摘要
Abstract
The injection characteristics of Venturi scrubber worked in self‐priming mode in containment filter venting system was studied experimentally under different air flows ,liquid levels and system pressures .The results indicate that with the increase of superficial gas velocity in throat ,the static pressure drop of both sides of the suction grows approximately following a parabolic law ,and the injection flow rate injecting into the Venturi scrubber increases linearly .T he effect of liquid level on injection character‐istics relates closely with the relative position to the outlet of the Venturi scrubber . When the liquid level is below the outlet ,the injection flow rate improves significantly with increasing liquid level and presents a partition phenomenon ,and in the low throat velocity ,the increase of liquid level is more effective to improve the injection flow rate . However ,when the liquid level is above the outlet ,it almost has no impact on the injection flow rate . The pressure is another important factor affecting the injection characteristic of self‐priming Venturi scrubber ,w hich is mainly caused by the change on gas density .In the range of 0‐150 kPa ,with the increase of pressure ,the injection flow rate improves greatly and the influence of pressure is more obvious in high throat velocity than in low throat velocity .关键词
