SI9600307A - Ultrasonic precrystallizer - Google Patents

Abstract

The figure shows an ultrasound crystallizer in straight form showing the housing (1), the cover of the ultrasound generator (2), the ultrasound generator (3), the digital regulator (4) and the cover of the digital regulator (5). The ultrasound generator (3) emits high density energy which precludes the formation of calcareous deposits in pipelines and other equipment. A correct selection of an ultrasound frequency will further achieve a bacterial reduction in warm water systems and a sediment disinfection in treatment plants following anaerobic and aerobic fermentation processes.

Description

DESCRIPTION OF THE INVENTION

The field of technology

Pipelines; filtering; ultrasonic cleaning.

View the problem

Hard water has different amounts of free calcium and magnesium ions and other impurities. Depending on the temperature, these are separated and bind to crystals, which are deposited on surfaces that are in contact with water, depending on the temperature. The linings are found mainly on heaters, elbows and similar pipe elements, in short on surfaces that have either a high temperature or where operating conditions suddenly change. The latter include nozzles, fittings and similar elements that represent the contact of hard water with its surroundings. Due to the deposition of crystals on the surfaces, the efficiency of the device is greatly reduced and the water quality is deteriorated. The classic methods of filtering or chemical treatment are either expensive or inconvenient (changing filters, etc.) required.

The technical problem, therefore, is to prevent the conjugation of calcium ions, magnesium and to accelerate the separation of particulate matter from the liquid in a user-friendly, simple and not expensive way.

The state of the art

The concept of softening, purifying, and separating by means of pressure waves is already known, inter alia, in U.S. Pat. No. 3,992,288, where Kling states the use of separation of objects of one specific gravity from objects of another, different specific gravity such that objects with greater specific gravity due to the action of ultrasonic waves downward, while lower specific gravity migrates upward due to the operation of conservation laws. The disadvantage of the prior art is in the use mentioned for separating solids and not for separating or purifying liquids.

In addition to sound waves, hard water softening can be achieved by using magnetic recrystallizers that are subject to different influences and perform poorly especially in different water quality, e.g. for water with a concentration of silicon exceeding 40 ppm and iron exceeding 2 ppm.

Apart from the above, water softening can be achieved with the help of chemical aids and additives, which, however, require the use of catalysts and reagents, which can leave their marks in the water and thus change its quality.

The prior art also includes US 4,244,749 where Sachs et. al. describe the use of ultrasonic transducers to clean biological liners on the outside of the tube by cavitation. A disadvantage of the prior art is that it is limited to use on the outside of the tube and on cavitation.

The prior art also covers US 4,320,528 where Scharton et al. propose the use of ultrasound to clean corrosion, oxidation, sedimentation and similar chemical products from various parts of heat exchangers, in particular from more difficult to access parts. The disadvantage of the prior art is to limit the use of the technique to stationary liners and applications related to heat exchangers.

The prior art further encompasses US 4,727,734 where Kanazawa et al. describe the use of an air-bubble-based cleaning mechanism, either induced or induced by the use of an ultrasonic generator. The disadvantage of the prior art is the use of the method in stationary or moving tanks, but not in pipe systems, and in limiting the cleaning effect of air bubbles.

The prior art also includes US 4,752,401, where Bodenstein proposes to purify drinking water or technical water in a recirculation device where the water comes in direct contact with the ultraviolet light. In doing so, it also uses an ultrasonic generator, but it only limits the cleaning of the surface of the ultraviolet light, but not the water itself, which is a major disadvantage of the prior art.

The state of the art is also covered by CA 583869, where Masri describes a circulating water purification system using ultrasound in the range of 15 to 150 kHz for a period of at least 12 seconds, which causes cavitation. These limitations are the main disadvantages of the prior art.

The state of the art further covers US 5,059,331, where Goyal describes a fluid filtration system using ultrasonic energy and a combination thereof with the effect of water return shock. The main disadvantage of the prior art is that it is limited to the cleaning of the linings by immersing the element.

The state of the art also covers US 5,085,783, where Feke et. al. describe the separation of particles from a fluid in an elongated chamber through which a fluid passes and in which an acoustic wave operates, through which the particles can be guided to one part of the chamber while the fluid flows into the other part of the chamber. The disadvantages of the prior art are in the limitations on the design and use of the technique and in the design of the device itself.

The state of the art is also covered by JP 1-301843, where Ushimaru et al. describes the use of an ultrasonic generator in a water tank to eliminate some of the components that have arisen from the chlorination of water. The disadvantage of this prior art is the necessity of using a water tank.

The prior art also includes US 5,466,367 where Coate et. al. describe the use of ultrasound to induce coagulation and precipitation in industrial effluents, which is also a major drawback of the prior art.

The prior art also includes JP 5-250537 and JP 6-028099 where Dokhu et al. describe the cleaning of objects by ultrasound in several consecutive steps. The main disadvantage of this state of the art is precisely the limitation to the cleaning of stationary objects in a water reservoir.

An ultrasonic generator is used as one of the essential components of the current state of the art. It is a device that converts the input energy, which is either electrical, mechanical, or some other form of energy into pressure waves that manifest as high-frequency sound, called ultrasound. The ultrasonic generator is described, either directly or by reference, in the patent applications described above, which are incorporated herein by reference.

Description of the new solution

The object of the present invention is an ultrasonic recrystallizer that successfully solves problems present in the prior art. An essential part of the object of the invention is an ultrasonic generator, which, due to its high specific energy, prevents the coupling of calcium and magnesium ions in warm water and thus the formation of limestone deposits in pipelines and other equipment.

The ultrasonic generator (3) is attached to the recrystallizer housing (1), which is installed in the pipeline, the housing can be except in straight line and angular, and a combination with a flowmeter or calorimeter is feasible. The ultrasonic generator (3) is protected by a cover (2). A digital controller (4) is mounted on the cover to control the frequency and volume of the ultrasound generated by the ultrasonic controller (3). The digital controller (4) is also protected by the cover of the digital controller (5).

The object of the invention can be used in installations for the preparation of drinking water, central heating and any other device in which limestone deposits are eliminated due to the elevated temperature in the water. At the same time, the use of an ultrasonic recrystallizer does not affect the quality of the water, and at the same time the device is environmentally friendly.

The object of the invention can be connected anywhere in the system, but the most appropriate seems to be the connection to the cold water supply directly in front of the hot water production plant or to the drinking water supply to the facility so that all consumers have soft water at their disposal. However, it is also possible to connect the object of the invention directly to all types of hot and hot water production plants. Furthermore, ultrasound can be directed with a specially designed screen to the desired location, taking into account the fact that the incident angle of sound to the screen is equal to the reflectance.

Successful operation of the invention requires the correct choice of ultrasound frequency, which depends on the size of the device and the distance from the device to the end users, that is, the heating elements and nozzles on which the lining is most commonly formed. By properly selecting and changing the frequency, in addition to water softening, you can achieve:

- bacterial disinfection in hot water systems so that thermal disinfection is not required;

- reducing the consumption of washing powder because ultrasound helps to break down dirt;

- reducing the use of cleaners on sanitary and other equipment as no limestone deposits are accumulated on it;

- disinfection of sludge in treatment plants after anaerobic and aerobic fermentation has been completed.

By incorporating the subject matter of the invention into drinking water wells and pumping stations, chlorination of water can be substituted as ultrasound destroys the bacteria present in the water.

A number of ultrasonic generators can also be installed around the perimeter of each enclosure.
