Abstract
The utility model relates to a gasification furnace for biomass fine granule material, which is composed of a feeding device, a gasification furnace body and an insulating jacket. The gasification furnace body is arranged in the insulating jacket, and the feeding device is connected with the lower part of the gasification furnace body. The feeding device is composed of a screw conveyer and a bucket, and the bucket is arranged on the feeding inlet of the screw conveyer. The utility model is characterized in that a toggling device is arranged above the feeding inlet of the screw conveyer. Because the utility model is provided with a toggling device above the feeding inlet of the screw conveyer, biomass fine particle materials can continuously fall into a screw conveying pipe under the toggling action of the toggling device, so that the materials in the bucket can not bridge or scaffold, accordingly, the stable continuous feeding can be realized, and the stable continuous feeding is good for the utility model to operate normally.
Description
Technical field
The utility model relates to biomass fine granular materials gasification system feeder, relates in particular to a kind of biomass fine granular materials vapourizing furnace that is used for the fluidization vapourizing furnace.
Background technology
The type of furnace that present domestic gasifying biomass adopts mainly contains downdraft fixed-bed gasification furnace and fluidization vapourizing furnace.Downdraft furnace mainly is applicable to the gasification of hard stalk raw material, and the throughput of this type of furnace is less, can't satisfy the demand of extensive gasification.The fluidization vapourizing furnace then can be fit to the fine particle biomass material, and can realize extensive gasifying biomass production.
In biomass fine granular materials gasification technology, the fluidization gasified boiler system must guarantee raw material continous-stable add and keep good system sealing, to realize the normal operation of gasifying biomass.The fluidization vapourizing furnace adopts the feed way of spiral conveyer usually, because biomass fine granular materials such as wood chip, crop stalk are pulverized material, more open, accumulation severe is little, fiber is elongated, can produce the scaffold arch formation in hopper, influences the continuous conveying of material, stopping property between fluidization vapourizing furnace and hopper is very poor, and gasification installation can not normally be moved continuously and stably.When system adopts negative-pressure operation, can cause that gasifying medium enters the fluidization vapourizing furnace in spiral conveyer, labile factors such as the channel of generation fluidized-bed, bias current cause the gasification of fluidization vapourizing furnace normally to move; When system adopted positive pressure operation, the fluidization furnace gas was overflowed from spiral conveyer, makes material be difficult to enter in the fluidized bed furnace, also usually can cause material burning in the hopper, even the meeting presence of fire, influenced the normal operation of fluidization vapourizing furnace.Therefore, fluidization vapourizing furnace in the past, because bridge formation, scaffold and cannot realize continuously to biomass fine granular materials (particle size≤8mm) stably reinforced usually as the pulverizing material of agricultural crop straw, make that the fluidization vapourizing furnace is that the application of the gasification technology of raw material is restricted at agricultural crop straw, even can't use.
Summary of the invention
The utility model provides a kind of biomass fine granular materials vapourizing furnace that helps normal operation and can realize continuous charging.
The utility model adopts following technical scheme:
A kind of biomass fine granular materials vapourizing furnace that is used for gasifying biomass, form by feeder 6, vapourizing furnace body 1 and insulation jacket 2, vapourizing furnace body 1 is located in the insulation jacket 2, feeder 6 is connected with the bottom of vapourizing furnace body 1, feeder 6 is made up of spiral conveyer 61 and hopper 62, hopper 62 is located on the opening for feed of spiral conveyer 61, it is characterized in that being provided with above the opening for feed of spiral conveyer 61 setting gauge 63.
Compared with prior art, the utlity model has following advantage:
(1) because the utility model is provided with setting gauge above the opening for feed of spiral conveyer, by the toggle action of setting gauge to the biomass fine granular materials, material then can constantly fall in the spiral conveying tube, material in the hopper can not be built bridge or scaffold, realize the reinforced of steady and continuous, helped normal operation of the present utility model.
(2) in the discharging transition conduit that is upturned, the deadweight of material can make material fall after rise downwards, and the pushing effect of spiral conveyer, material is upwards advanced along the discharging transition conduit, thereby make material be full of the discharging transition conduit, pack density is wherein increased greatly, but continuously charging, cause fluidization vapourizing furnace and feeder to be closed isolation, more effectively guaranteed the overall tightness of fluidization vapourizing furnace, avoid the loss or the furnace gas effusion of fluidization vapourizing furnace furnace pressure and caused danger, more helped the normal operation of biomass gasifying furnace.
