Description

Technical Field

[0001] This utility model belongs to the field of ventilation and purification technology, and in particular relates to an air filter for ventilation ducts. Background Technology

[0002] With the improvement of people's living standards, building ventilation and purification are receiving increasing attention, and ventilation and purification systems have become an indispensable part of modern buildings. Current ventilation and purification systems typically consist of fans, ducts, and air vents. In large spaces such as lobbies and corridors of large buildings, multiple air vents need to be installed. The ducts are arranged in a crisscross pattern, and when the air is concentrated at the vents, the air velocity is high, which can easily cause discomfort, especially in office spaces where excessively high air velocities can also cause noise. Currently, ventilation ducts are mostly made of metal or plastic, and the air vents are installed on the ducts. Besides the noise and discomfort caused by excessively high air velocities, they cannot purify the air, requiring additional purification devices, increasing costs, and expanding the footprint of the ventilation and purification system. Utility Model Content

[0003] To address the aforementioned technical issues, this utility model discloses an air filter for ventilation ducts. While providing imperceptible airflow, it reduces the airflow velocity to avoid discomfort. Simultaneously, it purifies the airflow, delivering clean air to every corner of the building, and is easy to install and use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An air filter for a ventilation duct includes a metal pipe, an air inlet, an air pump, and a sealing device. The metal pipe is a flat pipe with an open bottom in the axial direction. A perforated structure is provided inside the open structure. The air inlet is located on the perforated structure. The air pump is located inside the metal pipe and connected to the air inlet.

[0006] Furthermore, the hollow structure includes a porous ceramic plate and two support plates. The two support plates are symmetrically fixed at intervals to the inner sidewall of the open metal tube structure in the axial direction, and the porous ceramic plate is placed on the support plates.

[0007] Furthermore, the ventilation duct air filter also includes a sealing device, which includes a sealing strip, a fixing strip, and a fixing bolt. The sealing strip is located between the support plate and the porous ceramic plate, the fixing strip is located on the upper part of the porous ceramic plate, and the fixing bolt passes through the porous ceramic plate, the sealing strip, and the support plate.

[0008] Furthermore, the porous ceramic plate has a pore size of 200-500μm, a porosity greater than 50%, and a thickness of 2-4mm.

[0009] Furthermore, the diameter of the air intake is 2-4cm, the length extending out of the porous ceramic plate is 4-8cm, the distribution density on the porous ceramic plate is 5-10 per meter, and it is evenly distributed on the porous ceramic plate.

[0010] Furthermore, the sealing strip is made of a flexible material with a thickness of 1-3 mm.

[0011] Furthermore, there are multiple fixing bolts, which are evenly distributed on the fixing strip, and the distance between the fixing bolts is 10-20cm.

[0012] This utility model discloses a ventilation duct with purification function, which combines a porous ceramic plate with a metal pipe, eliminating the need for air vents. While air is supplied through the duct, it is simultaneously discharged through the porous ceramic plate. The porous ceramic plate increases the air outlet area and reduces the air velocity, achieving imperceptible air delivery. Simultaneously, the abundant pores in the porous ceramic plate effectively intercept particulate matter and microbial aerosols in the air, achieving purification. An air intake is provided on the porous ceramic plate; an air pump draws ambient air into the duct through the intake, maintaining positive pressure within the duct. Under pressure, air passes through the pores of the porous ceramic plate, achieving both air supply and purification, thus realizing internal circulation and purification.
