Examples
As shown in fig. 1 to 2, the present embodiment provides an air stripping device, including: a liquid lifting pipe 7, a gas-liquid separator 4, a water outlet pipe 1, an air distribution pipe 6 and the like.
In the example shown in fig. 1, the lift tube 7 has one end for vertically extending below the external liquid level 5 of the gas stripping device, and when applied to a biochemical reactor, the external liquid level 5 of the gas stripping device is the liquid level in the tank of the biochemical reactor.
The gas-liquid separator 4 is connected with the other end of the riser pipe 7 and is provided with an opening for exhausting gas; the water outlet pipe 1 is connected with a gas-liquid separator 4; the gas distribution pipe 6 is arranged by sequentially penetrating the gas-liquid separator 4 and the liquid lifting pipe 7 from the opening. The end of the riser pipe 7 that extends below the liquid surface has a water inlet 8 for providing a passage for the external liquid surface 5 to enter the riser pipe 7.
The liquid lifting pipe 7, the gas-liquid separator 4 and the water outlet pipe 1 are all made of conventional pipes and pipe fittings and are detachably connected.
During the application, with lift pipe 7 vertical stretch into in the outside liquid level 5 of air stripping device under to submerge to take the altitude, wear vapour and liquid separator 4 with gas distribution pipe 6 and descend to a certain position to lift pipe 7, have the certain distance apart from water inlet 8, and gas distribution pipe 6's size design needs to have predetermined interval with lift pipe 7 inner wall after penetrating, connects the air pump with compressed air interface 2 that gas distribution pipe 6's inlet end was equipped with. The air pump is started to work, because the air lifting device is immersed in liquid, air enters the liquid lifting pipe 7 from the air distribution pipe 6 and is mixed with biochemical sludge, the density of the air is about 0.25-0.35, so that density difference is formed between the inside and the outside of the liquid lifting pipe 7, liquid in the liquid lifting pipe 7 rises under the action of density flow and then enters the gas-liquid separator 4 from the upper end of the liquid lifting pipe 7, the gas-liquid separator 4 is realized in the gas-liquid separation tank, the gas is upwards discharged into the atmosphere through the opening, the liquid is discharged from the water outlet pipe 1, and the air lifting height is close to the depth of the air distribution point of the air distribution pipe 6 from the liquid level.
Because the air distribution pipe 6 penetrates through the gas-liquid separator 4 and the liquid lifting pipe 7, when the air distribution pipe 6 is to be cleaned or overhauled, the air distribution pipe 6 can be easily drawn out without taking out the whole air lifting device, and the air inlet joint is above the liquid level, so that the installation is extremely convenient. If adopt the independent external condition of prior art's gas distribution pipe 6, when needs wash or overhaul, for inconvenient, need establish the special gas distribution pipe 6 of supplying of opening in addition and take out to this kind is taken out and the disturbance range that penetrates great inevitable, is not injectd in lift tube 7, will cause the influence to the outside liquid of air stripping device, and is unfavorable to biochemical reaction.
As a specific implementation mode of the example, the section of the gas distribution pipe 6 located on the riser pipe 7 is provided with a plurality of gas distribution holes 61, the gas distribution holes 61 are arranged at the lower section of the gas distribution pipe 6, the orifices of the gas distribution holes point to the inner wall of the riser pipe 7, and the gas distribution holes 61 are all located at the same height. The air distribution hole 61 is arranged at a preset distance from the end of the air distribution pipe 6 positioned on the lift pipe 7. For example, a plurality of small holes with the diameter of about 2-6mm are arranged on the side surface of the cylinder at the position which is about 30cm upwards from the lower end of the air distribution pipe 6 at the same height to be used as air distribution holes 61. The setting is at same height, does benefit to the validity that keeps the air stripping, avoids the interference that misplaces from top to bottom and sets up and lead to, and the setting in aperture does benefit to effectively providing the air current and impurity in the reducible liquid blocks up to gas distribution pipe 6 simultaneously.
In the specific implementation mode of the example, the diameter of the lift pipe 7 at the joint of the lift pipe 7 and the gas-liquid separator 4 is smaller than that of the gas-liquid separator 4. Through the reducing treatment, the slow flow effect is achieved, and the phenomenon that the continuous liquid level in the gas-liquid separation tank is too high due to too fast liquid lifting is avoided.
As a further implementation mode, the water outlet pipe 1 is connected to one side of the gas-liquid separator 4, the joint of the water outlet pipe 1 and the gas-liquid separator 4 is a preset distance away from the joint of the liquid lifting pipe 7 and the gas-liquid separator 4, through the structural design, the rising liquid is accumulated in the gas-liquid separator 4 at a certain height and then flows into the water outlet pipe 1, and due to the existence of the section of liquid column, the phenomenon that the escaping gas drives the liquid to be sprayed out from the opening at the top of the gas-liquid separator 4 can be avoided by means of a liquid sealing.
All structural parts of the gas stripping device are made of corrosion-resistant materials, preferably plastic or stainless steel materials, the gas stripping device is durable, can be used for extracting fluids such as acid liquor, alkali liquor and the like besides activated sludge, and is particularly suitable for working under acid-base environment conditions.
The air lifting device is simple in structure, all parts are standard pipe fittings and pipes, and the air lifting device can be manufactured by slightly combining the parts.
