Description
Technical field
The present invention relates to the technical field of oily water separating equipment, particularly a kind of air supporting and swirling flow unit process combine the liquid-liquid air supporting cyclone separator of formation.
Background technology
At present; Eddy flow and air supporting all are the effective element method of oily water separation, and pneumatically supported element method was formed oil-water separation system after the usually oil water sepn adopted first eddy flow, but the usually oil water separating system exists number of devices many; Floor space is big, the not high shortcoming of oily water separation efficient.
Summary of the invention
The objective of the invention is provides a kind of and not only can improve oily water separation efficient in order to overcome the deficiency of prior art, and the cyclone air-flotation water-and-oil separator that volume is little, investment cost is low.
The objective of the invention is to realize like this: the cyclone air-flotation water-and-oil separator, comprise the cylindrical tank of vertical setting, the upper end inwall of tank body vertically is provided with collection tank, and the lower end of collection tank connects oil outlet pipe; Said jar of intravital central vertical is to reaction tube is set; The top of reaction tube is cylindrical, and the bottom of reaction tube is a taper type, vertically places swirler-in the upper end of reaction tube; The lower end of swirler-connects first pipeline, and the outlet end of first pipeline passes the bottom that reaction tube and tank body are connected reaction tube; Said tank body is provided with liquid-inlet pipe and inlet pipe outward; Connect aerator on the inlet pipe; The outlet end of liquid-inlet pipe is connected same line mixer with the outlet side of inlet pipe, and the other end of line mixer connects second pipeline, and second pipeline passes on the tangential that tank body is connected the outer swirler-of reaction tube; Place injector on the tangential of said tank body, the input terminus of injector connects the circulation delivery side of pump, the tank base that the input terminus ligation tube of recycle pump is outer, and the outer tank base of reaction tube also connects rising pipe.
Oily(waste)water gets into from water-in, and through the oil droplet of swirler-high speed rotating removal larger particles, water goes out from the swirler-bottom; And from reaction tube bottom get into and with reaction tube in the medicament hybrid reaction; Mix the back and go out, get into reaction tube and tank body annular space and down move, in this descending process from reaction tube top; Because injector outlet current drive the water rotation along tank body hoop high-velocity jet; And contain a large amount of micro bubbles in the injector water outlet, during rotation because the GWR method of double differences makes micro bubble move simultaneously upwards buoyance lift to the annular space center, micro bubble in moving process with annular sewage in fine oil droplet combines and carries oil droplet and move arrival reaction tube outer wall to center of gravity; Countless such oil droplets buoyance lift upwards after the central tube outer wall accumulates big oil droplet, thus reach the purpose of removing oil in the water.
The present invention is the vertical vessel of a job under near normal temperature, normal pressure, strengthens oily settlement separately through induction flotation and eddy flow, and the injector through the container middle and upper part provides eddy flow power and injects bubble; Owing to rotating the centrifugal action that produces; The water that density is bigger will move to tank skin, and lighter compositions such as oil droplet and bubble are pressed towards in the middle of the jar, arrive the internal reaction barrel; Oil droplet and bubble combination density rise less than ambient water; Rising through bubble is carried out flotation to oil droplet, and the oil droplet less by bubble absorption condenses gradually, in conjunction with producing bigger oil droplet; Final in gas-floating chamber the upper strata of liquid form the successive layers of oil or milk sap, produce the oil gas stores and successively flow into oil trap and be eliminated through draw-off pipe.The invention has the beneficial effects as follows: not only can improve oily water separation efficient; And the residence time is short, volume is little, in light weight, floor space is few; Investment cost is low; Easy and simple to handle, advantage such as use flexibly, long service life, maintenance cost are few, be desirable efficient oily water separating equipment in the oily water treatment.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 be among Fig. 1 A-A to view.
Fig. 3 is an another kind of structural representation of the present invention.
Among the figure, 1 collection tank, 2 swirler-s, 3 reaction tubes, 4 tank bodies, 5 recycle pumps, 6 pressure regulator valves; 7 injectors, 8 air dissolved pumps, 9 line mixers, 10 oil outlet pipes, 11 rising pipes, 12 first pipelines; 13 inlet pipe, 14 liquid-inlet pipes, 15 second pipelines, 16 pneumatic tubes, 17 sealing covers, 18 inlet mouths.
Embodiment
Like Fig. 1, shown in 2, be the cyclone air-flotation water-and-oil separator, comprise the cylindrical tank 4 of vertical setting, the upper end of tank body 4 connects sealing cover 17, connects pneumatic tube 16 on the sealing cover 17.The upper end inwall of tank body 4 vertically is provided with collection tank 1, and the lower end of collection tank 1 connects oil outlet pipe 10.Central vertical in the tank body 4 is to reaction tube 3 is set; The top of reaction tube 3 is cylindrical; The bottom of reaction tube 3 is a taper type, vertically places swirler-2 in the upper end of reaction tube 3, and the lower end of swirler-2 connects first pipeline 12; On first pipeline 12 pressure regulator valve 6 or regulator are set, the outlet end of first pipeline 12 passes the bottom that reaction tube 3 and tank body 4 are connected reaction tube 3.Tank body 4 outer liquid-inlet pipe 14 and the inlet pipe 13 of being provided with; Connect air dissolved pump 8 or dissolving or air compressor machine or injector on the inlet pipe 13; The outlet side of the outlet end of liquid-inlet pipe 14 and inlet pipe 13 is connected same line mixer 9; The other end of line mixer 9 connects second pipeline, 15, the second pipelines 15 and passes on the tangential that tank body 4 is connected the outer swirler-2 of reaction tube 3.Place 7, four injectors 7 of four injectors on the tangential of tank body 4 and be distributed on the circumference of tank body 4, the inlet mouth 18 that 18, four injectors 7 of an inlet mouth are set respectively on each injector 7 is through same pneumatic tube 16 of pipe connection.The input terminus of four injectors 7 connects the output terminal of same recycle pump 5, tank body 4 bottoms outside the input terminus ligation tube 3 of recycle pump 5, and reaction tube 3 outer tank body 4 bottoms also connect rising pipe 11.
As shown in Figure 3, injector 7 is two, and two injectors 7 are distributed on the tangential of tank body 4.
Oily(waste)water with certain pressure at a high speed gets into swirler-2 inner chambers from tangential inlet with dissolved air water after line mixer 9 mixes, form eddy flow field, because there is density difference in oil-gas-water; Under centrifugal action, water is thrown toward wall, and oil-gas will be compelled to migrate to the center low pressure area; Gas density density in three of oil-gas-waters is minimum, and micro bubble is the fastest to the center migration velocity, in this process; Micro bubble will carry oil droplet, forms oil-gas complex body, thereby quickens the migration velocity of oil droplet; Simultaneously also with fine particles; Be difficult to isolating oil droplet and bring core place (reaction tube 3 outer walls) into, realize air supporting choosing and rotational flow separation synergistic effect, the medicament reaction gets into air flotation zone (annular space between reaction tube 3 and the tank body 4) then in the water entering reaction tube 3 after swirler-2 is handled; Gas-liquid mixture by injector 7 ejections provides power; Make the interior liquid of air flotation zone make circumferential motion, micro bubble to the migration of jar center, carries simultaneously and remains oil droplet in the entering air flotation zone water to a center migration arrival jar central reaction drum outer wall under centrifugal action in injector 7 water outlets; And be gathered into big oil-gas complex body buoyance lift that makes progress at the reaction tube outer wall, further separate thereby accomplish profit.
