Description

Ultrasonic sewage treatment device Technical Field The invention relates to the technical field of sewage treatment, in particular to an ultrasonic sewage treatment device. Background An ultrasonic sewage treatment device is an advanced environment-friendly device for efficiently treating various sewage and sludge by utilizing the physical and chemical principle of cavitation effect generated by ultrasonic waves in liquid. It generates high-frequency sound wave in the liquid to form countless tiny bubbles and make them burst violently instantaneously, so as to generate local high-temperature high-pressure, thus decomposing pollutant. The core is cavitation effect and free radical oxidation. In short, when ultrasonic waves propagate in sewage, a large number of tiny "cavitation bubbles" are generated. These bubbles vibrate vigorously under the influence of a sound field and eventually burst instantaneously, producing local high temperatures up to 5000 ℃ and instantaneous high pressures in excess of 50 mpa. The extreme physical conditions can directly break the chemical bond of the pollutant, and degrade toxic and harmful organic matters into carbon dioxide, water or harmless small molecular substances. Meanwhile, the cavitation effect can generate free radicals (such as hydroxyl free radicals) with extremely strong oxidizing capability, and further oxidizing and decomposing pollutants. In addition, the mechanical effect, the thermal effect and the like are synergistic, and the treatment effect is enhanced. The traditional ultrasonic sewage treatment device regards the transducer and the reactor body as an integrated structure, and the installation mode of the transducer mainly comprises three modes of side wall fixing, bottom flange fixing and immersed installation. The installation mode is a non-detachable rigid connection structure, and the transducer and the reactor body are fixed through welding, sealant bonding and other modes, namely, the transducer is fixedly connected to the equipment body and cannot be detached conveniently. In the actual industrial application process, the transducer is in a sewage medium for a long time and is easy to scale by impurities in sewage and corrode corrosive substances, and performance attenuation or damage can be caused by long-term high-frequency operation. Because the transducer and the reactor body are of undetachable structures, when the transducer is in scale formation, corrosion, damage and other faults and needs to be replaced, the sewage in the reaction tank body must be completely emptied, and then a large number of pipelines and accessory parts connected with the reactor body are disassembled, so that the detachment and replacement of the transducer can be realized. This maintenance process not only complex operation, consuming time are hard, lead to sewage treatment system to shut down for a long time, influence treatment effeciency, can also show increase equipment maintenance cost, and the evacuation jar body, the process of dismantling the pipeline also have certain operational risk simultaneously, can't satisfy high-efficient, convenient, low-cost equipment maintenance demand in the industrial production. Based on the above, the invention provides an ultrasonic sewage treatment device. Disclosure of Invention The invention aims to provide an ultrasonic sewage treatment device which solves the problems.
