Valve and tank combined slag inputting method

Abstract

The invention provides a material inputting method, and concretely relates to a method for inputting slag to a high-temperature slag processing device. The method utilizes the high-pressure sealing capability of a valve and the high-temperature slag containing capability of a slag containing tank, adopts the cooperation regime of a valve switch and a tank dumping process, and adopts an alternate work regime of the above two slag processing tanks to realize slag entrance and the continuous work requirements of a system. The method solves a problem that the slag inlet of the slag processing device is difficult to seal, realizes the closed feeding of the metallurgic slag to the slag processing device, and satisfies the high-pressure closed work requirement of the slag processing process of the slag processing device.

Description

technical field [0001] The invention relates to a material input method, in particular to a method for inputting molten slag to a high-temperature molten slag processing device in the technical field of high-temperature molten slag recovery. Background technique [0002] We know that the temperature of steel slag and blast furnace slag is 1400-1650°C, while the melting temperature of pure iron is 1538°C, which means that the temperature of the transported material slag may be higher than the melting temperature of iron, and the problem of blast furnace slag transportation is not only slag The problem of high temperature is mainly the condensation of slag. Therefore, the common material conveying forms of rotary sealing valve type in the market, as well as the material conveying forms of valve type, series and parallel tank type, and large and small bells are difficult to meet the requirements of the new slag processing device. The task of airtightly transporting high-tempera...

[0002] We know that the temperature of steel slag and blast furnace slag is 1400-1650°C, while the melting temperature of pure iron is 1538°C, which means that the temperature of the transported material slag may be higher than the melting temperature of iron, and the problem of blast furnace slag transportation is not only slag The problem of high temperature is mainly the condensation of slag. Therefore, the common material conveying forms of rotary sealing valve type in the market, as well as the material conveying forms of valve type, series and parallel tank type, and large and small bells are difficult to meet the requirements of the new slag processing device. The task of airtightly conveying high-temperature slag and granular slag from low pressure to high pressure, and from high pressure to low pressure

[0003] The existing slag treatment methods such as Inba method, Minte method, Jiaheng method, foam slag method and stuffy slag method do not require closed input and output of slag in the process, so the existing slag treatment devices and methods do not have similar Conveying method and device, the new valve tank combined slag conveying method is mainly a special method designed for the import and export of slag in the patented device of "Steam Circulation Blast Furnace Slag Heat Energy Utilization and Slag Treatment Implementation Device" with application number 200810229364
