Embodiment
Air lift process is the process of a mass transfer, and material mass transfer effect is that forward is relevant to mass transfer area, mass transfer coefficient, the concentration difference of material in water and in gas phase, Henry's constant.
The concentration difference of material in water and in gas phase is the motivating force of mass transfer, and volumetric flow of gas is larger with the ratio of wastewater volume flow, and concentration difference is larger.But volumetric flow of gas does not possess significant adjustability with the ratio of wastewater volume flow, and this parameter this in actually operating in safety range by within computer capacity.
Henry's constant and temperature are proportionate, and improve temperature and can strengthen air lift effect, but make troubles to the off gas treatment in later stage, and can increase manufacturing cost.
The turbulent flow of mass transfer coefficient and water is proportionate, and turbulence level is larger, and material mass transfer effect is better.So improve the flow velocity of waste water, the turbulence level of waste water can be strengthened.
Material mass transfer effect is directly proportional to mass transfer area.Mass transfer effect is directly proportional to droplet surface is long-pending, and droplet is less, and droplet surface is long-pending larger, and gas phase contacts more abundant with liquid phase.The size of droplet becomes inverse relation with the radius of brush pin with the circular frequency of brush pin, and the circular frequency of brush pin is directly proportional to revolution.In other words by improving motor rotations, droplet can be made tiny, and mass transfer effect is better.
Below in conjunction with embodiment shown in the drawings, the present invention is described in detail below.
Embodiment one
As shown in Figure 1, this Moveable horizontal air-lift device comprise drum-shaped main box 1, be rotationally connected with in main box 1 and for sewage being broken into vaporific brush roll 2, the motor 3 that is used for driving brush roll 2 to rotate, be arranged on support 6, droplet collector 4 bottom main box 1.
The bristle of the below of described brush roll 2 is immersed in sewage, described main box 1 offers inlet mouth 11/ air outlet 12 for air entry/exit, described main box 1 also offers the water-in 13 for sewage entry/exit and water outlet 14, described inlet mouth 11 and air outlet 12 are arranged on the top of water-in 13 and water outlet 14.Air mixes more abundant with vaporific sewage, and material mass transfer effect is better.Therefore in order to make air fully mix with vaporific sewage, described water-in 13 is opened on the same end face of main box 1 with air outlet 12, and described water outlet 14 and inlet mouth 11 are opened on the end face relative with water-in 13 place end face.
The filtration procedure of this Moveable horizontal air-lift device is as follows: sewage is broken into vaporific by the bristle of brush roll 2 after entering casing 1 by water-in 13, meanwhile, air enters casing 1 and vaporific sewage by inlet mouth 11 and drips and fully mix and carry out the mass transfer of material, in mass transfer process, VOC during sewage drips and benzene homologues are taken out of from air outlet 12 by air, and the sewage reaching emission standard after filtering directly is discharged from water outlet.Because the air carrying VOC and benzene homologues that not only has flowed out from air outlet 12 also has vaporific sewage to drip, therefore on air outlet 12, be also connected with droplet collector 4.Described droplet collector 4 comprises auxiliary box body 41, be opened in the droplet admission port 42 of side, auxiliary box body 41 bottom surface, be opened in the end face of auxiliary box body 41 and be positioned at the outlet port 43 of the side relative with droplet admission port 42.The end face of described auxiliary box body 41 is provided with and extends vertically downward but the overhead gage 44 do not contacted with bottom surface, the bottom surface of described auxiliary box body 41 is provided with extend vertically upward but contact with end face lower baffle plate 45, the bottom of described lower baffle plate 45 offers for the sewage backflow liquefied in auxiliary box body 41 to the leak-off chute 46 of main box 1.After the air and vaporific sewage that carry VOC and benzene homologues drip and flow to auxiliary box body 41 by air outlet 12, vaporific sewage drips and can drip by the larger sewage of liquefaction formation on casing 41 inwall, overhead gage 44 and lower baffle plate 45, larger sewage drips and can be back in main box 1 from air outlet 12, and the air carrying VOC and benzene homologues is then directly discharged to air from outlet port 43.
For improving the effect that sewage is atomized, in the present embodiment, the bristle length be immersed in sewage of the below of described brush roll 2 is 1cm.
In sum, this Moveable horizontal air-lift device compared with prior art has the following advantages:
1, horizontal type structure, make it put into freight container, volume is little, significantly saves space;
2, because its volume is little, therefore maneuvering ability is high, can treatment in situ groundwater pollution and wastewater from chemical industry;
3, atomizing effect is good, and expansion mass transfer area, multiple stage circulation, efficiency are high by 99.99%;
4, significantly reduce the pressure-losses, reduce energy consumption;
5, structure is simple, and without the equipment unit of traditional gas stripping column, manufacturing cost greatly reduces;
Even if 6 during high and iron manganese content height in waste water hardness, can not there is fouling, sintering and obstruction, have self-cleaning function;
7, enough wastewater treatment flows;
8, compact type, integration, miniaturization;
9, maintenance cost is low.
