|Professional and efficient/small shallow air floation machine/experiment device/wastewater treatment air flotation equipment workbench
The technique and equipment of solid-liquid separation is one of the key programs in water supply and drainage technique. The flotation is one the most efficient ways for removing the suspended particles whose specific weight is nearly equal to water.
This equipment is widely used in water supply and drainage technique.First,be used to remove the algae and descend turbidity by the waterworks with the water source from lakes. Second,be used in the industrial wastewater projects,such as,the field of petrochemical industry,spinning,printing and dyeing,electroplating,food and so on.Third,be used to recycle the useful material,such as,the fiber recycling from the field of paper making pulp and so on.
2.Representation of type
·The valid depth of water is very swallow,about 400~750mm
·The retention time of water power in pool is short（3~5min）
·The amount of purification is large,i.e surface load is high.
·less occupied area,light unit load,the assembly of all prefabricated part need no operation room,the equipment can be overhead insulated or multi-layer compounded.
·The installation charge is low and easy to be clean.
·The level of purification is high,aquatic plants and other suspended matter can be removed over 90 %,the remain mud after concentration is up to 35%.
·This device adopts GFA dissolved air system.Its structure is ingenious, its rate of dissolved air reaches up to 90 %, its volume is only one fifth of common dissolved air system,and it has the strong anti clogging capacity which is not possessed by other dissolved air devices.
4.Structure and working process
The whole equipment is cylindrical with compact structure and shallow pool. It contains pool body, rotating water distribution mechanism, dissolved air releasing mechanism, rotating frame, catchment mechanism, skimming mechanism, dissolved air system, backwater piping and electric control cabinet etc. Water inlet, water outlet and sludge outlet all are in the device's rotating area,water distribution mechanism, catchment mechanism,dissolved air releasing mechanism all is firmly connected with frames,rotating around the center of pool body so as to make the equipment reach the best state.
Air floating separation technology refers to the air and water make maximum the air dissolve into water under a certain work pressure, and strive to be in saturation state, and then release the pressure dissolved air water formed by reducing pressure, produce a large number of micro bubbles, which fully contacts the suspension flocs in water, then make the suspension flocs in water adhere to the micro bubbles, and float to the surface with bubbles together, finally form and strickle the scum to purify the quality of water.
The efficient shallow flotation equipment researched and developed by our company is a kind of advanced rapid air flotation equipment,which based on the traditional air flotation theory,and successfully applied "shallow theory"and"zero-speed theory",through the elaborate design,integrated the flocculation,air flotation,skimming,precipitation and scraping sludge,and it is also a kind of efficient equipment for water purification treatment.
Technological process sees Fig1;main technical parameter sees Table 2;the parameter about equipment piping of series of configuration sees Table3; series of parameter of equipment steel pool configuration's embedded part sees Table 4;series of parameter of equipment cement pool configuration's embedded part sees Table 5;outline drawing of equipment sees Fig 2 and Fig 3;equipment piping system sees Fig4 and Fig5;embedded part of equipment sees Fig 6 and Fig 7.
The whole WQF type of efficient shallow flotation equipment integrated the coacervation,air flotation,skimming,precipitation and scraping sludge,and its whole equipment is cylindrical with compact structure and shallow pool. Main body of this device is composed of pool body, rotating water distribution structure, dissolved air releasing mechanism, rotating frame, catchment mechanism and so on.The water inlet,water outlet and sludge outlet all are in the central area of pool body, water distribution mechanism,the catchment mechanism,dissolved air releasing mechanism all is firmly connected with frames.
This device offers a whole set of equipments and control system,through combining concentration control and disjection control,to strive to be in saturation state.(relevant details see Fig1 and Fig2)
