The breather pipe of scheme 7 records, in each described breather pipe, the voidage of the lateral circle surface of above-mentioned breather pipe is with respect to the whole lateral circle surface of breather pipe, in 1% to 99% scope in scheme 1 to 6.
The voidage of breather pipe lateral circle surface with respect to the whole lateral circle surface of breather pipe, is preferably in 10% to 90% the scope.Then better in 25% to 50% scope.
Voidage can be obtained with following formula.
Voidage (%)=in the breather pipe lateral circle surface, shared area/breather pipe lateral circle surface area * 100, space that the hollow tube of formation breather pipe and the gap of hollow tube form.
In addition, voidage can be set at various values according to the solution amount of accommodating in the size of bubble column, the tower, circulation cycle method of solution etc.
But, if voidage is extremely little, for example be 0% o'clock, through the breather pipe lateral circle surface, the circulation cycle of solution inside and outside breather pipe hindered fully, so be worthless.
On the other hand, voidage is being set at when very big, breather pipe exist density very rare little, can only obtain having same effect in tower with the bubble column that breather pipe is not set, also be worthless.
Consider above-mentioned factor, the voidage of breather pipe lateral circle surface is preferably in the above-mentioned scope.
In this breather pipe, the voidage of breather pipe lateral circle surface is set in the scope that can obtain double effects, and an effect is the soln using breather pipe lateral circle surface of accommodating in the tower, circulation cycle inside and outside breather pipe; Another effect is that the solution of accommodating in the tower is by being located at the space of breather pipe lateral circle surface, the circulation cycle inside and outside breather pipe; So, have the bubble column of this breather pipe, no matter how the liquid level of the solution of accommodating in the tower changes, and can make also that solution carries out circulation cycle in the tower.
In addition, the breather pipe of record in the such scheme 1 to 7, its simple structure, therefore, when it being used for the larger bubbles tower that the operating personnel can enter, constitute all hollow tubes of breather pipe, configurable in the scope that operating personnel's hand can get, so its maintenance activity carries out easily than the breather pipe in the bubble column before.
Here said maintenance activity is meant when producing pore on the hollow tube, carries out the repair by welding operation of pore, perhaps, coil pipe is taken apart, from the manhole that is located at bubble column top, taken out, insert new coil pipe, be welded to connect again, carry out spiral like this and upgrade operation.
Considering the easiness of maintenance activity, constitute the clearance gap of the hollow tube of breather pipe, is to make operating personnel's finger can insert the interval in breather pipe gap at least.
Specifically, be that the operating personnel waits the above interval (be specially and be not less than 2cm) of (normally adult) finger thickness, preferably be not less than the interval (be specially and be not less than 4cm) of palm thickness.
But, being difficult for entering the inside for the operating personnel and carrying out in the bubble column of size of operation, when adopting breather pipe of the present invention, the interval in space is not subjected to the qualification of above-mentioned scope.
The bubble column of scheme 8 records in accommodating the tower of solution, is provided with each described breather pipe in the scheme 1 to 7.
In this bubble column, owing in tower, be provided with the breather pipe of each record in the scheme 1 to 7, so, can irrespectively carry out the running of bubble column with the liquid level of solution height.
In addition, when this bubble column is used for the cultivation of microorganism,, the nutrient solution of accommodating in the tower can be controlled to the temperature that is suitable for the microorganism cultivation most by the heat exchange media that in breather pipe, circulates.In addition, when this bubble column was used for gas absorption operation, no matter the reaction heat that produces when making GAS ABSORPTION liquid absorb gas was under the heat radiation or the situation of heat absorption, can both be controlled at required temperature to the GAS ABSORPTION liquid temp of accommodating in the tower.
Moreover the action effect when having illustrated scheme 1 to 7 described breather pipe as the breather pipe of bubble column above is so the action effect for based on the bubble column of the intrinsic effect of each breather pipe described in first to the 7th scheme no longer describes.
In the bubble column of scheme 9 records, be concentric circles or roughly dispose to concentric circles each described breather pipe in several such schemes 1 to 7.
Said in this specification " roughly concentric circles " is meant to need not to be concentric circles completely that promptly Yuan center needn't be in full accord.
In this bubble column, owing to be concentric circles or roughly dispose to concentric circles each described breather pipe in several such schemes 1 to 7, so, can obtain irrespectively efficiently to carry out the effect of the running of bubble column with the liquid level of solution height; And, can be by the heat exchange media that in several breather pipes that disposed, circulates respectively, the solution of accommodating in the tower efficiently is controlled at temperature required, and, can guarantee the bigger advantage of heat transfer area of unit volume in addition.
