Embodiment 1

[0017] Modular coupled biomass microwave dry or semi-dry pretreatment reactor for processing 100kg of wheat straw per hour.

[0018] as attached figure 1 , the driving motor 1 drives the spiral material agitator 16 to rotate through the reducer 2 . After the material enters the spiral material agitator 16 from the feeding bin 3, according to the needs of water content adjustment, a certain amount of tap water is input from the water tank 4 to adjust the water content of the material to 30% (w / w). Controlled by the flow control solenoid valve 5, the moisture content of the material is adjusted during the operation of the spiral material agitator 16, and the distribution of the moisture also becomes uniform. The material is output from the end of the spiral material agitator 16 and falls onto the conveyor belt 18, which is made of glass wool coated with Teflon. Conveyor belt 18 is driven by conveyor belt drive wheel 11, and conveyor belt driven wheel 14 is also configured in a...

Embodiment 2

[0021] Modular coupled biomass microwave dry or semi-dry pretreatment reactor that processes 150kg of corn stalks per hour.

[0022] as attached figure 1 , the driving motor 1 drives the spiral material agitator 16 to rotate through the reducer 2 . After the material enters the spiral material agitator 16 from the feed bin 3, according to the needs of water content adjustment, a certain amount of tap water is input from the water tank 4 to adjust the water content of the material to 28% (w / w), and the amount of water added is determined by Controlled by the flow control solenoid valve 5, the moisture content of the material is adjusted during the operation of the spiral material agitator 16, and the distribution of the moisture also becomes uniform. The material is output from the end of the spiral material agitator 16 and falls onto the conveyor belt 18, which is made of polyamide. Conveyor belt 18 is driven by conveyor belt drive wheel 11, and conveyor belt driven wheel 14...

Embodiment 3

[0025] Modular coupled biomass microwave dry or semi-dry pretreatment reactor for treating 50kg of field weeds per hour.

[0026] as attached figure 1, the driving motor 1 drives the spiral material agitator 16 to rotate through the reducer 2 . After the material enters the spiral material agitator 16 from the feed bin 3, according to the needs of water content adjustment, a certain amount of tap water is input from the water tank 4 to adjust the water content of the material to 25% (w / w). Controlled by the flow control solenoid valve 5, the moisture content of the material is adjusted during the operation of the spiral material agitator 16, and the distribution of the moisture also becomes uniform. The material is output from the end of the spiral material agitator 16 and falls onto the conveyor belt 18, which is made of polyamide. Conveyor belt 18 is driven by conveyor belt drive wheel 11, and conveyor belt driven wheel 14 is also configured in addition to the drive wheel....

Abstract

The invention discloses a module coupling biomass microwave dry or semidry pretreatment reactor, which structurally comprises a material continuous input system, a material humidity regulating system, a microwave treatment system and a material output system after pretreatment. In the invention, a material is continuously conveyed through a spiral material stirrer and is continuously regulated ina required humidity range through the material humidity regulating system; moisture is uniformly distributed; and the material after humidity control is subjected to wall breaking treatment through early preheating and back-end high-power microwave in the microwave treatment system and is exported through the material output system, so that continuous pretreatment of biomass is realized. The system is of module coupling; and a plurality of systems can be connected in parallel for use to increase treatment speed and treatment capacity and can also be connected in series for use to meet the special pretreatment requirement of some biomasses. Through the reactor, continuous pretreatment of the biomass under normal pressure is realized; the equipment investment is low; the energy consumption is low; the speed is high; and the pretreatment cost is greatly reduced.

Description

technical field [0001] The invention belongs to the field of biochemical industry, in particular to a modular biomass microwave dry or semi-dry pretreatment reactor. Background technique [0002] With the increasing depletion of petrochemical resources, the demand for energy and resources in the development of human society will inevitably transform from petrochemical resources to renewable resources. Biomass is a renewable resource with a huge output on the earth. If it can be well utilized, it is possible to meet a large part of human needs for resources and energy. Therefore, the importance of biorefinery has become increasingly prominent, and a core issue of biorefinery is the pretreatment of biomass. Biomass raw materials, especially lignocellulosic raw materials, can only be economically and effectively utilized after proper pretreatment . At present, there are various biomass pretreatment methods and corresponding pretreatment reactors, but these methods and reactor...
