Continuous rotary biomass pyrolytic charring and boiler heat supply integrated equipment

Abstract

The invention discloses continuous rotary biomass pyrolytic charring and boiler heat supply integrated equipment. The equipment comprises raw material conveying equipment, a rotary drying furnace and a rotary charring furnace, and is characterized in that: the raw material conveying equipment is connected with the rotary drying furnace and connected with the rotary charring furnace through a star-like feeder; a material which is pyrolytically charred by the rotary charring furnace is discharged through a charred material outlet; the rotary charring furnace comprises a hearth and a rotary furnace; one path of high-temperature hot gas produced by combustion of an oxygen-containing combustion chamber is conveyed into the hearth of the rotary charring furnace through a flue to enter a charring section; the rotary furnace comprises a barrel, an inner heating tube and a baffle ring; one end head of the inner heating tube is fixed on the barrel wall on one side and passes through the baffle ring to be fixed on the barrel wall on the other side of the baffle ring; after the high-temperature hot gas passes through the hearth through the flue, certain high-temperature hot gas enters one end head of the inner heating tube, is discharged out of the other end head of the inner heating tube, enters a waste heat conveying pipe and is conveyed into the rotary drying furnace through an induced draught fan; and the high-temperature hot gas is conveyed into a biomass boiler through another flue. The equipment can improve the working efficiency of the rotary charring furnace.

Description

Technical field: [0001] The invention relates to a device for integrating biomass pyrolysis carbonization and boiler heating, in particular to a continuous rotary biomass pyrolysis carbonization and boiler heating integration device. Background technique: [0002] Wood and bamboo processing enterprises currently use the residual biomass processed by themselves as fuel for their boilers. During the combustion process of biomass boilers, due to equipment reasons, the combustion is incomplete, the thermal efficiency is low, and it causes emission pollution. [0003] For biomass raw materials with large particle size, because of their good air permeability, internal heating vertical pyrolysis carbonization furnaces are often used. This equipment has high efficiency and simple equipment, but it cannot be used to produce raw materials with poor air permeability such as sawdust and wood shavings. Rotary continuous carbonization furnace has been adopted, but there are disadvantages ...

AI Technical Summary

Problems solved by technology

[0002] At present, wood and bamboo processing enterprises mostly use the residual biomass processed by themselves as fuel for their boilers. During the combustion process of biomass boilers, due to equipment reasons, the combustion is incomplete, the thermal efficiency is low, and it causes emission pollution.

[0003] For biomass raw materials with large particle size, because of their good air permeability, internal heating vertical pyrolysis carbonization furnaces are mostly used. This equipment has high efficiency and simple equipment, but it cannot be used to produce raw materials with poor air permeability such as sawdust and wood shavings.

Rotary continuous carbonization furnace has been adopted, but there are disadvantages such as low work efficiency; therefore, a pyrolysis carbonization technology using biomass is designed, and the wood gas produced by pyrolysis carbonization can be provided to the The biomass boiler is the object of the present invention
