High density micro vortex inclined plate
High density micro vortex inclined plate sedimentation equipment
The main principle of the high-density micro vortex inclined plate sedimentation equipment is to comprehensively use the sedimentation mechanism and contact flocculation mechanism to complete the particle separation process in the sedimentation tank. On the basis of fully utilizing the sedimentation mechanism, the equipment is equipped with a vortex intensity control area in the equipment to reduce the large vortex intensity in the water flow at a certain position below the sedimentation equipment in the sedimentation tank and reduce the pulsation of the water flow in the sedimentation area. When the water enters the equipment, the special performance of this structure further controls the process of contact flocculation. In the process of constantly changing the flow rate and flow pattern, the probability of alum particles contacting and colliding in the equipment is increased, and they are connected by adsorption. Only alum particles whose size and density are sufficient to overcome the water jacking force and other related factors can sink. In the process of continuous sinking, alum particles with small particle size are continuously adsorbed until they are separated from the sedimentation equipment. When the alum flower gravity maintains a dynamic balance with the water flow jacking force and related forces, the contact flocculation sedimentation effect is enhanced, and a dense, impact resistant, automatic renewal and short renewal cycle dynamic suspended sludge layer is formed at a certain position in the equipment, so that the suspended sludge layer always maintains a strong filtering, adsorption and sewage receiving capacity, and the sedimentation effect is better.
The thick ethylene propylene copolymer plate and supporting profile used for the inclined plate have the rigidity unmatched by the ordinary inclined plate and inclined pipe, and are resistant to heavy load and deformation; The raw materials of the equipment are food grade polypropylene and polyethylene, which are synthesized according to a certain proportion, supplemented by hydrophobic agent, with good hydrophobicity, smooth surface, avoiding alum adhesion and facilitating sludge discharge; Compared with ordinary inclined plate (pipe), high-density inclined plate has a higher inclination angle, further improving the sludge discharge speed. The inclined plate has no lateral constraint, which is more conducive to the sedimentation and separation of flocs. The inclined plate equipment is made of ethylene propylene copolymer and assembled by hot melt welding. The distance between inclined plates is small and the thickness of the plate is large, so the strength is high and the service life is long (more than 10 years).
The internal part of the inclined plate sedimentation equipment conforms to the hydromechanical properties, with beautiful appearance, smooth surface for sludge discharge, large rising velocity, high surface load, convenient installation, small flow resistance, and good sedimentation effect and filter screen capture. By restraining the pulsation of water flow, the sedimentation efficiency is improved, and the sludge discharge effect is good. The rising velocity of sedimentation tank is up to 2.5~3.5mm/s, and the effluent quality is guaranteed to be below 3NTU, which is stable at about 1NTU for a long time. It can replace reverse flow inclined plate, high efficiency composite inclined plate, inclined pipe, lateral flow inclined plate (pipe), horizontal pipe, horizontal flow sedimentation tank, high-density sedimentation equipment and sedimentation equipment of clarifier.
