A Recyclable High Efficiency Composite Ultrasonic Filter

Abstract

The invention discloses a recyclable high-efficiency composite ultrasonic filter. Including the shell, filter element and fan, the filter element is equipped with an ultrasonic transducer, and the ultrasonic transducer is placed in the middle of the filter element; the filter element includes three layers of composite filter paper, wave paper and ultrasonic transducer, and the three layers of composite filter paper are arranged in an S shape Arranged in curls, the three-layer composite filter paper is arranged with corrugated paper between the adjacent layers after S-shaped curling, and the ultrasonic transducer is placed on the corrugated paper in the middle of the filter element. The three-layer composite filter paper is made of glass fiber, activated carbon fiber and glass It is prepared by mixing cotton; it also includes an ultrasonic cleaning filter module, and the ultrasonic cleaning filter module includes an ultrasonic probe and an electrostatic membrane. The invention enhances the filtering effect of the filter element, and at the same time enables the filter element to have dual functions of filtering particles and removing harmful gases such as formaldehyde; the arrangement of the ultrasonic device improves the filtering efficiency, and enables the filter element to be used repeatedly, increasing the service life of the filter element .

Description

technical field [0001] The invention relates to an air filter, in particular to a recyclable high-efficiency composite ultrasonic filter. Background technique [0002] With the vigorous development of modern industry, the society has made rapid progress, and people's living standards have also been rapidly improved, but what follows is the deterioration of the ecological environment, and the nature and distribution of air dust have also changed. In December 2013, smog swept across the land of my country, covering half of our country in a sea of ​​smog. The air quality (AQI) hit new highs repeatedly, and the PM2.5 value also frequently exceeded the table. At the beginning of 2014, a new round of smog hit again, affecting a land area of ​​about 1.43 million square kilometers, of which the area of ​​heavy smog was about 810,000 square kilometers, and the heavily polluted weather in Beijing lasted for more than 90 hours. The smog weather brings a lot of inconvenience to people'...

AI Technical Summary

Problems solved by technology

[0005] (1) Simply using glass fiber paper for filtration, the transmittance of particulate matter is relatively high, and the purification effect cannot be achieved

[0006] (2) In order to achieve the dual effects of removing particulate matter and harmful gases, most filters use glass fiber paper filter screens and activated carbon filter screens to remove particulate matter and harmful gases respectively, but the use of multi-layer filter screens will cause the volume of the filter to change. Big

[0007] (3) The filter screen in the air filter is disposable, and some filter screens need to be replaced after less than three months of use, and the service life ranges from 3 to 18 months, which not only increases the user's use cost, but also causes The waste of resources is an indirect environmental pollution
