进口潜水射流曝气机-进口潜水曝气机-德国KAYSEN泵业

GERMANY KAYSEN PUMP CO .,LTD

深水自吸式自耦式潜水射流曝气机是向曝气池内曝气的废水装置,是废水活性污泥法生物处理系统曝气装置的一种类型。由水泵将泥、水混合液打入射流曝气器喷嘴,并高速喷出,在射流曝气器内,氧转移过程的实现是在这个射流曝气器喷嘴周围使压缩空气(或空气直接吸入)与泥水混合液混合并在吼管中强烈搅动,气泡被粉碎成雾状,继而在扩散管中由于速头变成压头,微细气泡进一步被压缩,氧即迅速转移到混合液,从而强化了氧的转移过程,氧转移效率可提高到30-35%以上
 

主要特点:

自重定位,安装方便,可在不中断工艺运行的状态下自由布置
设计结构紧凑,利用自吸功能无需外接气源;    
主机潜水作业减少占地面积,噪音小;    
可直接在氧化塘中使用,节省基建成本;    
独立移动的曝气装置,曝气时兼有搅拌功能;    
底盘可根据用户要求作特殊设计。


主要优点:

采用潜水电机密封技术的水下电机;   

叶轮与电机直联,结构简单,效率高,寿命长;    

可加网状进水口,避免异物进入机体引起不必要的破坏;   

可通过进气阀调节进气量;    

除电机外,其它部件材质有不锈钢、碳钢和铸铁供选择。


主要应用:
潜水射流式曝气机用于各种污水处理工程中生化处理工艺的曝气池、曝气沉砂池、预曝气池、好氧硝化池曝气充氧混合及养殖塘增氧。

潜水射流曝气机选型
建议从五个方面加以考虑,既液体输送量、扬程、液体性质、管路布置以及操作运转条件等。
1、流量是选射流曝气机的重要性能数据之一,它直接关系到整个装置的的生产能力和输送能力。如设计工艺能算出离心曝气机正常、较小、较大三种流量。选择离心曝气机时,以理想流量为依据,兼顾正常流量,在没有理想流量时,通常可取正常流量的1.1倍作为理想流量。    
2、扬程是选射流曝气机的又一重要性能数据,一般要用放大5%—10%余量后扬程来选型。   
3、液体性质,包括液体介质名称,物理性质,化学性质和其它性质,物理性质有温度c、密度d、粘度u,介质中固体颗粒直径和气体的含量等,这涉及到系统的扬程,有效气蚀余量计算和合适泵的类型:化学性质,主要指液体介质的化学腐蚀性和毒性,是选用泵材料和选用那一种轴封型式的重要依据。    
4、管路布置条件指的是送液高度送液距离送液走向,吸如侧较低液面,排出侧较高液面等一些数据和管道规格及其长度、材料、管件规格、数量等,以便进行系梳扬程计算和汽蚀余量的校核。   
 5、操作条件的内容很多,如液体的操作T饱和蒸汽力P、吸入侧压力PS(*)、排出侧容器压力PZ、海拔高度、环境温度操作是间隙的还是连续的、泵的位置是固定的还是可移的。 


Submersible jet aerator

Submersible aerator

Submersible centrifugal aerator



The deepwater self-priming self-coupled submersible jet aerator is a type of wastewater device that aerates the aeration tank and is a type of aeration device for the biological wastewater treatment system of the wastewater activated sludge process. The mud and water mixture is pumped into the nozzle of the incident aerator by a water pump, and is sprayed at a high speed. In the jet aerator, the oxygen transfer process is realized by directly inhaling compressed air (or air) around the nozzle of the jet aerator. Mixing with the muddy water mixture and vigorously stirring in the manifold, the bubbles are pulverized into a mist, and then in the diffusion tube, the tip becomes a pressure head, the fine bubbles are further compressed, and the oxygen is quickly transferred to the mixture, thereby strengthening Oxygen transfer process, oxygen transfer efficiency can be increased to 30-35% or more

 


main feature:


● Self-repositioning, easy to install, free to arrange without interrupting the process operation

●The design is compact, and the self-priming function does not require an external air source;

●The host diving operation reduces the floor space and the noise is small;

● It can be used directly in oxidation ponds to save infrastructure costs;

● Independently moving aeration device, which has a stirring function when aeration;

●The chassis can be specially designed according to user requirements.



The main advantage:


●Underwater motor with submersible motor sealing technology;


●The impeller and the motor are directly connected, the structure is simple, the efficiency is high, and the service life is long;


●It can be added with a mesh inlet to prevent foreign matter from entering the body and causing unnecessary damage;


● The intake air amount can be adjusted through the intake valve;


● In addition to the motor, other parts are available in stainless steel, carbon steel and cast iron.



main application:

The submersible jet aerator is used in the aeration tank, aerated grit chamber, pre-aeration tank, aerobic nitrification tank aeration and oxygenation mixing and aquaculture pond oxygenation in various sewage treatment projects.


Submersible jet aerator selection

It is recommended to consider five aspects, such as liquid delivery volume, head, liquid properties, piping layout, and operating conditions.

1. Flow rate is one of the important performance data of the selected jet aerator, which is directly related to the production capacity and conveying capacity of the entire device. For example, the design process can calculate the normal, small and large flow rates of the centrifugal aerator. When a centrifugal aerator is selected, the normal flow rate is based on the ideal flow rate. When there is no ideal flow rate, 1.1 times the normal flow rate can be taken as the ideal flow rate.

2. The lift is another important performance data of the jet aerator. Generally, it should be selected by amplifying the lift by 5%-10%.

3, liquid properties, including liquid media name, physical properties, chemical properties and other properties, physical properties are temperature c, density d, viscosity u, solid particle diameter and gas content in the medium, etc., which involves the lift of the system, effective Calculation of cavitation allowance and type of suitable pump: chemical properties, mainly refers to the chemical corrosiveness and toxicity of the liquid medium, which is an important basis for selecting the pump material and selecting the type of shaft seal.

4. Pipeline layout conditions refer to the liquid feeding height, the liquid feeding distance, the lower liquid level, the higher liquid level on the discharge side, and other data and pipe specifications and their length, materials, pipe fittings specifications, quantity, etc. In order to carry out the calculation of the combing process and the checking of the NPSH.

 5. There are many operating conditions, such as liquid operation T saturated steam force P, suction side pressure PS (absolute), discharge side container pressure PZ, altitude, ambient temperature operation is gap or continuous, pump position is fixed Still removable.
