TECHNICAL FIELD
[0001] The present application relates to the technical field of defogging, in particular to a mechanical and electrical integrated wire screen type defogging device and defogging method. BACKGROUND
[0002] The wire screen defogger is used to remove the mist (droplets) entrained in the gas, recover the expensive droplets (valuable materials), or purify the gas to reduce impurities in the gas. The working mechanism is as follows: the fine liquid droplets entrained in the gas phase pass through the wire screen of the wire screen defogger, and the droplets are adhered or adsorbed after colliding with the defogging wire screen. Through repeated adsorption of droplets, the extremely small droplets are agglomerated and coalesced into large droplets. The large droplets move downward along the intersection of the woven wire screen wires under the action of gravity, and continue to adsorb the droplets entrained in the gas. The growing droplets flow to the bottom of the defogging wire screen and fall down by their own gravity. In fact, during the absorption process, the inside of the entire wire screen defogger is filled with adsorbed droplets, which enhances the adsorption capacity of the single metal or engineering plastic wire, so that the defogging rate of the defogging wire screen is greatly improved during normal operation, and the extremely small droplets can be effectively adsorbed and separated and collected.
[0003] During a long defogging process, a large amount of droplets will accumulate in the wire screen, thereby hindering the flow of gas for defogging, and the gas is not evenly distributed in the defogging equipment, which is easy to flow concentratedly at the middle part of the wire screen and the like, thereby aggravating the plugging of the wire screen.

9. A method for demisting using an electromechanical integrated wire mesh demisting device according to any one of claims 1 to 8, characterized in that, Includes the following steps: S1, Defogging: Air is introduced into the housing (1) through the air inlet pipe (3). When the gas passes through the wire mesh (11), the mist droplets carried by the gas are intercepted by the wire mesh (11), so that the demisted gas passes through the wire mesh (11) and enters the air outlet pipe (2). The droplets trapped by the wire mesh (11) drip into the bottom of the shell (1) under the action of gravity and accumulate; S2, Adjustment: When the water level sensor (13) and the controller electrically connected to the water level sensor (13) monitor and analyze the water level rise rate slows down, that is, the efficiency of the wire mesh (11) in trapping mist droplets decreases, the water level sensor (13) transmits a signal to the controller, causing the controller to turn on the forward and reverse motor (513), so that the first rotating rod (5) drives the second rotating rod (51) to rotate through the first transmission belt (512). Then the swing plate (511) on the first rotating rod (5) and the second rotating rod (51) intermittently hits the wire mesh (11) to knock off the residual mist droplets on the wire mesh (11) in order to clean the wire mesh (11). At the same time, the first rotating rod (5) and the second rotating rod (51) drive the fourth rotating rod (53) and the third rotating rod (52) to rotate through the third transmission belt (531) and the second transmission belt (521), respectively, thereby guiding the gas below the wire mesh (11) to both sides of the wire mesh (11) and reducing the air flow in the middle of the wire mesh (11); The fifth rotating rod (54) is driven to rotate by the drive mechanism, so that the fan blade (541) blows the airflow inside the shell (1), accelerates the demisting and discharge of the gas, and thus reduces the air pressure inside the shell (1).
