Problems solved by technology

The feature of these wet purification devices is that a device for atomizing water is installed in the housing. Although the problem of smoke and dust treatment is better solved, since the dust (large particles) and sulfur-containing gas are treated in the same container, it is difficult for the Larger boilers, especially coal-fired boilers, have the following disadvantages due to the large amount of dust particles: (1) The amount of ash discharge is large, and the wet method increases the difficulty of ash discharge
(2) The amount of water consumed in the granular dust is relatively large, resulting in a waste of water resources and increasing the cost of dust removal
(3) Due to the one-time treatment of dust and flue gas (sulfur-containing gas), the equipment works in a state of strong corrosion and high wear, and the requirements for anti-corrosion treatment of the equipment are high. The cost of making corrosion-resistant stainless steel is high, and the service life of the equipment is relatively long. Low

Abstract

A smoke cleaner for boiler and its cleaning method are discloosed. The smoke from boiler flows through cyclone dust collector for removing dust, hydraulic draught fan, wet dust for further removing dust and sulfuride, and gas-water separator for separating water from gas. The water containing dust powder flows in depositing pool. The gas flows into lime milk in desulfurizer to obtain chean gas for exhausting. Its advantages are high effect and low corrosion to equipment.

Description

1. Technical field [0001] The invention belongs to a domestic and industrial boiler waste gas smoke purification device and a treatment method.
