Background technology
Carrier separator (also claiming triphase separator) is a vitals of guaranteeing the efficient operation of fluidized-bed, and its performance directly influences the fluidized-bed reactor treatment effect.Chinese patent 03123800.9 discloses a kind of biological fluidized-bed reactor labyrinth type carrier separator, and its structure is to be made of three layers of interlaced trilateral reflection cone, in actual manufacturing processed, is to be welded to form by artificial stacking by the metal triangular bar.This structure carrier separator, though have separating effect preferably, be that existing carrier isolating is improved greatly, but in actual application, still find to exist some deficiency, for example separator can only adopt metal construction to make, and for reaching the high efficiency separation effect, between every layer of trilateral reflection cone and the distance less (only 10-20mm) between reflection cone layer and the layer, field assembly, welding are relatively more difficult like this, difficulty of construction is big, be difficult to reach design requirements, thereby cause the separator separating effect to reduce.Secondly, plain metal carbon steel triangular strip, corrosion-resistant, though handle through surface anticorrosion, but owing to the tiny slit reason in welding back, be difficult to repair corrosion protection coating again, and coating also needs regular anticorrosion maintenance at welding assembly, because this separator is arranged on the fluidized-bed reactor middle and upper part, and fixing weldering fast knot structure, safeguard anticorrosion very inconveniently, not only can reduce work-ing life, and the corrosion cause the surface crude, also can influence the smooth and easy landing of carrier.Besides, this separator adopts the isosceles right triangle reflection cone, the reflection cone surface slope is little, also be unfavorable for the landing of carrier of separating, add that the metal body surface corrosion causes the surface crude, easily causes bio-carrier to pile up on the reflection cone inclined-plane, so that stop up separator, because separator is mounted in the equipment middle part, need manually pierce pine weldering field-strip once break down, very inconvenient.If adopt stainless steel trilateral reflection cone, can cause the cost increase bigger again.A deficiency is again, because this separator trilateral reflection cone is a right angled isosceles triangle, composite factor such as the landing surface slope is less, surface corrosion is crude and the welding production error is bigger, it is not ideal enough that effect is held back in the carrier separation, cause the carrier turnover rate higher, about the practical engineering application middle age, the carrier turnover rate was up to 15%, thereby cause running cost to increase, and treatment effect stability is not ideal enough.Also have in actual engineering for reducing cost, trilateral reflection cone or adopt ready-made angle steel or the steel plate bending, reality opening-like attitude in bottom also can influence separating effect.
The utility model content
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, and a kind of advantage that not only can keep aforementioned separator is provided, and can overcome its above-mentioned all insufficient fluidized-bed carrier separator.
The utility model purpose realizes, the main improvement is by changing interlayer trilateral reflection cone mode of connection, adopt customization slot plate fixed triangle shape reflection cone, and levels is connected and fixed, promptly adopt the triangle reflection cone retaining plate of band slot contract mouth at the reflection cone interlayer, make triangle reflection cone positioning and fixing by contract mouth on the slot plate, need not adopt welding fixing like this, not only can adapt to and adopt nonmetal for example plastic production triangle reflection cone, and can make module, only need on-the-spot placement, fixed mould, thereby realize the foregoing invention purpose.Specifically, utility model fluidized-bed carrier separator, by the synthetic lamina of some trilateral reflection cone interleaved set, it is characterized in that each trilateral reflection cone for to make the triangle body that three bandings close by non-metallic material, the triangle body interlayer by upper and lower surface respectively be connected the combination of back up pad location with triangled tip cooperates slot contract mouth at the bottom of the triangle.
Utility model is owing to adopt the groups of slots assembling structure, and the trilateral reflection cone can adopt various non-metallic material to make, and is excellent with the plastics that are fit to pultrusion especially wherein, has very high production efficiency, and good corrosion prevention performance and surperficial landing performance.
For improving the globality of combination trap, it can be brushing glue bonding in the slot mouth, also can be provided with and connect side plate or bar up and down in the combination trap both sides, can also be that the trilateral reflection cone inserts pointed cone portion and is provided with the anticreep side wing that intersects (for example parallel or almost parallel base) with the inclined-plane, and accept groove what the setting of triangled tip slot cooperated with it.
In addition, for more helping the smooth and easy landing of carrier of separating, avoid separator to stop up a kind of equilateral triangle or acute angle isosceles triangular structure of more preferably adopting of trilateral reflection cone.
Utility model fluidized-bed carrier separator, because adopting the web plate of band slot contract mouth to make the levels trilateral connects, thereby overcome the deficiency of existing trilateral reflection cone welding combination trap, not only can adopt for example making such as plastics of non-metallic material fully, and can adopt the pultrusion of high efficiency, and do not need to do in addition rotproofing and maintenance.Secondly, this structure separator combination is convenient, can be made into modular construction in advance, realize stdn, producing in serial form, need put fixing getting final product for on-the-spot, omitted the trouble of metallic reflection awl site welding, made that separator is installed, dismounting, maintenance, change very conveniently, installed, maintenance all can be undertaken by the fluidized-bed access opening.Besides, adopt the trilateral reflection cone of a pultrusion of plastics, not only sealed up the bottom surface, good separating effect, and the reflection cone inclined-plane is smooth, more helps the smooth and easy landing of carrier of separating, carrier is difficult for accumulating, and because the surface can be not crude because of the corrosion generation, stability is kept; And adopting equilateral triangle or acute angle isosceles triangle reflection cone, surface slope is big, also more helps the downslide of separating bio carrier, not only can not cause the obstruction of separator, but also has reduced the turnover rate of carrier; And precast construction, improve separator greatly and made precision, can guarantee to design separation efficiency.Test shows that this separator separates year turnover rate to bio-carrier and can reduce to 5% from present 15%, and carrier is held back effect and improved greatly, not only helps reducing replenishing of carrier filler, reduces running cost, and the treatment effect good stability.
