A device and method for defogging and water collection based on the coupling of ion wind and vibrating wire grid

Abstract

The invention discloses a demisting water collection device and method based on the coupling of ion wind and vibrating wire grid, which belongs to the field of environmental protection, and specifically includes a high-voltage electrode, a ground electrode, a vibrating wire grid, a negative DC high-voltage power supply, an air flow channel, and an insulating support and the water collection tank; the insulating pillars are used to suspend the high-voltage electrodes, and the vibrating wire grid is driven by the airflow carrying the droplets to vibrate, so that some droplets collide and flow out along it; an electric field area is formed between the ground electrode and the high-voltage electrode, which is opposite to the direction of the airflow. The ion wind makes the air flow and the ion wind form an intersection surface; the negative DC high-voltage power supply is used to provide adjustable voltage for the high-voltage electrode, so that the intersection surface is located at the ground electrode, and the remaining droplets flow out along it; the water collection tank is used for Collect the mist droplets flowing from the vibrating wire grid and the ground electrode. The present invention has collected fog droplets twice, and compared with the traditional water collection method, the present invention has higher efficiency of demisting and water collection.

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...
