Problems solved by technology

[0006] As mentioned above, in the device structure expressed in the Chinese patent application with the publication number CN102260003A, the outer wall of the quartz tube used for shielding the electrodeless ultraviolet lamp refers to the outer wall of the quartz tube. The contact with industrial wastewater will inevitably accumulate scale gradually. Of course, the scaled substances are mainly inorganic impurities that are not easily touched by photocatalytic reactions. The scaling phenomenon formed by this mechanism is easy to be observed after the equipment has been running for a long time Although the scale layer attached to the outer wall of the quartz tube is only a thin layer, ...

Abstract

The invention which relates to a scaling-free microwave photocatalytic reactor applied to industrial wastewater degradation processing belongs to the technical field of wastewater processing. According to present microwave photocatalytic degradation technologies aiming at industrial wastewater containing organic pollutants, the outside surface of a quartz tube used for the protection of a non-polar ultraviolet lamp screen in a device scales after being immersed in the wastewater liquid for a long time, and the resulting scaling layer seriously influences the ultraviolet light's permeability of the quartz tube, and causes the great reduction of the processing efficiency of present microwave photocatalytic reactors. The invention aims to solve above problems. According to the invention, an ultrasonic transducer is adhesively arranged on the outside surface of each of side walls of the microwave photocatalytic reactor, ultrasonic waves are emitted to the inside of the reactor, and instant scale removal from the outside surface of the quartz tube is realized through using ultrasonic wave oscillation under non-stop non-disassemble conditions, so the high ultraviolet light's permeability of the quartz tube is maintained, and the continuous high efficiency of the microwave photocatalytic reactor is maintained.

Description

technical field [0001] The invention relates to a fouling-free microwave photocatalytic reaction device applied to the degradation treatment of industrial wastewater, belonging to the technical field of CO2F wastewater treatment. Background technique [0002] Microwave photocatalytic degradation treatment technology, as an effective harmless treatment technology for industrial wastewater containing organic pollutants, has developed rapidly in recent years. [0003] Regarding the microwave photocatalytic degradation technology, as an example, refer to the Chinese patent application with publication number CN102260003A. [0004] The Chinese patent application with the publication number CN102260003A uses microwaves as the excitation source to excite the electrodeless ultraviolet lamp to emit ultraviolet rays, and irradiates the suspension mixed with photocatalyst titanium dioxide inside the liquid. The electrodeless ultraviolet lamp is shrouded and protected by a quartz tube. ...
