Description

[0001] DESCRIPTION

[0002] Inerting tank for the safe transport and / or storage of metal phosphide waste

[0003] OBJECT OF THE INVENTION

[0004] The invention, as expressed in the title of this specification, relates to an inerting tank for the safe transport and / or storage of metal phosphide waste that provides advantages and features, which are described in detail below.

[0005] The object of the present invention lies in a deposit that aims to provide a transport and storage system for metallic phosphide waste, specifically aluminium or magnesium, that is safe, that is, without emanations to the outside of Phosphine gas (PH3), as it is a highly toxic poisonous gas and which, in addition, in certain concentrations, is self-deflagrating and self-explosive on its own, without the need for any ignition source or fuel.

[0006] FIELD OF APPLICATION OF THE INVENTION

[0007] The field of application of the present invention falls within the chemical industry sector, especially that dedicated to the handling, transportation, storage and / or treatment of chemical waste, focusing particularly on the field of metal phosphide waste.

[0008] BACKGROUND OF THE INVENTION

[0009] Metal phosphides are chemical compounds containing phosphorus in combination with one or more metals. One of the best-known metal phosphides is aluminum or magnesium phosphide, but others also exist, such as zinc phosphide and calcium phosphide.

[0010] These compounds are primarily known for their use as fumigant pesticides used to protect stored goods, such as grains and food. Aluminum phosphide, for example, is used to fumigate enclosed spaces to control pests.

[0011] When metal phosphides come into contact with moist air or water, they release phosphine (PH3), a highly toxic gas. Phosphine is the active ingredient that acts as a pesticide in eliminating pests. However, the release of phosphine can also pose risks to human health and the environment due to its toxicity, flammability, and explosiveness.

[0012] The application of metal phosphides as fumigants results in chemical waste and toxic decomposition byproducts to generate phosphine gas.

[0013] Collecting or managing such metal phosphide waste safely and without accidents is difficult and risky. Due to its toxicity and danger, and the potential for deflagration or explosion, handling it irresponsibly or with inadequate means, it can cause accidents with personal injury, property damage, and environmental damage, and may result in fines or criminal charges.

[0014] However, there is currently no technical solution that completely resolves this problem. Managing this type of waste is extremely risky.

[0015] The objective of the present invention is, therefore, to provide a safe and practical means of inerting said waste in order to transport and store it without risk. It should be noted that, as a reference to the current state of the art, at least by the applicant, the existence of any other inerting tank or invention of similar application is unknown, which has technical, structural and constitutive characteristics equal to or similar to those claimed here.

[0016] EXPLANATION OF THE INVENTION

[0017] The inerting tank for the safe transport and / or storage of metal phosphide waste that the invention proposes is configured as an optimal solution to the objectives previously indicated, the characterizing details that make it possible and that distinguish it being conveniently included in the final claims that accompany this description.

[0018] Thus, basically, what the invention proposes, as previously indicated, is a tank that has the purpose of serving as a transport system and / or safe storage of metal phosphide waste, specifically aluminum or magnesium, for which it is configured from a container, suitable for housing the waste inside, which comprises:

[0019] • walls resistant to oxidizing agents,

[0020] • a lid that hermetically seals the container, and

[0021] • a communication duct from the inside of the container to the outside located in the upper part of the container that comprises a filter that traps phosphines in such a way that cryogenic freezing of metal phosphide residues inside the container (2) is possible, either by the injection of Liquefied CO2 gas (LCO2) or by the addition of carbon ice (dry ice) and that the gas released inside the container can be expelled to the outside through the communication duct after being neutralized by the filter.

[0022] In a preferred embodiment, the container comprises inside Carbonic ice (derived from the dry ice supplied) or carbonic snow derived from the injection of Liquefied CO2 gas - LCO2, through at least one valve in the container such that the metal phosphide residues are kept below -72°C.

[0023] When the carbonic ice or carbonic snow injected through the container valve sublimates, it generates a carbonic atmosphere that displaces the oxygen contained in the air of the container, once the lid is closed, and thanks to the filter provided in the communication duct between the interior of the container (2) and the exterior located in the upper part of the container (2), the gas forces said oxygen out through it, whereby it is automatically neutralized by the activated carbon, obtaining a residue inside that no longer deflagrates or is explosive and, therefore, can be stored or transported with complete safety.

