Abstract
The present invention is directed to a process for inflating an inflatable object, comprising providing a gas having a temperature of at most 100 °C, by using the endothermal decomposition of a product made of gas penetrable solid material.
Description
Title: Process for inflating an object
The invention relates to applied chemistry, more specifically to the generation of gases of low temperature for inflating objects.
Inflation of inflatable objects, such as airbags for cars, rafts, life boats and vests, fast installed partitions (which are used in well drifts to cut off the well in case of fire) and the like, is a very common phenomenon.
Usually the systems for inflating objects are either based on compressed gases stored in cylinders, or on compressors driven by external power, such as gasoline or electricity. The latter approach is not useful in case the inflation has to occur on locations where such facilities are not available. Examples thereof can be found in all kinds of emergency systems, rescue and salvage systems and the like. Also the use of compressed gas has disadvantages, as these systems require maintenance and cannot be relied on in situations where only occasionally need exists for its use. Further, the use of compressed gases may have the disadvantage of temperature decrease due to adiabatic expansion. Especially when relatively large amounts of gas are expanded to low pressure, temperatures may drop to -50°C, with the result of icing-up, or even blocking the opening by freezing.
The weight and size of the system for providing the gas for power generation is also an important consideration. Gas generating processes based on the decomposition or burning of chemical propellants and other compositions are frequently being used for a number of purposes. It is known that gas for inflation can be generated by decomposition or burning of solid materials, such as azides. However, these materials have the disadvantage that they generate a very hot gas, which is often unwanted, because of the hazards thereof to the environment or the object to be inflated.
Accordingly there is a need for a system for inflating inflatable objects, which system is reliable, does not require maintenance, and that can be used in isolated situations, without the need for external supervision. Further, such a system should be generating gas of a relatively low
temperature, which is preferably not harmful to the environment.
The present invention is based on the use of a generator of cold gas by using the endothermal decomposition of a product made of gas penetrable solid material. The invention accordingly provides for a process for inflating an inflatable object, comprising providing a gas having a temperature of at most 100°C, by using the endothermal decomposition of a product made of gas penetrable solid material.
The hot gas generated by the burning of a solid material passes through the porous material. The heat of decomposition needed is given off by the hot gas, which cools as a consequence thereof.
The cooling can be effected by an endothermal reaction, or of a phase transition of the solid porous material. Examples of phase transition are melting, evaporation and sublimation. The present invention can be used especially for all kinds of inflation, that are carried out at difficult locations, such as in unpopulated areas, on sea or under the water, for rescue and salvage operations, and the like.
More in particular it is possible to use the invention for inflating all kinds of airbags (cars, trucks, helicopters, planes). These airbags can be side, roof or front located.
The invention can also be used for inflating objects that require floating properties, such as life-jackets, rafts, boats, slides (rescue from airplanes and the like), rescue boats or rescue systems for divers. Also in salvage operations of boats, ships, vessels or barges, the present invention may be applied. Salvage operations of other equipment, like training equipment on sea, meteorological equipment, satellites and the like, are also possible using the process of the present invention.
Other areas where the invention may be applied include inflating floats for bridges, tools, instruments and the like. Also in the lifting and removal of oil rigs, the present invention may be applied.
The invention can also be used in inflating tents and other objects, like lifting cushions, jumping cushions, and inflated copies of equipment for shows, decoys and the like. All these applications have in common that they require a relatively cold and harmless gas to be generated at short notice at locations where no
external power is available. Important in these applications is also that the equipment is relatively compact and remains reliable even after long periods of storage, without maintenance or testing. Especially the use of compressed gas requires continuous maintenance activities. For example in remote locations this may be difficult to arrange.
