High efficiency three blade eddy current equipment
[Introduction]
High efficiency three blade vortex equipment is a new type of high efficiency flocculation equipment developed and produced in recent years. Due to its good hydraulic performance and convenient installation and maintenance, it is increasingly widely used in water plants, reclaimed water reuse projects, advanced treatment sections of sewage treatment plants and other projects, with significant social and economic benefits. Vortex reaction tank is the reinforcement of folded plate reaction, grid reaction and grid reaction. Vortex street reactor is set in the reaction tank perpendicular to the water flow direction to make the water flow generate high-frequency spectrum vortex, provide micro hydrodynamic water conditions for full contact between the agent and particles in water, and produce dense alum. The design shall be classified and controlled according to the reaction requirements. Therefore, ideal reaction effect can be obtained. The reaction time is short, only 8-12 minutes. The construction is simple, the installation is convenient, and the adaptability to changes in raw water quantity and quality is strong.
[Flocculation mechanism]
When a large number of vortex street reactors are placed in the coagulation reaction area, due to the relatively small flow rate in the reactor, a floc suspension area is formed inside the vortex street reactor in the upward flow area, and the suspended flocs flocculate the destabilizing colloid in the water flow. As there are suspended flocs in each vortex street reactor in the upward flow area, the total volume is large, forming three-dimensional contact flocculation: the flocs in the vortex street reactor have high growth quality, Under the action of eddy current, too large flocs will be broken into smaller flocs to maintain the flocculation capacity (too large flocs will reduce the total surface area and the adsorption capacity). The flocs with low density will be broken and re flocculated into higher density flocs under the action of micro eddy current, which is conducive to precipitation and separation.
[Features]
The high-efficiency three blade vortex equipment is equipped with vortex street device to better distribute water flow and enhance reaction effect. Vortex street reactor can make water flow generate high-frequency spectrum array vortex, and the alum produced is dense. The vortex street reactor equipment divides the reaction section into three stages. The first stage reaction is the most violent, which ensures the full contact between the agent and the particles in the water, creating favorable conditions for the formation of dense alum flowers. The flow rates of the second and third stage reactions gradually decrease, during which the dense alum flowers gradually form, and then flow slowly through two transition sections. The dense alum flowers enter the sedimentation tank, laying a good foundation for the subsequent sedimentation work.
The high-efficiency three blade eddy current equipment is of integral type, which is easy to install, simple to manage and maintain, and has strong adaptability to changes in raw water volume and water quality. It can adapt to difficult to treat high turbidity water, low turbidity water and slightly polluted water quality, and has stable flocculation effect. Vortex reactor equipment can rotate by itself under hydraulic conditions to prevent sludge and inhibit the growth of algae.
