A bad smell in first fermenter double discharging system of a barnyard manure factory

摘要

PURPOSE: An odor discharge system is provided to dual decompose bad smell of a first fermentation tank which decomposes the bad smell by using microbes. CONSTITUTION: An odor discharge system of livestock excretion composting facilities comprises a first fermenter(5), a second fermenter(6), and a third fermenter(7). At the lower part of the first fermenter, one end of a suction pipe(10) is connected. The suction pipe is connected to a suction fan(11) and is connected to one end of a blast pipe(20). The blast pipe is connected to the lower part of the third fermenter and blows the bad smell gas of the first fermenter into the third fermenter. The microorganism included in the compost of the third fermenter decomposes the bad smell gas sent to the third fermenter. A drain hole(40) is formed at one side of the suction pipe.
