Below in conjunction with accompanying drawing 1 explanation detailed construction of the present invention and use.The integrated gas-liquid separator of level control shown in Figure 1, gas-liquid two-phase fluid separates in floating drum, and the meaning of each sequence number is among the figure: 1 adjusting handle, 2 sealing nuts, 3 sealing rings, 4 regulate thread bush, and 5 regulate the screw thread slide bar, 6 regulate sliding sleeve, 7 separator urceolus, 8 floating drums, 9 feed pipes, the outlet of 10 tapping valves, 11 draining valves, 12 tapping valve shanks, 13 tapping valves inlet, 14 floating drum bottom outlets, 15 floating drum bottom side holes, 16 blast pipes, 17 regulate screw thread litter dop.Wherein adjusting handle 1, adjusting thread bush 4, adjusting screw thread slide bar 5 and adjusting sliding sleeve 6 are formed, adjusting handle 1 and adjusting screw thread litter 5 rigid attachment, regulate thread bush 4 and regulate screw thread slide bar 5 thread connection, regulate screw thread slide bar 5 lower ends and one diameter is arranged greater than the ailhead of regulating sliding sleeve 6 internal diameters, be inserted in and regulate in the sliding sleeve 6, one bore is arranged less than the reducing of ailhead and regulate sliding sleeve 6 upper ends, make screw thread litter 5 lower ends and regulate sliding sleeve 6 and form and be slidingly connected.This manual adjustment means can be used for setting the maximum opening of tapping valve, also can be with tapping valve positive closing or enforced opening.In order to prevent that gas from leaking, manual adjustment means has been set up sealing ring 3 and sealing nut 2, and sealing nut 2 and adjusting thread bush 4 adopt the screw threads assembling to connect.Floating drum 8, draining valve 11 and discharge opeing valve rod 12 are formed liquid level automatic control mechanism, and draining valve 11 and tapping valve shank 12 constitute the tapping valve of this liquid level automatic control mechanism.For the liquid that enters in the floating drum is discharged and the gas effusion, the floating drum bottom outlet 14 of floating drum 8 has more than 2, arranges that evenly floating drum bottom side hole 15 also has more than 2, and the aperture is identical, and the hole heart is evenly distributed on same circumference.Floating drum 8 bottoms that connect one with draining valve 11 are provided with valve rod hole and a plurality of tapping valve inlet 3, make liquid inflow valve pocket in the floating drum, and tapping valve shank 12 can slide in valve rod hole.Feed pipe 9 passes base plate and floating drum bottom outlet 14 of separator urceolus 7 from bottom to top respectively, stretch into space, middle and upper part in the floating drum 8, feed pipe 9 does not have leakage with the base plate of separator urceolus 7 and is connected, and the external diameter of feed pipe 9 is slightly less than floating drum bottom outlet 14, does not hinder floating drum 8 and fluctuates.
The operation of setting the tapping valve aperture by manual adjustment means is as follows: (1) turn adjusting handle 1, adjusting screw thread slide bar 5 is moved down, the top board of the adjusting screw thread litter dop 17 contact floating drums 8 in regulating sliding sleeve 6, continuation is with equidirectional turn handwheel 1, interlock floating drum 8, tapping valve shank 12 move down, seal tapping valve outlet 10 up to tapping valve shank 12, this moment, tapping valve was in the positive closing state, and the material in the separator can not export 10 from tapping valve and discharge.(2) the turn adjusting handle 1, make to regulate on the screw thread slide bar 5 and move, make the adjusting screw thread litter dop of regulating in the sliding sleeve 6 17 leave the top board of floating drum 8, but do not contact the reducing of regulating sliding sleeve 6 upper ends, this moment, but tapping valve was in the state of a control between the opening and closing, regulate screw thread litter dop 17 more up, then the maximum opening of tapping valve is big more.(3) on the basis of operation (2), continuation is with equidirectional turn handwheel 1, make adjusting screw thread litter dop 17 contacts of regulating in the sliding sleeve 6 regulate the reducing of sliding sleeve 6 upper ends, continue turn handwheel 1, move on interlock floating drum 8, the tapping valve shank 12, make tapping valve shank 12 leave tapping valve outlet 10, this moment, tapping valve was in the enforced opening state, material in the separator can export 10 from tapping valve all the time and discharge, as continue turn handwheel 1 tapping valve shank 12 is moved on further, then the positive opening of tapping valve increases.
The liquid level automatic control process of gas-liquid separator of the present invention is as follows: but under tapping valve is in state of a control between the opening and closing, if do not accept charging in the separator, promptly there is not liquid, the gravity effect of floating drum makes tapping valve shank 12 seal tapping valve outlet 10, this moment, tapping valve was in closed condition, and the material in the separator can not export 10 from tapping valve and discharge.After separator begins continuous feed, gas-liquid two-phase fluid separates in floating drum 8, liquid flows out by floating drum bottom outlet 14 and floating drum bottom side hole 15 bottoms, stockpile at the separator inner bottom part, and gas is overflowed by floating drum bottom side hole 15 tops and left separator by blast pipe 16.Along with charging increases, the liquid that the separator inner bottom part stockpiles is on the increase.Because floating drum side opening 15 does not have bleeder port with top, liquid level can not be higher than the upper limb of floating drum side opening 15 all the time in the floating drum, and makes the liquid level in the floating drum be lower than the outer liquid level of floating drum eventually.Liquid level difference between the inside and outside liquid level of floating drum forms the buoyancy of liquid to floating drum 8, when floating drum 8 suffered buoyancy and himself gravitational equilibrium, just form the switch critical point of tapping valve, at this moment, as the liquid that enters in the separator increases again, move on the outer liquid level of floating drum, floating drum 8 floats thereupon, and interlock tapping valve shank 12 leaves tapping valve outlet 10, tapping valve is in opening, and liquid leaves separator from tapping valve outlet 10.If the liquid inlet of separator is identical with discharge rate, then the outer liquid level of floating drum is constant, is in stable state.If the liquid inlet of separator is greater than discharge rate, then the outer liquid level of floating drum increases, and floating drum 8 floats thereupon, and the tapping valve aperture increases, and the liquid discharge rate increases immediately, and the outer liquid level of floating drum highly is in stable state at another.If the liquid inlet of separator is less than discharge rate, then the outer liquid level of floating drum reduces, and floating drum 8 descends thereupon, and the tapping valve aperture reduces, and the liquid discharge rate reduces immediately.When liquid level outside the floating drum is reduced to floating drum 8 suffered buoyancy when being slightly less than himself gravity, tapping valve just is in closed condition, and the outer liquid level of floating drum no longer descends.Therefore, utilize the equilibrium relation of suffered buoyancy of floating drum and himself gravity, realized that just liquid level of the present invention controls automatically.Because floating drum adopts non-closed structure, no matter the separator internal pressure is much, the inside and outside pressure reduction of floating drum all equates with liquid level difference between the liquid level inside and outside the floating drum, floating drum material therefor and structure thereof can not destroyed by the small pressure reduction inside and outside the floating drum, and therefore the integrated gas-liquid separator of level control of the present invention does not have the working pressure condition restriction.
When escaping gas on the liquid level in the floating drum 8 is enough to keep the poised state of floating drum 8 suffered buoyancy and himself gravity, feed pipe needn't stretch in the floating drum, get final product and place outside the floating drum not have to leak to be connected with the side of separator urceolus 7, as shown in Figure 2, so further simplified structure.
