Abstract

The air recovery system reduces or avoids dust emmission used with ventilation or dust extraction systems to attain permissible pollution while using minimal power. The atmosphereic sorting installation works with a blower and a suction section. A part or all of the exhausted air is recirculated after pre-cleaning in order to reduce or avoid dust-carrying air being exhausted into the atmosphere. Thus part or all of the partially cleaned air is pumped back into the area to be ventilated.

Description

Luftrückführung zur Verminderung oder Vermeidung von Staubimmission Bei lufttechnischen Verfahren, insbesondere bei Absauganlagen, ist für die Abscheidung staubförmiger Verunreinigungen auf die zulässigen Immissionswerte ein großer Aufwand erforderlich. Air recirculation to reduce or avoid dust immission In ventilation processes, especially in extraction systems, is for the separation dust-like contamination on the permissible immission values a great effort necessary.

Bei lufttechnischen Sortieranlagen, die mit einem Blas- und einem Saugteil arbeiten, ist es möglich zur Verminderung oder zur Vermeidung von staubhaltiger Abluft einen Teil oder alle Abluft nach Vorreinigung für die Blasluft wieder zu verwenden. In the case of ventilation systems that have a blower and a Working suction part, it is possible to reduce or avoid dusty Exhaust air closes part or all of the exhaust air again after pre-cleaning for the blown air use.

Dadurch wird der Aufwand zur Entstaubung auf zulässige Immissionswerte vermindert oder ganz überflüssig. This reduces the effort for dedusting to permissible immission values reduced or completely superfluous.

Claims (1)

dj Der Schutzanspruch ist dadurch gekennzeichnet, daß bei lufttechnischen Verfahren, speziell bei Sortieranlagen, mit Blas- und Saugluft ein Teil oder alle Saugluft nach einer Vorreinigung als Blasluft wieder verwendet wird.dj The protection claim is characterized in that with ventilation Process, especially in sorting systems, with blown and suction air, some or all Suction air is reused as blown air after pre-cleaning.
