本発明は、触媒基板上で作用しかつ水素を安全目的でガス混合物から除去する
ための装置に関する。The invention relates to a device for acting on a catalytic substrate and for removing hydrogen from a gas mixture for safety purposes.

設備自体を損傷し得る。The danger of hydrogen leakage occurs after the occurrence of an accident in various installations with energy and process technology. The presence of oxygen then creates a flammable gas mixture which can result in a violent deflagration or explosion. The pressure waves generated during an explosion can damage the equipment components or the equipment itself.

Hydrogen is generated in this reactor (LWR) in the event of failure of the associated safety equipment and in overheating of the core due to the reaction of the skin of the combustion elements with steam. In large LWRs, up to approximately 20,000 M N 3 of hydrogen or pollutants can be released in the safety tank in a few hours.

また、水素の除去のための効果的な方策を必要とする。As another example, a facility accident is said to be producing and treating hydrogen within the facility. Failures can likewise occur in future heat-generating and power-generating and hydrogen-operated systems, such as catalytic burners or fuel cells for stationary and moving areas.
In this system, generation and release of a small amount of hydrogen are also taken into consideration by the electrolysis method in standard operation when the battery is operated or ultrapure water is generated. This also requires effective measures for the removal of hydrogen.

である。Both low amounts (normal operation) and high amounts (accidents) of hydrogen are controlled and converted within a wide concentration range in accordance with a good mixing with air or an air supply and the heat of reaction generated thereby is present. It is necessary for the mixture to be discharged without reaching the ignition temperature each time.

子炉工業の情報によれば、４０〜１００の再結合機によって、軽い事故の場合に
水素問題に遭遇し得ることが確実である。For such use, thermal recombiners and catalytic recombiners have been developed which convert hydrogen with atmospheric oxygen in water vapor. Preferably, the catalytic system is operated passively, i.e. without the control and supply of electric current, without heating and forced flow-through, otherwise availability is a concern. At present there are two concepts in Germany that have been documented for their potential use by many sources of evidence. Metallic films and granule packs additionally coated with platinum or palladium are used as substrates. Many film and granule packs--the granules are packed in a pack by a wire net--are arranged vertically and parallel to one another in a plate housing. The hydrogen / air mixture enters the housing downwards. The reaction is initiated on the surface coated with the catalyst. The mixture or reaction product overflows on the surface due to the thermal lift generated. No blower is present or required. Reactor industry information ensures that 40-100 recombiners may encounter hydrogen problems in the event of a minor accident.

めに爆燃若しくは爆発を伴う均一なガス位相反応に繋がり得る。Maximum reduction rates or thermal efficiencies are limited due to low heat emissions due to surface overflow and convection. Furthermore, the possibility of heat storage is low. Too much hydrogen can lead to overheating of the coated substrate, which may reach or exceed the ignition limit and thus lead to a homogeneous gas phase reaction with deflagration or explosion.

ムにおいて反応は不完全である。Despite the large free surface of the recombiner in which porous granule aggregates are used as the substrate, the effectiveness is clearly less than in other systems where flat films are utilized. The combustion gas / air mixture does not reach all the catalyst centers in case of overflow on the coated substrate. The reaction takes place only on the surface. Furthermore, the flow is laminar, i.e. there is little lateral exchange. Not all molecules reach the effective surface. This also applies to structures using plates or films. The reaction is incomplete in both systems.

と見られる。Emission of reaction heat from the system is fundamentally problematic. The evacuation is almost exclusively by convection from the solid surface to the side-by-side gas as well as heat radiation to adjacent structures. Due to the small construction height, the lift inside the recombination machine is small. The flow is laminar and therefore has a low thermal or mass transfer rate. Additional overheating of the environment is also seen as a drawback.

