Biomass solid gas preparation system

Abstract

The invention relates to a biomass solid gas preparation system. The biomass solid gas preparation system is characterized by comprising a drying furnace, a first screw conveyor, a mixing device, a second screw conveyor, a biomass solid gas carbonization system, a conveying device and a mill. A discharging port of the drying furnace is connected with a feeding port of the mixing device through thefirst screw conveyor, and an air outlet of the drying furnace is communicated with an inlet of a first dedusting system; the mixing device is provided with an additive adding port, and a dischargingport of the mixing device is connected with a feeding port of a pyrolysis device of the biomass solid gas carbonization system through the second screw conveyor. The biomass solid gas carbonization system includes the pyrolysis device, a burner, a cracking gas pipe, a liquid gas separator, a waste heat pipe, and a cracking gas collection hood. A discharging port of the pyrolysis device is connected with a feeding port of the mill through the conveying device. The system has the advantages of low energy consumption and low emissions.

Description

technical field [0001] The invention relates to a biomass solid gas preparation system. Background technique [0002] Biomass fuel can not only solve the air pollution caused by straw burning, but also replace fossil energy. At present, there are mainly two methods for biomass fuel production. The first is the physical method: the composition of biomass cannot be changed, and most of them are briquettes (granules); the disadvantage is that the heat quality is difficult to meet the requirements of industrial boilers, and the consequences of air pollution are the same as burning in the field. Coking damages the boiler. The second is to process and produce biomass gas or liquid fuel, but special pipelines or special transport vehicles are required to deliver the fuel to users. Even if the gas is delivered to users, many customers do not have the conditions for fire safety and use costs. At the same time, the biomass heat conversion efficiency is low, the cost performance is ...

The second is to process and produce biomass gas or liquid fuel, but special pipelines or special transport vehicles are required to deliver the fuel to users. Even if the gas is delivered to users, many customers do not have the conditions for fire safety and use costs. High, while the thermal conversion efficiency of biomass is relatively low, low cost performance, and poor implementability
