Abstract

The present invention discloses a device for transportation of powder, comprising: a mixing pipe having one end connected to a venturi; a gas supply nozzle disposed inside the mixing pipe; a feed pipe connected to the mixing pipe and on the gas supply nozzle, wherein an angle between 0 and 90 degrees but not including 0 or 90 degrees is arranged between the feed tube and the mixing tube.

Description

technical field [0001] The invention relates to a powder conveying device, especially a powder conveying device capable of conveying high-temperature powder. Background technique [0002] At present, calcium loop capture of carbon dioxide has become a carbon reduction technology, which uses CaO to absorb CO2 in flue gas to react to generate CaCO3, thereby reducing the concentration of CO2 in flue gas. After CaCO3 is calcined in a calciner, CaO and CO2 can be separated, and the temperature of CaO powder is about 650-750°C. The CaO powder usually needs to be sent to the 25-meter-high feed bin through a pneumatic conveyor (Pneumatic Conveyer) to carry out the cycle operation of carbon capture. It must still be maintained above 400°C for easy operation. [0003] However, most of the existing powder conveying devices can only convey powder at room temperature, and cannot cope with high-temperature powder. In addition, the structure of the existing powder conveying device is th...
