Large-capacity microwave photocatalytic wastewater degradation device with self-checking main cause of reunion

Abstract

The invention relates to a high-capacity microwave photocatalytic wastewater degradation device capable of automatically detecting main agglomeration incentives, belonging to the technical field of wastewater treatment. The following problems exist in the prior related art: the catalyst intercepting link is weaker, the single-tank wastewater treatment capacity of the reactor is smaller, the internal high cyclic strength of liquid is insufficient, the degradation reaction endpoint is difficult to distinguish, catalyst agglomerates can not be dispersed in situ by strong force, and occurrence of catalyst agglomeration can not be perceived immediately. The invention aims to solve the problems once. The structure of the device limits the microwave irradiation airspace, allows substantial capacity expansion of the reactor, reinforces internal high circulation of liquid, can guide release of the bubble flow toward the key reaction areas, can finely intercept the catalyst particles, can disperse the catalyst agglomerates in situ by strong force, simultaneously carries out ultrasonic cleaning on quartz tubes incidentally, can automatically turn off the related power supply when the degradation reaction reaches the endpoint, and can automatically detect main catalyst agglomeration incentive parameters and actively give an alarm when the parameters exceed the standard.

Description

Technical field [0001] The invention relates to a large-capacity microwave photocatalytic waste water degradation device capable of self-checking the main cause of agglomeration, belonging to the technical field of CO2F waste water treatment. Background technique [0002] Microwave photocatalytic degradation treatment technology, as an effective harmless treatment technology for industrial wastewater containing organic pollutants, has attracted much attention 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 publication number CN102260003A uses microwaves as the excitation source to excite an electrodeless ultraviolet lamp to emit ultraviolet rays, and irradiate a suspension containing photocatalyst titanium dioxide particles into the liquid. The electrodeless ultraviolet lamp is protected by a quartz tube. T...

AI Technical Summary

Problems solved by technology

As mentioned earlier, when some pH values ​​are not pre-adjusted in place and the pH value is inappropriate, titanium dioxide particles are prone to agglomeration, which will affect its effective working interface area and affect its photocatalytic performance; especially for the CN102260003A proposal. Those relatively small particle size sections in the applicable catalyst particle size range are more prone to agglomeration problems caused by improper pH value pre-adjustment and inappropriate pH value; for this kind of catalyst particle agglomeration , it is necessary to take effective measures immediately to carry out the deagglomeration operation for the agglomerates; based on the structure of the CN102260003A scheme, the operator cannot immediately detect the agglomeration inside the reactor, and thus cannot make immediate disposal, thus , the limited efficiency of the reactor which can only be a small-scale structure due to many factors will be further reduced; therefore, in the application and operation of the reactor, especially, for example, in the possible large reactor or giant reaction In the application and operation of reactors, how to instantly perceive the main parameters that cause catalyst particles to agglomerate inside the reactor is a key issue. This is the eleventh issue.
