Desulfuration and dust-removal purifying device

Abstract

The invention discloses a desulfuration and dust-removal purifying device which comprises a gas inlet channel connected with a flue gas pipeline, wherein the gas inlet channel is connected with a flue gas treating pipeline, an outlet of the flue gas treating pipeline is connected with a gas outlet channel, a gas distributing cone with two thin ends and thick middle are fixedly suspended in the flue gas treating pipeline, a flue gas washing cavity is arranged between the wall of the flue gas treating pipeline and the wall of the gas distributing cone, the inner side of the wall of the gas distributing cone is provided with a washing solution inner cavity, a washing solution outer cavity sealed with the wall of the flue gas treating pipeline is arranged outside the wall of the flue gas treating pipeline, a liquid feeding channel is arranged on the washing solution outer cavity, a cavity communicating channel used for communicating the washing solution inner cavity with the washing solution outer cavity in a sealing manner is arranged between the wall of the flue gas treating pipeline and the wall of the gas distributing cone in a sealing manner, the washing solution inner cavity andthe washing solution outer cavity are filled with washing solutions, and washing solution spraying holes are arranged on the wall of the flue gas treating pipeline and the wall of the gas distributing cone.

Description

technical field [0001] The invention relates to a desulfurization and dust removal purification device, in particular to a flue gas desulfurization and dust removal purification device. Background technique [0002] Due to the rapid development of industry and the continuous increase of population, the consumption of various fuels has increased sharply year by year, and the smoke and dust generated by the combustion of fuels have become increasingly serious pollution to the atmosphere. Especially our country is a big coal-fired country. When the existing coal-fired boilers and furnace cellars are working, there are still a lot of dust and sulfur dioxide in the self-exhausted flue gas. If they are directly discharged into the air, they will cause great harm to the environment. Pollution, the dust contained in the flue gas is suspended in the atmosphere, which has a negative impact on the human respiratory system, atmospheric visibility and urban landscape; the sulfur dioxide ...

Especially our country is a big coal-fired country. When the existing coal-fired boilers and furnace cellars are working, there are still a lot of dust and sulfur dioxide in the self-exhausted flue gas. If they are directly discharged into the air, they will cause great harm to the environment. Pollution, the dust contained in the flue gas is suspended in the atmosphere, which has a negative impact on the human respiratory system, atmospheric visibility and urban landscape; the sulfur dioxide in the flue gas contacts with the water vapor in the air, forming acid rain, thus causing serious harm to human beings. the harm of

Most of the existing desulfurization and dust removal devices are partition dust fall chambers, which are not effective, and there is dust sticking and clogging. Very large, high cost, not conducive to promotion in enterprises
