Abstract

The invention discloses a small-flow pneumatic feeder for feeding a gasification furnace. An inlet of the feeder is located in the side face of the upper portion of the feeder, a motor is installed above the top end of the feeder, and an output shaft of the motor is connected with stirring blades; carrier gas enters an upper section feeding pipe and a lower section feeding pipe through a carrier gas inlet and the upper section feeding pipe is directly communicated with an inner cavity of the feeder; the lower section feeding pipe penetrates through the inner cavity of the feeder, an outlet of the lower section feeding pipe serves as a carrier gas outlet, and a small feeding hole through which boiling solid particles enter the pipe is formed in the portion, located in the inner cavity of the feeder, of the lower section feeding pipe. The small-flow pneumatic feeder is suitable for conveying and feeding the large-grain particles, the particles are fed evenly, small and accurately, the flow is continuous and stable, and the micro-feeding requirement of the gasification furnace can be met.

Description

technical field [0001] The invention relates to a pneumatic feeder, in particular to a small-flow pneumatic feeder used for feeding gasification furnaces, which is suitable for the transportation and precise feeding of particles with larger particle diameters. Background technique [0002] The feeding method of gasifier is generally divided into screw feeding method and pneumatic feeding method. The screw feeding method is not suitable for small-scale material transportation in the laboratory due to the large amount of feeding, uneven feeding, instability and easy blockage. The pneumatic feeding method can make the particles and the carrier gas form a suitable flow state, which is convenient for pneumatic transportation. However, at present, the pneumatic feeding method is mostly used in the pressurized feeding of large (industrial) gasifiers, and is suitable for biomass. Small flow pneumatic feeding devices with large particles, less feeding, accurate feeding, and continuo...
