Description
Technical field
The utility model belongs to aeration process field, specifically, relates to a kind of Venturi ejector efficiently.
Background technology
In water treatment field, the shortcoming such as all undesirable and device structure of traditional blast aeration and the oxygen mass transfer coefficients of mechanical aeration, dissolved oxygen speed, mix and blend effect is complicated.Conventional fluidic aerator inspiratory capacity under natural aspiration mode is not enough, and to increase inspiratory capacity be generally increase water pump power and jet aerator quantity, and increase blower equipment, conventional fluidic aerator is all single Venturi ejector, and difference is the large and little of Venturi ejector, when Venturi ejector do larger time, there is gas and water engaging surface is little, can not fully by gas and liquid mixing, bubble generation is large, it is low that bubble smashes degree, affects aeration effect.
Utility model content
For solving above technical problem, the purpose of this utility model is to provide a kind of Venturi ejector efficiently, and multiple inlet pipe is tangentially ventilated, and gas distribution is even, and increase gas and liquid comes into contact area, oxygen-transfer efficiency is high.
The utility model object is achieved in that a kind of Venturi ejector efficiently, its key is: comprise the jet head, cylindrical mixing chamber and the diffuser tube that dock successively, described jet head is horn-like, the miner diameter end of this jet head extend in described cylindrical mixing chamber, the miner diameter end of this jet head is arranged near described cylindrical mixing chamber right-hand member, at least 2 inlet pipe are communicated with in the middle part of described cylindrical mixing chamber, this inlet pipe is tangentially arranged on described cylindrical mixing chamber, and inlet pipe described in each is arranged with the central shaft centrosymmetry of cylindrical mixing chamber.
Adopt said structure, current are entered by jet head, gas enters from inlet pipe, the gas of inlet pipe enters after in cylindrical mixing chamber, mix along spiral inner wall with current, gas distribution is even, gas forms very trickle bubble under the effect of high speed strenuous exercise, add contact area, and then increase inspiratory capacity and OTR, and then increase active sludge Surface Renewal rate and adsorption surface area, thus make oxygen and useless Organic substance in water in the tiny cotton-shaped physical efficiency of active sludge and bubble have abundant Contact-sorption effect, improve aeration effect.
The channel diameter of above-mentioned cylindrical mixing chamber reduces to low order end gradually from inlet pipe junction, and the miner diameter end diameter of described jet head is less than described cylindrical mixing chamber right-hand member porthole diameter.
The miner diameter end diameter of above-mentioned jet head is 20-30mm, and the right-hand member porthole diameter of described cylindrical mixing chamber is 40-80mm, and the vertical range of described jet head miner diameter end and described cylindrical mixing chamber right-hand member porthole is 5-30mm.
Adopting said structure, closes up in right part in the internal passages of cylindrical mixing chamber, is compressed by air-flow, increases the severe degree of the motion of air-flow, is convenient to bubble to smash, and increases contact area.
The inwall of above-mentioned inlet pipe and diffuser tube is distributed with the rifle formation of spiral extension, this rifle formation makes air-flow or current carry out helicoidal flow when leaving pipeline.
Adopt said structure, be convenient to further bubble be smashed.
Above-mentioned diffuser tube is horn-like, and the miner diameter end of this diffuser tube docks with described cylindrical mixing chamber.
Adopt said structure, trumpet-shaped diffuser tube can increase aeration surface-area.
The bigger diameter end of above-mentioned jet head is provided with Flange joint dish, and the bigger diameter end port capping of described diffuser tube has stainless (steel) wire.
Adopt said structure, the Flange joint dish of jet head is convenient to install and is connected, and bubble can be smashed by stainless (steel) wire again.
Beneficial effect:
A kind of Venturi ejector efficiently of the utility model, multiple inlet pipe is tangentially ventilated, and gas distribution is even, and increase gas and liquid comes into contact area, oxygen-transfer efficiency is high.
Embodiment
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
Embodiment:
As illustrated in fig. 1 and 2: a kind of Venturi ejector efficiently, by the jet head 1 docked successively, cylindrical mixing chamber 2 and diffuser tube 3 form, described jet head 1 is in horn-like, the miner diameter end of this jet head 1 extend in described cylindrical mixing chamber 2, the miner diameter end of this jet head 1 is arranged near described cylindrical mixing chamber 2 right-hand member, 2 inlet pipe 4 are communicated with in the middle part of described cylindrical mixing chamber 2, the number of certain inlet pipe also can be 3, 4, 5, 6 etc., as long as multiple inlet pipe can be realized evenly ventilate in mixing section, this inlet pipe 4 is tangentially arranged on described cylindrical mixing chamber 2, inlet pipe 4 described in each is arranged with the central shaft centrosymmetry of cylindrical mixing chamber 2.
