(oil-water separating and oil/fat recovering apparatus)
Oil-water separating and oil/fat recovering apparatus of the present invention is applicable to above-mentioned aqueous organic refuse treating system especially.
Below with reference to drawing, describe embodiments of the present invention in detail.
Fig. 1 is the outside drawing of oil-water separating and oil/fat recovering apparatus 1 of the present invention.Fig. 2 unloads embedded type top board 2, the in-built vertical view of the top component parts of sink 3 and coarse filter 4.Fig. 3 is the A-A profile of Fig. 2.Fig. 4 is the B-B profile of Fig. 2.Fig. 5 is the front view of auxiliary air separator.
Prepare before the liquid waste processing, by heater 6 heating, whole waste liquids that will store in oil-water separation tank 8 are preheated to 50-60 ℃.
Among Fig. 1, Fig. 3 and Fig. 4, waste liquid as shown by arrows, via waste liquid recipient 11, waste liquid conducting orifice 23, flows into the 1st groove 9 in the oil-water separation tank 8 via coarse filter 4, the sink 3 of superstructure.
In Fig. 2, the top of the 1st groove 9 is divided by vertical clapboard, forms the basket shape of upper opening, and the bottom of the vertical clapboard of the 1st groove 9 forms down with the state that reaches the 2nd groove side as the dividing plate inclined plane 14 of polyhedron structure.The area of the upper opening part of the 1st groove 9 is less with comparing of the 2nd groove 10.
The oil-water separation tank bottom land 20 of oil-water separation tank 8 has the gradient with the angled α of horizontal plane, β shown in Fig. 3,4, form to have the angle of slope γ that forms with the junction on the dividing plate inclined plane 14 of identical polyhedron structure, the gradient of δ.
The area of the upper opening of the 1st groove 9 part is compared less with the opening portion area of the 2nd groove 10, the upper opening part of volume ratio the 1st groove 9 of the bottom polyhedron baffle plate configuration part of the 1st groove 9 big the following describes the reason of formation.
The first, separate showy grease under the situation of given volume from a waste liquid that flows into, on the big oil-water separation tank liquid level of opening portion area, the oil layer volume spreads thinly, and the waste liquid principal component water that belt type oil skimmer draws is more than grease.For fear of this phenomenon, it is floated having on the 1st tank liquor face of little aperture area, increase the oil layer volume that forms.The efficient that this result makes belt type oil skimmer 5 draw grease improves.
The second, a certain amount of low-temperature primary waste liquid is injected in the waste liquid that is preheated storage of the 1st groove 9, then because the low-temperature primary waste liquid is lower than the liquid temperature of a waste liquid that is preheated storage, density is big, sedimentation in the 1st groove.The low-temperature primary waste liquid of sedimentation is in the diffusion inside on the dividing plate inclined plane 14 of the polyhedron of the 1st groove 9 structure, is preheated a waste liquid of storage from jumbo the 2nd groove that surrounds the 1st groove 9, and the dividing plate inclined plane by the polyhedron structure absorbs the heat that conduction is accumulated.
When carrying out conduction of heat, the area that low temperature side contacts with high temperature side is big more, and its speed is fast more.In order to obtain this effect, increase the surface area of the lower partition of separating, form polyhedron inclined plane structure, set best angle of slope γ, δ.
The 3rd, the low-temperature primary waste liquid absorbs heat from a waste liquid that is preheated storage on every side, and one reaches thermal equilibrium state, and the drip of grease group of then containing is because its specific heat ratio water is little, and it is faster than water to heat up, volume expansion.Its result, the drip of grease population density reduces, and has promoted to separate to float.This separates drip of grease group's collision on the dividing plate inclined plane 14 of polyhedron structure of floating, and owing to surface tension is assembled, grain drips grows up, and increases buoyancy.The dividing plate inclined plane 14 of polyhedron structure has the effect that promotes that this oil droplet is grown up, floated.
Separate the dividing plate material of oil-water separation tank 8 if form the good result of acquisition aspect processability, corrosion resistance, heat conductivity with the stainless steel of steel class.The border of each face on the dividing plate inclined plane 14 of formation polyhedron structure does not have concavo-convex and because the surface of each face is bright finished, effect is better.
By the low-temperature primary waste liquid that flows into, illustrate that the grease that contains separates the process of floating.
Flow into oil-water separation tank the 1st groove 9 with the liquid stream of label (1) expression or a waste liquid of capacity.When the low-temperature primary waste liquid flowed into waste liquid of the storage that is preheated to 50-60 ℃, the waste liquid that low temperature flows into was bigger than the density of a waste liquid of the storage that is preheated, the sedimentation in oil-water separation tank the 1st groove 9 of a waste liquid of inflow.
