(61. 261-98) Stage tower washers which are generally circular in cross-section for the interaction between gases or vapors and fluids are subdivided into a plurality of superposed treatment spaces provided with scrubbing or filling bodies through which the fluid flows downwardly while the gases flow upwardly. In these constructions between the respective superposed treatment spaces at a spaced and separated.

distance from one another there has been provided a supporting plate or bottom for the insertion containing the scrubbing or filling bodies, a collecting bottom for the fluid discharged from the filling bodies and a plate or bottom for distributing such fluid to a-subsequent insertion' or a similar device. In such a construction each bottom or plate for the above purposes required a construction having an associated bearing capable of resisting any bending- Also, due to such an arrangement the treatment space containing the filling bodies suffered a considerable loss in height. It is an object of this invention to provide a construction eliminating the above disadvantages.

It has been suggested in order to decrease the space between the individual plates or bottoms to support the bottom 'for the filling bodies by means 'of spacers positioned upon the bubble tray or plate. However, in this case also the bottom carrying the filling bodies had to have a suflicient resistance to counteract bending. It is a further object of the invention to eliminate the above disadvantage.

A further object of the invention is to provide a washer plate or bottom "for tower stage washers wherein the supporting plate for the scrubbing or filling bodies insertion, the collecting plate or bottom and the distributing plate or bottom for the fluid constitute a single unitary bottom or plate which will eliminate the aforesaid disadvantages.

With the above and other objects in view which will become apparent from the detailed description below some preferred embodiments are shown in the drawings in which:

FIGURE 1 is a diagrammatic vertical cross-sectional view taken on section line l1 of FIGURE 2 through a bottom or plate;

FIGURE 2 is a diagrammatic view of a horizontal sectional view taken along section line 2--2 of FIGURE 1;

FIGURE 3 is a diagrannnatic vertical cross-sectional view taken along section line 3-3 of FIGURE 2 and,

FIGURE 4 is a diagrammatic vertical cross-sectional view showing a modified construction.

Referring to FIGURES 1, 2 and 3 the unitary construction embodying a supporting bottom, a collecting bottom and a distributing bottom comprises a ring 1 of channel construction supported by the annular supporting ring 8 fixed to the interior wall of the tower. Mounted upon the ring 1 in any desired way are a plurality of hollow beams 2 which extend parallel to a diameter of the tower and are spaced a small lateral distance from one another.

These beams 2 are partially in open connection with the The channel or ring conduit 1 is open towards the top and is closed at the bottom. The hollow beams 2 are also open towards the top and closed towards the bottom by the horizontal partition walls 4. The partition walls 4 located in the hollow beams 2 and the conduit l form the conduits 5 in the beams 2 which are open towards the top below the grate 3 and thereby form the collecting bottom or plate for the washing stage. Below the con duits 5 are the conduits 6 which constitute the distributing bottom or plate for the washing stage. The grate 3 as mentioned above, constitutes the supporting bottom for the filling bodies insertion in the space 7 and is supported by the channel ring 1 and the beams 2 upon the supporting ring 8. The collecting bottom and the distributing bottom from the construction above described are also supported by the angle ring 8.

Below the plate above described is the space 9 wherein the filling bodies for the next lower stage are positioned. The gases penetrating the filling bodies insertion 9 flow upwardly through the spaces 10 located between the hollow beams 2 and then through the grate 3 into the inse-rtion 7.

The fluid leaving the filling bodies insertion 7 passes downwardly through the grate 3 and collects in the upper portion'of the ring conduit 1 as well as in the conduits 5 of the hollow beams 2." From here it is led by the ring conduit 11, see FIGURE 2, which extends over a partial length of the ring conduit 1 to the fluid outlet 12. The fluid accumulating here may now be pumped to the next higher located bottom or plate in order to pass it again through the treatment space 7. Itenters the bottom or plate through the fluid inlet 13 into the main supply 14 which is formed by the partition wall 4 in the ring conduit 1. The conduit 14 extends over the ring conduit 1 for such a length that it may connect with all the distributing conduits 6 which are open towards the conduit 14. The conduit 14 is closed at both ends by the vertical Walls 14a. The conduits 6 are closed at their ends 15 which are located opposite to the conduit 14. The outlet of the fluid towards the filling bodies insertion is accomplished by nozzle like openings 16 which are dispersed over the entire length of the conduit 6 at the bottom thereof whereby the individual fluid jets may impinge on the spraying discs 17, as particularly shown in FIGURES 1 and 3.

