The climbing film and falling film type multi-effect water distillator comprises a condenser (1), preheaters (2), and evaporators (3), which are connected successively. The evaporators (3) comprise first-effect evaporators and second-effect evaporators. The climbing film and falling film type multi-effect water distillator is characterized in that raw material water inlets (4) of the first-effect evaporators or the first-effect evaporators and second-effect evaporators are disposed at the lower ends. By employing a technical structure of climbing film and falling film evaporation, the climbing film and falling film type multi-effect water distillator enables raw material water to enter a tube pass from the bottoms of the first-effect evaporators or the first-effect evaporators and second-effect evaporators and realizes uniform distribution of the water naturally.

Description
Technical field
The utility model relates to a kind of film and falling film type multi-effect water distillator of rising, and belongs to the pharmaceutical equipment field.
Background technology
At present, most of pharmacy producer all need use multi-effect water distillator, and the technology of multi-effect water distillator is also ripe relatively.Owing to the difference of technology, the multi-effect water distillator of multiple structure formation is arranged on the domestic and international market, the product that these are dissimilar, its technology all has something in common.All form by a plurality of vaporizers, a plurality of preheater, condensing surface and pipeline.Water preparation process is: total raw material water delivers into condensing surface through pipeline; By condensing surface output and the like get into and respectively imitate preheater; Raw water finally gets into tube side by the 1st effective evaporator top and is distributed in each tubulation; Feed Boiler Steam in the shell side and calorify the raw water formation falling film type evaporation mode in the tube side; 1st effective evaporator evaporates remaining raw water and falls to base of evaporator, under the secondary steam force that the 1st effective evaporator evaporation produces, gets in the tube side of 2nd effect evaporator top, and the secondary steam of 1st effective evaporator generation simultaneously gets into the 2nd effect evaporator shell side and continues the raw water in the heating evaporation tube side; Follow-up each single-effect evaporator principle of work is identical, and the rest may be inferred to the remaining condensed water discharge of last effect evaporation.There is following drawback in the multi-effect water distillator of these conventional process techniques:
1, the zero(ppm) water of multi-effect water distillator preparation: be that steam in the utilization shell side is with the raw water heating evaporation in the tube side; Evaporation forms in the tube side secondary steam and unevaporated raw water; The lower end that together goes downwards to vaporizer forms steam water interface; The built-in water separator in flash-pot lower end makes carbonated drink obtain separating, and separated moisture is carrying the bacterium corpse and falling to base of evaporator and collect in the raw water, got in the tube side at lower effective evaporator top by the promotion raw water of secondary steam pressure; Continue to produce the evaporation sepn process, each imitates evaporating principle, and identical the rest may be inferred imitates condensed water to the end and discharge.Such technology drawback is: the first isolating thalline of evaporation of imitating is along with raw water has got into lower effective evaporator again; Originally it is high more to be that raw water evaporates cell concentration more; Cause for like this each single-effect evaporator of back to be unfavorable for carbonated drink and the isolating hidden danger of thalline (carbonated drink isolating more thorough and zero(ppm) water quality that obtain is high more), finally the water for injection of output (bacteria endotoxin content index height) of poor quality.
2, the multi-effect water distillator of conventional process techniques; All raw waters all are to be got in the tube side by the 1st effective evaporator top; So just cause the water flux density in the tube side big; 1st effective evaporator can not all evaporate all raw waters, only can evaporate about 1/3rd the water yield of the total raw material water yield, and most unevaporated raw waters are consuming the steam thermal energy in the shell side in vain in the tube side.Must cause steam consumption quantity big, evaporate insufficiently, the secondary steam of a large amount of unevaporated raw waters and generation forms the carbonated drink admixture.Moisture content in the consequent secondary steam is big; Thereby cause the built-in water separator inferior separating effect of vaporizer, the secondary steam moisture content after the separation is high, and the heat energy value is low; Supply with each quality of steam thermal energy differential of imitating of back, must cause the high drawback of complete machine operation energy consumption.
