[0015] Embodiment

[0016] As Figure 1 shown, a kind of hydrophobic pipeline impurity filtering device, including steam main pipe 5, with steam main pipe 5 connection hydrophobic pipeline 6, hydrophobic pipeline 6 is connected with hydrophobic valve group, hydrophobic valve group includes hydrophobic primary valve 1, hydrophobic valve 3 and hydrophobic secondary valve 4, Y-type filter 2 is arranged between hydrophobic valve 3 and hydrophobic primary valve 1, hydrophobic secondary valve 4 is arranged on the side of hydrophobic valve 3 away from Y-type filter 2. After using this structure, by installing Y-type filter 2 between hydrophobic primary valve 1 and hydrophobic valve 3, to realize the filtration of impurities in hydrophobic, can make hydrophobic valve 3 long-term in the state of hydrophobic unobstructed, guarantee steam main pipe 5 will not be affected by hydrophobic blockage steam quality, improve thermal efficiency.

[0017] In use: when the impurities in the hydrophobic enter the hydrophobic pipeline 6, first enter the Y filter 2, the impurities will be accumulated in the bottom of the Y filter 2, and will not enter the hydrophobic valve 3, so that the hydrophobic pipeline is unobstructed, and in the later period, only the impurities accumulated in the Y filter 2 need to be cleaned regularly, without the need of removing and cleaning the pipeline impurities, so that the hydrophobic device can be kept in a long-term unobstructed state, the steam main pipe 5 can be ensured to be unobstructed, the steam quality can be ensured, the heat efficiency is improved, the construction is convenient, the transformation and maintenance cost is low, and the service life of the hydrophobic valve 3 can be prolonged.

[0018] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
