Description

Technical Field

[0001] The utility model relates to the technical field of continuous desorption of VOCs adsorbents, and more specifically, to a continuous desorption device for VOCs adsorbents. Background Art

[0002] In the existing technology, the continuous desorption device of volatile organic compounds (VOCs) adsorbent is an environmental protection equipment, which is widely used in chemical, petrochemical, printing, coating and other industries for treating and recovering VOCs emissions. In the desorption process, this device usually uses heating to desorb the VOCs on the adsorbent for subsequent treatment or recovery. However, in the heating desorption process, temperature control is crucial. Too high or too low temperature may lead to poor desorption effect or damage to the adsorbent. Therefore, it is necessary to use a temperature sensor to monitor and control the temperature in real time during the heating process.

[0003] However, existing VOCs adsorbent continuous desorption devices often have sealing problems when installing or replacing sensors. Due to the particularity of the sensor installation location and the precision of the sensor itself, it is difficult to achieve synchronous sealing when installing or replacing sensors in existing equipment. This may cause leakage during the operation of the device, affecting the treatment effect of VOCs, and may even cause the adsorbent to fail and reduce the desorption efficiency. At the same time, leakage may also threaten the safety of operators, increase the risk of equipment failure, and increase maintenance costs. Utility Model Content

The two ends of the spring 12 respectively abut on the one-way disk 9 and the limit ring 10. The two ends of the multiple rubber strips 5 are respectively provided with a moving ring 13 and a fixed ring 14. The fixed ring 14 abuts on the one-way sleeve 8. A plurality of contraction grooves 15 are provided on the side walls of the multiple rubber strips 5, and a groove 16 is provided on the inner wall of the rubber strip 5. The moving mechanism includes a push tube 17 and a fitting ring 18. The push tube 17 is slidably connected in the fixed tube 3. The fitting ring 18 is coaxially installed on the push tube 17. The fitting ring 18 abuts on the sealing sleeve 4. A thrust bearing 19 is sleeved on the sealing sleeve 4.

[0030] In this embodiment, when detecting the temperature in the corresponding desorption pipeline 1, it is necessary to install the corresponding sensor. Since a sealing sleeve 4 is installed on the sensor, the sealing sleeve 4 is then inserted into the fixed tube 3, and then the threaded sleeve 20 is threadedly connected to the fixed tube 3, so that the fitting ring 18 is in contact with the sealing sleeve 4, and the push rod 7 is pressed against the one-way disk 9. As the threaded ring rotates, the multiple rubber strips 5 fit each other and the movement of the push rod 7 releases the seal between the one-way disk 9 and the one-way sleeve 8.

[0032] More specifically, after the installation of the sensor is completed, the temperature inside the vertical tube 2 can be detected by the sensor, thereby ensuring the heating and desorption process of the adsorbent. When the sensor is replaced or one of the sensors is damaged, the corresponding sensor is taken out and replaced. When the sensor is taken out, the one-way disk 9 is attached to the one-way sleeve 8 under the action of the spring 12, so that effective sealing can be performed, thereby avoiding leakage during replacement.

[0033] In summary, when the overall equipment is in use or operation: when detecting the temperature in the corresponding desorption pipeline 1, the corresponding sensor needs to be installed. Since a sealing sleeve 4 is installed on the sensor, the sealing sleeve 4 is then inserted into the fixed tube 3, and then the threaded sleeve 20 is threadedly connected to the fixed tube 3, so that the fitting ring 18 is in contact with the sealing sleeve 4, and the push rod 7 is in contact with the one-way disk 9. As the threaded ring rotates, multiple rubber strips 5 fit each other and the movement of the push rod 7 releases the seal between the one-way disk 9 and the one-way sleeve 8, and then multiple rubber strips 5 are in contact with each other on the groove 16, so that they actually have a tendency to expand, and then the rubber strips 5 are respectively fitted between the sealing sleeve 4 and the fixed tube 3, thereby completing the sealing. While completing the sealing, the sensor body 6 and the vertical tube 2 can also be connected, and then the temperature can be measured.

[0034] After the installation of the sensor is completed, the temperature inside the vertical tube 2 can be detected by the sensor, thereby ensuring the heating and desorption process of the adsorbent. When the sensor is replaced or one of the sensors is damaged, the corresponding sensor is taken out and replaced. When the sensor is taken out, the one-way disk 9 is attached to the one-way sleeve 8 under the action of the spring 12, so that effective sealing can be performed, thereby avoiding leakage during replacement.
