Abstract

The application relates to the technical field of adsorption purification devices, and discloses a volatile organic compound unit adsorption purification device which comprises a supporting table, an adsorption box, an activated carbon screen plate, a treatment box, a hollow shaft, a spraying frame and a gas conveying pipe. When used, waste gas enters the inside of the treatment tower and is adsorbed and treated by the multiple activated carbon screen plates. Then, the waste gas enters the inside of multiple treatment cavities through multiple gas conveying pipes, multiple hollow shafts and multiple spraying frames in sequence and is reacted and purified by corresponding treatment liquid in sequence. In the process of reaction and purification, the multiple hollow shafts can rotate under the driving of external force, thereby driving the multiple spraying frames to rotate. When the multiple spraying frames rotate, the treatment liquid in the multiple treatment cavities can be stirred, so that the treatment liquid and the waste gas are fully mixed. Moreover, the waste gas can be uniformly dispersed in the treatment liquid when entering the treatment liquid, so that the mixing effect of the treatment liquid and the waste gas is further improved.

[0017] The unit-type adsorption and purification device for volatile organic compounds provided in this disclosure can achieve the following technical effects: This disclosure provides a unit-type adsorption purification device for volatile organic compounds (VOCs), comprising a support platform, an adsorption box, an activated carbon mesh plate, a treatment box, a hollow shaft, a spray frame, and a gas delivery pipe. The support platform rests against the ground, thus supporting the entire device. The adsorption unit, installed on the top surface of the support platform, is used to adsorb and treat waste gas. The activated carbon mesh plate is detachably installed inside the adsorption box, distributed sequentially from top to bottom along the height of the support platform. The activated carbon mesh plate has a large adsorption area and strong adsorption capacity, used to remove odors and harmful gases. The treatment box, also installed on the top surface of the support platform, is used to purify the waste gas. The treatment box includes multiple non-communicating treatment chambers, each containing a corresponding treatment liquid, such as a nitrogen-containing organic compound treatment liquid, a sulfur-containing organic compound treatment liquid, and an oxygen-containing organic compound treatment liquid, to purify nitrogen-containing organic compounds, sulfur-containing organic compounds, and oxygen-containing organic compounds respectively. Along the length of the support platform, the adsorption box and multiple treatment chambers are distributed sequentially from left to right. Hollow shafts are rotatably mounted on the top wall of the treatment tank along the height of the support platform, extending into multiple treatment chambers and capable of rotating relative to the top wall of the treatment tank. Sprayers are mounted on the bottom ends of the hollow shafts and rotate under their influence. After the treatment tanks are filled with the corresponding treatment solutions, the sprayers are positioned inside those solutions. Gas delivery pipes are rotatably connected to the tops of the hollow shafts and are used to deliver exhaust gas.

