Patent ID: 7938885

Claim:
A device for removing soot dust of fuel oil combustion, comprising: a wet type dust removal-desulfurization device; a water-spray device being set on a top of the wet type dust removal-desulfurization device; a mesh screen having 18-30 layers and 18-30 meshes whose tangent angle to a flow direction of the soot dust ranges from 60° to 90°, wherein the mesh screen is set in the wet type dust removal-desulfurization device; an electrostatic precipitator (ESP)-desulfurization device having an automatic cleaning device and an even-flow board being set on a top of the ESP-desulfurization device, wherein an electrostatic dedusting body is a center part of the ESP-desulfurization device, the ESP-desulfurization device also having a soot dust guiding board mounted on a lower part of the ESP-desulfurization device, further wherein both the even-flow board and the soot dust guiding board evenly regulate the soot dust flowing through the ESP-desulfurization device; and a tank, wherein the wet type dust removal-desulfurization device and the ESP-desulfurization device are connected to an upper part of the tank being separated by a first partition board; wherein a smoke duct is formed above a water interface of the tank, the soot dust of fuel oil combustion flows from the wet type dust removal-desulfurization device into the ESP-desulfurization device for soot dust removal and desulfurization via the smoke duct and the soot dust guiding board.
