The object of the present invention is a method of recycling organic compounds which in addition to such elements as carbon, hydrogen and oxygen, contain halogen, phosphorus, sulfur and/or elements of the metals in an atomic communication, and a device for implementing this method.

Substances which contain halogen-free, phosphorus, sulfur and metal atoms, such as mercury, arsenic, etc. that are used in various applications. Thus, they can serve as cooling agent is some scope in this regard are fighting toxic substances. In all such cases, among other things, there is the problem of disposal of these often extremely dangerous toxic compounds. This should be destroyed residues from the manufacture, stored, often also those who after receiving prohibited by law, the standards, the residual amount of consumers, etc.

This is often available by disposal by burning. Organic compounds that contain only carbon, hydrogen and oxygen, with sufficient supply of oxygen to fully burn damage with the formation of carbon dioxide and water. However, especially in the presence of halide compounds formed during the incineration of hazardous dioxins represent an obstacle for this kind of neutralization.

The aim of the present invention is to provide a secure method of destruction, disposal or recycling of such substances.

The basis of the present invention based on a knowledge that is electrically charged ions or parts of molecules through electrodialysis can be separated from each other. In organic compounds with atomic, i.e., non-polar, binding of interfering elements such division is the expense of electrical energy.

Therefore, according to the invention, recyclable organic compounds proposed to be subjected to ionization, after which the formed bearing charges of the products of ionization are separated by electrodialysis and end-ion products, as well as the remaining organic matter submitted for itself known to the application or sent to storage or for burning.

Ionization can be achieved by exposure to ionizing radiation.

When this atomic communication polarized, recyclable substance disintegrate to ion products and it becomes possible to carry out the separation of differently charged particles due to the impact of electrical energy. As soon as initially associated atomic elements move in ionic form, they can be more easily manipulated, and they can easily be disposed of or sent to another application. Thus, there is disposal of hazardous compounds without previous hazards arising from the destruction of thermal path.

Preferably so disposed of toxic chemicals, such as pesticides, herbicides, fungicides, and kalogeropoulou, chlorinated transformer which I organic halide compounds, in particular those in which the halogen is bound to an aromatic ring, preferably phenyl ring.

Here, for example, should be substituted by chlorine, bromine and/or iodine derivatives of benzene, which is preferably optionally substituted by one or more hydroxyl, cyano, alkyl groups or esterified carboxyl or carboxyaniline groups.

Practical examples are dibromo - or diiodohydroxyquinoline and chlorocyclopropane acid. The combination of these compounds is used in agriculture as a herbicide called ANITENR.

However, using the proposed in the invention method can also be recycled halogenated polyfamily, preferably polygalacturonic biphenyl (PCB), which is used as transformer oil.

Further the problem of disposal are aliphatic kalogeropoulou (FCKW), which is used as a cooling means and a blowing agent. Their disposal is also an object of the present invention.

Ionization recyclable compounds can be accomplished using Lanthenay the form used for this purpose conventional x-ray apparatus, from which seized used for shielding unwanted beta - and gamma-radiation of the aluminum plate.

Recyclable substance is preferably in a liquid state, in particular in the form of a solution, preferably in aqueous solution.

Preferably the ionization and device for dialysis combine in spatial terms, as the lifetime of the formed ion products, primarily by ionization by radiation, often relatively short.

Thanks ionization must be created with a minimum conductivity of a solution of 500 S (s) to achieve the target action.

The object of the present invention is also a device for implementing this method.

The device is illustrated by the attached drawings, where:

in Fig. 1 shows the preferred dialysis ionization device for implementing the method,

in Fig. 2 shows the General placement of such devices inside the General settings used for this purpose, and

Fig. 3 is an advanced setting with enhanced multichamber electrodialysis system.

In Fig. 1 shows the preferred mnogovato 2 introducing the raw material solution. This camera 1 is ionization. Preferably the ionization is carried out by ionizing radiation. Through the anode 3 and the cathode 4 miss DC and due to its impact separates ionized component parts. To the Central chamber 1, depending on the circumstances, adjacent analita camera 7, which is separated from the camera 1 membrane 5 or 6, and Catalina camera 8. Of these cameras 7 and 8 through the outlet pipe 9 or 10 output inorganic part in the form of a concentrate.

