Abstract
The utility model relates to a baffling multiple-contact-surface catalytic converter. A catalytic oxidizer carrier component is arranged in a housing, and honeycomb holes are formed in the cross sections of the catalytic oxidizer carrier component and penetrate through the catalytic oxidizer carrier component. The catalytic oxidizer carrier component is divided into multiple segments in the housing, and a gap exists between every two adjacent segments. The honeycomb holes of the adjacent segments of the catalytic oxidizer carrier component are staggered, and a gap exists between the periphery of the catalytic oxidizer carrier component and the inner wall of the housing. The thickness of the catalytic oxidizer carrier component is not larger than 1/3 of the length of the housing, and the gap between every two adjacent segments of the catalytic oxidizer carrier component is 1/2 of the thickness of the catalytic oxidizer carrier component. Two layers of division plates with through holes are arranged in the middle of each gap, and through holes in the division plates are staggered. A catalytic oxidizer is coated in the honeycomb holes and on the surfaces of the division plates, the inner wall of the housing and the surface of the catalytic oxidizer carrier component. The bond area of the catalytic oxidizer increases, the standing time of tail gas in the housing is prolonged, and the catalytic oxidation rate of the tail gas is improved.
