离子交换树脂在设备间转移过程中的磨损试验研究

The experimental study of ion exchange resin wears in the process of transferring between devices

设计加工了1套试验装置来研究树脂在输送过程中的磨损问题。考察树脂在转移过程中管道直径及水流量与树脂磨损的关系,树脂转移100次后测量其磨损量及磨损率,分析影响树脂磨损的因素,认为:树脂在输送过程中,当管径很大时(如Ф100mm),其内含空气,对树脂转移产生干扰,增大了树脂磨损量;当管径小时含空气量较小,在相同水流量下,管径越小,树脂在连接管中就越密集,树脂相互之间摩擦更剧烈,树脂与管壁的接触更频繁,磨损就越严重。在相同的连接管径下,流体流量越大,流速就越大,树脂与连接管管壁碰撞越剧烈,磨损也就越严重。

According to the problem of resin wear in the process of conveying, an experimental device was processed. The relationship between the diameter of pipe in which the resin was transferred, the water flow rate and the wear of resin in the process of transferring was investigated, the wear volume and wear rate after 100 times transferred were measured, and the factors that affected the resin wear were analyzed. It is observed that when the diameter of the pipe is large （such as 4100 ram） in the transportation, the air in the pipe interfered the transfer of the resin, and the amount of resin wear in- creased; when the resin was transferred in a smaller pipe which contained fewer air, in the same flow rate of water, the smaller the connection pipe diameter is, the more crowded the resins are in the con- nection pipe, the friction between each other is more intensive, the contact between resin and pipe wall is more serious, the resin wear is also more obvious. In the same connection pipe diameter, the greater the fluid flow is, the greater the velocity is, the collision between resin and connection pipe wall is more violent, the wear is also more serious.
