Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a horizontal reaction plate of a flocculation reaction tank. Background Art

[0002] The particle sizes of suspended substances and colloidal substances in natural water are very small. To remove these substances, the means of coagulation is usually used, that is, an appropriate coagulant is added to the raw water. After sufficient mixing, the colloidal stability is destroyed (de-stabilized) and adsorbed with the polymer after hydrolysis of the coagulant, so that the particles have flocculation performance. The purpose of the flocculation reaction tank is to create appropriate hydraulic conditions for the particles with flocculation performance to aggregate in mutual contact to form larger flocs (floccules). Therefore, whether the design of the flocculation reaction tank is appropriate is related to the flocculation effect, and the flocculation effect directly affects the sedimentation effect of subsequent treatment.

[0003] To improve the flocculation effect, the common forms of flocculation reaction tanks used in many rural waterworks at present are: partition flocculation tanks, flat-folded plate flocculation tanks, corrugated plate flocculation tanks, grid (or grid bar) flocculation tanks. Among them, the grid plates of the grid (or grid bar) flocculation tanks are installed horizontally, and most of the grid plates are square grids, and there are also circular grids. The installation of the grid plates of the grid (or grid bar) flocculation tanks is difficult and the maintenance is inconvenient. Moreover, after the flocculation reaction tank operates for a period of time, flocs will accumulate on these grid bars, affecting the sedimentation effect of subsequent treatment and the water quality of the effluent. The partition flocculation tank, the flat-folded plate flocculation tank, and the corrugated plate flocculation tank are all installed vertically; however, the partition intervals are large and need to be fixed by brackets, and the installation is troublesome.

[0004] Therefore, it is necessary to provide a new solution to solve the above technical problems. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a horizontal reaction plate of a flocculation reaction tank, so as to effectively solve the problems put forward in the background art.

[0006] To achieve the above purpose, the utility model adopts the following technical solution: a horizontal reaction plate of a flocculation reaction tank, including reaction plate I, reaction plate II, and reaction plate III.

[0007] Preferably, the structure of the reaction plate I is that there are multiple rows of hollow conical bosses protruding on a flat plate. There is an opening for the reaction plate I in the middle of the top surface of each boss. There is a section of interval between each boss. Bolt holes are arranged in the interval area. The bosses of every two reaction plate Is are tightly attached to each other outward, and bolts are installed in the bolt holes to assemble the two reaction plate Is into one body.

[0008] Preferably, the size of the reaction plate I is 1000mmX1000mm.

[0009] Preferably, the structure of the reaction plate II is a flat plate with multiple rows of hollow conical bosses protruding. There is an opening on the middle of the top surface of each boss. The lower ends of all bosses are in close contact. There are bolt holes on the side of the flat plate. Every two reaction plate II bosses are in close contact with each other outward, and bolts are installed in the bolt holes to assemble the two reaction plate IIs into one body.

[0010] Preferably, the size of the reaction plate II is 1000mmX1000mm.

[0011] Preferably, the structure of the reaction plate III is the same as that of the reaction plate I, and the assembly method is also the same. The size of the reaction plate III is 1000mmX3000mm.

[0012] The beneficial effects of the present utility model: The horizontal reaction plates of these three flocculation reaction tanks are all designed in a horizontal installation form. Two horizontal reaction plates form a group structure, which is convenient for installation. The flocculation reaction tank uses horizontal reaction plates to realize the alternating changes of the water flow pattern and water flow velocity in the reaction tank, improves the reaction efficiency of the flocculation reaction tank, obtains a more ideal flocculation effect, basically completely solves the problem that the effluent quality deteriorates with the extension of the operation time, and the effluent water quality is further improved compared with the existing flocculation reaction tank.
