The outer side of the partition plate 7 is higher than the inner side, and a gap is formed between the partition plate 7 and the bottoms of the first water drain groove 2 and the second water drain groove 6 respectively to form a diversion channel.
In addition, the number of the partition plates 7, the water drain grooves and the water drain hooks can be increased or decreased according to working condition requirements, so that the filtering efficiency is greatly improved.
Compared with the traditional inertial stage blade structure, the multi-scale vortex is realized on the longitudinal dimension by arranging the partition plates 7, the inertial stage blades are obliquely arranged at multiple intervals, the large vortex formed in the water-repellent tank is divided into multiple scale vortices by different arrangement of the partition plates 7, the coupling blades are in a multi-scale water-repellent tank in the spreading direction, and the filtering efficiency is higher by collaborative filtering. The trapping capability of particles with different particle diameters is enhanced from a multidimensional angle, the inclined arrangement of the partition plates 7 also accelerates the flow guiding rate of the blades, and the rolling of liquid drops in the flow guiding channel is accelerated. On the premise of keeping the resistance loss relatively stable, the filter has the advantages of high flow guiding rate, simple structure and strong filtering performance.
The partition plates 7 are unevenly distributed in the first water-repellent tank 2 and the second water-repellent tank 6 respectively, namely, the interval between the partition plates 7 in the first water-repellent tank 2 and the second water-repellent tank 6 is unequal. For example, the intermediate arrangement may be somewhat loose and the edge arrangement may be somewhat dense. Therefore, the multi-spacing inclined partition plates enable the inertial stage blades to realize multi-scale vortex in the longitudinal dimension, couple the multi-scale water-repellent tanks in the expanding direction of the blades and cooperatively filter.
The partition plates 7 are obliquely arranged in the first water-repellent tank 2 and the second water-repellent tank 6 respectively, the angle range is 140-165 degrees, and the flow guiding rate of the blades is accelerated through the oblique arrangement of the partition plates 7.

The arrangement direction of the first water drain groove 2 is opposite to that of the second water drain groove 6, the direction of the first water drain groove 2 protrudes inwards, and the direction of the second water drain groove 6 protrudes outwards.
The front flow guiding section 1 and the rear flow guiding section 4 are both composed of straight line sections and circular arc sections, the edge parts of the front flow guiding section and the rear flow guiding section are triangular, and the flow guiding section and the edge parts of the drain hooks are in rounded transition, so that the resistance loss is reduced. Specifically, the front end of the front diversion section 1 is in circular cutting transition with the front ends of the first water drain groove 2 and the second water drain groove 6, the upper part of the front end of the rear diversion section 4 is in circular cutting transition connection with the tail end of the first water drain groove 2 through the first water drain hook 3, and the lower part of the front end of the rear diversion section 4 is in circular cutting transition connection with the tail end of the second water drain groove 6 through the second water drain hook 5.

The hydrophobic slot shutter structure of the scheme improves the capability of capturing particles with various particle diameters, and the inclined shutter structure accelerates the falling of a liquid film and increases the efficiency of gas-liquid separation. The device has the advantages of being applicable to high flow rate conditions, high in flow guiding rate, simple in structure and strong in filtering performance.
