Abstract

The invention relates to the technical field of dust removing of power station boiler desulfurizing agent bins, in particular to a device for removing dust of a desulfurizing agent bin and a dust removing method. In the device for removing dust of the desulfurizing agent bin, the tail of a hearth and the desulfurizing agent bin both communicate with an air inlet of a dust remover, an air outlet of the dust remover communicates with an exhaust port through a negative-pressure unit, the negative-pressure unit has a negative pressure function and is used for pumping out and mixing gas-slag mixtures from the desulfurizing agent bin and the hearth, then dust removing is conducted through the dust remover, and therefore the dust removing work on the power station boiler desulfurizing agent bin can be achieved through the device and the dust removing method; and the dust removing process is environment-friendly and safe, and the problems of secondary pollution and powder explosions can be solved.

Description

technical field [0001] The invention relates to the technical field of dust removal for desulfurizer bins of power station boilers, in particular to a device and method for dedusting desulfurizer bins. Background technique [0002] Circulating fluidized bed boilers generally use dry desulfurization, and the commonly used desulfurizers are limestone powder and carbide slag. Its common process is as follows: [0003] The tanker equipped with desulfurizer uses compressed air to transport the calcium carbide slag as a desulfurizer to the desulfurizer bin of the boiler, which is usually arranged in the coal delivery trestle; the air after transporting the calcium carbide slag is dusted by the bag filter and then discharged To the coal trestle. [0004] However, because the high-temperature calcium carbide slag that is usually transported contains moisture, it will condense on the bag of the dust collector after entering the desulfurizer bin, and the bag will be glued to death, ...
