The invention relates to the technical field of
flue gas purification and particularly relates to a device
system applicable to a
flue gas and
powder material mixed reaction. The device
system applicable to the
flue gas and
powder material mixed reaction comprises a reactor, wherein a
powder material inlet is formed in the top of the reactor, a powder material outlet is formed in the bottom of the reactor, a jacket sleeves the external wall of the reactor, a gas flow chamber which is used for circulating flue gases is arranged between the internal wall of the jacket and the external wall of the reactor, the
internal cavity of the reactor communicates with the gas flow chamber through a bottom opening, a
flue gas inlet is formed in the upper part of the sidewall of the reactor, and a
flue gas outlet is formed in the upper part of the sidewall of the jacket; and a bottom opening of the jacket is downwards connected with a blanking pipeline, an adsorption chamber with a Venturi tube is arranged below the blanking pipeline, a gas inlet of the Venturi tube is connected with an external
gas supply pipeline, and a gas outlet of the Venturi tube communicates with a material conveying pipeline. By adopting the technical scheme, the device
system has the advantages that the problem that a mechanical air lock is short in life, is prone to blockage and is prone to
rust corrosion after the mechanical air lock is corroded by
water vapor is avoided, and the storing quality and conveying effect are ensured by the bridge breaking effect of a
storage tank.
