Definitions

  • the invention relates to a device for filtering gases using biological filter material provided with microorganisms, with a device for moistening the gas to be filtered and with a ventilator which presses the gas flow through the biological filter mass.
  • biofilter systems for gas cleaning are known per se. It is known to set up a large-area aeration floor for the filter material, air which is adjustable in its humidity being pressed through the aeration floor from below through the filter material. Such large-area filter systems can also be used for composting or for storing materials to be aerated and the like. Such a large-area biological filter system is described for example in DE-36 34 377-AI.
  • the object of the invention is to provide a solution with which economically working small-volume filter systems are made possible.
  • this object is achieved according to the invention in that in a common housing in the direction of gravity from the bottom up the humidifying device, a support grid and at least one bed of biological filter material lying on it is provided, with the gas supply in the direction of gravity below and the outlet for the filtered gas flow is provided at the top in the direction of gravity.
  • the device itself can be designed in a modular design, for example a humidification module and at least one filter mass module can be combined into one unit.
  • biofilters are connected in parallel and / or in series.

Abstract

L'invention a pour but de fournir des installations de filtrationde faible encombrement et d'un fonctionnement économique, à l'aide d'un dispositif de filtration de gaz utilisant un matériau filtrant biologique présentant des micro-organismes, des moyens étant prévus pour humidifier le gaz à filtrer, ainsi qu'un ventilateur comprimant le courant gazeux à travers la masse filtrante biologique. Ce but est atteint grâce au fait qu'il est prévu dans une enveloppe commune, du bas vers le haut, par rapport au sens de gravité, un dispositif d'humidification (2), une grille support (11) et sur celle-ci, au moins une charge (12) constituée par une masse filtrante biologique, cependant qu'il est prévu, dans le sens de gravité, vers le bas, l'alimentation en gaz (13) et, dans le sens de gravité, vers le haut, la sortie (14) du courant gazeux filtré.
