AI Technical Summary
When dealing with toxic solvent liquid barrels, traditional exhaust systems have problems such as large air volume, high energy consumption, long distance from the barrel edge, too small wind speed and easy to block the barrel edge, resulting in inconvenient operation.
An annular strip exhaust hood is designed, including exhaust plates, exhaust troughs, placement tables, exhaust ducts, funnel-shaped hoods, cleaning components and collection boxes. By optimizing the structure and component layout, it ensures effective collection of harmful gases and easy cleaning, and avoids blocking the edges of the barrels.
It realizes efficient capture of harmful gases, reduces energy consumption, ensures that the barrel edges are not blocked, and improves operational convenience and wind speed control.

Abstract
Description
Technical Field
[0001] The present application relates to the field of exhaust hoods, and in particular to an annular slit exhaust hood. Background Art
[0002] Exhaust hoods are devices that capture pollutants within local exhaust systems and are a crucial component of these systems. Exhaust hoods can capture harmful substances, control the flow of polluted gases, and prevent them from spreading into the indoor air. Airflow through the hood openings can capture harmful substances directly at their emission points or control their spread within the workshop, ensuring that concentrations of harmful substances in indoor work areas do not exceed national health standards. Currently, barrels containing toxic solvents are commonly used in industrial production processes. Traditional exhaust systems (such as upper suction hoods) suffer from high air volume, high energy consumption, a long distance between the hood opening and the barrel edge, and low air speeds. Adjusting the hood opening closer to the barrel edge can block the edge, making operation difficult.
[0003] Therefore, a ring-shaped slotted exhaust hood that avoids obstruction is needed. Utility Model Content
