Description

A kind of novel air stripping mentions mud device

Technical field

The utility model relates to sewage treatment technology fields, mention mud device more particularly, to a kind of novel air stripping.

Background technique

The sludge discharge way of biochemical system sedimentation basin mainly has a gravity spoil disposal and pressure spoil disposal at present, gravity spoil disposal mainly according to Carry out spoil disposal by the mode of liquid level difference, pressure spoil disposal is then to promote spoil disposal outward in the way of sludge pump, mud discharging and return The position of stream is mainly in bucket bottom.But both sludge discharge way are each defective, and such as: pressure sludge discharge way is used, due to Which employs sludge pumps, so sludge discharge effects are preferable, can also meet pressure required for reflux, this mode is generally usually used in Fairly large sewage treatment project, equipment investment and power consumption are big, and operating cost is high, and activated sludge floc is easy to be high The impeller of speed rotation smashes destruction, is not able to maintain its intrinsic characteristic；When using gravity sludge discharge way, often not due to liquid level difference Enough or bucket base sludge is excessively closely knit, so spoil disposal is easy to cause to have some setbacks；Both it is located under water, is frequently switching Failure is easy to appear during machine, it usually needs stop production draining, and maintenance is more troublesome, and cost is also high.

Utility model content

In view of this, the purpose of this utility model is in view of the deficiencies of the prior art, to provide a kind of tables of equipment one, maintenance side Just, the novel air stripping of economizing on energy and electricity mentions mud device, not only has agitating function, but also can effectively be mentioned to sludge and mixed liquor It rises.

In order to achieve the above objectives, the utility model uses following technical scheme:

A kind of novel air stripping mentions mud device, including steam line, in inverted "L" shape conveyance conduit and to be located at conveyance conduit curved Casing at pipe；The water inlet of the conveyance conduit is horn-like nozzle, and the steam line is inserted into conveyance conduit through casing, The gas outlet of the steam line extends to the water inlet of conveyance conduit, and is fixedly connected with aeration head by connector, institute The air inlet for stating steam line is connect with feeder.

Preferably, the aeration head is rounded, and diameter is consistent with the outer diameter of steam line.

Preferably, the aeration head is equipped with 3-8 solarization air cap.

Preferably, the aeration head is blind plate, opens up 4-8 exposure at away from its gas outlet 8-12cm on the steam line Stomata.

The beneficial effects of the utility model are: casing can not only fix steam line, but also it is possible to prevente effectively from mixed liquor or Sludge sprays conveyance conduit；The aeration tube of steam line and oxidation ditch bottom of trench shares blower, does not need individually to be equipped with power-equipment, Securely and reliably；The air lift mention mud device by using compressed air as power instead of traditional electric power sludge pump, save Operating cost, and activated sludge floccule body will not be destroyed during spoil disposal, sludge inherent characteristic can be effectively kept, is mentioned Dissolved oxygen content in high sludge, while also ensuring that spoil disposal is smooth；Various promotions can also be met by adjusting ventilatory capacity The working condition requirement of height.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the side view of the utility model；

Fig. 3 is the top view of the utility model.

In figure: 1 conveyance conduit, 2 steam lines, 3 casings, 4 horn mouths, 5 aeration heads.

Specific embodiment

The utility model is further described with reference to the accompanying drawings and examples.

Embodiment 1

As shown in Figure 1-3, a kind of novel air stripping mentions mud device, including steam line 2, in 1 and of conveyance conduit of inverted "L" shape Positioned at the casing 3 of 1 pipe bent position of conveyance conduit；The water inlet of conveyance conduit 1 is horn-like nozzle 4, and steam line 2 is inserted through casing 3 Enter in conveyance conduit 1, the gas outlet of steam line 2 extends to the water inlet of conveyance conduit 1, and is equipped with and is fixed on steam line The aeration head 5 of 2 gas outlets, aeration head 5 is rounded, and diameter is consistent with the outer diameter of steam line 2, and bottom is additionally provided with 3-8 A solarization air cap, the air inlet of steam line 2 with the aeration pipe blower of oxidation ditch bottom of trench for being connected；1 water outlet of conveyance conduit Plane where locating lower end is equal with liquid level to be processed.

Embodiment 2

As shown in Figure 1-3, a kind of novel air stripping mentions mud device, including steam line 2, in 1 and of conveyance conduit of inverted "L" shape Positioned at the casing 3 of 1 pipe bent position of conveyance conduit；The water inlet of conveyance conduit 1 is horn-like nozzle 4, and steam line 2 is inserted through casing 3 Enter in conveyance conduit 1, the gas outlet of steam line 2 extends to 1 water inlet of conveyance conduit, and is equipped with and is fixed on steam line 2 The aeration head 5 of gas outlet, aeration head 5 are blind plate, and rounded, diameter is consistent with the outer diameter of steam line 2；Steam line 2 On open up 4-8 solarization air cap at away from its gas outlet 8-12cm, the air inlet of steam line 2 is for the aeration with oxidation ditch bottom of trench Pipe blower is connected；Plane where 1 water outlet lower end of conveyance conduit is equal with liquid level to be processed.

The use process of the device: compressed air reaches the water inlet of conveyance conduit 1 through the steam line 2 of above-mentioned apparatus Place, releases through solarization air cap, is sufficiently mixed with the mixed liquor in processing pond, and has certain stirring capacity to mixed liquor, Since the difference in specific gravity of mixing wastewater with air liquid and mixed liquor generates the power risen, move up mixed liquor or sludge along conveyance conduit 1, most Destination is discharged by the water outlet of conveyance conduit 1 eventually.

Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, this field Other modifications or equivalent replacement that those of ordinary skill makes the technical solution of the utility model, it is practical without departing from this The spirit and scope of new technique scheme should all cover in the scope of the claims of the utility model.
