Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing apparatus for deodorizing odorous gas in equipment that generates odorous gas, such as a kitchen garbage disposer for processing garbage and the like.

[0002]

2. Description of the Related Art In a conventional catalytic deodorizing apparatus, as a deodorizing operation process, an odorous gas is heated in advance to a catalytic reaction temperature at which the effect of the catalyst can be sufficiently exerted. The catalyst is deodorized by injecting a gas into a cross section of a heating catalyst element in which an oxidation catalyst is supported on a substrate such as alumina or cordierite having a cross section formed in a lattice shape or a honeycomb shape and passing the inside thereof. Such is generally known.

Further, a ceramic heater is provided inside a cylindrical outer case provided with an intake port and an exhaust port, and a continuous band-shaped metal fin is spirally wound therearound. By heating the ceramic heater while supporting the catalyst, the odor gas sucked from the intake port is
Japanese Patent Application Laid-Open No. Hei 8-1552 discloses a method in which the air is purified by passing through a path formed by an inner wall of an outer case and metal fins, and the purified air is discharged from an exhaust port.
No. 66 is published.

[0004]

Under such circumstances, in order to enhance the deodorizing effect, the contact time between the odor gas and the deodorizing catalyst must be made as long as possible. The design that it aims at shaping is adopted. However, the fact that the size of the deodorizing catalyst increases means that the cooling of the deodorizing catalyst is promoted, and therefore, it is not possible to maintain the catalytic reaction temperature necessary for sufficiently obtaining the effect of the deodorizing catalyst, Despite the large cost and the large size of the deodorizing catalyst, there was a problem that sufficient deodorizing results could not be obtained.

In the deodorizing device disclosed in Japanese Patent Application Laid-Open No. 8-155266, a small and simple deodorizing device can be provided without incurring a large amount of cost, but it is absorbed into the device. Since the temperature of the odorous gas increases from the intake port to the exhaust port, the effect of the catalyst carried on the surface of the metal fin is exerted as the exhaust port is approached. Could not get.

A first band-shaped fin made of metal spirally wound along the outer periphery of the heater, and a specific distance along the heater from the first band-shaped fin. A metal second band-shaped fin, a first deodorizing catalyst provided between the first band-shaped fin and the second band-shaped fin, and a gas supply port provided on an exhaust port side in the outer case. A deodorizing device was constituted by the second deodorizing catalyst.

DESCRIPTION OF THE PREFERRED EMBODIMENTS According to the present invention, the odor gas sucked from the inlet of the outer case is formed by the inner wall of the outer case and the first band-like fin. The heat is sufficiently heated by the ceramic heater as it passes through the passage, and the first purification is performed by passing through the first deodorizing catalyst. The gas being cooled by passing through the inside of the first deodorizing catalyst is heated again as it passes through the path formed by the inner wall of the outer case and the second strip fins. Then, a second purification is performed by passing through the second deodorizing catalyst, and is discharged from the exhaust port.

FIG. 3 is a side view showing a state in which the fins 6 are wound around the cartridge heater 4, and FIG. 3 is an external view showing a first deodorizing catalyst of the deodorizing apparatus in one embodiment of the present invention.
FIG. 4 is an external view showing the second deodorizing catalyst.

Reference numeral 1 denotes an outer casing made of metal having a substantially cylindrical shape and a hollow inside, 2 is an intake port provided at an upper portion of one end of the outer casing 1, and 3 is an outer casing. An exhaust port provided at the center of the other end of the switch 1. Reference numeral 4 denotes a rod-shaped ceramic heater provided inside the outer casing 1, and reference numeral 5 denotes a first band-shaped metal fin spirally wound along the outer periphery of the ceramic heater 4. , 6 are metal second band fins provided at a specific distance from the first band fin 5 along the ceramic heater-4. Reference numeral 7 denotes a first deodorizing catalyst provided between the first band-like fin 5 and the second band-like fin 6, and 8 denotes an outer casing.
This is a second deodorizing catalyst provided on the side of the exhaust port 3 inside the exhaust gas 1.

Here, the specific distance between the first band-like fin 5 and the second band-like fin 6 is set to a size sufficient to accommodate the first catalyst 7.

Next, a description will be given of the deodorizing action of the embodiment constructed as described above.

In FIG. 1, odor gas generated from a kitchen garbage disposer (not shown) such as garbage is sucked in from an intake port 2 and formed by an inner wall of an outer case 1 and a first band-like fin 5. As the vehicle enters the route, it is heated to a temperature higher than the catalytic reaction temperature at which the catalytic effect can be sufficiently exerted as it passes through the route, and passes through the first catalyst 7 for the first time. The odorous gas whose temperature has been reduced by the purification process enters the path formed by the inner wall of the outer case 1 and the second band-like fins 6, and passes through the path. The second catalyst 8 is heated again by passing through the second catalyst 8, and is then discharged to the outside through the exhaust port 3 after being sufficiently deodorized.

According to the present invention, a first deodorizing catalyst is provided between a first band-like fin and a second band-like fin in an outer case of a catalytic deodorizing apparatus, and a second deodorizing catalyst is provided near an exhaust port. By providing a deodorizing catalyst, odor gas can be reduced
And the first strip fins are sufficiently heated to the catalytic reaction temperature, subjected to the first purification by the first deodorizing catalyst, and further heated sufficiently by the second strip fins to the second strip fin. Since the second purification is performed with the deodorizing catalyst, a sufficient deodorizing effect is obtained and released from the exhaust port.
A small and high-performance deodorizing device can be provided without incurring a large cost. In other words, the odor gas sucked in from the intake port is heated and deodorized stepwise by two types of processes and then reaches the exhaust port, so that the gas released from the exhaust port has little odor, and therefore, Outer case
There is always clean air around the area.
