Description

Technical Field

[0001] The utility model relates to the field of sewage treatment devices, in particular to a device for desilting a microporous tube aerator. Background Art

[0002] The tubular aerator is an oxygenating equipment used in urban sewage and organic industrial wastewater treatment systems. The tubular aerator has good chemical stability, does not contain plasticizers, can maintain elasticity for a long time, is acid and alkali resistant, does not harden, does not become brittle, and does not age. The bubble diameter of the product is small, which can not only maintain a high oxygen conversion rate, but also achieve the effect of mixing and stirring.

[0003] The prior art includes a utility model with a publication number of CN2729057Y. The utility model relates to the field of water treatment technology, specifically a tubular microporous aerator with horizontal setting and uniform aeration, characterized in that a flexible connecting pipe is provided between the distribution pipe section and the rigid microporous aeration pipe. Thus, the axial connection of the tubular microporous aerator is changed from a rigid connection to a flexible connection, which not only ensures the horizontal arrangement of the aeration pipe and achieves uniform aeration, greatly improving the aeration performance of the tubular aerator; but also effectively eliminates vibration (shaking) during aeration, which is conducive to extending the service life and reducing overhaul and maintenance, thereby overcoming the shortcomings of the prior art that have not been overcome for a long time. The fast adjustment of the fixed bracket allows the high and low adjustments to be achieved quickly and efficiently during installation, greatly reducing the installation workload and saving more than about 1 / 3 of the installation time. The utility model structure can be used for various tubular microporous aeration, such as rubber diaphragm tubular aerator, ceramic tubular aerator, microporous polymer tubular aerator, etc. However, tubular microporous aerator is prone to blockage, damage, sludge deposition and other problems during operation. As a result, after a certain number of years of use, the wind pressure and energy consumption will increase due to scaling and blockage, and the oxygen utilization rate will drop sharply after damage, which has become a major problem in the daily operation and management of sewage treatment plants using tubular microporous aerators.

[0004] In order to solve the problems of tubular microporous aerators being prone to blockage, breakage, sludge deposition, etc. during operation, which result in increased wind pressure and energy consumption due to scaling and blockage after a certain number of years of use, and a sudden drop in oxygen utilization rate after damage, the existing technology adopts a method of replacing the tubular microporous aerator, but this increases the maintenance burden and cost of the equipment, which in turn leads to the problem of inconvenience in using the equipment.

A device for desilting microporous tubular aerators is proposed.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a device for desilting a microporous tubular aerator, comprising a first microporous tubular aerator and a protective assembly, a second microporous tubular aerator is arranged on one side of the first microporous tubular aerator, a third microporous tubular aerator is arranged on one side of the second microporous tubular aerator, a connecting piece is installed on the surface of the first microporous tubular aerator, the second microporous tubular aerator and the third microporous tubular aerator are respectively installed on both sides of the connecting piece, a first air washing pipe is arranged on the surface of the first microporous tubular aerator, a second air washing pipe is arranged on the side of the first microporous tubular aerator close to the first air washing pipe, and a 1mm air washing hole on the air washing pipe is used to perform high-frequency flushing on the surface blockages of the first microporous tubular aerator, the second microporous tubular aerator and the third microporous tubular aerator, so that the blockages on the surface of the tubular aerator can be quickly and effectively flushed away.

The air wash holes facilitate cleaning of the aerator surface, reduce the difficulty of equipment maintenance, facilitate use, and improve the usability of the equipment.

[0009] Preferably, the diameter of the air washing holes on one side of the first air washing pipeline and the second air washing pipeline is 1 mm.

[0010] Preferably, there are six first air washing pipes and six second air washing pipes, all of which are arranged on the upper surfaces of the first microporous tubular aerator, the second microporous tubular aerator and the third microporous tubular aerator.
