Detailed description of the invention
For making those skilled in the art better understand technical scheme of the present invention, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Concentration device for material liquid in the present invention, is jointly promoted the evaporation of solvent in low concentration feed liquid, realizes the concentrated purification of feed liquid by heating and the acting in conjunction of negative-pressure vacuum.
Fig. 1 is concentration device for material liquid schematic diagram of the present invention, as can be seen from Figure its cooling package having feed liquid evaporimeter and be connected with feed liquid evaporator series.Wherein feed liquid evaporimeter realizes the concentrated purification of feed liquid, and cooling package realizes the recycling (cooling package is not realize feed liquid concentrating function) of follow-up heat.
Specifically, feed liquid evaporimeter comprises heater 1, vaporization chamber 2 and makes vaporization chamber 2 produce the vavuum pump of subnormal ambient.Heater 1, for heating the feed liquid be poured in wherein, improves the temperature of feed liquid, the life film and the solution passing through to heat around the bubbles entrain making solvent volatilization generation expands.Vaporization chamber 2 is sealed shell of tank structures, and volume is comparatively large, and under vavuum pump suction function, vaporization chamber 2 forms the subnormal ambient lower than atmospheric pressure pressure; According to the gentle relation being pressed into inverse ratio of the volatilization of liquid, subnormal ambient is beneficial to the evaporation of feed liquid.
There are two connecting pipelines between heater 1 and vaporization chamber 2, be respectively be arranged in upside, for by feed liquid from heater 1 be transported to vaporization chamber 2 the first pipeline 3 and be positioned at downside, make vaporization chamber 2 feed liquid be back to the second pipeline 4 of heater 1.Feed liquid is at heater 1, first pipeline 3, between vaporization chamber 2 and the second pipeline 4, circulation solvent flashing, solute concentration increase gradually.
Traditional feed liquid evaporimeter, the pipeline connecting heater 1 and vaporization chamber 2 is shorter straight line pipeline, and the foam material liquid that raw film produces enters into vaporization chamber 2 fast through shorter straight line pipeline and also hurtles down under gravity, is deposited on bottom vaporization chamber 2.Like this, feed liquid not enough surface areas is evaporated in subnormal ambient, needs longer circulation timei and more heat exhaustion just can reach certain concentration value.
For improving the evaporation efficiency of feed liquid, the method by the specific area increasing feed liquid evaporation improves evaporation efficiency.For this reason, the present invention is by the end of the first pipeline 3, and namely the part of the first pipeline 3 conducting vaporization chamber 2 is set to spiral section 31.Adopt this structure, the gas-liquid mixed feed liquid that raw film produces from heater 1 creates rotation at spiral section 31, the inside of vaporization chamber 2 is cut at the end of spiral section 31, the eddy current rotated is formed along vaporization chamber 2 surface, instead of the directly mode of falling as traditional structure falls, improve the specific area of feed liquid evaporation, namely improve the disengagement area of unit volume feed liquid, increase the evaporation rate of feed liquid.
Fig. 2 is A-A face schematic diagram in Fig. 1, and it has intercepted the horizontal cross-section of the coupling part of vaporization chamber 2 and the first pipeline 3, can see that the spiral section 31 of the first pipeline 3 in publishing picture is end and the tangent semicircle of vaporization chamber 2 sidewall.Can expect, the plane tangent of end coils bearing of trend and vaporization chamber 2 be not represent both completely tangent, under ideal conditions, the extension of spiral section 31 can be tangential on the sidewall of vaporization chamber 2, and the spiral section 31 of other positions can not be tangential on vaporization chamber 2.It should be noted that in Fig. 2, spiral section 31 is a kind of special circumstances for semicircle, also can be the spiral section 31 of other angles or characteristic.
