Description

Technical Field

[0001] This utility model relates to the field of air suction duct technology, specifically an air suction duct. Background Technology

[0002] With increasingly stringent environmental regulations, coating production lines must effectively control the emission of volatile organic compounds (VOCs). Traditional exhaust systems are simple in design and cannot meet the requirements of high efficiency and low energy consumption, resulting in serious environmental pollution and increasing the production costs of enterprises.

[0003] In recent years, various new air suction duct technologies have emerged, aiming to improve the efficiency of waste gas treatment while reducing energy consumption. However, they generally suffer from problems such as complex structure and difficult maintenance. Although the various treatment technologies on the market have their own characteristics, they still have many limitations. For example, traditional ventilation ducts cannot ensure uniform extraction of waste gas in the workshop and are prone to dead zones. Based on this, an air suction duct is proposed. Utility Model Content

[0034] In this embodiment, the suction pipe 1 and the suction flare pipe 5 work together to uniformly extract exhaust gas from the workshop. This design ensures comprehensive exhaust gas extraction.
