Abstract
The purpose of this study is to find more efficient technologies to solve the problem of capturing and extract a contaminant cloud over a larger surface, e.g. workbench. The main air pollution that the technology shall be able to control is welding fumes, and the main focus is to obtain a contaminant free breathing zone. Today’s products for extracting welding fumes are either an extraction arm that continuously needs to be re-positioned to maintain a sufficient capturing or a down- and back draught table that consumes a lot of energy due to high airflow rates.
The chosen technology for solving the problem is to control and transport the polluted air over the surface towards an extraction hood with a push-jet, this technology is usually... (More)
The purpose of this study is to find more efficient technologies to solve the problem of capturing and extract a contaminant cloud over a larger surface, e.g. workbench. The main air pollution that the technology shall be able to control is welding fumes, and the main focus is to obtain a contaminant free breathing zone. Today’s products for extracting welding fumes are either an extraction arm that continuously needs to be re-positioned to maintain a sufficient capturing or a down- and back draught table that consumes a lot of energy due to high airflow rates.
The chosen technology for solving the problem is to control and transport the polluted air over the surface towards an extraction hood with a push-jet, this technology is usually referred to as push-pull systems.
The technology is studied and tested to determine if it is applicable for welding fume extraction. Simultaneously with the performance tests the push-pull technology is developed into a realizable future product in the company’s product range.
The push-pull system is proven to be a robust solution for maintaining a contaminant free breathing zone and the final prototype offers a flexible workspace were no positioning is needed to a much lower airflow than a draught table. The conclusion of the study is a number of design guidelines for future product development. (Less)
