Description

The invention relates to a method for mass preparation, processing and recycling of spray cans and the remaining ingredients contained therein, and a device and apparatus for carrying out the method. In which the spray can be emptied without deformation-destruction and collected the ingredients and collected in separate containers.

The statistics say: At the end of the 20th century, spray cans became a huge market. In Europe 4.5 billion spray cans are produced annually, in Germany alone there are more than 950 million. In cosmetic and chemical industries, production has doubled every 5 years. These are understood spray devices with a filling of liquid, mushy, or powdery substances that are under pressure of a propellant. The proportion of liquid propellant gases in spray cans is between 6% and 12%. The spray cans of very different shape and size are equipped with a valve cover of the same standard shape and size: namely 030 mm, which allow the removal of the content as a mist, aerosol, smoke, foam powder, paste, or liquid jet.

The propellants used are CFCs (fluoro-chloro-hydrocarbons-freon 12, which is banned by Montreal's protocol), propane, butane, isobutane, nitrogen or the like. Spray cans of various degrees of filling accumulate as waste and are currently stored mainly as hazardous waste, after the rotting of the can material, usually tinplate or aluminum, the propellant gases and liquid hydrocarbons (abstain from spray cans) can escape. A large number of spray cans can also be found in waste incineration plants. When burning the cans explode.

These explosions are feared by the operators of waste incinerators, as they can cause severe damage inside the kilns.

Another problem is the return of spray cans, which are still partially filled because their content could not be completely consumed (eg, do-it-yourselfers) or whose expiration date is exceeded, so that the effect of the content is no longer guaranteed , These, in itself still usable substances containing the spray cans, were essentially "disposed of" only by landfilling.

For some of the DE 3837656 A1 . DE 3713477 C1 . DE 4204836 C2 . DE 1970460 A1 known methods, devices and apparatus, the spray cans are subjected to overpressure and vacuum. In this method, the following deformations destructions are carried out as, destruction of spray cans, mixing the contents of the spray can with large amount of water. That you have to produce multi-stage distillate afterwards. Then the destroyed bodies are crushed by spray cans and sorted into metal-rubber-plastic.

• 1. Im ruhigen Zustand befinden sich die Substanzen einer Spraydose in Schichten, in einem zerlegten Zustand. In dem unteren Bereich einer Spraydosen Sohle befinden sich die Feststoffe, in dem mittleren Bereich die flüssigen Substanze, und in der oberer Schicht die flüssigen und gasförmigen Gastriebmitteln.
• 2. Bei Beaufschlagung von Spraydosen, so wie bei Erschütterungen des Inhaltes in der Spraydose, verwandelt sich die ganze Substanz zur einen Suspension-Emulsionsmischung. Bei Fremdeinwirkungen, wie Zerstörung, oder Beschädigung von Dosenkörpern mit dieser Suspension-Emulsionsmischung, verwandelt es sich in Sekunden zu einem Aerosolwölkchen und verdampft in Sekunden. Aber wenn dieser gasförmige Kohlenwasserstoff sich mit der Atmosphärenluft im Verhältnis von 3–78% verbindet, entsteht ein gasförmiger Sprengstoff. Wird dieser Temperatur, Kohlendioxid und ultravioletten Strahlen ausgesetzt, zerlegt sich die Kohlenwasserstoffe bis zum niedrigstem Form, Gas Methan. Das ist einer der Ursachen, die zur Klimawandlung führen.
• 3. ECON-AIR Aerosol und Chemierecyclingtechnologie AG – war die einzige Firma, die Spraydosen wiederverwertet hat. Durch die oben genannte Mängel und Verfahrensfehler ist die Firma ECON-AIR im Jahr 2000 explodiert und vollkommen ausbrannte. Nach der Pleite von ECON-AIR im Jahr 2002, wurden die ganzen Räume, Technologien und Markenrechte von der Firmengruppe „TUNAP” übernommen. TUNAP Industrie Chemie GmbH & Co. Produktions-KG. Mit dem Problem vom Aerosol in Spraydosen und dessen Wiederverwertung beschäftigt sich niemand.

