Description

Centralized collection and treatment device for pipeline gas Technical Field The utility model relates to the technical field of dangerous chemical storage, in particular to a centralized collection and treatment device for pipeline gas. Background In the daily ship operation of the liquid chemical storage unit, when the ship side and the shore side are connected through pipelines, 0.4Mpa nitrogen is required to be used for carrying out an airtight test on the pipelines, and after the test, the nitrogen reserved in the pipelines is disposed before the ship unloading operation. In the prior art, nitrogen is generally discharged by adopting a method of firstly discharging through a DN20 exhaust valve in front of a wharf line cleaner, wherein the method is slow in discharging, and possibly polluting the environment by directly discharging residual part of chemicals to the outside before an inner pipeline, and secondly directly discharging the nitrogen into a storage tank, and the method is fast in discharging, but is easy to damage accessories in the storage tank, and is only used when an empty tank is used for goods feeding. In addition, after ship unloading is finished, the unloading pipeline is required to be passed through a ball and swept, and residual part of gas in the feeding pipeline is remained after the sweeping is finished, so that the departure pump can not normally operate due to residual gas in the pipeline, departure can be ensured to be normal through manual exhaust and a regulating valve, time and labor are wasted, and departure efficiency is low.
