When there is a trace amount of waste in use, the process pump is pumped down, thereby rendering it inoperable and necessitating a shut down operation to clean the filter.

Please refer to fig. 2 to fig. 4. Only the internal structure of the duct filter is shown in fig. 2. The utility model provides a pipeline filter, including barrel 1, inner wall 4 and a plurality of passageway 5. The inside of barrel 1 is located to inner wall 4, and inner wall 4 includes first grillage 8 and first filter screen 2, and first filter screen 2 locates the both sides of first grillage 8. The plurality of channels 5 are separated by an inner wall 4. The utility model provides a passageway 5 has four, is separated by four inner walls 4 between four passageways 5, and four inner walls 4 are connected in the position of center pin, and two of them inner walls 4 are located the first plane, and wherein two other inner walls are in the second plane, and first plane and second plane can be mutually perpendicular, guarantee that four passageways 5's filter effect is unanimous, but the utility model discloses do not do any restriction to first plane and the planar contained angle of second, can also be other arbitrary angles. The two inner walls 4 on one plane can be integrally formed, and the two inner walls 4 on one plane can also be separately manufactured and formed.

The utility model provides a pipeline filter is used for the T type pipeline in the process flow pump that petrochemical field used more. T-shaped pipeline is more easily plugged up than ordinary linear type pipeline, uses the utility model discloses a pipeline filter's filtration performance is high, can effectively avoid plugging up of T-shaped pipeline. On the basis of the existing simple straight-tube type pipeline filter, the inner wall 4 is added, the basic structure of the original filter is kept, and the replacement of the whole equipment caused by the improvement of the filter is avoided. Besides, the inner wall 4 is arranged on the side wall of the cylinder 1 at the filtering position of the filter, so that the filtering area is increased, the using period of the filter is prolonged, the filtering efficiency of the filter is improved, the switching frequency of the pump can be reduced in the matched use of a process pump to ensure the intrinsic safety of the process, the emission of organic volatile matters caused by the operation of cleaning the filter is greatly reduced, and the on-site labor protection environment is improved.
