Description

Hard tube vertical suspension aeration system

technical field

The utility model relates to a hard tube vertical suspension aeration system, which is applied in the technical field of sewage treatment.

Background technique

At present, in the sewage treatment process, ozone is generally used to chemically oxidize the components in the sewage, which puts forward higher requirements for the corrosion resistance and ventilation resistance of the aeration device in the sewage aeration tank. The aeration device used in some sewage aeration tanks mainly includes an aeration pipe installed at the bottom of the aeration tank and an aerator installed on the aeration pipe. Due to the aging, damage, blockage of the aeration head or the damage of the pipeline, the aeration resistance in each corridor increases and the aeration is uneven; resulting in insufficient air supply in the pool, which greatly reduces the sewage treatment capacity of the entire aeration system and Pollutant removal capabilities. Moreover, since the entire device is installed on the bottom of the aeration tank with a fixed bottom, it is easy to corrode, and the method of pickling is used for regular cleaning and maintenance to block the aeration head.

Utility model content

In order to solve the problems existing in the prior art, the purpose of the utility model is to provide a hard tube vertical suspension aeration system with small ventilation resistance, high working efficiency and corrosion resistance.

The technical solution adopted by the utility model to achieve the above purpose is a hard tube vertical suspension aeration system, which includes a main air supply pipe installed on the upper part of the aeration tank, and is characterized in that a main pipe is connected to the main air supply pipe, There are several branch pipes connected to the top, and the main pipe and the branch pipes are connected to each other to form a ring air supply pipeline. Several hanging air pipes are installed on each branch pipe. One end of the hanging air pipe is connected with the two branch pipes, and the other end extends into the bottom of the aeration tank. And it is connected with several tubular microporous aerators.

The utility model is further set to:

The hanging air duct is connected to the branch pipe through a flange, and is fastened with a reinforcing plate. A distributor is connected under the hanging air duct, and the tubular microporous aerator is installed on the distributor through a short wire pipe.

Preferably, four tube-type microporous aerators are installed on each hanging air duct.

The above tubular microporous aerator is preferably a polymer tubular microporous aerator.

Beneficial effect analysis of the utility model: the utility model adopts a hard tube vertical suspension aeration system, compared with the original aeration device, it has better air supply volume, ventilation resistance, biochemical effect, clogging resistance, service life, etc. Great improvement, the comparison is as follows:

Detailed ways

As shown in Figure 1 and Figure 2, the utility model includes an air supply main pipe 2 installed in the aeration tank 1, a main pipe 3 is connected to the air supply main pipe 2, and the main pipe 3 is fixed on the pool wall of the aeration tank 1, A branch pipe 4 is connected to the main pipe 3, and the main pipe 3 and the branch pipe 4 are connected to each other to form a ring air supply pipeline. A hanging air pipe 5 is installed on each branch pipe 4, and the number of the branch pipe 4 and the hanging air pipe 5 depends on the aeration The size of the pool 1 and the air supply need to be set accordingly. One end of the suspension air duct 5 is connected to the branch pipe 4 through the flange 13, and is fastened by the reinforcement plate 11 and the reinforcement plate 12. The other end is equipped with a distributor 8, which is connected to the suspension The air pipes 5 are also fastened with reinforcing plates 6, and four air outlets are arranged on the distributor 8, which are respectively connected with four polymer tubular microporous aerators 10 through short wire pipes 7, in order to ensure that the polymer The stability of the tubular microporous aerator 10 is secured by using screws 9 to fasten the polymer tubular microporous aerator 10 on the distributor 8 .

The utility model adopts the vertical suspension of a hard tube for aeration, and extends the polymer tubular microporous aerator 10 into the bottom of the aeration tank 1 through the suspension air tube 5 for aeration. The ventilation resistance is small, which can effectively prevent blockage. , When cleaning, only need to lift up the whole device, simple structure, easy maintenance.
