Both ends of the separating column are provided with flanges used for connecting with other reactors. The utility model belongs to a separation device in process in the industries of medicine, chemical industry, and metallurgy and so on, and is in particular applicable for separation of liquid and solid containing magnetic substance. For instance, the utility model is used for separating granular nickel catalyst after hydrogenation reaction from solution. The utility model is operated simply, has reliable performance and is highly automatic. By using the utility model, the work area is kept clean. The content of granules of catalyst in products can meet different indices.
Description
Technical field
The utility model relates to a kind of electromagnetic separator, belongs to and is used for the equipment that technology is separated in the industries such as medicine, chemical industry, metallurgy.Gu be specially adapted to contain the liquid-separation of magnetisable material.
Background technology
In chemical industry, the catalytic reduction technology has developed into that the world today generally adopts and very economic production technology, and for example it has received more satisfactory effect with the production of Yushan Hill plough alcohol.The technology that D/W catalytic reduction in the suspension catalytic reactor generates mountain plough alcohol mainly is divided into intermittently at present, continuous two kinds of technological processes.Batch process generally adopts the 3-10Mpa hydrogenation pressure, carries out in autoclave intermittently, adds D/W, and under the catalysis of aluminium/nickel alloy, pH value 6.5-7.5,150-160 ℃, 3.5-5.0Mpa pressure feed hydrogen down and carry out hydrogenation reaction.When hydrogenation reaction reaches terminal point, carry out sedimentation and filtration (or plate compression), isolate catalyst, remove heavy metal through ion-exchange again.Being evaporated to finite concentration promptly gets the liquid mountain and ploughs pure product.Evaporation and concentration is during to 78-80% concentration, and crystallisation by cooling separates and promptly gets the solid crystal product again; Continuity method generally adopts the hydrogenation pressure of 14-20Mpa to carry out continuous catalytic hydrogenation in tubular reactor.The same batch process of subsequent handling.Domestic most employing batch process is produced.
No matter be continuously or the Batch Process flow process, all contain a large amount of catalyst in the mountain plough alcohol behind the catalytic hydrogenation.Domestic production producer mainly uses aluminium/nickel alloy as hydrogenation catalyst, and catalyst must separate with product in the production process, and the catalyst after the separation not only can purified product, and can reclaim noble metal nickel.Plough alcohol in mountain mainly contains methods such as settling methods, mechanical filter method with the separation method of catalyst at present.
1, settling methods
Be by means of gravity a kind of method of catalyst separation, the simple easy operating of equipment, the not only easy sedimentation of bulky grain, and granule also can reach the effect of precipitation by cohesion or flocculation, thereby use wider.Shortcoming is that settling apparatus many (20 stainless steel settling tanks of 2000 tons of/year needs) floor space is big, and the sedimentation time is slow, is subjected to condition influence such as temperature, viscosity, and is bigger with the operating condition fluctuation;
2, mechanical filter method
Adopt mechanical means such as centrifugal or sheet frame to filter, this method reduced investment, simple to operate, but temperature is higher when filtering in process of production, operating condition is abominable, runs material, leaks and expect that phenomenon is serious, and granule should not filter, and product is exposed in the air for a long time, influences product quality.
More than also must connect ion-exchange process in two kinds of method technologies, could guarantee out that qualified mountain ploughs pure product, whole process complexity, and since in two kinds of methods thinner catalyst granules can't remove, not only make ion exchange column shortening in service life, be not suitable for the big requirement of producing of modernization.
The content of invention
Goal of the invention of the present utility model is to provide a kind of electromagnetic separator, in the production technology of particularly suitable Yushan Hill plough alcohol, can replace present production method, has reduced equipment investment and simple to operate, dependable performance.
Goal of the invention of the present utility model realizes in the following manner.A kind of electromagnetic separator comprises in the structure splitter of tubular hugging yoke in the outside of splitter that the outer felt of splitter is provided with perforated baffle around coil in the splitter, filler is housed in the post.
Easy for installation in order to process, the yoke in the splitter outside can be made two.
The coil in the splitter outside is wrapped in the outside of yoke, can realize same effect.
Filler in the splitter uses Ball-type packing, and separating effect is better.
The utility model is compared the beneficial effect of obtaining and is with conventional art: can make separation process realize totally-enclosed continued operation, and can realize microcomputer automatic control, thereby improved labor productivity, the products of separated steady quality, can also prolong the service life of follow-up ion exchange column, owing to used the backwash technology, helped the recovery of catalyst.
Operation principle of the present utility model is an example to separate mountain plough alcoholic solution.Alternating current is obtained direct current after by the dc source rectification; produce high-gradient magnetic field through behind the coil; allow the mountain plough alcoholic solution that contains catalyst granules by the electromagnetism splitter; because of containing, Raney nickel is magnetic; then when mountain plough alcoholic solution passes through the electromagnetism splitter; the Raney nickel particle substantially all is attracted on the filler of electromagnetism splitter; when the electromagnetism splitter reaches capacity adsorbance; as long as outage disappears magnetic force; just can reclaim catalyst by the method for backwash, the catalyst of recovery can be got back in the hydrogenation operation and reuse.
The utility model all is suitable for the separation of the solid-liquid system that contains magnetisable material (as iron, nickel).
Description of drawings
What Figure of description 1 provided is the structural representation of the utility model embodiment.
