The distribution frame 3 is formed of a circular frame body 31 having a diameter and a height corresponding to the distribution plate 13 and the distribution rotor 2 of the rotor housing 1, clogged on the side surface, and opened to the lower side. It is connected to the distribution plate 13 of the housing 1 and is formed by forming a number of vertical distribution holes 32 of the frame on the upper surface.

In the present invention configured as described above, as shown in FIG. 16, untreated gas is first sucked through the intake port 11 formed in the lateral direction of the rotor housing 1, and the sucked untreated gas is It moves to the vertically upward distribution plate 13 side. Then, after passing through the inner distribution hole 14 of the distribution plate 13 and the outer distribution hole 15 of the distribution plate, the untreated gas that has moved to the outer distribution hole 15 side of the distribution plate is again supplied to the vertical distribution rotor 2. By being supplied to the distribution chamber 133 side of each of the duct 132 and the distribution layer 130 through the air holes 26 , heat exchange is performed through the heat storage chamber 122 of each of the heat storage layers 12, and then sent to the combustion chamber 110 for combustion. (See Figure 5.)

The processing gas thus burned again exchanges heat while passing through the heat storage chamber 122 of each heat storage layer 120, and the heat exchanged processing gas is distributed to the distribution frame 3 through the distribution chamber 133 of each distribution layer 130. After being discharged to the rotor housing 1 through the vertical exhaust hole 26 formed so as to penetrate vertically through the rotor 2 surface, it is repeatedly discharged again in the lateral direction of the exhaust port 12 of the rotor housing 1. It is.

As described above, the present invention makes it possible to easily attach and detach the distribution device including the distribution rotor to the bottom surface of the central portion of the equipment body including the distribution layer, the heat storage layer, and the combustion chamber. By configuring the distribution frame fixed to the main body so that it can be easily separated and assembled, it is possible not only to replace and maintain the distribution rotor more easily, but also to improve the efficiency of the work associated with shortening the time. This can be further improved, and the economics of cost reduction can be further increased by simplifying the structure of the distribution rotor, and the gas supplied to and exhausted from the inside of the equipment body through the rotor housing is not broken in the middle, and the vertical direction The unprocessed gas through the rotor housing is separated from the distribution layer and And, when the treated gas supplied to the combustion chamber is exhausted again through the rotor housing, the pressure loss generated by the gas being supplied and exhausted from the middle to the side direction and then again in the vertical direction can be minimized. In addition to this, it is possible to further improve the performance and reliability of the device.

As described above, the present invention makes it possible to perform painting and drying, which are separate conventional facilities, together in one facility, and increases price competitiveness without the need for an expensive catalyst device. It becomes possible to further increase the economic efficiency. In addition, the harmful substances generated at the time of painting are not removed by filtration and filter devices using activated carbon or catalysts, but are not burned by using a heat storage combustion facility equipped with a distribution chamber, a heat storage chamber, and a combustion chamber. It can fundamentally solve the loss of filter function caused by the phenomenon that the paint dust sticks to the filter and can minimize the concentration of harmful substances in the exhaust gas, and can cope with the compliance by gradually becoming more severe environmental regulations It will be like that.