In the process of the dividing plate inclined plane regional subsidence of the polyhedron structure of low-temperature primary waste liquid in oil-water separation tank the 1st groove 9,, carry out conduction of heat from the waste liquid heat absorption that the whole oil-water separation tanks that are preheated store.In order to promote this conduction, be provided with the zone, inclined plane 14 of polyhedron structure so that the 2nd groove 10 surround the 1st groove 9 around and the contact area of the 2nd groove become big.
Because this influence, at the low-temperature primary waste liquid of the dividing plate inclined plane regional subsidence of the polyhedron of the 1st groove 9 structure by the aforementioned barriers inclined plane from being preheated a waste liquid heat absorption of storage.When reaching the conduction of heat equilibrium state, the drip of grease group of containing is because the specific heat ratio water of grease is little, and grain drips than water heat absorption earlier, its volume expansion, and density reduces.As a result, promoting a waste liquid to separate floats.
From the mobile label (2) towards a waste liquid of outlet pass 15, the drip of grease group that the volume expansion by heat absorption, density reduce is floated according to difference in specific gravity, collision on the dividing plate inclined plane 14 with the polyhedron structure that forms on the specular surface of gradient.The drip of grease group of collision grows up to big oil droplet owing to showing that tension force is assembled, and its buoyancy increases.Because the dividing plate rake surface of polyhedron structure is a mirror status, the oil droplet of growing up is attached to the surface of the dividing plate rake of polyhedron structure, along the aforementioned barriers surface, floats towards the liquid level of the 1st groove 9.This process is carried out continuously, and oil droplet floats from a waste liquid separates.
So, the dividing plate inclined plane 14 of polyhedron structure is because the prolongation of the holdup time of low-temperature primary waste liquid and at a waste liquid that low temperature flows into and be preheated between the waste liquid of storage and need to carry out fast conduction of heat, employing has by separate the polyhedron baffle plate configuration on the inclined plane of the big surface area that obtains with vertical plate, so that can carry out rapidly from the conduction of heat of the 2nd groove 10, and, the drip of grease group that waste liquid contains under the relation of specific heat than water heat absorption earlier, because its volume expansion and density reduces, float along with separating, the drip of grease group's of floating aggregation obtains the effect that the promotion oil droplet is grown up.In this process, the grease that the major part from a waste liquid is contained separates and floats to the liquid level of the 1st groove 9.
It more than is the effect that obtains by the dividing plate inclined plane 14 that polyhedron is constructed.
The grease that major part from a waste liquid is contained separates the secondary waste liquid that floats to the liquid level of the 1st groove 9 via outlet pass 15, flow into capacious oil-water separation tank the 2nd groove 10, become the stable liquid stream of expansion bigger than the width of outlet pass 15 on width, the drip of grease group of the remnants that contain is being floated to the liquid level of the 2nd groove 10 according to difference in specific gravity, on liquid level, assemble and grow up, form oil layer.
Float oil layer to the liquid level of the 2nd groove 10 in order to keep mobile, be drawn into together by the subband formula oil skimmer 13 that can adjust arbitrarily the service cycle that on the 2nd groove 10, is provided with and secondary waste liquid and return in the grease recipient 12.This returns grease recipient 12 and is connected with the waste liquid recipient, and grease that it draws and the low-temperature primary waste liquid that flows into again are injected in oil-water separation tank the 1st groove 9 together.
The grease that draws from the 2nd groove 10 is because oil droplet is grown greatly, even and the low-temperature primary waste liquid inject the 1st groove 9 together, also be absorbed on the irrelevant original showy oil layer that flows with above-mentioned low-temperature primary waste liquid, increase the volume of this original oil layer.As a result, master tape formula oil skimmer 5 also is stored in grease in the recycling can 7 when the efficient of grease is drawn in raising.
The grease that reclaims has the high-purity of effectively utilizing as the secondary resource of making fertilizer, feed.
Setting up on the liquid level direction under the effect of the auxiliary air separator inflow entrance 17 of auxiliary air separator 16 up of the 2nd groove 10, this auxiliary air separator promotes the water-oil separating in oil-water separation tank the 2nd groove 10, even the secondary waste liquid flows into from auxiliary air separator inflow entrance 17, the drip of grease that contains flows against the secondary waste liquid, towards the liquid level of the 2nd groove 10 and float, and do not hinder showy.
The effect of the auxiliary air separator 16 that explanation is provided with in oil-water separation tank the 2nd groove 10.
