Definitions
- the invention is directed to a spray tower, in particular for spray drying / spray agglomeration of detergent ingredients or the like, the spray suspension being sprayed against the hot and swirling air in countercurrent in the tower in the direction of gravity via spray nozzles in different nozzle levels, with several nozzles in each nozzle level are arranged on the circumference.
- hot spots can form in the tower during operation. Such hot spots mean a not inconsiderable loss of energy, and they often occur in the center of the spray tower.
- the object of the invention is to optimize the energy used, in particular to avoid such "hot spots”.
- this object is achieved according to the invention in that in at least one nozzle plane on the circumference, spray cones producing nozzles are arranged on spray arms of different lengths, essentially horizontally arranged.
- the spray nozzles arranged on the spray arms form asymmetrical spray cones with respect to the vertical, ie deviate from the known spray cones which point symmetrically vertically downward.
- the ratio between the nozzle arm length (1) and the inside diameter (d) of the spray tower can be varied according to the invention.
- the length of a portion of the spray arms in relation to the inside diameter of the spray tower (INd) can be 0.1 to 0.2, the second ratio used in the same plane (l 2 / d) can be, for example, 0.01 to 0.1 be.
- the corresponding ratios l 3 / d can be 0.2 to 0.4.
- the inner diameter of the spray tower (d) can be 6.5 m, the spray arm lengths then 0.15 m, 0.9 m and 1.4 m with three different spray arm lengths or but with two spray arm lengths 0.15 m and 0.9 m.
- the invention provides a spray cone distribution which differs therefrom because of the spray arms of different lengths.
- the corresponding distribution in one level of the spray tower results from the representations of the spray cone distribution shown below.
- FIG. 1 shows a simplified longitudinal section through a spray tower according to the invention
- FIG. 2 shows a schematic diagram as a top view of the nozzle distribution roughly along line II or Ha in FIG. 1,
- Fig. 5 is a projection of the spray cone of FIG. 4 in the plane of the drawing and in the
- Fig. 6 to 8 distributions of the spray cones in supervision according to arrow II or Ha in Fig. 1 with differently distributed nozzles on differently long nozzle arms.
- the product then falls down in the direction of gravity according to arrows 4, where it encounters hot air and swirl air, the entry of the tangentially supplied swirl air is shown with arrows 5, it can be air of 50 ° C., for example in one embodiment 24,000 m 3 / h can be entered.
- the entry of the hot air is indicated by an arrow 6, for example 110,000 m 3 / h at 280 ° C.
- the exhaust air discharged at the top of the tower is indicated by an arrow 7, the product discharge below by an arrow
- the lower nozzle plane is preferably influenced, but it can also be influenced the upper nozzle plane 3 or intermediate nozzle planes, which are not considered here in the drawing.
- FIGS. 2 ff Has been chosen in a simplified manner, with FIGS. 2 and 3 showing the variation that 2 4 spray arms of different lengths are arranged on the circumference of the spray tower 1 with changing sequence, as an example there are given a diameter of the spray tower of 6.5 m and a total height of 43 m spray arm length of 0.9 and 1.65 m.
- FIG. 6 shows a spray cone arrangement which corresponds approximately to the arrangement according to FIGS. 2 and 3
- FIG. 7 shows images which roughly correspond to the Figures 4 and 5 correspond
- Figure 8 shows another possible arrangement
- the spray arm length can be changed during operation, if necessary, for example by mechanical or hydraulic delivery, in different spray levels different spray arm arrangements can be provided with images of the spray cones which then result differently u.
- the spray arm length can be changed during operation, if necessary, for example by mechanical or hydraulic delivery, in different spray levels different spray arm arrangements can be provided with images of the spray cones which then result differently u.

Abstract
L'invention concerne une tour à priller (1) destinée notamment à sécher par pulvérisation/agglomérer par pulvérisation des constituants de détergents ou similaires. Selon l'invention, des suspensions sont injectées par l'intermédiaire de buses de pulvérisation dans différents plans de buses (2, 3), dans le sens de la force de gravité, dans la tour, à l'encontre de l'air chaud en turbulence (5, 6) acheminé à contre-courant. Plusieurs buses sont disposées en périphérie, dans chaque plan de buses (2, 3). L'invention vise à optimiser l'énergie utilisée et notamment à éviter la formation de </= points chauds >/= . A cet effet, il est prévu de placer dans au moins un plan de buses (2, 3) des buses produisant des cônes de pulvérisation sur la périphérie, sur des bras de pulvérisation (11a, 11b, 11c) de différentes longueurs, disposés sensiblement horizontalement.
