Abstract

The invention discloses a movable internal heating and external heating combined biomass pyrolysis charcoal and tar co-production system, which mainly comprises a material hopper, an external source heating device, a pyrolysis gas backflash heating device, a water cooling device and rollers, wherein the external source heating device comprises a cyclone heat exchange chamber, a cyclone heat exchange plate, a heat exchange pipe and a three-way cross pipeline, the pyrolysis gas backflash heating device comprises an air regulation valve, an air flow rate meter, an igniter, a flame arrester and aflue gas purifier, the external source heating device provides an external heat source for material drying, the heat generated by the spontaneous combustion of the material provides an internal heat source for pyrolysis, the high temperature flue gas generated after the igniting of pyrolysis gas enters the external source heating device from the gas inlet at the side lower end of the external source heating device, dividing wall type countercurrent flow heat exchange is performed on the material so as to achieve the internal heating and external heating combination of the whole system, and therollers are arranged at the lower end of a bracket and is used for moving the whole system. The movable internal heating and external heating combined biomass pyrolysis charcoal and tar co-productionsystem of the present invention has advantages of convenient operation, convenient movement and high heat exchange efficiency.

Description

technical field [0001] The invention belongs to the technical field of renewable energy, and specifically relates to a mobile combined internal and external heating biomass pyrolysis charcoal-oil cogeneration system, especially the internal and external combined heating that can realize biomass pyrolysis, and is suitable for biomass pyrolysis charcoal-oil cogeneration system Production system development. Background technique [0002] Biomass carbonization technology can be divided into external heat type, internal heat type and spontaneous combustion type according to the heating mode of heat source. The external heat type pyrolysis carbonization furnace consists of two parts, the heating furnace and the carbonization furnace, which can precisely control the temperature, and the product quality is high, but this technology needs to consume other forms of energy, the heat exchange efficiency is low, and the heat conduction through the furnace wall surface cannot be guarantee...
