Deep water aeration mixer
SBJ deep-water aeration mixer is an integrated product of electromechanical technology and biochemical technology. It is a special equipment for solving high concentration organic wastewater and realizing high-efficiency oxygenation in the process of biochemical treatment; The main engine adopts the design of two speed motor, which has the dual effects of high-speed aeration and low-speed mixing, and the working performance of diving depth up to 20m. It is an irreplaceable product of traditional aeration equipment
SBJ deep-water aeration mixer is mainly used in nitrification / denitrification tank, SBR reaction tank, sludge tank, oxidation pond and places requiring deep-water aeration mixing and high oxygen transfer rate.
Structural features
SBJ products are composed of submersible motor, reducer, impeller, mixing chamber, base, gas transmission pipe and lifting chain.
1. Deep water: due to the use of deep-water motor sealing technology, the aeration tank is arranged in the vertical direction, and the tank depth can reach 20m, which can save the floor area and reduce air pollution; Due to the water depth, the air stays in the water for a long time, and the underwater temperature is balanced, so the oxygen transfer rate is high.
2. Aeration: SBJ product is composed of air supply system and high-speed mixer. The actual oxygenation capacity is completed through the mixing function of inlet air and water. Therefore, as long as the water-gas mixing ratio and working time are controlled, the required better continuous and stable aeration performance can be achieved; This makes the automatic control system of biochemical treatment process simple and reliable. Experiments show that bubbles are dense and uniform on the water surface of SBJ. The negative pressure formed by the impeller in the state of high-speed movement also increases the self-priming function of the machine, so as to improve the dynamic efficiency of the whole machine.
3. Mixing: SBJ product is used as the aeration mixing equipment at the bottom of the tank. It uses the open impeller structure design and has no worry of blockage. After completing the high-speed aeration, it can automatically switch to the low-speed state as the mixing equipment. The flow rate can be maintained at the outlet along the circumference of 3-5M / s. through the reflection of the tank wall, it can form a circulating flow under the water, which can effectively prevent the settlement of suspended solids.
4. Installation: SBJ products are positioned by self weight. The integrated hoisting design does not need any auxiliary accessories, and the layout is flexible. Rapid hoisting can be realized without drainage and interruption of process operation.
In addition to the above four characteristics, it also has the advantages of less civil engineering investment, simple operation and low operation and maintenance cost; It adopts double mechanical seal design and multiple electrical protection functions, which makes it safer and more reliable to use.
1. The aeration mixer is installed at the bottom of the tank and positioned by self weight;
2. The air suction pipe is connected with the blower air delivery pipe by flange on the water surface. The blower can be directly installed in the sound insulation cover beside the pool or in the factory
Structure and process
The deep-water aeration mixing machine is composed of submersible motor, reducer, impeller, mixing chamber, base and air inlet pipe. The impeller of the deep-water aeration mixer rotates in the mixing chamber to inhale compressed air. Because the impeller with special structure rotates relative to the mixing chamber, the air is cut into small bubbles. At the same time, the water is sucked in and completely mixed with the chopped air, and the gas-liquid mixture is sprayed out in a horizontal direction through the channels around the mixing chamber. In this way, the micro bubbles are evenly filled into the liquid for aeration, which increases the contact between the gas-liquid two-phase surface and improves the efficiency of the aeration system. The large exchange area and the high turbulence of the sprayed gas-liquid jet can greatly improve the oxygen transfer rate and oxygen charging
