Shenyang ventilation pipeline The local exhaust hood is used to catch harmful substances. Its performance has a direct impact on the technical and economic indicators of the local exhaust system. The local exhaust hood with good performance, such as the airtight hood, can obtain good working effect as long as the air volume is small. Due to different production equipment and operation, the exhaust hood has various forms.

The ducts conveying gas in the ventilation system are called air ducts, which connect various equipment or components in the system as a whole. In order to improve the economy of the system, the gas flow rate in the air duct should be reasonably selected, and the pipeline should be as short and straight as possible. Shenyang Ventilation duct Usually, it is made of materials with smooth surface, such as steel sheet, PVC sheet, and sometimes concrete, brick and other materials.

In order to prevent air pollution, when the amount of harmful substances in the discharged air exceeds the emission standard, it needs to be treated with purification equipment, and discharged into the atmosphere after reaching the emission standard. Purification equipment includes dust remover and harmful gas purification device.

The connection between the air supply duct of Shenyang ventilation duct and the air outlet of the main unit of the air cooler shall be sealed; If the outdoor pipeline is too long, it should be designed for thermal insulation, while the indoor pipeline generally does not need thermal insulation. If branch pipes exist in the design, valves or air distribution baffles must be installed on the branch pipes to adjust the air volume so that the air volume of the branch pipes can reach the design value.

The fan of Shenyang ventilation duct will produce vibration when it is running. In order to influence the fan vibration on the pipeline, a section of hose (such as canvas hose) is used at the place where the pipeline connects with the fan. Straight pipes are generally used at the outlet of the fan. When it is required to install elbows at the outlet of the fan due to the limitation of the installation position, the direction of the elbow shall be the same as the rotation direction of the fan impeller.
