1、 QSB2.2 Principle and Application of Submersible Jet Aeration Machine

The stainless steel submersible jet aerator generates high-speed water flow through the nozzle generated by the submersible pump, and creates negative pressure around the nozzle to suck in air. It mixes with the water flow in the mixing chamber and generates a water air mixed flow in the trumpet shaped dispersing tube, which is ejected at high speed and contains a lot of water The water flow of bubbles swirls and mixes in a large area and depth of water, completing aeration, and its axial power does not change with the depth of submergence, and the air intake can be adjusted. Because of this, submersible jet aerators can be applied in pools with significant changes in water level.

IIQSB2.2Main features of submersible jet aerator:

　　1. The stainless steel submersible jet aerator has a compact structure, small footprint, and convenient equipment. The aerator consists of a submersible sewage pump, an aerator, and an intake pipe, with a compact structure and a small footprint; In addition, the aerator provides two types of equipment, which are convenient and easy to protect.

　　2. Stainless steel submersible jet aerator has high aeration efficiency and a wide range of applications. Due to its high-speed jet flow state, abundant liquid gas mixing, high oxygen absorption rate, and high power efficiency. The treatment efficiency is 3-4 times higher than traditional aeration tanks, and the aeration time can be significantly shortened. It is suitable for various sewage treatments, including push flow aeration tanks, mixed aeration tanks, delayed aeration tanks, oxidation ditches, oxidation ponds, etc.

　　3. The stainless steel submersible jet aerator system is simple and highly reliable. No need for equipment such as blowers, simple system, except for the suction port, all other parts are submerged in water for operation, with low noise; The aerator is equipped with a dedicated submersible sewage pump with a cutting edge, which is efficient, unobstructed, safe and reliable, and has a long service life.

　　4. Stainless steel submersible jet aerator has low investment and operating costs. Because jet aerators are suitable for deeper aeration tanks, they reduce the footprint, simplify the system, save investment costs, have high treatment efficiency, and save operating costs.

3、 Scope of use of stainless steel submersible jet aerator:

　QSB2.2Submersible jet aerator is a specialized aeration equipment used in water pretreatment and sewage biochemical treatment technology, for aeration and mixing in aeration sedimentation tanks, pre aeration tanks, oxidation tanks, etc; Submersible jet aerators can also be used for oxygenation of aquaculture ponds and maintenance of scenic water; The submersible jet aerator can also be used in the front-end iron and manganese removal technology of tap water technology, as well as in the water replenishment and circulation technology of high-rise buildings.

4QSB2.2Applicable working conditions of submersible jet aerator:

　QSB2.2The deep water self-priming submersible jet aerator can operate continuously under the following conditions:

　　1. The maximum medium temperature shall not exceed 40 ° C;

　　2. The pH value of the medium is between 5 and 9;

　　3. The medium density shall not exceed 1150kg/m3.

Jet aeration device is a type of aeration device that uses a jet injector to treat wastewater in an aeration tank. It is a type of aeration device used in wastewater activated sludge biological treatment systems. The mixture of mud and water is pumped into the jet aerator nozzle by a water pump and sprayed out at high speed. In the jet aerator, the oxygen transfer process is achieved by surrounding the jet aerator nozzlecompressed air(or directly inhaling air) mixed with mud and water mixture and vigorously stirred in a roaring tube, the bubbles are crushed into mist, and then in the diffusion tube, due to the speed head becoming a pressure head, the fine bubbles are further compressed, and oxygen is quickly transferred to the mixed liquid, thereby strengthening the oxygen transfer process. The oxygen transfer efficiency can be improved to20-25% or more

Working principle of jet aerator:
Under the high-speed rotation of the pump impeller, the liquid flows at a high speed fromWhen the nozzle sprays and the high-speed flowing liquid passes through the mixing chamber, a vacuum is formed in the mixing chamber, and a large amount of air is sucked in through the air duct. After the air enters the mixing chamber, it vigorously mixes with the liquid at the throat to form a gas-liquid mixture, which is discharged through the diffusion tube. The air rises in the water as fine bubbles, forming efficient material transfer throughout the process.
