AI Technical Summary

Technical Problem

Traditional aeration devices lack an effective gas filtration structure, which allows impurities in the gas to enter the sewage, clogging the holes, resulting in uneven aeration, large bubbles with small contact areas, and insufficient reaction, thus affecting the sewage treatment effect.

Method used

Design a porous pipeline device for sewage aeration, including a decontamination mechanism and an auxiliary mechanism. The device filters gas through a coarse filter plate, a dense filter plate, a branch pipe and a filter screen. A conical hood prevents impurities from accumulating. An asynchronous motor and a gear system are used to control the gas residence and discharge, achieving flexible control.

Benefits of technology

It improves the gas-liquid mixing effect, enhances the quality and efficiency of wastewater treatment, ensures stable operation of the device, avoids clogging, and improves aeration efficiency and wastewater purification effect.

Abstract

The utility model relates to the technical field of pipeline devices, and discloses a porous pipeline device for sewage aeration, which comprises a sewage pool, a decontamination mechanism is arranged on the sewage pool, and the decontamination mechanism comprises an air inlet pipe. According to the porous pipeline device for sewage aeration, in order to improve the filtering effect on aeration gas, the decontamination mechanism is arranged, after the gas enters the gas collecting box from the gas inlet pipe, a coarse filter plate and a compact filter plate are matched for further fine filtration, and the distribution density of exhaust ports and the gas exhaust area are increased by arranging a plurality of groups of branch gas pipes; meanwhile, the filter screen enables gas to become a plurality of small bubbles, the gas is in contact with sewage in a larger range and at more angles, so that the gas-liquid mixing effect is improved, and due to the conical design of the conical cover, impurities in water are difficult to adhere and accumulate when approaching the top end of the branch gas pipe and can slide down along the inclined plane under the action of water flow; and stable operation of the device is ensured.
