UNITED STATES PATENT OFFIC KARL JOHN sUNDsTRoM, OF Rusrrc, NEW JERsEY, ASSIGNOR OF THREE- FOURTHS TO ALFRED DE CASTRO, OF NEW YORK, N. Y.
PAN FOR CONCENTRATiNG SULPHURIC ACID.
SPECIFICATION forming part of Letters Patent No. 349,414, dated September 21, 1886.
Application filed November 21, 1885. Serial No. 183.469. (No model.) I
To all whom it may concern:
Be it known that I, KARL JOHN SUND sTR6M, a citizen of the Kingdom of Sweden, residing at Rustic, in the county of Morris 5 and State of New Jersey, have invented a new and useful Improvement in Pans for Concentrating Sulphuric Acid, of which the follow ing is a specification, reference being had to the accompanying drawings.
This invention consists in the novel combination, hereinafter described and claimed, of
v the concentrating-pan and the cover thereto, which constitutes a cooler for the condensation of the weak acids evaporated in the concentra I 5 tion, whereby the concentration of sulphuric acid from 60 Beaum to a higher strength can be successfully performed by a continuous opera tion. This is illustrated in the accompanying drawings of a pan, and its condensing-cover constructed according to my invention.
Figure 1 in said drawings represents a central vertical section of the pan and its condensing-cover complete,- and Fig. 2 represents a plan of the pan as it appears without the con (lensing-cover.
Similar letters refer to similar parts throughout both views.
A is a cast-iron pan provided with an integral flange, b, in which there is a U shaped channel, f, in which the bottom of the cylindric cooler of lead,c,rests. This cooler has double walls, within which cold water is circulated, and it has at the top a surrounding channel, f within which is placed another double-walled but conic cooler of lead, d, from which the tube H conducts to the lead chambers of a sulphuric- 7 acid works.
I is the leaden pipe, through which the acid to be concentrated is introduced into the pan.
P O designate the pipe of glass, porcelain, or platinum,through which the concentrated acid passes out from the pan.
By controlling the metal pipe I any desirable strength may be obtained of the concentrated 4 5 acid which passes out continuously by the pipe P O. The weak acid proceeding in the form of steam from the boiling sulphuric acid in the pan A is condensed on the interior of the walls of the coolers 001, down which it runs into the channels f f whence it runs out by the pipe 9, the upper channel, f, communicating with the lower one by a pipe, 9.
w w are the pipes for the admission of cooling water to the spaces between the walls of the coolers c d, and u a are the pipes for the escape of the water from said spaces after cooling.
Eis a wall of acid-proof bricks tightly put together around the interior of the flanged rim of the pan A for protecting the iron against the weak acid, from which only it requires protection, the strong or concentrated acid not affecting the iron. The cast-iron flange b and the gutter f within it are protected by a lining, 11, of lead.
I do not claim as my invention an apparatus for concentrating sulphuric acid, consisting of a platinum bottom and a condensing-cover of lead, as such apparatus is described as the in vention of Faure and Kessler, in a work en titled Lunge on Sulphuric Acid, Vol. I, pages 542, et seq.
What I desire to claim and secure by Letters Patent is The combination of the concentrating-pan A, having a surrounding channel, f, the cylindrical cooler 0, having its lower edge resting in the channel f of the pan, and having in its upper part a surrounding channel, f the conic cooler d, having its lower edge resting in the said channel f, and the escape-pipe 9, connecting the said channels f f whereby all-the condensed products collected on the surfaces of the upper and lower coolers are caused to be received ,in the said channel f, substantially as herein described.
