Description
Technical field
The utility model relates to the agricultural wastes straw treatment technology, and specifically, the utility model relates to a kind of orientation and disassembles stalk fibre equipment.
Background technology
Stalk is processed the attention that more and more obtains government and peasant in China, particularly to the supervision of PM2.5 particle in air, crop straw burning has obtained basic controlling now, but we are now only using the wheat head of complete stool wheat 20% as grain, all the other stalks of 80% are lost in the ground as discarded object by the peasant, a large amount of stalks causes the peasant that most of stalk one is directly burnt fire because depositing nowhere, has caused like this wasting of resources and environmental pollution.
In recent years, the pretreated method of research stalk is also a lot, and they are respectively chemical method, thermal spraying, cooking process, the quick-fried method of vapour.Wherein chemical method is due to environmental protection and disposal cost is high is eliminated; Thermal spraying need need long-time cooling to processed stalk high cooking pressurize and ejection material, in the equipment discharging, containing too much half-cooked material, it is not thorough that stalk is disassembled 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, will directly cause the stalk product cost high, affects its industrialized application; The quick-fried method of vapour is that Recent study is maximum, also that the Treating straw time is the fastest, do not have the most promising stalk of ambient influnence to disassemble into the physical method of fiber, on the key technologies such as current this technology focus mainly concentrates on and heats, pressurization and decompression time, there is the scholar to propose the fast opening type stalk technology of releasing, the methods such as proposition " continuous steam explosion machine " are also arranged, but these methods are all after the system decompress(ion) abroad, biomass straw, was just released by complete decompress(ion) from tens seconds within time a few minutes; Also there is the scholar that the quick-fried system of vapour decompression time is controlled to 0.005075s≤S≤0.00875s time period, its effect is the physics requirement that has realized that vapour is quick-fried in the physical sense, and do not reach the so fast time, for stalk, " spurt " and " expanded " these two kinds of fiber treatment states, the fiber that above-mentioned two kinds of physical states obtain can not be done epidemic situation comparison with " vapour explosion ", these two technology and fiber are disassembled state and all are different from itself the quick-fried technology of vapour
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 take abroad most advanced " continuous steam explosion equipment " that Canadian Sang Puda company is representative.
The common feature of the quick-fried treatment facility of batch (-type) stalk vapour is to be structurally by boiler, the ball valve that steam-explosion jar and opening time are greater than the 0.00875s time forms, this type of quick-fried treatment facility of stalk vapour is except can not completing in the physical sense " vapour explosion ", also show due to the force value in steam-explosion jar by large to zero variation, the stalk that makes the stalk of ejection at first and finally spray is because residing pressure is different, many half-cooked material have been shown, the fiber yield is low, trace it to its cause is that relative ball valve slowly of an opening time is opened the first second of valve core at it, pressure in steam-explosion jar is just reducing, along with the time, to pass relatively slowly pressure drop faster, this is just away from " vapour explosion " condition on the physical significance, only have the 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 still mainly is used in so far laboratory and produces a small amount of gas-explosive material, be used for aspects such as the quick-fried technical study of vapour and assessments, now the peasant also just illustrates such reason at a large amount of crop straw burnings 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 the heating of 4MPa high-pressure boiler, by the high-pressure boiler pressurization that heats up, but high-pressure boiler is no matter on manufacturing cost, or all to expend mass energy on increasing temperature and pressure, except directly causing product and cost of equipment maintenance rising, greatest problem is still brought new problem of environmental pollution, again because boiler in heating process, its vapor (steam) temperature and pressure are to be the function corresponding relation, temperature is higher, pressure is larger, because this boiler method can not independently be controlled on temperature and two indexs of pressure, so just the problem of fiber quality has occurred to affect in practice, stalk is under high temperature action, stock-dye group is from the golden yellow of stalk script, to be cracked into brown-black, physicochemical change occurs, continue the carbonization of intensification stalk, and this type of equipment can only heat up by continuation, 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 the fiber needs, can not control the stalk be disassembled lysate Physicochemical reaction speed does not occur, and due to high temperature action straw charring the most at last, outward appearance is the powdery atrament, can't obtain the stalk fibre of golden yellow outward appearance, also just can't obtain high-valued stalk fibre.So it is still generally approved that the quick-fried treatment facility of batch (-type) stalk vapour is confined to principle prototype.
Take that Canadian Sang Puda company is representative now abroad most advanced " continuous steam explosion equipment " also exist same problem, the one, in the equipment pressurizing chamber, the steam pressure 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, on stalk, effectively do not discharged, it is many that the equipment decompress(ion) spurts in rear fiber half-cooked material, also exist ball valve in frequently spurting process, the vapour losses amount is large, boiler heating boosts slowly, in the equipment pressurizing chamber, moisture content of straws can not be controlled, though the decompress(ion) ball valve has adopted carbide alloy, but serious wear, quality preferably its life-span of ball valve also with regard to one month.

One-level heating unit, secondary heating unit and three grades of heating units are one group of assemblys that meet electric Δ or Y connection, the one group of assembly that meets electric Δ or Y connection of electrical connection between three dry combustion method heating tubes 52.
Heated shell 51 is rectangular tubular, adopts 304# stainless steel rectangular pipe to make.Heated shell 51 is installed on the outer cylinder body 10 of disassembling tank 1 by the fixed block of outer setting, and is vertically to arrange.
Heated shell 51 closed at both ends, inner hollow, its inside is medium channel.In heated shell 51, also be welded with along its length the baffle plate 54 of even number rectangle, baffle plate 54 is staggered to be arranged symmetrically with, and the medium channel of formation is the snakelike heat tunnel that allows medium pass through.Baffle plate 54 starts along with the perpendicular direction of heated shell 51 length directions, extend to the centre position of heated shell 51 always from the madial wall of heated shell 51, and the area of baffle plate 54 is half of heated shell 51 internal cross-sectional area.Blind pipe 53 passes each baffle plate 54 at the middle part of heated shell 51, on each baffle plate 54, has semicircular hole.
The number of heated shell 51 interior panellings 54 is by the overall length decision of the medium channel of design, and the longer heat exchanger effectiveness of medium channel is just higher, and the temperature rise speed of water vapor speed and steam is just faster.In this superheated steam generator 5, four baffle plates 54 are set in the heated shell 51 of each heating unit, be divided into the even number decile, one group is located at respectively on two relative madial walls of heated shell 51 in twos.
In heated shell 51, be furnished with along its length a blind pipe 53, blind pipe 53 passes all baffle plates 54 by the semi-circular hole on baffle plate 54.Blind pipe 53 adopts the 304# stainless steel tube to make, the diameter of blind pipe 53 is than the large 1mm of the diameter of dry combustion method heating tube 52, dry combustion method heating tube 52 inserts in blind pipe 53, blind pipe 53 two ends are connected with the two ends inner wall sealing of heated shell 51, just formed the cavity that is closed state between blind pipe 53 and dry combustion method heating tube 52, do not allow high-temperature steam or seepage, guarantee that water power vapour separates fully.
