By adopting the scheme, the gas outlet of the aeration device passes through the included angle between the branch pipe and the main pipe, the direction of the gas flow is changed, then the gas flow passes through the bent section at the end part of the branch pipe, the gas flow changes the direction again, and the gas enters the oxidation tank in a spiral shape due to the inertia, so that the sediment in the oxidation tank can be dispersed, and the blockage of the orifice of the aeration pipe is avoided; on the other hand, the gas rises spirally in the oxidation pond, the walking distance is increased by at least several times, and the contact time with the oxide to be oxidized in the oxidation pond is greatly increased, so that the oxidation effect is greatly improved.

Description

End of aeration pipe

Technical Field

The utility model belongs to the field of wastewater treatment devices, concretely relates to aeration pipe end.

Background

Aeration oxidation is an important means for wastewater treatment, and aims to transfer oxygen in air into water through aeration, transfer the oxygen from a gas phase to a liquid phase through mass transfer, thereby converting a reduced valence state in the liquid phase into a stable valence state, and simultaneously blow off unwanted gases and volatile substances in water from the liquid.

The design of aeration pipe is crucial to aeration oxidation, and many aeration branch pipes of configuration are gone up for the main trachea to traditional oxidation aeration pipe mostly, arrange a series of aeration holes on the branch pipe, because aeration hole aperture is less, the deposit in the aeration tank leads to aeration hole to block up easily, influences aeration efficiency.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an aeration pipe end not only can effectively prevent that the aeration hole from blockking up, can also increase substantially aeration oxidation effect.

In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides an aeration pipe end, includes the branch pipe of being connected with the main pipe that aeration equipment's outlet duct is connected and being responsible for the end connection, is the contained angle formula between branch pipe and the main pipe and arranges, and the free end of branch pipe extends and buckles to the direction of keeping away from the main pipe.

By adopting the scheme, the gas outlet of the aeration device passes through the included angle between the branch pipe and the main pipe, the direction of the gas flow is changed, then the gas flow passes through the bent section at the end part of the branch pipe, the gas flow changes the direction again, and the gas enters the oxidation tank in a spiral shape due to the inertia, so that the sediment in the oxidation tank can be dispersed, and the blockage of the orifice of the aeration pipe is avoided; on the other hand, the gas rises spirally in the oxidation pond, the walking distance is increased by at least several times, and the contact time with the oxide to be oxidized in the oxidation pond is greatly increased, so that the oxidation effect is greatly improved.

Detailed Description

The technical solution of the present invention will be further described with reference to the accompanying drawings.

An aeration pipe end comprises a main pipe 10 connected with an air outlet pipe of an aeration device and a branch pipe 20 connected with the end part of the main pipe, wherein the branch pipe 20 and the main pipe 10 are arranged in an included angle mode, and the free end of the branch pipe 20 extends and bends towards the direction far away from the main pipe 10.

Preferably, the number of the branch pipes 20 is 2 to 6, and more preferably 4, and the branch pipes 20 are uniformly distributed in the circumferential direction at the end of the main pipe 10. As shown in fig. 2, four branch pipes 20 may be arranged in a star shape (four branch pipes are connected at one end and extend away from the intersection point, preferably in the same plane), and the end of the main pipe 10 is connected at the intersection point of the four branch pipes, which results in the structure shown in fig. 2. The structure can more uniformly convey gas to the aeration device, and the aeration oxidation efficiency is improved.

The bending section of the free end of the branch pipe 20 is an arc pipe, and the bending directions of all the branch pipes are consistent. As shown in FIG. 2, the branch pipe 20 comprises a straight pipe section connected with the end of the main pipe 10 and an arc-shaped pipe section far away from the main pipe 10, and during aeration operation, the arc-shaped pipe section of the branch pipe 20 can provide a rotating initial state for the compressed gas, so that not only can the deposits in the oxidation pond be more effectively dispersed, but also the spiral time and spiral stroke of the gas in the oxidation pond can be further increased, and the oxidation effect can be maximally improved.

The branch pipes 20 are generally perpendicular to the main pipe 10 (i.e. the main pipe 10 is substantially perpendicular to the plane of the star formed by the branch pipes), and the bent sections of the branch pipes 20 are bent in the horizontal direction when the aeration pipe is in use. The vertical direction is not necessarily absolute in mathematical sense, and the main pipe 10 extends vertically downwards from the upper part of the oxidation pond, so that the compressed air can be in a spiral rising state after entering the oxidation pond as long as the plane of the branch pipe 20 is approximately horizontal.
