摘要:

排放系统是海上固定平台最重要的系统之一.为防止可燃气在排放管内串通,开式排放管均设有U型管液封装置.由于含砂排放时常规U型管极易堵塞且难于清理,根据液封原理对海上平台U型管液封进行了改进设计,同时设计了新型Y型管液封,更适用于海上平台含砂排放系统.新型Y型管液封装置具有液封和沉砂两个功能,可以有效监测管内沉砂情况,容砂量大,且易于清理.

Abstract:

Drain system is one of the most important systems on offshore platforms. In order to prevent the turbulent flow of combustible gas which comes from different regions, U-tube liquid seal device is often used in open drain pipes. When the drain system contains sand, the U-tube will get clogged frequently and is difficult to clean. To solve this problem, the optimization of U-tube liquid seal device is performed according to the principle of liquid seal. Moreover, a new Y-tube liquid seal device is designed, which is more suitable for drain systems which contain sand on offshore platforms. The Y-tube liquid seal device, with the function of sealing and settling, can easily be cleaned, and provides more advantages than U-tube liquid seal device.

Key words: offshore platform, drain system, U-tube liquid seal device, Y-tube liquid seal device