The bubble column of scheme 10 record, in scheme 8 or 9 described bubble column, each described breather pipe in the scheme 1 to 7, its area of section account for bubble column the tower area of section 10% to 90%.
In addition, when being concentric circles or roughly disposing several breather pipes to concentric circles, " area of section of breather pipe " is meant the area of section of the breather pipe of outermost layer position.
In this bubble column, circulation cycle efficiently inside and outside the breather pipe that the solution of accommodating in the tower is provided with in tower circulates in breather pipe at heat exchange media, the solution of accommodating in the tower efficiently can be controlled at required temperature.Therefore, when this device is used for the cultivation of microorganism, can efficiently cultivate with optimal condition.In addition, when this device is used for gas absorption operation, can carry out the gas swap operation effectively.
The bubble column of scheme 11 records, in each described bubble column, the lower position at breather pipe has distributor in scheme 8 to 10.
In this bubble column, because the lower position of the breather pipe of each record in scheme 1 to 7, be provided with distributor, so, when for example being arranged on distributor in the zone of breather pipe, the bubble that can supply with in the solution of the inboard existence of breather pipe, more than what supply with toward the solution between the breather pipe outside and the tower, so, in the inboard solution that exists of breather pipe, produce from the below toward the liquid stream of top; In the solution that between the breather pipe outside and tower, exists, produce from the top toward the liquid stream of below.Therefore, in the solution in tower, can produce and utilize the circulation cycle breather pipe lateral circle surface, that breather pipe is inside and outside.Moreover, also can produce circulation cycle space by being located at the breather pipe lateral circle surface, inside and outside the breather pipe.
Otherwise, if the zone that distributor is arranged on breather pipe when outer, outside breather pipe and the supply of the solution between tower bubble, more than what in the solution of breather pipe inboard, supply with, therefore, in the solution that between the breather pipe outside and tower, exists, produce from the below toward the liquid stream of top; In the inboard solution that exists of breather pipe, produce from the top toward the liquid stream of below.Therefore, in the solution of in tower, accommodating, produce utilize the breather pipe lateral circle surface, the inside and outside circulation cycle of breather pipe.Moreover, also can produce by being located at circulation cycle space on the breather pipe lateral circle surface, inside and outside the breather pipe.
In this bubble column, in the solution of accommodating in the tower, can produce 2 circulation cycle, that is, as mentioned above, utilize the circulation cycle of breather pipe lateral circle surface, be located at the circulation cycle in the space on the breather pipe lateral circle surface with utilization, so no matter how the liquid level of the solution of accommodating in the tower changes, and can stir the solution of accommodating in the tower.
In addition, also can dispose the distributor that to supply with bubble the while to the breather pipe inboard and the outside.At this moment, though the circular flow in the bubble column is irregular, can improve the contacting efficiency of gas-liquid.
The bubble column of scheme 12 records, in the bubble column described in the scheme 11, when overlooking the tower of accommodating solution, above-mentioned distributor is arranged in the zone of each described breather pipe in the scheme 1 to 7.
Here said " when overlooking the tower of accommodating solution; distributor is arranged in the zone of breather pipe ", be meant breather pipe of the present invention, be set to several concentric circles or roughly during concentric circles, when overlooking the tower of accommodating solution, distributor the position is set, so long as in the zone of outermost layer breather pipe, then can be in the zone of innermost layer breather pipe, also can be to the position between the outermost layer breather pipe zone in innermost layer breather pipe zone.
The position (highly) of the vertical direction of distributor is set, and can be any height, gets final product so long as be lower than the position of breather pipe upper end.
In this bubble column, in tower, supply with bubble the solution, owing to the bubble of in the solution of breather pipe inboard, supplying with from distributor, more than what supply with toward the solution between the breather pipe outside and the tower, so, in the inboard solution that exists of breather pipe, be created in the tower from the below toward the liquid stream of top; In the solution that between the breather pipe outside and tower, exists, be created in the tower from the top toward the liquid stream of below.Therefore, in the solution of in tower, accommodating, can produce and utilize the circulation cycle breather pipe lateral circle surface, that breather pipe is inside and outside.
Moreover, also can produce by being located at circulation cycle space on the breather pipe lateral circle surface, inside and outside the breather pipe.
