0058] In some embodiments, the monitoring component further includes a second acid-base meter, which is electrically connected to the controller 50 and configured to detect the acidity or alkalinity of the circulating water within the exhaust gas treatment device 210.

[0059] Understandably, the second acid-base meter is a pH meter, and the controller 50 can accept and process the detection results of the second acid-base meter. The detection results of the second acid-base meter can reflect the acidity or alkalinity of the circulating water in the waste gas treatment equipment 210.

[0060] Thus, the second pH meter helps to determine the pH of the circulating water within the reaction waste gas treatment equipment 210, in order to assess the effect of the alkaline reagent on its adjustment. Based on the detection results of the second pH meter, the controller 50 can correspondingly control the start / stop and flow rate of the dosing pump 30 to maintain the pH of the circulating water within the reaction waste gas treatment equipment 210 within the target range, for example, a pH value within the range of 6.5-7.0.

[0061] In some embodiments, the monitoring component further includes a display electrically connected to the controller 50.

[0062] Understandably, the display can be used to show key parameters such as the operating status of the dosing pump 30, the working status of the stirring mechanism 20, the liquid level of the dosing tank 10, and the pH value in the spray tower, or fault codes.

[0063] In this way, the display can show relevant parameters and fault codes, allowing users to understand the operating status of the dosing device 100 and the waste gas treatment equipment 210.

[0064] The aforementioned dosing device 100 includes a dosing component, a control component, and a monitoring component. The dosing component includes a 2000L dosing tank 10, two metering pumps with a flow rate of 310L / h, a stirring mechanism 20, and a corrosion-resistant dosing pipe 40, which connects to the spray tower for precise dosing of alkaline agents. The control component includes a PLC control cabinet with an integrated controller 50 and a human-machine interface, supporting automatic / manual control mode switching and providing parameter setting, status monitoring, and safety protection functions. The monitoring component includes an online pH meter (serving as a first and second pH meter 60) and a level sensor (serving as a level detection element 70), enabling real-time monitoring of the pH value in the dosing tank 10, the pH value in the spray tower, and the level in the dosing tank 10. The control component uses a PID control algorithm to adjust the output flow rate of the metering pumps based on the feedback signal from the online pH meter, maintaining the pH value of the circulating water in the spray tower within the range of 6.5-7.0. The dosing tank 10 is equipped with a liquid level interlock protection. When the liquid level is below 0.2m, the controller 50 stops the metering pump and triggers an alarm. The alkaline agent is a sodium carbonate (Na2CO3) aqueous solution with a mass concentration of 10%-15%, and the dosing is continuously adjustable within the range of 0-310L / h via the metering pump.

[0065] The installation and operation of the dosing device 100 are briefly described below:

[0066] 1. Equipment Installation and Commissioning: Install the dosing tank 10 near the spray tower and connect the dosing pipe 40 to the spray tower's circulating water inlet; install a second pH meter on the spray tower's circulating water pipe and a level sensor inside the dosing tank 10; connect the metering pump, control cabinet, and other electrical equipment to the power supply and complete the pipeline system's airtightness test; set the initial parameters through the control cabinet's HMI: pH lower limit 6.5, upper limit 7.0, and dosing tank 10 level interlock protection value 0.2m.

[0067] 2. Automatic Operation Mode: Select the automatic operation mode on the control cabinet HMI, and start the stirring mechanism 20 to premix the sodium carbonate solution in the dosing tank 10; when the pH value in the spray tower is lower than 6.5, the control component automatically starts the metering pump and adds the agent at the preset flow rate (200L / h); as the agent is added, the pH value of the circulating water gradually increases, and when it reaches 7.0, the control component stops the metering pump; when the liquid level in the dosing tank 10 drops to 0.2m, the control component triggers a low liquid level alarm and stops all dosing operations.

