How to select sewage aeration fan - sewage aeration roots blower?

Selection principle and application of aeration fan sewage aeration roots blower

(Aeration fan) Model selection of sewage aeration roots blower:

Aeration fan is the abbreviation of sewage aeration roots blower, which is widely used in the sewage treatment of environmental protection industry. Some customers directly call it aeration fan, others call it sewage aeration fan, as well as sewage aeration roots blower and sewage aeration roots blower. No matter which is called, it is the same. It is a kind of Roots blower. In the selection of aeration fan, we usually select the fan according to the air volume and pressure, but we should pay attention to the fact that we try to select the fan with low speed, because too high speed will lead to serious wear of the machine, which will greatly increase the wear of roots blower, thus reducing the life of roots blower

When the same model can meet the actual working conditions, try to choose low speed.

(Aeration fan) Working principle of sewage aeration roots blower:

The working principle of the roots blower for sewage aeration is to connect a pipe at the outlet of the roots blower to the bottom of the sewage treatment pool, and then force the air to the bottom of the sewage pool for aeration. The bubbles formed at the bottom of the water rise due to the buoyancy of the air. In the process of rising, they fully contact and integrate with the water body, so as to increase the dissolved oxygen in the water body

In this way, the microbial active substances in the sewage treatment pool can fully contact with oxygen to react, and then filter, so as to achieve the purpose of decontamination. The main function of Roots blower in sewage treatment aeration is a good annular ecological environment in the sewage biological treatment system.

Advantages of (aeration fan) sewage aeration roots blower:

The aeration fan for sewage treatment of open air machinery is made of high-quality impeller and body. The impeller is dynamically balanced and the casing is sealed. It has the advantages of strong pressure, sufficient wind, stable operation and long service life. There are many product cases. You can come to the factory to investigate and order, open air machinery, and reliable Lyrotz fan suppliers.

① High pressure: sufficient pressure can be generated;

② Adequate aeration: the aeration process is the transfer process of molecular weight between gas and liquid. To make the gas fully diffuse and contact in the liquid and prevent the sinking of suspended solids in the liquid, the aeration fan must be able to generate enough pressure to make oxygen fully stir and dissolve in the liquid; ③ Simple maintenance: maintenance free, and its wear parts are only two

The bearing, within the warranty period, basically does not need maintenance. Note (The aeration fan should not be short of oil during use. Generally, the machine has no problems, and our customers usually have no problems after five or six years of use).

(Aeration fan) Purpose of sewage aeration roots blower:

① Sewage treatment in environmental protection industry: biogas tank aeration, sewage treatment aeration, rural river treatment aeration, septic tank aeration, material fermentation aeration, etc.

② Other equipment requiring air supply.

③ Vacuum paper feeding in printing industry.

④ Agitation aeration of electroplating tank and industrial wastewater.

⑤ Air supply for plastic welding and blowing.

⑥ Burner spray, glass industry.

⑦ Aquaculture oxygenation, fish, shrimp and crab pond oxygenation, etc.

⑧ Sewage from hospitals and laboratories is stirred and aerated.
