Raw coke oven gas dust removal device

The utility model relates to a raw coke oven gas dust removal device. The raw coke oven gas dust removal device comprises at least one dust removal unit, wherein the dust removal unit comprises a filter which is respectively communicated with a raw coke oven gas pipeline, a coal gas cooler and a replaced gas pipeline, the coal gas cooler is communicated with a bag-type dust collector which is communicated with an oil-free gas pipeline and a circulating fan, the circulating fan is communicated with a coal gas heater, a purified gas discharging port at the bottom of the filter is communicated with a purified gas discharging pipeline, a blowback gas inlet and a blowback gas pipeline, and the blowback gas pipeline is communicated with a gas change pipeline and the coal gas heater. The raw coke oven gas dust removal device is simple in structure, stable in operation, low in energy consumption and high in filtration efficiency and is not provided with a circulating soot blowing regeneration system; by adopting the raw coke oven gas dust removal device, bed materials do not need to circulate, so that filter materials are prevented from being crushed and wearing equipment in a filtering process; the multiple raw coke oven gas dust removal devices can be connected in parallel and combined for filtration.
