Embodiment Construction

[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0027] Please refer to Figure 1 ~ Figure 2 , a multi-purpose biomass fixed-bed gasifier grate includes a horizontal movement mechanism, a vertical movement mechanism, a grate component and a reset mechanism; the grate component includes an upper grate 3 and a lower grate 6, and the upper grate The grate 3 is fixedly connected with the inner tube 2 of the gasifier, the lower grate 6 is arranged directly below the upper grate 3, and the vertical gap between the upper and lower grates is 3mm, which not only allows gas to pass through, but also blocks materials falling; the reset mechanism and the horizontal movement mechanism are respectively located at the two ends of the lower grate 6, the vertical movement mechanis...

Abstract

The invention discloses a multi-purpose biomass static bed gasifier grate. The multi-purpose biomass static bed gasifier grate comprises a horizontal moving mechanism, a vertical moving mechanism, a grid component and a reset mechanism; the grid component comprises an upper layer of grid and a lower layer of grid, the upper layer of grid is fixedly connected with the inner cylinder of a gasifier,and the lower layer of grid is located rightly below the upper layer of grid; the reset mechanism and the horizontal moving mechanism are oppositely arranged on the two sides of the lower layer of grid, the vertical moving mechanism is arranged below the lower layer of the grid, the horizontal moving mechanism and the reset mechanism can drive the lower layer of grid to conduct left and right reciprocating movement, and the vertical moving mechanism can drive the lower layer of grid to move up and down. The multi-purpose biomass static bed gasifier grate has the advantages that ash is loosenedand smashed through horizontal reciprocating movement of the lower layer of grid, an ash falling channel is formed through vertical movement of the lower layer of grid, so that the grate is applicable to various kinds of biomass raw materials, and the using cost is reduced.

Description

technical field [0001] The invention belongs to the field of biomass gasification equipment, and relates to a multipurpose biomass fixed-bed gasification furnace grate. Background technique [0002] my country's biomass resources are very rich, mainly in the form of plant resources including crops. Making full use of crop straw is of great significance for increasing farmers' income and reducing environmental pollution. The development of biomass carbonization, gasification and liquefaction technology has been paid more and more attention by enterprises and governments. [0003] Industrial biomass fixed bed gasifier grate is a key component of the gasifier, which plays a very important role in the normal production of the gasifier. The grate is a support for biomass raw materials, a channel for air and biomass gas, and a discharge channel for carbon and ash remaining after biomass gasification. At present, the gasifier grate is designed for a certain kind of biomass gasif...
