JPS6179909A - Catalyst case for purifying ignited and discharged gas - Google Patents

Abstract

PURPOSE:To provide a catalyst case which can be adapted for any type of combustion units by a method wherein fitting part for the ignition unit is arranged at one belt-like piece of the fitting hardwares and longitudinal holes to be engaged with -shaped projections of a main body of the catalyst case are made in the other belt-like piece. CONSTITUTION:In order to assemble a fitting hardware 1 with a main body 2 of a case, at first a catalyst 11 is fixed to the main body 2 of the catalyst case. At this time, it is the simplest process to place and fix the catalyst on the projections 4 of the catalyst case. Then, the fitting hardwares 1 are fixed. The fitting hardwares 1 are inserted in such a way as they are in parallel with T-shaped projections 3 of the main body 2 of the catalyst case and then they are rotated by a degree of 90 deg.. With this arrangement, the pieces 6 having longitudinal holes 9 of the fitting hardwares are fitted inconcave parts 5 of the T-shaped projections 3 and can be moved in a direction of arrow X, however, they may not be out of the main body. With this arrangement, the position of the fitting holes 10 for the top plate can be varied freely, resulting in that the catalyst case can be fixed to any types of petroleum stoves.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention aims to purify the combustion exhaust gas of gas, oil, etc., more specifically, to purify the exhaust gas of combustion equipment for gas, oil, etc., which has a combustion tube and a top plate. Regarding the catalyst case.

Conventional technology Among gas, oil, and other combustion appliances, those that emit combustion exhaust gas indoors, such as reflector type combustion heating appliances, do not oxidize harmful gases such as carbon monoxide and hydrocarbons in the exhaust gas. For purification, oxidation catalysts have become widely used. Various installation methods and locations for this oxidation catalyst have been proposed, but all of them are installed in a cylindrical case to allow for the natural flow of combustion exhaust gas and to efficiently introduce exhaust gas into the catalyst. The catalyst is housed and installed with a designated space between the combustion tube and the top plate.

The catalyst case consists of a cylindrical body that houses the catalyst, and a mounting part that protrudes from the main body and is fixed to the top plate of the combustion equipment. is alms.

Problems to be Solved by the Invention Since the catalyst case designed in this manner is compatible with kerosene stoves, it can only be installed in designated kerosene stoves. For this reason, very few oil stoves, gas stoves, etc. currently in use can be equipped with catalysts.

An object of the present invention is to provide a catalyst case that can be adapted to any type of reflective type stoves, such as kerosene stoves and gas stoves, which are already widely used today.

Means for Solving the Problems The catalyst case of the present invention includes a cylindrical case body having a pair of T-shaped protrusions at one end for fixing the catalyst, and two T-shaped protrusions parallel to each other.
It consists of a pair of metal fittings each having two band-like parts, one of the metal fittings has a mounting part for the combustion equipment, and the other band-like part has an elongated part that engages with the T-shaped protrusion on the case body. It was established.

If the protrusion of the case body is inserted parallel to the long length of the working metal fitting and the metal fitting is moved perpendicularly to the protrusion, the protrusion engages with the metal fitting, and the case body can be suspended by the metal fitting. Then, attach the mounting part of the metal fitting to the top plate of the combustion equipment.

Embodiment Fig. 1 is a plan view of a catalyst case according to the present invention, Fig. 2 is a front view thereof, Fig. 3 is a front view of the case body, Fig. 4 is a plan view of the metal fittings, and Fig. 6 is a front view thereof. be.

This catalyst case consists of a pair of metal fittings 1, 1 and a case body 2.
It consists of The catalyst case body 2 has a cylindrical shape with a pair of T-shaped protrusions 3.3 at opposing positions on the upper end and a plurality of protrusions 4 for fixing the catalyst. The T-shaped protrusion 3 has a recess 6, which allows connection with a metal fitting.

The metal fitting 1 connected to this protrusion has a structure in which two parallel strip pieces 6 and 7 are connected by a connecting piece 8. An elongated hole 9 is provided so that it can be connected to the shaped protrusion, and a tapped hole 10, which is necessary when connecting to the kerosene stove body, is provided in the other strip piece. In addition, when the connecting piece 8 sets the catalyst and attaches it to the kerosene stove, the combustion gas from the kerosene stove passes through the catalyst and between the catalyst and the top plate, so that it provides a necessary gap and reverses the flow. This is for positioning to prevent the catalyst from being installed too close to the combustion tube, and its length, that is, the distance between the strips 6.7, is determined in the range of 10 to 50 mm.

To assemble the metal fitting 1 with the case body 2, first, the catalyst 11 is fixed to the catalyst case body 2, as shown in FIG. At this time, the easiest way to fix the catalyst is to place it on the protrusion 4 of the catalyst case. Next, the metal fitting 1 is fixed to this. As shown by the dotted line in the upper part of FIG. 1, the metal fitting 1 is inserted so that its elongated hole 9 is parallel to the T-shaped protrusion 3 of the catalyst case body 20, and then rotated 90 degrees.

By doing this, the piece 6 with the elongated hole 9 of the metal fitting is
The T-shaped protrusion 3 is fitted into the recess 5 and is movable in the direction of the arrow X in FIG. 1, but does not come off the main body. Being able to move in the direction of arrow X means that the position of the mounting hole 10 with respect to the top plate can be changed freely, making it possible to mount it on any type of kerosene stove. 6th
The figure shows the state in which it is actually attached above the combustion tube 13 of the kerosene stove 12. The top plate of a kerosene stove has a hole drilled in it to allow exhaust gas to escape, but the location of this hole varies depending on the manufacturer and model. Therefore, as shown in the figure, it is necessary to attach it at point A or point B, but in the catalyst case of the present invention, the metal fitting 1
can be moved freely.

Effects of the invention (1) Since the catalyst mounting hole can be moved freely according to the mounting position of the top plate, it can be installed in any model of kerosene stove made by any manufacturer.

(2) Since the metal fittings can be easily attached to the catalyst case body, they can be moved while being removed. Its small bulk is advantageous for transportation, etc.

(3) The metal fittings also have the effect of preventing the catalyst from falling out.
