Background technology
Mechanical separation generally uses gravitational field and centrifugal force field that the alternate mixed material that there is density variation is easily separated operation, in the industrial production extensive use significant. When fluid circles, form the inertial centrifugal field of force, for non-homogeneous mixture, owing to the density of continuous phase or dispersion phase is different, cause that the gravity of fluid particle and centrifugal force are all different. The heavy phase that density is big is subject to centrifugal inertial force effect to side shifting outside rotating fluid, moves down under gravity meanwhile; And little light phase of density is moved to rotating fluid center, and move up under buoyancy differential pressure effect.
Segregation apparatus based on gravitational field has subsider, dust-settling compartment, thickener, clasfficiator and swash plate segregation apparatus etc., wherein swash plate segregation apparatus utilizes gravitational field and mechanism of shallow-layer sedimentation to accelerate the separation of non-homogeneous mixture, the more common sedimentation techniques of separation efficiency are greatly improved, the occasion that applicable production site is less. Segregation apparatus based on centrifugal force field has cyclone separator, cyclone hydraulic separators, solid bowl centrifuge, disk centrifuge, tubular-bowl centrifuge etc., centrifugal force is used to accelerate separation process, the physical dimension of existing centrifugal force field separation equipment is less, early investment is high, power consumption is big, and disposal ability is limited.
Develop a kind of wall formed under spiral roll bending effect guiding eddy flow flowing, utilize gravitational settling to combine with centrifugal sedimentation and realize weight and be separated. Spiral roll bending not only counteracts the Involving velocity of mixed material entrance, and decreases the repeat separation processes remixing and separating, has good practical significance for improving and strengthening non-homogeneous mixture lock out operation.
Summary of the invention
It is an object of the invention to provide a kind of spiral roll bending cyclone separation device, apparatus of the present invention are on the basis of gravitational field, use the centrifugal force that the guide functions in helical coil wooden partition face is formed and the separation accelerating non-homogeneous mixture along the subsiding movement between the spiral wall of centrifugal force direction.Realize without moving link, the purpose improving disposal ability and separation efficiency.
It is an object of the invention to be achieved through the following technical solutions:
A kind of spiral roll bending cyclone separation device, described segregation apparatus includes separating tank or tank body, mixed material entrance, spiral roll bending, downflow weir, light phase export, heavy out and adnexa; Tank body includes cylinder and low head; Spiral roll bending is monovolume plate or is distributed in mixed material entrance both sides, forms symmetric plate bending; Spiral roll bending is the side that monovolume plate mixed material entrance (2) is arranged in separating tank or tank body, forms phase cut type entrance or arranges unidirectional baffle plate, and spiral roll bending direction of rotation is identical with fluid; Or spiral roll bending is symmetric double roll bending.
Described a kind of spiral roll bending cyclone separation device, the entrance of spiral roll bending and the tangent or angled layout of outer layer roll bending; Distance between spiral roll bending adjacent layer is equal.
Described a kind of spiral roll bending cyclone separation device, the cross section of separating tank or tank body is closed curve.
Advantages of the present invention and effect be:
1. the separation efficiency of spiral roll bending cyclone separation device of the present invention is high. The guide functions in helical coil wooden partition face makes fluid form eddy flow, and continuous phase or the density contrast of dispersion phase in non-homogeneous mixture cause that the centrifugal force of fluid particle is different. Heavy phase moves to wall under centrifugal action, owing to helical coil wooden partition interplanar distance is less, substantially reduces the heavy phase time to solid wall surface, accelerates the separation of non-homogeneous mixture in wall normal direction. The arrangement increases mixed effect, even if also can efficiently separate out trickle granule without flocculant;
2. spiral roll bending cyclone separation device of the present invention there is also eddy flow along with the lower and upper fluid along space above under spiral roll bending, improves the further separation to non-homogeneous mixture;
3. the spiral roll bending in spiral roll bending cyclone separation device of the present invention at common separation groove or separates installation in tank body, can improve the separation efficiency of existing equipment;
4. spiral roll bending cyclone separation device production capacity of the present invention is high, and simple and compact for structure, processing and manufacturing is simple, and floor space is few, is highly suitable for the occasion that production site is less;
5. spiral roll bending cyclone separation device of the present invention is for different application scenarios and operating condition, and roll bending spacing can be adjusted along with the condition of production, flexible configuration.
