FR2631022A3 - Apparatus for controlling the acid-base equilibrium of water - Google Patents

Abstract

Device making it possible to modify the TH and the phronic characteristics of water (pH, rho, rH<2>) by set-point display, continuously and independently of the consumed flow rate, comprising an ionisation chamber 4 operating without interruption, at low but continuous throughput, and feeding a storage 18 from which a pump 20 draws as required. The pumped water is then dynamised by passing through a magnetic field. The invention can be employed both when the water to be treated is strongly laden with electrolytes and in the contrary case.

Description

DESCRIPTION
Device for regulating the acid-base balance of water.

The present invention relates to the treatment of water with a view to modifying the TR or its phonetic characteristics.

In known devices of this type, only the reverse osmosis system allows the same type of result but at a cost that is prohibitive for current applications.

devices using ion exchange resins are not convenient to use, do not allow consumption of treated water, and devices known as "electronic scalers are not programmable, hold them in suspension in water instead of Discard the Calcium Carbonate molecules, which limits their applications.

The device according to the invention makes it possible to avoid these drawbacks.

In this, in fact, it is possible: a- to obtain a constant flow rate from the deionization chamber regardless of the flow rate requested on the user side.

b- to expel unwanted molecules c- to use this water for drinking with regard to its phonic characteristics.

d- display the desired output characteristic.

e- to obtain good quality water at a reasonable cost price.

f- hard freed from a restrictive interview.

The device which is the subject of the invention comprises: Plate I / 2 (This plate is a synoptic diagram and therefore does not show the actual position of the components) a- A tank 1 provided with a level 5 intended to actuate an EV 3 of filling.

This tank supplies by communicating vessel: b- An ionization chamber 4 through a graduated flow adjustment valve 5
This chamber contains: - A 6 cathode and an 8 concentric cylindrical anode.

(We reverse 6 and 8 in the case of aggressive water).

- A fine-mesh filter 7 - A central useful ion flow tube 34 - An automatic periodic rinsing system with admission and
water delivery by EV 9 and 10.

- An outlet for the unused part of the water with
its undesirable compounds II c- A measuring cavity 14 located under the ionization chamber and allowing to control the flow rate and instantaneous resistivity of the treated water thanks to an EV 13 intended to fill the said cavity from the contents of the upper part 12, Up to a resistivity measurement probe 15 and a level 16 controlling the opening of EV 17 while EV 13 closes.

The duration of the alternation is determined on the one hand by the level already mentioned 16 and by manual setting of the clock.

d- A low reserve 18 receiving water from 17.

This reserve can be coupled by communicating vessel to a larger one if necessary.

It comprises: a low level 19 making it possible to signal the deactivation of the pump 20, to launch its automatic re-priming and to allow the ionization chamber to be switched on.

It also has a high level 21 in series with Level 2 authorizing the opening of the admission by 1 # EV3.

e- A Pump 20 which directs the water either towards the reserve 18 when it is in recycling (absex of use) by the EV 21, or towards the use by the EV 22, the cooling coil 23 and the pressure switch 24 when a user tap is opened, simulated here by tap 27.

i A bypass 25 supplied by EV 26, itself controlled by level 19, allows the pump to be automatically primed.

g- Accessories (Plate fI / 2) ensuring the correct functioning of the assembly, namely an electronic box 28 comprising: - the various clocks 29 and their power supply.

- the supply of the ionization chamber 30.

- a regulation thermistor.

- a micro-ammeter graduated in kohm / cm2 / cm 32 - an induction coil through which the ionization current passes and - surrounding part of the treated water pipe.

The device object of the invention can be used in all cases where it is desired to have a water having chara ~ teristics data and stable, at an affordable cost, without the need to introduce additives in the device, and without tedious maintenance.

It can be used in laboratories and at home, but also and above all in industry, in water distribution networks, etc., whether in areas where the water is very hard or, on the contrary, in areas where she is aggressive.

Examples of applications: - Drinking water for people and animals. Breweries. Sodas.

- Bakeries - Domestic applications: dishes, linen, coffee machines
cooking food, skin and hair care,
toilet.

- Agronomic applications: accelerated germination - Industrial applications: protection of boilers,
water distribution networks, car washing, developing
photographically.