In the present invention a method of generating cold gases, specifically nitrogen, oxygen, hydrogen, carbon dioxide or a gas-mixture containing at least one of these gases, is used, which method is based on the decomposition of a product made of gas penetrable solid material. The gas penetratable solid material (porous body) comprises a nitrogen (or other gas) source and a heat absorbing mixture, whereby the gaseous reaction products are cooled by passing the hot gases through the said porous body of the product in the moving direction of the reaction front. The hot gases heat the porous body to a temperature necessary to support the endothermic chemical reaction taking place. The heating of the porous body is necessary to enable the main reaction. The decomposition of the cooling agent is also an endothermic chemical reaction.
The type of gas generating material can be freely selected among the suitable propellant or other gas generating materials. Generally the gas to be generated will be nitrogen, but it is also possible to use oxygen, hydrogen, carbon dioxide or a suitable mixture containing at least one of these gases.
The high temperature burning gases are passed through the layer of the cooling agent or the heat exchanger and the temperature of the gases decreases as a result of the endothermal decomposition process of, or heat absorption by the cooling agent.
The degree of cooling of the generated gas depends on the nature of the cooling agent, the mass of the cooling agent, which can sometimes exceeds the mass of the gas-generating composition. Generally the gas is cooled to a temperature below 100°C, but a value within the range of 25 to 75°C is preferred.
When sodium compounds are used as the gas source for the low temperature gas production, the decomposition reaction generally results in Na and the gas. The formed gas is blown off and the slag remains. This slag comprises of the remains of cementing agent and cooling agent and metallic sodium. Under these conditions of gas generation the highly chemically reactive sodium is thus generated. This highly reactive material will
accumulate in the condensed burning products and thus provides a potential hazard for persons involved. When moisture is present this can result in vigorous and dangerous reactions taking place in combination with the generation of the highly flammable and explosive hydrogen. According to a preferred embodiment this problem can easily be overcome by the use of a gas generator comprising a first body, comprising means for the generation of gas, and a second body, comprising means for the generation of a neutralisation agent, wherein means are present for contacting the neutralisation agent with the reaction products formed in the generation of gas in the first body, and wherein means are present for operating the means in the second body at a temporal and/or spatial interval with the means in the first body.
The principle encompasses two gas generators in one housing. A first gas generator with the primary task of generating gas of low temperature, and a second gas generator with the primary task of generating neutralising compounds for the slag obtained from the first gas generator.
The first gas generator contains a composition from which gas of low temperature can be obtained by the decomposition of a gas generating composition in the form of a gas penetrable solid material wherein the generated gaseous products are passed through the porous body in the moving direction of the reaction front.
The second gas generator (the neutraliser) is another composition, comprising a gas generating composition together with an effective neutraliser compound, for instance sulphur. With the neutraliser composition gas and vaporised sulphur is generated at a time and space interval with the first gas generator. The gas and vaporised sulphur is generated at a rate and a manner that the effective neutralisation of slag is accomplished and the vaporised sulphur is not emitted. The vaporised sulphur reacts with the reaction products from the first gas generator such that the products are effectively neutralised.
The first and second gas generator do not have to be physically separated from each other. In embodiments of the invention they can be placed in any position relative to each other, as long as the vaporised neutraliser of the second generator can come into contact with the slag from the first generator.
The neutralisation takes place behind the reaction front of the decomposition reaction of the first gas generator. The spatial interval between the said reaction front of the first gas generator and production of the neutralising agent in the second gas generator is such that the reaction products of high temperature from the first gas generator stay behind, while the nitrogen gas is blown off. The neutralisation front lags behind the decomposition front and neutralises the said reaction products remaining behind.
In another embodiment of the invention the rate at which the gas generating composition decomposes is different from the decomposition rate of the neutraliser charge. Thus, the decomposition of the gas generating composition and the neutraliser are started simultaneously. Metallic slag is formed, followed by the generation of vaporous neutraliser in the second generator, which neutralises the slag. In another embodiment of the invention the moment at which the neutraliser is activated lies later than the moment of activation of the gas generator.
The activation, or ignition, of the two bodies can be done by any suitable means known in the art.
