摘要/Abstract

摘要： 为了研究配管的结构尺寸对清管器收球装置流场特性的影响,以P6.3MPa DN700/DN600型收球装置为例,对放空管和排污管的结构尺寸进行了数值模拟,分析了清管器运行速度对其流场的影响。结果表明,在收球筒内,清管器停留处左端压力最大,右端压力较减小但易形成漩涡,放空管和排污管内压力最小。与放空管径50 mm相比,管径100 mm时压力、流速及湍流动能较小。随着排污管径增大,压力、流速及湍流动能减小,变化率也减小,管径为150 mm时,较为适宜。随着清管器运行速度增大,压力、速度及湍流动能均增大。

Abstract: To study the influence of piping diameter on the flow field characteristics when pig receiving trap is working, the finite element model of pig receiving trap whose type is P6.3MPa DN700/DN600 was established, and the effects of the diameters changes of vent pipe and blow-off pipe were simulated. The effects caused by the pig running speeds on the flow field of the pig receiving trap were studied. The results show that in the pig receiving trap, there is the maximum pressure in the left side of pig staying and the pressure begins to decrease and easy to form swirls in the right side. It is minimum in the vent pipe and blow-off pipe and. When the vent pipe diameter is 100 mm, the pressure, velocity and turbulence kinetic energy are smaller than that of 50mm. With the increase of the blow-off pipe diameter, the pressure, velocity and turbulence kinetic energy decrease, and the rates of changes decrease at the same. When the blow-off pipe diameter is 150 mm, it is relatively more appropriate. With the increase of the pig running speed, the pressure, velocity and turbulence kinetic energy on the vent pipe and blow-off pipe increase.

Key words: pig receiving trap, flow field analysis, vent pipe, turbulent kinetic energy, pressure
