查询词典 solvent

Upside-down taper extracting tank is very beneficial to the circulative extraction from downwards to upward, through the water dividing board and sieve specially designed at the tank bottom, the extracted solvent can make upward movement evenly from the tank bottom. As the tank volume gradually decreases from the tank bottom to the tank top, the short circuit during the flow of solvent can be avoided. Upside-down taper extracting tank is the ideal upgraded equipment for the technology requiring the realization of dynamic extraction processing.

倒锥型提取罐对溶剂的循环提取极为有利，当提取溶剂从上到下循环提取时，通过罐底专门设计的分水板和筛网，提取溶剂能够均匀地从罐底部向上运动，而且由于从罐底部向灌顶部逐渐缩小，所以能很好的避免溶剂流动时短路现象，对于需要实现动态提取加工的工艺而言，倒锥型提取罐是极为理想的升级换代设备。
