Specification of Letters iatent.
Patented Feb. as, 191i Application filed March 28, 1910. Serial No.551,851.
'- pertains to make and use the same, reference being had to the accompanying drawings,
andto the letters of reference marked there= 'on, forming part of this specification. I My invention relates to fluid guides for the fluid conveyingv tubes offluid heaters, in which the fluid to be-heated passes through tubes surrounded by steam, and'has for its object the insertion in the inlet ends of the. tubes helix shaped fluid guides which operate to give aspiral or rotary motion-tothe fluid flowing through the tubes. This feature has proven to be particularly advantageous, when such heaters are used for heating cane juice carrying lime and other foreign matter in suspension, as well. as in such heaters used for heating other fluids carrying foreign matter in suspension therein, as the spiral or rotary motion imparted to such fluid while flowing through the tubes, prevents such foreign matter held in suspension therein from settling upon the inner walls of the tubes. This spiral or rotary motion so imparted to the fluid during its traverse through the tubes also tends to exercise a,
scouring action upon the inner, surfaces of the tubes, and prevents scale and other impurities forming thereon. p
The features of my invention are hereinafter fully set forth and explained, and illustrated in the accompanying drawings in which:
Figure 1 shows a longitudinal section of a fluid heater, embodying my invention. Fig. 2 is a detail view showing an enlarged section of one of the tubes, showing my improved spiral fluid guide therein' Fig. 3 is a detail view showing an enlarged end'elevation of the same. I
In these drawings A indicates-the shell of the heateryB an inner'head secured in one end of the shell; B a floating inner headin the opposite end of the shell A, retained .centrally therein by lugs, b; C, C, C, 0 groups of tubes secured in the heads B and B; D D dividing walls between the groups of tubes C C, and C C and extending from the head B; to the outer head E, secured to the end of the shell A; D is adivision wall between the groups ot-tubes' C, C, and C C and extending from the floatin head B to the auxiliary head E, secure thereto; E the outer head secured to the shell A;
-Fthe steam inlet; F" the condensed water outlet; G the fluid inlet, and G the fluid outlet.
In the inlet ends of the tubes C, C, C and C I remo'vably insert helix-shaped fluid guides H, provided at their outer ends with transverse pins h adapted to engage notches (Z in the inlet ends of the tubes C & c., where-:
by the uides H are held flrmly'against rotation, ut may be easily withdrawn from the tubes. For conveniently removing the guidesI-I, I provide holes h therein adapted to be engaged by a suitable hook adapted therefor;
In operation when. the fluid enters the fluid inlet G below the wall 'D, it passes through the tubes G in the direction of the arrows c, and back through the tubes C in the direction of the arrow 0, and is discharged above thewall D, where it enters the tubes 0 passing therethrough in the direction of the arrow 0 above the wall D,
and thence back through the tubes C in the- -direction of the'arrow 0 above the wall D,
and to the outlet G; meanwhile at the entrance of each group of tubes C, C, C and C the fluid has passed over the spiral or helix-shaped guides H and has been given a spiral or rotative motion as it passes through said tubes, which operates to prevent foreign matter heldin suspension'by such fluid fromsettling and adhering to, the tubes.
.Having thus described my invention so 5 as to enable others to Construct and utilize the same what I claim as new and desire to secure by Letters Patent is:
a A fiuld guide for fluid car'ryingvtubes,
comprising substantially a s iral plate 10 adapted to be inserted into the inlet end of said tube, and a cross bar on said guide engaging notches in the end of the tube to prevent the rotation of the guide therein, substantially as set forth.
In testimony whereof I afiii: my signature, 15
in presence of two witnesses.