The distributing bottom comprising the fluid supply conduits 6 are enclosed on all sides by means of the partition walls 4. Because of this, particularly when a fluid circulating pump is used it is possible to maintain the fluid here under a higher pressure than is customary with the 'usual hydrostatic pressure. Because of this the individual fluid jets impinging on the spraying discs 17 are subjected to a greater force and this improves the fluid distribution on the

filling bodies insertion

7 or 9. The necessary smaller cross-section for the pressure-conduits 6 in contrast to the cross-section of the head conduits Sis made possible by a tapering of the hollow beams 2 downwardly and this tapering is advantageous at the same time for the passage of the rising gases or vapors between the beams 2. Furthermore, the proportioning of the cross-section of the two conduits 5 and 6 which are superposed can be influenced by the determination of the position of the partition wall 4.

The fluid accumulating in the ring conduit 11 can, however, as a modification only be led with hydrostatic pressure on the same bottom to the distributing device. For this, the two ends of the ring conduit 14 remain opened. The fluid outlet 12 as well as the fluid inlet 13 become superfluous. The accumulating fluid in ring conduit 11 passes on the same conduit level to the ring conduit 14, from where it distributes into the conduits 6.

A further modification is shown in FIGURE 4. In this form of the invention the fluid supply conduits 14' and 6' are formed as pipes of circular cross-section which are resistant to compression. The fluid supply conduit 14' is annular and extends around the entire circumference of the plate while the distributing conduit 6 of the beams 2 have an open connection at both ends with the conduit 14. The annular supply conduit 14 is provided with an exterior flange 18 which is supported upon the annular angle iron 3' secured to the interior wall of the tower. The grate is shown at 3' resting upon the top of the beams 2 and an interior annular flange 19 fixed to the inner circumference of the supply conduit 14'. The dis tributing conduits 6 are provided at their lower surface with spaced apertures through which the fluid may be discharged as shown by the arrows 20. Above the distributing conduits 6 are located the collecting conduits and the filling bodies insertion above the plate are diagrammatically indicated at 7 while the insertion below the plate is indicated at 9'. The outlet for the fluid is shown at 12' and the inlet is shown at 13'.

With the construction shown in this modification the supply of fluid may be accomplished under high pressure and the conduits 6' are formed as supplying pipes for the distribution of the fluid to the filling bodies below the plate.

The passage through the grate plane 3 located above the spaces for the passage of the gas have to be so proportioned relative to the entire plate or to the crosssectional area of the tower that the amount of fluid flowing through the gas passageslll' to the next lower located filling bodies insertion 9' corresponds to about the amount of fluid flowing over each bottom.

By the combination of the supporting body such as 3', the collecting bottom such as the channels 5 and 11 and the distributing bottom formed by the passages 6", the space between the filling bodies insertions may be kept much lower and therefore the constructional height of the tower washer may be better utilized or in order to secure the same capacity as in tower washers at present in use may be essentially diminished. Also the combination of the collecting bottom and the distributing bottom into the hollow beams 2 and 2' results in a greater height of such hollow beams and thereby secures an increased cross-section of the moment of inertia so that the entire bottom or plate carrying the filling body insertions remains resistant to bending even with a reduced Wall thickness thereby reducing the specific weight of the bottom or plate.

It is thought that the invention and its advantages will be understood from the foregoing description and it is apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing its material advantages, the forms hereinbefore described and illustrated in the drawings being merely preferred embodiments thereof.
