AI Technical Summary
The existing air detection devices have multi-functional integrated detection, but various air pollution accurate data need to be matched with the corresponding gas detection device with high accuracy to detect the required data separately, resulting in multiple monitoring equipment being installed in multiple locations, making it difficult to accurately detect pollution data in the same place of air, and the contact area between the air and the detection ends of multiple detection equipment is small, which affects the accuracy of the detection data.
A multiple air detection diversion device is designed. The air flow inside the diversion cylinder is directed into the air expansion plate through multiple diversion tubes. The diversion plate expands the air flow and reduces the capacity and flows annularly through the tangent direction of the cyclone cylinder. The air flow in the cyclone cylinder surrounds the detection end of the detection equipment, ensuring full surround contact between the gas and the detection equipment, with a large contact area, and achieving synchronous and accurate detection of the same air flow by multiple detection equipment.
Through this equipment, multiple detection equipment can ensure synchronous and accurate detection of different air pollution data of the same airflow by multiple detection equipment, improve the accuracy and consistency of the detection data, and solve the problems of multi-point installation and small contact area.
