Description

[Detailed description of the invention] The present invention relates to a combustion equipment m used for burning gas containing flammable gas, such as exhaust from a paint booth or deodorizing equipment, to make it non-tatami. The present invention relates to a combustion apparatus provided with a heat exchanger for mutually exchanging heat between a gas to be treated containing combustion substances in a combustion base and an exhaust gas from a combustion storm.

In the Hinoki m-device, the heat exchange medium in the heat exchange chamber is rotated, and the medium is applied to the constant Q combustion gas flow path and the exhaust gas (from the combustion section) flow path. Mechanisms are known that include means for positioning the heat exchange footwear and means for directing the heat exchange footwear.

However, in the rotary model of 10 people, heat exchange wI &
9th, the body is constantly exposed to high temperatures of 700 to 800°C, and the seals at the mold contact points between each flow path and the medium are difficult to seal, and the sealing performance is fast. Medium! II
Due to the drawback that too much driving power is required to rotate #-i, it can be used with a K lid or with a small number of IlllII lids, but it cannot be used in the above-mentioned use due to the above-mentioned drawback.

Also, the second route switching certificate is shown in Figure tg A).

(b) As shown, the heat exchange tank (07) is connected to the combustion chamber (
01) IIli1MK multiple protrusions are arranged,
At the outer end of this heat exchanger 411 (Of), each duct) (04
The upper and lower ends of this duct (040) are connected to the annular combustion gas supply duct (04g) and the exhaust gas outlet duct (0413) through the damper (041).
It is known that the W structure has a structure that is connected to the W structure, but the W structure has the following drawbacks.

■ 11a Yakinen (01) w4 The heat exchanger @ (07) where gas flows in the horizontal force direction outwards and the dak l- (041) are protruded and the 9th one has a unique structure. The pile-up will inevitably be significantly larger than that of the M1II.

■ Since the gas flow in the heat exchanger 11 (07) is directed in the horizontal direction, the volume of Ifi cedar wood for heat exchange stored in this exchanger 11 (07) will decrease. Upper KwA
9 darkness occurs without cedar wood, and cold cedar combustion gas with no heat exchange is supplied to the combustion storm, or il! The drawback is that hot gas is released to the outside world.

In addition, in order to eliminate such drawbacks, it takes a lot of time and effort to work in the snow.
I hate the drawbacks of doing so.

■ Since the damper (041) is heated and cooled by selective contact with the combusted gas before heat exchange and the exhaust gas after heat exchange, the damper (041) is heated and cooled repeatedly during use.
There is a disadvantage that the moving parts are free of f'), and this disadvantage can easily cause an accident in which unburnt combustible gas is dissipated to the outside of the casing.

Furthermore, there is also a drawback that the sealing performance of the damper becomes cloudy compared to the 1g$1 j&L rc, which causes unburned gas to dissipate.

■ Since a unique damper is required for each of the multiple island exchange rights, the opening/closing control of the multiple dampers becomes delicate, which has the drawback of making it easy for operational errors to occur. , ■ has the disadvantage that the accidents shown in (■) are more likely to occur.

The most sincere and serious invention is the one mentioned above.

■Practicality in eliminating deficiency 14 and flow path switching salt 1
Also, Fudo 8 Takaaki uses the configuration of the first invention to achieve the same as above.
The purpose is to eliminate the drawbacks of No. 41L and improve not only the coldness but also the paranoia in the flow path switching 11i.

First, 1ffk! , in the combustion device for red bean paste, 1
In order to change the purpose of the new era! IQk! , In the heat exchanger tank, there are four inertia and *a storage tanks arranged in parallel, and these storage tanks and solid materials for heat exchange are filled in the Ryukicho-machi. At the same time, the combustion chamber is connected to one end of the plurality of reservoirs, and the combustion chamber is connected to the other end, and the processing gas is supplied to 41. A port and an exhaust gas outlet are provided, and the supply port and #distribution port are connected to -〇 storage w storm! A valve for selectively switching between the 1141 and 1141 units is provided at the IQ register and FF, and the configuration is adopted.

With this configuration, the flow of gas in the heat exchange tank is the same as above, and therefore, even if the volume of the heat exchanger filled in the storage tank is slightly 9, the gas flow is the same. As a result, the cold combusted gas may expand into the combustion chamber, or the high-temperature exhaust gas may leak into the outside world. Furthermore, by making the gas flow t in the upward direction in this way, the overall direction of the device can be made to have a size K that is equal to or not much different from the gas a-. Kade dust,
In the fuel device of the second invention, the storage capacity is J6.
As the above-mentioned I11 Hatsucho 0 valve structure, in IIa Book Constitution,
-Axis-Rini l! ! A wall-shaped valve body is provided so as to be freely rotatable, and the valve body is divided into two parts by this depressed valve body. The valve body is arranged in parallel with the rotating valve body, and the supply port is opened to the force on one side of the front wall-folding valve body, and the exhaust gas outlet is opened to the force on the other side of the wall-folding valve body. The structure is adopted to achieve the above purpose.

By adopting this Ilbo, not only does it have the above-mentioned 1st Yoshikawa's work F @ Yorai, but also it has 1 heat exchanger at either the upper or lower end of the heat exchange, depending on the configuration of the 1011 town. By making use of the fact that it becomes easier to obtain R passage 64 by bringing the previous combustion gas close to the exhaust gas after heat exchange, it has been possible to eliminate the deficiencies in (1) and (2) by at-4%.

Since the collection valve body is simultaneously in contact with the combusted gas before heat exchange and the exhaust gas after heat exchange, this valve body is subject to large temperature changes during use. Therefore, malfunctions such as the one mentioned above due to thermal fluctuations are less likely to occur, and the rotation operation can be performed extremely smoothly. Also, the communication relationship between the supply ports and outlets for multiple storage chambers has been improved. Switching is done by rotating this valve body, so there is no need for complex operations such as switching multiple dampers, and there is no risk of operational errors, and the simple rotating structure minimizes the risk of failure. There are few.
