Solid Foam Can Be Made Liquid

Very often the solution of ecological problems in the processing industry depends on automation and mechanization of the transportation process. The problem is that waste is often non-transportable, they viscous, capable of cohesive, agglomerated and often have a high density. Even manually extract the mass of the machine very hard. When cleaning the effluents containing suspended and surface-active substances in the ore dressing and waste, this problem is very urgent. Since we are producing equipment for the environmental problems arose mechanization and automation of sludge. Density of slurry can be reduced simply to foaming. But the foam can There are two types: solid and liquid. The first is not flowing, sticks to everything.

The second can be transported through pipelines. It was the second option, and we needed. How to make the foam has a liquid? Here and started working science, or more precisely the topology and geometry. It was necessary to create conditions where individual bubbles in the foam would not form aggregates and were able to flow, that is, to move freely. Came a brilliant idea – to equip the foam ‘Bearings’ to slip the bubbles relative to each other. And the material was found – the bubbles smaller. As it turned out binodal distribution of foam bubble size gives the desired effect. Introduction additional quantity of gas to form a fluid foam, bubbles with a given size a certain amount, with subsequent removal of gravity of the foam product, significantly simplifies the process of cleaning liquid phase from suspensions. For the formation of foam from a gas-supersaturated fluid, we used cavitation, ultrasound and vacuum. Tests have shown that this physical effect is working. Wastes are separated from ochisschennoy fluid density (foam less dense), flowing through the pipes, turn on automatic fluid foam itself strictly in terms of the mirror foam, manual labor is eliminated. Make the next step to a comfortable, highly productive labor in the field of ecology. Method eliminates the mechanical removal of the foam, manual labor, harmful effects on the environment and improves the efficiency of the process. Now the treatment facilities and processing plants can be introduced deserted technology.
