Magnetic Dirt Separator Layout for Low-Turbulence Particle Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing magnetic separators for thermal plants are inefficient in separating both ferrous and non-ferrous particles without interrupting fluid circulation, often requiring additional components that increase overall dimensions and complicate installation and operation.
Innovation Solution
A compact magnetic separator design with a separating chamber and a quieting and collecting chamber, featuring a filtering cartridge and a removably embedded magnet, allows for orthogonal inlet and outlet connections, reducing turbulence and enabling effective particle separation and collection without interrupting fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the magnetic bar is extracted periodically to remove ferrous particles, then the ferrous particles can be removed from the separator, but the circulation of thermal fluid must be interrupted and additional check valves are required
Solution Approach 1:
The magnetic bar is made removable from the separator body, allowing it to be extracted for particle removal. The bar can be taken out through a dedicated opening without requiring interruption of fluid circulation or installation of check valves, thus resolving the contradiction between ease of particle removal and operational continuity.
2Reliability
If the magnetic bar extends along almost the entire separating chamber, then the magnetic separator can retain ferrous particles effectively, but the overall dimensions of the separator increase
Solution Approach 1:
The magnetic bar is segmented into multiple sections or modules that can be arranged within the separating chamber. This segmentation allows the magnetic bar to cover the necessary area for effective particle retention while fitting within compact separator dimensions, thus resolving the contradiction between retention effectiveness and overall size.
3Device complexity
If the inlet and outlet connections are aligned diametrically opposite, then the fluid path is simplified, but the overall transverse dimensions of the separator increase
Solution Approach 1:
The inlet and outlet connections are positioned at different heights (vertical dimension) rather than being aligned horizontally. This vertical arrangement allows the fluid path to remain simple while reducing the transverse dimensions of the separator, thus resolving the contradiction between path simplicity and compact footprint.
4Reliability
If the fluid advances very near the magnets, then the magnetic separator can retain particles effectively, but the circulation must be arrested before removing magnets to evacuate detritus
Solution Approach 1:
A collection chamber or reservoir is introduced as an intermediary space between the magnetic retention zone and the evacuation opening. Detritus collected near the magnets is transferred to this intermediate chamber, allowing evacuation to proceed without interrupting the fluid circulation or removing the magnets, thus resolving the contradiction between retention effectiveness and operational convenience.

Function Achieved in This Case

AI summary
A dirt magnetic separator (1) for a fluid of a thermal plant comprises two hollow bodies (2,8) superimposed according to a longitudinal axis X and defining internally a separating chamber (5) and a quieting and collecting chamber (9) provided with an inner collecting surface (11) for ferrous and non-ferrous particles (7a, 7b) that are removed from the fluid (F). On a side wall (3) an inlet connection (12) for the fluid is obtained, extending transversely to the longitudinal axis (X), near an upper zone (13) that is further from the quieting and collecting chamber (9). An outlet connection (14) is provided for the fluid obtained on an upper outlet end wall (4) and extending parallel to the longitudinal axis (X). The inner collecting surface (11) is at a distance (Dx) from the inlet connection (12) so as not to be affected by turbulence and dragging actions of the fluid. Removable magnet means (15) is arranged for attracting and retaining the ferrous particles (7a) on the inner collecting surface (11), far from turbulence and dragging actions of the flow (F) of fluid. In the first hollow body (2) a guide bulkhead (17) is obtained that extends transversely, from a zone (Z1) near the inlet connection (12) so as to close above a part of the separating chamber (5) bounding above a filtering cartridge (6) housed therein, and defining a gap (18) for evacuating the fluid to the outlet connection (14). Between the guide bulkhead (17) and the side wall (3) a passage opening (19) is obtained, which is diametrically opposite the inlet connection (12) and shaped to enable the fluid to pass from the separating chamber (5) to the evacuating gap (18).
