Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a hydraulic cavitation device for sludge wall breaking. Background Art

[0002] Sewage treatment equipment usually includes multiple treatment units such as pretreatment, biochemical treatment, sedimentation / filtration, and disinfection. The membrane bioreactor is equipped with membrane components for microbial implantation and aeration equipment to increase the dissolved oxygen rate. As the use time increases: 1. The membrane components will be covered with a large amount of solid particles, grease and other impurities, affecting the microbial treatment efficiency on the membrane components; 2. Organic pollutants will breed in the membrane bioreactor, and the use of chemical agents for disinfection will lead to increased costs, environmental pollution and human health; 3. The aeration system in the membrane bioreactor not only consumes a lot of electricity, but is also prone to blockage, which will lead to membrane pool pollution, and may eventually cause equipment corrosion and impurity deposition.

[0003] With the emergence of hydraulic cavitation technology, a more advanced, environmentally friendly and efficient solution is provided for the above problems of membrane bioreactors. This technology is based on the principle of liquid dynamics. By controlling the size and shape of slits or pores, the local pressure of the liquid is reduced when it flows at high speed. When the pressure is lower than the saturated vapor pressure of the liquid, a large number of cavitation bubbles that continue to collapse will be generated. When the cavitation bubbles collapse, they will form high-energy impacts and jets on the surrounding liquid, which can separate solid particles, grease and other impurities from the water. At the same time, under the action of this high energy, the liquid is cracked into active oxygen atoms and hydroxyl free radicals, and recombined to form hydrogen peroxide. The free radicals have strong oxidizing properties and can effectively degrade organic pollutants, biodegradable substances, and increase the dissolved oxygen rate. Compared with the aeration system, it consumes less power and is not prone to blockage and other problems. However, the existing hydraulic cavitation generator has an unreasonable structural design, insufficient liquid lift, resulting in insufficient flow speed, and a small number of cavitation bubbles, resulting in poor impurity removal effect and insufficient dissolved oxygen rate in the membrane bioreactor.

[0004] For example, in a patent of a hydraulic cavitation device and its sewage treatment equipment (Announcement No.: CN117361686A), it includes a shell with a bubble feeding chamber, a water inlet and a water outlet are respectively provided at the bottom and top of the shell, a rotating impeller is provided in the bubble feeding chamber, a filter screen is provided at the water inlet, a venturi tube is provided at the water outlet, and a porous plate is provided at the outlet of the venturi tube. The sewage treatment equipment includes a grid pool, a regulating pool, an anaerobic pool, an anoxic pool, an aerobic pool, a membrane biological reactor and a clear water pool arranged in sequence, and a hydraulic cavitation device is installed at the bottom of the membrane biological reactor. The position and structure of the water inlet and the water outlet are reasonably designed, the liquid travel path is short, the flow rate consumption is low, and the rotation of the rotating impeller can provide a strong lift for the liquid, provide a higher flow rate and pressure for the liquid, increase the liquid flow rate, promote the generation of a large number of bubbles, ensure the dissolved oxygen effect and impurity removal effect, aeration has no dead angle, and the bubble hole is not easy to be blocked.

[0005] The above patent increases the liquid flow rate by rotating the impeller and the venturi tube, promotes the generation of a large number of bubbles, and ensures the dissolved oxygen effect and impurity removal effect. In daily use, due to the installation of the venturi tube, the power required for the rotating impeller to rotate is of a certain intensity, and the bubbles generated by the holes on the impeller rotating in the water flow are limited, which affects the number of hydroxyl groups generated and reduces the wall breaking efficiency of the device. Therefore, it is necessary to invent a hydraulic cavitation device for sludge wall breaking to solve the above problems. Utility Model Content
