Purun Ying air flotation machine equipment

Vortex concave air flotation machine
The vortex concave air flotation machine mainly uses the OLTE vortex concave aeration head to rotate the aeration impeller at high speed, so that the gas is quickly dispersed in the liquid, achieving the effect of air flotation. The high-speed rotating aeration impeller rotates at a speed of 2900 revolutions per minute. However, the gas entering the liquid from the impeller cannot quickly diffuse. The second blade cuts it into two bubbles, repeatedly rotates and cuts at high speed, and then reaches tiny bubbles, producing an air flotation effect. For example, the products of Dalian Three Phase Machinery Equipment Development Co., Ltd. can reach bubble diameters of 20-50 microns
OLTE dissolved air flotation machine
OLTE dissolved air flotation machine mainly achieves air flotation effect by dissolving and supersaturating gases and releasing them into the flotation tank
Dispersed air flotation machine
The dispersing air flotation machine mainly achieves the effect of air flotation by crushing bubbles through a disperser
Ultra efficient shallow air flotation machine
The super efficient shallow air flotation device is a type of air flotation system that has been successfully designed using the 'shallow pool theory' and the 'zero velocity' principle. It integrates coagulation, air flotation, skimming, sedimentation, and sludge scraping, and is an efficient and energy-saving water purification equipment CQJ type ultra efficient shallow ion air flotation is an air flotation device that integrates flocculation, air flotation, skimming, and mud scraping. It is designed using the 'shallow pool theory' and the 'zero velocity principle', with a residence time of only 3-5 minutes. The water is forcibly distributed, and the inflow and outflow are static. The adhesion between microbubbles and flocs occurs throughout the entire air flotation separation process, including the contact zone. The floating slag is discharged instantly, and the water disturbance is small. The effluent has low suspended solids and high solid content in the slag. The removal rate of suspended solids can reach over 90% -99.5%, the removal rate of COD can reach 65% -90%, and the removal rate of chromaticity can reach 70% -95%.
The CQJ type ultra efficient shallow ion air flotation adopts a high-level technology - the balanced energy dissipation device replaces the traditional release device, significantly reducing the diameter of microbubbles. The average diameter of microbubbles is only about 5 μ m, which is at least 30 times smaller than the current average of about 150 μ m at home and abroad. Due to the fact that the total area of microbubbles is inversely proportional to the square of their diameter when the dissolved gas volume is constant, the total area of microbubbles increases by at least several hundred times, while the density of microbubbles increases by nearly several thousand times. Theoretical research and experiments have shown that the smaller the diameter of microbubbles, the stronger their tendency to adsorb suspended solids and the greater their adsorption force. This can be explained by the interface energy theory. The geometric increase in the total area of microbubbles is equivalent to the geometric increase in the total surface area of solid, water, and gas phases in wastewater. Therefore, their tendency to reduce surface energy through adsorption is greatly enhanced. In the theory of air flotation, the separation of suspended solids from water involves not only the mechanisms of bubble adsorption, bubble support, and floc adsorption, but also the so-called 'bubble entrainment' effect. Some small suspended solids that have not been adsorbed by bubbles or flocs may be carried to the water surface during the rise of dense bubbles, regardless of how small they are, because their particle size is still much larger than that of water molecules. They may be entrained in the gaps between bubbles in the bubble group and carried to the water surface for separation. Obviously, the denser the bubble group, the stronger this effect will be, and the suspended particles it can carry will also be smaller.
*The gas dissolution system is designed with a small volume, high gas dissolution efficiency, and compact structure. The equipment has a small footprint and high efficiency.
