Below in conjunction with accompanying drawing the specific embodiment of the present invention is elaborated.Should be understood that embodiment described herein only is used for description and interpretation the present invention, is not limited to the present invention.
Horizontal evaporative concentration system of the present invention comprises evaporation concentration device 10 and gas-liquid separator 20, described evaporation concentration device 10 comprises water-supply pipe 11, medicine supplying pipe 12, horizontal rotary cylindrical shell 13, cooling storehouse 14, separation bin 15, spiral conveying parts 16, make the drive element 17 of described horizontal rotary cylindrical shell 13 rotations and the heater block 18 that described horizontal rotary cylindrical shell 13 is heated, described water-supply pipe 11 and described medicine supplying pipe 12 provide former water and medicament to described horizontal rotary cylindrical shell 13 respectively, described cooling storehouse 14 is connected between described horizontal rotary cylindrical shell 13 and the described separation bin 15, described spiral conveying parts 16 extend in the described separation bin 15 in described horizontal rotary cylindrical shell 13, and described separation bin 15 is communicated with described gas-liquid separator 20.
Wherein, drive element 17 can adopt various suitable structures, as long as can drive 13 rotations of horizontal rotary cylindrical shell.For example, as shown in Figure 1, drive element 17 can comprise motor 17a and belt 17b, and belt 17b passes to horizontal rotary cylindrical shell 13 with the rotation of the rotating shaft of motor 17a, thereby drives 13 rotations of horizontal rotary cylindrical shell.Those skilled in the art also can select the drive element 17 of other form to realize the rotation of horizontal rotary cylindrical shell 13.
In addition, heater block 18 can adopt various suitable forms, as long as can the major parts horizontal rotary cylindrical shell 13 that evaporation concentration is processed be heated.Because horizontal rotary cylindrical shell 13 is cylinder-like parts, for it is carried out homogeneous heating, preferably, described heater block 18 can comprise housing 18a, this housing 18a is set in the outside of described horizontal rotary cylindrical shell 13 and is tightly connected with described horizontal rotary cylindrical shell 13, thereby forms heated chamber 18b between described housing 18a and described horizontal rotary cylindrical shell 13.Heater block 18 can comprise various suitable heating units, such as resistance wire etc., perhaps puts into fuel and this fuel is burnt at heated chamber 18b in heated chamber 18b, so that heat energy to be provided.No matter adopt which kind of type of heating, the heat of generation all will be in heated chamber 18 uniformly dispersing, thereby evenly be delivered to horizontal rotary cylindrical shell 13 inside by the barrel of horizontal rotary cylindrical shell 13, process to be used for evaporation concentration.More preferably, can make heating unit or fuel along circumferentially being evenly arranged of horizontal rotary cylindrical shell 13, so that horizontal rotary cylindrical shell 13 is heated more equably.
Here, horizontal rotary cylindrical shell 13 and housing 18a can adopt high temperature material to make, for example horizontal rotary cylindrical shell 13 is made by stainless material or is formed by the high temperature ceramic material sintering, housing 18a is made by stainless material or is formed by the high temperature ceramic material sintering, high temperature (for example 600-1000 ℃) requirement when satisfying evaporation concentration.In addition, on the housing 18a thermoscope can be installed, with the temperature in the monitoring horizontal rotary cylindrical shell 13, thus the Heating temperature of regulating heater block 18 according to practical situation.
As mentioned above, former water evaporates because of the heating of heater block 18 in horizontal rotary cylindrical shell 13, so that the concentration of liquid increases and concentrates (horizontal rotary cylindrical shell 13 namely is the evaporation concentration treatment zone) and accelerate crystallization under the cooling effect in medicament and cooling storehouse 14, to form crystallized product, this crystallized product is solid substantially, may contain a small amount of liquid, but liquid can exist with the form of crystal water also on a small quantity, thereby make crystallized product be rendered as the solid of dryness.The steam of evaporation is discharged into the gas-liquid separator 20 from separation bin 15 and forms water of condensation, recycles thereby be used for industrial production.Wherein, separation bin 15 can be communicated with gas-liquid separator 20 by pipeline 21, and the valve of controllable switch can be set in pipeline 21 as required, with the connected sum partition of control separation bin 15 and gas-liquid separator 20.
