Abstract
The utility model discloses a self-suction type jet flow aerator which is vertically arranged in an aeration tank, and is connected with a main pipeline through a flange. The self-suction type jet flow aerator comprises a tubular main body, wherein an air chamber is arranged at one end of the tubular main body, the other end of the tubular main body is communicated with a tail pipe, the air chamber is respectively communicated with a nozzle and an air inlet pipe, and the air inlet pipe and the air chamber are arranged above the water level of the aeration tank. A choke, a collapsible pipe and a diffusion pipe which are sequentially connected are arranged inside the tubular main body, the choke is communicated with the air chamber, and the diffusion pipe is communicated with the tail pipe. According to the self-suction type jet flow aerator, wastewater and activated sludge are used as working liquids, a negative pressure generated by high-speed jet of the nozzle is used for sucking air into the air chamber through the air inlet pipe, the sucked air and the working liquids are turbulently fluctuated and mixed in the collapsible pipe, the diffusion pipe and the tail pipe, air, the wastewater and the activated sludge form a homogeneous emulsion to reach an oxygen saturation state and are jetted out from the tail pipe, and the jetted homogeneous emulsion continuously carries out mass transfer in a cyclone and turbulent water body in the aeration tank.
Description
Technical field
The utility model relates to a kind of aerator, is specifically related to a kind of self-priming jet-flow aeration equipment.Belong to the environmental protection equipment field.
Background technology
Along with the development of environmental protection industry (epi), various oxygenation forms are full of in the middle of market.The rational oxygen replenishing equipment of correct selection becomes one of key point of water treatment project.
But traditional aeration mode has drawbacks such as energy consumption height, maintenance complexity.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, a kind of self-priming jet-flow aeration equipment being provided.This aerator is applicable to waste water control, has advantages such as oxygenation capacity is strong, coefficient of oxygen utilization is high, stable and reliable operation.
For achieving the above object, the utility model adopts following technical proposals:
A kind of self-priming jet-flow aeration equipment, this equipment vertically is installed in the aeration tank, and is connected with main pipe line by flange; It comprises tubular body, and an end of tubular body is provided with air chamber, and the other end is communicated with tail pipe, and described air chamber is communicated with nozzle and inlet pipe respectively, and inlet pipe and air chamber are all more than the water surface of aeration tank.
Described tubular body inside is provided with trunnion, collapsible tube and the diffuser tube that connects successively, and described trunnion is communicated with air chamber, and described diffuser tube is communicated with tail pipe.
Principle of work of the present utility model:
The utility model is a working fluid with waste water and active sludge, the negative pressure that the nozzle high-velocity jet produces sucks air chamber with air through inlet pipe, inhaled air mixes with working fluid turbulent fluctuation in collapsible tube, diffuser tube and tail pipe, air, waste water and active sludge three-phase form homogenizing emulsifying liquid, reach the oxygen saturation state, and, in the aeration tank, proceed effect of mass transmitting in the water body of eddy flow and turbulent fluctuation from the tail pipe ejection.Like this, active sludge both can also can absorb oxygen and organism in self-priming jet-flow aeration equipment in the aeration tank, strengthened effect of mass transmitting greatly, thereby improved the utilization ratio (can reach more than 40%) of oxygen, increased active sludge and absorbed and the organic ability of metabolism.

Principle of work of the present utility model:
The utility model is a working fluid with waste water and active sludge, the negative pressure that nozzle 1 high-velocity jet produces sucks air chamber 3 with air through inlet pipe 2, inhaled air mixes with working fluid turbulent fluctuation in collapsible tube 5, diffuser tube 6 and tail pipe 7, air, waste water and active sludge three-phase form homogenizing emulsifying liquid, reach the oxygen saturation state, and, in the aeration tank, proceed effect of mass transmitting in the water body of eddy flow and turbulent fluctuation from tail pipe 7 ejections.Like this, active sludge both can also can absorb oxygen and organism in self-priming jet-flow aeration equipment in the aeration tank, strengthened effect of mass transmitting greatly, thereby improved the utilization ratio (can reach more than 40%) of oxygen, increased active sludge and absorbed and the organic ability of metabolism.
The test example:
Certain wastewater of starch factory, the water yield are 7000m
3/ d adopts 120 of self-priming jet-flow aeration equipment of the present utility model, the about 1000mg/L of aerobic water inlet cod, water outlet cod＜100mg/L, clearance is about 90%, and oxygen transfer efficiency is 40%.
