Description
Technical Field
The utility model relates to the technical field of ozone catalytic oxidation reaction, in particular to a movable ozone catalytic oxidation reactor.
Background
The traditional fixed bed ozone catalytic oxidation reaction technology is a common advanced oxidation treatment technology for wastewater, and is mainly used for removing pollutants such as organic matters in the wastewater. Usually, a fixed bed reactor is adopted, the bed layer is filled with catalyst in a stacking way, wastewater contacts ozone through the catalyst bed layer in the reactor, and catalytic oxidation reaction occurs, so that degradation of organic matters is realized. The technology is widely applied in the field of advanced oxidation of wastewater, but has certain defects, and has unsatisfactory effect in some special wastewater treatments. The main problems of the traditional fixed bed ozone catalytic oxidation reaction technology are as follows:
first, the mass transfer of ozone from the gas phase to the liquid phase is limited by the flow pattern of the wastewater in the bed. When wastewater and ozone pass through the catalyst in the bed, a fixed channel is gradually formed due to the influence of resistance, channeling, short flow and dead zone appear, the contact quantity and contact time between the ozone and pollutants are reduced, the utilization rate of the ozone and the catalyst is reduced, and the pollutants are incompletely oxidized and the removal efficiency is low.
Secondly, the catalyst in the reactor is extremely susceptible to scale deactivation in high hardness wastewater. Deposit build-up on the catalyst surface can clog the active sites and reduce the catalytic activity, resulting in rapid decay or even loss of catalyst activity and reduced treatment efficiency.
The packed bed in the reactor may harden or block with the passage of time, causing the phenomena of unsmooth water passing or channeling and short flow, further reducing the effective utilization rate of the catalyst and the ozone mass transfer efficiency, and only intermittent operation and periodical back flushing can be performed. The treated water quality is unstable and periodic fluctuation occurs.
Because the back flushing needs to leave enough catalyst to clean the expansion space, the effective volume utilization rate of the reactor is low, and the investment and the occupied area are increased.
Fifth, because of the need of advancing and switching water and gas pipelines during back flushing, the configuration of the reactor is complex, the manufacturing cost is high, the requirement on automatic control is high, and the maintenance workload is large.
The application range and the effect of the traditional fixed ozone catalytic oxidation reaction technology are seriously affected by the problems.

The patent adopts a continuous automatic cleaning operation mode, effectively reduces the scaling speed of the catalyst, and ensures that the catalyst can still keep the catalyst activity for a long time in high-hardness wastewater.
3. Optimization of system configuration and automation requirements: in the traditional fixed ozone catalytic oxidation reaction technology, the system configuration is complex, the manufacturing cost is high, the requirement on automatic control is high, and the maintenance workload is large. The system configuration and automation requirements of the patent are greatly optimized, so that the system configuration is simpler, the operation is simpler and more convenient, the maintenance is less, and the manufacturing cost is lower.
