DEVICE FOR AIR PURIFICATION WITH BIO FILTERS AND METHOD FOR SUCH A AIR PURIFICATION.

摘要

Device for air purification with biofilters (20), the waste air being withdrawn via piping (1) from a source, such as for example a kitchen, grilling station, frying station or the like and being forced by means of a fan (2), into the biofilter or biofilters (20), is to be developed so as to allow a direct connection of the fan to the humidifier (4), the design of which is to allow operation even with, for example, air contaminated with fat without the danger of clogging for the biofilter (20), where the humidifier (4) connected upstream of the biofilter (20) is to be simply assembled, able to be operated economically and to be cleaned without significant outlay. This is achieved in that a humidifying tower (4) is connected between the fan (2) and the biofilter (20), the tubular housing of which tower is provided at the lower end of the vertical axis with a waste water sump (15, 16) and is provided above this with a tangentially directed air entry (3) which can be flange-mounted to the fan (2), and the upper end of which tower has a centrally connected overflow pipe (18) to connect the humidifier (4) to the biofilter (20), at least two horizontally arranged spraying planes being provided in the tubular housing and each of these spraying planes being furnished with an arrangement of spraying nozzles (10).
