Description
Technical field
The utility model relates to a kind of jet aerator, is specifically related to a kind of PSP jet-flow aeration system.
Background technology
Aerator classification in the market has following several: blast aeration, surface aeration, under water aeration, oxygen aeration etc. are several.
(1) blast aeration equipment is made up of air pressurized equipment, piping system and air-diffuser.Air pressurized equipment generally selects gas blower.Air diffuser has the first-class various ways of diffuser plate, vertical tube, perforated pipe, micro-pore aeration.
(2) oxygen aerator is made up of oxygen, oxygen therapy and oxygenate apparatus etc.
(3) surface aeration equipment, Main Function is that the oxygen in air is dissolved in water.Aerator leads to a leap when water surface rotates, and a large amount of water droplet and sheet-like water shield are thrown in the air, and water fully contacts with air, makes oxygen dissolve in water body very soon.While oxygenation, under the plug-flow effect that aerator rotates, water body few for pond bottom oxygen level is promoted upwards circulation, continuous oxygenation.
(4) failure of underwater aeration equipment is filled with air at water bottom or middle level, mixes with water body is full and uniform, and the gas phase completing oxygen shifts to liquid phase.
Above four class oxygenic aeration equipment, respectively have relative merits.Blast aeration coefficient of oxygen utilization is higher, but there is micro porous aeration head and easily block, break, and rubber diaphragm is easily aging in sewage, needs often to change (3 ~ 5 years), and replacement charge is larger.Oxygen aeration is still rare in China, abroad applies to some extent, can save initial cost, but operating cost is higher.Surface aerating machine is applicable to the technique of the needs plug-flows such as oxidation ditch, though anhydrous lower Awaiting Parts coefficient of oxygen utilization is not high, and drive mechanism often needs repairing, and energy consumption is larger.Aeration is without the need to blower fan oxygen supply under water, but efficiency is lower, is not suitable for large-scale wastewater treatment plant and uses.What current engineering was conventional has blast aeration equipment and surface aeration equipment.
Summary of the invention

As optimization, described inner nozzle and outer nozzle all more and more less towards its nozzle direction internal diameter.
Principle of work: submersible pump water outlet is by jet aerator nozzle, along with inner nozzle nozzle diameter diminishes, liquid is ejected through the hybrid chamber between inner nozzle and outer nozzle with high speed, hybrid chamber is made to form vacuum, large quantity of air is sucked by oxygen supply blower fan, the air sucked is split into a large amount of extremely small bubble under Water Jet Impact, mixed solution is formed by reduced velocity flow during hybrid chamber with water, pressure strengthens, form powerful injection stream to spray from outer nozzle, the effect such as aeration, mix and blend is played to mixed solution.Because bubble is after repeatedly cutting, mixing, form countless tiny bubbles, surface-area is very large, so add coefficient of oxygen utilization, bubble diameter is little simultaneously, and track route is " L " type, lift velocity is slow, thus add gas-liquid contact time, impel gas-to-liquid contact abundant, there is efficient oxygenation mass transfer and agitating function.
Mix and blend principle: when cut-out pressure air feed, in water-supply pipe, sewage is by inner nozzle ejection at a high speed, around low-velocity liquid is strongly involved in and is carried out momentum exchange, be involved in part and add again injection main flow, jet flow section constantly expands, and carrying flow constantly increases, and flow velocity progressively reduces, go round and begin again, finally realize the anaerobic mix and blend to pending water.
Beneficial effect: the utility model compared with prior art:
1, coefficient of oxygen utilization is high, jet aerator constantly cut air with swiftly flowing liquid, the air entered in hybrid chamber and water are fully mixed rear jet in pond, except diffuser efficiency is high in a liquid with the small bubbles in air, the turbulent state of jet aerator is that gas-to-liquid contact face is constantly updated, be conducive to the transmission of oxygen, simultaneously due to negative pressure that fluidic vectoring thrust is certain, jet aerator fitting depth can be greater than the specified blast of blower fan, the intensification of Aerobic Pond, too increase the utilization ratio of oxygen, coefficient of oxygen utilization can reach more than 25%.
2, suitability, is suitable for various water quality, and PSP jet aerator manually can control separately between oxygen supply and stirring.This makes operative employee can regulate the size of air capacity as required, and maintains stirring and can pass through circulation fluid.In conjunction with manual and automatic DO instrument control system, energy consumption can be saved when underload.It is ideal for maintaining stirring to the biochemical system of aerobic/anaerobic alternate cycles by stopping air feed, can natural birth caliche and denitrification process by processing set-up.
3, simple and convenient operation and maintenance, jet aerator utilizes common auxiliary facility completely, such as impeller pump and centrifugal blower, and all moving-members are all located at convenient for maintaining outside pond.The heavy caliber jet orifice of jet aerator and the jet speed of more than 10m/S effectively can prevent blocking, wear resistant corrosion resistant material can ensure life-time service and need not safeguard, ejector does not need to cover installation at the bottom of whole pond simultaneously, can save a lot of settling time and installation costs.
4, energy consumption is low, and jet aerator can need according to Aerobic Pond flooding quantity and water quality the size regulating air capacity and flooding quantity, can save energy consumption when underload.
5, long service life, adopt specific glass strengthening material, protection against corrosion, anti-aging, abrasion resistance properties is superior, work-ing life overlength, for routine is exposed to the sun 5 ~ 10 times of apparatus.
