Probe type ultrasonic device for breaking sludge

Abstract

The invention provides a probe type ultrasonic device for breaking sludge, which consists of a sound energy generator, an energy transducer, an ultrasonic probe, a vertical chute and a soundproof box. The sound energy generator has a box body structure, is connected with the energy transducer, and comprises a cooling system, a power controller and a time controller. The energy transducer has a stainless steel cylindrical structure, while the ultrasonic probe has a titanium alloy MS73 cylindrical structure, one end of the probe is connected with the energy transducer, while the other end is positioned in the vertical chute. The front end of the vertical chute is a sludge inlet and the back end is a sludge outlet, and the front end in the chute is provided with a sludge baffle plate to increase the staying time of the sludge in the chute. The whole energy transducer, the ultrasonic probe and the vertical chute are completely arranged and sealed in the soundproof box. The soundproof box is connected with a support to form an airtight fixing device for the convenience of carrying and displacement.

Description

Technical field [0001] The invention relates to sewage treatment equipment, in particular to a cracking device for excess sludge pretreatment. Background technique [0002] The back-end treatment of excess sludge usually includes concentration and dehydration, anaerobic digestion and return to aerobic aeration system for biological reprocessing. However, the hydrophilic nature and floc structure of activated sludge make the dehydration process very difficult, and the microbial The presence of large amounts limits the reaction rate of the hydrolysis stage of anaerobic digestion, resulting in long digestion residence time, bulky digester body, and low methane production. Studies have shown that sludge disintegration can effectively promote sludge reduction, improve dewatering performance, increase anaerobic digestion hydrolysis rate and increase methane production. Crack the sludge structure and cell wall, make the sludge floc structure change, the intracellular contents flow...
