Abstract
An apparatus for purifying water to be purified is provided with a tank with a bottom to receive sediment, an inlet connected to the bottom itself, at least one pump, outside the tank and connected to the inlet, at least one conduit disposed axially inside the tank, diverging upward and fluidically connected to the inlet to receive pressurized water fed by the pump, and a hydraulic accelerator/mixer assembly disposed in the tank and which connects the inlet to the conduit. The hydraulic accelerator/mixer assembly is configured to increase the speed of the flow of water to be purified, introduced into the tank.
Claims12
Apparatus for purifying water to be purified, said apparatus comprising:
- a tank for the water to be purified, which develops around a main axis of development and which comprises a bottom, conformed as a hopper, to receive sediment separated from the water to be purified, and an inlet connected to said bottom;
- at least one pump means, outside said tank, and connected to said inlet, the pump means being able to feed under pressure a flow of water to be purified in said tank;
- at least one conduit disposed axially inside said tank and diverging upward with respect to said main axis of development, said conduit being fluidically connected to said inlet to receive pressurized water fed by said at least one pump means;
- a hydraulic accelerator/mixer assembly disposed in said tank and which connects said inlet to said conduit, wherein said hydraulic accelerator/mixer assembly is configured to increase the speed of the flow of water to be purified introduced into the tank and determine a recirculation flow at entry to said hydraulic accelerator/mixer assembly obtaining a mixture of the flow of water to be purified with at least part of the sediment present in correspondence with said bottom and/or at least part of substances to be removed being deposited on the bottom);
- wherein said hydraulic accelerator/mixer assembly is of the multi-stage type and comprises at least two accelerator/mixer devices disposed connected in sequence along said main axis of development.
A method to purify water to be purified, said method comprising:
- introducing under pressure a flow of water to be purified into a tank that develops around a main axis of development, to determine the formation of sediment separated from the water that deposits on a bottom conformed as a hopper, wherein said water to be purified is conveyed through an obligatory path formed by at least one conduit disposed axially inside said tank and diverging upward with respect to said main axis of development,
- increasing the speed of the flow of water to be purified introduced into the tank by means of a hydraulic accelerator/mixer assembly connected at entry to said conduit and recirculating water to be purified at entry to said hydraulic accelerator/mixer assembly obtaining a mixture of the flow of water to be purified with at least part of the sediment present in correspondence with said bottom and/or at least part of substances to be removed which deposit on the bottom;
- wherein the increasing in speed of the flow of water to be purified and said recirculation of water to be purified are carried out by means of sequential multi-stage operations of speed increase and recirculation by means of at least two accelerator/mixer devices disposed connected in sequence along said main axis of development.