By using horizontal rotary cylindrical shell 13, on the one hand, the liquid in the horizontal rotary cylindrical shell 13 rotates with the rotation of horizontal rotary cylindrical shell 13 when flowing, thereby makes more liquid exposure on water surface of evaporation, has therefore increased former evaporation of water area; On the other hand, the horizontal rotary cylindrical shell 13 that accumbency arranges, so that the crystallized product that former water evaporation concentration obtains is in the effect deposit of the self gravitation bottom to horizontal rotary cylindrical shell 13, thereby the crystallized product of deposition can be transported to separation bin 15 from horizontal rotary cylindrical shell 13 by the helical feed effect of spiral conveying parts 16.
In addition, when carrying crystallized product by rotating screw conveying parts 16, the blade of spiral conveying parts 16 can produce stirring action to the liquid in the horizontal rotary cylindrical shell 13, and so that a part of liquid turns to liquid level top with spiral conveying parts 16 and falls down, thereby further increased the evaporation area of liquid.
This shows, in Horizontal evaporative concentration system of the present invention, can carry out continuously evaporation concentration and gas-solid lock out operation.The incomplete liquid of evaporation concentration can continue to carry out evaporation concentration in horizontal rotary cylindrical shell 13 processes, thereby does not have the problem that the underflow crystalline mother solution is returned, and has also just eliminated block system, has returned and steam the possibility of polluting.
In addition, for the ease of connecting, described cooling storehouse 14 and described separation bin 15 also can be round shape, and can make the dead in line of described horizontal rotary cylindrical shell 13, described cooling storehouse 14 and described separation bin 15, thereby make described horizontal rotary cylindrical shell 13, described cooling storehouse 14 and described separation bin 15 coaxialalignments.In this case, cooling storehouse 14 can be set to and can rotate with horizontal rotary cylindrical shell 13.
Because horizontal rotary cylindrical shell 13 favours ground and arranges, thereby flowing fluid has the trend of backflow in horizontal rotary cylindrical shell 13, thereby is convenient to abundant evaporation.As shown in Figure 1, in order to prevent former water backflow leakage, the first end of described horizontal rotary cylindrical shell 13 has sealing plate 13a, has water-supply pipe interface and medicine supplying pipe interface on the sealing plate 13a; In addition, the second end of described horizontal rotary cylindrical shell 13 can be tightly connected with described cooling storehouse 14 (for example by sealing-ring horizontal sealing rotary barrel 13 and the end face that docks that cools off storehouse 14), to guarantee that evaporating concentration process carries out under air-proof condition.Certainly, in order further to guarantee the sealing of whole process, also can adopt various suitable seal means to be tightly connected between separation bin 15 and the cooling storehouse 14.
Preferably, in the evaporation concentration treating processes, cooling storehouse 14 also is (maintains static a lot of drawbacks may occur, for example form the internal crystallization ring formation, the concentrated environment of impact) of rotating, and for example cooling off storehouse 14 can be with horizontal rotary cylindrical shell 13 coaxial rotation.More preferably, horizontal rotary cylindrical shell 13 and cooling storehouse 14 can form as one and not have clear and definite boundary to divide, and just horizontal rotary cylindrical shell 13 is regional as evaporation concentration, and cooling storehouse 14 is as the crystallisation by cooling zone.Particularly, described horizontal rotary cylindrical shell 13 and described cooling storehouse 14 structure that forms as one, the first end of this integrative-structure has sealing plate 13a, has water-supply pipe interface and medicine supplying pipe interface on the sealing plate 13a; The second end and the described separation bin 15 of described integrative-structure are tightly connected.Similarly, the rotation of described integrative-structure and the angle on ground are the 2-15 degree, and the height of the described first end of described integrative-structure is lower than the height of described the second end.
