Abstract

A technology for preparing the paper pulp from the fibres of oilpalm shell includes loosening, sieving to remove sandy dust, washing in water to remove impurities, filter drying, loosening, high-temp digestion, spray puffing, squeezing drying, tearing off, heating, high-concentration rinsing, grinding pulp and removing dregs.

Description

With oil palm shell string fiber method for making paper pulp
Technical field
The present invention relates to a kind of method for making paper pulp, particularly a kind of with oil palm shell string fiber method for making paper pulp.
Background technology
Extensively utilize the high-quality paper pulp papermaking of timber system in paper-making industry at present, because the wastage of current paper is huge, thereby make the cutting capacity of global forest increase severely, the area of whole world forest falls sharply significantly, cause ecological problem, abound with oil palm in south east asia, and the oil palm shell that rolls behind the oil goes out of use, burn, cause environmental pollution, become focus, but contain sand because it has in the pericarp inwall blackspot flesh skin that is different from timber and the oil palm case fibre with the oil palm shell papermaking of fibre rich slurry, and the oil palm case fibre is thick caking shape, and therefore existing paper process can't be made paper pulp with the oil palm case fibre.
Summary of the invention
The objective of the invention is to solve the oil palm shell papermaking slurry of using fibre rich in the prior art, but, it contains sand because having in the pericarp inwall blackspot flesh skin that is different from timber and the oil palm case fibre, and the oil palm case fibre is thick caking shape, and therefore existing paper process can't be made the oil palm case fibre problem of paper pulp.The present invention designs with oil palm shell string fiber method for making paper pulp, it is characterized in that being made up of the following step:
(1) oil palm shell string fiber is discongested the fiber of caking by dry method, and removes sand dust by screen cloth,
(2) with the weight impurity in the washing of the fiber utilization after the step (1) defibre, the heavy seeds precipitation is discharged, and light impurity is discharged by water surface rinsing,
(3) aqueous fibre after the step (2) is done by the spiral drying machine filter,
(4) fiber after filter is done is sent into and is not had the soda acid thermophilic digestion in the boiling vessel through discongesting steamer, and temperature is controlled at 170 ℃-180 ℃, makes fiber softening, spurt again expanded,
(5) fiber that is pulpous state is extracted slabbing by six roller twin-wire press,
(6) fibre sheet is torn up by shredder,
(7) spiral heater heating is sent into the rinsing of high concentration rinsing tower through the dense mixer of height,
(8) screening back defibrination slagging-off.Be used to realize that the dry method of claim 1 discongests the dry method fluffer of caking fiber, comprise casing, motor, its feature exists: runner is arranged in the casing, be evenly distributed with the hammer leaf seat on the runner outer rim, there is rotating shaft to link to each other on the hammer leaf seat with hammer leaf, be distributed with the gear piece of protrusion on the casing inner wall, bottom of shell has screen cloth.
Be used for realizing the washing separator of the washing defibre weight impurity of claim 1, comprise casing, motor, its feature exists: stirring wheel is arranged in the casing, bottom of shell has the precipitation cone tank, under the precipitation cone tank outlet is arranged, flotation cell is arranged at casing top, and flotation cell inner side edge and casing join, the flotation cell outside is deep gouge, and following deep gouge has outlet.Advantage of the present invention can will go out of use, and the oil-palm serial shell fiber of burning is made paper pulp.
Description of drawings
Below in conjunction with drawings and Examples the present invention is elaborated,
Accompanying drawing 1 is a dry method fluffer structural representation of the present invention,
Accompanying drawing 2 is a washing cyclone separator arrangement schematic diagram of the present invention,
The specific embodiment
At first oil palm shell string fiber is put into the fiber of discongesting of dry method fluffer, casing 1 among Fig. 1, motor 2, its feature exists: runner 3 is arranged in the casing 1, be evenly distributed with hammer leaf seat 4 on runner 3 outer rims, there is rotating shaft 5 to link to each other on the hammer leaf seat 4 with hammer leaf 6, be distributed with the gear piece 7 of protrusion on casing 1 inwall, screen cloth 8 is arranged at casing 1 bottom, when the oil palm shell string fiber of caking is met after the hammer leaf 6 fly to change impacts, gear piece 7 on collision casing 1 inwall, the oil palm shell string fiber of caking is discongested is puffy, wherein the sand grains that comprises in the oil palm case fibre is sifted out by the screen cloth 8 of casing 1 bottom, with discongest be puffy fibre transportation to washing separator, comprise casing 10 among Fig. 2, motor 11, its feature exists: stirring wheel 12 is arranged in the casing 10, precipitation cone tank 13 is arranged at casing 10 bottoms, the precipitation cone tank has outlet 14 13 times, flotation cell 15 is arranged at casing 10 tops, flotation cell 15 inner side edges and casing 10 upper ends join, flotation cell 15 outsides are following deep gouge 16, following deep gouge 16 has outlet 17, when discongesting the fiber that is puffy when in the washing separator, stirring by stirring wheel 12, heavy impurity such as silt particle etc. can be deposited in the precipitation cone tank 13 of casing 10 bottoms, discharge the washing back, and light impurity such as inwall blackspot flesh skin can enter in the following deep gouge 16 in flotation cell 15 outsides from casing 10 upper ends, discharge by outlet 17 again, wet oil palm shell string fiber after cleaning is done by the spiral drying machine filter, oil palm shell string fiber after filter is done is sent into thermophilic digestion in the steamer, spurt expanded, the fiber that is pulpous state is extracted slabbing by six roller twin-wire press, and the sheet-like fiber sheet is torn up by shredder, is heated by spiral heater again, send the rinsing of high concentration rinsing tower, become high-quality paper pulp after the defibrination slagging-off of screening back.
