Abstract: 1,170,047. Gas analysis; measuring fluid-flow. BAHCO A.B. March 15, 1968 [March 17, 1967], No. 12808/68. Heading G1B. Apparatus for determining the concentration and distribution of particle size of particulate solid matter suspended in gases flowing in a duct 1 comprises a sampling member 7 having a central through passage wherein are arranged in series two cyclone-type separators with annular collection chambers 16, 24 and a filter 26. The gases enter through a passage 13 in a nozzle 12 and a rotary motion is imparted to the gases by guide vanes 18<SP>1</SP> or an insert 17. Coarse particles in the gas stream enter an annular gap 20 and are collected in the chamber 16. Intermediate size particles enter a further gap 23 and are collected in the chamber 24, and the remaining five particles are retained by the filter 26. Gas flow through the apparatus in spite of the pressure reductions caused by the cyclonetype separators and the filter 26 is maintained by supply of compressed air to a conduit 29 leading to suitable ducting in the body 6. Also contained in the body 6 is a differential pressure flow-meter connected to conduits 47, 48 to measure the flow through the apparatus and this measured valve may be used to control the flow by regulating the compressed air supply to the conduit 29. In use after the apparatus has been in use for a known time so that a known quantity of gas has passed through the apparatus, it is dismantled and the particles collected in the chambers 16, 24 and the filter 26 are weighed. The differential pressure-flow meter, Fig. 2, comprises a plate 35 having an annular gap 37 between its edges and the housing of the apparatus, the gap leading to an annular chamber 38 connected to the conduit 47. A central opening 36 in the plate 35, forming part of the through passage of the apparatus leads to a passage 33. A gap 42 between the opening 36 and passage 33 communicates with an annular chamber 41 and thus with the conduit 48, the differential pressure between the chambers 38, 41 being dependent on the rate of flow of gases through the apparatus.

As shown, the vegetable matter is fed into the chamber 1, Fig. 1, provided at its upper part with apertures 1a and in the bottom with two discharge openings 2 controlled by means of valves. Shafts 3 carrying crushing arms 4 are provided within the chamber and are driven by a motor 5.  Pipes 6 open into its lower part for the admission of steam to maintain the temperature of the mass at 90-100 DEG  C.  The usual reagent is soda leach or lime leach.  After about 30 minutes treatment the mass is dropped into the second part of the apparatus B, comprising two metal or concrete conduits or tunnels 7 substantially horizontal.  A shaft 8 provided with arms 9 is mounted in each conduit.  At one end is an inlet hopper 11 below the valve-controlled outlet of the chamber 1 and at the other end outlets 12 near the top of the conduit.  Material is discharged continuously through these outlets 12 into C, a compressing and separating device. The conduits 7 are heat-insulated to allow the leaching to be completed at a temperature of 90 DEG  to 100 DEG  C.; the volume of the conduits should be approximately ten times that of the chamber 1. The third part of the apparatus, C, is a compressing and separating device.  At least one piston 13, Fig. 3, is mounted on a tube 14 and reciprocates within a hollow body 17 having a cylindrical centre-portion corresponding to the path of travel of the piston, and tapered end-portions.  The tube 14 and end-portions are perforated to permit passage of liquids but not of cellulose fibres.  As the pasty material is discharged from the conduits into the device C, the reciprocating movement of the piston compresses it in the tapering portions, compressed cellulose continuously emerging from the open ends 20.  This material is substantially free from the leach used in its extraction.  The leaches may be recovered and re-used.
