过滤器壳体的清洗方法
摘要：
本发明涉及一种清洗过滤器壳体的方法，特别适用于清洗锅炉过滤器中的未过滤液室，其中，滤烛被固定于将过滤液室与未过滤液室分隔开的中间底板上，而未过滤液室中可被施加清洗用液体。本发明还涉及一种清洗这种过滤器壳体的装置。通过本发明可以能够对这类过滤器的内壁从其顶部开始基本上全部包括地用清洗液体进行清洗。本发明还设置，在未过滤液室的上部区域中，将清洗介质对准中间底板的底壁和/或者是对准未过滤液室的室壁上部区域，它们这样使液流转向，使得一个基本封闭的清洗液膜由未过滤液室的上部室壁处在壁上流下。
摘要（英）：

The invention relates to a method for cleaning filter housings, especially for cleaning the unfiltrate area of boiler filters, wherein filter candles are fixed on an intermediate bottom separating the filtrate area from the unfiltrate area and the unfiltrate area is rinsed with cleaning fluid. The invention also relates to a device for cleaning said filter housings. According to the invention, practically all the inner walls of said filter are rinsed with the cleaning fluid from the upper area downwards. To this end, a cleaning agent is directed in the upper area of the unfiltrate area against the lower wall of the intermediate bottom and/or against the upper area of the wall of the unfiltrate area, the direction of the flow being such that a substantially hermetic cleaning film can be guided down from the upper wall of the unfiltrate area to the latter.
