Description

Method for purifying water and the device of implementing said method

The present invention relates to method for purifying water and device at home; It rely on to remove the biological property that dissolved gases in carcinogenic and mutagenic material and the water improves water; And relying on freezing and crystallizing through closed volume to make to pollute feed water to be separated to be pure water and polluted water to come the concentration of heavy isotope (heavy hydrogen and tritium) in the remarkable minimizing water, the present invention is suitable in daily life, foodstuffs industry and medical science, using.

Biosystem is to water (H ₂The reaction of effect O) depends on that the quality and quantity that the water isotropic substance constitutes is well-known.Have the water of high heavy isotope concentration, particularly heavy hydrogen, thereby cause limiting the application of water in treatment [referring to Kushner at the clear and legible toxic reaction of health aspect; D.J., Baker, F.; Dunstall; T.G., Can.J. physiology pharmacology (Physiol.Pharmacol.) in February, 1999,77 (2): 79-88].Simultaneously, the positive biological activity of the water that in some technical matters, produces classified as light isotope water and, find that in some biological projects to a certain extent, [referring to Somlyai, G. fights with cancer to come feed water to reduce heavy hydrogen concentration relatively! ), Akademiai Kiado, Budapest, 2001].

The biological activity that disclosed digital proof snow-broth or thawing water also arranged the effect of stimulation aspect plant-growth and the development be significantly [referring to Rodimov, B.N., " snow-broth is to the effect of active object "; Siberian and Far East agricultural crops, Omsk, 1965; 56-57 page or leaf (Agricultural Productions of the Siberia and Far East; Omsk, 1965, pp.56-57)].The increase of heavy isotope concentration has changed the normal path of Biochemical processes in human body, has therefore weakened the function of health.The result is exactly to increase at daily tap water ¹H ₂ ¹⁶The amount of O.

A kind of method of disclosed treating water comprises from feed water produces ice, thaw it and collect thawing water.The production of ice realizes [referring to Denisov, I., and Matveev, S., " drinking pure water (Drink Pure Water) ", Rabotnitsa magazine, Moscow, 1991,11 phases, 34-36 page or leaf] through part cooling (approximately being 2/3rds volumes) feed water.Because water is all being stopped freezing and is being discharged not refrigerated residuum before freezing, melt the water that obtains through " ice cup (an ice cup) " and reduced heavy metal and some isotopic concentration.

Therefore, this method can not provide the reduction of heavy (heavy hydrogen and tritium) water molecules level in the thawing water; They have together become ice with light (light hydrogen) water.Further, above cited method does not provide water effective structurizing, does not provide the condition of the performance that influences gained water that it provides yet.

The device that is used for implementing this art methods is presented as family or industrial refrigerator (refrigerator); It comprises a case; Its mounted inside has the chamber of admittance feed water and the refrigerating unit of pond form, and [referring to technology dictionary (The Polytechnic Dictionary), Academician N.I.Artobolevsky edits, Moscow; 1977,546 pages].The defective of this art methods and this prior-art devices comprises that they can not provide separating and the biological nature that can not improve water significantly of the heavy water of having removed heavy water and light-water.

A kind of disclosed through the freezing method that improves drinking water quality; Comprise that water-cooled freezes, ice is broken, and ice-out; Be characterised in that feed water is freezing to the 70-90% of original volume and the thawing of ice; Its through thermal isolation the ice of side and bottom surface account for the 30-55% that is removed volume subsequently [referring to russian patent No. 2077160, ICL C02F1/22, on April 10th, 1997 is open] until the thawing water that flows away.

The method of the high-quality tap water of known preparation comprises and removes undissolved mechanicalness impurity, removes chlorine, and is softening, removes organic substance and venting step; Their defective comprises the tap water that high purification can not be provided, and does not also have treatment characteristic (European patent 0249049, IC C02F 9/00,1987 in addition; European patent 0312079, IC C02F 9/00,1989).

Further, known preparation has the method for high purification tap water of treatment characteristic, except that comprising the water purifying step, also comprise water-cooled freeze step (referring to USP 1799367, IC C02F 9/00,1991; Russ P 2010772, IC C02F 9/00,1992; With Russ P 2031085, IC C02F 9/00,1992).

A kind ofly knownly freeze large-scale purification water method and the device that is used for implementing this method (referring to Lyubarsky through water-cooled; V.M., natural water deposition and handle their method (Precipitation in Nature Waters and Methods for Processing Them), Moscow; Stroyizdat; 1980, the 98-99 page or leaf, Figure 22).This device comprises in order to the pond that holds water with in order to cool off the technique device of (freezing) and heating (thawing) water.

A defective of above-mentioned quoting method possibly be since lack freezing and thawing mode that select to optimize (speed, time, and design temperature, and other) the low-level purification of water that causes.

