Laminar Flow
spray dryer
Spray dryer in which a hot gas and a shower of a solution, suspension or paste are introduced in the upper section of a closed chamber and moved with laminar flow towards the side exit of the gas located in the lower section of the chamber which is prolongued beyond said exit for a certain length.
The present invention relates to an improved dryer of the direct drying or spray type.
This dryer is illustrated in the attached single FIGURE of drawings which is a sectional elevational view.
The known dryers of the above stated type are in general made up of a cylindrical chamber 1 inside which a hot gas circulates under turbulent flow conditions and from whose top falls a shower of finely divided particles obtained for example, by means of spray nozzles 3 fed by a solution, suspension, mud or paste through a solution feed 4 and an air feed 2.
Since the dispersed particles have extremely small dimensions up to 20 micron, they present large surface areas for a given unit weight; hence drying takes place in an extremely short time interval.
However these known dryers present a number of inconveniences, as for example, it is not always possible to achieve perfect contact between the particles and hot gas and it is difficult to obtain uniformly sized particles. In particular the larger sized particles do not dry completely, hence they wet the particles which have already dried, giving rise to lumps and agglomerates and in addition they adhere to the walls of the chamber, or to the depowdering devices, for example cyclones impeding their proper operation.
The dryer of this invention avoids the previously stated inconveniences since it makes it possible to isolate particles which are only partially dried the particles, thus preventing them from disturbing the operation of the dryer.
We have found that to achieve these aims it is necessary for the hot gas, entering through entrance 5 and the shower of particles to move equi-currently in laminar, rather than in turbulent flow, towards the base, and that the exit 6 for the gas, carrying the dried powder in suspension, be located at the side with respect to the chamber 1, and preferably at right angles with respect to the vertical axis of the drying chamber 1, and that the said chamber 1 be extended for a certain distance, in the order of one chamber diameter, below the level of the gas exit point. In addition the gas outlet is preferably connected to the dryer with an ample fitting.
The particles which are not carried over by the gas current, and that is, the heavier ones due to their larger dimension, or due to their higher liquid content, fall in the said terminal area below the gas exit where they are collected by collector 7 without disturbing the drying process. The particles carried over by the gas exiting from the chamber are separated from it by means of the known de-powdering devices.
