Description

Technical Field

[0001] This utility model relates to the field of industrial waste gas purification technology, and in particular to an industrial waste gas purification device based on purification adsorption treatment. Background Technology

[0002] In industrial waste gas purification, the waste gas needs to be adsorbed by an adsorption layer. However, traditional adsorption devices mostly adopt a fixed adsorption layer structure, in which the waste gas is purified by a fixed filling of adsorption material. However, such devices have many drawbacks in actual operation, such as uneven adsorption, local adsorption saturation, and rapid decline in purification efficiency. To address these issues, we propose an industrial waste gas purification device based on adsorption purification. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an industrial waste gas purification and treatment device based on purification adsorption.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An industrial waste gas purification device based on adsorption treatment includes a second filter tank, a first adsorption layer installed inside the second filter tank, a second conical conveying hood installed at one end of the second filter tank, a connecting pipe connected to one end of the second conical conveying hood, a first filter tank connected to one end of the connecting pipe, a second adsorption layer installed inside the first filter tank, a rotating device installed on one side of the first filter tank, one end of the rotating device connected to one side of the second adsorption layer, an output structure connected to one side of the first filter tank, and multiple sensors installed on the circumferential sidewalls of the first and second filter tanks.

[0005] Preferably, the output structure includes three fixed pipes connected to one side of the first filter tank, one end of the three fixed pipes being connected to a connecting box, and one side of the connecting box being connected to an output pipe.

[0006] Preferably, the rotating device includes a speed reducer installed on one side of the first filter tank, a drive motor connected to one side of the speed reducer, a connecting rod connected to one end of the speed reducer, and one end of the connecting rod penetrating the side wall of the first filter tank and connected to one side of the second adsorption layer.

[0007] Preferably, a spiral guide plate is installed on one circumferential sidewall inside the first conical conveying hood.

[0008] Preferably, an electric valve is installed on the connecting pipe.

[0009] Preferably, one end of the second filter can is connected to an inlet pipe.

[0010] In this invention, during adsorption: 1. Waste gas introduction stage: Industrial waste gas enters the second filter tank through the input pipe and undergoes preliminary adsorption treatment through the fixed first adsorption layer. 2. Airflow acceleration and guidance stage: The pre-purified exhaust gas enters the connecting pipe through the second conical conveying hood. Under the regulation of the conical structure and electric valve, the gas flow rate is increased and uniformly distributed through the spiral guide plate in the first conical conveying hood. 3. Dynamic adsorption stage: After the exhaust gas enters the first filter tank, it comes into contact with the rotating second adsorption layer. The drive motor drives the second adsorption layer to rotate through the reducer and connecting rod, so that the adsorption material can fully contact the exhaust gas, avoid the occurrence of adsorption "dead zone", and improve adsorption efficiency. 4. Intelligent control stage: Multiple sensors installed on the inner walls of the first and second filter tanks monitor the working status of the adsorption layer in real time and feed the data back to the control system. When a certain area is close to saturation, the system automatically adjusts the motor operating parameters and controls the rotation speed of the adsorption layer. 5. Exhaust gas output stage: The exhaust gas that has completed the secondary adsorption treatment is connected to the connection box through three fixed pipes, and finally enters the subsequent treatment system or is directly discharged through the output pipe.

[0011] This utility model has the following advantages: 1. The rotating adsorption layer, combined with the fixed adsorption layer, achieves an alternating layout of dynamic and static adsorption, which greatly improves the uniformity and efficiency of adsorption. 2. The spiral guide plate effectively improves the airflow distribution, avoids local airflow concentration, and improves the utilization rate of the adsorption material; 3. The dynamic adsorption structure effectively delays the problem of local saturation of the adsorption layer, extends the maintenance cycle by up to 50%, and significantly reduces operating costs; 4. Through dynamic adsorption and structural optimization, the purification efficiency of VOCs can reach over 95%, far exceeding the 80%-85% of traditional solutions; In summary, this invention achieves an alternating layout of dynamic and static adsorption by combining a rotating adsorption layer with a fixed adsorption layer, which significantly improves adsorption uniformity and efficiency, effectively improves airflow distribution, avoids local airflow concentration, increases the utilization rate of adsorption materials, extends the maintenance cycle by up to 50%, and significantly reduces operating costs.

