Description
Technical field
The present invention relates to agricultural wastes straw treatment technology, specifically, the present invention relates to a kind of orientation and disassemble stalk fibre equipment and disassembling method thereof.
Background technology
Stalk process more and more obtains the attention of government and peasant in China, particularly to the supervision of PM2.5 particle in air, crop straw burning obtains basic controlling now, but we now only using the wheat head of complete stool wheat 20% as grain, all the other stalks of 80% are lost in the ground by peasant as discarded object, a large amount of stalks causes peasant that most of stalk one is directly burnt fire because depositing nowhere, cause the wasting of resources and environmental pollution like this.
In recent years, the pretreated method of research stalk is also a lot, and they are chemical method, thermal spraying, cooking process, the quick-fried method of vapour respectively.Wherein chemical method due to environmental protection and disposal cost high and be eliminated; Thermal spraying need need long-time cooling to processed stalk high cooking pressurize and ejection material, containing too much half-cooked material in equipment discharging, it is not thorough that stalk disassembles into fiber, and institute's fiber yield that obtains is too low, the problems such as equipment investment is large, production occupied ground area is large, and be difficult to promote; Cooking process is due to needs longer time boiling stalk, and the time used is greater than thermal spraying and causes power consumption more, and by directly causing, stalk product cost is high, affects its industrialized application; The quick-fried method of vapour is that Recent study is maximum, also be that the Treating straw time is the fastest, the most promising stalk of ambient influnence is not had to disassemble into the physical method of fiber, current this technology focus mainly concentrates on heats, to pressurize and in the key technology such as decompression time, there is scholar to propose fast opening type stalk to release technology, also have the methods such as proposition " continuous steam explosion machine " abroad, but these methods are all after system decompress(ion), biomass straw, from tens seconds in time a few minutes, is just fully decompressed and has released; Also scholar is had by quick-fried for vapour system decompress(ion) time controling in 0.005075s≤S≤0.00875s time period, its effect is achieve the quick-fried desired physical considerations of vapour in the physical sense, and do not reach the so fast time, then " spurt " and " expanded " these two kinds of fiber treatment states for stalk, the fiber that above-mentioned two kinds of physical states obtain and " vapour explosion " can not do epidemic situation comparison, these two technology and fiber are disassembled state and are all different from steam explosion technology in itself
Most advanced abroad " continuous steam explosion equipment " that use the stalk device for disassembling of the quick-fried method of vapour to mainly contain the quick-fried treatment facility of batch (-type) stalk vapour and to be representative with Canadian Sang Puda company.
The common feature of the quick-fried treatment facility of batch (-type) stalk vapour is structurally by boiler, the ball valve that steam-explosion jar and opening time are greater than the 0.00875s time forms, the quick-fried treatment facility of this type stalk vapour is except can not completing " vapour explosion " in the physical sense, also show due to the force value in steam-explosion jar by large to zero change, make the stalk of the stalk that sprays at first and last ejection due to residing pressure different, many half-cooked material are shown, fiber yield is low, trace it to its cause is that an opening time relative ball valve slowly opens the first second of valve core at it, pressure in steam-explosion jar is just in reduction, along with the time, to pass pressure drop relatively slowly faster, this is just away from " vapour explosion " condition in physical significance, only have the more weak stalk of a small amount of lignin intensity can be disassembled into fiber, to such an extent as to the quick-fried treatment facility of stalk vapour is still mainly used in laboratory so far and produces a small amount of gas-explosive material, for to aspects such as the quick-fried technical study of vapour and assessments, now peasant also just illustrates such reason at a large amount of crop straw burning socially, boiler law technology bottleneck thus, it is the root of restriction industrial mass Treating straw.
In addition, the quick-fried treatment facility of batch (-type) stalk vapour all adopts 4MPa high-pressure boiler to heat, heated up by high-pressure boiler and pressurize, but high-pressure boiler is no matter in manufacturing cost, or in increasing temperature and pressure, all want the at substantial energy, except directly causing product and cost of equipment maintenance and rising, greatest problem still brings new problem of environmental pollution, again because boiler is in heating process, its vapor (steam) temperature and pressure are in function corresponding relation, temperature is higher, then pressure is larger, because this boiler method can not independently control in temperature and pressure two indexs, so just there occurs the problem affecting fiber quality in practice, stalk is under high temperature action, stock-dye group is from the golden yellow of stalk script, brown-black will be cracked into, there is physicochemical change, continue the then carbonization of intensification stalk, and this type equipment can only by continuing to heat up, equipment could continue to improve pressure, so this kind of equipment just can not adapt to variety classes biomass straw raw material, be processed into fiber needs, there is not lysate Physicochemical reaction speed in the stalk that can not control to be disassembled, and due to high temperature action straw charring the most at last, outward appearance is powdery atrament, the stalk fibre of gold appearance cannot be obtained, also just high-valued stalk fibre cannot be obtained.So the quick-fried treatment facility of batch (-type) stalk vapour to be confined to principle prototype still generally approved.
Also same problem is there is with current abroad most advanced " continuous steam explosion equipment " that Canadian Sang Puda company is representative, one is that in equipment pressurizing chamber, vapour pressure force value is difficult to stablize, more accurately do not control, equipment is not truly forming " vapour explosion " condition, the steam energy stored up is within the shortest time, effectively do not discharged on stalk, it is many that equipment decompress(ion) spurts half-cooked material in rear fiber, also there is ball valve is frequently spurting in process, vapour losses amount is large, boiler heating boosting is slow, in equipment pressurizing chamber, moisture content of straws can not control, though decompress(ion) ball valve have employed carbide alloy, but serious wear, its life-span of the good ball valve of quality is also with regard to one month.
