Description
Technical field
The present invention relates to a kind of continous way Magnetic Isolation equipment, be suitable under normal temperature, the condition of normal pressure, be more suitable in the separation of the molecule of high temperature, condition of high voltage and weak magnetic.
Background technology
Magnetic separation technique not only is widely used in the sewage disposal in mineral processing, steel plant and power plant, and be the Selective Separation problem of the particle system in the coal industry, nonmetal industry, atomic energy industry, chemical industry especially biotechnology, effective solution route is provided.In biochemical separation processes, magnetic separation technique is compared with other isolation technics has many potential advantages, is biochemical important development direction of separating.
When magnetic-particle is a micron-scale and more during large scale, its Magnetic Isolation operation is less demanding to magnetic field intensity and gradient, and Magnetic Isolation process and device design than being easier to.For the separation of the magnetic-particle of nano-scale, its lock out operation is difficulty relatively, requires Magnetic Isolation equipment to have very high magnetic field intensity and gradient; Moreover the separation of the weak magnetic-particle of some micron-scales also needs magnetic separating apparatus to have very high magnetic field intensity and gradient.To introduce magnetic matrix is that to separate (HGMS) technology be a kind of very effective method for the High-gradient Magnetic of feature.
The High-gradient Magnetic isolation technics has obtained application widely in mineral processing, in biochemical the separation at present.High gradient magnetic separating apparatus mainly contains two classes: periodic high gradient magnetic separating apparatus and continuous high gradient magnetic separating apparatus.The periodic high gradient magnetic separating apparatus mainly is made up of the tank body of a filling steel wool medium, and this tank body is twined by the solenoid of energising.Feed liquid to be separated is by the magnetizing mediums in the tank body, and the magnetic component in the feed liquid is owing to the effect that is subjected to magnetic field force is trapped on the magnetizing mediums, and non magnetic component is then passed through tank body.Operation a period of time stops feed liquor, and outage makes the magnetic field removal, washes.Flushing finishes, and continues feed liquor, realizes capturing, so formula operation performance period.The shortcoming that it exists is: use electromagnet, can not produce high magnetic field intensity, to producing difficulty separating of ultra-fine grain and weak magnetic-particle; Intermittent operation, separative efficiency is low.Another kind of continuous high gradient magnetic separating apparatus mainly is made up of rotating separation ring (being made up of some separation chamber) and fixed energization solenoid.Feed tube and wash tub pipe are arranged above separation ring successively.During operation, separation ring rotates, and separation chamber through fixing energization solenoid, carries out feed liquor and flushing operation successively simultaneously, realizes the continous way operation.But the shortcoming that it exists is: use electromagnet, can not produce high magnetic field intensity; Separation chamber can not seal, and can not carry out the lock out operation of high temperature, high pressure and volatile liquid.
In sum, there is following problem in present high gradient magnetic separating apparatus in practice:
1, high gradient magnetic separating apparatus is the batch (-type) flow operation mostly, the magnetic-particle granularity is little in separation system, content is big, require Magnetic Isolation efficient height, intermittent operation causes effective disengaging time in each operation cycle very short, treating capacity is lower, and in order to improve separating power, it is necessary setting up the separation of continuous high gradient magnetic.
2, separate in High-gradient Magnetic and catch and discharge in two blocked operation processes, requirement acts on background magnetic field in the magnetizing mediums separation chamber and can apply with removal and switch, though this operation of high-speed double electromagnet is convenient, but power consumption is huge, the device structure complexity, need to be equipped with cooling system, the low disadvantage that becomes in its use of the magnetic field intensity that operation and maintenance cost height, especially electromagnet produce.The permanent magnetism physical efficiency produces high magnetic field intensity, has reliable operation, and price is lower, does not need auxiliary device, and operation maintenance is convenient, and advantages such as saves energy come into one's own and develop, but magnetic field handover operation difficulty relatively.
3, present high gradient magnetic separating apparatus generally only is applicable to the separation of low temperature, low pressure and normal temperature, condition of normal pressure magnetic particle, these devices are as Chinese patent " isolating the continuous high gradient magnetism separate method and the device of magnetic-particle from the fluid " patent No. 99107814.4, " continuous separation device that is used for the ultra-fine magnetic-particle of catalyzing dehydrogen desulfurization " patent No. 01120631.4.But the separation to high temperature, condition of high voltage magnetic particle is met difficulty.
Therefore, how to solve the problems referred to above that high gradient magnetic separating apparatus exists in application and become the key that enlarges the high gradient magnetic separating apparatus range of application.