Preferably, as depicted in figs. 1 and 2, for the liquid that prevents from not evaporating fully is moved in cooling storehouse 14 and the separation bin 15 (namely leaving the evaporation concentration treatment zone) at the conveying operations of spiral conveying parts 16, can make a little obliquely accumbency setting of horizontal rotary cylindrical shell 13, in other words, can make rotation and the ground of described horizontal rotary cylindrical shell 13 have angle α, and the height that makes the described first end of described horizontal rotary cylindrical shell 13 is lower than the height of described the second end, according to the flow characteristics of the former water of heterogeneity, angle α can be the 2-15 degree.More preferably, can be provided for regulating the parts of the inclined degree of horizontal rotary cylindrical shell 13, thereby adjust easily as required the size of angle α.By this layout that favours ground, unevaporated liquid will reflux under the effect of deadweight and basically all be retained in the horizontal rotary cylindrical shell 13, and can be along with spiral conveying parts 16 move in cooling storehouse 14 and the separation bin 15.
In addition, described spiral conveying parts 16 can comprise driving element, mounting rod and be fixed on a plurality of screw-blades on this mounting rod, described driving element drives described mounting rod rotation, the two ends of described mounting rod are rotatably installed in respectively on the sidewall of described sealing plate 13a and described separation bin 15, extend thereby make spiral conveying parts 16 run through horizontal rotary cylindrical shell 13, cooling storehouse 14 and separation bin 15.
Preferably, the diameter of described a plurality of screw-blades diminishes towards described separation bin 15 gradually from described horizontal rotary cylindrical shell 13.Can further prevent from the liquid in the horizontal rotary cylindrical shell 13 is transported in cooling storehouse 14 and the separation bin 15 together by this layout, can increase the evaporation area of the liquid in the horizontal rotary cylindrical shell 13 simultaneously.
More preferably, the straight line parallel that the lower end of described a plurality of screw-blades is linked to be is in the rotation of described horizontal rotary cylindrical shell 13, and an end of described spiral conveying parts 16 is positioned at the center of described sealing plate 13a.By this layout, because the diameter of a plurality of screw-blades diminishes towards separation bin 15 gradually from horizontal rotary cylindrical shell 13, thereby with respect to horizontal rotary cylindrical shell 13, spiral conveying parts 16 are downward-sloping towards the other end from an end at sealing plate 13a place, thereby can guarantee that spiral conveying parts 16 can not carry liquid basically when the crystallized product with horizontal rotary cylindrical shell 13 bottoms is transported to cooling storehouse 14.In this case, as long as rationally arrange horizontal rotary cylindrical shell 13, cooling storehouse 14 and separation bin 15 radially with the size of length dimension and spiral conveying parts 16, as shown in Figure 1, can make the other end of spiral transferring material parts 16 extend to the bottom of separation bin 15, thereby guarantee that spiral conveying parts 16 can run through horizontal rotary cylindrical shell 13, cooling storehouse 14 and separation bin 15.
When using Horizontal evaporative concentration system of the present invention to carry out evaporation concentration and gas-solid lock out operation, can after the processing of carrying out the scheduled time, from separation bin 15, derive the crystallized product of piling up, and need not to derive continuously crystallized product.For this reason, in embodiment illustrated in figures 1 and 2, the below of described separation bin 15 can be provided with collecting bin 19, but has the interface of folding between described collecting bin 19 and the described separation bin 15.
Here, can between collecting bin 19 and separation bin 15, form described interface by various suitable modes, for example, can form at the diapire of separation bin 15 the first opening, roof at collecting bin 19 forms second opening corresponding with the first opening, and between the first opening and the second opening the dividing plate that can make the first opening and the second open communication or partition is set.Particularly, can make the first opening and the second open communication or partition by extracting out or push dividing plate from the outside, described dividing plate is arranged between the first opening and the second opening pivotly, thereby described dividing plate can be communicated with or cut off by pivoting to realize.Those skilled in the art also can take alternate manner to realize the folding of the interface between collecting bin 19 and the separation bin 15, but all fall into protection scope of the present invention.
