Ozone degradation device based on high-speed airflow and catalyst gas-solid coupling

Abstract

The invention provides an ozone degradation device based on high-speed airflow and catalyst gas-solid coupling. The ozone degradation device comprises an air inlet duct serving as a pipeline for inputting airflow; an annular reaction cavity which is a closed space for ozone decomposition, wherein a catalyst for ozone decomposition is placed in the annular reaction cavity, the annular reaction cavity comprises an inlet connected with the air inlet duct and an annular guide ramp extending along the inlet, and an outlet for discharging purified air flow is formed in the guide ramp; a shaking device which is used for preventing the catalyst from being discharged from the outlet and comprises a support structure mounted outside the outlet and a filter screen sleeving the support structure; an eccentric wheel which is connected with the support structure; and a vibrating motor, wherein the eccentric wheel is driven to shake off the catalyst adhered to the filter screen through the vibratingmotor. Ozone flow enters the annular reaction cavity at a high speed through a high-power fan, the contact rate of a catalyst and the ozone flow is increased while ozone activation energy is reduced under the action of high-speed impact of the flow, and low-cost and high-efficiency degradation of ozone is realized.

Description

technical field [0001] The invention relates to the field of ozone decomposition, in particular to an ozone degradation device based on gas-solid coupling of high-speed airflow and catalyst. Background technique [0002] The high-altitude ozone layer is the protective umbrella of the earth, but the ozone in the troposphere is extremely harmful to the earth's environment and human health. In the past 20-30 years, the global ozone pollution concentration has increased significantly, and the rise in East Asia is faster, and the growth rate is much higher than other regions in the world. Therefore, the efficient degradation of ozone is an urgent problem to be solved. [0003] At present, compared with the ozone methods such as adsorption and absorption, the catalytic ozone decomposition method has become the mainstream research direction in the ozone degradation method due to its advantages of stability and safety. However, the current catalytic method mainly uses the catalyst...
