Straw pyrolysis and carbonization equipment is used for conveniently realizing pyrolysis and carbonization treatment on straws. The equipment comprises a hopper, a spiral conveyer, an inclined spiral,a heat exchanger, an oil-gas separator, a tube-in-tube condenser, a three-phase separator, a coil condenser and a pyrolysis gas combustor which are sequentially arranged according to the technological process, wherein an air seal machine is arranged between the hopper and the spiral conveyer, a plurality of heating furnaces which are sequentially arranged are arranged on the periphery of the spiral conveyer, the rear end of the spiral conveyer is communicated with the front end of the inclined spiral, and the rear end of the inclined spiral is communicated with a carbon collecting box; the rear end of the spiral conveyer is connected with the heating furnaces through pipelines; the heating furnaces are connected with the oil-gas separator through pipelines; the oil-gas separator is connected with the tube-in-tube condenser through a pipeline; the tube-in-tube condenser is connected with the three-phase separator through a pipeline; the three-phase separator is connected with the coilcondenser by a pipeline; the coil condenser is connected with the pyrolysis gas combustor by a pipeline; a filter screen is arranged between the pipeline connected with the heat exchanger and the rearend of the spiral conveyer. According to the invention, pyrolysis and carbonization of straws can be effectively realized.
Description
technical field [0001] The invention relates to the technical field of straw treatment, in particular to straw pyrolysis and carbonization equipment. Background technique [0002] Biomass such as crop straw has problems such as light weight, large volume, wide distribution, and difficult collection, which makes the utilization of straw difficult and costly. The field purchase price of straw is usually much lower than the factory price. The main reason for this phenomenon is that the straw collection process needs to pay for labor, transportation and straw storage. Straw collection is labor-intensive, and manual collection results in lower collection efficiency and higher labor costs. In addition, due to the seasonal characteristics of straw collection, it is difficult to provide more stable job opportunities. In fact, the collection, transportation and storage of straw have not yet formed a stable industrial chain, which further increases the cost of straw collection. In...
