IMPROVEMENT IN APPARATUS FOR PURIFYING SALT-BRINE.

Specification forming part of Letters Patent No. 129,397, dated July 16, 1872.

Specification of certain Improvements in Apparatus for Purifying Salt-Brine, invented by LEFFERT R. CORNELL, of Syracuse, in the county of Onondaga and State of New York.

Nature and Object of the Invention.

It is well known to those acquainted with the manufacture of common salt or chloride of sodium that the brine from saline wells generally contains impurities which are deleterious to the salt and embarrassing in the process of manufacture, and various modes have been suggested and improvements devised for the purpose .of removing these impurities, either before or during the evaporation of the brine to produce the salt.

My invention relates to the equalization of currents of air to be forced through the brine, and to the discharge of the steam arising from the brine, by means of an artificial draught and consists in the constructions and devices for that purpose hereinafter described.

Description of the Accompanying Drawing.

Figure 1 is a vertical central longitudinal section of a tank and pipes designed to be the cover being removed.

General Description.

A is a tank or pan to contain the brine to be operated upon, and B is a cover of the same, which is so constructed and attached that it may be removed, if desired. I prefer to make said cover pyramidal, as shown in the drawing, or conical, and I provide it with a flue or chimney, O, at the top, to discharge the steam which arises from the saline water while being operated upon. Said cover is also provided with a door, D, by which access may be had to the pan without removing the entire cover. E is a pipe, designed to be connected at the outer end with a heating apparatus and a blower for heating the air which is to be forced through the brine. F is a large pipe placed at the bottom of the tank A, which pipe F is connected to the pipe E, and also with smaller pipes G G, which latterconnect with the large pipes H H, and have perforations a a in their sides, as shown, to allow the air to be driven through them into the saline water contained in the tank A. The pipes G G are thus supported above the bottom of the tank, so as to be out of the way of the impurities which will settle upon the bottom of the tank. These pipes G G should be of sufficient size, in proportion to the size of the orifice a a, to allow the air to flow freely through them to the pipes H H, and give an equal or nearly equal pressure through all of the apertures a a. It will be obvious that by the combination of the distributing-pipe F, equalizing-pipes H H, and the series of discharge-pipes placed between them, a very perfect and equal discharge of the air through the whole body of the brine is effected, and the distributing and equalizing-pipes, as well as discharge-pipes, being arranged where they will be beneath the surface of the brine, the heat radiated through them from the hot air which they contain is all made to pass into the brine and thus utilize it for its evaporation. I is a pipe which is connected to the pipe E, as shown, and extends upward from it nearly or quite into the chimney G, to furnish a blast of hot air at that point, to aid in carrying off the steam which arises from the saline water in the tank. To avoid the expense of heating this portion of the air the pipe I may be connected directly to the blower or furnished from a separate blower; but this last arrangement might, perhaps, involve the objection that a current of cold air might have a tendency to condense the steam or retard evaporation. For the purpose of supplying the necessary heated air I prefer to employ the blower known in the market as the McKenzie blower, though any good fan-blower or airpump will answer; and for heating the air on its way from the blower to the tank A I prefer'an apparatus such as or similar to that described in the Letters Patent of the United States granted to me for a superheater October 1, 1867. outside atmosphere by the blower and forced through the heating apparatus, where it is properly heated, is forced through the pipe E and thence through the pipes F G G H H and apertures a a into the brine in the tank, sufficient pressure being employed for that purpose to overcome the resistance of the brine to the occupation by the air of the pipes contained in the said brine. I prefer to give the The air being drawn from the Claims.

"I claim as my invention 1. The combination of the tank A, cover B,

opening or chimney G, and pipe I, substantially as hereinbefore set forth.

2. The combination of the tank A, pipe E, pipe F, pipes G G provided with apertures a a, and pipes H H, the whole being constructed and arranged substantially as hereinbefore set forth. 7

3. The combination of the tank A, cover B, opening or chimney G, pipe E, and pipes G G having apertures a a, substantially as hereinbefore set forth.
