液体收集器主要功能是液体收集与气体再分布。在液体收集器的设计方面主要考虑以下几点因素：
1、缩短液体停留时间，防止液体局部滞留
2、促进气体均匀分布，气体阻力小
3、设计结构：强度大，抗热胀冷缩
4、现场焊接量小
The major function of the liquid collector is collecting the liquid and re-distributing the gas.
The following factors were put into consideration when New Century Group conducted the designing of the liquid collector:
1．Shortenthe time for the liquid's stay and prevent the holdup of liquid at certain places
2．Promote the homogenous distrlbutlon of gas，and gas resistance shall be small.
3．Designed structure：high strength and prevent the expansion and extraction caused by heat and coldness．
4．Small site welding work．
根据以上设计思想，收集器一般采用如下设计形式：
1、采用条形升气孔，开孔率较大，气体阻力较小，
同时易于现场安装；
2、主槽抽出设计，减小液体的停留时间，防止液体结焦；
3、支槽向中心倾斜，促进液体流动，消除液体滞留；
4、结构合理，抗气体冲击，抗热胀冷缩。
According to the above-mentioned designing guideline,the collector generally takes the following designs:
1．Bar-shaped gas-lifting holes are adopted，which increase the number of holes and reduces the gas resistance．It is
easy to be mounted at site．
2．The main tank is designed in a way that it can be extracted，which reduces the time forthe liquid to stay and prevents
the
liquid coking．
3．The branch tank leans toward the center，which promotes the floe of liquid and prevents the holdup of liquid．
4．The structure is reasonable and prevents the gas impacts and the expansion and extracts under heat and coldness．
