Analysis The Aeration Device Of The Product Features And Classification Of Contrast

HC Valve Network: Oxygenation device efficiency and power efficiency than ordinary microporous aeration equipment has increased, and maintenance is simple and can not affect the normal running (off the water, do not stop gas supply) in the case, for maintenance, replacement of damaged exposed gas devices, practical and reliable.



Specifications: 65 Technical parameters: depth: 4.5m; service area: 2m2 / m; ventilation: 8m/mh; oxygen utilization: 30.36%; power efficiency: 6.24kgO2/kw.h; oxygen supply: 0.68kgO2 / h ; resistance loss: 3600pa; stomatal density: 14000 ~ 15000 / m; travel bubble diameter: 0.5 ~ 5mm.



Microporous membrane aerator Aeration bubble diameter of the device is small, gas-liquid interface of small diameter, large gas-liquid interfacial area, bubble spread evenly, will not produce holes to plug, corrosion resistance, by the Shanghai Tongji Institute of Environment Project College and North China Municipal Engineering Design Institute to conduct testing of water and sewage oxygenation, and by more than 50 years, with favorable results users (compared with conventional products fixed spiral aerators, diffusers and perforated diffuser tube diffusers reduce energy consumption 40%, or increase the treatment capacity 40%). Particularly in urban sewage and large factories, old and new aeration tank expansion and transformation, and the aeration tank can be intermittent.



Of rocker porous aerator aerator and dynamic contrast In addition to the above stated



bubble diameter, oxygen utilization, is easy to plug and other differences, the two have several different points:



Installation Arm movable micropore aerator for the installation, when the aeration device to replace or repair, the elevator will be available from water aerator ? Out construction in the pond for maintenance, without affecting the other aeration devices the same pool of work, without stopping pool water, low maintenance cost, less work.



Dynamic aerator fixed installation, once? After installation is complete, it can not move, if a particular aeration tank needs repair, you must stop the operation of the pool, and the pool of sewage and sludge and other debris removed, before the construction, maintenance costs are relatively high.



Durability Rocker arm failure microporous diffusers have the following three kinds of forms: rusty steel cloth trachea resulting from iron oxide and water and air in the debris will cause aeration tube plugging, aeration air distribution pipe uneven, so that aeration tube jitter caused by fatigue damage; aeration pipe installed in the pipe joints, in the aeration pipe jitter and the dual effect of water erosion, pipe joints easily break from the roots, but also cause corrosion of sewage gas wall cloth thinning perforation; activities of joint long-term underwater rocker soaked in water, rust, etc. may be because the original? Therefore can not rotate, making aerator can not raise to the surface normal. These three kinds of failure modes, by? Through the application of new technologies in recent years has been? Greatly improved, making the life of aerator up to 5 years.



Dynamic failure mode of the aerator are: fatigue or corrosion, as the original? Because, first of all parts of aeration (such as a round shield, rotating mixing barrel, rotary mixed ring, etc.) broken or loose connections, resulting in the dissolution or loss of aeration head; with tracheal rupture; with the general use of UPVC pipe, etc. non-metallic pipe, tube and pipe, tube and pipe fittings and more glue adhesion, once bonding is not strong, easy to fall off and leak from the adhesion Department. These three kinds of failure modes can generally reasonable selection, the correct selection, strict quality control and other methods to avoid. Therefore, this aerator life is longer, up to 8 to 10 years.



Rocker microporous diffusers because the oxygen utilization is high, and easy maintenance, more often used in heavy production load, effluent water quality of a biochemical system than the poor; fixed dynamic aeration device is because oxygen utilization rate lower, but the long term conservation, maintenance difficulties, but the characteristics of long life, low load of general application in the production of sewage water good secondary biochemical system.