Another kind of known (referring to " suggestion of making provision against emergencies (An Advice Just in Case) "; At Rabochaya Tribuna newspaper; Moscow, the 21st phase (321), on January 30th, 91) pass through the freezing method that purifies household drinking water and the device of implementing this method (referring to Russ P 2058262; IC C02F is open on April 20th, 1/22,96).This method comprises injects the pond with water, at first the pond is placed in the refrigeration chamber; Water coolant is until form the thick and heavy hydrogen ice sheet of 1-3mm on the surface; The pond is moved apart refrigeration chamber and removes the heavy hydrogen ice sheet; With the pond be placed on refrigeration chamber for the second time and be maintained until clean ice sheet and do not purify, chemistry is unclean, refrigerated water (residual brine) forms; The pond is moved apart refrigeration chamber and will totally icing with residual brine separates; Ice with melting totally.In second time refrigerating process, the feed water that contains with the impurity of dissolved salt, organism and agricultural chemicals form is separated into fresh clean ice and residual brine; The latter is concentrated in the central zone of refrigerated water for the first time.

The art methods that this water purifies has following defective:

-two independently water-cooled freeze step and two independences and increased the complicacy that water purifies from the separating step of ice and ice; It is not easy to remove heavy hydrogen (weight) water; Because need to move apart refrigeration chamber to the pond, pour into new (temporarily) pond to refrigerated water not, remove the upper surface of water and first ice sheet (1-3mm is thick) of bottom, main pond and peripheral formation; Pour into main pond to water from interim pond, be placed on main pond in the refrigeration chamber; And only remove first ice sheet from upper surface, do not pour water into interim pond, it uses in front the step sometimes, has increased the heavy water residual volume in the water purification.Because these defectives, although it is very high to obtain the issue requirement of " one glass of clean tap water ", the method for purifying waste water through freezing mode this obviously " simply " does not have widespread usage in the family.

One device (on April 20th, 1996 is open for USP 2058262, IC C02F1/22) through freezing purifying drinking water; This device comprises in order to place the pond (container) of water; Top cover is fluted to place freezing ice sheet for the first time, and the bottom is fluted to place water and the freezing ice sheet second time, heating unit; Sluice is providing bottom and lid to the pressure of container, and the packing ring between lid and container.

The defective that should have family's water treatment technology device now is following: complicated design; Because only remove heavy hydrogen ice, mean that removal quantity is insufficient from the top surface that is frozen water; Because the ice forming process occurs in whole internal surfaces of container, also be difficult even therefore only remove heavy hydrogen ice from top surface; And, therefore separate clean ice and residual brine is difficult through the removed bottom mode that a dark groove is arranged because ice for the second time that forming process occurs in the totality surface and be not from top to bottom.

The one known water purifier of drinking thawing water in order to production; It comprises the extension container; Its internal series-connection arranges with annular refrigeration chamber refrigerated water zone, and impurity is extruded in salt solution spissated zone and is equipped with annular heating unit from ice water is transformed into region of fluid (Russ P 23412817 from solid; IC C02F is open on December 20th, 1/22,2007).This water purifier has independently outlet pipe drink thawing water to remove like brinish impurity and removal; The separating unit that is placed on the refrigerator next door of two bottoms that all are set at container and extra assembling is to move refrigerated water rod and to be placed on the separating unit at refrigerated water rod center with the form of pipe.There is circular cutting part and its exit section to launch in this separating unit ingress to remove like brinish impurity.

Yet it is big that this device is implemented complex structure and refrigeration chamber size and weight, stoped it to use in the family like this.

The one known water purifier that is used for drinking on a large scale thawing water from seawater production; It comprises the extension container; Its internal series-connection is arranged with annular refrigeration chamber refrigerated water zone; Impurity is extruded in salt solution spissated zone and is equipped with annular heating unit from ice water from solid be transformed into region of fluid and all be arranged on container than the independent outlet pipe of lower part with impurity in the discharging salt solution with drink thawing water (referring to FRP 2858607; IC C02F is open on February 11st, 1/22,2005).

Yet this device also has the large size refrigeration chamber and because the whole installation weight that is used for desalinizing seawater on a large scale is big, has stoped it to use in the family like this.Further, this device can not provide the chance of removing heavy (heavy hydrogen and tritium) water, has therefore weakened product gas purity and has therefore weakened application characteristic.

One knownly includes the lid and the pond of conical bottom in order to the device of purifying waste water, have in it be used for discharge water the hole and be used for refrigerated water and melt the electrothermal module of icing; The pond of pond that acceptance is purified waste water and the polluted water that receives the raising of heavy hydrogen level; The electrothermal module control unit; Be used for the conduit of discharge water; One end is connected to refrigerated water and is equipped with valve with the interior drain and the other end of the conical bottom in the pond of melting ice; Its pond that thawing water that is used to receive purification is installed respectively down and the pond that is used to receive the polluted water of the heavy hydrogen level that contains rising are (referring to Japanese Patent 5123668; IC C02F 1/22, F25B21/02, on May 21st, 1993 is open).

