Description
Technical field
This utility model belongs to post processing circulation conveying technology field, is specifically related to the vortex diode pump that a kind of chamber height blade diameter length ratio is constant.
Background technology
Spentnuclear fuel reprocessing plant process material liquid mode of movement mainly adopts dosing pump, steam jet pump and air lift.In use have also discovered these conveying equipments and there is certain limitation.Dosing pump does not possess freedom from repairs function, and the maintenance frequency is high.Steam jet pump then can affect its amount of infusion because the steam used makes conveyer device temperature raise, and can cause not feeding, and the condensed fluid of steam can dilute feed liquid original concentration time serious.When air lift uses, air and feed liquid are directly fully contacted, it is necessary to efficient air cleaning system matches, it is necessary to higher submergence degree, delivery head is limited, and unimpeded is indifferent.Utilize RFD and the vortex diode pump of fluidics, be respectively provided with that flow is big, lift is high, do not dilute or add the feature that hot liquid, gas are not fully contacted with liquid, can process slurry radioactive fluid.In general, vortex diode pump can carry bigger solid particle, and operating efficiency is higher, and RFD is more easily done big flow and high-lift, and processing is relatively low with mounting cost.Both new pump some nuclear facilities abroad is widely applied, such as Celafil moral factory site and the waste treatment plant of the U.S. of Britain；At present, owing to being protected factor to affect by business, the research data that abroad can inquire also cans be counted on one's fingers, and causes China's research and application also in the starting stage.
The 404 Ltd., CNNC's power reactor spentnuclear fuel post processing middle experiment factory (abbreviation pilot plant) is according to production scene needs, carry out the applied research of vortex diode pump, in order to solution is put the conveying of vapo(u)rization system high salt sub-material liquid and easily blocks the specialized fluids transportation problem such as pipeline, the uranium tail end high concentration uranium feed liquid metering frequent not feeding of transport pump.
Vortex diode pump is as the core devices of vortex diode pumping system, and its overall structure is relatively simple, is made up of a flattened cylindrical shape cavity and tangential pipe, tube axial；In fluid delivery process, fluid is via vortex diode pump, the flow resistance that can produce significant difference from positive and negative both direction flowing.Wherein, during forward flow, namely fluid enters vortex cavity from tube axial, after the resistance being subject to similar two 90 degree of elbows, goes out from tangential pipe flow, and Pressure Drop is relatively small, and namely fluid total energy loss is less；During reverse flow, namely fluid enters vortex cavity from tangential pipe, under the constraint of cavity wall, form one retrain thin cylinder eddy current, and (the free vortex flow stage in forced vortex stage of the free vortex flow stage that successively experience is peripheral and immediate vicinity, along half radial direction center position, fluid tangential velocity is gradually increased, static pressure is gradually lowered；In the forced vortex stage, along half radial direction center position, tangential velocity and static pressure reduce simultaneously, and fluid gross energy is also down to minimum therewith), energy loss relatively big (namely reverse flow resistance is bigger) in the process.According to the characteristic that forward and reverse flow resistance difference is bigger, the fluid conveying of vortex diode pump is made to have corresponding superiority.But existing vortex diode pump fluid feed flow and efficiency are all relatively low.
Summary of the invention
The purpose of this utility model is in that the vortex diode pump providing a kind of chamber height blade diameter length ratio constant, it is possible to increase fluid feed flow and efficiency.
The technical solution of the utility model is as follows: the vortex diode pump that a kind of chamber height blade diameter length ratio is constant, this vortex diode pump includes vortex cavity, tube axial and tangentially manages, wherein, wherein, the vortex cavity of flattened cylindrical barrel structure is bored section by convergent in the axial direction and is connected with tube axial, and vortex cavity is bored section by convergent in the tangential direction of cylindrical structure and is connected with tangential pipe；Diameter circular in tangential direction inside vortex cavity is constant with the aspect ratio on axis direction；Tube axial, tangential pipe and the size of convergent cone section match with the size of vortex cavity.
Inside described vortex cavity, the constant height on axis is at 15mm～25mm.
Aspect ratio on diameter circular in tangential direction inside described vortex cavity and axis direction is constant between 4～6.
Diameter circular in tangential direction inside described vortex cavity is 5 with the aspect ratio on axis direction.
Described vortex cavity inwall is that circular arc type is without dead band.
Remarkable result of the present utility model is in that: the constant vortex diode pump of a kind of chamber height blade diameter length ratio described in the utility model is when raising high 10m, admission pressure 0.4MPa, and the fluid feed flow of the vortex diode pump of footpath, chamber 100mm is increased to 1335.7L/h by initial 900L/h, efficiency is increased to 54.7% by 28%；Carry in test in the feed liquid containing solid particle, feed flow is about 900L/h, the response rate of solid particle reaches more than 95%, and do not retain in pump, deposition of solid particle, overcome the limitation of other mechanical pump, air lift, steam jet pump, there is the conveying powerful advantages containing solid particle feed liquid.
