Embodiment Construction

[0033] Now in conjunction with accompanying drawing, the present invention is described in further detail.

[0034] like figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 and Image 6 The compound air extraction device for the reaction of manganese ore powder and sulfuric acid includes a compound tank 1 and an induced draft fan A. The compound tank 1 is provided with a stirring system 2. The compound tank 1 is connected to the induced draft fan A through the exhaust pipe 4, and the induced draft fan A is connected tangentially. After the swirl tower 7 is emptied, the air intake pipe 4 is provided with a damper 3; the induced draft fan includes a fan impeller 41 and a casing 45, and the fan impeller 41 includes an impeller back plate 37, an impeller panel 38 and a blade 31, and the blade 31 is arranged as The impeller shaft is radially and centrally symmetrical in a hollow anti-drop shape, and the impeller back plate 37 is dish-shaped; the hollow anti-drop-shaped bla...

Abstract

The invention discloses a combination exhausting device for manganese ore powder and sulfuric acid reaction. Stirring systems are arranged in combination barrels, the combination barrels are connected with a draught fan through exhaust pipes, the draught fan is tangentially connected with a swirl tower and then is exhausted, and air valves are arranged in the exhaust pipes; multiple groups of swirlers, which consist of large swirl plates, small swirl plates and conical hopper plates, are vertically arranged in the swirl tower; an impeller of the draught fan has hollow and inverted-droplet-shaped vanes; and the appearance contour line of the draught fan is involute. According to the combination exhausting device, the real-time exhaust of carbon dioxide gas produced from the reaction between the manganese ore powder and the sulfuric acid is realized through the draught fan and the swirlers, the proceeding of the reaction is facilitated, carrying powdered ore is effectively recovered through gas swirling, and energy saving and emission reduction are realized; and the vanes are of hollow and inverted-droplet-shaped structures, thus dust on the impeller of the draught fan can be cleaned in real time, the strength of the impeller of the fan is improved, the stability is enhanced, and safety accidents caused by dust accumulation are effectively avoided, so that the application prospect is broad.

Description

technical field [0001] The invention relates to a combined air extraction device, in particular to a combined air extraction device for reacting manganese ore powder that does not accumulate dust in a fan and 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 waste an...
