Embodiment 1
[0027] see figure 1 , the comprehensive utilization process of biomass rotary dry distillation, including the following process steps:
[0028] a. Prepare materials. Firstly, select biomass solid raw materials without mildew and deterioration. The selected biomass solid raw material wood chips have a water content of 17%, a length of ≤65 mm, and a rated output. The rotation speed of the retort is set at 4 rpm;
[0029] b. Air heating, transportation and recycling. Start the blower, ignite the heating furnace, and send the hot air heated to about 650° through the high-temperature air supply air box, the tail air box of the retort machine, the hot air pipe inside the retort machine, the air collector box of the retort head, and the low-temperature air exhaust box into the first stage. After the first heat exchanger flows into the heating furnace, the blower of the second heat exchanger is started at the same time to provide high-temperature oxygen for the diesel burner; after t...

Abstract
The invention provides a biomass rotating and destructive distillation type comprehensive utilization process. The process comprises the following steps: a, preparing materials; b, heating air, conveying and circulating; c, conveying raw materials; d, performing biomass destructive distillation; e, performing tar cracking; f, cooling biomass gas, purifying and applying; and j, cooling biomass charcoal, metering and packing. The process has the advantages and effects that 1, a large amount of biomass gas can be continuously produced, and mass industrial production can be carried out; 2, the self-generating substance gas is burnt to be used as a heat source after the process is performed, so that the energy can be saved, and the environment can be protected; 3, the self-generating substance gas is treated by tar cracking to be heated, which can remove the impurities and improve the purity, concentration and calorific value of biomass gas; 4, throttling valves in each pipeline, feeding, carbon discharging, slag discharging and an air blower in the process are automatically controlled, so that the production efficiency can be greatly increased.
Description
technical field [0001] The invention relates to a biomass dry distillation process, in particular to a biomass rotary dry distillation comprehensive utilization process. Background technique [0002] At present, my country's biomass gasification technology (using air as the gasification agent) ranks among the best in the world, but the market shrinks due to the high tar content and low calorific value of the gas. Biomass dry distillation technology has attracted great attention from biomass energy research and development units because of its high calorific value and pure gas gas quality. They use inner and outer cylinder jacketed reactors for dry distillation of biomass solid fuel, and the biomass gas obtained from dry distillation is used for centralized Gas supply, the production scale is small. The process route is to feed materials from the top of the reactor and discharge charcoal from the bottom. The biomass solid fuel is heated by the diversion of the fire channel. ...
