Description

Separators, particularly for sludge from boiler water, are the subject of the Invention is a separator, especially for sludge from boiler water, with parallel or vertical baffles arranged like rays, between which the to be cleaned Mixture is guided horizontally in a straight direction.

In a known separator of this type, the vertical baffles are sickle-shaped. They form groups of blades that are bent in opposite directions one after the other and through the spaces between them the mixture flow passes through alternating centrifugal force can. The one in each blade group directed only towards one of the two current flanks Centrifugal force should serve to separate heavy components for their removal special drainage channels are arranged on the walls of the sickle rooms. In such The heavy material can only be separated on the raised, curved flank of the mixture flow be discharged, as far as this is at all possible, because such a curved one Current is due to the roughness formed by the gutter walls Wall surfaces so irregularly disturbed and generally swirled that already segregated Parts are caught again and carried away further. This is particularly unfavorable Restlessness in such sickle rooms, in which such channel walls also still on the hollow curved one Flank of the flow are attached. Such a separator must because of its unfavorable Device have very large dimensions in order to be effective at all.

The invention is based on the knowledge that the most economical The establishment of a separator can only be achieved through structural measures, according to which the separation work, separated from the current driving them, simultaneously and the same size on its two flanks is made using the shortest possible Flow path.

Since the shortest route can only be a straight one, we will follow. the Invention sufficient for both flow flanks on vertical flat guide walls spacious vertical axes Compartments or niches arranged that match in pairs and face each other in mirror image. Consequently can move to both flanks of the currents; only those same pairs, contrary to it: rotating secretion eddies of liquid form, which are opposite to each other in pairs touch the flow and therefore only influence it in such a way that their otherwise disturbing the flow irregularly, directed against the flow flanks Forces cancel each other in pairs. This creates the straight middle course the flow secured with the most effective separation, and the cylindrical vortices can continuously allow the heavy cargo to sink undisturbed. By the forced Secreting symmetrical vortex pairs it has become possible to post the separator of the invention to be dimensioned as small as possible with high efficiency.

The segregation niches or compartments are. after passing by Flow completely or only partially open. Downwards they are better known in and of themselves Way against a collecting space for the sinking material open.

In the drawing, the subject matter of the invention is shown in exemplary embodiments basically explained. They show: Fig. I the arrangement of symmetrically distributed simple pairs of niches on both sides of a straight prismatic flow, Fig.2 with a separator equipped with such niche or fan pairs radial wedge flows in the vertical section and Fig. 3 the corresponding horizontal Section or an inner partial view.

Fig.i .-- Between two flat perpendicular parallel walls b are symmetrical to both flanks of the straight flow indicated by an arrow in pairs opposite to each other the same niche with the help of vertical transverse walls c partitioned off. The liquid flows past the niches and creates large ones in them undisturbed vortex rollers that rotate in pairs opposite one another and reversed serve to separate the suspended matter.

Fig. 2 and 3: In the container e of a separation device are jet vertical flat walls b arranged, which niche together with vertical transverse walls c delimit @ which, in pairs of the same size, are opposite each other across the plane of the fluid @: = d in which the oppositely identical cylindrical separating eddies are located, in pairs of the same size. The container has a tube f at the top for entry the one to be cleaned and a pipe 1 for the outlet of the cleaned liquid, further below a pipe connection k for the discharge of the sinking material.

To the desired horizontal flow, the course of which is indicated by arrows is indicated to force in the area of the niches, a lid are g and above below a partition wall lt 'arranged. This is star-shaped in plan, because it consists only of radial niches in the area of the niches that protrude slightly towards the bottom Stripes that are only as wide as the flow path between the niches. Underneath there is a sink and collection area for the heavy cargo.
