Description of drawings
Fig. 1 is the utility model oil and gas multiphase flow knock out drum structural profile schematic representation.
Among the figure, 1-oil and gas import pipe, 2-oil gas vent pipe, 3-pressure gauge connecting tube, 4-safety valve connecting tube, the 5-liquid-discharging tube, the 6-bypass line is taken over, and 7-cushions tank body, 8-jar base.
Embodiment
Embodiment 1: with an oil and gas multiphase flow knock out drum is example, and the utility model is done further explain.
Consult Fig. 1.The utility model oil and gas multiphase flow knock out drum comprises buffering tank body 7, and buffering tank body 7 is the vertical enclosed cylinder bodily form jar of the steel plate welding of 8mm, buffering tank body 7 diameter 800mm, height 2300mm.The buffering tank body about in the of 7 two ends be arc surface shape.Buffering tank body 7 is weldingly fixed on the top of cylindrical can base 8.
Vertical tank skin is welded with an oil and gas import pipe 1 and a bypass line adapter 6 on buffering tank body 7 walls; Oil and gas import pipe 1 is positioned at buffering tank body 7 medium positions; Bypass line adapter 6 is positioned at the bottom of oil and gas import pipe 1; Oil and gas import pipe 1 is taken over 6 the inners with bypass line and is communicated with tank body is interior, and the outer end is welded with flange.The height distance tank base 1200mm of oil and gas import pipe 1, bypass line is taken over 6 height distance tank base 600mm.Vertical tank skin is welded with oil gas vent pipe 2 on the wall of buffering tank body 7; Oil gas vent pipe 2 takes over 6 at same horizontal position with bypass line; Oil gas vent pipe 2 penetrates in the buffering tank body 7 and the inner of oil gas vent pipe 2 is connected with and cushion the parallel straight tube of tank body 7 center lines, and the height of straight tube upper end is identical with the height of oil and gas import pipe 1.Vertical tank skin is welded with pressure gauge connecting tube 3 on the wall of buffering tank body 7; Pressure gauge connecting tube 3 is positioned at the top of oil gas vent pipe 2; Pressure gauge connecting tube 3 penetrates in the buffering tank body 7 and the inner of pressure gauge connecting tube 3 is connected with and cushion the parallel straight tube of tank body 7 center lines, and the straight tube upper end is at the top of buffering tank body 7.On buffering tank body 7 bottom outer walls, be welded with a liquid-discharging tube 5, liquid-discharging tube 5 penetrates in the buffering tank body 7 and the inner of liquid-discharging tube 5 is connected with and cushion the parallel straight tube of tank body 7 center lines, and liquid-discharging tube 5 inner straight tubes extend downwardly into the bottom of buffering tank body 7.On buffering tank body 7 walls, be welded with safety valve connecting tube 4.
