To aZZ whom it may concern:
Be it known that I, GEORGE H. TOMLIN- son, a subject of the Kingof England, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Apparatus for Treating Lignocellulose for Recovering 'lurpentine and Sugar, of which the following is a specification.
My invention relates to improvements in means for treating ligno-oellulose for the recovery of turpentine and fermentable sugar,and is illustrated in one form in the accompanyingdrawing which shows a dia-' grammatic elevation in part section.
The digester A which is rotatably mounted on the trunnions A in the bearings A is driven by the worm A and wheel A and contains the axially located perforated pipe 20 A? which is closed at one endby the blind flange A, passes out of the digester through the stufling box A and communicates by means of the pipe A and supply valve A with any suitable'source of steam supply not shown. The pressure gage A is com nccted by means of the pipe A with the pipe A The pipe B which is closed at one end by the blind flange A has the upwardly extending perforated branch 13 within the digestcr and connects at its outer end with the pipe B which is controlled by the exhaust valve l3" and leads to the condenser B The by-passB controlled by the safety pop valve B leads from the pipe B on one side of the valve B back to the pipe on the other side. ater is supplied to the condenser bythe pipe C controlled by the valve C and discharged therefrom by the pipe G The condensation products are discharged from the condenser through the pipe C to the separator C which extracts the turpentine. The sawdust or ligno--cellulose which is to beused is stored in the bin or hopper D and discharged therefrom into the digcster through the man-hole D being controlled; by the valve D It will be evident that while I have shown in my drawing an operative device still many changes might be made in size, shape and 'arrangement of the parts without deinvntion, and I wish, therefore that my matic.
The use and operation of my invention are as follows :-ln using my apparatus the di" gcster is charged with finely coimninuted ligno-cellulosc such as saw dust which may be acidulated either before or after being placed therein. The manhole is closed, and steam is allowed to enter, displacing the air which passes out through the exhaust valve. The entrance of steam continues after the complete expulsion of air, and as the temperature rises hydrocarbon vapor passes off with some of the steann to the condenser where it is condensed and discharged in the form of a liquid made up of water and the hydrocarbon. From this fluid, the hydrocarbon is separated out in any one of the usual manners. After the digester and its contents have been thoroughly heated by the free steam, the'discharge valve Is closed and the pressure and temperature in the digester allowed to rise, being controlled by the pop safety valve,'until the point desired for the conversion of wood to sugar has been reached. This temperature and pressure is held for the correct time and the digester is then allowed to exhaust into-the condenser,
and the remainder of the hydrocarbon is there recovered. In case sulfuric acid is used as the hydrolyzing agent, the turpentine may undergo partial or complete con version to cymcne or analogous hydrocarbons. The mass left in the digester is then removed therefrom and prepared for treatment in the diffusion battery where it is treated forv the recovery of the sugar which tile products, a valved conduit between said digester and condenser, a by-pass around said valve and a relief valvei-n said bypass.
2. Apparatus for treating ligno-cellulose or the like, comp-rising a digester mounted for rotation, means for introducing steam thereinto and withdrawing vapors therefrom without interrupting its rotation, a
lt t
condenser for volatile products, a valved conduit between said digester and condenser, 21 by-pass around said valve and a relief valve in mid by-pass.
Appamtus for treating ligno-eeliulose or the like, com, aing a for rotation, a fixed pipe or conduit extending'axially thereihrough and having noneommumcating perforate and imperfomtedigester mounted.
seetionsga steanvsupply connection to the 1;,
perforate section, and an eduetion pipe extending info the vapo'espaee of The digeszer and connnunieating with the section.
