" l IMPROVEMENTAIN APPARATUS Fon EVAPORATINGAND co'NcENTRAnNe Lloulns.
Specification forming part of, Letters Patent Nol A112,348,7dated March 7, 1871; antedated March 1, 1871. p
of Essex and State of Massachusetts, have invented certainlmprovements in Apparatus for Evaporating and Concentrating Liquids, of which the following is a specification:
Figure l is a side elevation of my invention. Fig. 3 is a side elevation with a section through line ma", Fig. 2 ;l and Figs. 4 and 5 are sections through lines y y and z z, Fig. 2.
" The object of this invention is to concentrate and evaporateliquids like brine, alum in solution ammonia, &c., for crystallization; and
` it consists of a suitable tank, divided into three compartments, under two of which is a flue or passage communicating with a flue from the smoke-box of a boiler-furnace, while in the other are three or more horizontal pipes, all
connected at the ends by transverse tubes, and receiving steam from a boiler by means of a vsuitable pipe, which steam, after circulating through said tubes, is returned in a condensed form to the boiler.
It also consists of a steamxinjector placed in the iiue from the smoke-box, by means of which the products of. combustion from the furnace are drawn and forced through the passage under :the tank and "mingled with the steam. p
The details of construction and method of operation will be more fully described herein- In the drawing, A represents 'a steam-boiler V over a suitable furnace. B is a shallow tank,
of any suitable material, divided into three compartments, C D E. l
K4 represents a tapering case or flue leading t from the smoke-box of boilerA to the tank B,
and containing one ot my injectors, G, (patented Marchl, 1370,) which latter is supplied with steam fromlthei boiler A by pipe -H and valves L and J. The case orflueK opens into 'a passage, M, under the divisions C D of tank B. Said passage runs directly through tank yB and opens at the opposite end of the same, as
shown at m, Fig. '3.
F F F represent parallel tubes or heaters running along the bottom of division E of tank BL Said Vtubes are of the semi-elliptic shape in cross-section shown in Figs.4 4 andA 5, and
are `connected at their inner ends by the shorter tubes e.v
It represents an induction-pipe leading from the boiler A to the outer ends of pipes F, with which `ends it is connected, as shown in Fig. 5.
. T represents an eduction-pipe leading from the inner end of one of the pipes F to a point in the boiler below the water-mark.
n represents a Siphon-pipe, connecting divisions O and D, and O is a similar pipe, connecting divisions D and E.
Operation.
The iiui'd to be concentrated is placed in a cold state in the division O of tank B, from whence it afterward iiows through-pipe a in to division D. Steam being admitted to injector G through pipe H, it will be forced violently through the flue K andpassage M, thereby exhausting the smoke-box of the boiler and causing the heated products of combustion to rush through the ilue K and passage M around injector K, mingling with the steam and superheating it, and heating the fluid in divisions C D, that in division D receiving the most heat, being nearest the boiler and'furnace.
The fluid. being heated in division D to the utmost capacity of the latter, it is transferred, through pipe O, to the compartment E and on .the pipes F, which are heated by the steam from pipe R. In this division the tempera ture of the iiuid receives its highest degree,
and its volatile portions. are evaporated and the liquid sufficiently concentrated to be drawn oft' for crystallization. v
After the steam from pipe B has circulated through the pipes F and become condensed it is returned through pipe T to the boiler, the pipes F being in all cases above the high-water line.
rlhe use of steam in connection with the heated products of combustion has the important advantage of keeping the surfaces of the iiues and passages through which it passes perfectly clean, preventing the accumulation l of soot, especially when bituminous coal is used.
The injector in all cases keeps up a strong blast without relying on a chimney, except in first starting the iire to get up steam. After this is done the chimney-flue is closed by a y ions C, D, and E, connected by Siphon-pipes u o, heaters F, and pipes R T.
4. The mode of utilizing the condensed steam used to charge the heaters F F by returning the same to the boiler after it has done its work, by the means substantially as described.
5. The mode of employing the waste products of combustion by means of injector K in the partial evaporation of liquids in pans or divisions C and D, and completing the evaporation in the division E by the employment of the balance of steam generated through heaters F, substantially as set forth.
In testimony whereof I have signed my name to this speciication in the presence of two subscribing witnesses.
JOHN HOWARTH.
