Dissolved air flotation machine equipment (Qingdao) environmental engineering co., LTD., production is mainly used for solid - liquid or liquid - liquid separation of a water treatment and environmental protection equipment products.Air flotation device through the dissolved air and release system produces a large number of tiny air bubbles in water, medium density makes it stick in the waste water and the water close to the solid or liquid particles, the overall density less than the state of water, and to rely on buoyancy make it rose to the surface of the water, so as to achieve the purpose of the solid - liquid or liquid - liquid separation.
2. Working principle: by the air compressor to air tank of air through the jet device was brought into the dissolving tank, under the pressure of 0.35 Mpa were forced to dissolve in the water, the formation of dissolved air water, to air floatation tank.In the case of sudden release, separating out the air of dissolved in water to form the micro air bubble group, with and after dosing pump sent a good contact with suspended solids in flocculation of sewage, and in the process of slowly rising good suspensions of flocculant adsorption on set, make its density decreased and float to the surface, to achieve the purpose of the removal of SS and CODcr.
Characteristics of three.
1. The dissolved air pump suction while inspiratory, pump pressurized mixing, gas-liquid dissolving in high efficiency, small air bubbles or less 30 um.
2. Low voltage operation, the efficiency of dissolved air is as high as 99%, release rate as high as 99%.
3. The micro bubbles and high adsorption of suspended particles to improve the effect of the removal of SS.
4. The dissolved air water dissolving efficiency is 80-100%, three times higher efficiency than traditional dissolved air flotation.
5. The pressure - volume curve smooth, easy to realize automatic control, easy operation easy maintenance, low noise.
4. The main structure
1, air flotation machine: circular steel structure, is the main body and the sewage processor core, the internal release, uniform, sewage pipe, outlet pipe, sludge tank, scraping the city-state system, etc.
Release in the air floating machine central location, is the production of key components of the micro air bubble.Dissolving tank to dissolved air water mixed with waste water fully here, all of a sudden release, vigorous agitation and eddy current, form a diameter of about 20 to 50 um micro bubbles, and stick on the flocculation of waste water body, thereby reducing flocculation and increase the proportion of the body, separate water thoroughly.Outlet pipe are actually lower box body, and through a vertical head is connected to the upper box overflow, overflow outlet is equipped with water level regulating handle, facilitate adjustment tank water level.Drain pipe is installed in the bottom of the box body, to discharge the sediment deposited on the bottom.On the box body is equipped with the sludge tank, tank with scraper, scraper continuous rotation, continuous to floating sludge to sludge trough, gravity flow to the sludge in the pool.
2, the dissolved air system includes dissolving tank, storage tank, air compressor, high-pressure pump, dissolving tank is the most critical part of the system, work is not a good contact with air, accelerate the air dissolved.It is a closed pressure steel cans, internal design with dampers, spacer, can accelerate the diffusion of air and water, and mass transfer process, improve the efficiency of dissolved air.
3, cans, steel round cans, used to dissolve storage solution, two of them as the dissolving tank, with a stirring device, the other two for drug storage tanks, volume matching according to the capacity size.
5, the applicable scope dissolved air floating device suitable for:
Papermaking wastewater treatment and recovery fiber, printing and dyeing wastewater treatment, electroplating, etc all kinds of heavy metal ion wastewater, oil-bearing wastewater, leather wastewater, chemical waste water treatment, paint the biological treatment of wastewater, food wastewater treatment, the separation of mud and water, low temperature and low turbidity surface water treatment, wastewater containing algae surface water treatment, various solid and liquid separation, etc.
We are professional emission standards engineering equipment manufacturing cell and sludge in leadership brand, manufacturer primary source, short production cycle, product quality assured!
