Embodiment Construction

[0017] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0018] see Figure 1 ~ Figure 3 , a biomass-derived fuel gasification test device, comprising an electric control box 19 and a fluidized bed gasifier 15, the fluidized bed gasifier 15 is sequentially provided with a heating sleeve 16, a refractory concrete layer 14 and insulation layer 13, and a wind chamber 2 is provided at the bottom of the fluidized bed gasification furnace 15. In this embodiment, an air distribution plate 3 is arranged on the top of the air chamber 2, so that the air flow can evenly enter the fluidized bed gasification furnace. The concrete forming the refractory concrete layer 14 uses cement aluminum sulfate cement as the cementitious material.

[0019] The fluidized bed gasifier 15 is connected with a feeding mechanis...

Abstract

The invention discloses a gasification experimental device of biomass derived fuel. The gasification experimental device comprises an electronic control box and a fluidized bed gasification furnace, wherein a heating sleeve, a fire resistance concrete layer and a heat insulating layer are sequentially arranged in the fluidized bed gasification furnace from inside to outside; an air chamber is arranged at the bottom of the fluidized bed gasification furnace; a feeding mechanism, an exhaust airflow processing mechanism and a blasting mechanism are connected to the fluidized bed gasification furnace; a screw feeder which is horizontally arranged is adopted by the feeding mechanism; a sleeve and a screw rod which is mounted in the sleeve are arranged in the screw feeder; the screw rod is provided with a central shaft and helical blades; a feed opening is formed in the sleeve; a feeding hopper is fixedly connected to the feed opening; a U-shaped frame is fixedly connected to a position, opposite to the feed opening, on the central shaft; the U-shaped frame is horizontally arranged; two side arms of the U-shaped frame are parallel to the helical blades; rollers are mounted at the bottom of the U-shaped frame in a sleeving manner. According to the gasification experimental device of the biomass derived fuel disclosed by the invention, feeding continuity and feeding homogeneity can be improved, and the safety of the device can be improved.

Description

technical field [0001] The invention relates to a test device, in particular to a biomass derived fuel gasification test device. Background technique [0002] With the sharp increase of energy consumption and the improvement of people's awareness of environmental protection, a worldwide energy crisis has been triggered. Biomass is favored by countries all over the world because of its easy acquisition and short regeneration cycle, and occupies an important seat in renewable energy. At the same time, biomass can not only be used as renewable energy, but also can realize the harmless reuse of organic waste such as agriculture and forestry. developed rapidly. [0003] At present, the conversion forms of biomass mainly include biomass gasification, liquefaction, solidification and direct combustion. Among them, biomass gasification is one of the important conversion forms. The furnace types used in gasification mainly include fixed bed and fluidized bed. Among them, the str...
