Description

The spiral type oil water separation device
Technical field
The utility model relates to a kind of tripping device of oily(waste)water, is specially adapted to the sharp separation of all kinds of lightweight oils and waste water, can prevent that oily(waste)water from polluting the rivers environment.
Background technology
Oily(waste)water enters the harm of water body: be mainly manifested in oils and cover the water surface, owing to having completely cut off air, the dissolved oxygen in water is reduced, cause the hydrocoles hypoxia death; BOD biochemical oxygen demand (BOD), COD chemical oxygen demand (COD) also overslaugh the photosynthesis of waterplant, make it to rot, cause that water quality fouls; Therefore, oily(waste)water must could discharge after dealing carefully with.
The contrast of several oil-contaminated water processing methods commonly used both at home and abroad at present:
1, utilize the gravitational separation processes such as oil trap, oil removal case, oil separation tank, efficiency is low, and volume is large;
2, separating centrifuge (or hydrocyclone) partition method, running cost is high, and facility investment is large;
3, coalescing separator filter core coarse separation method, filter core is short work-ing life, changes frequent;
4, air flotation pool dissolved air flotation method, need to take up an area larger area, builds air flotation pool, and investment is large, and the operational management cost is high;
5, chemical dosing partition method, running cost is high.
The utility model content
The purpose of this utility model is for the prior art above shortcomings, a kind of spiral type oil water separation device is provided, it has advantages of that separation efficiency is high, and can automatically detect the profit fluid level condition, realize Auto-drainage and oil extraction, also there are the characteristics that the life-span is long, use cost is low when cost of goods manifactured is cheap.
For achieving the above object, spiral type oil water separation device of the present utility model, comprise shell, the waterwater entrance pipe, the waste oil vent pipe, water shoot, it is characterized in that the end of waterwater entrance pipe with in shell longitudinally distribution pipe be connected, the lower end closed of distribution pipe, be provided with several apertures on the sidewall of distribution pipe, be provided with the several piece spiral plate in shell centered by distribution pipe, the material of the oleophyllie hydrophobic that the spiral plate surface adopts, the bottom of spiral plate all is connected with a base plate, be provided with the waste oil collecting bucket in shell above spiral plate, the bottom of waste oil collecting bucket is connected with the import of waste oil vent pipe, water shoot is located at the bottom of shell.
During use, oily(waste)water is pressed in distribution pipe through the waterwater entrance pipe, through aperture, be diverted in each spiral plate, and outwards flow twist around spiral plate, will allow like this inwall collision friction of more little oil droplet and spiral plate, and the material of the oleophyllie hydrophobic that the spiral plate surface adopts can be agglomerated into larger oil droplet to numerous little oil droplets.According to: the Stokes'theorem formula : the spherical object suffered resistance that moves in fluid, equal radius, speed, the viscosity of fluid and the product of 6 π of this spherical object, therefore little oil droplet collides in the spiral motion process, it is large that volume becomes gradually, thereby accelerated the ascent rate of waste oil, finally floated in the waste oil collecting bucket at top by outside waste oil vent pipe discharge machine;
As further improvement of the utility model, in the periphery of all spiral plates, also be provided with propeller cap; Can prevent the waste water diffusing, guarantee by helical flow;
As further improvement of the utility model, the several apertures on the distribution pipe sidewall are uniform on vertical and circumference; Can allow uniform being diverted in each spiral plate of oily(waste)water;
As further improvement of the utility model, be provided with the profit detection instrument above the waste oil collecting bucket, be equipped with motor-operated control valve on waste oil vent pipe and water shoot; The profit fluid level condition can be automatically detected, when the waste oil collecting in the waste oil collecting bucket of top is too much, the oil discharge outlet valve can be automatically opened outside waste oil eliminating machine; And can realize the automatic switchover of oil extraction and draining;
In sum, the utlity model has the advantage that separation efficiency is high, and can automatically detect the profit fluid level condition, realize Auto-drainage and oil extraction, also there are the characteristics that the life-span is long, use cost is low when cost of goods manifactured is cheap.
The accompanying drawing explanation
The structure iron that Fig. 1 is the utility model embodiment.
The stereographic map that Fig. 2 is Fig. 1 mesochite inner structure.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 1, shown in Fig. 2, this spiral type oil water separation device, comprise shell 1, waterwater entrance pipe 2, waste oil vent pipe 3, water shoot 4, the end of waterwater entrance pipe 2 with in shell longitudinally distribution pipe 5 be connected, the lower end closed of distribution pipe 5, be provided with several apertures 6 on the sidewall of distribution pipe 5, several apertures 6 are uniform on vertical and circumference, be provided with several piece spiral plate 7 in shell centered by distribution pipe 5, the material of the oleophyllie hydrophobic that spiral plate 7 surfaces adopt, as aluminium alloy or nm-class active calcium carbonate, the bottom of spiral plate 7 all is connected with a base plate 8, periphery at all spiral plates 7 also is provided with propeller cap 9, be provided with waste oil collecting bucket 10 in shell above spiral plate 7, the bottom of waste oil collecting bucket 10 is connected with the import of waste oil vent pipe 3, be provided with profit detection instrument 11 above waste oil collecting bucket 10, water shoot is located at the bottom of shell, be equipped with motor-operated control valve 12 or 13 on waste oil vent pipe 3 and water shoot 4.
During use, oily(waste)water is in waterwater entrance pipe 2 is pressed into distribution pipe 5, through aperture 6, evenly be diverted in each spiral plate 7, and outwards flow twist around spiral plate 7, will allow like this inwall collision friction of more little oil droplet and spiral plate 7, and the material of the oleophyllie hydrophobic that spiral plate 7 surfaces adopt can be agglomerated into larger oil droplet to numerous little oil droplets.According to: the Stokes'theorem formula : the spherical object suffered resistance that moves in fluid, equal radius, speed, the viscosity of fluid and the product of 6 π of this spherical object, therefore little oil droplet collides in the spiral motion process, it is large that volume becomes gradually, thereby accelerated the ascent rate of waste oil, finally float in the waste oil collecting bucket 10 at top by outside waste oil vent pipe 3 discharge machines, separation efficiency is high; Profit detection instrument 11 can detect the profit fluid level condition automatically, when the waste oil collecting in top waste oil collecting bucket 10 is too much, can automatically open motor-operated control valve 12 outside waste oil eliminating machine; The automatic switchover that two motor-operated control valves 12 or 13 can be realized oil extraction and draining, realize long-range unattended operation, has advantages of that when cost of goods manifactured is cheap the life-span is long, use cost is low.
