The existing flue gas purification system generally adopts an inertial interception mechanism to capture liquid drops, and is characterized in that the capture efficiency of the liquid drops with micron granularity is low, and the mist capturing process brings remarkable resistance to air flow, so that the energy consumption of a fan is increased. In order to recover the water vapor, the industry often adopts a scheme of matching a condenser with a flue gas purifying system. However, dust which is not thoroughly removed exists in the flue gas, so that the problem of dust accumulation and scaling of the condenser is serious, and the heat transfer efficiency of the flue gas and the condenser is further affected. In addition, the condenser needs to be used with a cooling tower, and the operation process of the cooling tower often discharges water vapor to the atmosphere, thereby causing water loss. In order to recover the water vapor in the flue gas, a few industrial processes adopt a liquid hygroscopic agent atomizing mode to absorb the water vapor in the flue gas, but the scheme has the problem that atomized hygroscopic agent drops escape from an outlet of an absorption device.
Therefore, there is an urgent need in the industry for more efficient recovery techniques for droplets and water vapor in flue gas. At present, the water resource pollution problem in China is serious, and the water resource shortage problem is increasingly serious. The development of a technology facing the water recovery requirement in flue gas or cooling tower exhaust is of great significance.

The device is only based on the condensation principle to capture the water vapor, the cooling effect on the flue gas is only 3-5 ℃, the condensation amount of the water vapor is limited, the flow of circulating water in the gas-liquid heat exchanger needs to be powered by a pump, and the cooling of the circulating water needs to be provided with an additional heat exchanger. Furthermore, the device is unable to capture droplets suspended in the flue gas. Therefore, the device has lower efficiency of capturing water resources in the flue gas, and the energy consumption and the complexity of the water taking system are higher.

When the voltage to which the discharge electrode 14 is connected is in a proper range, corona discharge occurs, and ion wind is generated, although the repulsive electrode 13 is connected with high voltage, the repulsive electrode 13 does not generate corona discharge, only the electric field distribution in the device is regulated, the air flow 16 containing the moisture absorbent liquid drops 17 entering through the moisture absorption fog inlet 2-3 is mixed with the flue gas or cooling tower exhaust 18 entering through the air inlet 2-2 in the electrostatic defogging water intake device 2, the moisture absorbent liquid drops 17 and the fog drops 19 contained in the flue gas or cooling tower exhaust 18 are charged when migrating to the area near the discharge electrode 14, then migrate to the collecting electrode 15 to be captured under the action of the electric field force, and the moisture absorbent liquid drops 17 migrate in the device and absorb water vapor in the air flow 16. In addition, the flue gas or cooling tower exhaust 18 is mixed with the air stream 16 and then exchanges heat with the air through the collecting electrode 15, so that the water vapor in the air stream 16 is condensed. Ion wind generated by corona discharge exists on two sides of the collecting electrode 15, and the ion wind has strengthening effect on the condensation process of water vapor.
The working principle of the utility model is as follows:
the hygroscopic agent atomizer 1 atomizes a hygroscopic agent solution (such as CaCl 2 Solution) atomized into droplets 17 of a hygroscopic agent having a diameter of about 10 microns, the air stream 16 carries the droplets 17 of the hygroscopic agent into the electrostatic mist-capturing and water-taking device 2 through the hygroscopic mist inlet 2-3, and mixes with the flue gas or cooling tower exhaust 18 entering through the air inlet 2-2 of the electrostatic mist-capturing and water-taking device 2, and the droplets 17 of the hygroscopic agent absorb water in the flue gas or cooling tower exhaust 18The vapor, and subsequently the moisture absorbent droplets 17 are charged by the corona discharge and further captured by the grounded collecting electrode 15 in the electric field, and the mist droplets 19 contained in the flue gas or the cooling tower exhaust 18 themselves are also charged by the corona discharge and the electric field and then captured by the collecting electrode 15 as are the moisture absorbent droplets 17. Meanwhile, the flue gas exchanges heat with the air at the exhaust port 2-1 of the electrostatic mist-capturing water taking device 2 through the collecting electrode 15, so that water vapor in the flue gas is condensed on the surface of the collecting electrode 15. Through the process, mist drops and water vapor in the flue gas can be captured, flue gas subjected to electrostatic mist capturing water taking treatment or cooling tower exhaust 10 flows into ambient air 20 from an exhaust port 2-1 of an electrostatic mist capturing water taking device 2, mist drops and condensed water captured by a collecting electrode 15 in the electrostatic mist capturing water taking device 2 are mixed with moisture absorbent drops 17 to form low-concentration moisture absorbent solution, the low-concentration moisture absorbent solution then enters a moisture absorbent regenerator 8, the moisture absorbent solution is released through a desorption process, the concentrated moisture absorbent solution is formed and returns to the moisture absorbent atomizer 1 through a moisture absorbent circulating pump 7, the water vapor generated by the moisture absorbent regenerator 8 enters a condenser 6 through a water vapor pipeline 11 to be condensed into water, then enters a condensation water tank 9 through a condensed water pipeline 12, heat required by the moisture absorbent regenerator 8 is provided by a heat storage 5, and heat in the heat storage 5 is derived from waste heat generated by power generation of a photovoltaic panel 3. The photovoltaic panel 3 and the heat reservoir 5 realize heat exchange through a water cooling system, cooling water absorbs heat when flowing through the back of the photovoltaic panel 3, and then enters the heat reservoir 5 through a water circulation pipeline to release heat, so that heat is transferred from the photovoltaic panel 3 to the heat reservoir 5.
