SPECIFICATION forming part of Letters Patent N o. 7 00,469, dated May 20, 1902.
\ Application filed September 10,1901... S rial No. 74,873. (No model.)
To all whom it may concern:
Be it known that I, JAMES H. BAKER, a citizen of the United States, residing at Saratoga Springs, in the county of Saratoga and State of New York, have invented an Improvement in Blow-OlfNozzles for-Paper-Mill Machinery,
of which the following is a specification.
- In paper-mill machinery the hotpulp passes from the bottom of the pulp-digester to the blow or receiving tank. These blow-tanks have an opening from the top of the tank to the roof or open air,and the hot pulp is largely charged with sulfurous fumes, which escape from the open upper end of the blow-tank and become very objectionable, not only in the immediate vicinity of the blow-tanlgbut often in the surrounding neighborhood.
The object of my invention is toreduce these sulfurous fumes, so as to overcome the aforesaid objection. vention I employ a blow-'otf nozzle and place the same in a line of piping from the bottomof the pulp-digester to the blow or receiving tank, and by means of this nozzle I introduce water into the hot pulp as the same passes from the digester to the tank. The Water mixes with the hot pulp, cools the same, and
takes up the sulfurous matter either in soluthe blow-tank or one end may be connected directly to the pulp-digester and the other end to the line of piping. The upper portion of the cast body is made with a flange and an opening within the same, and I employ a bend passing down into the body having a flange resting upon the aforesaid flange and an orifice that points toward the deliveryopening of the body and toward the line of piping to the blow-tank. This orifice advantageously comesdirectly in the ce'nterof the body. A nipple isconne'cted to the flange of the bend and a supply-pipe for water connected to the nipple. Bolts hold the water- In carrying out my indevices water is admitted through the bend into the center of the cast body and into the center of the moving mass of hot pulp on its way from the digester to the blow-tank. The water may be admitted in any desired quantity and at any required or advantageous pressure. z
.Inthe drawings,.'Figur'e 1 is a sideelevation, partially broken open, illustrating my invention; and Fig. 2 is a vertical cross-sec- .tion of the same. The cast body a preferably tapers toward the ends. I provide a flange 2 at one end, which comes toward the pulp-digester,and at which flange the cast body is either directly connected to the pulp-digester or may be connected in the line of piping extending therefrom to the blow-tank. The cast body at the other end is provided with a flange 3, by which the same is connected to the pipe in the line of piping and which pipe extends to the blowtank. The inlet-opening at the flange 2 is advantageously appreciably smaller than the opening at the flange 3, and on the upper portion of the castbodyI provide aflange 4,having a-flat face and an opening into the body within the flange. The bond 1) passes down through this opening into the body, and the same is tubular, with a flange 5 resting on the flange 4, and the center of the orifice of the bend is advantageously in the axial center of the cast body and the orifice pointedtoward the flange 3 and toward the pipe extending to the blowtank.
I prefer to employ adouble-flanged nipple c, to which the water-pipe 6 is connected in any-desired manner.v The top bolts '7 screw into "the flange-4 and extend through the flange 5 of the bend b and through the adjacent flange of the nipple, and nuts on the bolts 7 hold the said flanges together to firmly 'connect the cast body, the bend, and the nipple, and packings may be interposedbetween these flanges, if desired.
Water to be mixedwith the hot pulp passes through the water pipe, the nipple, and through the bend 11 into the centerofthe cast body, and its direction as it emerges from the bend is the same as that of the moving pulp. It is injected into the center of the mass of hot pulp and mixed thoroughly with the same, the waterand pulp flowing on to the blow-tank. The water absorbs or mechanically takes up the sulfurons matter in the hot pulp and reduces to a minimum the sulfurous fumes that may escape from the open upper end of the blow-tank as the mass of material pours into the tank, the Water performing the double function of cooling the pulp and taking up therefrom the sulfurous matter.
The Water may be drained or otherwise removed from the mass of pulp in the blowtank in any desired manner.
I claim as my invention- 1. A blow-cit nozzle for paper-mill machinery, comprising a cast body adapted to be connected in the line of pipingfrom the pulp-digester to the blow-tank and having an opening in the surface thereof and a bend passing down into the cast body through said opening with the orifice of the bend in the center of the cast body and set toward the blowtank, and means for connecting the bend to the cast body and for connecting to the bend a pipe for supplying water, substantially as set forth.
2. A blow-oif nozzle for paper-mill machinery comprising a cast body having flanged ends and tapered toward the ends with the openings in the ends of different apertures, an opening in the side of the body, and a flange around the opening, a bend passing through said opening and having a flange resting on the latter flange with the orifice of the bend coming at the center of the cast body and opening in the direction toward the larger end of the cast body and toward the pipe extending to the blow-tank, and means for connecting the bend to the cast body and for connecting to the bend a supply-pipe for water, substantially as set forth.
3. A blow-off nozzle forpaper-mill machinery, comprising a cast body having flanged ends and tapered toward the ends with the openings in the ends of diiferent apertures, an opening in the side of the body and a flange around the opening, a bend passing through said opening and having a flange resting on the latter flange with the orifice of the bend coming at the center of the cast body and opening in the direction toward the larger en d of the cast body and toward the pipe extending to the blow-tank, and a double-flanged nipple resting upon the flange of the bend and bolts for connecting the parts together, and a pipe for supplying water to the bend connected to the double-flanged nipple, substantially as set forth.
Signed by me this 0th day of September, 1901.
