"warren CHARLES W. AIKEN, OF BROOKLYN, NEW YORK.
EVAPORATOR.
Application filed April 5,
The main object of my invention is to improve the efliciency of the evaporator and particularly the type commonly termed glycerine evaporator.
In such construct-ions the liquid to be treated is contained in a reservoir in which is submerged a steam-heated drum. It is customary in such devices to admit the steam to the top of the drum. I have discovered that by providing an extension so as to admit steam to the bottom of the drum and deflecting it through small outlets there is a material increase in the amount of evaporation for a given area of heating surface.
Another object is to provide a form of discharge nozzle which may be readily installed in existing apparatus. Another object is to so construct the parts that a completed drum and steam nozzle may be shipped without danger of breaking.
Figure 1 is a vertical section of one form of evaporator embodying the improvements of my invention.
Fig. 2 is a fragmentary sectional view of r the discharge nozzle on a larger scale.
Fig. 3 is a perspective view of one form of discharge nozzle.
Fig. 4 is another view of another form.
he main reservoir may be made up of a series of sections such as 5, 6, 7, and 8 suitably constructed and connected together and provided with the usual inlets, outlets, and inspection openings.
Inside the reservoir near the bottom is mounted a steam drum 9 spaced apart from the inner walls of the reservoir and provided with circulating tubes 10 for the liquid to be treated. Steam is admitted to this drum through a conduit consisting for instance of a series of pipe sections 11, 12, 13, 14c and 15. The latter section constitutes the nozzle which extends down into the center of the drum and has a series of low slots or outlets 16. The lower end of this nozzle 15 is preferably supported in the bottom of the drum 9, for instance by means of a standard 17 while the upper end is secured in the conduit section 14, for instance by means of a flange 18 and packing such as iron cement 19 above the flange 18. There is also preferably a copper calking ring or gasket 20 on the nozzle 15 at the top of the drum. The inside of the nozzle 15 may be provided with lugs such as 21 to facilitate handling it.
A drain pipe 22 is usually provided lead- 1923. Serial No. 629,980.
ing from the lower end of the drum to take away the condensed "steam.
The vapor products are led out of the reservoir through an outlet pipe such as 23 preferably at the top.
It will be noted that the steam nozzle 15 admits the steam to the lower end of the drum so that the lower ends of the circulating pipes 10 are kept hotter than the upper ends. Although this seems to be contrary to the highest rate of circulation of the liquid in the reservoir it nevertheless has been found to produce'more rapid evaporation in a given time for a given heating surface.
y mounting the nozzle within the lower end of the next higher conduit section 14 it is possible to obtain a tight joint irrespective of the exact height of the drum. It is possible therefore to have the nozzle properly supported in the lower part of the drum as well as at the top of the drum without accurately proportioning the nozzle to the height of the drum. I consider it also important to support the lower end of the nozzle as well as the upper end on account of the very great weight which such a structure frequently has (sometimes 400 lbs). I consider however that many other advan tages of my invention may be had by the use of a construction such as shown at 15' in Figure 4; having a flange 18 adapted to be supported on the upper end or head of the steam drum.
I claim:
1. An evaporator comprising, a reservoir for the liquid to be treated, a steam drum in the lower end thereof, a steam conduit connected to the upper head of said drum, a steam nozzle telescopically mounted in the lower end of said conduit and having its discharge end extending into the lower part of said drum, and a support for the dis charge end of said nozzle.
2. An evaporator comprising, a reservoir, a steam drum in the lower part thereof, a steam conduit extending downwardly in said reservoir to the top of said drum, a
nozzle extending from said conduit downwardly into said drum and having lateral closed lower end and discharge orifices arranged around its lower end.
3. An evaporator comprising, a reservoir for the liquid to be treated, a steam drum in the lower end thereof, a steam conduit conneeted to the upper end of said drum and a steam nozzle telescopically mounted in the lower end of said conduit and having a flange at its upper end and its discharge end extending into the lower partof said drum.
4:. An evaporator comprising, a reservoir for the liquid to be treated, a steam drum in the lower end thereof, a steam conduit connected to the upper head of said drum, a steam nozzle telescopically mounted. in the loxver end of said conduit and having a calking flange at its upper end and its discharge end extending into the lower partof comprising a reservoir for the liquid to be treated, a steam drum therein, a steam nozzle-closed at its lower end adjacent the bottom of the drum and having lateral outlets at its lower end, an openwork support for the nozzle interposed between its lower end and the bottom of the drum and a drain located beneath said openwork support,
