Abstract

Entlang einem im wesentlichen flächig ausgedehnten Arbeitsfeld soll die Schadstoffkonzentration in der Atemluft vermindert werden. Die dazu vorgesehene mobile Anordnung umfaßt mindestens eine am Rand (1A) des Arbeitsfeldes (3) angeordnete Abluftöffnung (7). An dem etwa gegenüberliegenden Rand (1B) des Arbeitsfeldes ist mindestens eine einen Zuluftstrom erzeugende Zuluftquelle (11) angeordnet. Diese erzeugt einen entlang dem Arbeitsfeld im wesentlichen zur Abluftöffnung (7) gerichteten Zuluftstrom. Die Erfindung betrifft auch ein Verfahren zur Verminderung der Konzentration von Luftschadstoffen an der Atemposition eines Arbeiters, die sich von der zu bearbeitenden Stelle entfernt befindet. Zwischen der zu bearbeitenden Stelle (50) und der Atemposition (15) wird ein Luftschleier (53) zwischen einer Zuluftöffnung (54) und einer Abluftöffnung (55) erzeugt.

Figure 00000001
The pollutant concentration in the air we breathe should be reduced along an essentially extensive working area. The mobile arrangement provided for this purpose comprises at least one exhaust air opening (7) arranged at the edge (1A) of the working field (3). At least one supply air source (11) generating a supply air flow is arranged on the opposite edge (1B) of the working field. This generates a supply air flow directed essentially towards the exhaust air opening (7) along the working field. The invention also relates to a method for reducing the concentration of air pollutants at the breathing position of a worker, which is located away from the area to be processed. An air curtain (53) is generated between an inlet air opening (54) and an exhaust air opening (55) between the point (50) to be processed and the breathing position (15).
