FREDERICK TSGHUIDY, OF FAIBFIELID, ALABAMA.
ACID-SPRAY GATGI-IER.
Specification of Letters Patent.
Patented Apr. 13, 1915.
Application filed September 21, 1914;. Serial No. 862,882.
To all whom it may concern 3e it known that I, FREDERICK TSCI-IUDY, a citizen of the United States, and resident of Fairfield, in the county of Jefferson and State of Alabama, have invented certain new and useful Improvements in Acid- Spray Catchers, of which the following is a specification.
The invention relates to an acid spray catcher designed to prevent acid being carried from a saturating bath by force of the gases and currents emerging therefrom.
In the production of salts, sulfates, sulfids and the like by passing gases or vapors through acid solutions, it is frequently found that the apparatus or pipe systems through which the gases are forced after the saturation process suffer and deteriorate from the action of particles of acid carried along with the etliuent from the acid bath. Very often very expensive pipe systems have to be renewed, not only in the direct vicinity of the saturating apparatus, but also at distant places of distribution of the gas or vapors. To guard against this various means have been employed, but all require a frequent washing which is accomplished by spraying water over the sides and walls or partitions of the apparatus, draining the water off at the bottom of the apparatus. As this washing has to be repeated several times each day without a chance of stopping the operation of the saturating apparatus, it has been found that the velocity of the gases or vapors passing through the spray catcher during the period of washing does not only carry along a certain amount of moisture from the water taken up by the hotter gases but they actually carry along a certain amount of the acid deposits being liberated during the washing process, causing deterioration by such deposits lodging in the pipe system.
The object of the invention is to permit the removal of acid deposits in the acid spray catcher by washing without giving the gases a chance to carry along either moisture or acid and without interfering with the regular operation of the saturator.
The invention will be more readily understood by reference to the accompanying drawings, wherein,
Figure 1 is an elevation of an acid spray catcher constructed in accordance with my invention, and, Fig. 2 is a horizontal section through the construction shown in Fig. 1.
second concentric shell 16, extending from top to bottom of the shell 10. The space within the shell 10, is divided into two compartments by means of walls 18, 19, which are connected to the interior of the shell 10.
Baffles 20, project inwardly from the shell 10, and similar bafiies 21, project outwardly from the shell 16. A partition 22, extends across the shell 16 and divides the same into two compartments each of which communicates with the outlet 17. The space at each side of the wall 22, is in communication with the space inside of the shell 10, by means of ports 23, formed in the walls of the shell 16. Each of the compartments formed in the shell 10, is in communication with the seal pot by means of pipes 13*, which project below the surface of the liquid in said seal pot. The gas to be treated reaches the spray catcher through one or the other of pipes 2 1, 25, each provided with a valve 26,; 27.
In operation the gas is directed to one or both portions of the spray catcher and is forced to follow a tortuous passage therethrough. The force of the gas against the intercepting baffles 20, 21 impinges the heavier globules of acid thereagainst, the acid dripping down into the seal pot 13. The gases then flow through the ports 23, thence into the main 17. When the spray catcher is to be washed one of the valves 26, 27, is closed and water is sprayed into the closed compartment through the spray pipes 28, the gases meanwhile passing through the other section of the catcher. Thus there is no interruption in the action of spraying the acid from the gas. The action of closing off one-half of the catcher leaves the closed side under static'pressure and therefore does not permit the gas to carry ofi either moisture or particles of previously deposited acid.-
Iclaim:
1. In an acid spray catcher, the c0mbina tion of a shell divided into a plurality of iii) compartments, an outlet conduit within said shell, said conduit likewise being provided with a plurality of compartments, each thereof communicating with a compartment of said shell, a seal pot beneath said shell, and means for directing gas to one of nately on the outside and inside walls, substantially as described.
3. An acid spray catcher, comprising an outside and inside shell, divided by division walls into two compartments, each with inlet nozzle and outlet ports, and alternately arranged balile plates, and a diaphragm placed in the inside shell dividing same into two separate chambers each connnunicating with one compartment previously referred 25 to, substantially as described.
