SU1204226A1 - Apparatus for continuous ionizing of water - Google Patents

Description

The invention relates to environmental protection, chemical desalting of water, utilization and reuse of post-regeneration solutions resulting from the ion exchange desalination of natural and waste waters, and can be used in the chemical, energy, metallurgical and other industries.

The aim of the invention is to reduce the amount of ion exchange material and eliminate water loss.

The drawing shows the apparatus, a longitudinal section.

The device contains a cylindrical housing 1 with conical ionization chambers 2, devices 3 for feeding ion-exchange material, device 4 for feeding treated water, device 5 for withdrawing spent ionite pulp, device 6 for draining treated water, a recovery device 7, drainage mouth - roystvo 8, bunker-feeder 9 of ion exchanger, device 10 for removal of transporting regenerated ionite water, device 11 for supplying transporting water, device 12 for removal of ionized water from the regenerator and discharge of GOVERNMENTAL sleregeneratsion- solutions device 13 for supplying regeneration solutions, devices 14 for controlling the supply of the ion exchanger with feeder and discharge chambers with the getter, the device 15 for supplying otregenerirovannogo exchanger device 16 for controlling the water level.

The apparatus for continuous ionization of water works as follows.

The initial water from the averaging tank is pumped through the water supply device 4 tangentially to the forming surface of the ionization chambers 2 at the lower third of the height, fresh ionite is dosed tangentially through its feed device 3 to the upper third of the ionization chambers 2.

As a result of the tangential supply of water and ion exchanger, a flow turbulence and intense ion exchange occur, completed in the upper zone with material soaring, after which the saturated ion exchanger makes a counter-movement to the place of constant release to the top of the conical ionization chamber 2 and then

It goes to one of the regenerators (working) before it is filled. The ratio of the ion exchange material to the treated water is maintained within (0.2-5.0): 100, and 5-20% of the treated water is used to discharge the spent ion exchanger from the ionization chambers, which are separated from the latter in the regenerator, mixed with the original (or are used as water of higher quality purification), the transporting zone generated ion exchanger in the ionite feed bin 9, and returns the stage of loosening and washing the ion exchanger to the treated water stream, mine.

The contact time and the treated water in the ionization chambers 2 is 16-160 s with the ratio of the solid phase to the liquid in the pulp to be regenerated, which is (1-5): 100.

The regeneration of the ion exchanger is carried out in a regeneration device 7 in a dense layer of ion exchanger after separation of ionizable water from it.

3-5 min before the filling of the first regenerator, the regenerated ion exchanger from the second regenerator is overloaded with source water to the feed bin 9, and the depleted ion exchanger from the ionization chambers 2 enters the empty tank.

At this time, the filled first regenerator is brought to the regeneration stage, which is completed 3-5 minutes before the second regenerator is filled. Then the cycle is repeated.

Since the transportation of the regenerated ion exchanger to the feed bin 9 is carried out with pressurized initial water, this process ends with the stage of its washing with a massive flow of water discharged then from the feed bin 9 with residues of the restructuring solution into the averaging capacity of the source water, which also receives ionized water after separation from the ion exchanger in the regenerators, transporting the spent ion exchanger from the ionization chambers.

The regeneration solution is fed to the compacted, dewatered ion exchanger of the regenerators, and the separated regeneration solution is disposed through the drainage device 8 for disposal. The dosage of the regenerated ion exchanger in the ionization chamber 2 is carried out by a feeding device placed in the feeder hopper 9.
