Application filed March 28, 1925. Serial No. 19,016.
esses it is necessary to heat liquors of a corrosive or caustic nature or of an acid nature or content. It is often desirable that this heating take place under pressure. For instance, in the paper and pulp industry caustic soda, lime and magnesia and various salts are used to digest or cook the raw material, removing intercellular matter andv freeing the fibres to be utilized. This material is subjected to high temperature under high pressures. The common practice has been to inject live steam into the mixture, which dilutes the liquor to be recovered which necessitates a higher concentration of chemicals, due to this dilution, to do the work required to the detriment of the fibre strength. This common practice has been occasioned by the fact that there has been no.
practical heating device as the conditions under which it must operate are very severe and extremely destructive.
One of the objects of this invention is to provide a heating device for liquors of a corrosive character or caustic or acid nature. Another object is to provide a heater in which the liquids'to be heatedwill not leak into the heating medium. Still another er that will be eflicient in the operation, par,- ticularly with minimum losses of temperature, ressure and velocity.
A urther object is ,to provide a device of long life and one in which any part thereof is readily replaceable.
Referring to the drawings:
Figure 1, is a longitudinal sectional view of a device embodying the principles of my invention.
Figure 2, is a front view of the device showing the head.
Figure 3, is a view of tube plate 3 removed from the device. I
Figure 4, is a .view of a modified form of device embodying the principles of my invention.
In carrying voutmy invention I propose to provide a device wherein the, component parts have freedom of individual expansion and wherein the flow of the liquid is not impeded by impact losses with consequent loss of efliciency. The conditions of high temperature,relatively high pressure and relatively great velocity make it extremely imtween head 6 and tube plate 3 are machined object of this invention is to providea heatand asbestos metallic gaskets 8 are used.
portant that the dynamic impact losses b obvlated since the effect-of these are to destroy in a relatively short time any device wherein they prevail. I therefore propose to provide a cylindrical metallic shell 1, havc0 ing tubes-2 therein through which the liquor is forced These tubes, in a the preferred embodiment thereof (Figure 1), are secured to tube plate-3,by.having the rolled ends of tubes 2'inserted through openings in plate 3 and welding the ends to plate 3. Tubes 2 are preferably closed at one end, in other words U shaped, so that only one tube plate is required and the tubes 2 are free to expand and contract. The curvature of the closed ends of tubes2 should be of such. a diameter as to permit of the change of di rection of the flow of the liquorrwithout losses. ,Internally secured to shell 1 are supports'31 upon which rest tubes 2. Tubes '2, however, are not fastened to supports '31 but are free to expand. i
The tube plate 3 has a flange 4 which has an exteriorly machined surface to fit within shell 1 to which it is; riveted b rivets 5.
be calked. A head 6 is bolted, onto'tube plate 3 by means of bo1ts6. In order to I have tight joints the seating surfaces 7 bejacent pipe of tubes 2. The curved walls 10 of compartments 9 is of such design as to merely change the direction of flow without creatin' dynamic impact losses. In order Q to provide proper strengthening for head 6,
ribs 11 are cast integral therewith.
The other end of shell/1 has ring 18 secured thereto by rivets 19, the contacting surfaces are machined and calked to provide a tight joint. Ring 18 carries cover plate 20 to which it is secured by bolts 20'. The
bearing surfaces between cover plate 20 and rin 18 are likewise machined and ametallic gas et is used to make the joint steam-tight.
Modifications in detail may be made in my device and still fall within the scope of my invention.
I have shown one such modification wherein the chambers 9' are formed by blocks that 13 and 16 are opened I can be inserted in the header 6 and are not integral therewith. I have i also shown a form of bafliing 32, 33, to distribute the steam more uniformly throughout -the lengths ofthe coils.-
What I claim is 1. A heater comprising a shell, a header,
tubes. within said shell to conduct the medium to be heated, the ends of said tubes connected with said header, replaceable blocks within said-header, said blocks forming chambers in said header, the walls of said chambers being curved to change the direction of flow of the medium to be heated from one tube to the next adjacent tube.
2. A heater comprising a shell, a header, a tube plate, replaceable blocks in said header forming chambers with curved walls, a series of rows of tubes connected to said tube late to conduct the medium to be lieate said chambers of said replaceable blocks cooperating withsaid tubes'to change the direction of flow from one series of tubes to another series of tubes without impact losses. v
Signed at New York, in the county of New York and State of New York, this 18th day of March, A. D. 1925.