[0015] Reference Figure 1-5 An industrial waste gas purification and treatment device based on purification and adsorption treatment includes a second filter tank 11, and a first adsorption layer 13 is installed in the second filter tank 11. The adsorption material of the first adsorption layer 13 is selected from high specific surface area materials such as activated carbon, molecular sieve or modified ceramics. It not only plays a physical adsorption role, but can also preset chemical adsorption function according to the type of waste gas, such as adding an acid-base neutralization layer to treat sulfur-containing and nitrogen-containing waste gas, and realize multi-functional pretreatment. A second conical conveying hood 10 is installed at one end of the second filter tank 11. A connecting pipe 8 is connected to one end of the second conical conveying hood 10. A first conical conveying hood 7 is connected to one end of the connecting pipe 8. A first filter tank 6 is connected to one end of the first conical conveying hood 7. A second adsorption layer 17 is provided inside the first filter tank 6. The rotatable second adsorption layer 17 can dynamically adsorb and break the "dead zone" problem of traditional static adsorption, improve the contact area and time between the adsorption material and the waste gas, and is suitable for the treatment of high-concentration and unevenly distributed waste gas. A rotating device is installed on one side of the first filter tank 6. One end of the rotating device is connected to one side of the second adsorption layer 17. An output structure is connected to one side of the first filter tank 6. Multiple sensors 15 are installed on the circumferential sidewalls of the first filter tank 6 and the second filter tank 11. The sensors 15 monitor parameters such as temperature, humidity, pressure and adsorption saturation of the adsorption layer in real time. The data is fed back to the central control system. When a certain area is close to saturation, the system automatically adjusts the motor speed or switches the working area of ​​the adsorption layer and sets an early warning mechanism to remind the user to replace or regenerate the adsorption material. The output structure includes three fixed pipes 3 connected to one side of the first filter tank 6. One end of the three fixed pipes 3 is connected to a connecting box 2. One side of the connecting box 2 is connected to the output pipe 1. The multi-pipe parallel design can reduce pressure loss, and the connecting box plays a role in buffering and stabilizing the flow.

A spiral guide plate 14 is installed on the inner side wall of the first conical conveying hood 7. The spiral guide plate 14 makes the airflow distribution more uniform, avoids airflow short-circuiting or local turbulence, and improves adsorption efficiency. An electric valve 9 is installed on the connecting pipe 8. The electric valve 9 is linked with the intelligent control system and adjusts the opening degree in real time according to the exhaust gas concentration to achieve energy-saving operation. In addition, temperature and pressure sensors are installed inside the connecting pipe to prevent system overload or blockage. The second filter tank 11 is connected to an inlet pipe 12 at one end, and its purification efficiency for VOCs can reach more than 95%, which is much higher than the 80%-85% of the traditional solution.

[0016] In this invention, during adsorption: 1. Waste gas introduction stage: Industrial waste gas enters the second filter tank 11 through the input pipe 12, and first undergoes preliminary adsorption treatment through the fixed first adsorption layer 13; 2. Airflow acceleration and guidance stage: The pre-purified exhaust gas enters the connecting pipe 8 through the second conical conveying hood 10. Under the regulation of the conical structure and the electric valve 9, the gas flow rate is increased and uniformly distributed through the spiral guide plate 14 in the first conical conveying hood 7. 3. Dynamic adsorption stage: After the exhaust gas enters the first filter tank 6, it comes into contact with the rotating second adsorption layer 17. The drive motor 4 drives the second adsorption layer 17 to rotate through the reducer 5 and the connecting rod 16, so that the adsorption material can fully contact the exhaust gas, avoid the occurrence of adsorption "dead zone", and improve adsorption efficiency. 4. Intelligent control stage: Multiple sensors 15 installed on the inner walls of the first and second filter tanks monitor the working status of the adsorption layer in real time and feed the data back to the control system. When a certain area is close to saturation, the system automatically adjusts the motor operating parameters and controls the rotation speed of the adsorption layer. 5. Exhaust gas output stage: The exhaust gas that has completed the secondary adsorption treatment is fed into the connection box 2 through three fixed pipes 3, and finally enters the subsequent treatment system or is directly discharged through the output pipe 1.
