Розглянуто проблему гідросепарації вторинних полімерів. Розроблено математичну модель процесу, проаналізовано умови занурення полімерів у воду та їх відокремлення від інших твердих побутових відходів.
Hydraulic separation is a way of separating solid waste (MSW) into components with water. The technology is cheaper than incineration, with relatively rapid deployment. With the technology of hydro solid waste can be recycled up to 85 % of unsorted waste, which then will be used to rework both recyclables and organic waste – production of biogas and electricity.
For hydraulic sorting of solid waste using water, which is a natural odor neutralizer. Originally unsorted waste coming into the emergency department, equipped with exhaust fans. They were then passed through a stream of water where organic and inorganic components are separated by gravity regulate water flow.
The purpose of this paper is the problem of sorting waste by hydro polymer material in which plastics are sorted from the total weight of waste by adding air to the water, which changes its density, resulting in getting water-air mixture in which the polymers are not emerges the surface, and begin to settle, as their bulk density greater than the density of the resulting mixture.
Ten years ago, the term hydraulic separation was very new to the vocabulary used in the North American hydronics market. Back then the contemporary topic being discussed and applied was primary/secondary piping. The idea being that several loads, each served by its own secondary circuit and associated circulator, could be connected to a common primary loop, with its own circulator. The «magic» of closely-spaced tees is what prevented the flow rate in any of these circuits from interfering with the flow rate in the others.
In essence, that is what hydraulic separation is: the ability of two or more circulators within the same piping system to simultaneously operate without interfering with each other.
