Description

Technical Field

[0001] This utility model belongs to the field of utility tunnel maintenance technology, specifically a dehumidification and ventilation device for airport integrated utility tunnels. Background Technology

[0002] Airport utility tunnels are tunnel spaces designed to accommodate various pipelines, such as gas, electricity, and telecommunications lines. By incorporating dehumidification and ventilation systems, airport utility tunnels maintain a dry environment, preventing excessive humidity from shortening the lifespan of the pipelines.

[0003] However, existing dehumidification and ventilation devices for airport integrated utility tunnels typically only deliver outside air to the tunnel through ventilation shafts, thereby exhausting the air inside the tunnel. However, this method increases the humidity of the tunnel when the outside air humidity is low, which corrodes the pipes and reduces the service life of the equipment inside the tunnel. At the same time, existing ventilation devices often cause the air inlets to become blocked during use, resulting in poor ventilation and dehumidification effects. In order to solve the above problems, this utility model designs a dehumidification and ventilation device for airport integrated utility tunnels. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a dehumidification and ventilation device for airport integrated pipe corridors, which effectively solves the problems mentioned in the background art.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention uses a left-end fan that rotates forward to draw outside air into the air intake box, and a right-end fan that rotates in reverse to expel air from the pipe gallery, thus achieving circulation and ensuring airflow efficiency. At the same time, the fence prevents leaves and large debris from entering the ventilation shaft, thus preventing the fan from getting tangled and ensuring the fan's safety.

[0012] This invention uses a filter plate to filter impurities in the air, an air inlet pipe to supply the required air to the heating chamber, a heating plate to heat the air inside the heating chamber, and an exhaust fan to accelerate airflow, thereby increasing the rate of air heating and ensuring the air quality inside the heating chamber.

A water pump and solenoid valve allow the water produced by the dehumidifier to be discharged outside the equipment through the outlet pipe, ensuring the dehumidification effect. Simultaneously, a locking spring allows the locking rod to move inwards when no force is applied, thereby positioning the filter disc and ensuring its stability, thus guaranteeing the filtration effect.

[0031] When using this equipment, the staff installs the entire device according to requirements. The staff then installs the filter plate 405 and the filter disc 601. At this time, the controller 103 controls the temperature and humidity sensor 105 to operate, thereby monitoring the temperature and humidity inside the pipe gallery 1. The monitoring data can be transmitted to an external control device. When the temperature and humidity sensor 105 detects a low temperature inside the pipe gallery 1, the controller 103 controls the left-end fan 8 to rotate forward, causing the left-end fan 801 to rotate forward. This draws outside air into the air inlet box 4 through the grille 201, and then through the filter plate 405 to the air inlet pipe 403, and finally blown to the heating element. Inside chamber 5, the controller 103 controls the heater 501 to heat the air inside the heating chamber 5 via the heating plate 503. Furthermore, the controller 103 controls the exhaust fan 504 to rotate, thereby driving the exhaust fan 505 to discharge the heated air inside the heating chamber 5 through the exhaust plate 502. Simultaneously, the controller 103 controls the right-end fan 8 to reverse, causing the right-end fan 801 to rotate in reverse, thus discharging the low-temperature gas inside the pipe gallery 1 through the right-end grille 201. When the inlet flow meter 402 detects a small airflow rate entering the inlet pipe 403, the controller 103 determines that the airflow is too low. When filter plate 405 becomes clogged, the controller 103 alarms and transmits a signal to an external control device. At this time, the operator can open the air inlet baffle 401 to remove the filter plate 405 for easy cleaning. Furthermore, when the temperature and humidity sensor 105 detects high humidity inside the pipe gallery 1, the controller 103 controls the dehumidifier 303 to operate, drawing air from inside the pipe gallery 1 through the filter disc 601 into the dehumidification inlet pipe 304, and then into the dehumidifier 303. The dehumidified air is then discharged through the dehumidification outlet pipe 306. Finally, the controller 103 controls the water pump 301 and the electrical... The solenoid valve 302 works in conjunction to discharge the water generated during the dehumidification process through the outlet pipe 3. Simultaneously, when the dehumidification inlet pipe 304 detects a low airflow inside, the controller 103 alarms. The operator then pulls the locking plate 603, causing the locking rod 602 to move, facilitating the removal of the filter disc 601. The filter disc 601 is then cleaned and reinstalled. When the operator releases the locking plate 603, the locking rod 602 is locked to the filter disc 601 by the locking spring 604 and the retaining groove 606, ensuring the stability of the filter disc 601.

[0032] The working process of this utility model is as follows: When using this equipment, the operator installs the entire device according to requirements. The operator then installs the filter plate 405 and the filter disc 601. At this time, the controller 103 controls the temperature and humidity sensor 105 to operate, thereby monitoring the temperature and humidity inside the pipe gallery 1. The monitoring data can be transmitted to an external control device. When the temperature and humidity sensor 105 detects that the temperature inside the pipe gallery 1 is low, the controller 103 controls the left-end fan 8 to rotate forward, causing the left-end fan 801 to rotate forward, thereby drawing outside air into the air inlet box 4 through the grille 201, and then through the filter plate 405 to the air inlet pipe 403. The air is then blown into the heating chamber 5. At this time, the controller 103 controls the heater 501 to heat the air inside the heating chamber 5 via the heating plate 503. Furthermore, the controller 103 controls the exhaust fan 504 to operate, thereby driving the exhaust fan 505 to rotate, thus expelling the heated air inside the heating chamber 5 through the exhaust plate 502. Simultaneously, the controller 103 controls the right-end fan 8 to operate in reverse, thereby driving the right-end fan 801 to reverse, thus expelling the low-temperature gas inside the pipe gallery 1 through the right-end grille 201. When the inlet flow meter 402 detects a small airflow entering the inlet pipe 403, the controller 103... If the filter plate 405 is determined to be clogged, the controller 103 will simultaneously issue an alarm and transmit a signal to an external control device. At this time, the operator can open the air inlet baffle 401 to remove the filter plate 405 for easy cleaning. Furthermore, when the temperature and humidity sensor 105 detects high humidity inside the pipe gallery 1, the controller 103 will control the dehumidifier 303 to operate, thereby drawing air from inside the pipe gallery 1 through the filter disc 601 into the dehumidification inlet pipe 304, and then into the dehumidifier 303. The dehumidified air will then be discharged through the dehumidification outlet pipe 306. The controller 103 will further control the water pump 301 and... The solenoid valve 302 works in conjunction to discharge the water generated during the dehumidification process through the outlet pipe 3. Simultaneously, when the dehumidification inlet pipe 304 detects a low airflow inside, the controller 103 alarms. Then, the operator pulls the locking plate 603, causing the locking rod 602 to move, facilitating the removal of the filter disc 601. The filter disc 601 is then cleaned and reinstalled. At this point, the operator releases the locking plate 603. The locking spring 604 and the retaining groove 606 then lock the locking rod 602 into place, ensuring the stability of the filter disc 601.
