[0031] Such as figure 1 As shown, the present embodiment provides a catalytic converter 100a, which includes a catalytic converter housing 110, a catalytic converter inner tube 120 fitted with a small gap between the catalytic converter housing 110 and a plurality of catalytic elements for catalyzing exhaust gas 130.

[0032] The small gap between the catalytic converter housing 110 and the catalytic converter inner tube 120 not only ensures that the catalytic converter inner tube 120 can move relative to the catalytic converter housing 110 , that is, it can leave or enter the catalytic converter housing 110 . This ensures that the catalytic converter housing 110 and the catalytic converter 100a can be closely fitted together, and the relative position of the two will not change without the action of external force. The small-gap fit mode used in this embodiment means that there is a gap between the catalytic converter housing 110 and the catalytic converter inner tube 120, b...

[0047] The structure of the catalytic converter 100b provided in this embodiment is basically the same as that of the catalytic converter 100a provided in Embodiment 1, the difference is that the catalytic converter 100b provided in this embodiment is additionally equipped with a second filter plate 153, and the catalytic element The 130 has a slightly different construction.

[0048] see figure 2 , the second filter 153 is arranged on the gas outlet side of each catalytic element 130, and is used to intercept the catalyst particles blown off by the gas flow. Preferably, in order to further enhance the catalytic effect, a catalyst may also be attached to the gas outlet side of the second filter 153 close to the catalytic element 130 , and a layer of gauze is provided on the opposite side to trap catalyst particles.

[0049] It should be noted that the second filter sheet 153 may be only a layer of tulle for trapping catalyst particles. At the same time, in the case of ensur...

Abstract

The invention relates to the field of environment, in particular to a catalytic converter and a catalytic conversion system. The catalytic converter includes a catalytic converter housing, a catalytic converter inner tube fitted in a small gap with the catalytic converter housing, and a plurality of catalytic elements for catalyzing exhaust gas. The inner tube of the catalytic converter is provided with a catalytic reaction chamber, and the inner wall of the catalytic reaction chamber is arranged along the exhaust gas flow direction to arrange a plurality of first grooves for placing catalytic elements, and the width of each first groove is the same as that of each catalytic element. thickness to match. Each catalytic element includes a plurality of air flow holes, and the plurality of air flow holes of two adjacent catalytic elements are distributed alternately. The entire catalytic converter is simple in structure, easy to disassemble, and convenient for later operation and maintenance. The catalytic system has high catalytic effect, easy operation, and requires less capital for later maintenance.

Description

technical field [0001] The invention relates to the field of environment, in particular to a catalytic converter and a catalytic conversion system. Background technique [0002] A catalyst is a substance used in a catalytic reaction to change the rate of a chemical reaction without changing the overall standard Gibbs free energy of the reaction. The composition, chemical properties and quality of the catalyst itself do not change before and after the chemical reaction process. [0003] The catalytic efficiency of the existing catalytic device is not high, and the catalyst in the catalytic device is easy to fall off, thereby reducing the catalytic effect of the catalyst on the catalytic reaction. At the same time, the operation is cumbersome when replacing the components in the catalytic device, which consumes a lot of manpower and material resources. At the same time, later maintenance and warranty costs more money. Contents of the invention [0004] The purpose of the ...
