Calcining furnace tail gas purification treatment device and process

Abstract

The invention discloses a calcining furnace tail gas purification treatment device and process, the calcining furnace tail gas purification treatment device comprises a calcining furnace, a boiler, a heat exchanger, an air blower and purification equipment, the purification equipment comprises a purification tank, a dust removal component and a purification component are arranged in the purification tank, and the dust removal component comprises multiple sets of dust removal cylinders and spiral blades. According to the calcining furnace tail gas purification treatment device and process, dust residues in waste gas are isolated and discharged to the dust collection box through rotation of the spiral blades and the filter cloth, the gas is upwards discharged through the filter cloth and enters the purification barrel through the dust removal exhaust pipe, and liquid in the alkaline water tank is pumped through the water pump and sprayed through the atomization spray head; the waste gas entering the purification cylinder is in contact with vaporific alkali liquor to neutralize sulfide and alkaline water, so that the waste gas is purified, foreign gas in organisms is effectively removed, the waste gas purification quality is better improved, and the influence of the waste gas on the surrounding environment is reduced.

Description

technical field [0001] The invention relates to the technical field of tail gas purification, in particular to a calciner tail gas purification treatment device and process. Background technique [0002] Calciner is a common high-temperature treatment equipment that uses natural gas, oil or electricity as energy sources for ironmaking, recovery of rare metals, and production of special chemicals. It is widely used in metallurgy, steel, and chemical industries. During the calcination process, a large amount of 400°C high-temperature tail gas is produced, and the tail gas contains a large amount of harmful components. [0003] As energy saving and environmental protection are getting more and more attention, it is necessary to develop a calciner tail gas purification treatment process, which can effectively purify and treat this part of high-temperature calciner tail gas so that it can meet the emission standards. Usually, the treatment scheme of dust removal equipment combin...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a calciner tail gas purification treatment device and process, which solves the problem that the existing purification treatment equipment is set independently of each other, has a large volume, occupies a large site, and consumes less steel for manufacturing and installation. High, high investment costs, high operating costs, inconvenient centralized management, not applicable to small-scale domestic calciner tail gas treatment stations