には除去されない。To date little is known about the removal of hydrogen in conventional use. In the battery, that is, in the area used for emergency power supply, a small amount of hydrogen is continuously generated due to gas generation. For safety reasons, this hydrogen must be removed. The possibility lies in the constant aeration of equipment with suction and air supply. However, if there is a condition that hydrogen is not emitted to the outside, hydrogen is generated on the spot, that is,
Must be removed near the source. To this end, a system consisting of plates coated with a catalyst as described above is used as well. The device is flanged to the aeration conduit. The blower draws a mixture of air and hydrogen by means of the device, in which the catalytic reaction takes place on the coated surface. As in nuclear technology equipment,
Here, too, despite the forced flow-through, the conversion is small, ie the hydrogen produced is not completely removed.

The aim is to create a system which is controlled over a wide concentration range, is highly converted, and the heat of reaction generated in this case is exhausted in the existing mixture to the extent that the ignition temperature is not reached in each case.

In these studies, the premixed fuel / air mixture is guided radially by a cylindrical fibrous body, the outer surface of which is coated with a catalytic material. As fuel, a mixture of methanol and noble gas, a mixture of methanol and hydrogen or a mixture of noble gas and hydrogen is used. The efficiency of the developed burner on the effective surface is clearly higher than the overflow system. Furthermore, the measured air pollution values are essentially low.

て行われるという結論が得られる。Furthermore, theoretical and empirical operation of the system provided for improvement in nuclear energy applications shows that the reaction inside the recombiner is diffusion controlled. This indicates that the transport of the reactive material to the surface on which the catalyst acts as well as the removal of the reaction products from the surface is critical to the rate of the recombination process. In this way, it can be concluded that the installation of equipment for hydrogen reduction mainly takes into consideration the optimization of the transfer process and heat emission.

This housing has lower and upper through holes 2a or 2b so that the supply or the outflow can be prevented. In the left part of FIG. 1 there is arranged a catalyst coated plate 5a over which the mixture overflows. The hydrogen 4 is then depleted or reduced according to the efficiency of the plate. The mixture leaves the device through the upper opening 7. The right part of FIG. 1 has a horizontally arranged porous substrate, for example a mesh 5b, which is likewise coated with a catalyst, in which the hydrogen is depleted or reduced. Oxygen and hydrogen participating in the reaction are enhanced due to the side-by-side flow of the wire, resulting in a higher conversion rate. The device shown operates without external energy supply, i.e. is passive. If the device shown is flanged to the conduit system and forced through flow takes place, the through holes 2a or 2

The main member 9 with the elements 5 for catalyzing and for flowing through is sealed to said part by a seal 13. The blower for forced flow is not shown. The catalytic substrates are arranged at a slight distance from each other. Their dimensions, their mutual spacing and their number depend on the expected concentration in the mixture and the concentration permitted in the exhaust gas 7. In order to avoid ignition on the substrate--here, for hydrogen concentrations within the ignition limit and for poor heat dissipation or a small heat storage capacity--the tube member with the substrate is surrounded by a cooling jacket 3. The cooling jacket can be passed through by a fluid or gaseous medium for heat absorption. In a rational manner, the cooling medium enters the ring gap at the high mixing temperature point 10 and exits the ring gap at the low temperature point 12. In order to improve heat discharge, the flow-through section 11 may include a portion that prevents mixing. This cooling device further offers the advantage of cooling the seal which reaches its operating temperature limit due to heat conduction, convection and heat radiation. Shown is this solution and optionally a post-connected heat exchanger 8, in which part of the heat of reaction can be discharged and thus contributes to the cooling of the substrate.

反応熱の部分の吸収のために役立つ。One embodiment is represented in FIG. The cooling measures described in Figures 1 and 2 are omitted. The diameter of the tube member housing the catalytic element is chosen to be larger than the diameter of both elements 2 or 6 connected to the front or rear, since that tube member should house the spacing holder 8. Is. These serve to hold the catalytic element 5. The length of the spacing holder is flexible over the length of the device and adapted to the requirements. Its inner diameter can be chosen to correspond to the diameter of the parts 2 and 6 and consequently to be free of impacts in the flange area and thus of high pressure losses. Instead of a tubular spacing holder, other configurations are also conceivable which do not cover the entire circumference. In this case, the tube diameters of all the parts used can be chosen equally. The substrate is only partially coated to control the catalytic reaction. The uncoated region 5a serves for absorbing part of the heat of reaction.
