Description
Technical field
The present invention relates to field of waste water treatment, be specifically related to a kind of downdraft Magneto separate settling vessel.
Background technology
At present, along with the sustainable development of economy, the destruction of people to water environment is also on the rise, and is especially to live or the pollution of industrial wastewater, how to process life and to produce and industrial wastewater has become the problem needing solution badly; Magnetic suspension flocculate in water is separated mainly through the effect of magnetic field force by the Magneto separate settling vessel of current employing, and current, Magneto separate settling vessel mainly comprises following a few class:
1, high gradient magnetic separator: obtain magnetic field with winding around energising in equipment periphery, magnet steel hair is gathered for medium with high saturation magnetic induction stainless steel at device interior, when the magneticaction of the pollutant in waste water to steel wool is greater than its viscous drag and Action of Gravity Field, pollutant is trapped within steel wool medium, after cut-out magnetic circuit, magnetic force disappears, and the pollutant water trapped by steel wool medium or air-water backwashing get off, thus reach the object removing pollutant from waste water.Advantage: magnetic field intensity is adjustable, effective by filtering interception function post processing.Shortcoming: steel wool easily blocks, hydraulic power requires large; And steel wool Long contact time water quality, easily cause corrosion; Spoil disposal needs backwash, easily produces the mud mixture of secondary; Magnetic field relies on energising to obtain, and in processing procedure, power consumption is large; Dismounting trouble.
2, magnetic drum separator: at rotary drum internal placement magnet, relies on the rotation of magnetic drum to be adsorbed onto on rotary drum by the magnetic flocculate in water and scrapes with scraper, realize centrifugation.Advantage: long time continuous working.Shortcoming: power consumption; Flocculate in water is easily smashed by the rotation of rotary drum, disturbance, makes water outlet muddy, affects treatment effect, requires that higher situation is inapplicable especially for micro-polluted water, treatment effect.
3, permanent magnetism material filling type separator-filter: Nd-Fe-B permanent magnet is placed in cylinder inner hub location, and place metal filtration sheet wherein, realize adsorption filtration effect.Advantage: power saving; Water flow stationary.Shortcoming: magnet fixedly mounts, because magnetic field absorption affinity is strong thus spoil disposal is more difficult, needs secondary counter to rinse.
4, superconducting magnetic partition method
Superconductor, under a certain critical-temperature, has electric conductivity completely, and namely resistance is zero, does not have thermal losses, thus can use big current, thus obtain very high magnetic field intensity.As obtained with superconduction the electromagnet that magnetic field intensity is 2T.In addition, superconductor also can obtain very high magnetic gradient.
The feature of superconducting magnetic filter is: can obtain very high magnetic field intensity and magnetic gradient, electromagnet does not generate heat, and power consumption is less, and running cost is lower, and can make can the magnetic filter of continuous operation.But superconducting magnetic is because apparatus expensive be not suitable for Small Washing parking lot.
Above-mentioned Magneto separate settling vessel respectively has its pluses and minuses, has used inconvenience.
