Embodiment
The utility model mode of execution provides a kind of air-lift device, be used in the sewage disposal system mixed-liquor return is handled, finish backflow by mixed solution is carried out lifting mode, this device mainly comprises: riser, outlet pipe, air duct and air discharge several leading part and constitute; Set out water pipe on the riser; Air is set on the air outlet of air duct discharges head, the air outlet of air duct and the air on the air outlet discharge head and all are arranged in the riser, and the suction port of air duct is used for being connected with air feeder.When this device is applied in the sewage disposal system, water intake one end of riser is arranged in the treatment pond at mixed solution place, pressure air enters in the riser by air duct, discharge through air release head from the air outlet of air duct bottom, fully mix with the mixed solution in the treatment pond, because the proportion difference of the mixed solution in air water mixed solution and the treatment pond produces rising power, mixed solution is got a promotion by riser, the water outlet of the mixed solution that promotes in the riser on riser is discharged to the destination, finishes the reflow treatment of mixed solution.
For ease of understanding, air-lift device is described further below in conjunction with drawings and the specific embodiments.
Embodiment one
As shown in Figure 1, present embodiment provides a kind of air-lift device, is used in the sewage disposal system and finishes the mixed-liquor return processing with hoisting way, and this device specifically comprises:
Riser 1, outlet pipe 3, air duct 4 and air discharge 6; Set out water pipe 3 on the riser 1; Air is set on the air outlet of air duct 4 discharges 6, the air outlet of air duct 4 and the air on the air outlet discharge 6 and all are arranged in the riser 1, and the suction port of air duct 4 is used for being connected with air feeder.
Air feeder can adopt the air compressor of can regulate tolerance etc., but in practice, be saving equipment and electric energy, the suction port of air duct directly is connected with the aeration tube of sewage disposal system, directly introduce the used air of on-the-spot aeration as the gas that promotes usefulness, and discharge 6 sidewall and have several evenly distributed bar shaped apertures being connected cylindrical shape air on the terminal air outlet of air duct, the gas that is entered by air duct 4 discharges on 6 sidewall evenly distributed aperture by air and is radial and is discharged in the riser 1 like this, and air is fully mixed with mixed solution.Promote effect preferably for reaching, require the pressure in the air duct 4 should be greater than the pressure at least 0.3 meter of stone submersion (h); The minimum pipe (internal diameter) of general air duct is 25 millimeters, and the minimum pipe of stalk (internal diameter) is 75 millimeters.
