Abstract
Disclosed are an electrostatic precipitator system and method. The disclosed electrostatic precipitator system includes: an electrostatic precipitator; a main hopper which is disposed below the electrostatic precipitator so as to be in fluid communication with the electrostatic precipitator; a plurality of sub-hoppers disposed below the main hopper so as to be in fluid communication with the main hopper; a vertical duct disposed below each sub-hopper so as to be in fluid communication with each sub-hopper; and a water tank disposed below the vertical duct so as to be in fluid communication with the vertical duct.
Claims10
An electrostatic precipitation system comprising:
- an electrostatic precipitator;
- a main hopper disposed below the electrostatic precipitator and disposed to be in fluid communication with the electrostatic precipitator;
- a plurality of sub-hoppers disposed below the main hopper and disposed to be in fluid communication with the main hopper;
- a vertical duct disposed below each of the sub-hoppers and disposed to be in fluid communication with each of the sub-hoppers;
- and
- a water tank disposed below the vertical duct and disposed to be in fluid communication with the vertical duct, wherein each of the plurality of sub-hoppers has an angle of repose that securely receives all dusts descended from the main hopper without leaking outside of each of the sub-hoppers and at the same time, allows the received dusts to smoothly descend along inner walls of each of the sub-hoppers without accumulating on the inner walls by gravity alone, wherein the electrostatic precipitation system does not comprise a dust fall-hindering member between the main hopper and the water tank.
An electrostatic precipitation method comprising:
- a step (S10) of supplying an exhaust gas of high temperature of 300° C. or more to an electrostatic precipitator, and separating dusts from the exhaust gas, thereby generating clean gas;
- a step (S20) of transferring the dusts separated in the step (S10) to a main hopper by gravity;
- a step (S30) of transferring the dusts transferred to the main hopper in the step (S20) to a plurality of sub-hoppers by gravity;
- a step (S40) of transferring the dusts transferred to each of the sub-hoppers in the step (S30) to a vertical duct by gravity;
- and
- a step (S50) of introducing by gravity, into a water tank, the dusts transferred to each of the vertical ducts in the step (S40),
- wherein each of the plurality of sub-hoppers has an angle of repose that securely receives all of the dusts descended from the main hopper without leaking outside of each of the sub-hoppers and at the same time, allows the received dusts to smoothly descend along inner walls of each of the sub-hoppers without accumulating on the inner walls by gravity alone, and
- wherein the steps (S20) to (S40) are configured to allow the dusts separated in the step (S10) to fall to the water tank by gravity without being hindered by a dust fall-hindering member.