3, the raw water taked of conventional process techniques is by vaporizer top mode of entrance.Because different its heat interchanging areas of specification of equipment are just different; The tubulation quantity of vaporizer and sectional area are also different relatively; The top water intake mode is to be difficult to realize all tubulation water distribution isostatic, and inevitably can produce discharge in the tubulation has and fewly more, even the part tubulation is in anhydrous state; Raw water receives the influence of the steam reactive force of lower end in the vaporizer cavity again in the descending process in tube side, be prone to cause the phenomenon of paroxysmal flowing water.Cause the raw water flow velocity too fast or flow velocity is unstable, the heat interchanging area of vaporizer can not be fully utilized, and energy utilization is not enough, and the complete machine volatility is poor, the low drawback of usefulness.
4, because all raw waters all are to be got into by the 1st effective evaporator top; Raw water top-down mode of flowing through in generating tube must form the gravity flow velocity; Add raw water again under the force of transferpump; The flow velocity of flowing through in the tube side is faster, has so just shortened water and the steam heat time swap in the shell side in the tube side greatly, thereby has caused the low drawback of heat exchanger efficiency.
The utility model content
Improving existing multi-effect water distillator equipment and technology exists not enough; The utility model technical problem to be solved is: a kind of film and falling film type multi-effect water distillator of rising is provided; Energy consumption is low and heat exchanger effectiveness is high; Its bacteria endotoxin content of the zero(ppm) water of output (water for injection) is lower, reduces the manufacturing cost of producing cost and equipment of zero(ppm) water simultaneously greatly.This product brings quality product to improve will for pharmaceutical manufacturing enterprise, the huge advantage that production cost reduces; Will produce the development of distillation machine product and drive and promoter action.
The technical scheme that the utility model adopted is: a kind of film and falling film type multi-effect water distillator of rising is provided; Comprise the condensing surface, preheater and the vaporizer that connect successively; Vaporizer comprises 1st effective evaporator and 2nd effect evaporator, it is characterized in that the raw material water-in of an effect or, 2nd effect evaporator is arranged on the lower end.
Described 1st effective evaporator is 1.
Described 1st effective evaporator is 2.Utilization one effect or one, 2nd effect evaporator bottom get into evaporation mode.
Present technique adopts rises film and falling film type multi-effect water distillator, not all raw water all from one imitate or one, the entering of 2nd effect evaporator bottom.But according to one imitate or one, the actual steam capability base feed water of 2nd effect evaporator.All the other raw waters backward by the top of single-effect evaporator get into and the like the distribution evaporation.Such technical pattern characteristics are: raw water is got into from an effect or, 2nd effect evaporator bottom also realize uniform distribution the tube side naturally; The slowly evaporation of rising of raw water from bottom to top horizontal plane in tube side; Because raw water supplies water according to the actual steam capability of vaporizer; So the raw water in the tube side just can almost reach the state of evaporation fully; The secondary steam that produces arrives the upper end of vaporizer cavity; Through built-in water separator, isolate higher-quality secondary steam and supply with each vaporizer continuation heating evaporation of back; Simultaneously, one imitate or one, bacterium thalline and the less moisture of 2nd effect evaporator evaporation after separating is dissolved in one and falls to base of evaporator and directly discharge.Why the present technique invention adopts an effect or, 2nd effect evaporator bottom water inlet raw water mode.Mainly be utilization one imitate or one, performance advantage that 2nd effect evaporator is good, to satisfy each energy working conditions of imitating of back.Particularly used high-quality secondary steam to supply with back single-effect evaporator heating and used, acting is transmitted in each usefulness displacement makes the complete machine steam capability be significantly improved; Next is that an effect or, two is imitated the direct discharging of effect conveying downwards of the remaining raw waters of evaporation (evaporating the few and mycetome of the remaining water yield).Separate burden thereby alleviated back each carbonated drink that imitates, improved the quality of output water for injection greatly.Therefore: adopt and rise film and falling film type technical pattern, get into the water distribution inequality that exists from the vaporizer top thereby thoroughly solved raw water of the prior art; Raw water top-down mode flow velocity of flowing through in tube side is too fast or be vulnerable to the influence of secondary steam pressure reactive force, produces the phenomenon of paroxysmal flowing water; The gas that evaporation forms is the carbonated drink admixture causes inferior separating effect, thereby causes the water for injection of output of poor quality (bacteria endotoxin content is high); Evaporation separates the technological drawback of the of poor quality and heat energy value low (moisture content is many) of secondary steam that the back produced.
