The barrel body 1 comprises a cylindrical barrel body 11 and side walls 12 arranged on two sides of the barrel body 11. In this embodiment, the barrel body 1 is cylindrical as a whole, and the axis is parallel to the ground.

The side wall 12 is arc-shaped and protrudes outwards.

The separating elements 2 are arranged at a distance from the side wall 12 so that a separating space 111 is formed between two separating elements 2 and a mixing space 112 is formed between the side wall 12 and the separating elements 2.

The separating assembly 2 comprises a grating 21 close to the adjacent side wall 12, a hole plate 23 opposite to the grating 21 far away from the adjacent side wall 12, and a filter screen 22 arranged between the hole plate 23 and the grating 21, wherein filter holes 211 are formed in the grating 21, the filter screen 22 and the hole plate 23. Wherein, the grating 21 mainly plays a supporting role, and the filter screen 22 and the pore plate 23 play a role in separating gas and liquid.