Therefore, in this bubble column, in the solution in the tower, can produce 2 above-mentioned circulation cycle, so no matter how the liquid level of the solution of accommodating in the tower changes, and can stir the solution of accommodating in the tower.
The bubble column of scheme 13 records, in the bubble column described in the scheme 11, when overlooking the tower of accommodating solution, the distributor of bubble column is arranged on outside the zone of scheme 1 each described breather pipe in 7.
Here said " when overlooking the tower of accommodating solution, distributor is arranged on outside the zone of breather pipe " is meant breather pipe of the present invention, be set to several concentric circles or roughly during concentric circles, when overlooking the tower of accommodating solution, distributor the position is set, outside the zone of outermost layer breather pipe.
The position (highly) of the vertical direction of distributor is set, and can be any height, gets final product so long as be lower than the breather pipe upper end.
In this bubble column, supply with bubble from distributor solution in tower, owing to the bubble of in the solution of breather pipe inboard, supplying with, than lacking of supplying with toward the solution between the breather pipe outside and the tower, so, in the solution of breather pipe inboard, produce from the top toward the liquid stream of below; In the solution between the breather pipe outside and tower, produce from the below toward the liquid stream of top.
Therefore, in the solution in tower, can produce and utilize the circulation cycle breather pipe lateral circle surface, that breather pipe is inside and outside.
Moreover, also can produce by being located at circulation cycle space on the breather pipe lateral circle surface, inside and outside the breather pipe.
Therefore, in this bubble column, in the solution of accommodating in the tower, 2 above-mentioned circulation cycle can be produced,, the solution in the tower can be stirred so no matter how the liquid level of the solution of accommodating in the tower changes.
The specific embodiment
Below, with reference to description of drawings breather pipe of the present invention, distributor and have the preferred mode of their bubble column.
(working of an invention mode 1~4)
In the embodiments of the present invention 1~4, the example that is provided with 1 breather pipe in tower is described.
(working of an invention mode 1)
Fig. 1 is the biopsy cavity marker devices oblique view of the routine bubble column of one of the present invention.
Fig. 2 is the sectional drawing that bubble column shown in Figure 1 represented in summary.
Fig. 3 is that cross-sectional view bubble column, that look down from the top shown in the III-III line cut away view 1 in Fig. 1 represented in summary.
This bubble column 1 as shown in Figure 1, has and accommodates nutrient solution or GAS ABSORPTION and take the training 2 of liquid, be located at breather pipe 3, distributor 4 in the tower 2.Distributor 4 is arranged on the below of the breather pipe 3 in the tower (tank body) 2.
Among Fig. 1,2a represents the lid of tower (tank body) 2.2h represents to be located at as required the aspirating hole on the lid 2a.Parts are represented drainpipe shown in 6.In addition, parts are represented pillar shown in 5, and this pillar 5 is used for breather pipe 3 is installed in the tower 2.
In this bubble column 1, breather pipe 3 uses the breather pipe that is formed and had space S3 by hollow tube on its whole lateral circle surface.
Say more definitely,, use the breather pipe that hollow tube is wound into helical form and forms as breather pipe 3.
Constitute the material of the hollow tube of breather pipe 3, it is far away not have special limit, so long as be used for being installed in common bubble column breather pipe material can, for example can adopt metal, resin etc.
This bubble column 1 is used for cultivation when operation of microorganism, before cultivating operation, for to carrying out sterilization in the tower 2, be to carrying out boiling in the tower 2.
So, consider when wanting boiling, constitute the material of the hollow tube of breather pipe 3, preferably can stand the material of boiling, so, preferably adopt metal in this case.
Metal can adopt stainless steel, aluminium, iron etc., normally used metal all can, but stainless steel preferably.
In addition, when this bubble column 1 for example is used for the gas swap operation, exposing to the open air in will tower 2 under the situation under the hot conditions of boiling etc., constitute the material of the hollow tube of breather pipe 3, also can be resin.
Form the diameter of the hollow tube of breather pipe 3, can embrace the application target of tower 1, the size of bubble column 1 etc. according to gas and freely select, still, normally in the scope of 5mm to 200mm, be preferably in the scope of 50mm to 100mm.
Breather pipe 3 transverse shapes get final product so long as can play the shape of breather pipe effect, and are normally circular, but are not limited to circle, also can be the polygons of ellipse, triangle or quadrangle etc.
Breather pipe 3 forms between hollow tube and hollow tube the space.