The beneficial effect of the utility model is:
1, adopt and to rise the technical pattern of film and falling film evaporation, be with raw water imitate through one or one, the bottom of 2nd effect evaporator, the equally distributed evaporation mode of realization naturally also in the water inlet tube side.Thoroughly solve the water inlet of 1st effective evaporator used in the prior art top and produced the uneven drawback of water distribution.Because raw water is from bottom to top the horizontal plane evaporating principle that rises synchronously in tubulation, so the secondary steam that produces can rise to upper end of evaporator by nature.So just avoided the raw water of prior art to be got into by the vaporizer top, secondary steam that is produced and the raw water that does not evaporate together go downwards to the lower end of vaporizer, thereby secondary steam produces reactive force upwards, thereby cause paroxysmal flowing water phenomenon.
2, because the raw water of prior art all is the entering of 1st effective evaporator top; Raw water top-down mode of flowing through in generating tube must form the gravity flow velocity; It is faster to add the flow velocity that raw water flows through under the force of transferpump in the tube side again; Shorten water and the steam heat time swap in the shell side in the tube side greatly, thereby caused the low drawback of heat exchanger efficiency.Raw water in the present technique invention is by an effect or, 2nd effect evaporator bottom mode of entrance; Ratio with the raw water top water intake mode of prior art; Feed water stream is opposite to fully, has overcome not only that the raw water flow velocity is too fast influence water flow velocity drawback sooner with the force that is subject to transferpump, and flow velocity is slow on the contrary; More make raw water and the steam in the shell side in the tube side that enough heat-exchange times are provided, heat exchange efficiency is higher more abundant.
3, because the multi-effect water distillator of prior art; All raw waters all are through 1st effective evaporator; 1st effective evaporator can not all evaporate all raw waters; Only can evaporate about 1/3rd the water yield of the total raw material water yield, most unevaporated raw waters are consuming the steam thermal energy in the shell side in vain in the tube side.Must cause steam consumption quantity big, evaporate insufficiently, the secondary steam of a large amount of unevaporated raw waters and generation forms the carbonated drink admixture.Moisture content in the consequent secondary steam is big; Thereby cause the built-in water separator inferior separating effect of vaporizer, the secondary steam moisture content after the separation is high, and the heat energy value is low; Supply with each quality of steam thermal energy differential of imitating of back, must cause the high drawback of complete machine operation energy consumption.And the present invention gets into the bottom of raw water through an effect or, 2nd effect evaporator, and again according to the actual steam capability base feed of 1st effective evaporator water, all the other raw waters single-effect evaporator backward distribute evaporation.Such know-why has promptly reduced the steam consumption of 1st effective evaporator; Raw water is all evaporated; Evaporating the secondary steam that on the contrary is at upper end of evaporator, so just can not produce steam water interface and inferior separating effect situation, has improved the saturation ratio of the secondary steam that produces; Improved the heat energy value of steam again, supplying with for each single-effect evaporator of back provides higher-quality heat energy.
4, employing rises the multi-effect water distillator technical pattern that film combines with falling liquid film, with the various multi-effect water distillators contrasts of market prior art.Technology of the present invention mainly is to have used an effect or, the rational water distribution manner of 2nd effect evaporator; And perfect evaporating principle and performance; Can supply with back single-effect evaporator heating use by the high-quality secondary steam of output, make complete machine working efficiency and performance obtain huge raising.Because an effect or, 2nd effect evaporator is rational in infrastructure, evaporation effect is good, and heat exchange efficiency is high.Thoroughly solved multi-effect water distillator of the prior art, exist under equal conditions and heat interchanging area big, equipment volume is big, device fabrication uses consumption material big, equipment occupation space is big, drawbacks such as the high and poor performance of complete machine working cost.
In sum: owing to rise reasonableness and the maturity thereof that film and falling liquid film structure technology possess, compare with existing various distillation machines, present technique has that equipment volume is little, little, the low cost of manufacture of taking up room, working cost are low.Evaporation effect is good, and heat exchange efficiency is high, and it is low that the zero(ppm) water of institute's output (that is: water for injection) is produced cost, and each item index of water for injection quality is significantly improved, and (as: requirement and the existing standard of specific conductivity have fallen 8～15%; Total organic carbon has reduced by 15～25%; Bacterial endotoxin has reduced by 20～30%).Bring quality product to improve must for like this pharmaceutical manufacturing enterprise, production cost reduces, and evades the huge advantage of quality product risk.
