Description

[Detailed Description of the Invention] This invention relates to a catalytic device for an appliance that burns volatile fuel such as alcohol by bringing it into contact with a metal catalyst.

Catalytic combustion occurs simply by bringing a catalyst such as platinum or palladium into contact with a volatile fuel such as alcohol, benzene, or liquefied gas in the air, and the combustion time can be maintained for a long time, so low-temperature heating is possible. It is being used for burners, heat-retaining combustors, portable combustors, etc.

The simplest structure of this type of combustor is to attach a lid member to the main body that houses volatile fuel, and to provide a catalyst member below the heat dissipation hole bored in the lid member, so that the fuel inside the main body is catalyzed. The fuel passes through the member and flows out from the heat radiation hole, and when the fuel passes through the catalyst member, it comes into contact with the catalyst and combustion occurs.

One of the most difficult aspects of mass producing such a combustor is the structure and installation method of the catalyst component.If the catalyst component is installed incorrectly, the combustion efficiency will decrease and fuel loss will increase. combustion becomes impossible.

This idea was made in view of the above points, and it is possible to always reliably position the catalyst member under the heat radiation hole regardless of the form of the combustor or the structure of the main body and lid member. Another object of the present invention is to provide a catalytic device that can bring most of the volatilized fuel into contact with a catalytic member and combust it.

This invention for the above purpose consists of a vessel-shaped main body with an open top and containing volatile fuel, a lid member that covers the main body and has a heat radiation hole of a required size in the center, and a lid member that covers the main body and has a heat radiation hole of a required size in the center, and a This is a catalyst device for a combustor consisting of an internal catalyst device, which has the same planar shape as the heat dissipation hole but is slightly larger, has a receiving step for the catalyst member on the lower side of the interior, and has a central portion on the lower surface. a heat insulating frame member formed to protrude downward; a lattice-shaped catalyst member fitted into the frame member; and a lattice-shaped catalytic member fitted into the lower center portion of the frame member to be integrally coupled with the frame member; The combustor is comprised of a necessary shielding plate that partitions the inside of the combustor into upper and lower sections and closes the combustor airtightly.

Ceramic or the like is used as the frame member, and a metal catalyst such as platinum or palladium is used as the catalyst member.

This invention will be explained in detail below using illustrated examples.

1 is a container-shaped body with an open top, air holes 2,
It has 2. Reference numeral 3 denotes a lid member that fits into the opening edge of the main body 1, and has a rectangular heat dissipation hole 4 bored in the center, and grooves 5, 5 communicating with the air holes 2, 2 on the opening line. It is provided. Furthermore, support pins 7, 7 for the catalyst device 6 are provided protruding from the inside of the lid member 3.

The catalyst device 6 is composed of a frame member 8 made of ceramic, a lattice-shaped catalyst member 9 fitted into the frame member 8, and a shielding plate 10.

The frame member 8 is formed in a rectangular shape that is slightly larger than the heat radiation hole 4, and has a stepped portion 8a for receiving the catalyst member 9 on the inside lower side. The center portion of the lower surface is formed to protrude downward, and the shielding plate 10 is fitted around the protrusion 8b. Across the upper surface of the shielding plate 10 and the frame member 8, there are a plurality of retaining pieces 11, 11, which have one end locked to the shielding plate side and the other end bent. The plate 10 is attached to these stoppers 11, 11.
are integrally connected by.

The shielding plate 10 is formed in a size that contacts a step formed inside the opening edge of the lid member 3, and has a mounting hole at the position of the support pins 7, 7, and is inserted into the mounting hole. It is fixed to the lid member side by caulking the tip of the support pin, dividing the inside of the container into upper and lower parts and closing the container airtightly.

In the combustor equipped with the catalyst device 6, all the volatile components of the gelled fuel 12 put into the main body 1 are
The shielding plate 10 allows the air to pass through the catalyst member 9. In addition, the air necessary for combustion is taken in from the air holes 2, 2 on the side of the main body, and the volatilized fuel mixes with the air and causes a reaction when it comes into contact with the catalyst member 9, causing combustion and releasing heat. The object inside the hole 4 or above the heat radiation hole 4 is heated.

As described above, this invention is based on the structure of a catalytic combustor using a heat insulating frame member 8, a lattice-shaped catalyst member 9 fitted into the frame member 8, and a shielding plate 10 attached to the frame member 8. 1, the catalyst member can be easily attached, and the catalyst member can be positioned directly below the heat radiation hole. Furthermore, the area around the frame member can be closed off by the shielding plate, and most of the volatilized fuel can be brought into contact with the catalyst member within the frame member, resulting in less combustion loss and higher combustion efficiency.
Furthermore, not only can the frame member be used as a pedestal for a heated object placed in the heat radiation hole, but the shielding plate can also be used as a mounting member for the frame member.
