ODOR ELIMINATION DEVICE FOR SEWER USING NEGATIVE PRESSURE METHOD

摘要

The present invention relates to an odor elimination device for a sewer using a negative pressure method, comprising: an odor-suctioning odor suction port connected and fixed by a connecting pipe, a collecting pipe, or the like to one outer side of a sewer or a sewer pipe, a plurality of suction pipes being connected to and provided on one side of a collecting pipe (16), and provided with a suction port (13) on the lower surface of a suction pipe; an odor discharge unit provided with a discharge pipe collecting and discharging to the outside the odor of the odor suction port, provided with a ventilator or the like at the end of the discharge pipe, and generating a negative pressure phenomenon attributable to an air volume; and a connecting unit provided with a connecting pipe to be capable of functioning as a joint by connecting the odor suction port and the odor discharge unit to each other. According to the present invention, the odorous air in the sewer or the sewer pipe is collected and discharged far away to the outside through the pipe disposed by combination of multiple pipes on one side of the sewer or the sewer pipe. Before the discharge, various odors in the sewer or the sewer pipe are guided to flow to one spot by the negative pressure method for lowering the air pressure in the sewer or the sewer pipe. Accordingly, various discomforts in daily life can be forestalled, including the odor-based discomfort caused when the odor in the sewer or the sewer pipe spreads entirely or partially above to a road or a street.;COPYRIGHT KIPO 2018
