Emergent bypass device of outlet duct on waste oil recovery alembic

The utility model relates to an emergent bypass device of outlet duct on waste oil recovery alembic, including the each other emergent pipeline and the filter equipment of intercommunication, the filter equipment air inlet passes through the blast pipe and corresponds to connect and retrieve the alembic gas outlet at waste oil, and pipeline is connected to the filter equipment gas outlet, and emergent pipeline one end is passed filter equipment and is stretched into its inner chamber along the lateral wall down, and the other end corresponds intercommunication pipeline, is equipped with the valve body in the middle part of the emergent pipeline, set up emergent pipeline, provided emergent pressure release when filter equipment block up to become invalid, directly carry the oil vapour to pipeline, set up the U type passageway of inversion, avoid in oil vapour or the steam impurity to condense in pipeline and flow back extremely that the emergency pipeline causes emergent pipe blockage. 本实用新型涉及种废油回收蒸馏罐上出气管的应急旁路
