Defoaming device for negative pressure concentrator

The utility model discloses a defoaming device for a negative pressure concentrator, which comprises a defoaming device, and is characterized in that the defoaming device is arranged in an evaporationchamber of the negative pressure concentrator and is adjacent to the lower part of a secondary steam outlet of the negative pressure concentrator, and the defoaming device comprises a filter screen.The anti-leakage device has the beneficial effects that the normal work of the concentrator (evaporation chamber) is not influenced, and meanwhile, the easy-to-foam materials can be prevented from leaking. The design is simple and easy to manufacture, no space needs to be occupied, installation of other defoamers is reduced, and the possibility of pipeline installation leakage under the negative pressure working condition is avoided. 本实用新型公开了一种负压浓缩器用的消泡装置，包括消泡装置，其特征在于，所述消泡装置安装在所述负压浓缩器的蒸发室内并邻近所述负压浓缩器的二次蒸汽出口的下方，所述消泡装置包括一滤网。本实用新型的有益效果在于在不影响浓缩器(蒸发室)的正常工作的同时，可以防止易起泡物料的跑料。这种设计简单易制造，无需占用任何空间，也减少了其他消泡器的安装，避免了负压工况下管道安装泄露的可能。
