A device for producing tar by the continuous carbonization of plant biomass is that a feeding carbonization tube and a material discharging carbonization tube are vertically arranged inside a carbonization bed; the surrounding of the feeding carbonization tube and the material discharging carbonization tube is a burning chamber; the insides of the feeding carbonization tube and the material discharging carbonization tube are respectively filled with a helical feeding packing auger and a material discharging packing auger which are driven by a gearing to ensure that the material is turned and fallen uniformly. The feeding opening of the feeding carbonization tube and the material discharging opening of the material discharging carbonization tube are arranged at the lower part of the carbonization bed. The feeding carbonization tube is communicated with the material discharging carbonization tube by a material reversing tube arranged at the upper part of the carbonization bed. The top of the carbonization bed is respectively provided with vent-pipes which are communicated with the feeding carbonization tube and the material discharging carbonization tube, and the vent-pipes are communicated with a gas collecting tube. One end of a condenser is communicated with the gas collecting tube and the other end is communicated with a gas returning tube which is communicated with a burning device. The present invention uses the continuous carbonization of the plant biomass to produce the bar and ensures that the material is carbonized completely and uniformly, which not only can save energy but also can reduce the pollution to the environment.
Description
technical field [0001] The invention relates to equipment for producing tar by dry distillation, in particular to an equipment for producing tar by continuous dry distillation of plant biomass. Background technique [0002] The use of plant biomass to produce tar mostly produces gasified mixed gas through a closed carbonization still, or a fixed-bed gasifier, or a fluidized-bed gasifier, cools the mixed gas through a cooler, and uses a separator to separate the tar and wood vinegar. The liquid is separated to extract the tar. During the extraction process of tar, by-products are produced simultaneously: solid charcoal, wood vinegar and gasification gas. [0003] It is not easy to realize the continuous dry distillation of plant biomass by using a retort, or a fixed-bed gasifier, or a fluidized-bed gasifier, and the tar yield is relatively low. [0004] In the current carbonization furnace, there are carbonization tubes installed in parallel up and down and horizontally in ...
