Embodiment 1

[0085] Embodiment 1: This embodiment is only heated to the stage of pyrolysis and carbonization, mainly to obtain finished charcoal:

[0086] A high-efficiency optional pyrolysis system, including a furnace body 1, a dry distillation furnace 2, a gas nozzle 3 and a cooling device 5, a dry distillation furnace 2 is arranged in a furnace chamber 11 in the furnace body 1, and the dry distillation furnace 2 is horizontal Arrangement, including an upper side 21, a lower side 22, a top 23 and a bottom 24, the upper side 21 and the lower side 22 are located between the top 23 and the bottom 24, and the upper side 21 is close to the top The position of 23 communicates with one end of the exhaust pipe 4, and the other end of the exhaust pipe 4 is connected with the release valve 41 positioned at the outside of the body of heater 1 after the body of heater 1, and the position near the exhaust pipe 4 on the body of heater 1 is provided with The thermometer 6 communicating with the furnac...

Embodiment 2

[0094] Embodiment 2: This embodiment continues heating to the calcination stage, mainly to obtain biomass gas:

[0095] The basic content is the same as in Example 1, except that the method of use also includes a calcination stage between the pyrolysis carbonization stage and the cooling charcoal collection stage, and the calcination stage is an endothermic reaction;

[0096] The calcination stage refers to: when the pyrolysis and carbonization stage ends, continue to heat the retort 2, and enter the calcination stage when the temperature in the furnace chamber 11 is observed to rise to 500°C from the thermometer 6. In the calcination stage, the finished charcoal A reduction reaction occurs, and the reaction equation is C+CO 2 =2CO, C+H 2 O=H 2 + CO, and collect the gas produced in the calcination stage through the exhaust pipe 4. When the temperature in the furnace chamber 11 is observed from the thermometer 6 to rise to the set temperature, the calcination stage ends, and ...

Abstract

The invention discloses an efficient selectable pyrolysis system and a using method thereof, wherein the efficient selectable pyrolysis system comprises a furnace body, a dry distillation kettle, gas nozzles and a cooling device, wherein a furnace chamber in the furnace body is internally provided with the horizontally-arranged dry distillation kettle, wherein the dry distillation kettle comprises an upper side part, a lower side part, a kettle top and a kettle bottom; the part on the upper side part close to the kettle top is communicated with an exhaust pipe; the other end of the exhaust pipe is connected with a diffusion valve; the part on the furnace part close to the exhaust pipe is provided with a temperature meter communicated with the furnace chamber; the lower part of the lower side part is communicated with gas outlets of four staggered gas nozzles; the gas outlets of the gas nozzles are connected with a control valve; the cooling device comprises a nitrogen intake pipe and a nitrogen exhaust pipe, wherein the nitrogen intake pipe is communicated with the kettle top; the nitrogen exhaust pipe is communicated with the upper side part; and when the efficient selectable pyrolysis system is used, if carbon production is emphasized the heating is finished to pyrolysis carbonization stage, and if biomass gas production is emphasized, the heating is finished to the forging stage. The design not only has good adjustability, high cost performance and high heating efficiency, but also the finished product carbon has good quality and high production efficiency.

Description

technical field [0001] The invention relates to a biomass dry distillation equipment, in particular to a high-efficiency selective pyrolysis system and its use method, which are specifically suitable for improving the quality of finished charcoal and obtaining cost-effective biomass gas. Background technique [0002] With the rapid development of society, the demand for energy is also increasing, but the reserves of traditional fossil energy (coal, oil, natural gas) are decreasing day by day, and they have relatively large pollution, which cannot meet the needs of social development, so it is urgent to find new ones. Alternative Energy. Biomass has the characteristics of wide distribution, sustainable supply, and convenient transformation. It is very suitable for my country's national conditions and has a good application prospect. The biomass pyrolysis system is developed under this background. [0003] The Chinese patent authorization announcement number is CN201241088Y, ...
