Film SPRAY NOZZLEFOR P'Lu mzEn BED APPARATUS REEERENCE TO RELATED APPLICATION This is a continuation of application Serial No. l52,888 filed June l4. 1971, now abandoned BACKGROUND OF THE INVENTION A nozzle inserted into or above a fluidized bed will have lumps of melted 'or-otherwise aggregated material form or cake on it. These large lumps will fall from the nozzle to clog the product removal openings andrender the apparatus inoperative until cleaned; The nozzle of this lnventlon reduces the possibility of material collecting on it to'l'orm large lumps and it better distributes a spray.
BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a longitudinal. vertical section through a fluidized bed apparatus showing a nozzle according to this invention disposed therein; and
FIG. 2 is a transverse section through the nozzle of this invention taken on line 2-2 of FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT As shown in FIG. 1. a blower l forcesair through duet ll to the gas fired heater [2 from which hot gases pass through duct-l3 to the base 14 of chamber 15. The hot gases'pass upward through the perforated plate 16 to fluidize materialin fluidized bed 17.
'i The nozzle of this invention, designated by the reference numeral'20, enters chamber [Sand has a feed solution introduced therein through-fitting 21. As may be seen in FIG. 2, nozzle 20 is'a" length of pipe or tube 21 having" perforations 22 spaced alongitslower portion. A sharp peaked cover 2 3v is'welded at 24 and"25 to extend'over pipe 21. The cover 23'may be made from sheet'rnetal. Any particles that contact the steep sides 27 of cover 23 will roll oil it and thus not build up into large undesirable lumps which could clog the product removal pipe 30 or the screw 31.
The, perforations 22 canbe placed to distribute a solution; laterally from nozzle-20 to. any extent desired.

Claims (1)
