Embodiment
The present invention is by water inlet pipe (1), rising pipe (2), No. 1, connecting pipe (3), permanent liquid level water tank (4), No. 1, valve (5), No. 2, connecting pipe (6), No. 2, valve (7), ball-collecter (8), pitching pipe (9), ball injector (10), solenoid valve (11), U-tube (12), tensimeter (13), gas-holder (14), No. 3, connecting pipe (15), compressor (16), No. 4, connecting pipe (17), valve No. 3 (18) and airlifting ball (19) composition, the equal diameters of pitching pipe (9) and U-tube (12) and be slightly greater than airlifting ball (19) diameter, thus airlifting ball (19) can be allowed to move in these two kinds of tubing strings, appropriate airlifting ball (19) is put in pitching pipe (9), the gas that compressor (16) running produces q.s is stored in gas-holder (14) by No. 3, connecting pipe (15), water inlet pipe (1) is to the water delivery of permanent liquid level water tank (4), No. 2, valve (7) is opened after the water of input q.s, the water in permanent liquid level water tank (4) is made to flow into U-tube (12) bottom by No. 2, connecting pipe (6) and accumulate wherein, after a period of time, in U-tube (12), liquid level reaches required standard, the airlifting ball (19) that ball injector (10) controls in pitching pipe (9) drops in ball injector (10), open No. 3, valve (18), after checking that in No. 4, connecting pipe (17), air pressure reaches required standard by tensimeter (13), airlifting ball (19) is launched at ball injector (10) control time interval, and open solenoid valve (11), gas enters ball injector (10) by No. 4, connecting pipe (17), solenoid valve (11) effect here ignites pressure gas when preventing valve No. 3 (18) from opening and control pressure gas more accurately to flow out, afterwards because injecting gas is higher than U-tube (12) interior pressure, gas push airlifting ball (19) is descending at the right tubing string of U-tube (12), then risen by the left tubing string of U-tube (12), and the liquid ordered about in U-tube (12) post rises, now airlifting ball (19) is as the solid interface between liquid phase, achieve stable slug flow state, while gas push airlifting ball (19) and the liquid on airlifting ball (19) rise, effectively prevent liquid to fall after rise, reduce the slippage loss between liquid phase, gas afterwards, fall after airlifting ball (19) and liquid arrive U-tube (12) left tubing string top, liquid flows into No. 1, connecting pipe (3) after falling into ball-collecter (8), open No. 1, valve (5), liquid is flowed in permanent liquid level water tank (4) by No. 1, connecting pipe (3) recycle, gas is then discharged into the atmosphere after entering ball-collecter (8), airlifting ball (19) enters pitching pipe (9) after falling into ball-collecter (8), controlling rising pipe (2) afterwards makes permanent liquid level water tank (4) play a role with water inlet pipe (1), namely the liquid level in U-tube (12) is kept to reach required standard, then circulate said process.
