Specification of Letters Patent.
Patented Sept. 5, 1905.
Application filed February 2,1904. Serzal No. 191,679.
Be it known that I, HENRY L. Donmrrr, a
citizen of the United States, residingat Madison, Dane county, and State of lv'isconsin, have invented certain new and useful [mr1 1 V y provements in .lar-Iuxtractors. ot whlch the following is a specihcation.
'Crude gas as it passes through the main contains a great number of minute globules or vesicles of tar or oily matter, and some of these may or may not contain a small volume of gas. It is necessary that these tarry ,e'lobules or Vesicles be subjected to a considerable degree of friction, sutlicieut at least to break them up in order that the gas may be liberated and the tar liquefied and deposited. The deposition of the tar cannot be accomplished by merely passing the gas through a series of unains, extensive though they may be, as n. considerable degree of friction is required in order that the tarry globules or vesicles be broken up.
My invention relates to an extractor for doing' this.
Heretofore centrifugal tar-extractors have been used; but these revolve.
In the best form of the presentinvention relating to tar-extractors there are no moving parts what-ever. as such motion is imparted l l l l l l l l l l l l I l to the as as to cause the tarry )articles. niob- I I ules. or vesicles which nave a greater density than the to be immediately forced against the interior surfaces of the apparatus. and thus be subjected and impact.
Not only is it the object of the present invention to remove the tar, which in its pure state is composed entirely of a number of hydrocarbons of varying density, but also to remove any solid matter suspended in or carried by the gas in the shape of impurities.
The present invention consists of certain features of construction and combinations of parts to he hereinafter described and their particularly claimed with re fcrencc to the accompanying drawing, which shows three drsirable forms of the invention, and in which to the necessary friction i l l l l i v r 1 i i L ui' the bottom of it means of suitable valves 1' From the couplings m in extend branch pipes or conduits 1/11. which at their outer ends are connected at By means of the valves 1 w the by-passing of the gasnronnd the columns I] 1/ is controlled. Suitably secured within the ends of the-pipe oare spiders or skeleton franiesf'f", in central sockets of which are inserted coincident with the axis of the pipe or conduit 11 the tul ulur shaft 1 ofthcscrcw 1 This shaft is closed at its upper end and is open at its lower end, where it communicates. by means of brancln's forming :1 tarscal 1", with adischarge-pipe r". The scrmv-blade slants toward the corner. forming invcrtedcone-shaped surfaces over which the liquid may run in all directions toward the renter. and the edge of the blade in contact with the inner cylindrical surface of the pipe or conduit- 1!. Small holes or perforations if are made in the tubular shaft or axis of the screw, so that the tar which is deposited on the blade and the inside surface of the pipe or conduit may after first flowing downto the tube pass through the said holes or perforations and down the interioroftlmtube. .isnilublerilamisfcrmcd behind each hole for the purpose of causing the tar lo dam up, and thus be forced into the holes. is there n ditl'rreutial pressure in the between the top and botlom parts of the screw. :1 small amount of gas will leak into the tube 4 through the holes or perforations y" at the bottom andont of the holes at the top.
The water seal referred to is provided with two waterup: glas es to show the rilill'erent heights of the water in the seal. lint one of the glasses is shown at the right-hand side of the liv'urejtlie other being omitted from the ielt-lnrnd side. for beinga section it isimpossible toshow the left-hand glass. A, pipe he watnrseul is connected at l with the same and is orovidti-d at opposite sides of the said (,Oillllfjblilll with valves i" ()ne vulve -suy is to be conneclcd to water-supply under pressure. while the other valve sci) "is connected to waste.
drawing the ligure"is a view partly in eh-ra- 'iiiOIl and partly in vertical section, its rightnand side being in elevation and its left in vertical section.
Referring to the ligure, the gas-main 1/. has inserted within its length a trap to be hereinafter described, while at opposite sides of the trap and connected with the main are clbow-coupling'sw/ m, which are controlled by l-iy opening valve 5". for instance. the water in the soul can be entirely withdrawn. while by closing said valve and opening the valve /1 the water-level in the sczilcun be increased. The object of the described water seal is to prevent any undue back pres ure of gas in case the pipe should become stopped up, and it therefore forms an automatic Irv-pass.
'lhc described apparatus can be employed either with coal-gas or water-gas plants for ICO the purpose of removing tar and other solid matter in the shape of impurities.
Having thus described my invention and without limiting myself to details or enumerating equivalents other than thoseillustrated,
what I claim as new, and desire to'secure by Letters Patent, is
1. In a tar-extractor, the combination of a gas-conduit, a column or branch pipe connectedthereto, and a screw or helix in the column having a pitch downward and inward forming inverted-cone-shaped surfaces.
2. In a tar-extractor, the combinationof a gas-conduit, a column or branch pipe connected thereto, and a screw or helix in the column provided with a tubular shaft open at the bot tom and having apertures for drawing elf tar, the screw-blade havinga pitch downwardand inward forming in verted cone shaped surfaces.
3. In a tar-extractor, the combination of a gas-conduit, a column or branch pipe connected thereto, and a screw or helix in the column, means for passing the gas around said column, and a water seal for. said by-pass.
4. in a tarextractor, the combination of a gas-conduit, a column or branch pipe connected thereto, a screw or helix in the column, and a tar seal connected to said column.
5. in a tar-extractor, the combination of a gas-conduit, columns or branch pipes con nected thereto, screws or helices in said columns, I
and pipes connecting the lower portions of the columnsforming tar seal.
6. In a tar-extractor, the combination of a gas-conduit, a column or branch pipe connect; ed thereto, spiders or skeleton frames secur'g d in the upper and lower portions of said "Ijlmum, a screw or helix in the column provided with a tubularshaft, supported by said spiders/ and closed at the top and open at the bottom,
-said shaft having apertures in its sides for said shaft having apertures in its sides for 7 drawing oil tar, and the screw-blade having a pitch downward and inward, and means for by-passing the gas round said column.
In testimony whereof I have signed this specification in the presence of two subscribingwitnesses.
