Abstract

A high-efficiency jet aerator includes a nozzle, an air mixing chamber, a mixing pipe, and a diffuser pipe. The nozzle is fixedly connected to the air mixing chamber, and the outlet end of the nozzle is installed in the air mixing chamber. A suction pipe is installed on the air mixing chamber. The tube and the diffusion tube are connected as a whole, and the mixing tube is connected to the outlet of the gas mixing chamber. The utility model is characterized in that the outlet of the nozzle is fixedly connected to the secondary efficiency tube. The utility model strengthens the gas-water mixing effect, the airflow crushes thoroughly, improves the oxygenation efficiency, has low power consumption, low operation cost, no noise, simple structure and convenient maintenance.

Description

The high-efficiency jet aeration device

Technical field

The utility model relates to the sewage sludge processing technology field; Be specifically related to a kind of high-efficiency jet aeration device; Can be widely used in river regulation engineering, WWT plant aeration tank, aerated grit chamber; Mixed solution to sewage sludge carries out oxygenation and mixing, and sewage is carried out biochemical treatment or cultures pool oxygenation.

Background technology

The tradition jet aerator is under the high speed rotating of pump impeller, and liquid sprays from nozzle with high speed, when swiftly flowing liquid passes through mixing chamber; Can form vacuum at mixing chamber, suck a large amount of air by gas tube, behind the air admission mixing chamber; Acutely mix with liquid at the trunnion place, form gas liquid mixture, discharge by diffuser tube; Air rises with trickle bubble in water body, in whole process, forms material transfer efficiently.Traditional this jet aerator liquid is directly from the nozzle ejection, and its flow velocity, air water mixed effect and oxygen-transfer efficiency all remain further to be improved.

Summary of the invention

The utility model technical problem to be solved is: to the situation of above-mentioned prior art, and a kind of high-efficiency jet aeration device is provided, strengthens the air water mixed effect, comminution by gas stream is thorough; Oxygen-transfer efficiency is high, and power consumption is low, and working cost is few; Noiseless, simple in structure, easy to maintenance.

The technical scheme that the utility model adopts is: this high-efficiency jet aeration device; Comprise nozzle, mixing chamber, mixing head, diffuser tube, nozzle is connected fixing with mixing chamber, and nozzle exit end is installed in the mixing chamber; Air suction pipe is installed on the mixing chamber; Mixing head is whole for being connected with diffuser tube, and mixing head and mixing chamber exit end connect, and the characteristic of the utility model is to be communicated with secondary synergy pipe at nozzle exit end.

In the technique scheme, described secondary synergy pipe extends in the mixing head always.

In the technique scheme, described secondary synergy pipe front opening, side perforate.

In the technique scheme, described secondary synergy pipe is connected moulding with nozzle-integrated.

Advantageous effect:

(1) jet aerator mixing stirring action is strong, and it is high to have higher oxygenation capacity, coefficient of oxygen utilization and oxygen power transfer efficiency.

(2) simple structure, reliable operation goes slick, and is convenient to regulate, and is difficult for stopping up the easy-maintaining management.

(3) adopt self-priming jet aerator, can cancel gas blower, pollution abates the noise.

(4) in the jet aerator trunnion; Because effusive turbulent fluctuation and energy exchange effect; Formed violent blending phenomenon; Not only accomplish oxygen from the transfer of gas phase to liquid phase in moment; And the working flow of jet-flow aeration is the mixed solution or the aeration tank mixed solution of into water and returned sluge, therefore in mixed solution, promptly carrying out mud (mikrobe)-water (organism)-triangular mass transfer of gas (dissolved oxygen) and biochemical reaction, and this is a quick bio reaction that takes place under given conditions and the combined process of three alternate mass transfers.

(5) improved the activity of mud, the substrate degradation constant is high than other activated sludge process.

(6) construction investment is economized, and floor space is little.

(7) the high-efficiency jet aeration device of employing the utility model, the utilization ratio of oxygen reaches more than 28%.Play the stirring effect during mixing, except that being applicable to conventional actived sludge, also be applicable to the activated sludge process and Combination mud method fully of long high MLSS of mud age.

(8) the theoretical dynamicefficiency of the high-efficiency jet aeration device of the utility model is high, can reach 3.0kg/kWh, compares with general jet aerator, and energy consumption is low, can reduce more than 30% at most.
