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.

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.
