When the exhaust gas is introduced into the catalyst purifying device main body, the exhaust gas first deprives the heat storage body by passing through the heat storage body having a honeycomb structure. Further, in the heating device, the catalyst is heated until it reaches a temperature at which the catalyst needs to be purified, passes through the catalyst, and the harmful substances are oxidized and purified. When passing through the other heat storage element, the heat energy of the exhaust gas is taken away by the heat storage element, cooled and released. After a certain time, the flow direction of the gas in the catalyst purification device main body is reversed. That is, the heat storage body, which was initially located on the gas outlet side, is in a state where heat energy has been sufficiently removed from the gas purified by the catalyst. Heat is supplied to the exhaust gas introduced into the main body of the catalyst purification device, which serves as a heat storage body. Conversely, the heat storage body that was initially on the inlet side has been deprived of heat by the exhaust gas. By reversing the flow direction of the gas, the heat storage body is changed to a side that deprives the exhaust gas purified by the catalyst of heat energy. This means that part or most of the thermal energy required to heat the exhaust gas to the temperature required for purification is confined inside the catalyst purification device body, which means that the heat loss discharged can be reduced. I do. The structure and amount of the heat storage is directly related to the heat exchange efficiency. A heat storage element having a honeycomb structure made of ceramic can be used as a heat storage element having the best air flow structure, heat capacity, and corrosion resistance. The amount of the heat storage body having the honeycomb structure with respect to the flow rate of the processing gas needs to have a surface area ratio of 60 to 1200 cm / h. This condition shows the relationship between the total amount of the heat storage bodies in two layers and the air volume. When a honeycomb structure made of ceramic is used as the catalyst, the amount of the catalyst is added to the amount of the heat storage body and used. The switching time of the gas flow direction is set so that the heat capacity of one of the heat accumulators is three times or more the amount of heat for raising the exhaust gas to a required temperature.
By the action of the heat storage body having the honeycomb structure, it is possible to provide a catalyst purifying apparatus having a small heat loss and a high resistance to corrosion.

ものである。As is apparent from the above description of the embodiment, according to the catalyst purifying apparatus of the present invention, both ends of the catalyst purifying apparatus main body have gas inlets and outlets for alternately converting gas inlets and outlets. A heating device and a catalyst are installed at the center, and the structure has a honeycomb structure heat storage element in the middle of the gas flow path from both ends to the center, and exhaust gas containing harmful components is introduced into the catalyst purification device from one end for a certain period of time. After being heated by the heat storage element and the heating device and then purified by the catalyst, the heat is cooled by the other heat storage element and discharged from the other end. Next, the direction of the gas flow is reversed by switching the damper, and the exhaust gas is introduced into the main body of the catalyst purification device for a certain period of time and discharged through the same heating, purification and cooling processes. The relationship between the air volume at this time and the surface area of the heat storage body having a honeycomb structure is set in the range of 60 to 1200 cm / h, and this operation is repeated alternately to minimize the loss of heat energy and to reduce harmful components in the exhaust gas. It is intended to realize a catalyst purification device that can efficiently combust and purify the catalyst.
