【摘要】：通過(guò)數(shù)值模擬的方法,采用RSM湍流模型對(duì)多管式水力除砂器內(nèi)液-固兩相流場(chǎng)進(jìn)行了研究。研究表明:進(jìn)液室的流場(chǎng)分布、壓力分布影響各單管入口流量及速度分布;除砂器內(nèi)顆粒運(yùn)動(dòng)的軌跡包括儲(chǔ)料室捕集和集液室逃逸;將1000個(gè)顆粒同時(shí)射入除砂器總?cè)肟?跟蹤每個(gè)顆粒得到顆粒的入管比例和分離效率,單管的顆粒入管比例與流量呈正相關(guān),單管分離效率受速度分布影響出現(xiàn)差異;隨著顆粒粒徑增大,從單管分離出的顆粒在儲(chǔ)料罐內(nèi)的沉降速度也增大;綜合各單管的顆粒入管比例和分離效率對(duì)除砂器分離系統(tǒng)的結(jié)構(gòu)提出改進(jìn)方向。
[Abstract]:By means of numerical simulation and RSM turbulence model, the liquid-solid two-phase flow field in a multi-tube hydraulic sand remover is studied. The results show that the flow field distribution and pressure distribution influence the flow rate and velocity distribution at the inlet of each tube. The trajectory of particle movement in the sand remover includes collecting and escaping in the storage chamber, injecting 1000 particles into the total inlet of the sand remover at the same time, tracking each particle to obtain the proportion of the particles entering the pipe and the separation efficiency. There is a positive correlation between the proportion of particles entering the pipe and the flow rate, and the separation efficiency is affected by the velocity distribution, and the settling velocity of the particles separated from the single tube increases with the increase of the particle size. The improvement direction of the structure of sand remover separation system is put forward by synthesizing the ratio of particles into the pipe and the separation efficiency of each single tube.
