Abstract

The invention relates to a pressure vessel, in particular to a steam-generating pressure reactor. The problem of recovery of heat carried by steel slag and iron slag in the smelting process of steel and iron is solved. The steam-generating pressure reactor structurally comprises a reactor body, a reactor body internal heat-preservation layer, a reactor cover, a reactor cover heat-insulation and heat-preservation layer, a spraying system and a locking device. A using method comprises the steps that steel slag and iron slag are received through a slag tank, and transported and hoisted into the pressure reactor, then water is sprayed, thus stem is generated and enters a heat-storage and pressure-stabilizing device, and finally, the hot steam passes through an adjusting valve and enters a steam turbine in the stable flow pressure for power generation. The heat carried by the steel slag and the iron slag can be reutilized effectively.

Description

technical field [0001] The invention relates to a pressure vessel, in particular to a steam generating pressure kettle. Background technique [0002] The status quo of my country's iron and steel smelting: my country is a major producer of iron and steel, and its crude steel output ranks first in the world all year round. In 2014, my country's crude steel output reached 823 million tons, accounting for about 49.5% of the world's crude steel output. Although since 2016, my country's iron and steel industry has accelerated its capacity reduction, the output has remained at around 800 million tons. [0003] The main process of iron and steel smelting: Mining --- Mineral processing (crushing iron ore and magnetically separating it into iron concentrate powder) --- Sintering (Sintering iron concentrate powder into sintered ore with a certain strength and particle size) --- Smelting (transport the sinter to the blast furnace, hot air and coke reduce the sinter to molten iron...pi...