In addition, gas-liquid separator 20 can be the gas-liquid separator of various suitable models and structure, and the present invention does not do particular determination.In addition, gas-liquid separator 20 drafts own can guarantee that the inside in horizontal rotary cylindrical shell 13 and cooling storehouse 14 is little negative pressure, with further raising evaporation concentration effect.
In a kind of preferred implementation of the present invention, as shown in Figure 1, described Horizontal evaporative concentration system comprises raw water tubes 30, former water supply pond 40 and working shaft 50, the water side of described raw water tubes 30 and described former water supply pond 40 are separately positioned on the above and below in described cooling storehouse 14, so that former current collect in behind the outside surface in described cooling storehouse 14 in the described former water supply pond 40, described working shaft 50 is provided to described horizontal rotary cylindrical shell 13 with the former water in the described former water supply pond 40 by described water-supply pipe 11.
Be separately positioned on the above and below of cooling off storehouse 14 by water side and former water supply pond 40 with raw water tubes 30, from the water side of raw water tubes 30 through the outside surface in overcooling storehouse 14 and finally collect in the process the former water supply pond 40, between the crystallized product in former water and the cooling storehouse 14 heat exchange occurs at former water.In other words, former water is in the state of relative low temperature, thereby the crystallized product in the cooling storehouse 14 is played cooling effect; On the contrary, crystallized product is in the state of relatively-high temperature, thereby can play pre-heat effect to former water.Be pooled in the former water supply pond 40 and be provided to by working shaft 50 subsequently through the former water of preheating and carry out evaporation concentration in the horizontal rotary cylindrical shell 13, because the former water that is provided in the horizontal rotary cylindrical shell 13 has passed through preheating, thereby can improve the efficient that evaporation concentration is processed.
In addition, the former water that is pooled in the former water supply pond 40 can carry out sedimentation in former water supply pond 40, thereby remove the larger impurity (for example grains of sand) of density in the former water and obtain valuable precipitophore, process cleaning to make as far as possible evaporation concentration, minimizing is safeguarded the cleaning of whole system, and is improved recovery utilization rate.
Because former water can heat up because of contact horizontal rotary cylindrical shell 13, thereby in the process in cooling storehouse 14, evaporation concentration may occur a small amount of former water and the outside surface in cooling storehouse 14 forms crystallized product at former current.The crystallized product that produces in this case may stick on the outside surface in cooling storehouse 14, and along with time lapse may form thicker crystallized product layer, this may cause cooling off the cooling performance decline in storehouse 14 and causing the pre-heat effect of former water undesirable.Therefore, preferably, described evaporation unit also comprises material scraping plate 14a, this material scraping plate 14a is installed in the outside in described cooling storehouse 14, described material scraping plate 14a has the through hole that allows liquid to flow through, thereby allows former water to flow to smoothly in the former water supply pond 40 in the crystallized product on the outside surface of wiping cooling storehouse 14 by material scraping plate 14a off.
Wherein, material scraping plate 14a can adopt high-abrasive material to make, be suitable for the cooling storehouse 14 outside surface between frequent the contact.According to the form that arranges in cooling storehouse 14, material scraping plate 14a is arranged on the appropriate location of the outside of cooling off storehouse 14.For example, in the situation of cooling storehouse 14 with 13 rotations of horizontal rotary cylindrical shell, material scraping plate 14a can be arranged on the fixing position, thereby the rotation by cooling storehouse 14 scrapes off the crystallized product that is attached on the cooling storehouse 14, as shown in Figure 1, material scraping plate 14a can be arranged on the below in cooling storehouse 14.Selectively, also can the outer setting in cooling storehouse 14 can along cooling storehouse 14 circumferentially and with the reverse mobile material scraping plate 14a of the rotation in cooling storehouse 14.
