Abstract

The invention relates to a packing with raised grain for biologically treating waste gas. The packing is a grille body of which the external outline surface is a spherical surface enclosed by two hemispheres; the binding surface of the two hemispheres forms an equatorial surface; the outer ring of the equatorial surface is an equatorial ring; each of the hemispheres is provided with at least one latitude ring in parallel with the equatorial ring; a plane which is provided with the latitude ring is a latitude plane; blades divergently distributed around the axes of the hemispheres connect adjacent latitude planes or the equatorial plane and the adjacent latitude plane thereof; the edges of the blades are supported between the adjacent latitude planes or the equatorial plane and the adjacent latitude thereof, and the external circle-arc edges thereof form the external outline of the sphere; grille units are formed by the adjacent blades; the blades are provided with a rough surface facilitating the mounting of microorganism; the packing is provided with a through channel along the axes of the two hemispheres; the inner surface of each grille unit opposing to the external outline surface thereof form the outer edge of the channel.

Description

technical field [0001] The invention relates to a packing used for biological treatment of waste gas, in particular to a packing used in a biological trickling filter bed of a waste gas biological treatment device. Background technique [0002] Because of its large biomass and controllable growth conditions of microorganisms, the biological trickling filter bed is a highly efficient reactor in the waste gas biological treatment device. Therefore, it is required that the biological filler used has sufficient specific surface area and sufficient gaps and channels, which can not only facilitate the attachment and growth of active microorganisms, but also facilitate the shedding of aged biofilms to flow away through the filler gap. [0003] Since biological waste gas treatment is a new technology in recent years, most of the fillers currently used are replaced by traditional chemical fillers, such as Pall rings and Raschig rings of various materials, often because the specific s...