[0024] The traces, which may form while the dry ice acts, rise upwards due to the effect of the carbon dioxide and are retained by the filter. In a preferred embodiment of the invention, the container is an isothermal container, specifically a container with a valve for gas injection, and a communication conduit from the interior of the container to the exterior located in the upper part of the container (2) that comprises a filter that traps the Phosphine gas (PH3), such as an activated carbon or zeolite filter.

[0025] Alternatively, the same effect would be possible with an insulated container containing a series of dry ice pellets (carbon dioxide ice) that freeze the residue. In this case, it should be noted that dry ice thaws over approximately two days and loses its freezing capacity.

[0026] Optionally, the container includes a bag, preferably isothermal and made of fireproof fabric, for placing and extracting the metal phosphide waste, and includes conduits with diffusers that connect to the gas injection valve to distribute the gas to the waste contained in the bag.

[0027] Optionally, a basket is included inside the container, preferably made of mesh or perforated sheet of stainless steel or aluminum, to carry the metal phosphide waste [AIP] or [MgsP2] for which the tank is intended from the outside to the inside of the tank, as well as to extract them once transported to the destination.

[0028] The basket also allows carbon ice (derived from dry ice supplied) or carbon snow derived from the injection of liquefied CO2 gas - LCO2 to pass through to the metal phosphide waste.

[0029] If the container comprises a sack, in a preferred embodiment, the sack includes conduits with diffusers distributed throughout its walls and connected to the container's valve for injecting a gas, such as liquefied CO2 (LCO2) gas, to generate dry ice. In this embodiment, and when the metal phosphide waste is contained within a basket, it is advantageous for the dry ice generated within the sack to be able to pass through the basket and surround the metal phosphide waste, ensuring that it freezes. In one embodiment, the sack is provided with attachments to the container.

[0030] In one embodiment, the bag is provided to comprise a lid of the same material with Velcro-type closing means.

[0031] For its part, the communication conduit from the interior of the container to the exterior located at the top of the container preferably comprises an upper non-return valve that prevents the entry of fluids from the outside into the interior of the container.

[0032] The filter that traps Phosphine gas (PH3) preferably comprises a coil through which the gas inside the container passes before being released to the outside.

[0033] In one embodiment, the container comprises a moisture-proof chamber incorporating a desiccant filler.

[0034] In one embodiment, the container comprises a spill-proof chamber with gelling material.

[0035] In one embodiment, the container may incorporate sensors, at least for identification, geolocation and temperature measurement, to control the conditions and location of the waste during transport.

[0036] The container can have different configurations and sizes. For example, in one embodiment, the container is envisioned as a transportable container or drum, while in another, the container may be a room or warehouse.

[0037] In an alternative embodiment, the container of the invention may be a drum with a lid, preferably cylindrical, or a room, in any case made up of walls with several layers of specific materials that have a lid or a door that closes it hermetically and a system of valves and conduits to inject a gas with a density greater than 1.38 Kg / m 3, (density of phosphine gas), said gas preferably being carbon dioxide. Specifically, in this embodiment, the tank comprises at least one valve connecting the exterior with the interior of the container and allowing the gas to be injected into the container, and a valve at the top of the tank connecting the interior with the exterior of the container and allowing the gas to be extracted through it.

[0038] To this end, in a preferred embodiment, the container has the following parts and elements:

[0039] - An insulating layer that covers the metal walls of the container and the lid internally.

[0040] - Two conduits integrated into the insulating layer of the container such that one end is connected to a side non-return valve, accessible from the outside for the injection of carbon dioxide, and the opposite end is connected, in a first conduit to a freezing mechanism that operates thanks to said gas, and in the second conduit it is directed towards the interior of the container to fill it with gas.

[0041] - An “anti-humidity” chamber that incorporates granulated anhydrous calcium chloride.

[0042] - A spill-proof chamber with gelling material located at the base of the container.

[0043] - And a sealed collector integrated into the lid with a coil that connects the interior of the container when the lid is in the closed position with the exterior through a non-return valve, such that, when carbon dioxide is injected through the second conduit and the interior of the container where the waste will have been placed is filled, it then passes through the coil and exits to the outside.

[0044] More specifically, the entire interior of the container and the closing lid are heat-treated with a layer of fireproof polyurethane insulation, which, in turn, is protected externally by a layer of metal, stainless steel or aluminum, which forms the walls of the tank.

[0045] In addition, the container includes two ducts that have been integrated into the walls of the tank, in the process of constructing the "heat-insulating" layer, so that they are located one on each side of the container.

