Further, longitudinally it is welded with the fin of augmentation of heat transfer at described heating tube bundle outer wall, is arranged over safe diffusion device at described water-jacket typ cyclone dust extractor, described rear smoke box sidewall is provided with bellow expansion device.
Further, at described gas combustion chamber rear portion, front smoke box top, rear smoke box top, conveying worm import department is provided with temperature instrumentation interface.
Further, it is provided with manometer interface at described charging burner middle side part, stove tail apparatus top.
Further, the gas outlet tube side at described cyclone dust extractor configures the interface of fuel gas in-line analyzer, is provided with steam pipe interface and manometer interface on described air curtain damping mechanically-sealing apparatus top.
This biomass dry distillation gas production rotary furnace has the following advantages that and effect:
1, biomass dry distillation gas production rotary furnace of the present invention achieves and biomass carries out continuous scale carbonization, produces combustion gas and carbonization product.Compared with batch (-type) dry distilling stove, effects of energy saving and emission reduction is obvious, has purified environment and labor strength, promotes the operability of distillation process process, provides technical support for automated production.
2, the present invention solves revolution body of heater and the sealing problem of static burner of major diameter, prevent dry distilling gas leakage, optimize and devise end face air curtain damping mechanically-sealing apparatus, it is this novel serialization that is achieved, the key problem in technology of large-scale production.
3, for avoiding dry distilling combustion gas to carry the phenomenon of dust blocking outlet conduit, being configured with water-jacket typ cyclone dust extractor inside stove tail apparatus, this is the technical guarantee of longtime running of the present invention.
4, at the biomass carbon discharge pit of stove tail apparatus, it is provided with heat recovery heat exchanger, makes charcoal forced cooling to be come out of the stove, oxidation occur with the oxygen in air after preventing it from coming out of the stove or even burns mistake, thus improving quality and the grade of biomass carbon.
5, the design of the body of heater rotary motion mechanism of the present invention, change traditional gear transmission mode, use pin tooth driving device, adapt in the open under environment, heavy load, the drive technology requirement of the big radius of gyration, be not only greatly reduced the manufacturing cost of drive mechanism, also solves jumbo and installs, debugging and maintenance difficulty, have good economy.
6, in order to compensate after body of heater and heating tube bundle be heated, the stress problem produced because of line non-homogeneous expansion weighing apparatus, the present invention is provided with bellow expansion device at rear smoke box, decreases equipment failure rate, extension device service life.
