Problems solved by technology

[0003] 1. Batch calcination kiln equipment cannot realize continuous industrial operation;
[0004] 2. The dry distillation gas of many equipment is recycled by natural ignition, which cannot be completely burned and cannot effectively control the emission of nitrogen oxides;
[0005] 3. The rotary retort equipment arranged in an inclined manner has a large size and a long rotary sealing surface. Most of them adopt the traditional labyrinth sealing structure, which has poor sealing performance and has safety and environmental protection problems of toxic retort gas leakage.

Abstract

The invention discloses a destructive distillation device of a biomass horizontal rotary drum, which comprises a feeding mechanism, a driving mechanism, a rotary drum mechanism, a discharging mechanism, a public chassis, a retorting gas combustion furnace, an air draft and an assistant part; the feeding mechanism comprises a feeding shell and an internal feeding screw; the rotary drum mechanism comprises an outer drum and an inner drum; by adopting the horizontal setting, the inner part of the inner drum is provided with an oblique turning plate for overturning and conveying materials along with the rotating process of the inner drum; the discharging mechanism comprises a discharging shell and an inner discharging screw; every rotating sealing place adopts an elastic mechanical contact type sealing structure pressed by a graphite disk through a metal expansion joint; the assistant part comprises a first starlike blocking valve and a second starlike blocking valve which are connected tothe feeding opening and the discharging opening. The destructive distillation device is stable in running, long in service life, big in processing amount and can continuously work; the material is uniformly heated and completely burned; the destructive distillation device is leakage-free, safe and reliable, green and environment-friendly.

Description

technical field [0001] The invention relates to the field of biomass pyrolysis equipment, in particular to a biomass horizontal drum dry distillation device. Background technique [0002] Dry distillation pyrolysis equipment uses biomass as raw material, and through dry distillation pyrolysis and carbonization, the carbon and hydrogen elements in the raw material are converted into mixed combustible dry distillation gases such as hydrogen, methane, and carbon monoxide, and charcoal and by-product tar are produced at the same time. There are many such retort pyrolysis equipment on the market, including the traditional batch calcining kiln method, as well as the inclined rotary retort equipment and spiral retort equipment developed in recent years. Although these equipment have played a certain role in the development and utilization of renewable energy , but it also has the following shortcomings or deficiencies: [0003] 1. Batch calcination kiln equipment cannot realize co...
