Abstract

The invention discloses a fixed bed slag vapourizing furnace distributing device. The fixed bed slag vapourizing furnace distributing device comprises a material canister and a material-guiding part,the material canister is arranged below a charging adapter at top of a vapourizing furnace, the material-guiding part is fixed in a lower end of the material canister through a material-guiding fixedmechanism, the material-guiding part comprises a conical top cap and a material distribution cone arranged below the conical top cap, and pores are uniformly arranged at the conical top cap and the material distribution cone. According to the invention, a mechanical driving apparatus and a rotation part are not provided, furnace overhaul due to fault of the rotation part can be avoided, a stable operation period of a vapourizing furnace is increased, the unkeep maintenance cost of the vapourizing furnace is reduced, and the cost consumption due to gas from bump fragmentation by stirring the solid raw materials is reduced.

Description

technical field [0001] The invention relates to a distributor of a gasification furnace, in particular to a distributor of a fixed bed slag gasification furnace. Background technique [0002] In the existing fixed-bed gasifier, the solid raw material is usually various high-quality coal, low-quality coal, inferior coal, peat, solid waste and solid carbon-containing biomass with a particle size of 5 to 100 mm. The upper part of the furnace is added, and it moves naturally from top to bottom under its own gravity. During the moving process, it exchanges heat with the rising gas and the temperature rises gradually, and finally completes a series of gasification reactions. [0003] The existing fixed-bed pressurized gasification technology adopts the method of distributing solid raw materials into gasification, which usually installs mechanically driven rotating parts in the gasifier for distribution. This method of distribution has the advantage of relatively uniform distributi...
