Description
Technical field
The invention belongs to and adopt magnetically separating and purifying liquid technical field, particularly a kind of magnet ring liquid purification equipment.
Background technology
In the production process of metallurgy, mine, electric power, oil and chemical industry, produce a large amount of waste water, environment has been caused to serious pollution.In order to address this problem, for magnetic waste water (iron content suspended substance), magnetic separation technique has become a kind of known technology that is suitable for such wastewater treatment; And for non magnetic waste water, also start in recent years to adopt magnetic separation technique to process, first add magnetic and medicament, make magnetic and Pollutants in Wastewater flocculation agglomerating, with magnetic separating apparatus, from waste water, the agglomerating impurity absorption of flocculation is separated again, to realize useless water purification.No matter be to process magnetic waste water or non magnetic waste water, the key of magnetic separation technique is the performance of equipment itself, comprises water outlet concentration of suspension, processing power, the level of automation of operation, and floor space continuously, cost of investment etc.
At present, the magnetically separating and purifying waste fitment in engineering application mainly divides three kinds by the integration mode of permanent magnets, and the one, bar magnet isolation of purified equipment, the 2nd, magnet drum isolation of purified waste fitment, the 3rd, magnet ring isolation of purified waste fitment.Bar magnet isolation of purified equipment magneticstrength is high, be suitable for the separation of ultra-fine magnetic impurity, but slag dumping is cumbersome, is difficult to adapt to the continuous processing requirements of big yield; Magnet drum isolation of purified equipment by magnet drum and a wastewater trough, scrape slag sheet and form, wastewater streams is through magnet drum outside surface, the Magnetism granule in waste water (or magnetic floc sedimentation) is by magnet drum fractionation by adsorption; Magnet ring isolation of purified waste fitment is combined by a plurality of magnet rings, and permanent magnets used is rare earth permanent magnets forever, and wastewater streams is space through between magnet ring, and the ferromagnetic particle thing in waste water is adsorbed by magnet ring, and waste water is purified.
As disclosing, Chinese patent ZL92214041. 3 a kind ofly " processes the permanent magnetism separating treatment equipment of steel plant wastewater; and ZL00222525. 5 discloses a kind of " rare earth magnetic isolation of purified equipment "; although that these devices have magnetic intensity is high; gradient is large; between dish, flow time is long; fractionation by adsorption effect is compared with advantages of higher, but it exists technical process long simultaneously, floor space is large, and one-time investment volume is large, and operation stability is poor, processing power limited, and be subject to the impact of water quality and quantity variation greatly, Comparison of Management is complicated, and equipment failure is many; Also there is the permanent magnet flocculator of employing to carry out treatment process to sewage, Chinese patent 200720184904.X discloses a kind of permanent magnet flocculator of sewage scale removal, this magnetic apparatus for eliminating sludge has improved wastewater purifying efficiency greatly, but exist magnetic field layout unreasonable, a little less than middle magneticstrength, the Bian Bichu of flocculator still can produce magnetic force blind area, impact magnetization effect; Patent ZL92108011. 5 discloses a kind of magnet ring isolation of purified waste fitment, this equipment is combined by a plurality of magnet rings, and permanent magnets used is rare earth permanent magnets forever, and wastewater streams is space through between magnet ring, ferromagnetic particle thing in waste water is adsorbed by magnet ring, and waste water is purified.But the deficiency that this equipment existence and magnetic bar type and drum-type magnetic separating apparatus are same: the permanent magnets in equipment is just partially immersed in waste water, fail to give full play to the slag absorbing ability of whole permanent magnets, thereby the cost of investment of equipment, floor space all fail to reach optimum.On the other hand, all there is the problem of capacity of resisting impact load deficiency in magnetically separating and purifying waste water plant known today, and, when waste water dregginess fluctuates when large, water outlet concentration of suspension may increase, and is difficult to guarantee that effluent quality meets the requirements.
Summary of the invention
Weak point for the magnetically separating and purifying waste fitment in existing engineering application, the invention provides a kind of slag absorbing ability that can simultaneously give full play to magnetic flco natural subsidence effect and permanent magnets, and have treatment capacity greatly, be not subject to feedwater quality restriction, stable effluent quality, occupation of land less, the water body purification apparatus of the aspect advantage such as cost of investment is low, capacity of resisting impact load is strong, continuously-running, i.e. magnet ring liquid purification equipment.
To achieve these goals, the present invention has adopted following technical scheme:
