Embodiment Construction

[0034] Arrange the vibrating plate 2 with the built-in ultrasonic electroacoustic transducer in the frame of the water surface of the sedimentation tank 1. The ultrasonic electroacoustic transducers 3 in the vibrating plate are arranged in rows and columns, and are grouped and connected in parallel. The arrows indicate the water inlet and outlet direction. When the water to be settled enters the sedimentation tank from the water inlet direction, the high-frequency current frequency modulation device 8 supplies the high-frequency current to the electro-acoustic converter 3, and controls and adjusts the frequency of its high-frequency current so as to control the electro-acoustic transducer to make it Accelerated settling works best. When the ultrasonic waves reach the bottom of the pool, most of the wave energy is absorbed by three layers of materials of different materials, which are the upper layer of polyester fiber 6, the middle layer of porous polyester foam plastic 5, and...

Abstract

A method of applying ultrasonic wave energy to accelerated sedimentation of suspended matter. The scheme is to direct the sounding surface of the ultrasonic electro-acoustic transducer to the water surface and fix it in a closed container forming a plate structure outside, and link several vibration plates with mechanical locks that are easy to disassemble in the sedimentation area. The electroacoustic transducers inside the vibrating plate are arranged in rows and columns, and the wiring is connected in parallel, so that the electroacoustic transducers arranged in different odd and even numbers can be used to control or reverse the sound of different or the same frequency according to the characteristics of suspended solids in the water. Ultrasound; in order to effectively absorb ultrasonic energy, the bottom layer of the sedimentation tank is made of asphalt mineral wool felt, followed by porous polyester foam, and the upper layer is made of polyester fiber. In order to reduce the interference of reflected waves, the bottom of the pool can be set as a reflecting slope. Make the vertical downward wave form a certain angle with the reflected wave to prevent the interference of the reflected wave.

Description

[0001] Technical field [0002] The invention belongs to the field of water treatment technology, and it can be used in various waterworks and sewage plants for sedimentation treatment technology, and can also be used for other water treatment sedimentation technology, such as river channel water, swimming pool water purification and other sedimentation technology. It is a method of accelerating the sinking of suspended matter by using ultrasonic waves to emit high-frequency waves in the water to be settled to generate acceleration amplitudes. Background technique [0003] Sedimentation technology is an important part of the modern water treatment process, and the traditional precipitation process is to inject the raw water into the sedimentation tank after the mixed reaction with the medicine, so that the enlarged suspended solid molecular clusters can be precipitated by natural gravity. Its disadvantage is that it takes a long time, so that the surface area and volume of the...
