Description

Technical Field

[0001] The utility model relates to the technical field of slag discharge and dust removal structures of boiler slag coolers, in particular to an environmentally friendly slag discharge and dust removal device for boiler slag coolers. Background Art

[0002] Slag cooler is also called slag cooler. Slag cooler is mainly composed of cylinder, slag inlet box, slag outlet box, power transmission device, chassis and electrical control system. The cylinder and partition frame adopt water-cooled wall structure. Slag guide plates are welded on the inner wall of the cylinder and the partition frame. Boiler slag removal (boilerslagremoval) must discharge slag continuously to ensure the continuous and safe operation of the boiler. Most boilers use solid slag removal, and a few use liquid slag removal. The amount of slag removal is related to the boiler capacity, coal type and combustion method. Dust and flue gas are inevitably generated during the use of the boiler. Boiler dust removal is to separate the dust in the boiler from the flue gas, thereby reducing dust pollution and facilitating further desulfurization and denitrification of the flue gas. With the development of society, environmental protection has received more and more attention from people, and boiler dust removal has also been applied to various fields such as thermal power generation.

[0003] At present, an environmentally friendly boiler slag cooler slag removal and dust removal device generates a large amount of fine ash during the continuous slag removal process due to the repeated circulation of coal in the furnace. The fine ash is mixed in the slag and is discharged through the slag outlet after heat recovery by the slag cooler. When the slag is discharged, the hot fine ash expands to form dust, which fills the air and pollutes the working environment. Therefore, those skilled in the art provide an environmentally friendly boiler slag cooler slag removal and dust removal device to solve the problems raised in the above background technology.
