Ultrasonic filtering system and method

Abstract

The invention relates to an ultrasonic filtering system and method. The ultrasonic filtering system comprises a filtering device and a control system. The filtering device comprises a housing 6 whichis provided with an inflow pipe 9, an outflow pipe 12 and a mud discharge pipe 7; the inflow pipe 9 is in reducing structure to turn an inflow of water into a rotational flow; a filter 5 connected with the outflow pipe 12 is arranged inside the housing 6; the inflow pipe 9, the outflow pipe 12 and the mud discharge pipe 7 are provided with an inflow electromagnetic valve 10, an outflow electromagnetic valve 1 and a mud discharge electromagnetic valve 8 respectively; the inflow electromagnetic valve 10, the outflow electromagnetic valve 1 and the mud discharge electromagnetic valve 8 are connected with the control signal output end of the control system; the outer wall of the housing 6 is provided with an ultrasonic transducer 4 which is used for generating ultrasonic wave; the ultrasonic transducer 4 is connected with the control system via a power amplifier 3 and a signal generator 2. The system and method herein have the advantages that fewer impurities gather and accumulate, accumulated impurities can be effectively removed, treatment efficiency is high, and the system and method are energy efficient and environmentally friendly and are low in operation cost.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an ultrasonic filtering system and method. Background technique [0002] Water pollution has become one of the most concerned environmental problems in the world today. With the increasingly serious problem of water pollution, my country's sewage treatment industry has developed rapidly. Pretreatment is an important part of the water treatment process. The degree of raw water pretreatment will directly or indirectly affect the treatment effect of subsequent processes and the quality of effluent water. It is imminent to develop an energy-saving, environmentally friendly, and high-efficiency treatment device for the pretreatment stage of water treatment. [0003] Filtration technology is a treatment technology that is widely used in the pretreatment stage. Traditional ordinary mesh filters are widely used in water source filtration, industrial circulating water systems, s...

Problems solved by technology

However, the immature design scheme and design structure of fully automatic cleaning filters often lead to a large amount of accumulation and deposition of impurities inside the filter, and it is difficult to achieve effective removal of impurities even in the backwashing stage, often unable to ensure continuous and stable operation of the filter , resulting in a serious reduction in filter life and efficiency
