Abstract

Equipment and procedure for extraction of solids from contaminated fluids whose basic purpose is to obtain the crystallised solids from the contaminated fluids, without any type of rejection in order to valorize them and to obtain purified water in a single stage, all in a continuous adiabatic/sonic process with evaporation/crystallisation and with low energy consumption and where the procedure is characterised by being constituted basically by at least three circuits fully interconnected as a single piece of equipment where the first circuit, the principal circuit, is constituted by an inlet duct of the contaminated fluid to be treated (1) followed by a pre-filter (2) followed by a filter for fine particles (3), a heat exchanger of preheated contaminated fluid (5) in the heat exchanger (4), followed by a fluid feedback pump (6) to a nozzle formed by an injector (7) and an ejector (8), which introduce the fluid to an evaporation chamber (9), where the steam that exits is introduced into a closed-loop electromagnetic servomechanism (26), an saturated steam ejector outlet (32), driven to the heat exchanger (4), outlet (13) as purified water from the saturated steam (22).

Equipment for the extraction of solids from contaminated fluids to obtain crystallised solids from contaminated fluids, without any type of rejection in order to valorize them and to obtain purified water in a single stage, all in a continuous adiabatic/sonic process with evaporation/crystallisation and with low energy consumption, comprising:

at least three interconnected circuits that form a single piece of the equipment where the first circuit, as the principal circuit, is constituted by:
an inlet duct (1) of contaminated fluid to be treated
a pre-filter (2)
a filter (3) for fine particles,
a heat exchanger (4), with two inlets and two outlets, where one outlet is for
a preheated contaminated fluid (5) heated in the exchanger (4) and followed by
a feedback pump (6) of the fluid
a nozzle formed by an injector (7) and an ejector (8),
an evaporation chamber (9),
a closed-loop electromagnetic servomechanism (26),
an ejector outlet (32) of saturated steam,
a heat exchanger (4),
an outlet (13) for purified water
the second circuit is constituted by:
an area (14) for the precipitation of solids, within the evaporation chamber (9),
a crystallisation compartment (15),
a solid discharge device (16),
an endless belt or continuous screw,
a collection container (18) for crystallised solids
a solids classifier (19),
a container for unclassified solids (19),
the third circuit, of initial brine feedback, is constituted by
a feeding duct (10) from the evaporation chamber (9),
feedback pump (11),
an inlet (12) for incorporation of the initial brine to the principal circuit
and control elements comprising:
a central data processing unit (PLC),
an HMI display and/or Smartphone terminal for users.