[0068] 3. Manual maintenance operation: By switching the HMI in the control cabinet to manual mode, the metering pump and stirring mechanism 20 can be started / stopped respectively; the equipment operation record can be viewed through the HMI regularly, including information such as dosage, running time, and fault codes; when the pH meter measurement is abnormal, the calibration program can be started through the HMI to perform three-point calibration using standard buffer solution.

[0069] Specifically, the control components include a central control unit, a parameter setting module, a mode switching module, a status monitoring module, and a safety protection module. The central control unit is a control cabinet built using a programmable logic controller (PLC) and integrates a human-machine interface (HMI). The parameter setting module, via the HMI, allows setting process parameters such as the start / stop threshold of the dosing pump 30, the level interlock protection value of the dosing tank 10, and the operating cycle of the stirring mechanism 20. The mode switching module enables the control components to switch between automatic and manual operation modes. The status monitoring module displays key parameters in real time on a monitor, including the operating status of the dosing pump 30, the working status of the stirring mechanism 20, the level of the dosing tank 10, and the pH value in the spray tower. The safety protection module has a self-diagnostic function; when abnormal operating conditions occur, it triggers an alarm with audible and visual alarms and displays a fault code. The monitoring components include a pH monitoring unit and a level monitoring unit. The pH monitoring unit includes a first pH meter 60 and a second pH meter. The second pH meter is installed on the circulating water pipeline of the spray tower to monitor the pH value of the circulating water in real time. The liquid level monitoring unit includes a liquid level sensor, which is installed inside the dosing tank 10 to achieve continuous monitoring of the liquid level.

[0070] Thus, the dosing device 100 has the following advantages:

[0071] 1. Precise dosing control: Through online pH monitoring and PID control algorithm, the dosage can be precisely adjusted, improving the utilization rate of the agent by more than 30%.

[0072] 2. Fully automated operation: PLC control enables 24-hour unattended operation, reducing the need for manual intervention by 80%.

[0073] 3. Multiple safety protections: Equipped with multiple safety mechanisms such as liquid level interlock, overload protection, and fault alarm, the equipment's operational reliability reaches 99.5%.

[0074] 4. Significant environmental benefits: According to verification by a third-party testing agency, the odor concentration in the exhaust stack decreased by 58% after the device was put into operation, meeting the requirements of the "Odor Pollutant Emission Standard" (GB 14554-93).

[0075] 5. Economic advantages: Using sodium carbonate as the neutralizing agent reduces the agent cost by 25% compared to the traditional sodium hydroxide solution, resulting in annual operating cost savings of approximately 120,000 yuan.

[0076] This application also provides an exhaust gas treatment system 200, including an exhaust gas treatment device 210 and the above-mentioned dosing device 100.

[0077] The dosing device 100 is used to add alkaline agents to the waste gas treatment equipment 210 to neutralize acidic substances in the process waste gas. Specifically, the outlet of the dosing pump 30 is connected to the waste gas treatment equipment 210. The waste gas treatment equipment 210 may include a fan, a pre-wash tank, and a convection washing tank (spray tower) to achieve multi-stage water washing, spraying, and alkaline washing, wherein the alkaline washing is carried out at the spray tower. In addition to the spray tower, alkaline agents may also be added to the pre-wash tank, that is, the dosing device 100 can specifically add alkaline agents to both the spray tower and the pre-wash tank.

[0078] The exhaust gas treatment system 200 may include multiple exhaust gas treatment devices 210, and the dosing device 100 includes multiple dosing pumps 30, with different dosing pumps 30 connected to different exhaust gas treatment devices 210 to pump alkaline agents to each exhaust gas treatment device 210.

[0079] The aforementioned waste gas treatment system 200 is used for waste gas treatment in the tobacco industry. This system achieves precise dosing of alkaline agents through automated control components, effectively neutralizing acidic components in the tobacco processing waste gas, reducing odor concentration, and improving environmental quality. The dosing tank 10 of the dosing device 100 adopts a horizontal structure design, which helps to reduce equipment height, facilitates installation and maintenance, and optimizes energy consumption management, resulting in significant environmental and economic benefits.

[0080] 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.

[0081] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
