According to the biomass of the utility model embodiment and coal copyrolysis reactor 100, by the way that the first biomass thermal is arranged Cylinder 1 and the second biomass pyrolytic cylinder 3 are solved, the treating capacity of biomass pyrolytic is improved.Moreover, by the second biomass thermal It solves and thermal insulating material materials and parts 33 is set on the outer wall of cylinder 3, so as to the high-temperature oil gas generated using the pyrolysis of pyrolysis of coal cylinder and half Burnt sensible heat provides required heat for the biomass pyrolytic in the second biomass pyrolytic cylinder 3, without to the second biomass pyrolytic Pyrolysis heat source is provided separately in cylinder 3, reduces energy consumption, reduces costs, and passes through 3 endogenous substance of the second biomass pyrolytic cylinder The heat absorption of pyrolysis can reduce the temperature of coal such as low-order coal pyrolysis oil gas, can reduce secondary response, sufficiently so as to mention High pyrolysis of coal tar yield.

In addition, by the way that the first biomass pyrolytic cylinder 1 is arranged in the top of pyrolysis of coal cylinder, and make the first biomass thermal The cross-sectional area of solution cylinder 1 and the second biomass pyrolytic cylinder 3 is respectively less than the cross-sectional area of pyrolysis of coal cylinder, the richness in biomass Hydrogen can be effectively transferred in coal, and biomass and coal synergistic effect are obvious, improve the converting rate of coal, and the second pyrolysis The intracorporal biomass of cylinder can be smoothly pyrolyzed.

In addition, by being respectively arranged the more of uniform intervals setting in the first biomass pyrolytic cylinder 1 and pyrolysis of coal cylinder A heat accumulation type radiant tube 4 uses porcelain ball and thermal decomposition product semicoke as solid thermal carriers or product char Gasification with traditional Coal gas afterwards is compared as heating methods such as gas heat carriers, eliminates heat carrier and mechanical rotation device, process flow is simple, System temperature control is accurate, temperature adjustment is convenient, and heating, separation process without gas and solid thermal carriers reduce the failure rate of system.

Some embodiments according to the present utility model, the first biomass pyrolytic cylinder 1 and the second biomass pyrolytic cylinder 3 Diameter is respectively 20%~50% (including endpoint value) of the diameter of pyrolysis of coal cylinder.In other words, the first biomass pyrolytic cylinder The diameter of body 1 is 20%~50% (including endpoint value) of the diameter of pyrolysis of coal cylinder, the diameter of the second biomass pyrolytic cylinder 3 For 20%~50% (including endpoint value) of the diameter of pyrolysis of coal cylinder.First biomass pyrolytic cylinder 1, the second biomass at this time The cross-sectional shape for being pyrolyzed cylinder 3 and pyrolysis of coal cylinder is circle.Thus, it is possible to guarantee the first biomass pyrolytic cylinder well Body 1 and biomass in the second biomass pyrolytic cylinder 3 and the intracorporal pyrolysis of coal of pyrolysis of coal cylinder reach synergistic effect.

Specifically, for example, if setting makes the diameter of the first biomass pyrolytic cylinder 1 less than the diameter of pyrolysis of coal cylinder 20%, the diameter of the first biomass pyrolytic cylinder 1 is smaller at this time, possibly required environment rich can not be provided for pyrolysis of coal；Such as Fruit setting makes the diameter of the first biomass pyrolytic cylinder 1 greater than the 50% of the diameter of pyrolysis of coal cylinder, may not can guarantee biology Matter and pyrolysis of coal reach good synergistic effect.That is, making the diameter coal of the first biomass pyrolytic cylinder 1 by setting It is pyrolyzed the 20%~50% of the diameter of cylinder, while guaranteeing to provide required environment rich for pyrolysis of coal, can effectively be protected Card biomass and pyrolysis of coal reach good synergistic effect.

If the 20% of the diameter for making the diameter of the second biomass pyrolytic cylinder 3 be less than pyrolysis of coal cylinder is arranged, at this time the The diameter of two biomass pyrolytic cylinders 3 is smaller, and the biological quality that can be handled is less, thus intracorporal downwardly into pyrolysis of coal cylinder Hydrogen is also less；If the 50% of the diameter for making the diameter of the second biomass pyrolytic cylinder 3 be greater than pyrolysis of coal cylinder is arranged, although energy More biomass is accommodated, but the high-temperature oil gas of pyrolysis of coal cylinder pyrolysis generation and semicoke sensible heat possibly can not be by all biologies Matter is pyrolyzed completely, causes to be pyrolyzed insufficient.In other words, the diameter pyrolysis of coal of the second biomass pyrolytic cylinder 3 is made by being arranged The 20%~50% of the diameter of cylinder, it is ensured that relatively large number of biomass in the second biomass pyrolytic cylinder 3 has been carried out Full pyrolysis, and biomass and pyrolysis of coal is made to can achieve good synergistic effect.
