〈産業上の利用分野〉
本発明は触媒燃焼式熱風発生法に関する。さらに詳しく

焼器に関するものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a catalytic combustion hot air generation method. More specifically, the present invention relates to a catalytic combustor that is visually suitable for extracting the heat obtained by burning a lower hydrocarbon fuel such as butane on a catalyst as hot air.

生機器に応用されている。<Prior art> Attempts to utilize the heat obtained by burning fuel on a catalyst have been known for a long time, and have been known for a long time, such as self-sustaining combustion, the ability to freely and uniformly obtain the required temperature, and flameless combustion. Taking advantage of its high safety characteristics, it has been applied to portable consumer devices such as hand warmers, small heaters, and small hair beauty devices such as hair curlers.
しかもこの場合、可搬型民生機器としての構造と着火性
から触媒の熱容量が小さく、かつ構造を任意に変えられ

。Moreover, in this case, a fibrous mat is widely used as an advantageous catalyst because of its structure as a portable consumer device and its ignitability, which has a small heat capacity and whose structure can be changed arbitrarily.

未燃焼炭化水素（ＵＨＣ）および−酸化炭素（ＣＯ）の
排出が急増してしまうという欠点を有している。However, in order to simplify the equipment and take into consideration risks such as backfire, the above technology does not pre-mix the fuel and molecular oxygen-containing gas as an oxidizer, so that the fuel diffused from inside the catalyst layer is Diffusion combustion is mainly used, in which catalytic combustion occurs in contact with air that diffuses from the surface into the interior of the catalyst layer due to natural diffusion. The calorific value per unit surface tends to be kept low at 1.51<cal/cIi1hr, but if more fuel is supplied, unburned hydrocarbons (UHC) and carbon oxides (CO) will be emitted. It has the disadvantage of increasing rapidly.

汚染するというゆゆしい問題が生じざるをえなかった。Therefore, it is difficult to apply these conventional technologies to equipment that requires a large amount of heat, as the amount of catalyst increases, which in turn increases the size of the equipment. In the case of hair dryers, etc., which use the generated heat as hot air, the fibrous catalyst becomes powdered and scattered, causing serious problems such as polluting the environment.

The purpose is to enable application to small power generators, etc. in combination with warm air heaters, flameless torches, or thermoelectric conversion elements.

。<Means of the Invention> In the present invention, a raw material gas prepared by premixing a lower hydrocarbon fuel and a molecular oxygen-containing gas so as to have a composition within the flammable range is supplied to a monolith type catalyst, and then further mixed so as to have a composition within the flammable range. Combustion obtained by catalytic combustion by diluting with a molecular oxygen-containing gas and supplying it to the catalyst to cause catalytic combustion, while supplying an inert gas or molecular oxygen-containing gas for cooling and dilution to the side of the catalyst body. It is characterized by being mixed with gas.

大きいセラミック製のモノリス触媒でも容易に着火せし
めるようにし触媒燃焼が自立するのに十分な触媒層燃焼
活性温度とせしめるものである。In other words, the present invention differs from the surface diffusion method in that the entire amount of fuel and the amount of molecular oxygen-containing gas, such as air, required for its complete combustion are premixed initially so that the composition is within the combustible range. The space velocity through the catalyst layer is controlled to be low, and even ceramic monolithic catalysts, which have a larger heat capacity than fibrous matte catalysts, can be easily ignited. It is something that urges us to do so.
このように着火せしめたのち、燃焼範囲下限値未満の組

有ガスや炭酸ガス、窒素などの不活性ガスで希釈して供
給して触媒燃焼せしめ、さらに触媒体側面へはモノリス
触媒層からの高温燃焼ガスを冷却希釈するだめの空気等
の分子状酸素含有ガスや不活性ガスを導入する。After igniting in this way, the raw material gas is further diluted with a molecular oxygen-containing gas such as air, or an inert gas such as carbon dioxide or nitrogen, so that the composition is below the lower limit of the flammability range, and then supplied for catalytic combustion. Furthermore, a molecular oxygen-containing gas such as air or an inert gas is introduced into the side surface of the catalyst body to cool and dilute the high-temperature combustion gas from the monolithic catalyst layer.

きる。Therefore, the combustion gas generated by catalytic combustion can be immediately cooled and diluted to produce hot air at the desired temperature and amount, making it possible to obtain a large amount of hot air with a small capacity catalyst. The calorific value per unit surface area of the catalyst is 10
~5Qkcal/cr!・It is possible to reach even hr.