[0046] These ducts serve as a circuit for the injection of carbon dioxide gas [CO2], their routes being as follows: In a first duct: One end starts from a non-return valve, incorporated in the side wall of the container, and its other end is oriented towards the lower base of the container, adjusting to a freezing mechanism, preferably a “freezing bag” located in a space provided in said base between the insulating layer and the internal layer of perforated sheet metal.

[0047] And in a second conduit: One end starts from another non-return valve placed on the side wall of the container, in this case at 180°, that is, on the diametrically opposite wall and at the same height as the valve of the first conduit, and its other end is oriented towards the base of the container, leaving it with a free outlet towards the interior of the tank and protected by a grid.

[0048] Furthermore, superimposed internally on the heat-insulated polyurethane layer and for the entire container, including its opening lid, there is a moisture-proof or "sequestering" chamber, for which said chamber is constructed with perforated sheet of stainless steel or aluminum and incorporates a filling of granulated anhydrous calcium chloride [CaCh].

[0049] Also, at the base of the container, above the moisture-binding chamber, is a spill-proof chamber. This chamber is preferably also protected by a perforated wall of stainless steel or aluminum. Inside this wall of the spill-proof chamber is a fireproof fabric bag filled with sodium polyacrylate [CH2CH(CβNa)], a compound that will gel aqueous liquids that may be released from the waste due to weather or condensation.

[0050] On the other hand, a sealed collector is installed in the closing lid of the container, specifically at its base, consisting of a perforated ring of stainless steel or aluminum, inside which a coil is housed that has its inlet end on one side of the lid, such that it is open to the interior of the container when the lid is in the closed position, and at its opposite end it flows to the outside through a non-return valve centered on the surface of said lid.

[0051] This duct or coil contains sodium hypochlorite [NaOCI] and activated carbon [C] as decomposition and adsorption agents of any phosphine gas [PH3] that may be produced.

[0052] Thus, the mode of use of the tank object of the invention comprises some of the following steps:

[0053] For deposit preparation:

[0054] - The anti-humidity chambers are filled with granulated anhydrous calcium chloride [CaCh].

[0055] - The lid coil is filled with absorbents, sodium hypochlorite [NaOCI] and activated carbon [C].

[0056] - Carbon dioxide [CO2] is introduced at high pressure through the side valve of the first conduit to form dry ice in the freezing bag located at the base of the container.

[0057] - The fireproof fabric bag with a sodium polyacrylate filling [ — CH2CH(CC>2Na) — ] is introduced into the spill chamber.

[0058] - The container is closed with its lid, which preferably has a spring lock to ensure airtightness.

[0059] - Carbon dioxide [CO2] is introduced at a pressure of 1 BAR through the side valve of the second conduit and the complete filling of the interior of the container with carbon dioxide [CO2] is ensured, checking the exit of carbon dioxide [CO2] gas through the non-return valve located in the upper part of the center of the lid.

[0060] To load the tank:

[0061] - The container is opened without tipping it over.

[0062] - The basket is removed from inside the container by raising it perpendicular to the ground.

[0063] - The basket is filled with the phosphide residue.

[0064] - Slowly and carefully insert the basket into the container, also perpendicular to the ground.

[0065] - The container is closed with its lid.

[0066] - Carbon dioxide [CO2] is introduced at a pressure of 1 bar through the second conduit and the complete filling of the container's interior is ensured by checking the carbon dioxide [CO2] outlet through the top non-return valve in the center of the lid. - It is transported to its destination.

[0067] To unload the tank once it has been transported to its destination:

[0068] - Carbon dioxide [CO2] is introduced again at a pressure of 1 BAR through the second conduit and the complete filling of the interior of the container with said carbon dioxide [CO2] gas is ensured by checking the exit of carbon dioxide [CO2] gas through the upper non-return valve in the center of the lid.

[0069] - The container lid is opened without tipping it over.

[0070] - Remove the basket with the waste from inside the container, raising it perpendicular to the ground.

[0071] - The basket is emptied with the phosphide residue.

[0072] - The empty basket is placed back inside the container.

[0073] - The container is closed with its lid.

[0074] - Since the container contains traces of the phosphide residue from the transported waste and its phosphine gas; for safety, once the empty container is closed, carbon dioxide [CO2] is reintroduced at a pressure of 1 BAR through the second conduit and the complete filling of the interior of the container with said carbon dioxide [CO2] gas is ensured by checking the exit of carbon dioxide [CO2] gas through the upper non-return valve in the center of the lid.

