Abstract
The utility model provides a kind of new gas lifting gear, comprise inlet pipe and L shape riser pipe, the shank of inlet pipe and L shape riser pipe is positioned at below the liquid level of settling tank, inlet pipe linearly type is vertically placed and is positioned at the inside of L shape riser pipe, be provided with flange in the corner of L shape riser pipe, the inlet mouth of inlet pipe protrudes upward and air communication through flange.Inlet pipe is placed in riser pipe inside by the utility model, reduce the damage of inlet pipe on the one hand, on the other hand the free area of riser pipe is reduced, thus add in-pipe flow speed, bubble is not easily separated out from water, adopts the utility model to greatly facilitate maintenance and safeguard in addition.
Description
Technical field
The utility model relates to a kind of new gas lifting gear, belongs to technical field of sewage.
Background technology
Sewage can produce a certain amount of biochemical sludge in biochemical treatment process, is generally to pump in sludge sump by water pump by biochemical sludge, with pending.In order to reduce the investment of equipment and save running cost, utilize the Aeration fan in biochemical system, sometimes also adopt the mode of air lift to promote mud.The principle of airlift is the density difference utilizing liquid inside and outside riser pipe, makes sludge lifting.
Existing gas lift device as shown in Figure 1, have the following disadvantages in use: first, easily damage, and work-ing life is short by inlet pipe; Secondly, gas lift power is little, and sludge lifting speed is slow; Last not easy-maintaining and maintenance.
Utility model content
For above deficiency, the utility model provides a kind of new gas lifting gear.
The technical solution of the utility model: a kind of new gas lifting gear, comprise inlet pipe and L shape riser pipe, the shank of inlet pipe and L shape riser pipe is positioned at below the liquid level of settling tank, inlet pipe linearly type is vertically placed and is positioned at the inside of L shape riser pipe, be provided with flange in the corner of L shape riser pipe, the inlet mouth of inlet pipe protrudes upward and air communication through flange.
The bottom port place of inlet pipe is provided with bowl-shape end socket by bolt, forms air chamber between the upward opening of end socket and the outer wall of inlet pipe, and the inlet pipe being positioned at air chamber is provided with several air outlets.In use, end socket can ensure gas through air outlet, air chamber upwards discharges, and more easily forms the density difference of liquid inside and outside riser pipe.
Be provided with spacer in the periphery of inlet pipe or end socket, spacer for locating inlet pipe, to ensure giving vent to anger evenly in air outlet.
The beneficial effects of the utility model:
1. inlet pipe is placed in riser pipe inside, because riser pipe diameter is comparatively large and have enough intensity protection inlet pipe, therefore reduces the damage of inlet pipe;
2. inlet pipe is placed in riser pipe inside, takies the space of riser pipe, the free area of riser pipe is reduced, thus adds in-pipe flow speed, and ensure that liquid is in turbulence state all the time, and then bubble is not easily separated out from water;
3. the gas that air outlet sprays of former inlet pipe is right cylinder, and the gas that air outlet sprays of the utility model inlet pipe is torus, and gas-liquid initial contact area is increased, thus produces larger raising force;
4. inlet pipe and riser pipe are by Flange joint, and joint flange is positioned on the water surface, just inlet pipe the whole series can be taken out maintenance, do not need emptying rate of liquid in pond as long as opened by flange during maintenance; In addition, under liquid level, gas lift structure aneroid pipe, gas fittings, therefore maintain easily.
Accompanying drawing explanation
Fig. 1 is the structural representation of raw-gas lifting gear.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the structural representation of inlet pipe end.
Embodiment
As shown in Figures 2 and 3, a kind of new gas lifting gear, comprise inlet pipe and L shape riser pipe, the shank of inlet pipe and L shape riser pipe is positioned at below the liquid level of settling tank, inlet pipe 1 linearly type is vertically placed and is positioned at the inside of L shape riser pipe 3, be provided with flange 2 in the corner of L shape riser pipe 3, the inlet mouth of inlet pipe 1 protrudes upward and air communication through flange 2.The bottom port place of inlet pipe 1 is provided with bowl-shape end socket 7 by bolt, forms air chamber 4 between the upward opening of end socket 7 and the outer wall of inlet pipe 1, and the inlet pipe 1 being positioned at air chamber 4 is provided with several air outlets 5.Spacer 6 is provided with in the periphery of inlet pipe 1 or end socket 7.
During use, air enters through inlet pipe 1, discharges in riser pipe 3 through air outlet 5 and air chamber 4.Along with the gas in riser pipe 3 rises, form the density difference of liquid inside and outside riser pipe, and then make the mud in settling tank realize promoting.
Claims (3)