Also can find out from Fig. 2, vaporization chamber 2 can be circular vaporization chamber 2 for cross section, and namely whole vaporization chamber 2 main body (getting rid of two ends connection, hermetic unit) can be column structure; Certainly, its cross section also can be the polygonized structure of other evaginations, does not hinder the formation of swirling helical; But can expect, under identical sectional area and volume prerequisite, other polygonized structures want less relative to the evaporation efficiency of the vaporization chamber 2 of column structure.
Separately it is noted that heater 1 of the present invention can adopt the Steam Heating or high-pressure water heating heating used in conventional art, the modes such as the electrical heating that other field also can be adopted to use, as long as realize improving feed temperature and raw film.But consider that adopting high-temperature steam or high-pressure water heating mode of heating comparatively stably can maintain temperature fluctuation in heating-up temperature, minimizing heating process, on the impact of feed liquid, is preferably Steam Heating or high-pressure water heating mode of heating.In addition, consider from the structure of heater 1, it can be tube heater 1, also can be baffle heater 1, but should ensure can give birth to film preferably in heater 1, prevents from making bubble quick crashing because heater 1 space is less, reducing raw membrane efficiency.
From amechanical angle analysis, for forming eddy current, the feed liquid entering into vaporization chamber 2 from the first pipeline 3 spiral section 31 should have certain speed, and speed is the bigger the better; And only may feed liquid speed can not be made enough large through spiral section 31.
For increase feed liquid circulate speed, the present invention is provided with the assisted circulation device 5 promoting feed solution flow in the second pipeline 4, by the effect of assisted circulation device 5, while increasing the raw membrane efficiency of feed liquid and cycle rate, also improve and enter vaporization chamber 2 feed liquid speed, the spiral quantity formed is increased, improves evaporite ratio surface area.Separately can expect, impetus due to assisted circulation device 5 adds the flowing of feed liquid, also can prevent from the heat exchange wall of heater 1, attaching the larger feed liquid solute of viscosity and reducing heat exchange efficiency and prevent solute from affecting concentrate color, quality at heater 1 heat exchange wall side high temperature cabonization.Assisted circulation device 5 can be comparatively common centrifugal pump, axial-flow pump or mixed-flow pump.Certainly, also assisted circulation device 5 can not be set, only adopt heater 1 to add the flow circuit of thermogenetic raw membrane interaction promotion feed liquid.
Also can expect, under being in negative pressure state, first pipeline 3 can realize solvent evaporation from the gas-liquid mixed feed liquid of heater 1 outflow due to the first pipeline 3 and vaporization chamber 2 conducting.For being increased in the evaporation rate in the first pipeline 3, the first pipeline 3 can be set to rectangle pipeline, increase the area in gas-liquid separation face; Certainly, cross section such as traditional circular pipe of other types also can realize the evaporation of aforementioned feed liquid in the first pipeline, but evaporation effect may be not so good as rectangle pipeline.
Concentration device for material liquid in the present invention can arrange multistage above said feed liquid evaporimeter.Multistage feed liquid evaporator series connects, and realizes concentrating step by step of feed liquid, makes full use of heat; Certainly, also one-level feed liquid evaporimeter can only be adopted according to the actual requirements.Concentration device for material liquid in FIG have employed two-stage feed liquid evaporimeter exactly.Concentration device for material liquid in Fig. 1 have employed water as feed liquid medium, the feed liquid evaporimeter being wherein positioned at front side is the first evaporimeter, the feed liquid evaporimeter being positioned at rear side is the second evaporimeter, the heating intake line conducting of the vaporization chamber 2 of the first feed liquid evaporimeter and the heater 1 of the second feed liquid evaporimeter, the steam namely got rid of from the first feed liquid evaporimeter is as the thermal source of the second feed liquid evaporimeter, and the heater 1 through the second feed liquid evaporimeter is passed to the feed liquid being arranged in the second feed liquid evaporimeter.Certainly, when first order vaporization chamber heat can not reach job requirement, extraneous steam also can be introduced to rear stage heater.
