U-shaped foam dust removal device of biomass gas-making furnace and dust removal method of U-shaped foam dust removal device

Abstract

The invention discloses a U-shaped foam dust removal device of a biomass gas-making furnace and a dust removal method of the U-shaped foam dust removal device. The U-shaped foam dust removal device comprises a flue gas pipe and a draught fan, wherein a U-shaped foam dust removal pipe is arranged between a flue gas inlet and a flue gas outlet; a foam nozzle which is communicated with a first foam pipe is arranged at one end, close to the flue gas inlet, of the U-shaped foam dust removal pipe; one end, close to the flue gas outlet, of the U-shaped foam dust removal pipe is communicated with a foam outlet of a second foam pipe; a foam box for accumulating foam is arranged between the first foam pipe and the second foam pipe; the bottom of the U-shaped foam dust removal pipe is communicated with a dust accumulation pipe; a knife-type valve with an upper flange and a lower flange is arranged at the bottom of the dust accumulation pipe; a filter net round frame is arranged at the lower end, located at the foam outlet, of the U-shaped foam dust removal pipe; and a dustproof breathable membrane round frame is arranged at the upper end, located at the foam outlet, of the U-shaped foam dust removal pipe. The U-shaped foam dust removal device is suitable for dust removal of the biomass gas-making furnace, and the efficient and lasting dust removal effect can be reached.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a U-shaped foam dust removal device for a biomass gas generator and a dust removal method thereof. Background technique [0002] Biomass gas-making furnace is a gas-making furnace that replaces coal with biomass fuel such as bamboo and sawdust as raw materials. Since there is no SO 2 Waste gas pollution has developed rapidly in recent years. However, biomass fuels such as bamboo wood chips still produce a large amount of bamboo wood powder and charcoal dust during the gas production process. At present, a dust removal pipe is installed on the flue gas pipe near the biomass gas generator. The left side of the dust removal pipe communicates with the air inlet of the flue gas pipe, and the upper right corner communicates with the gas outlet of the flue gas pipe. The open bottom is submerged in the water tank. In the water, the dust is removed by spray...

AI Technical Summary

Problems solved by technology

Because the dust in the flue gas is extremely fast under the action of the induced draft fan, this single water mist dust removal method is not effective