Organic material, which after ionization remains in the chamber 1 and cannot diffuse through the membrane 5, 6, divert through the exhaust pipe 11 of this camera as diluate.

To analtoy chamber 7 and Catalinas chamber 8, depending on the circumstances, adjacent the anode chamber 14 separated by a membrane 12 or 13, and the cathode chamber 15, in which the boot pipelines 16 or 17 is injected alkaline or saline solution for creating reserve ions.

The use of bipolar membranes is known to the average expert in the field of electrodialysis.

In the case of a preferred practical example of the neutralization of herbicide ANITENRthat consists of a mixture of 2-(4-chloro-o-tolyloxy)-propionic acid, 3,5-diid-4-hydroxybenzonitrile and 3,5-dibromo-4-hydroxybenzonitrile in a weight ratio of about 5: 1:1, in the Central chamber 1 is injected aqueous solution of this mixture of substances with a concentration of about 525 g/l

Ionization reaches the easiest way with the help of the apparatus, which corresponds to the x-ray apparatus for the original medical purposes, which seized intended for shielding the rays of the aluminum plate.

Needless to say, should observe the necessary measures of protection against radiation according to the prior art OVE-regulations for the functioning of the installation.

The installation preferably operates continuously, and through the chamber 1, the solution of the raw material flows with a speed of 17 l/h.

Solution in analtoy chamber 7, which consists of demineralized water with 1% chemically pure NaOH and prior experience absolutely no chlorine, already after 2 minutes duration of experience imedea content of halogen in the solution is preferably carried out spectrophotometrically by.

If the specified continuous implementation of the method according to the pipes 16 and 17 serves sodium hydroxide solution with a concentration of 8 wt.% or 4 wt. %.

Anality and natality solution is continuously replaced by filing a solution of caustic soda at a concentration of about 8 wt.% in the amount of approximately NaOH: halogen = 1:1.

As shown in this figure, the device for dialysis is preferably a multi-chamber device. In certain cases, however, can also be quite simple devices for dialysis with only one camera.

Preferably the device for dialysis has at least one bipolar membrane.

Dialysis shown in Fig. 1 the device was carried out at a voltage of 30-200 Century When the electric energy in the amount of about 21 watts per kg of the treated fluid.

In the practical implementation of the method ionization and the dialysis is conducted preferably under pressure.

Instead of filing caustic soda is possible to carry out the supply of salt solution, a solution, for example sodium.

In Fig. 2 now presents the entire installation, which contains a device for ionization and taught the mixture of raw materials from the tank 20 through the pipe 21, which provides the necessary pumps and valves.

By ionizing device 22 in part II for ionization recyclable substance is cleaved and separated in a device for dialysis.

Part III for dialysis shows that, of the device for dialysis 23 through line 24 carry out the unloading of organic matter in the form of dilute, while through the loops 25 and 26 are unloading inorganic reaction products in the form of a concentrate. In order for you to take the pipes 27 and 28, the pipes 29 and 30, depending on the circumstances, you need to enter an alkaline or saline.

Incompletely reacted solutions can be recycled in the method.

In Fig. 3 presents an even more improved multi-chamber system in the schematic diagram of the functioning. See the principle of the flow of ions that occurs in the setting. Together with a solution of raw materials in the installation again can return the recirculated part diluate, if processing has not passed completely.

Between the anode 1 and cathode 2' are membrane 3'-8', and membrane 3', 5' and 7' is a cathode membrane and the membrane 4', 6' and 8 Atria. The pipeline 11' as initial solution serves aqueous salt solution (e.g., NaCl, Na2SO4or alkaline solution (e.g., NaOH), which circulate through the respective chamber, the pipes 13', 15' and 17' assign concentrate.

In the case of a 12' serves the solution utilized aliphatic kalogeropoulou - FCKW, insecticide or herbicide. Deloit divert pipeline 14', 16' or return in 12'.
