Gas stripping device and aerated grit chamber

Abstract

The invention discloses a gas stripping device and an aerated grit chamber, and relates to the field of sewage treatment. The device comprises a fan; a flushing pump; two sand outlet pipes, wherein one ends of the two sand outlet pipes are used for being arranged in the aerated grit chamber, monitoring modules are arranged on the sand outlet pipes, and the monitoring modules can monitor the sand outlet state and the transverse stress state of the sand outlet pipes; an air pipe, wherein one end of the air pipe is connected with one end of the sand outlet pipe, the other end of the air pipe is connected with the fan, and a gas control valve is arranged on the air pipe; a flushing pipe, wherein one end of the flushing pipe is connected with one end of the sand outlet pipe, the other end of the flushing pipe is connected with the flushing pump, and a flushing control valve is arranged on the flushing pipe; and a control unit connected with the monitoring module, the gas control valve and the flushing control valve, wherein the gas stripping device adopts the two groups of gas stripping pipelines to operate alternately, the control unit is matched to control the gas control valve, the flushing water pump and the monitoring module, and through transmission and analysis, gas stripping pipeline blockage alarm and automatic dredging are realized, and the equipment maintenance frequency is reduced.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and more specifically relates to an air lift device and an aeration grit chamber. Background technique [0002] At present, submersible sand pumps or relatively simple air lift devices are used in aerated grit chambers to lift the bottom grit to the outside of the tank to complete the solid-liquid separation process, but this device has serious wear and tear on the sand pump and is prone to blockage , and the degree of equipment self-monitoring is low, resulting in frequent equipment maintenance and low work efficiency. Contents of the invention [0003] The object of the present invention is to provide an air lift device and an aeration grit chamber to address the deficiencies in the prior art. The unit controls the gas control valve and the flushing control valve to realize the automatic switching and dredging of the gas lift pipeline, which reduces the frequency of equipment maintenance and ...
