Description
Technical field
The invention belongs to the water treating equipment technical field.
Background technology
The whipping device that is applied at present in the sewage aeration pond mostly is conventional whisk, comprising whipping devices such as rotating disk aerator, brush aeration machine, micro-hole aerator and the impeller of falling umbrella surface aerating machines.There are many shortcomings in above aerator in the middle of the practical project operational process:
1, in the sewage disposal for preventing the aeration tank sludge settling, equipment is selected mostly to be powerful blast aeration equipment, and multiple devices move simultaneously, has increased running cost and energy consumption.
2, owing to adopt large-scale blast apparatus, arrange accordingly increases construction investment than the big drum Ventilator Room.
3, adopt in the middle of the process of conventional aerator oxygenation in water, have only seldom that portion water contacts with air, this moment, most bubbles did not reach the desired bubble scale of oxygen transfer, and factor such as air pressure seriously restricts the efficient that oxygen shifts simultaneously.
4, the rate of transform of traditional aerator oxygen is lower than 20%, causes the energy about 60% to be wasted, and the cost of sewage disposal straight line rises.
5, the traditional technology aerator designs longlyer on aeration time, and former because oxygen transfer rate is very low, for reaching the purpose that enough oxygen is provided, so prolong aeration time, increases causing handling the structures volume simultaneously.
6, because traditional technical equipment is bulky, difficulty, complicated in mechanical structure, repair and maintenance difficulty are installed, bring inconvenience to production run.
Summary of the invention
The objective of the invention is:
A kind of axial flow type self oxygenated aerator for activated sludge is provided, it have simple in structure, treating water is effective, the time is short, it is low to consume energy.
Technical scheme of the present invention is:
Be provided with stir shaft in pool center place vertical direction, the stir shaft bottom is fixed with stirring blade, the stir shaft top cooperates with the power motor transmission by deceleration device, vertical direction also is provided with ventpipe at the pool center place, and ventpipe is communicated with air compressor machine, and mouth is communicated with distribution device at the bottom of the ventpipe.
Distribution device is arranged in the bottom of stirring arm.
Distribution device is an annular coil pipe of taking vent hole out of.
Distribution device is a radiation pipe of taking vent hole out of.
Stirring arm can one to several layers be arranged.
The invention has the beneficial effects as follows:
1, on aerator, is provided with whipping appts simultaneously, the energy feedwater flow is provided, with flowing of current in the maintenance aeration tank;
2, the air capacity that aerator provided is saved air capacity to satisfy the biochemical reaction demand for definitely;
3, reduce large-scale blast apparatus, reduced the air blast machine room simultaneously, reduced construction investment.
4, air compressor machine oxygenation in water is even, and bubble scale is moderate, by the stirring action of agitating vane, bubble is divided in the 0.5-1.0mm particle size range, makes the transfer efficiency of oxygen in water reach 50-60%.
5, because the stirring of stirrer makes sludge suspension in water, reduce the required air quantity of sludge suspension, reduced equipment scale, reduced facility investment.
6, by the stirring action of stirring rake, current form strong vortex in the aeration tank, make underwater bubble with eddying motion, and prolonged the residence time of air in water this moment, are the raising of the oxygen transfer rate condition of providing convenience.
7, the continuous stirring of stirring rake, the continuous motion of vortex makes active sludge be in suspended state in water, constantly grows up.When guaranteeing the aeration effect, reduce the design aeration time, reduce to handle the structures size.
8, axial flow is lower from oxygenation active sludge aerator integral device power, and energy consumption is low, only is 1/10 of equal scale conventional equipment energy consumption, reduces cost of sewage disposal.
Equipment stirs the efficiency of oxygen supply height, compact overall structure, and floor space is little, and is easy for installation, stable, easy and simple to handle, reduced investment.

Embodiment
Embodiment 1:
Power motor and air compressor machine can be divided under the liquid arrange and liquid on arrange, aerator by independent air compressor machine (gas blower) as source of the gas; Stirring rake can be provided with one deck or multilayer, and wherein the aerating apparatus blast main can be coaxial with whipping appts, but disalignment again; The single assembly service area is at 0.5 * 0.5m
2-10 * 10m
2Between the fluctuation.
Air compressor machine (gas blower) is worked simultaneously with stirrer, at air compressor machine constantly in water in the process of oxygenation, under air screen cloth and stirring rake acting in conjunction, constantly air filled cavity is divided into the 0.5-1.0mm bubble, air is contacted strongly with water, stirrer mixes fully, make small air bubble be diffused into each part of water body fully, reach the purpose of efficient dissolved oxygen in water.The continuous stirring of stirring rake, current form strong vortex, form convection current, prolong the residence time of air in water, the enhanced granule collision.Make active sludge be in suspended state simultaneously.The enhancement process effect.
