[0023] The separation structure 1 includes a frame 11, and a plurality of blades 13 are arranged inside the frame 11. The gas passes through the flow channel between the blades 13 to block the rainwater in the air and ensure the effect of rainwater separation. It is necessary to test the distance between the blades 13 and balance the rainwater separation effect and the resistance of gas flow. Here, the spacing between the two blades 13 is 10 to 20 mm. The blade 13 includes a main body 131. The main body 131 is completed three times to form a four-segment structure, and the lengths of the two ends in the middle are equal and vertically arranged. The lengths of the two segments at the edge are equal and coplanar. That is, the bending points of the two edges are connected, and the connecting line and the two middle segments form an isosceles right triangle. The purpose is to enable the gas to quickly change the gas flow direction when passing through, and at the same time increase the length of the flow channel, and the rainwater in the gas will hit the side wall of the main body 131, that is, to achieve the effect of rainwater separation.

[0024] The main body 131 is fixedly connected with a first water retaining groove 132 and a second water retaining groove 133, and the cross-sectional profiles of the first water retaining groove 132 and the second water retaining groove 133 are both L-shaped, the first water retaining groove 132 is fixedly connected at the bend of the edge of the main body 131, and is located below the main body 131, and the second water retaining groove 133 is fixedly connected at the bend in the middle of the main body 131, and is located above the main body 131. That is, the first water retaining groove 132 and the second water retaining groove 133 are located on both sides of the main body 131, and rainwater hits the side wall of the main body 131, and under its own kinetic energy, it converges to the first water retaining groove 132 or the second water retaining groove 133, and two channels are set to improve the separation effect of rainwater.

[0025] Furthermore, the blade 13 is integrally formed, that is, produced by extrusion molding.
