本発明は、木粉、パルプ等の高濃度スラリーを、加水分

スラリーの供給方法及びその装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a slurry supply method and apparatus for supplying a high-concentration slurry of wood flour, pulp, etc. to a high-pressure vessel such as a hydrolysis reactor or a digester.

きたが、エキストルーダ−はマテリアルシールを行うた
め、原料を強く圧縮する部分が必要となるので、この摩
擦抵抗が大きく、強力な動力を必要とし、電力消費が大
きいという問題がある。Conventionally, slurry with a concentration of 10 to 30%, such as pulp, is processed using a hydrolysis reactor, usually 15 to 30 W.
Powerful twin-shaft extruders and long-stroke extrusion pumps have been used to supply the material to J's high-pressure equipment, but the extruder seals the material and requires a part that strongly compresses the raw material. The problem is that this frictional resistance is large, and strong power is required, resulting in large power consumption.
一方、押し出しポンプ方式は、そのポンプ内に高濃度ス
ラリーをつめ込むため、特殊な供給装置を必要とし、さ

、電力消費も大きいという問題がある。On the other hand, the extrusion pump method requires a special supply device to fill the pump with highly concentrated slurry, and also requires two or more sets of extrusion pumps to maintain a constant supply. However, there are problems in that it requires complicated mechanical equipment and consumes a large amount of power.
また、前記三方式はいずれも、供給部に加わる力は反応
圧力Ｘ供給部の断面積となるので、装置のスケールアッ
プに限度がある。Furthermore, in all of the three methods described above, the force applied to the supply section is equal to the reaction pressure x the cross-sectional area of the supply section, so there is a limit to the scale-up of the apparatus.
そこで、本発明は前記従来の問題点を解消するためにな

することが好ましい。That is, the slurry supply method of the present invention is characterized by performing solid-liquid separation in the high pressure section when supplying the slurry to the high pressure container, and the slurry supply device is a high pressure container Hesla IJ- In slurry equipment that supplies
It is characterized in that the high-pressure part is equipped with a solid-liquid separator, and in this case, it is preferable that the solid-liquid separator is equipped with a forced transfer device.

ラリー供給装置であり、第２図は本発明の実施例２にお
ける強制移送装置を装備したスラリー供給装置である。The present invention will be described in detail below with reference to the drawings. FIG. 1 shows a slurry supply device without a forced transfer device in Embodiment 1 of the present invention, and FIG. 2 shows a slurry supply device in Embodiment 2 of the present invention. This is a slurry supply device equipped with a forced transfer device.

い。Here, the forced transfer device 6 in FIG. 2 assists in moving the slurry when it is concentrated to a high concentration, and removes stuck raw materials when handling raw materials that tend to stick to the filter 6 of the solid-liquid separator. Good to use when you need to scrape.
次に、第３図はスラリー供給装置９を高圧容器である高
圧反応装置１１に接続した場合の７０−シートである。Next, FIG. 3 shows a 70-sheet when the slurry supply device 9 is connected to the high pressure reactor 11 which is a high pressure container.
まず、原料スラリーはスラリー貯槽７に貯められ、スラ
リーポンプ８でスラリー供給装置９へ送られる。First, raw material slurry is stored in a slurry storage tank 7 and sent to a slurry supply device 9 by a slurry pump 8.
ここで排出されたｒ液は、沢液弁１０で排出量ならびに
ｒ液室４の圧力をコントロールされてスラリー貯槽７へ
戻される。The r-liquid discharged here is returned to the slurry storage tank 7 while the discharge amount and the pressure of the r-liquid chamber 4 are controlled by a sap valve 10.
一方、スラリーは沢液が排出することによって濃縮され

によって排出量をコントロールされて排出される。On the other hand, the slurry is concentrated by discharging the slurry and is supplied to the high-pressure reactor 11, and the reactant is transferred to the discharge valve 12.
The amount of emissions is controlled and emitted.

点がある。Here, in the conventional method, high concentration slurry was directly supplied to the (3) J high pressure section, whereas in the present invention,
Low-concentration slurry with good fluidity, usually 1 to 5%, is supplied to the high-pressure section using a normal slurry pump, and the slurry is concentrated using a solid-liquid separator in the high-pressure section. It has the advantage that it does not require compression for material sealing and consumes very little power.
また、固液分離装置は、通常フィルターだけで充分であ
るが、フィルター面に固着しやすい物質を扱う場合には
、簡単なかき取り装置を兼ねた、強制移送装置を取付け
ることによって充分その目的をはだすことができる。In addition, for solid-liquid separators, a filter alone is usually sufficient, but when handling substances that tend to stick to the filter surface, it is sufficient to install a forced transfer device that also serves as a simple scraping device. Can be exposed.
上記のごとく、高圧部内の固液分離装置は、全体が高圧

号１ｊ″；（高濃度スラリーを供給することができる。As mentioned above, the solid-liquid separator in the high-pressure section is entirely within the high-pressure section, so it is pressure-balanced, so even if it becomes larger, there will be no structural problems, and the slurry pump is also used for low-concentration slurry. Since large-capacity products have been manufactured in the past, the capacity of the entire device can be designed within a wide range. Slurry can be supplied.