[0075] - Finally, the tank is stored or transported to another destination to collect more waste.

[0076] The advantages of the tank object of the invention are multiple, especially the following:

[0077] - It is built with robust materials that are physically and chemically unalterable.

[0078] - It has low mechanical maintenance.

[0079] - The contents are protected from the elements.

[0080] - Does not generate unhealthy gases.

[0081] - No electrical support machinery required.

[0082] - Functional in maritime or land situations.

[0083] - Safety period of more than 5 days and easily extendable. - Transportable by any sea or land means.

[0084] - High storage capacity.

[0085] - Easy and quick to clean.

[0086] - Safe storage without accidents.

[0087] - Easy handling.

[0096] PREFERRED EMBODIMENT OF THE INVENTION

[0097] In view of the aforementioned figures, and in accordance with the adopted numbering, one can observe in them a non-limiting embodiment of the inerting tank for the safe transport and / or storage of metal phosphide waste of the invention, which comprises what is described in detail below.

[0098] Thus, as observed in the above, the tank (1) of the invention is configured from a heat-sensitive container (2) comprising

[0099] • walls (5) resistant to oxidizing agents,

[0100] • a lid that hermetically seals the container, and

[0101] • a communication duct from the inside of the container (2) to the outside located in the upper part of the container (2) comprising a filter that traps Phosphine gas (PH3) in such a way that cryogenic freezing of metal phosphide waste is possible inside the container (2) either by the injection of Liquefied CO2 gas (LCO2) or by the addition of carbon ice (dry ice) and that the gas released inside the container can be expelled to the outside through the communication duct after being neutralized by the filter.with hermetic closing means that, made of walls (5) resistant to oxidizing agents In a preferred embodiment of the invention, such as that shown in figures 5 and 6, intended to carry out the inertization of the waste by cryofreezing at -72 ° C, the container (2) is an isothermal container comprising a non-return valve (9) for the injection of gas, as well as an upper gas outlet duct, with the non-return valve (20), provided with a filter (29), through which the flow will pass before exiting through said valve. The container comprises a lid (3) preferably with a high resistance sealing gasket (26), viton type, and safety closure (27) to guarantee the hermetization of the container (2).

[0102] Optionally, the container (2) can incorporate sensors (28), at least, for identification, geolocation and temperature measurement, to control the conditions and location of the waste during transport.

[0103] Furthermore, inside the container (2) there is a bag (22), preferably isothermal and made of fireproof fabric, to place and extract the metal phosphide residues.

[0104] The bag (22) includes, coupled to its walls, the ducts (7) with diffusers (23) distributed throughout it which, connected to the valve (9) of the container (2) or directly to the source of the liquefied gas (LCO2), allow the liquefied gas (LCO2) to be distributed to the waste, wrapping it directly so that it remains cryofrozen.

[0105] In any case, preferably, the bag (22) has a lid made of the same material with a sailboat-type closing means (25) to close the waste inside.

[0106] For its part, looking at figures 1 to 4, it can be seen how, in another embodiment, intended for inertization of the waste by means of cold transfer, the container (2) forming the deposit (1) of the invention is a metal container, preferably cylindrical, which has a top closing lid (3) which, for example, by means of a spring closure (4), closes it hermetically, and essentially has the following particularities:

[0107] Both the container (2) and the lid (3) are made with metallic external walls (5), made of steel with anti-corrosion surface treatment, stainless steel or aluminum, and internally incorporate a heat-insulating layer (6) of fireproof polyurethane.

[0108] Integrated into the aforementioned insulating layer (6), the container (2) comprises two conduits (7 and 8) which, located on opposite sides of the side walls thereof, serve as a circuit for the injection of carbon dioxide gas [CO2] into the tank. Specifically, a first conduit (7) extends from an upper end (7a), where it is connected to a side non-return valve (9), incorporated in the side wall of the container (2) so that it is accessible from the outside for the injection of the gas, to its opposite end (7b) located internally and oriented towards the center of the lower base (2a) of the container (2), where it is connected to a freezing mechanism (10), preferably a freezing bag, located in a hollow space (11) provided in said lower base (2a) between the insulating layer (6) and another internal layer described later, to form dry ice when applying the carbon dioxide gas.