Yet this device has one cooling or heating unit in electrothermal module, and this unit is placed on the one side in pond, does not therefore allow water evenly to melt and reduced the quality of water decontamination with a large amount of evenly freezing or ice of rotational symmetry spiral tube form.In this device, can not allow this device between circulation, to prepare operation fast and the automated manner operation can not be provided in order to the blowdown system of emission purification water (thawing water) and polluted water, therefore reduced the operability of this device.Further, this device can not provide the removal of heavy (heavy hydrogen and tritium) water, has therefore weakened product gas purity and has therefore weakened application characteristic.

Maximally related art methods is included in the method (Russ P 2274607 of purifying waste water in the pond; IC C02F 1/22; On April 20th, 2006 is open); Comprise the heat abstraction through heat exchanger mode, this heat exchanger is arranged on the pond internal upper part apart from about 1/3 to 2/3 height of the top of liquid cylinder liquid level, with the equidistant position in center, pond and side; And 1 temperature head in (1) ℃ is provided, this temperature head surroundings provide ice crystal continuously, progressively with local volume (local-bulk) crystallisation process of the rapid refrigerated of multistep.For purifying waste water; Carry out following operation: continuously, progressively quenching is frozen to their amount and is no more than the size of the 50-70% of feed water total amount with multistep at the surroundings ice crystal; The refrigerated polluted water is not discharged from the pond; Ice unfreezes all, and filters through secondary filter when for the second time freezing amount and the discharging thawing water to thawing water sum 3-7% of part is in order to consumption.Polluted water is melted the back from the different levels part of the height along the pond and through different conduit dischargings with thawing water; Wherein polluted water is discharged through the conduit that is arranged on minimum base, bottom, pond, and thawing water is through being arranged on the conduit discharging of 0.5-2 centimetre of top, bottom, pond.

Thawing of ice through the enforcement of two steps; Wherein the first step comprises to separate to freeze to all containing the long-pending 90-95% of lower concentration heavy hydrogen isotropic substance ice body and second step and comprising thaw on heat exchanger residue crystalline and the ice that comprises high weight percentage hydrogen isotopes (heavy hydrogen and tritium) for the first time.Thawing through continuous elevated temperature of ice to reaching evaporating state and the vapor film convective transfer of heating being realized to the temperature that is not higher than 40-80 ℃.Through the pond side perimeters around shielding cable heating realize thawing of ice.

Maximally related prior-art devices comprises water-purification plant (Russ P 2274607; IC C02F is open on April 20th, 1/22,2006), comprise not purification water pool; Be installed in inside, pond to remove the heat exchanger of heat and freezing ice; Heating is also separated the device that freezes, and freezing unit and cooling system thereof have the conduit of the exhaust emission water of valve; Conduit with the discharging thawing water that valve is arranged; This device is characterised in that: heat exchanger be multistage coil form and be placed on top, pond, be approximately the pond height 1/3 to 2/3, to top 2-5 centimetre the distance in pond and with side, pond symmetry, the gap that has makes that ice refrigerated volume size maybe not can be blocked this gap because of crystal ice in the coil pipe ambient water, heat-insulating lid and tightness system are assembled in the pond; The pipe of exhaust emission water is installed in pond conical lower section apex portion, and discharging thawing water conduit is installed in conical base top, pond 0.5-2 centimeters.This device is equipped with secondary filter, and the water discharge spout of valve is arranged, and is used for circulating and transmits thawing water pump through secondary filter and have manual work or the control unit of operational mode automatically under pressure.

It is not enough that the main drawback of maximally related existing method and apparatus comprises that water purifies quality; Be because the heat exchanger in the equipment is positioned at work pool and the integral body that can not feed water provides freezing ice-out to form axisymmetric annular solid or to have uniformly, therefore reduced the quality of water purifying contaminated thing and heavy hydrogen.The size of equipment is big with the weight of freezing unit that has cooling system, and the useful volume part that water-cooled is frozen the pond occupied by heat exchanger, and heat exchanger is a coil form, has increased the size of equipment and made to use difficulty at home.

The technical result that requires protection to invent comprises the creation of method for purifying water and equipment; Therefore increased the quality of water purifying inorganic salt, organic matter and heavy (heavy hydrogen and tritium) water pollutant; Reduced and produced the time of finished product and the weight and the size of equipment, and improved the accessibility of using this equipment through the thawing water production technique fully automated that makes purification.