用等のな
送風用モーターも小さ■出力のもので使用可能という特
徴を有する。In addition, by using a monolithic catalyst, there is no possibility of the catalyst itself being powdered and scattered, as is the case with fibrous matte catalysts, and the hot air is clean and does not substantially contain unburned UHC, Co, and nitrogen oxides (NOx). It has the characteristics that not only hot air can be obtained, but also the pressure loss due to the catalyst is smaller than that of a fibrous matte catalyst, and the blower motor for cooling and dilution can also be used with a small output.
予備混合および触媒燃焼に用いられる分子状酸素含有ガ
ス、好適には空気の量は触媒量、燃料量およびその発熱
量、目的とする熱風の温度および量等によって最適量が
決定される。The optimal amount of the molecular oxygen-containing gas, preferably air, used for premixing and catalytic combustion is determined by the amount of catalyst, the amount of fuel and its calorific value, the temperature and amount of the intended hot air, and the like.
特に予備混合に用いられる分子状酸素含有ガス量は、瞬

好ましくは３０〜５０チの範囲で混合することが適して
おり、かつ安定な触媒燃焼を遂行するために燃焼範囲外
の希薄混合ガス組成とせしめたときの燃焼ガス到達温度
は４００℃から１２００℃の範囲となるように調節せし
められる量が好ましい。４００℃に達しない場合は′
温度が低くかつ風量が多くなるため触媒燃焼が自立し難
くなり、一方１２００℃を超えると、燃焼範囲に近づく
結果、火炎が発生し易くなり、又、触媒の耐久性も短く
なる。In particular, the amount of molecular oxygen-containing gas used for premixing may be an amount that instantly ignites and raises the temperature to the catalyst activation temperature, but then further molecular oxygen-containing gas is supplied to quickly increase the combustion range. In order to achieve a stable and safe catalytic combustion with a gas composition below the lower limit, 20 to 60% of the total amount of molecular oxygen-containing gas passing through the catalyst layer,
Preferably, it is suitable to mix in the range of 30 to 50 inches, and in order to achieve stable catalytic combustion, the temperature reached by the combustion gas is from 400°C to 1200°C when a lean mixed gas composition is made outside the combustion range. It is preferable to adjust the amount so that it falls within the range of . If the temperature does not reach 400℃,
Since the temperature is low and the amount of air is large, it becomes difficult for catalytic combustion to become self-sustaining. On the other hand, when the temperature exceeds 1200°C, flames are more likely to occur as a result of approaching the combustible range, and the durability of the catalyst is also shortened.
触媒担体は、燃料と分子状酸素含有ガスとの拡散を容易
にかつ均一にさせ、又着火時以外は触媒燃焼を自立させ
る目的から空隙率、開孔度が大きく、かつ比重、比熱の
小さいものが適しており燃料の吹き抜けを防止するため
、一体物の積層体もしくは成型体が適している。The catalyst carrier must have a large porosity and porosity, and a small specific gravity and specific heat in order to facilitate and uniform diffusion of the fuel and molecular oxygen-containing gas, and to enable independent catalytic combustion except during ignition. A one-piece laminate or molded body is suitable to prevent fuel from blowing through.

ミックよりなるハニカム構造体が最も適している。As a carrier that satisfies these requirements, inorganic fiber laminates or molded bodies such as alumina, silica, and alumina-silica having a packing specific gravity (I/CC) of 0.02 to 0.8 are most preferable. Because of the problem of powdering and scattering, a honeycomb structure made of ceramics such as cordierite or mullite having similar specific gravity is most suitable.

。The catalytic active component is optimally selected depending on the type of fuel, but platinum group elements such as platinum, palladium, and rhodium are usually suitable, and these can be supported on the above carrier alone or in combination of two or more, and The above-mentioned carrier is coated in advance with activated alumina in the crystal form of γ, η, θ, etc. having a surface area of 50 to 200 z/I, and platinum group elements are supported on the coating layer to form the finished catalyst. Suitable component loading (2) is 0.01 to 10% by weight, preferably 0.1 to 2% by weight, based on the finished catalyst, and the coating amount of activated alumina is 95 to 40% by weight, preferably 10 to 30% by weight, based on the finished catalyst.

ながり、熱風発生器設計上好ましくない場合が多い。The size of the catalyst needs to be a certain size in order to reduce the passing space velocity of the fuel-molecular oxygen-containing gas mixture and ensure stable combustion, and the larger the catalyst unit surface area, the better. However, on the other hand, an increase in catalyst capacity, catalyst diameter, and catalyst layer length leads to an increase in ventilation resistance and an increase in the size of the entire combustor, which is often unfavorable in terms of hot air generator design.