The feed liquid of the second feed liquid evaporimeter is obtained by the first feed liquid evaporator evaporation partial solvent.For the feed liquid of the first feed liquid evaporimeter is transferred to the second feed liquid evaporimeter, the two arranges connecting pipeline at bottom section, connecting pipeline is provided with the valve controlling whether conducting.In addition, also there is in the first feed liquid evaporimeter front end compensator and delivery pump and corresponding valve, for storing the low concentration feed liquid that preorder production process is produced, and according to the level condition of the first feed liquid evaporimeter and concentrated situation to the new feed liquid of the first feed liquid evaporimeter pumping.Above valve all can adopt magnetic valve, by the opening and closing of each magnetic valve of Collaborative Control, realizes the conveying of variable concentrations feed liquid.From Fig. 1, pipeline also can be found out, the assisted circulation device 5 in each feed liquid evaporimeter also can be used as the power source to rear stage evaporimeter conveying feed liquid.
Fig. 1 not show but the core of concentration device for material liquid of the present invention, is also shown by its supporting thermal source supply line.Corresponding steam supply pipe road provides saturated vapor directly to the heater 1 in the first feed liquid evaporimeter, return line backflow residual steam and condensate water; The high-temperature steam got rid of by vaporization chamber 2 top in the first feed liquid evaporimeter heats to the feed liquid in the second feed liquid evaporimeter for heater 1 import transferring to the second feed liquid evaporimeter by the road, and is back to the return line of thermal source supply line through return line.In addition, in steam supply pipe road and return line, be provided with steam drainage valve gear, automatically discharge the steam condensate in firing equipment and pipeline and on-condensible gas.
Said concentration device for material liquid have employed water as feed liquid solvent above, therefore can directly by the steam conducting of previous stage vaporization chamber 2 to rear stage heater 1.As adopted other media if ethanol, ketone are as solvent, for realizing recycling, the decreasing pollution of this kind solvent, then can not method of attachment arrange described above, but completely independently thermal source supply line and feed liquid pipeline are set, the intersection that can not realize the two is communicated with, the steam that also just previous stage can not be produced is as the thermal source of rear stage heater, and the valve in corresponding previous stage vaporization chamber 2 and rear stage heater connecting pipeline needs to close.
Meanwhile, it shall yet further be noted that because part feed liquid can be expanded to foam in previous stage vaporization chamber 2, containing a large amount of feed liquid solute in foam, directly can be caused a large amount of wastes of active principle by pipeline conducting to the heater 1 of rear stage feed liquid evaporimeter.For this reason, as Fig. 1, also be provided with foam separator 6 in the upside of previous stage vaporization chamber 2, utilize foam separator 6 bubble collapse carrying effective substance is become feed liquid liquid and makes feed liquid liquid backflow to vaporization chamber 2, and only make steam by the heater 1 of Pipe transfer to rear stage.As a kind of possibility situation, as technological parameter or feed liquid characteristic can not form a large amount of foam in vaporization chamber 2, also foam separator 6 can not be set.
Analyze the core of concentration device for material liquid above, the concentration device for material liquid in accompanying drawing 1 have employed multistage feed liquid evaporimeter, it should be noted that according to application demand, also only can arrange one-level feed liquid evaporimeter.
For some field, although feed concentration is very high, but still its instructions for use (as Chinese medicinal granule common in Chinese herbal medicine industry or Crataegi pill etc.) can not be met, need to concentrate further.And due to dense, adopt aforesaid feed liquid evaporimeter can not give birth to film, feed solution flow also very poor.For this reason, concentration device for material liquid of the present invention is also provided with for this applicable cases and stirs evaporimeter 8.
Stir evaporimeter 8 there is agitator 81, volatilized in room 82 in the stirring of conducting of circulating with agitator 81 and for making stirring room 82 of volatilizing produce the vavuum pump of subnormal ambient.The vavuum pump that vavuum pump can adopt feed liquid evaporimeter above to use, also can be the vavuum pump arranged separately.
