Flue gas moisture recovery device based on heterogeneous charges and working method of flue gas moisture recovery device

Abstract

The invention discloses a flue gas moisture recovery device based on heterogeneous charges and a working method thereof, and belongs to the technical field of flue gas water saving. The condensing device, the turbulence device and the demisting device are sequentially arranged in the shell from an inlet to an outlet; a flow channel between the condensing device and the turbulence device is equally divided into two parts, a positive charge charging device is arranged in one part of the flow channel, and a negative charge charging device is arranged in the other part of the flow channel; a flue gas detection unit is arranged at an inlet of the shell; a charge monitoring device is arranged at an outlet of the shell; a trapezoidal water collecting structure is arranged at the lower part of the shell, and a condensate water recycling device and a charged coagulation water recycling device are respectively arranged at the tail ends of two bevel edges of the trapezoidal water collecting structure. The device is compact in structure, low in energy consumption and capable of efficiently recovering moisture in flue gas.

Description

technical field [0001] The invention belongs to the technical field of flue gas water saving, and in particular relates to a flue gas moisture recovery device based on heterogeneous charging and a working method thereof. Background technique [0002] The northern area has more coal and less water, and most of the industrial flue gas is saturated. Recovering the moisture in this saturated flue gas can slow down the drought in the northern area and eliminate the generation of white fog to avoid polluting the surrounding environment. The influence of power facilities, the formation of ice on electrical equipment by white fog in the severe cold climate, constitutes a major safety hazard, and poses a threat to the safe operation of electrical equipment. [0003] The water mist, droplets and particles in the flue gas are difficult to capture under the influence of aerodynamics, and only the mist eliminator cannot effectively remove the water carried in the flue gas; Efficient col...
