Abstract

The utility model discloses direct catalytic combustion equipment which comprises a shell, wherein a catalytic combustion chamber is arranged in the shell, a heat exchange component is fixedly communicated with an exhaust outlet and an air inlet of the catalytic combustion chamber, a filtering box body is fixedly arranged on one side of the top of the shell, a mixing pipe is jointly arranged between the filtering box body and the heat exchange component, and an air inlet pipe is arranged on the mixing pipe. According to the utility model, the problems of high mixing energy consumption and insufficient mixing effect in the prior art are effectively solved by optimizing the structural design of the mixing pipe. Specifically, a layout that thick pipes and thin pipes are alternately connected is adopted, a high-speed turbulence is formed at the thin pipes by utilizing the hydrodynamic effect generated by pipe diameter change, and meanwhile, a slow flow area is formed at the thick pipes, so that the periodic change of the air flow speed is realized. The impeller component arranged in the tubule spontaneously rotates under the action of the flow of the waste gas, so that a strong vortex mixing effect is generated.
