Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example 1:
referring to fig. 1-2, a gravity flow folded plate flocculation and sedimentation device comprises a flocculation tank 6 and a sludge tank, wherein the flocculation tank 6 is of a flat spiral structure, the flocculation tank 6 comprises a tank wall and a tank bottom, the tank wall and the tank bottom are of a concrete structure, the sludge tank is arranged at the bottom of the tank wall of the flocculation tank 6, and the sludge tank is connected with the flocculation tank 6 through a discharge pipe;
the discharge pipe is made of plastic, and a discharge port of the discharge pipe is vertically arranged with the bottom of the sludge tank;
one end of the discharge pipe is connected with a sewage discharge port of the flocculation tank 6, and a valve is arranged between the discharge pipe and the sewage discharge port and is made of plastic;
a plurality of groups of folded plates 2 are fixedly arranged in the center of the flocculation tank 6, the folded plates 2 are parallel folded plates or corrugated plates, and adjacent folded plates 2 are connected end to end;
both ends in the flocculation tank 6 are provided with bearing columns 3, and the bearing columns 3 are fixedly connected with the inner side threads of each layer of flocculation tank 6;
the upper end and the lower end of the flocculation tank 6 are respectively provided with a water inlet 1 and a water outlet 5, and the outer edge of the flocculation tank 6 is fixedly connected with a baffle 4;
when the utility model is used, water flow enters the flocculation tank 6 from the water inlet 1 and then flows downwards along the spiral flocculation tank 6 under the action of gravity, the folded plate 2 arranged in the flocculation tank can make the water flow generate effective collision for many times, and finally the flocculation process is smoothly finished and the water is discharged from the water outlet 5, so that the quality of the discharged water is improved;
the spiral flat flocculation tank 6 not only improves the space utilization rate, but also can accelerate the impact of water flow and the folded plate 2 by the circulation tank body under the action of gravity flow and the action of gravity, so that floccules are quickly flocculated, and the formation of a flocculating body can be accelerated when the water flow passes through a bend;
the folded plate flocculation tank is constructed by placing a certain number of parallel folded plates or corrugated plates in the tank, mainly using the wall-attached turbulent energy consumption mode generated by boundary layer separation caused by the scaling or turning of the folded plates 2, and keeping the input of trace and enough energy in the flocculation tank 6 along the way, thereby effectively improving the utilization rate of input energy and the volume utilization rate of coagulation equipment, increasing the relative movement of liquid flow, shortening the flocculation time and improving the sedimentation performance of a flocculating constituent;
the mathematical description of flocculation is generally divided into two separate processes: migration and adhesion; the migration process produces particle collisions, and the migration is caused by the velocity difference of particles in water, which in a folded plate flocculation basin is believed to be caused by: (1) the method comprises the following steps of (1) carrying out Brownian motion of particles (playing a main role in anisotropic flocculation), (2) carrying out turbulent vortex (cocurrent flocculation), (3) carrying out differential flocculation on the sedimentation velocity difference among the particles, wherein the adhesion depends on instantaneous acting force related to the surface property of the particles, the impact of the hydraulic property of a folded plate unit on floc particle collision is mainly shown in that the vortex-making effect of the folded plate unit and the continuous and uniform unit arrangement improve the distribution of turbulent energy consumption, so that the numerical value of a flocculation mode is improved, the flocculation effect is improved, water flow passes through the folded plate unit and can form symmetrical vortex and unilateral vortex under the action of a gradually expanding section and a gradually reducing section, the separation of a water flow boundary layer at a wave crest is a kinetic factor generating vortex, the separation is further decomposed into small-scale vortex according to the diffusivity of the vortex until the Reynolds number related to water flow micro-groups is low so that smaller vortex can not be generated any more, the large-scale vortex absorbs kinetic energy from the main flow and transfers the kinetic energy to the smaller-scale vortex in the movement process, and the kinetic energy is transferred step by step until the large-scale vortex reaches the micro-scale vortex; in larger scale vortex motion, the fluid viscosity is almost ineffective and negligible, and thus there is almost no energy consumption in the kinetic energy transfer;
in the micro-scale vortex motion, fluid viscosity plays a main role, energy transmitted to the lowest-level vortices is converted into heat energy through viscosity, countless large and small vortices exist in water flow at the same time, a series of pulse frequencies are generated, and a continuous frequency spectrum is formed; because the actual change range of the floc particle size is 1-1000um, a large section of vortex plays a role, and the limit of the large vortex and the small vortex cannot be strictly divided; the diffusion effect of the turbulence mainly depends on the turbulence with large scale, and the scale of the large vortex can be considered to be the same as the scale magnitude of the folded plate unit; the continuous scaling of folded plate unit makes rivers form the vortex of a large amount of different yards, has promoted the relative motion between the inside floc granule of rivers, has increased the collision chance, so for baffle flocculation basin, the flocculation effect improves greatly.
The above description is only the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution and the improvement concept of the present invention within the technical scope disclosed in the present invention.
