Initial position: the sliding sleeve 1111 on the sphere 1110 drives the cone 1112 to adjust to a proper angle, and the turning plate 1142 closes and seals the cone cavity outlet 1117.

The working principle is as follows: the produced oil is pumped through the hydraulic pump 1020 into the cavity formed by the filter plate 1070, the filter inspection plate 1071 and the filter bottom plate 1072. Due to the increase in pressure within the chamber, oil is projected through the filter holes 1073 in the filter plate 1070 and into the first tank 1030 of the first tank 1030. During this process, the solid particles are thrown furthest because of their highest density and fall onto conveyor belt 1090. The conveyor belt 1090 is rotated by the rollers 1091 and conveys the solid particles thereon out of the first housing 1030 via the conveyor 1032. During the throwing process, the gas with moisture is separated and enters the folded plate cavity 1083 formed by the variable folded plate 1082 and the folded plate 1081, and during the upward movement of the gas with moisture in the folded plate cavity 1083, the moisture particles continuously impact the protruding inner walls of the variable folded plate 1082 and the folded plate 1081 and are gradually collected into water droplet particles on the inner walls, so that the purpose of water diversion is achieved. In addition, because the folded plate cavity 1083 becomes narrower from bottom to top, the speed of the gas inside the folded plate cavity becomes higher, and the temperature of the gas is also reduced correspondingly, so that the water distribution effect is enhanced. The dried gas enters header 1080 and is delivered to pneumatic pump 1040 via header output port 1085 and conduits. The remaining oil and water containing emulsion is deposited inside the first tank 1030, through the first tank output 1035 and conduit into the second tank 1050.

The dried gas is pumped into the bottom plate air passage 1061 through the pneumatic pump 1040 and the pneumatic pump output port 1042, the bottom plate air passage 1061 communicates with the ball cavity 1113 of each ball cavity 1113 through the pad stage 1100, the dried gas enters the cone cavity 1116 through the ball cavity outlet 1114, the dried gas enters the next ball cavity 1113 through the cone cavity outlet 1117, and the dried gas pushes the turning plate 1142 into the interior of the second box 1050 through the cone cavity outlet 1117 and the nozzle ring cover 1140. As the dried gas continuously pushes each turning plate 1142 and emerges from between, the dried gas emerges from the emulsion inside the second box 1050 in the form of small bubbles, and the resulting stable and small force continuously impacts the small moisture particles in the emulsion to fuse them into large moisture particles, so as to overcome the buoyancy force and deposit them. During the continuous movement of the drying gas, water is continuously carried out from the emulsion, thereby enhancing the separation effect of the emulsion. Finally, the separation effect of the lower-layer moisture, the middle-layer petroleum and the upper-layer gas is realized in the second box body 1050. The gas-oil-water three-phase is finally discharged via gas phase output port 1053, oil phase output port 1055, and water phase output port 1057, respectively.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
