Problems solved by technology

[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 The conveying method and device, the new valve-tank combined water slag output method device is mainly a special method device designed for the slag export of the patented device of "Steam Circulation Blast Furnace Slag Heat Energy Utilization and Slag Treatment Implementation Device" with application number 200810229364

Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing:

[0023] figure 1 The working process of merging tanks is as follows:

[0024] Before slag discharge: the tank 1 of the slag treatment device is sealed, the slag treatment device has been working and produces a certain amount of water slag or dry slag, and the valves 2 and 5 of the tank 3 are in the closed position.

[0025] Slag discharge: tank a#, open the slag discharge valve 2a, the slag flows into the tank 3a, close the slag discharge valve 2a after the tank is full of slag, open the drain pipe valve 4a or the pressure relief pipe valve 6a to discharge water or release pressure, wait for water, gas After the release, close the valve 4a or 6a, open the slag discharge valve 5a to discharge the slag, close the slag discharge valve 5a after the slag is discharged, open the pressure charging pipe 6a to pressurize the tank 3, and close the pressure after the pressure of the t...

Abstract

The invention provides a method and a device for outputting metallurgical slags from an enclosed slag treating device, and more specifically relates to a method for outputting grain slags or dry slags form the enclosed slag treating device. Slags and water separation is implemented in a grain slag outputting process. Concretely, the method, by using a valve-pot combining manner, a series-parallel structure, an alternative work system, and compressing and decompressing processes, satisfies requirements that a water volume will not appear big change, or pressure of steam and air will not appear big fluctuation in the pot of the slag treating device in the slag outputting process. The method solves a problem for enclosed discharging of a slag outlet of the new slag treating device, implements slag and water separation in the slag outputting process, and is a novel slag and grain slag outputting method.

Description

technical field [0001] The invention relates to a method and device for outputting metallurgical slag from a closed slag treatment device, in particular to a method for outputting water slag or dry slag from a closed slag treatment device, and realizes slag-water separation during the water slag output process . Background technique [0002] The new slag treatment method and device require the slag treatment process to be completely carried out in a closed container, so the slag produced in the closed container during the slag treatment process has the problem of airtight output. According to production needs, the slag output is sometimes water slag, sometimes It is high-temperature dry slag, and the tank in the slag treatment process is generally operated at high pressure. During the high-pressure operation, the slag output is realized. During the output process, the slag-water separation and steam-slag separation are realized. During the slag discharge process, it is not a...
