Description
Technical field
the invention belongs to field of mechanical technique, particularly relate to a kind of Design and manufacture of continuous precipitator.
technical background
at present in sugar industry, use traditional continuous precipitator, be Dorr formula settling vessel.The operation principle of this kind of settling vessel is sugarcane juice is all enter from the lower position of body central authorities, is distributed on the whole cross section of body, lentamente to rising, releases from the ring exit pipe of top; The rate of climb of sugarcane juice, is generally 0.7 ~ 1.3cm/min in Dorr settling vessel, and the suspended particulates in sugarcane juice are sedimentation downwards then.In this sedimentation workspace, sugarcane juice is to upper reaches to sinking for particulate, and both direction of motion is just in time contrary, and mutual intersection, pushes up punching mutually, if enter juice or go out juice which unstable time, all can cause at " the anti-end ".The direct interference of the sugarcane juice that this motor pattern can make the sedimentation of particulate upwards be flowed, job insecurity, microparticles settle is slow, and is difficult to reach complete.The pattern of this reverse flow is the fundamental cause at continuous precipitator job insecurity and the easy anti-end.In this settling vessel, if the sinking speed of particulate is less than the speed that juice upwards flows, particulate is just taken away by sugarcane juice, makes juice feculence clearly.Only when the sinking speed of particulate is greater than the speed that juice upwards flows, particulate can relatively sedimentation downwards.
in sulfitation sugar mill, sugarcane juice adds after ash and post bake through stove drying, and wherein sedimentary free-falling velocity is generally within the scope of 0.8 ~ 2.0cm/min, has sizable difference depending on the quality of sugarcane juice and the effect of clarifying treatment.Some juice poor especially may be low to moderate 0.5cm/min.Like this, enter juice flow large and the sugarcane juice rate of climb is fast time, to be just easy to sediment band, to rising, cause juice muddiness clearly; Also this problem is easily there is when juice quality is bad or clarifying treatment is bad.Even if sedimentary sinking speed is greater than the speed at juice upper reaches clearly, sedimentary actual sinking speed is also the difference (microparticles settle speed subtracts Flow Velocity on juice) of these two speed, more much lower than the real sinking speed of particulate itself, so just substantially prolongs sediment be deposited to bottom needed for time.Therefore, in traditional settling vessel, the upper Flow Velocity of sugarcane juice must be lower than the sinking speed of particulate quite a lot of, and particulate just can settle down, and obtains clear liquid.Like this, settling vessel must have very large sectional area, and to lower the speed that sugarcane juice upwards flows, it also will have larger height, and sugarcane juice just can be made to be evenly distributed on cross section.Therefore, the volume of traditional settling vessel and floor space all very large.In sugarcane juice, the composition of suspended particles and the size of proportion and particle are not changeless, and their " free-falling velocity " neither be homogeneous.The particle larger than great and size is heavy soon, little heavy slowly of the little and size of proportion, proportion be less than liquid also to floating.When sugarcane juice upwards flows with same speed, in juice, massive particle can sink, but light and little particle is easily taken away by juice, causes juice clearly muddy.On the other hand, in particulate sinking watching, unsteady for cohesion suspension upset can be stirred loose by the sugarcane juice to upper reaches, therefrom isolates more carefully and lighter particulate, with sugarcane juice to upper reaches.Particularly add the thicker of flocculant formation but acarpous flocculate, more easily broken up by the sugarcane juice of reverse flow.Such as, although the flocculate originally formed has higher sinking speed, 6 ~ 8cm/min because size is comparatively large, after they are broken up by reverse liquid stream, its actual sinking speed just significantly reduces, and makes to add the effect that flocculant produces and greatly weakens.In addition, in the gross area of settling vessel, the upper Flow Velocity of sugarcane juice can not completely evenly, and on the position of close import and outlet, federation is higher; These regions more easily occur the phenomenon on particulate band when sugarcane juice rises.
traditional continuous precipitator is easily by sediment band supernatant juice district, cause the anti-end, and it is responsive especially to the change entering juice condition, when the concentration or variations in temperature that enter juice make the proportion change of sugarcane juice, in device just there is convection current in the sugarcane juice of different piece, make sediment convection current thereupon, clear juice with regard to feculence, the therefore settling vessel easily anti-end because of change of external conditions.
