Abstract

The invention discloses a combination gas exhaust system for the manganese mineral powder and sulfuric acid reaction. The system is characterized in that stirring systems are arranged in combination barrels; the combination barrels are connected with an induced draft fan through gas exhaust pipes; the induced draft fan is tangentially connected with a cyclone tower for exhaust, and dampers are arranged in the gas exhaust pipes; multiple groups of cyclone devices are vertically arranged in the cyclone tower, and each cyclone device comprises a large cyclonic plate, a small cyclonic plate and a conical bucket plate; an impeller of the induced draft fan has a structure comprising hollow wedge-shaped blades and a dish-shaped back plate; the shape contour line of the induced draft fan is an involute line. By means of the induced draft fan and the cyclone devices, carbon dioxide gas produced in the manganese mineral powder and sulfuric acid reaction is exhausted in real time, the reaction is facilitated, carried mineral powder is effectively recovered through gas cyclone, and energy conservation and emission reduction are realized; according to the structure comprising the hollow wedge-shaped blades and the dish-shaped back plate, dust on the impeller of the induced draft fan is cleaned in real time, the strength of the impeller of the induced draft fan is increased, the stability is enhanced, the safety accidents caused by dust accumulation are effectively eliminated, and the application prospect is broad.

Description

technical field [0001] The invention relates to a combined air extraction system, in particular to a combined air extraction system in which manganese ore powder which does not accumulate dust in a fan reacts with sulfuric acid. Background technique [0002] Combining a certain amount of manganese ore powder with sulfuric acid is a necessary process step in the electrolytic manganese industry. The main reaction is the reaction between sulfuric acid and manganese carbonate to generate manganese sulfate and a large amount of gaseous carbon dioxide. Due to the large amount of carbon dioxide produced, in order to promote The reaction proceeds in the positive direction, usually requiring the design of a powerful exhaust system to discharge carbon dioxide. Since the exhaust system requires a particularly large amount of air, the air flow often contains a large amount of mineral powder dust. Therefore, in addition to the exhaust, the mineral powder needs to be recycled to avoid was...
