Abstract
The utility model relates to the field of carbon fiber preparation, in particular to a self-circulating LYOCELL fiber forming system which comprises a spinneret plate, a coagulating bath tank and a recovered bath foam storage tank. The spinneret plate is arranged above the coagulating bath tank, an air gap is formed between the spinneret plate and the coagulating bath tank, a bath foam drainage outlet of the coagulating bath tank is connected with a three-way valve through a pipeline, one outlet of the three-way valve is communicated with the recovered bath foam storage tank through a recovery pipeline, the other outlet of the three-way valve is communicated with a bath foam inlet of the coagulating bath tank through a circulating pipeline, and a heat exchanger and a metering pump are mounted on the circulating pipeline. Only bath foam needing to be conveyed back to the coagulating bath tank is cooled, cooling energy consumption is reduced, energy consumption of heating and concentrating can be reduced to a certain extent, energy is saved, environment is protected, production cost is lowered, and application and popularization of LYOCELL fibers are better facilitated.
Description
Technical field
The utility model relates to carbon fiber preparation field, relates in particular to a kind of LYOCELL fiberizing equipment.
Background technology
LYOCELL fiber is that international artificial fibre and the synthetic fiber standardization BISFA of office are the determined generic name of new fiber that organic solvent spin processes makes.LYOCELL fiber production process belongs to environmentally friendly machine, and discarded LYOCELL fiber can decompose completely in earth, greatly reduces the injury of environment and pollution.
LYOCELL fiber is used NMMO (N-methyl beautiful jade oxide) as cellulosic organic solvent when producing, the biochemical toxicity of NMMO is optimum, can not cause biomutation, the cellulose fibre process that the NMMO (N-methyl beautiful jade oxide) of take produces as solvent is physical process, without any chemical reaction, solvent recycles pollution-free, is called as environmental protection fiber.
In existing Lyocell spinning, mostly adopt the dry method that squirts, spinning solution (the NMMO solution of containing cellulose) by metering, filter, extruding spray silk becomes a stoste thread to enter coagulating tank to carry out coagulating bath, stoste thread is in coagulating bath, surface concentrated phase solvent and water are constantly diffused in coagulation bath, and stoste thread surface solidify to form as-spun fibre gradually.In order to guarantee the uniformity of fiberizing quality, strand coagulation bath around needs within the specific limits constant, and keep little fluctuation as far as possible, what the stoste of guarantee concentrated phase was stable like this separates out, the amount that stoste is brought into is very large, in order to keep the stability of temperature, in existing equipment, be all to realize by increasing the volume of bathing pool and circulatory pool, this way has improved investment construction cost and the floor space of equipment greatly, excessive bathing pool, the energy consuming in the time of also can improving body lotion recycle, make Lyocell fiber cost very high, be unfavorable for the popularization of Lyocell fiber.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of self-loopa LYOCELL fiberizing system, this system by heat exchanger by the cooling rear recycled back coagulating tank of quantitative coagulation bath, reduced the energy consumption of cooling needs, concentrated also uncooled body lotion can also reduce to heat concentrated energy resource consumption, in energy-conserving and environment-protective, reduced the production cost of LYOCELL fiber.
The utility model is achieved in that a kind of self-loopa LYOCELL fiberizing system, comprise spinnerets, coagulating tank and recovery body lotion storage tank, described spinnerets be arranged on coagulating tank directly over, between spinnerets and coagulating tank, leave air gap, the body lotion floss hole of described coagulating tank is connected with triple valve by pipeline, an outlet of described triple valve is communicated with recovery body lotion storage tank by reclaim line, another outlet of triple valve is communicated with the body lotion import of coagulating tank by circulation line, and heat exchanger and measuring pump are housed on described circulation line.
Filter is also housed on described circulation line.
Described heat exchanger is plate-fin heat exchanger.
Described air gap height is 5～100mm.
The aperture of described spinnerets is 0.05～0.1mm.
The utility model self-loopa LYOCELL fiberizing system by heat exchanger by the cooling rear recycled back coagulating tank of quantitative coagulation bath, cooling like this is carried out for the body lotion that need to send coagulating tank back to, energy consumption and the cool time of cooling needs have been reduced, without building again large-area recovery body lotion storage tank, reclaim simultaneously residue body lotion in body lotion storage tank directly heating concentrated after as the raw material of spinning solution, now body lotion is also completely not cooling, so can also reduce to a certain extent to heat concentrated energy resource consumption, the utility model not only can reduce construction cost, can also reduce production cost, in energy-conserving and environment-protective, more be conducive to applying of LYOCELL fiber.
Accompanying drawing explanation
Fig. 1 is the system block diagram of the utility model self-loopa LYOCELL fiberizing system.
In figure: 1 spinnerets, 2 coagulating tanks, 3 reclaim body lotion storage tank, 4 air gaps, 5 triple valves, 6 heat exchangers, 7 measuring pumps, 8 filters.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model statement, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1
As shown in Figure 1, a kind of self-loopa LYOCELL fiberizing system, comprises spinnerets 1, coagulating tank 2 and reclaims body lotion storage tank 3, the aperture of the spinnerets 1 in the present embodiment is 0.05～0.1mm, conventionally uses the spinnerets of 100 hole * 0.08mm; Described spinnerets 1 be arranged on coagulating tank 2 directly over, between spinnerets 1 and coagulating tank 2, leave air gap 4, the body lotion floss hole of described coagulating tank 2 is connected with triple valve 5 by pipeline, an outlet of described triple valve 5 is communicated with recovery body lotion storage tank 3 by reclaim line, another outlet of triple valve 5 is communicated with the body lotion import of coagulating tank 2 by circulation line, reclaim the body lotion in body lotion storage tank 3, directly the concentrated raw material as spinning solution of heating; Heat exchanger 6 and measuring pump 7 are housed on described circulation line, after quantitative body lotion being dispelled the heat by heat exchanger 6 by measuring pump 7, send back in coagulating tank 2 and use as body lotion, in order to keep smoothly the concentration of body lotion in coagulating tank 2, need appropriate to supplementing water in coagulating tank 2, the supplementary water yield can proportionally be supplemented according to the body lotion internal circulating load of measuring pump 7, also can rule of thumb be added by staff.
In the present embodiment, described heat exchanger 6 is plate-fin heat exchanger, can select freely as required air-cooled, water-cooled, then at corresponding external fan or cooling water circulation pipeline; A little less than considering that plate-fin heat exchanger anti-blockage capability is, liquid quality is had relatively high expectations, a filter 8 of extra series connection on circulation line, described filter 8 is arranged on the upstream of heat exchanger 6.
In the utility model, the height of air gap 3 is too low may be inadequate because of surface film in addition, and fibrillation may appear in excessive height, so as preferably this being highly set to 5～100mm.