[0109] And a second conduit (8) extends from an upper end (8a), where it is connected to another lateral non-return valve (9), incorporated in the lateral wall of the container (2) on the diametrically opposite side and at the same height as the valve (9) of the first conduit (7), so that it is also accessible from the outside for the injection of gas, to its opposite end (8b) located internally, also at the base (2a) of the container (2), in this case with an outlet towards the interior of the same and protected by a grid (12) so that when injecting carbon dioxide at a pressure of 1 bar, it penetrates the interior of the container (2).

[0110] Furthermore, superimposed internally on the heat-insulating layer (6) of polyurethane, both in the container (2) and in the lid (3), the existence of a humidity "sequestering" chamber or anti-humidity chamber (13) is foreseen. Said anti-humidity chamber (13) is constructed with perforated sheet of stainless steel or aluminum and its interior incorporates a filling of desiccant material (14) of granulated anhydrous calcium chloride.

[0111] Likewise, on the part of the aforementioned anti-humidity chamber (13) that covers the base (2a) of the container (2), there is located an anti-spill chamber (15). This anti-spill chamber (15) is defined and protected, at least superiorly, by a perforated wall of stainless steel or aluminum and inside it is housed a fireproof fabric bag with a filling of gelling material (16) of sodium polyacrylate, which will gel the aqueous liquids that may come from the waste due to the weather or condensation. Preferably, the wall of the anti-spill chamber (15) is removable to be able to put and take out said bag of gelling material (16).Furthermore, inside the container (2), instead of a bag, the existence of a basket (17) is contemplated, preferably made of mesh or perforated sheet of stainless steel or aluminum, to place and extract the metal phosphide waste while allowing the Carbonic ice (derived from the dry ice supplied) or carbonic snow derived from the injection of Liquefied CO2 gas - LCO2 to pass towards the metal phosphide waste.

[0112] To facilitate said removal and placement, the basket (17) has one or two holding handles (17a) on its upper part.

[0113] For its part, in the closing lid (3) of the container (2), specifically in the base thereof, a sealed collector has been provided formed by a perforated ring (18) of stainless steel or aluminum, inside which houses a coil (19) that has its inlet end (19a) on one side of the same that faces the interior of the container (2) when the lid (3) is in the closed position, and at its opposite end (19b) it flows to the outside through an upper non-return valve (20) located in the central part of the surface of the lid (3), such that, when carbon dioxide is injected at a pressure of 1 bar through the second conduit (8) and the interior of the container (2) is filled, it passes through the coil (19) penetrating through the lateral inlet (19a) of the lid (3) and exiting to the outside through said upper valve (20).

[0114] In addition, this coil (19) contains sodium hypochlorite and activated carbon as filtering agents for the decomposition and adsorption of any phosphine gas that may be produced.

[0115] Preferably, the container (2) has handles (21) on the sides to facilitate handling and transport.

[0116] It should be noted that both examples of the tank (1) described are only examples of embodiment, as shown in figures 5 and 6, or in figures 1 to 4, that is, where the container (2) is a transportable container or drum with an upper lid (3) as a closing means, this being a preferred option as a tank for transporting metal phosphide waste, although it should be understood that it can also have other shapes and, for example, be larger and consist of a room or bedroom, in which case the closing means can be a door or similar and be designed as a tank for storing waste.In any case, the device is configured from a container (2) with means of hermetic opening and closing which, made of walls (5) resistant to oxidizing agents, will comprise, at least, the non-return valve (9) that connects the exterior with the interior of the container (2) and allows the injection of a fluid with a density greater than 1.38 Kg / m3 (which is the density of phosphine) inside the container (2), said injected fluid preferably being carbon dioxide gas, and the upper non-return valve (20) in the upper part of the container (2) that connects the interior with the exterior of the container (2) and allows the extraction of a fluid through it.

[0117] Furthermore, preferably, the container (2) is isothermal and comprises an insulating layer (6) and a filter before the outlet of the upper non-return valve (20).

[0118] The rest of the elements are optional, that is, the anti-humidity chamber (13) with desiccant filling (14), internally superimposed on the insulating layer (6) and, preferably, the anti-spill chamber (15) with gelling material (16).

[0119] Furthermore, the container (2) comprises, also as an optional element, the coil (19) before or after the upper non-return valve (20), and preferably, the gas collector with the coil (19) oriented so that it communicates the interior of the container (2) with the exterior through the upper non-return valve (20).

[0120] Having sufficiently described the nature of the present invention, as well as the manner of putting it into practice, it is not considered necessary to make its explanation more extensive so that any expert in the field understands its scope and the advantages derived from it.
