Embodiment 1

[0050] The method for using the oxygen-enriched side-blown volatilization pool smelting to produce crude antimony trioxide device in this embodiment includes the following steps:

[0051] (1) The antimony-containing materials, anthracite, iron ore, and lime are measured according to the mass ratio of 100:17:22:10 from each silo 1 through the corresponding metering belt 2, and then transported to the furnace by the transfer belt 3 The electronic belt scale 4 on the top and the electronic belt scale 4 measure the total weight of the furnace materials, and then put them into the oxygen-enriched side-blown volatilization melting pool melting furnace through the feeding port 5. The area of ​​the oxygen-enriching side-blowing volatilization melting pool melting furnace is 2.16m 2 (1.2×1.8m), the materials entering the furnace undergo melting, dissociation, desulfurization, oxidation, volatilization and slagging reactions in the furnace. During the melting and reaction process, 75% (...

Abstract

A device for producing crude antimonous oxide through an oxygen-enriched side-blown volatilization melting bath in a smelting mode comprises stock bins, measurement belts, a transfer belt, an electronic belt scale, an oxygen-enriched side-blown volatilization melting bath smelting furnace, a vertical uptake flue, an electric dust collector and a bag dust collector. The oxygen-enriched side-blown volatilization melting bath smelting furnace comprises a furnace body which is defined by a copper water jacket and a molten steel jacket. Oxygen-enriched air spray guns are horizontally arranged on the two sides of the copper water jacket on the lower portion of the furnace body, and the muzzles of the spray guns are flush with the inner wall of the water jacket. Secondary air nozzles are arranged on the molten steel jacket on the upper portion of the furnace body. A hearth constructed with refractory bricks is arranged under the furnace body. An antimony matte siphon chamber is arranged on the front portion of the hearth. A slag siphon chamber is arranged on the back of the hearth. A feeding inlet is formed in the top end of the furnace body. The top end of the furnace body is connected with the vertical uptake flue. A waste heat boiler is arranged in the vertical uptake flue connected with the electric dust collector. The electric dust collector is connected with the bag dust collector. The device is low in energy consumption for operation, and is clean, friendly to the environment and low in production cost when being used for producing the crude antimonous oxide.

Description

[0001] This application is a divisional application with an application date of April 28, 2014, an application number of 201410173492.4, and an invention titled "A method and device for producing crude antimony trioxide by smelting in an oxygen-enriched side-blown volatilization pool". technical field [0002] The invention relates to a device for producing crude antimony trioxide, in particular to a device for producing crude antimony trioxide by smelting in an oxygen-enriched side-blown volatilization molten pool. Background technique [0003] Antimony metallurgy is divided into pyrometallurgy and wet method. At present, the pyrometallurgical process in the production of antimony metallurgy has an absolute advantage, reaching more than 95%; and the technological process of "antimony concentrate blast furnace volatilization smelting-coarse antimony trioxide reverberatory furnace reduction smelting" It is the basic process of most antimony smelters in my country at present. ...
