Problems solved by technology

For different types of plant fibers and different modification requirements, it may be necessary to select different modifiers and effectively regulate the reaction conditions of steam explosion parameters. Regulation puts forward higher requirements, but the current tank-type steam explosion device and single-screw steam explosion device are difficult to meet the above requirements

Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0038] Example.

[0039] like figure 1 as shown, figure 1 It is a schematic diagram of the structure of the invented modular counter-rotating twin-screw continuous steam explosion modification device for plant fibers. Modular counter-rotating twin-screw continuous plant fiber steam explosion modification device, its core is a modular steam explosion unit composed of barrel and twin-screw, figure 1 It includes the first-stage modular steam explosion unit 1, the second-stage modular steam explosion unit 7, and the third-stage modular steam explosion unit 11, which are respectively fixed on the three-section frame, and the frame passes through the positioning device and the fastening mechanism. It is fixed and easy to disassemble and assemble. It can be converted into a single-stage, t...

Abstract

The invention discloses a modularized counter-rotating twin screw continuous plant fiber steam explosion modifying device which is used for manufacturing plant fibers and modifying the plant fibers. A steam explosion device which is composed of multiple stages of modularized steam explosion units in a combined mode and is high in output, good in effect, wide in application range and easy to control automatically is adopted for the modularized counter-rotating twin screw continuous plant fiber steam explosion modifying device, wherein each steam explosion unit is composed of a machine barrel and twin screws. The modularized counter-rotating twin screw continuous plant fiber steam explosion modifying device mainly comprises the machine barrels and the screws installed in the machine barrels, two screws which are opposite in thread direction and mutually meshed are installed in each stage of machine barrel, and a spline mandrel is sleeved with all the screws on the same side; each modularized unit can achieve in-situ modification of the plant fibers according to the adjusting level number of material due to the fact that each unit is provided with a feeding port and a modifying agent can be added into each unit; each machine barrel is of a structure composed of an upper part and a lower part.

Description

[0001] technical field [0002] The invention relates to a steam explosion modification device in the pretreatment process of biomass raw materials, in particular to a plant fiber continuous steam explosion modification device with relatively high production efficiency. Background technique [0003] Biomass is widely used in the fields of paper pulping, alcohol fermentation, wood-based panels and wood-plastic composite materials, and proper pretreatment is conducive to the efficient utilization of plant fibers. At present, the pretreatment technologies for plant fibers mainly include mechanical pretreatment, chemical pretreatment, biological pretreatment and other technologies. The steam explosion technology based on physical-chemical action has attracted people's attention for its advantages of no pollution, low cost and good effect. [0004] There are two types of steam explosion devices: intermittent and continuous. Most of the current steam explosion devices are interm...
