Embodiment Construction

[0052] Hereinafter, a catalytic type regenerative combustion device 1 according to a preferred embodiment of the present invention will be described with reference to the drawings.

[0053] The catalytic thermal storage combustion device 1 is a so-called catalytic thermal storage combustion device for purifying the exhaust gas by burning combustible harmful components in the exhaust gas. In this specification, exhaust gas refers to gas containing combustible and harmful components such as harmful components and volatile organic compounds discharged from various production facilities and processing facilities. In addition, the flammable harmful components contained in the exhaust gas are flammable harmful components such as toluene and ethyl acetate, volatile organic compounds, and the like.

[0054] figure 1 It is a schematic perspective view of the catalytic type regenerative combustion apparatus 1 which concerns on the preferable embodiment of this invention. figure 2 It...

Abstract

An object of the present invention is to provide a catalytic type regenerative combustion device that does not overheat a catalyst, is easy to perform maintenance operations, and can be operated at low operating costs. The catalytic heat storage combustion device (1) of the present invention is used to burn combustible and harmful components in the exhaust gas to purify the waste gas. The body (11, 21) and the catalyst (12, 22) are arranged in sequence in each heat storage purification chamber (10, 20), and the exhaust gas can pass through the heat storage body (11, 21), and the catalyst (12, 22) Used to burn combustible and harmful components; a heating chamber (30), which has a heating portion (31') for heating exhaust gas, and the heating chamber (30) is equipped with a catalyst in each heat storage purification chamber The sides are respectively connected with each heat storage purification chamber in a plurality of heat storage purification chambers; The flow of the exhaust gas is switched so that the exhaust gas is supplied to one of the thermal storage purification chambers, and the heating unit is arranged at a position where radiation from the heating unit does not reach the catalyst.

Description

technical field [0001] Generally speaking, the present invention relates to a catalytic type regenerative combustion device, and in detail, relates to a method of using catalytic combustion treatment to detoxify combustible harmful components contained in exhaust gas and to recover the heat of the treated exhaust gas for use in Catalytic regenerative combustion unit for preheating of untreated exhaust gases. Background technique [0002] From the point of view of pollution prevention, waste gas containing harmful components or combustible harmful components such as volatile organic compounds discharged from various production equipment and processing equipment cannot be directly discharged into the atmosphere. Therefore, such exhaust gas is released into the atmosphere after being detoxified by an exhaust gas treatment device. [0003] As such an exhaust gas treatment device, a thermal storage combustion device has been proposed, in which a thermal storage chamber containin...
