从流体过滤污染物的方法、过滤装置和过滤模块
摘要：
本发明涉及从流体过滤污染物的方法，从流体过滤污染物的过滤模块，以及包含至少一个这种过滤模块的过滤装置。在一个实施方案中，公开了从从流体过滤污染物的方法，所述方法包括以下步骤：(1)将含污染物的原料流体(feedstream fluid)导入含至少一个过滤元件(18a)的过滤室(14a)内；使导入所述过滤室内的至少一部分原料流体以以下方向的一种流动：A)顺向流动，其中所述流体以第一方向经过所述过滤元件的壁(22a)；以及B)逆向流动，其中所述流体以第二相反的方向经过所述过滤元件的壁。所述方法还包括：将滤液导出所述室并进入滤液流线(26a)用于收集；随后使导入所述过滤室内的所述原料流体以顺向流动和逆向流动中的另一种流经所述过滤元件，以从所述元件的壁表面除去污染物材料；在通过所述流体以顺向流动和方向流动中的另一种流动除去所述污染物材料后，继续引导使原料流体以所述另一种方向经过所述过滤元件的壁，从而在以所述另一种方向流动期间从所述流体过滤掉污染物；以及之后除去所述污染物材料，将以所述另一种流动方向流经所述过滤元件的壁所产生的滤液导出所述室并导入所述滤液流线用于收集。
摘要（英）：

The invention relates to methods of filtering contaminants from a fluid, to a filter module for filtering contaminants from a fluid, and to a filtration plant comprising at least one such filter module. In one embodiment, a method of filtering contaminants from a fluid is disclosed which comprises the steps of: directing a feedstream of a fluid containing contaminants into a filter chamber (14a) containing at least one filter element (18a); arranging at least part of the feedstream fluid directed into the filter chamber to flow in one of: A) a forward flow direction where the fluid passes in a first direction through a wall (22a) of the filter element; and B) a reverse flow direction where the fluid passes in a second, opposite direction through the wall of the filter element. The method further comprises directing the filtrate out of the chamber and into a filtrate flowline (26) for collection; subsequently arranging the feedstream fluid directed into the filter chamber to flow through said filter element in the other one of the forward and reverse flow directions, to remove contaminant material from a surface of the wall of the element; following removal of said contaminant material by fluid flow in the other one of the forward and reverse flow directions, continuing to direct feedstream fluid through the wall of the filter element in said other direction to thereby filter out contaminants from the fluid during flow in said other direction; and subsequent to removal of said contaminant material, directing the filtrate resulting from flow through the wall of the filter element in said other flow direction out of the chamber and into the filtrate flowline for collection.
