Lifting type aerating system

Abstract

The invention discloses a lifting type aerating system which comprises an aerating unit, a lifting unit and a weight unit. The aerating unit comprises a gas distribution pipeline, and a gas inlet pipe, a water discharge pipe and an aerator are arranged on the gas distribution pipeline. The lifting unit comprises a supporting frame and a guide rail, wherein the supporting frame is arranged at the bottom of the gas distribution pipeline, the guide rail is fixed at the bottom of a pool and extends from the bottom of the pool to the surface of the pool, and a pulley embedded in the guide rail is arranged on the supporting frame. The weight unit comprises a weight pipeline arranged at the bottom of the supporting frame, and a water inlet pipe, a water discharge pipe, a gas inlet pipe and a gasdischarge pipe are arranged on the weight pipeline. The lifting type aerating system has reasonable structure, convenient use and low maintenance cost and can be widely applied to swage treatment.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a lifting aeration system. Background technique [0002] The aerator system is an important and commonly used equipment in sewage treatment plants. It plays an important role in oxygen supply, mass transfer, stirring and mixing in the water treatment process. Its oxygen supply efficiency, installation method, maintenance Conditions are directly related to the treatment effect and operating cost of the entire water treatment system; usually, the aerator system adopts a fixed installation method at the bottom of the underwater pool. Since the aerator system works in the harsh environment of sewage for a long time, When there is a problem with some parts in the system, it is always necessary to drain all the water in the pool to carry out partial maintenance. After the maintenance, the water needs to be re-drained and the bacteria culture needs to be carried out, which will take a certa...

[0002] The aerator system is an important and commonly used equipment in sewage treatment plants. It plays an important role in oxygen supply, mass transfer, stirring and mixing in the water treatment process. Its oxygen supply efficiency, installation method, maintenance Conditions are directly related to the treatment effect and operating cost of the entire water treatment system; usually, the aerator system adopts a fixed installation method at the bottom of the underwater pool. Since the aerator system works in the harsh environment of sewage for a long time, When there is a problem with some parts in the system, it is always necessary to drain all the water in the pool to carry out partial maintenance. After the maintenance, the water needs to be re-drained and the bacteria culture needs to be carried out, which will take a certain amount of time and increase material consumption; This not only affects the timely maintenance, but also affects the normal operation and treatment effect of the sewage treatment system, and consumes a lot of manpower and material resources; and when encountering large sewage treatment plants, they cannot be repaired and reinstalled when they cannot release water. It is extremely inconvenient; at present, although some aeration systems can use some equipment to provide external force to lift them out of the water for maintenance, the operation is more complicated, the maintenance cost is higher, and the use is also subject to various limitations. Not ideal, it is necessary to make improvements in view of the above shortcomings
