Vortex street type cloud and mist air purification device

Abstract

The invention provides a vortex street type cloud and mist air purification device. The vortex street type cloud and mist air purification device comprises a fan, a hollow cylinder, a cloud and mist generator suite, a cloud and mist mixing section, a rectification damping net, an electrode plate, a high-voltage electrode plate, a grounding electrode plate, an electrode plate and the like. By utilizing flow field characteristics of vortex and turbulent flow in cylindrical streaming wake flow and a charged cloud and mist trapping technology, automatic suction of cloud and mist, interaction of charged cloud and mist and fine particles in dust-containing airflow, Brownian motion, suction of coulombic force and coalescence of fine particles and cloud and mist caused by vortex and turbulent flow are realized, and under the coupling action of multiple coalescence forms, liquid drops with relatively large particles are quickly formed and are deposited and recycled under the action of electrostatic force. The PM2.5 removal efficiency is high, the energy consumption is low, the water consumption is low, the structure is compact, and an existing ventilation system can be conveniently transformed.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a vortex street type cloud and mist air purification device. Background technique [0002] In recent years, smog has occurred frequently around the world, and the culprit is the fine particulate matter PM2.5. PM2.5 is mainly composed of water-soluble ions, particulate organic matter and trace elements, and its precursors include sulfur dioxide, nitrogen monoxide, and volatile organic compounds. Studies have found that PM2.5 is easier to accumulate organic pollutants, acidic oxides, toxic heavy metals, bacteria and viruses in the air because of its small particle size and larger specific surface area than PM10. When PM2.5 is inhaled into the human body, it can be produced by breathing into the blood and cause diseases in the human respiratory, endocrine, cardiovascular, nervous and immune systems. At present, there are few suitable methods at home and abroad to prescribe the righ...

Chinese patent CN201610803531.3 "A kind of exhaust gas treatment device and treatment method" adopts an ultrasonic atomization nozzle to make the droplet particle size about 20 microns, and applies sound wave reunion to strengthen the collision reunion rate of liquid droplets and fine particles, due to the energy consumption of sound wave reunion If it is too high, the mechanism of action is not clear enough, and there is still a distance from practical application

Chinese patent CN201520441267.4 "Cloud-type dust removal system" is equipped with a liquid mist generator, a particle growth area and a cloud-type dust removal device. The dust-laden airflow mixes slowly with the liquid mist, and the speed of the dust-laden airflow is relatively small. The whole set of devices is relatively complicated and the structural size Large, its promotion and application are limited

Chinese patent CN 2018103151904 "a cloud-type air purification device", which comprehensively uses the flow characteristics of the wall-attached jet and the rotating jet, ensures that the fine particles in the airflow and the small droplets of the cloud collide, coalesce, and agglomerate. The device is still more complex
