Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1~5, in the utility model embodiment, a kind of high-efficiency blade demister, including demister shell 12,
The middle part of baffle plate blade 4, retaining ring 8, baffle plate inner wall 6, distance rod 11 and fixed stop 3, the demister shell 12 is uniform
Equipped with baffle plate blade 4, baffle plate blade 4 can be such that gas and liquid is separated using inertia, the baffle plate blade 4
Top is equipped with surface press strip 2, and surface press strip 2 has the function of fixation, and the end of the surface press strip 2 is provided with tight fixed bolt 1,
And the lower middle side part of baffle plate blade 4 is equipped with connecting plate 5, connecting plate 5 has the function of that support is fixed, the demister shell 12