These methods are not only unprofitable, but also very complicated and expensive. The loss of content at every stage of the process damages the environment. At first glance it seems that the danger of an explosion, or a fire is already pre-programmed and there is a procedural error:

• 1. In the calm state, the substances of a spray can are in layers, in a disassembled state. In the lower part of a spray can sole there are the solids, in the central region the liquid substance, and in the upper layer the liquid and gaseous gas propellants.
• 2. When aerosols are applied, such as when the contents in the spray can become agitated, the whole substance is transformed into a suspension-emulsion mixture. In the event of external influences, such as destruction or damage to can bodies with this suspension-emulsion mixture, it turns into an aerosol cloud in seconds and evaporates in seconds. But when this gaseous hydrocarbon combines with the atmospheric air in the ratio of 3-78%, creating a gaseous explosive. When exposed to this temperature, carbon dioxide and ultraviolet rays, the hydrocarbons decompose to the lowest form, gas methane. That's one of the causes that lead to climate change.
• 3. ECON-AIR Aerosol and Chemical Recycling Technology AG - was the only company to recycle aerosol cans. Due to the above-mentioned defects and procedural errors, the company ECON-AIR exploded in 2000 and completely burned out. After the bankruptcy of ECON-AIR in 2002, all the rooms, technologies and trademarks were taken over by the TUNAP group of companies. TUNAP Industrial Chemistry GmbH & Co. Produktions-KG. Nobody deals with the problem of aerosol in spray cans and their recycling.

It is an object of the present invention to provide a method and apparatus for mass disposal of solid and liquid substances, as well as aerosol cans containing liquefied and gaseous propellants, whereby the use of only mechanical devices for opening the spray cans is a simple, economical and low-maintenance Interpretation is possible.

This object is achieved in that the spray cans placed on the preparation stage in a specially designed box (drawing insert no. 1) and are fixed there by removable blanket sole, characterized in that the spray can from a foreign influence such. As deformation, damage, destruction in each process step, such as disposal or treatment are protected.

In the adjacent process, which is used for the mass preparation, processing and recycling of spray cans, the boxes of charged aerosols of certain types (water-soluble or solvent-soluble) into the chain link mounts II (Drawing supplement no. 2). The chain conveyor consists of chain link holders, where the boxes are fixed with semi-automatic closure, thus the box is attached. A special feature of the construction of the chain conveyor is that the chain link bracket with semi-automatic closure allows the box to turn 180 ° and the chain conveyor bends 90 ° and 180 °, characterized in that a box-by-tray emptying and cleaning of spray cans, in a closed space -Überdruckkammer V (Drawing Enclosure No. 3) is executed.

Hyperbaric chamber V is sensed with inert gas nitrogen. It is equipped with advantageous devices and equipment to perform a four-step process can.

Stage 1: Through a liftable and sinkable block mechanism for opening spray cans (OM), the removal of valve mechanism blankets of spray cans in the box takes place. The spray cans are opened and the cooled contents become accessible. (Explanation: when liquid gas propellant exits the spray can, it vaporizes and deprives the environment of heat.)

As already explained above, the conditioning operations are a slow and quiet movement of the chain conveyor, in which a chain link is moved within 2-3 seconds. Without shocks and impositions the content remains in layers decomposed state. Information desk: Gas propellant of spray can Dense liquid C3H8 - Propane 0.578 g / ml C4H10 - butane 0.579 g / ml Liquid substance of spray cans Dense liquid CH3OH - methanol 0.79 g / ml CH3CH2OH - ethanol 0.79 g / ml CH3CH 2CH2OH - propanol 0.80 g / ml CH3 (CH2) 2CH2OH - butanol 0.81 g / ml H2O - water 1.00 g / ml

According to these chemical and physical properties of liquefied and liquid substances in the contents of a spray can, they are together insoluble. In quiet conditions, the substances always remain in layers decomposed state. After the separation of liquefied gas propellant from the contents of the can, the conversion of substances into aerosol or foamy state is excluded.

Stage 2: By turning the box by 180 ° (WM-1), the crate is tilted 180 ° and the liquid substances are poured into a receptacle (K2)

Step 3: Lifting and descending sprinkler system between the sump (K3) and the tilted crate shroud holder are required for cleaning and flushing the empty aerosol cans.

Uniform box and a block-opening mechanism, but consisting of 35 spray nozzles with a separate drain. The cleaning fluid is circulated: pump, filter, high-pressure cleaner, sprinkler system, drain, collecting tank (K3).

Stage 4: The turning mechanism (WM2) places the box in the first position as in the step before exiting the box on the chain conveyor II through hydronic pool IV so that then emptied and cleaned spray cans are sunk into the water. Since the box with cans is rinsed again and at the same time the remaining gas products are displaced.

The entire system is only operated by low power consumption (about 50 KW), which meets the requirements for environmental protection and safety regulations. For small changes in the system and the devices you can also use the system for other purposes such. Such as: to defuse chemical weapons, ammunition and the disposal of their contents in prescribed containers. As well as the conflict of refrigerants from old, defective, outdated refrigerators, such as air conditioners based on (Freon-12, butane, propane).
