Conventional water mist separators mainly separate gas and liquid by filter bag adsorption or by relying on the gravity difference of the medium. It is found that the separation efficiency of such separators is low. If necessary, multiple filtration or circulation filtration needs to be set up, which is costly and has a short service life. In addition, it has a large resistance to airflow and reduces kinetic energy. Summary of the invention

The angle filter screen is a stretched grid structure, forming a plurality of fine water mist channels, and a water mist airflow enters from one side of the angle filter screen in a manner perpendicular to the plane where each angle line is located, and a vortex is formed in the leeward area of ​​the angle filter screen during the process, and the precipitated water is allowed to flow freely down along the leeward area of ​​the angle filter screen.

[0006] Particularly, the included angle between the two side edges of the angled filter is 120°, and the included angle between the water mist airflow and the inlet side edge is 30°.

[0007] Particularly, a drainage hole is provided on the lower fixing plate.

[0008] In particular, the drainage holes are located at the corners of the V-shaped slots.

[0009] Particularly, a water guide strip is arranged on the lower fixing plate.

[0010] In particular, the folded filter screen is a metal stretched screen and is directly folded into shape.

[0011] Particularly, the upper fixing plate and the lower fixing plate are fastened by long screws.

[0012] In summary, the beneficial effects of the present invention are that the water mist separator has the following advantages:

[0013] 1) Design the angled filter structure and optimize the airflow path, which extends the airflow path, improves the separation efficiency and has a good effect;

[0014] 2) The grid-shaped water mist independent channel has low air flow resistance and retains the initial kinetic energy as much as possible;

[0015] 3) Easy to prepare, can use titanium, aluminum, stainless steel and other materials, low cost and long service life;

[0016] 4) It is convenient to collect and remove the precipitated water in time. BRIEF DESCRIPTION OF THE DRAWINGS
