Powder iron charging device

Abstract

The invention discloses a powder iron charging device, comprising a delivering pipe, a reactor, and a gas separation device; the delivering pipe guides the gas-powder iron flow through the gas and delivers the powder iron mine to above the delivering pipe; the reactor enables the powder iron delivered by the delivering pipe to react with the reaction gas in order to produce the chemical reaction; the gas separation device is used for separating the powder iron and the delivering gas which are delivered by the delivery pipe and the load the powder iron into the reactor; and the gas used during the delivery is not charged into the reactor, but discharged after separation.

Description

technical field [0001] The present invention relates to a powder iron ore charging device for charging fine iron ore into a reactor by separating the fine iron ore conveyed by gas. More particularly, the present invention relates to a fine iron ore charging apparatus capable of realizing an efficient gas-fine iron ore separation system for separating fine iron ore conveyed with gas in a conveying pipe and then conveying it into a reactor. Background technique [0002] At present, there are many technologies for conveying the powder into the reactor after usually extracting it. The powder is extracted from the powder sample tube by screw type etc. and then directly transported to the reactor, or a certain amount is extracted from the powder sample tube and then transported to the reactor by transport gas. [0003] First of all, when using a screw (Screw) to directly extract powder from the reactor, the device required is a device that can transport the powder to a height muc...

Problems solved by technology

However, when the gas and fine iron ore transported through the transport pipe are directly charged into the reactor, the transport gas is mixed with the reaction gas in the reactor, and more fine iron ore is flying in the fluidized reactor
