Zusammenfassung:PROBLEM TO BE SOLVED: To provide a biological deodorization apparatus for preventing corrosion of a pipeline caused by sulfuric acid generated inside the processed gas pipeline.SOLUTION: A biological deodorization apparatus 10 includes: a biological deodorization tower 20 into which malodorous gas Gis introduced; and a carrier-filled layer 21 which is filled with a microorganism-retaining carrier and disposed inside the biological deodorization tower 20, and generates a processed gas Gby decomposing the malodorous gas G. In the biological deodorization tower 20, a first sprinkling unit 40 for sprinkling water toward the carrier-filled layer 21 is disposed. A processed gas pipeline 30 for exhausting the processed gas Gfrom the inside to the outside of the biological deodorization tower 20 is connected to the biological deodorization tower 20, and at least one part of the processed gas pipeline 30 is inclined to a horizontal plane.SELECTED DRAWING: Figure 1 【課題】処理ガス配管内に生成した硫酸に起因する配管の腐食を防止する生物脱臭装置を提供する。【解決手段】生物脱臭装置10は、悪臭ガスGAが導入される生物脱臭塔20と、生物脱臭塔20内に配置され、微生物を保持した担体が充填されるとともに悪臭ガスGAを分解して処理ガスGBを生成する担体充填層21とを備えている。生物脱臭塔20内に、担体充填層21に向けて水を散水する第1散水部40が配置されている。生物脱臭塔20に、生物脱臭塔20の内部から外部へ向けて処理ガスGBを排出する処理ガス配管30が連結されており、処理ガス配管30の少なくとも一部が水平面に対して傾斜している。【選択図】図1
