Problems solved by technology

In actual production, due to the limitations of production equipment and operating conditions, it is difficult for people to conduct field experiments on the roasting process of iron ore pellets
For example, in the roasting process in the rotary kiln, it is difficult to directly obtain the thermal data of the roasting process, and can only be derived and estimated from peripheral data

Abstract

The invention relates to an experimental method and a device for an iron ore pellet roasting process, belonging to the field of iron manufacture production. In order to research the iron ore pellet roasting process in terms of heat transfer, mass transfer, a roasting process mechanism, and the like, the invention discloses the experimental method and the device, wherein the device comprises a gastank, a draft blower, a combustion chamber, a roasting chamber, a smoke exhaust hood, an electronic balance, a PLC system, an industrial computer, a roasting cup, an electromagnetic disconnecting valve, an electrically operated valve, a manual control valve, a pressure gauge, a flow meter, a thermometer, a gas pipeline, an air pipeline, a combustion chamber high-temperature thermocouple, a roasting chamber high-temperature thermocouple, an annular pressure meter, a burner nozzle subassembly, a secondary air annular nozzle, a smoke gas collection hole, a smoke exhaust pipeline, an exhaust blower, a suspension fork, and the like. The device generates smoke gas with different flow speeds, different temperatures and different gases to roast a pellet material layer in a flow-through way, measures and collects relative data, especially the inner temperature distribution of the pellet material layer, and provides important experiment evidence for the theoretical research and the actual production of the pellet roasting mechanism.

Description

An experimental device for iron ore pellet roasting process technical field The invention belongs to the field of ironmaking production. In particular, the invention relates to an experimental device and method for heat and mass transfer and roasting mechanism research of iron ore oxidation pellet roasting process. Background technique In actual production, due to the limitations of production equipment and operating conditions, it is difficult for people to conduct field experiments on the roasting process of iron ore pellets. For example, in the roasting process in the rotary kiln, it is difficult to directly obtain the thermal data of the roasting process, and can only be derived and estimated from peripheral data. The iron ore pellet roasting process includes a series of complex physical and chemical processes such as heat and mass transfer of porous media, gas-solid two-phase flow, and phase transition, involving engineering thermophysics, fluid mechanics, metallurgi...
