Deep well aeration device

Abstract

The invention discloses a deep well aeration device, and belongs to the field of aeration sewage treatment devices. The device is characterized by comprising a treatment tank for accommodating and completing aeration treatment, a deep well outer barrel is vertically arranged on the bottom surface of the treatment tank, a deep well inner barrel is fixedly mounted in the deep well outer barrel, thedeep well inner barrel is positioned on the axis, a water inlet pipe and a sludge pipe are fixedly connected to the top of the deep well inner barrel, an air inlet pipe is further vertically arrangedin the deep well outer barrel, the top end of the air inlet pipe is fixedly connected with an air compressor, the air compressor is mounted at the edge of the treatment tank, the bottom end of the airinlet pipe is fixedly connected with an aeration chamber; the bottom of the aeration chamber is provided with an air injection pipe used for being communicated with the deep well inner barrel, the side wall of the aeration chamber is fixedly connected with a second air supplementing pipe, and the second air supplementing pipe is embedded into the inner wall of the deep well inner barrel. The deepwell aeration device has the advantages of being good in sewage and air mixing effect, good in aeration effect, low in cost and high in economic benefit.

Description

technical field [0001] The invention relates to an aeration sewage treatment device, in particular to a deep well aeration device. Background technique [0002] The Chinese patent with the publication number CN102745803A discloses a deep well aeration device, which includes a deep well body, a top tank, a downcomer and a riser, and is also provided with a degassing tank, which communicates with the top tank, and the top tank is provided with a side Internal circulation channel, the number of side internal circulation channels is ≥ 2, the channel is connected with the riser, the riser is located between the downcomer and the deep well shell, the top of the downcomer is equipped with a blowout preventer, 1 / 2-1 of the downcomer / 3 is equipped with a high-efficiency gas-liquid turbulence device, the downcomer and the deep well casing have a concentric structure, and the deep well casing is a "U"-shaped structure. [0003] This kind of deep well aeration device usually has a wel...

AI Technical Summary

Problems solved by technology

[0003] This kind of deep well aeration device usually has a well depth of about 100 meters. The compressed air is injected into the bottom of the well after being pressurized by an air compressor. However, in the actual use process, the aeration efficiency is low. In order to improve the aeration efficiency , so the selection requirements for air compressors are extremely strict. Air compressors with better performance usually occupy a larger area and increase construction costs. The energy consumption is not conducive to the conservation and utilization of energy, and it also increases the processing cost, and the economic benefit is low