[0030] Combination Figures 1 to 5 As shown in the figure, this disclosure provides a unit-type adsorption purification device for volatile organic compounds, including a support platform 1, an adsorption box 2, an activated carbon mesh plate 3, a treatment box 4, a hollow shaft 5, a spray frame 6, and a gas delivery pipe 7. The support platform 1 is used to support the entire device by abutting against the ground. The adsorption unit, as an adsorption unit, is installed on the top surface of the support platform 1 and is used to adsorb and treat waste gas. The activated carbon mesh plate 3 is detachably installed inside the adsorption box 2 and is distributed from top to bottom along the height direction of the support platform 1 inside the adsorption box 2. The activated carbon mesh plate 3 has a large adsorption area and strong adsorption capacity, and is used to remove odors and harmful gases. The treatment box 4, as a purification unit, is installed on the top surface of the support platform 1 and is used to purify the waste gas. The interior of the treatment box 4 includes multiple non-interconnected treatment chambers, each of which is used to contain a corresponding treatment liquid, such as a nitrogen-containing organic matter treatment liquid, a sulfur-containing organic matter treatment liquid, and an oxygen-containing organic matter treatment liquid, to purify nitrogen-containing organic matter, sulfur-containing organic matter, and oxygen-containing organic matter, respectively. Along the length of the support platform 1, the adsorption box 2 and multiple treatment chambers are distributed sequentially from left to right. Hollow shafts 5 are rotatably mounted on the top wall of the treatment box 4 along the height of the support platform 1, extending into the interiors of the multiple treatment chambers and capable of rotating relative to the top wall of the treatment box 4. Sprayers 6 are mounted on the bottom ends of the hollow shafts 5 and rotate under their influence. After the treatment boxes 4 are filled with the corresponding treatment liquid, the sprayers 6 are positioned inside the corresponding liquid. Gas delivery pipes 7 are rotatably connected to the top ends of the hollow shafts 5 and are used to deliver exhaust gas. The leftmost gas delivery pipe 7 is connected to the exhaust port of the adsorption box 2, and the remaining gas delivery pipes 7 are inserted into the adjacent treatment chambers on the left, allowing the exhaust gas to flow sequentially through the adsorption box 2 and the multiple treatment chambers. The hollow shafts 5 can be controlled to rotate, driving the sprayers 6 to rotate.

[0031] This disclosure provides a unit-type adsorption purification device for volatile organic compounds. After the waste gas enters the treatment tower, it is adsorbed and treated by multiple activated carbon mesh plates 3. Then, it sequentially enters multiple treatment chambers through multiple gas supply pipes 7, multiple hollow shafts 5, and multiple spray frames 6, where it is reacted and purified by the corresponding treatment liquids. During the reaction purification process, the multiple hollow shafts 5 rotate under external force, thereby driving the multiple spray frames 6 to rotate. When the multiple spray frames 6 rotate, they not only agitate the treatment liquids in the multiple treatment chambers, ensuring thorough mixing between the treatment liquid and the waste gas, but also uniformly disperse the waste gas in the treatment liquids as it enters them, further improving the mixing effect between the treatment liquid and the waste gas.

Any one of the hollow shafts 5 can be controlled to rotate, thereby driving the other hollow shafts 5 to rotate.

[0033] In this embodiment, once any hollow shaft 5 is controlled to rotate, it can drive the first pulley mounted on it to rotate. Through multiple first belts 8, the remaining first pulleys can be driven to rotate, thereby driving the remaining multiple hollow shafts 5 to rotate. Compared to driving multiple hollow shafts 5 to rotate separately, this reduces the number of power sources.

The motor mount 9 is mounted on the top surface of the processing box 4 to support the drive motor 10. The drive motor 10 is mounted on the motor mount 9 to provide driving force. The second pulley is mounted on the rotating end of the drive motor 10 and rotates under the drive of the drive motor 10. The second belt 11 is fitted between the second pulley and the adjacent first pulley to transmit driving force.

[0035] In this embodiment, controlling the drive motor 10 to operate will drive the second pulley to rotate. The second belt 11 will then drive the first pulley connected to it to rotate. Multiple first belts 8 will drive the remaining first pulleys to rotate, ultimately achieving the function of automatic rotation of multiple hollow shafts 5.

The bearing housings 14 are mounted on the top wall of the processing box 4 and are respectively fitted onto multiple hollow shafts 5. The bearings are respectively installed between the multiple bearing housings 14 and the multiple hollow shafts 5.

[0041] In this embodiment, multiple bearing seats 14 are installed on the top wall of the processing box 4, respectively supporting and limiting the installation of multiple bearings. The multiple bearings are used to support and install multiple hollow shafts 5, reducing the frictional force on the multiple hollow shafts 5 and improving the rotational accuracy of the multiple hollow shafts 5.

[0042] Optionally, it also includes supports 15. Supports 15 are installed on the inner wall of the adsorption box 2 and are distributed from top to bottom inside the adsorption box 2 along the height direction of the support platform 1.
