Description
Technical field
The utility model relates to the experimental provision of a kind of biphase gas and liquid flow, bubble dynamics, particularly relates to a kind of detachable experimental provision for the research of multiple row bubbling behaviour.
Background technology
Gas liquid two-phase flow and bubbling behaviour are extensively present in heat energy power mechanism, chemical machinery, the flowing of meeting influential system, heat transfer characteristic.Therefore, experimental study is carried out to the behavior of gas liquid two-phase flow and bubble and there is important engineering significance.At present, Chinese scholars has carried out a large amount of experimental studies to gas liquid two-phase flow and bubbling behaviour, but be all mainly concentrate on single-row bubble in gas liquid two-phase flow or bubbling behaviour, the experimental provision carrying out studying for multiple row bubbling behaviour is less.What University Of Tianjin Wang Hong mono-adopted is the visual bulge test unit simulation Two-Phase Flow Field (Wang Hongyi " underwater bubble image processing method and kinetic characteristic research ") of a set of vertical placement, though its energy simulate Two-Phase Flow Field and bubbling behaviour, but single-row bubble can only be produced, the research of multiple row bubble can not be used for.The experimental provision (E.Camaras. " Influence of coalescence behaviour of the liquid and of gas sparging on hydrodynamics and bubble characteristics in a bubble column ") of the E.Camaras of Laboratoire des Sciences du Ge ' nie Chimique is although can simulate multiple row bubble, but its defect is: the bubble produced for generation of the bubbler of bubble in (1) its experimental provision is disorderly and unsystematic, be not easy to the growth studying multiple row bubble, formed, interaction between form and bubble, (2) its pitch-row of not determining of bubble produced and pitch of holes, be not easy to study the interaction between different condition bubble, (3) alternative costs of its experimental provision replacing bubbler are high.
Summary of the invention
The purpose of this utility model is that a kind of structure is simple in order to provide, applied range, multiple row can be produced, have determining hole apart from and the detachable experimental provision for the research of multiple row bubbling behaviour of bubble of pitch of holes.
The purpose of this utility model is achieved in that and comprises water tank, feeder and pipeline, also comprise removable organic glass joint and the pneumatic joint for connecting tube and pore, below described water tank, boss is set, boss through hole is set and through hole with internal thread, removable organic glass joint surface external thread is set and with described screw-internal thread fit, removable organic glass joint arranges the pore run through up and down, in the pore position of removable organic glass joint lower surface, the female mounting hole of tool is set, pneumatic joint is arranged in the female mounting hole of described tool, have two described pores at least, the corresponding female mounting hole of tool, pneumatic joint and feeder also have two at least.
The utility model also comprises some architectural features like this:
1. feeder described in comprises and connects air pump, flow control valve, glass rotameter and non-return valve with pipeline successively from initial end, and the output terminal of non-return valve is connected with pneumatic joint by pipeline.
Compared with prior art, the beneficial effects of the utility model are: the utility model adopts removable organic glass joint, the boss arranged by water tank bottom is coordinated with removable organic glass joint, can realize changing whole experimental provision, and only need change different organic glass joints and (process in standardized removable organic glass joint process and there is different stomatal numbers, aperture, the joint of pore spacing), just different pore size can be simulated, different pitch of holes, and generation that is single-row and multiple row bubble, depart from, the behaviors such as rising, there is applicable scope wide, the operating mode of simulation is many, low cost and other advantages, removable organic glass joint of the present utility model and water tank screw up installation by screw thread, easy for installation, pipeline and removable joint adopt pneumatic joint to be connected, and can prevent the leakage of liquid in water tank, get rid of the error because leak of liquid brings experimental result, the gas flow that air pump produces is adjustable, and in flowmeter and air pump, flow control valve is housed, and realizes the fine setting to gas flow, can complete the air and liquid twophase flow experiment under gas with various flow.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Composition graphs 1 to Fig. 6, a kind of detachable experimental provision for the research of multiple row bubbling behaviour provided by the utility model comprises water tank 1, feeder and pipeline, also comprise removable organic glass joint 3 and the pneumatic joint 5 for connecting tube and pore 11, below described water tank 1, boss 2 is set, boss 2 through hole is set and through hole with internal thread 13, removable organic glass joint 3 surface arranges external thread 14 and coordinates with described internal thread 13, removable organic glass joint 3 external diameter is equal with boss 2 internal diameter, also namely removable organic glass joint 3 is screwed up by external thread 14 and realize the connection with water tank 1 on boss, removable organic glass joint 3 is arranged the pore 11 run through up and down, pore 11 is equivalent to gas flow 4, in pore 11 position of removable organic glass joint 3 lower surface, the female mounting hole 12 of tool is set, pneumatic joint 5 is arranged on the female mounting hole of described tool 12 li, and pneumatic joint 5 can prevent leak of liquid in water tank 1.
The utility model is the behavior in order to study multiple row bubble, therefore, described removable organic glass joint 3 have two pores 11 at least, the corresponding female mounting hole 12 of tool, pneumatic joint 5 and feeder also have two at least, to realize the research of multiple row bubbling behaviour, but the spacing between pore quantity and pore will be arranged according to the size reasonable of removable organic glass joint.Utilize the pore 11 be arranged on removable organic glass joint 3 can generate the multiple row bubble of pitch-row and the pitch of holes having and determine.
Feeder comprises uses pipeline air pump 9, flow control valve 8, glass rotameter 7 and non-return valve 6 successively from initial end, air pump 9 is connected with AC power 10, the output terminal of non-return valve 6 is connected with pneumatic joint 5 by pipeline, to connect non-return valve 6 in pipeline connects, prevent the liquid in water tank from flowing backwards.By regulating the size of gas flow in the preliminary Control release of air pump 9, can finely tune with flow control valve 8 to flow, flow counting is read by glass rotameter 7.The replaceable range of flowmeter 7, small-range flowmeter counting region is 16-160mL/min, and Mass Flow Meter counting region is 160-1600mL/min.
In specific implementation process of the present utility model, can process to first standardization same external diameter removable organic glass joint several, experimentally require on removable organic glass joint 3, bore pore 11 and the corresponding female mounting hole 12 of tool, the organic glass joint of different pore size, pitch of holes can be changed according to demand, the experiment of different types of bubbling behaviour research that whole experimental provision can realize requiring can be changed, comprise the multiple row bubbling behaviour of simulation different pore size, different pitch of holes.In the position at pore 11 place of the upper surface of removable organic glass joint 3, can boss be set, the bubbling behaviour had with a certain distance from water tank bottom can be observed like this.
