High-temperature smoke purifier

Abstract

The invention discloses a high temperature flue gas purification device used for the metallurgy and building materials industries and provides a high temperature flue gas purification device which has the advantages of better purification effect, low concentration of the gas emission and reduction of the energy consumption; the device includes a high temperature flue gas generation device, a draft fan and an exhaust funnel which are connected by pipelines in series; the high temperature dust collector is connected with the high temperature flue gas generation device and the draft fan by the pipelines; as the cooling device is omitted, the device has the advantages of small occupy area and small maintenance, does not need dust blocking and cleaning work for the cooling device, reduces the operation points for unloading dust, reduces the energy consumption of the system, does not has cooling consumption, has low total pressure of the main system fan and reduces the motor power; As the high temperature flue gas is purified in the high temperature region directly, and then interfused into the atmosphere, the high temperature flue gas purification device can reduce the temperature rapidly and cuts down the temperature section in which the dioxin is generated.

Description

technical field [0001] The invention relates to a high-temperature flue gas purification device in metallurgy and building materials industries. Background technique [0002] In the prior art, the purification device for high-temperature flue gas consists of high-temperature flue gas generating equipment, cooling facilities, dust collectors, induced draft fans, and exhaust cylinders connected in sequence through pipelines. Since the device is equipped with cooling facilities, the pipeline configuration of the device Long, the equipment covers a large area, and the equipment investment cost is high; because the cooling facility is installed in front of the dust collector, the flue gas entering the cooling facility contains dust, causing the cooling facility to be often blocked and requires frequent maintenance; the cooling facility requires additional energy; the resistance of the entire device High, between 4500-7100Pa, the main fan consumes a lot of energy.
