lpecmcatlon 0! Letters Patent.
Patented Mar. 23, 1915.
Application filed Kay 15, 1914. Serial I0. 8 38;. v
T all whom it may concern:
Be it known that we, Tnomas E. Menus! and CHARLES B. GRADY, citizens of the United States, residin at New York, in the county of New Yor and State of New York, have invented a certain new and useful Improvement in Apparatus for rapping Particles in Sus ension. in Gas-Currents, of which the fol owing is a specification.
In U. S. Letters Patent No. 1,073,620, granted to myself and Charles B. Grady,
ept. 23, 1913, we have described an apparatus for trapping particles in suspension in gas currents, wherein the incoming current is directed upon a swin 'ng plate, down which is maintained a 0w of liquid, in which liquid said solid particles are engaged. In using this apparatus in actual practice to purify a hot gas current from the flue of a steam boiler, in which apparatus the descending liquid stream is water, we find that the swinging plate, especially if of steel or iron, becomes rapidly attacked and destroyed, this result being apparently due to the chemical union of the gas and water forming a corrosive acid. We have discovered that this difliculty can be prevented by making the plate of wood.
Ordinarily it might be supposed that such a plate would be quickly charred or burned by the boiler gases, but we find this not to be the case, since the water flow sufficiently protects it. Whether from slight carbonization or from the initial attack of the generated acid, the said surface becomes coated with a dark and seemingly refractory film which resists both chemical attack, or the effects of the hot gas current, and the plate lasts indefinitely. We have made such a plate twelve feet long and five feet high, and submitted it to the action of the gas current from one 650 horse power boiler. After four months use, it shows no evidence of deterioration. We have also made another such plate fifty feet long and five feet high, and submittedit to the action of the gas current from a battery of three 650 horse power boilers. After six weeks use, it shows no evidence of deterioration.
In the accompanying drawings we show a sim le form of cinder-tra ping apparatus embo ying our aboverdescribed invention.
Figure is a section on the line :0, a: of F1% 2. Fig. 2 is a section, on the line/ 3 y of 1g. 1, and Fig. 3 is a perspective view of a portion of the swinging plate.
Similar letters of reference indicate like parts.
A is a casin in which is dispose-l the swinging plate which, as above explained, is to be made of wood. We find-cypress wood to be well adapted for the purpose.
C is the inlet opening communicating by flue D with the source of gas current to be purified, which source, not shown, may be a steam boiler.
E is the outlet duct for the purified gas. A body of water F is maintained in the bottom of casing A. A pipe G connected with a source of water supply enters said casing, extends across the upper part of the plate B and is perforated on its lower side so that the incoming water is delivered upon said plate in a plurality of streams. The area of the outlet opening at the bottom of plate B may be varied by means of the cord and hand reel, shown at H, for the purposes fully described in the above named Letters Patent. The hot gas entering from flue D meets the descending water streams on swinging plate B, and proceeding downward is projected upon the water F in the lower part of the casing, where in the solid suspended particles are entrapped. The purified gas escapes from the casing by the outlet duct E.
We claim:
A device of the type set forth for trapping particles in suspension 111 a dry gas current,
comprising a plate of weed, means for de livering liquid upon the surfaceof said plate, and means for delivering the dry gas current to be purified upon said wet surface. In testimony whereof we have afiixcd our signatures in prcsencr of two witnesses,
THOMAS E. MURRAY.- CHARLES B. GRADY.