The interval in the space between this hollow tube and the hollow tube need not at breather pipe necessarily on the whole, as long as when using as breather pipe, breather pipe the solution inboard and outside is exchanged visits get final product.
The interval in the space between hollow tube and the hollow tube, though be not particularly limited,,,, then more convenient if leave the interval that can keep in repair for the bubble column of manufacturing equipment height.The bubble column of 5~1000L capacity of using except laboratory research, this interval is operator's the finger interval that can enter normally, promptly is not less than 2cm.
If the voidage of breather pipe 3 lateral circle surfaces is excessive, though the inside and outside solution contact free degree of breather pipe improves, but, as breather pipe 3, the effect of its mixed performance etc. reduces, perhaps as described later, also reduce as the surface area (heat transfer area) of mesospore pipe heat-exchange device, that constitute breather pipe 3.
Otherwise, when the voidage of breather pipe 3 lateral circle surfaces is too small, though the surface area of hollow tube (heat transfer area) increase,, the free degree of solution contact reduces.
Consider these factors, the voidage of breather pipe 3, is preferably in 10% to 90% the scope if then better in 1% to 99% scope with respect to the breather pipe lateral circle surface, and is then better in 25% to 50% scope.
This breather pipe 3, because the existence in lateral circle surface space, under situation about this breather pipe 3 being installed to 2 in, no matter the liquid level of the solution of accommodating in the tower 2 is in any height, what solution also can be at breather pipe 3 is inside and outside mobile.
Hollow tube is wound into helical form, constitutes breather pipe 3, lead in this hollow tube owing to heat can be joined Media Stream, so breather pipe 3 also can play the effect of heat-exchange device.
In this example, expression makes heat exchange media flow to other end 3b from an end 3a of breather pipe 3, still, also can make heat exchange media flow to an end 3a from other end 3b.
When using bubble column 1, under the situation of the solution heat radiation in the bubble column 1, cold-producing medium is passed through in the breather pipe 3; Under the situation of the solution heat absorption in the tower 2, hot media is passed through to get final product.Heat exchange media is water preferably, but also can be the material beyond the water, so long as all can as the material of the distant normal use of heat exchange media.
Below, illustrate in greater detail in this bubble column 1 structure of the breather pipe 3 that uses.
Fig. 4 is the breather pipe 3 local ideographs that amplify that adopt in this bubble column 1; Fig. 4 (a) is an oblique view, is illustrated in to pattern in the operation of assembling breather pipe 3 state before certain hollow tube that constitutes breather pipe 3 is connected with other hollow tube; Fig. 4 (b) is an oblique view, is illustrated in to pattern in the operation of assembling breather pipe 3, certain hollow tube of formation breather pipe 3 and state after other hollow tube is connected.
The hollow tube that uses in this bubble column 1, constitute breather pipe 3 can be monolithic molding product, but when the size of breather pipe 3 was big, the making of the breather pipe 3 of formed products was just compared difficult as a whole.
In this bubble column 1, as shown in Figure 4, use welding manner, the hollow tube P3 that constitutes breather pipe 3 ... be connected with each other.
In addition, interval this bubble column 1, that constitute the hollow tube of breather pipe 3, at least be the interval (gap (specifically being not less than the interval of 2cm) that is equivalent to operator (normally adult) finger thickness) that finger can insert, the interval (the above interval of 4cm specifically) that preferably is equivalent to palm thickness, like this, when any one the generation pore in the some hollow tubes that constitute breather pipe 3, can easily repair this pore part.
Below, the structure of distributor 4 is described.
In this bubble column 1, several arms 4b... that distributor 4 has main 4a and branches out from main 4a.
Among Fig. 1,4c represents gas supply port.
At main 4a and several arms 4b ... each above the pipe, form several through holes.
In this bubble column 1, when overlooking the tower 2 of accommodating solution, constitute main 4a and several arms 4b of distributor 4, be located in the zone of breather pipe 3.
Below, the using method and the action of this bubble column 1 are described.
When carrying out the cultivation of microorganism with this bubble column 1, collecting post's cultured microorganism and nutrient solution in tower 2 are sent into the gas of air etc. in the tower 2 from distributor 4.
When in tower 2, cultivating microorganism, the solution superheated of accommodating in tower 2 when fermentation fever is to being suitable for temperature that microorganism cultivates when above, being wound in the spiral helicine hollow tube of formation breather pipe 3, flow through the refrigerant body of cooling water etc., the temperature of the solution of accommodating in the tower 2, be adjusted to the temperature that is suitable for this microorganism cultivation.
