Description

Activation type oxygen dissolved aerator
Technical field
The present invention relates to a kind of activation type oxygen dissolved aerator that is applicable to aeration oxygen replenishing in the sewage purification bioremediation, particularly adopt the magnetics biotechnology, rich poly-from air, activatory oxygen with fully combine through magnetized sewage, with the aerator of raising dissolution of contaminated water oxygen saturation.
Background technology
Exist a large amount of microorganisms at occurring in nature, they have the organism and the inorganics of oxygenolysis complexity, and these materials are changed into simple material, or toxic substance are converted into the ability of non-toxic substance.Facts have proved, utilize the organism in the microbiological treatment waste water, have less investment, efficient height, stable operation, working cost is low, and effluent quality is good, and sludge settling property is good, and can be used as advantages such as fertilizer.In bioremediation, activated sludge process is destitute of smell substantially with it again, the processing required time is short, handle characteristics such as rate of increase height and occupy extremely important status, in the method, aeration is absolutely necessary, its effect is well-off oxygen, and mixed solution stirred, make active sludge keep suspended state, so that contact mixing with waste water.
Aeration method commonly used both at home and abroad at present has the blast aeration method, mechanical mixing method and jet-flow aeration method etc., and its key equipment is based on centrifugal blower, Root's blower and various surface aerating machine, and power mostly is 290 kilowatts and 630 kilowatts, and weight is generally more than 3.5 tons.Activated sludge process, brought into use the ceramic capillary aerator from 1919, and the unlike material of the use of exploitation afterwards, dissimilar micro-hole aerators all because of technical problems such as micropore obstructions, influences its use.China begins from the seventies, introduces various types of blast aeration equipment, has successively developed the spiral aerator that is applied to the deep water aeration again, jet aerator etc., but problem such as the utilization ratio of ubiquity oxygenation capacity and oxygen is on the low side, and gas distribution is also inhomogeneous.
After the nineties, China is target to improve oxygen uptake rate and dynamic efficiency, develop out the aerator of this type of the present invention, as Chinese patent 94104389.4,97120975.8,99103087.7 and the disclosed oxygenation aerator of WO2006/102802, especially the disclosed aerator of WO2006/102802, obtained further improvement technically, occur to make but that processing request precision height, difficulty are big, during machine run vibrations big, problem such as parts depreciation is serious, the time between overhaul is short.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned problem, provide that a kind of oxygenation capacity is strong, saturation dissolved oxygen is high, make that processing is simple, dynamic efficiency is not only high, work-ing life but also long aerator.
The present invention seeks to realize like this:
Aerator of the present invention mainly partly is made up of stirrer, sewage magnetizing apparatus and gas injection device etc. in the water, and wherein: stirrer is to be made of submersible machine and the water screw of fixing on its output shaft in the water; The sewage magnetizing apparatus is by being inlaid in the permanent magnet on the water screw and being installed in the magnetization hydrophone that permanent magnet on the water conservancy diversion barrel around the water screw constitutes dynamic and static magnetic field; Gas injection device is transported to always by oxygen-rich air machine with oxygen-rich air that the gas pipe line of negative pressuren zone is formed under the water screw, and is fixed into a complete machine by various strut members.Feature of the present invention is that motor is pulled the plug, directly fixing with water screw, shortened the transmission of power distance of motor, also gas pipe line is divided into dynamic and static two portions simultaneously, be connected by the static and dynamic sealing junctor, guarantee the straight-through of gas pipe line, reduced many wearing and tearing workpiece, reduced the resistance of gas transmission.
Moving part about gas pipe line, the present invention is the tubular shaft that utilizes water screw, its air outlet is opened in negative pressuren zone under the water screw, further improving is at water screw centrifugal impeller to be installed behind, branch flow cone of centrifugal impeller center design, allow oxygen-rich air in the gas pipe line along the water screw tubular shaft, along the slope of dividing flow cone, be dumped in the deep water through centrifugal impeller.Oxygen-rich air is blasted by centrifugal wind wheel, is subjected to the suction of negative pressuren zone, throws away through water screw behind centrifugal impeller again, and it injects big reinforcement of great efforts of water.Therefore the gas injection rate of aerator of the present invention has increased greatly.
Oxygen-rich air machine among the present invention can adopt the magnetic force oxygen enriching machine, and magnetic force polyoxy device is installed before centrifugal wind wheel, and on the centrifugal wind wheel axle permanent magnet is installed vertically, rotates with the axis.
The present invention can also make the Lavalle barrel shape with the top of guide shell, sewage magnetizing apparatus fixed permanent magnet is inlaid in the waist of Lavalle tube.
The present invention can be with the base for supporting of submersible machine, cover on the outer support tube of guide shell, gas pipe line on the motor and support the chain-wales of oxygen-rich air machine, and is fixedly connected in aggregates, by buoyant spheres complete machine is suspended in the water.
The present invention adopts motor is pulled the plug, and uses technological improvement measures such as static and dynamic sealing junctor, has solved the existing problem of previous similar aerator significantly, and good result of use is arranged.
