Description

technical field [0001] The invention relates to solid fuel gasification equipment, in particular to a solid fuel spiral dry distillation machine. Background technique [0002] Biomass is recognized as the most potential renewable energy in the world, and the form of biogas and biomass gas is widely used to supply gas to individuals or communities. Although the effect of biogas is good, due to the limited scope, it is difficult for biomass gas to reach the standard with low calorific value and tar content and gradually withdraw from the market. Using biomass dry distillation technology to produce dry distillation technology, dry distillation gas, tar, biomass charcoal, and wood vinegar are widely used in various fields of the national economy, which not only improves the quality of biomass gas, but also makes by-products provide very important raw materials for the chemical industry. Researchers have successively developed vertical biomass distillation devices and horizontal...

AI Technical Summary

Problems solved by technology

On the basis of the traditional dry distillation reactor, the vertical biomass carbonization device creatively designs a rotary sealing device for feeding and carbon discharge. This device reduces energy consumption, but the fuel naturally hangs down in the carbonization cylinder, and the small diameter of the carbonization cylinder results in a large output. Underneath, the fuel with a large diameter of the retort cylinder is heated unevenly, and the fuel remains in the retort cylinder for a long time, which reduces the carbon production

[0003] Horizontal biomass retort device, the retort cylinder is inclined 3 to 5° relative to the horizontal foundation, multiple hot air pipes are designed parallel to the inner circumference of the retort cylinder, hot air boxes are designed at both ends of the retort cylinder, and the rack surrounding the retort cylinder is connected to the drive gear. Rotating under the action of the retort, the fuel is put in from the top of the outer cylinder of the retort screw auger, the retort screw auger passes through the hot air box and is inserted into the retort cylinder, the fuel is sprinkled in the middle of the hot air pipe and falls into the retort cylinder cavity, and the retort cylinder and the hot air box rotate Sealed connection, dry distillation into charcoal under the heat radiation of the hot air pipe, along the design slope of the dry distillation machine, falls into the charcoal discharge machine at the bottom of the hot air box at the other end of the dry distillation machine. When the shaft extends into the retort chamber, it is easy to break when encountering hot air, and during the thermochemical reaction of the fuel in the retort area, the amount of tar sticking to the hot air pipe increases with time, and the amount of mechanical maintenance required for equipment operation is large
