Description
Technical Field
The utility model belongs to the technical field of water treatment, and particularly relates to demagnetizing equipment for magnetic core recovery.
Background
The magnetic flocculation technology (or supermagnetic separation technology) in water treatment is to flocculate and coagulate pollutant in water into magnetic floc by means of the flocculation and coagulation of magnetic core (or magnetic powder or magnetic seed), coagulant and pollutant. The magnetic micro floccules overcome the resistance of fluid and self gravity by the high-strength magnetic field generated by the super-magnetic separation equipment under the action of the high-strength magnetic field, and are adsorbed on the surface of the magnetic disk, so that the purpose of solid-liquid separation is achieved. The method can also utilize the flocculation containing the magnetic core with larger density and better sedimentation property to sediment the flocculation in a sedimentation mode so as to achieve the purpose of solid-liquid separation. In any mode, the separation of the sludge and the water body can be realized, so that the aim of purifying the water quality is fulfilled. In either way, the magnetic sludge is subjected to magnetic core recovery equipment to realize separation of the magnetic core and the sludge; the separated magnetic cores are recycled continuously to participate in the next flocculation process, so that the cost is saved by recycling.
The recovered magnetic core is sent back to the flocculation reaction section to participate in a new round of reaction and is recycled. The existing mode is to directly add the magnetic core (or called magnetic powder or magnetic seed) to participate in a new round of reaction, and the demagnetizing treatment is not carried out on the magnetic core, so that the magnetic core has poor dispersibility, the combination of the magnetic core and flocs during flocculation reaction is seriously influenced, and the subsequent solid-liquid separation effect is influenced.
The flocculation reaction takes the magnetic seeds as condensation cores, and the flocculation reaction takes part in the reaction at each stage of bridging, adsorption, trapping and the like of flocculation and is tightly combined with floccules, so that the floccules have increased density and magnetism, and the subsequent magnetic separation or precipitation process can be smoothly implemented. Therefore, the magnetic core is required to have proper granularity, generally 200-400 meshes, and the treatment effect is affected when the size is too large or too small. The recovered magnetic core is magnetized by a strong magnetic field, and partial magnets in the magnetic core are changed from disorder to order, so that the magnetic core presents certain magnetism. The recovered magnetic seed particles are mutually adsorbed to form larger particles under the influence of magnetism, when the magnetic cores of the large particles participate in the reaction again, the sedimentation rate is too high due to the fact that the particles are too large, flocculation reaction participation effect is greatly influenced, flocculation is very difficult to be achieved, the flocculation is difficult to be trapped into components of the flocculation when the flocculation is generated, the magnetic cores are directly absent in the flocculation, and therefore the performance of magnetic attraction and sedimentation is reduced, and the separation of the flocculation and the water body is seriously influenced.
