Abstract:
The invention relates to a backwash filter having at least two filter chambers which are arranged on a common control housing (3) which accommodates a control element (9) which is operated by a control drive (20) and by means of which the filter chambers can be switched individually from filter operation to backwash operation and vice versa, and having a pressurised gas feedline for the pressurised gas-aided backwash operation. According to the invention, the filter inserts (2) of the filter chambers (1) are immersed into the control housing (3), preferably by a length which corresponds to at least approximately 1/3 to 1/2 of its overall length. In the control housing (3), the medium space (10) is expediently arranged above the filtrate space (11), the filter inserts (2) being immersed into the medium space (10). The slurry blow- off valve (8) and the valve serving for the feeding of the pressurised gas are separated in construction from the control element (9), the slurry blow-off valve (8) preferably being situated in the horizontal position at the foot of the control housing.

본 발명은 밸러스트수 여과장치에 있어서, 필터부를 수용하는 밸러스트수 여과장치 내에 동심원 방향으로 필터엘리먼트를 설치하고 여과장치 하단에서 밸러스트수를 유입시켜 여과장치 내부의 필터엘리먼트를 통과시켜 여과를 수행하면서, 구동부가 여과장치의 하단에 위치한 흡입부를 회전시켜 필터엘리먼트와 연결시키고 차압에 의해 필터 내부의 이물질을 포함한 역세수를 배출하는 밸러스트수 여과장치에 관한 것이다. 특히, 본 발명은 상기 구동부를 하우징의 하부에 위치시켜 하우징 내에 더 많은 필터엘리먼트를 수용하여 밸러스트수 처리에 적합하도록 여과효율을 높이고, 역세수의 배출라인 상에 배압방지탱크를 두어 배출라인 상의 배압이 증가하는 것을 방지하는 것을 특징으로 하는 배압형성을 방지하는 캔들 타입 밸러스트수 여과장치에 관한 것이다.
Abstract:
A monitoring system (10) is disclosed for monitoring the condition of a filter (16) filtering a gas or liquid. Using various sensors, the permeability of the filter is monitored on a continuous basis. A significant increase in permeability, decrease in permeability or rate of change of permeability can lead to an indication of filter failure, such as rupture, leakage, loading and unloading. The system can be monitored by a computer and monitored from a remote location through phone lines and Internet computer systems.
Abstract:
A filtering installation comprises two cartridge filters (34) each containing a filter cartridge (7) formed of an inner filtering element (9) and of an outer filtering element (10). The filtering elements (9 and 10) are separated by a flow channel (13) and are arranged on a housing plate (5). The cartridge filters (34), respectively the filter cartridges (7) are connected in parallel to a feeder channel (35). The flow channel (13) of each filter cartridge (7) opens out in a reflux channel (38). The housing plate (5) is welded to the casing wall (6) by the welding seams (33) and the two parts are rigidly connected. The passage section of the inlet opening (3) is larger than the passage section of the evacuation channel (13). Thereby, it is possible to obtain a hydrostatic pressure up to 10 Kg/cm2, and therefore a liquid flow rate in the order of 250 m3/h.