In addition, when in tower 2, cultivating microorganism, when the solution temperature of accommodating in the tower 2 is cultivated when temperature required far below microorganism, being wound in the spiral helicine hollow tube of formation breather pipe 3, flow through the hot media of warm water etc., the temperature of the solution of accommodating in the tower 2, be adjusted to the temperature that is suitable for this microorganism cultivation.
In addition, when carrying out the GAS ABSORPTION operation with this temperature tower 1, accommodate the GAS ABSORPTION solution that is used to absorb object gas in tower 2, from distributor 4 supply gas, this gas contains the gas that is absorbed with solution by the GAS ABSORPTION of accommodating in the tower 2.
Certain composition during making the GAS ABSORPTION usefulness solution gas supplied of in tower 2, accommodating from distributor 4, when being absorbed with solution by this GAS ABSORPTION, under the situation of heat absorption, toward being wound in the spiral helicine hollow tube of formation breather pipe 3, the hot media of circulation hot water etc., otherwise, under the situation of heat radiation, for the GAS ABSORPTION of accommodating in the tower 2 is cooled off with solution, toward being wound in the spiral helicine hollow tube of formation breather pipe 3, the refrigerant body of circulation cooling water etc. reduces the temperature of the latent liquid of accommodating in the tower 2.
In this bubble column 1,, use hollow tube is wound into the breather pipe that spiral is received as the breather pipe 3 that is located in the tower 2, so, molten when being accommodated in the tower 2, the solution of accommodating in the tower 2, by being wound into the gap of spiral helicine hollow tube, can be in the inside and outside circulation cycle of breather pipe.
Like this, if adopt this bubble column 1, no matter accommodate in the tower 2 molten be which kind of state by liquid level, can carry out the cultivation of microorganism or the absorption of gas etc.
As mentioned above, in this bubble column 1, in tower 2, be provided with hollow tube is wound into spiral helicine breather pipe 3, so, by heat exchange media (refrigerant body or hot media) circulation is constituted in the hollow tube of breather pipe 3, can remain on optimal temperature to the solution that is housed in the tower efficiently.
Moreover, because in this breather pipe 3, constitute the solution of accommodating in whole or whole approximately circumferential lateral surface and the tower 2 of hollow tube of breather pipe 3 and contact, so heat transfer area is big.Therefore, during the heat exchange media that circulates in breather pipe 3 (refrigerant body or hot media), the heat-exchange capacity in heat exchange media and tower between the solution is good.
In addition, in this embodiment, when overlooking breather pipe 3, the nozzle arrangement of distributor 4 is (see figure 3) in the zone of breather pipe 3, so, when when distributor 4 is sent into the gas of air etc. in the tower 2, overlook under the situation of breather pipe 3, the bubble of supplying with toward the inboard solution that exist of breather pipe 3, than toward breather pipe 3 outside and the supply of the solution between the tower 2 many, and can supply with equably.
Like this, apparent specific gravity at the breather pipe 3 inboard solution that exist, apparent specific gravity than the solution that exists between breather pipe 3 outsides and tower 2 is little, in the breather pipe 3 inboard solution that exist, be created in the tower 2 from the below towards the liquid stream of top, in the solution between breather pipe 3 outsides and tower 2, be created in the tower 2 from the top towards the liquid stream of below.
In addition, in this bubble column 1, except above-mentioned in tower vertically by the stream, the gap of the hollow tube by constituting breather pipe 3 is contained the solution of bubble from the inboard of breather pipe 3 towards breather pipe 3 flows outside, thereby is produced the liquid stream of horizontal direction.Because the liquid stream that produces this vertical direction becomes the stream of the solution of one integrated mass with the liquid stream of horizontal direction, so, for example compare with bubble column before 301 shown in Figure 21, the liquid of taking of accommodating is fully mixed.This in tower 202 of bubble column 301, is provided with the breather pipe 303 of drum before.
This result as if adopting this gas ground tower 1, compares with the situation that adopts the bubble column 301 that cylindric breather pipe 303 is set before in tower 202, can and carry out the cultivation of microorganism efficiently, and, the supply capacity of raising tower 2 interior solution supply oxygen etc.
Like this, can make this bubble column 1 simple structure, big as the heat transfer area of the breather pipe of heat-exchange device, so, be particularly suitable as scale-up large-scale, the i.e. highly big bubble column of its scale.
