US 2021/0164876 A1 · Submersible System and Method for Measuring the Density and/or Concentration of Solids in a Dispersion

Abstract

The invention relates to a submersible system (1) for measuring the density and/or concentration of solids in a dispersion, which can be in the form of a liquid, a mixture of multiple liquids, a suspension of solids in liquid, or a combination of these forms, inside of a reactor (11) into which gas in the form of bubbles is introduced, the system comprising: an open, pass-through gas exclusion device (4) having a tubular body (5) with a variable cross-section through which the dispersion without gas bubbles enters, the device coupling to an inlet tube (6); a scaled chamber (8) that has a means for measuring density, when the dispersion circulates between an inlet (14) of the sealed chamber (8) and an outlet (15) of the sealed chamber (8). The outlet (15) of the sealed chamber (8) is coupled to an outlet tube (7) through which the dispersion returns to the reactor (11) in which same is being processed. The system also comprises a transmitter (9) connected to a sensor, which generates an output signal proportional to the density of the dispersion without gas bubbles by means of the sensor located inside the sealed chamber (8); and a processing unit (10) that generates an output signal (16) proportional to the concentration of solids in the gasless dispersion, as well as the pulp density. The invention further comprises a method for obtaining the concentration and density of the pulp.

A submersible system (1) to measure the density and/or concentration of solids in a dispersion, which may be in liquid form, a mixture of multiple liquids, a suspension of solids in liquid, or a combination of these forms, within a reactor (11) whereby gas is introduced in the form of bubbles, CHARACTERIZED in that the submersible system includes:
an open and pass-through gas exclusion device (4) which has a tubular body (5) of variable cross-section, where the inlet opening through which the dispersion without gas bubbles entered the open and pass-through gas bubbles exclusion device (4) is greater than the outlet opening where dispersion without gas bubbles is released from the open and pass-through gas bubbles exclusion device (4), and where the outlet opening joins an inlet pipe (6);
a sealed chamber (8) consisting of a means to measure the density, which comprises at least a sensor which allows measuring of the density of dispersion without gas, when circulating between a intake (14) of the sealed chamber (8) and an outlet (15) from said sealed chamber (8), where this intake (14) of said sealed chamber (8) is attached a this inlet main (6), and where said output (15) of that sealed chamber (8) is attached to an outlet pipe (7) through which the dispersion returns towards the reactor (11);
a transmitter (9) connected to this density sensor, located inside or outside of said sealed chamber (8), where said transmitter (9) generates an output signal proportional to the density of dispersion without gas bubbles through the sensor located inside the sealed chamber (8);
and
a processing unit (10) that creates an output signal (16) which is proportional to the concentration of solids of the dispersion without gas εs in volume or weight, and also the density of the slurry ρp.
