Bauxite sintering furnace dust-removing purification device

Abstract

The invention discloses a bauxite sintering furnace dust-removing purification device. Smoke dust generated in the bauxite sintering process is intensively delivered into a spraying temperature-reducing dust remover to reduce temperature and remove dust so as to complete primary temperature-reducing and dust-removing process; the smoke dust processed with temperature reduction and dust removal is led into a lime water smoke dust filtering tank by a high-pressure blower to be atomized and purified by lime water so as to complete the second-time purification processing of the smoke dust; the smoke dust processed with secondary purification is led into an atomizing and purifying neutralization reaction tank, and a right amount of purification processing media are added into atomized water inside a main spraying system of the atomizing and purifying neutralization reaction tank to subject to neutralization reaction with harmful gases contained in the smoke dust so as to complete the third-time dust-removing and purification processing of the smoke dust, thereby the invention realizes the discharge of burnt gas reaching the standard, reduces the discharge amount of carbon dioxide and has no harmful gas discharged into air so as to achieve the purpose of energy saving and environmental protection.

Description

technical field [0001] The invention relates to the field of a wet dust removal and purification device matched with a bauxite ore sintering kiln. Background technique [0002] Bauxite is a natural ore, and its sintered products are widely used in the fields of metal processing, refractory materials, cement manufacturing, and abrasives. In the prior art, the sintering processing facilities for bauxite mainly include direct coal-fired sintering kiln, gas generator sintering kiln and other types; since the waste gas and smoke generated in the production and application of direct coal-fired sintering kiln have not passed through any Disposal, directly discharged into the atmosphere, is more harmful to the environment and has been banned by the government. [0003] Although the gasifier sintering kiln has changed the way of burning raw coal, it still has not solved the problem of disposal and emission of harmful substances in the smoke. The wet dust collector used in conjuncti...

[0003] Although the gasifier sintering kiln has changed the way of burning raw coal, it still has not solved the problem of disposal and emission of harmful substances in the smoke and dust

The wet dust collector used in conjunction with the sintering kiln of the gas generator only uses water mist spraying to reduce the emission of smoke and dust, and the dust removal effect is not obvious. It is not harmful to the harmful gases (such as fluorine-containing gases, sulfur dioxide, etc.) produced during gas combustion. did not exert any effective suppression or reduction effect
