Demisting and water collecting device and method based on coupling of ionic wind and vibrating wire grid

Abstract

The invention discloses a demisting and water collecting device and method based on coupling of ionic wind and a vibrating wire grid, belongs to the field of environmental protection, and particularlycomprises a high-voltage electrode, a ground electrode, a vibrating wire grid, a negative direct-current high-voltage power supply, an airflow channel, an insulating strut and a water collecting tank. The insulating support column is used for hanging a high-voltage electrode, and the vibrating wire grid vibrates under the driving of airflow carrying fog drops, so that part of fog drops collide and flow out along the vibrating wire grid; an electric field area is formed between the ground electrode and the high-voltage electrode to generate ionic wind opposite to the airflow direction, so thatan intersection surface is formed between the airflow and the ionic wind; the negative direct-current high-voltage power supply is used for providing adjustable voltage for the high-voltage electrode, so that the intersection surface is positioned at the ground electrode, and residual fog drops flow out along the intersection surface; and the water collecting tank is used for collecting fog dropsflowing out of the vibrating wire grid and the ground electrode. Through two times of fog drop collection, compared with a traditional water collection mode, the demisting and water collection efficiency of the invention is higher.

Description

technical field [0001] The invention belongs to the field of environmental protection, and more specifically relates to a demister and water collection device and method based on the coupling of ion wind and vibrating wire grid. Background technique [0002] Modern industrial production will produce a lot of harmful fog, which has caused great pollution to the environment; for some arid and foggy areas, fog water is also an effective water resource, so how to collect fog water has become a key issue to solve industrial and environmental problems . At present, the commonly used demister and water collection devices are inertial demister, centrifugal demister and electrostatic demister. [0003] Among them, the inertial demister is to change the airflow velocity and airflow direction, so that the larger mist droplets in the airflow will collide with the wall due to their own inertia, and finally condense into droplets and be collected. However, this method is only applicable...
