Description

Technical Field

[0001] This utility model relates to the field of water purification equipment technology, and in particular to an improved vortex grid flocculation reaction device. Background Technology

[0002] In drinking water treatment processes, conventional processes, such as flocculation-sedimentation-filtration, dominate. The flocculation stage refers to the aggregation of colloidal particles and tiny suspended solids in water under the action of coagulants. Common flocculation methods include perforated cyclone flocculation, baffle flocculation, folded plate flocculation, and grid (strip) flocculation. In rural water supply scenarios, due to the smaller scale of water supply and lower investment costs, circular integrated water purification equipment is widely used. However, existing flocculation reaction designs are difficult to fully adapt to small-scale circular integrated water purification equipment. Currently, the flocculation reaction structure of circular integrated water purification equipment still has many problems. Its design standards are inconsistent, and the structure is often too simplistic. For example, many use simple flocculation ball forms, and some equipment lacks a corresponding flocculation reaction structure altogether, failing to meet existing design specifications and standards. This results in poor flocculation effects, which in turn affect subsequent sedimentation and filtration stages, ultimately making it difficult to guarantee the quality of rural drinking water.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] It should be noted that the terms "horizontal" and "vertical" in this utility model are used to describe approximate positional relationships, and not strictly "horizontal plane" or "vertical plane".

[0022] like Figure 1-5 As shown, an improved swirl grid flocculation reaction device according to a preferred embodiment includes: an inner cylinder 1, an outer cylinder 2, an inlet pipe 3, and an outlet pipe 4. The inner cylinder 1 is disposed inside the outer cylinder 2. One end of the inlet pipe 3 passes through the outer cylinder 2 and is connected to the inner cylinder 1. One end of the outlet pipe 4 extends into the outer cylinder 2. The inner cylinder 1 has a multi-layer swirl reaction zone 11 and a bottom water distribution zone 12 arranged sequentially from top to bottom. The multi-layer swirl reaction zone 11 is connected to the bottom water distribution zone 12. Several vertical grid plates are disposed in the multi-layer swirl reaction zone 11.

[0023] Furthermore, as a preferred embodiment, a water collection tank 21 is provided inside the outer cylinder 2, and one end of the water outlet pipe 4 extends into the outer cylinder 2 and is connected to the water collection tank 21.

[0024] Furthermore, as a preferred embodiment, the outer cylinder 2 has an inclined tube sedimentation zone 22, a laminar flow flocculation zone 23, and a sludge discharge zone 24 arranged sequentially from top to bottom. The inclined tube sedimentation zone 22 is located between the inner cylinder 1 and the water collection tank 21. The laminar flow flocculation zone 23 is located between the outer wall of the inner cylinder 1 and the inner wall of the outer cylinder 2. The laminar flow flocculation zone 23 can keep the water flow in a laminar state, which is more conducive to the formation of flocs. The sludge discharge zone 24 is located at the lower end of the inner cylinder 1 and is used to collect the settled flocs.

[0025] Furthermore, as a preferred embodiment, a horn-shaped collection hood 13 is provided at the upper end of the inner cylinder 1. The horn-shaped collection hood 13 is positioned directly opposite the inclined tube sedimentation zone 22, and the horn-shaped collection hood 13 is connected to the sludge discharge zone 24 through a sewage discharge pipe.

[0026] Furthermore, as a preferred embodiment, the multi-layer swirl reaction zone 11 has a front flocculation zone 111 and a middle flocculation zone 112 arranged sequentially from top to bottom.

[0027] Furthermore, in a preferred embodiment, the vertical grid plate includes: a first grid plate 5 and a second grid plate 6. A plurality of first grid plates 5 are disposed within the front flocculation zone 111, and a plurality of second grid plates 6 are disposed within the middle flocculation zone 112. The mesh outline of the second grid plate 6 is larger than that of the first grid plate 5. Furthermore, when water flows through the mesh openings of the first grid plate 5 and the second grid plate 6, turbulence and eddies are induced, thereby forming numerous tiny vortices and disturbance zones. This causes the particles in the water to generate more complex relative motions. This motion mode not only increases the collision frequency between particles but also creates more opportunities for aggregation after collisions, thus facilitating floc formation.

[0028] Furthermore, as a preferred embodiment, a plurality of through holes are provided on the inner wall of the bottom water distribution zone 12, and the through holes connect the laminar flow flocculation zone 23 and the bottom water distribution zone 12.

[0029] Furthermore, in a preferred embodiment, both the front flocculation zone 111 and the middle flocculation zone 112 have several reaction zones, each separated by a partition 14. Each partition 14 has a connecting hole 15, and the connecting holes 15 on adjacent partitions 14 are staggered. Further, the several reaction zones are evenly distributed vertically, and one end of the inlet pipe 3 is connected to the uppermost reaction zone. Water can enter the uppermost reaction zone of the front flocculation zone 111 from the inlet pipe 3, and then flow down to the next reaction zone.

[0030] Furthermore, as a preferred embodiment, each reaction zone in the front flocculation zone 111 is preferably provided with four first grid plates 5, which are evenly distributed along the circumference of the inner cylinder 1. Similarly, each reaction zone in the middle flocculation zone 112 is preferably provided with four second grid plates 6, which are also evenly distributed along the circumference of the inner cylinder 1. Furthermore, water flow can rotate and flow between the first grid plates 5 or second grid plates 6 in the same reaction zone, and enter the next reaction zone through the connecting hole 15.

[0031] The working principle of this utility model is as follows: During use, sewage enters the inner cylinder 1 through the inlet pipe 3. After flocculation reaction in the front flocculation zone 111 and the middle flocculation zone 112, the sewage enters the bottom water distribution zone 12 and then flows into the laminar flow flocculation zone 23 in the outer cylinder 2 through the through hole on the bottom water distribution zone 12. The sewage can undergo flocculation reaction in the laminar flow flocculation zone 23. As the water level in the outer cylinder 2 rises, the sewage that has completed the flocculation reaction can enter the inclined tube sedimentation zone 22 for floc sedimentation. The settled flocs can fall from the inclined tube sedimentation zone 22 into the trumpet collection hood 13 and be discharged into the sludge discharge zone 24 through the trumpet collection hood 13 and the sewage discharge pipe. As the water level in the outer cylinder 2 rises, the clarified water that has completed the floc sedimentation can enter the water collection tank 21 and be discharged into the external filtration equipment through the water outlet pipe 4.

[0032] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
