Abstract
The utility model provides a high efficient fluidic aeration device, which is composed of a high pressure nozzle, an air suction cavity, an air imbibing tube and an eddy-mixing cavity. The air suction cavity and the eddy-mixing cavity are arranged as a siphon shaped whole structure according to a certain angle, the high pressure nozzle is arranged at the end part of the air suction cavity, the air imbibing tube is arranged at the position of the high pressure nozzle of air suction cavity, and the inner wall of the eddy-mixing cavity is arranged with a flinching flow device. Compared with the prior art, the high efficient fluidic aeration device of the utility model has the advantages of simple structure, convenient usage, high efficiency of oxygen transfer, energy consumption saving, no gas-liquid blockage problem and so on, and is in particular suitable for an oxidation ditch, a SBR (sequential batch type biochemical reactor) and other activated sludge systems. The utility model has very good popularization and application values.
Description
1, technical field
The utility model relates to a kind of oxygenation aerating apparatus, specifically a kind of high-efficiency jet flow aeration device.
2, technical background
Aerating apparatus is the key equipment of sewage biochemical treatment, and its performance quality directly has influence on treatment effect and operation energy consumption.Aerating apparatus commonly used in the prior art has two classes: a class is the blast aeration device, divide macropore aerating apparatus, mesopore aerating apparatus and microporous aeration device again, commonly used is a kind of at last, this aerating apparatus oxygen transfer efficiency is higher, but breaking of the obstruction of its system and rubber diaphragm is puzzlement people's a difficult problem always, after the damage, must keep in repair the whole aeration tanks of stopping production emptying, cost is very high; Another kind of is surface aeration equipment, utilize impeller, the blade of different shape, impact the water surface when relying on rotation and increase the gas-to-liquid contact area to reach the oxygenation purpose, the advantage of this type of aerating apparatus is, equipment is installed in more than the water surface of pond, mostly is metal or engineering plastics and makes, and is reliable, be convenient to maintenance, but its power consumption is higher, and dynamic efficiency only reaches 1.8kgO
2About/kwh, and temperature influence is very big, again because of requiring the depth of water more shallow, makes floor space very big, only is used at present in the middle or small sewage treatment to use to some extent.
3, summary of the invention
The purpose of this utility model is shortcoming and the deficiency that overcomes above two kinds of aerating apparatuss commonly used, provide a kind of easy to use, oxygen transfer efficiency is high, be difficult for stopping up, the high-efficiency jet flow aeration device of easy care.
A kind of high-efficiency jet flow aeration device of the present utility model is the negative pressure that produces in suction muffler when utilizing high pressure spray nozzle to spray, and in the air suction chamber, the air water mixed solution enters the eddy current hybrid chamber then.Scratch the stream device because of being provided with, when the air water mixed solution is flowed through herein, can produce high-speed eddy at this at eddy current hybrid chamber inwall, blending, air is divided into countless micro-bubbles and pressurized water sprays in the lump.The micro-bubble of Chan Shenging has just improved the contact area of gas-liquid two-phase like this, has reached the purpose of efficient oxygenation.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of high-efficiency jet flow aeration device, constitute by high pressure spray nozzle, suction muffler, air intake pipe, eddy current hybrid chamber, suction muffler and eddy current hybrid chamber are set to the one-piece construction of syphon shape at a certain angle, high pressure spray nozzle is arranged on the end of suction muffler, air intake pipe is arranged on the high pressure spray nozzle place of suction muffler, and eddy current hybrid chamber inwall is provided with scratches the stream device.
Eddy current hybrid chamber inwall is set, and to scratch the stream device can be sheet, groove shape or spirrillum.
A kind of high-efficiency jet flow aeration device of the present utility model is compared outstanding beneficial effect with prior art:
(1) because the micro-bubble that produces in the Liquid Flow process has improved the contact area of gas-liquid two-phase, so the oxygen transfer efficiency height;
(2) air capacity can flexible and do not influence biochemistry pool and mix the effect that stirs, and in addition, because the handiness that this aerating apparatus tolerance is regulated, it also is particularly suitable at anoxic, good oxygen condition downward modulation joint oxygen-supplying amount to save energy consumption;
(3) be suitable for the depth of water and be generally 6-9m, can reach 14m, can save floor space in a large number;
(4) the high speed current have a large amount of kinetic energy, can realize the purpose of directed plug-flow and stirring, to satisfy the needs of different biochemical process;
(5), need not to add air filter to the blower fan wide adaptability;
(6) this device no-rotary part is cast structure, and there is not the gas-liquid blockage problem in the structure uniqueness.
4, description of drawings
Accompanying drawing 1 is a kind of structural representation of high-efficiency jet flow aeration device.
5, embodiment
Explain below with reference to Figure of description a kind of high-efficiency jet flow aeration device of the present utility model being done.
A kind of high-efficiency jet flow aeration device of the present utility model, its structure is to be made of high pressure spray nozzle 1, suction muffler 2, air intake pipe 3, eddy current hybrid chamber 4, suction muffler 2 and eddy current hybrid chamber 4 are set to the one-piece construction of syphon shape at a certain angle, high pressure spray nozzle 1 is arranged on the end of suction muffler 2, air intake pipe 3 is arranged on high pressure spray nozzle 1 place of suction muffler 2, and eddy current hybrid chamber 4 inwalls are provided with scratches stream device 5.Scratching stream device 5 can be sheet, groove shape or spirrillum.
A kind of high-efficiency jet flow aeration device of the present utility model, its processing and fabricating is very simple and convenient, gets final product with the processing of universal machine working method shown in the by specification accompanying drawing 1.Can utilize submersible pump or vertical pump to realize easily for pressurized water, can be installed in the pond and also can be loaded on outside the pond, all adopt the domestic standard product.
Except that the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
