Embodiment Construction

[0045] The herbal fiber in the present invention refers to fibers such as various hemp plants such as hemp, ramie, kenaf and cotton fiber. In the process of biorefining of fine herbal fiber, especially in the inactivation and water treatment process, a large amount of fiber and pectin will be produced, and the fiber and pectin will be mixed in water to form a waste liquid. If the waste liquid is directly discharged into the water area, it will cause The water, fiber and pectin are wasted, and at the same time, it will cause serious pollution to water areas.

[0046] The method for recycling and utilizing the waste liquid of the herb fiber biorefining process provided by the invention is used for treating the waste liquid generated during the herb fiber biorefining process. Include the following steps:

[0047] (1) Solid-liquid separation is performed on the waste liquid of the water treatment device c and the inactivation device b, and the obtained solid is extracted. The li...

Abstract

The invention discloses a method and equipment for recycling and utilizing the waste liquid of the herb fiber biorefining process, which is used for treating the waste liquid generated in the herb fiber biorefining process, including the following steps: (1) the water treatment device and the inactivation device (2) separate and extract the fibers in the solids; (3) dehydrate the fibers and package them; (4) extract the lumps in the solids Separated from the sediment; (5) dehydrating and packing the lumps. The technical problem to be solved by the present invention is to overcome the disadvantage of polluting the environment by waste liquid produced in the existing herb fiber production process, and to provide a method and equipment for recycling and utilizing waste liquid in the herb fiber biorefining process.

Description

technical field [0001] The invention relates to the field of herbal fiber biorefining. Specifically, the invention relates to a method and equipment for recycling and utilizing waste liquid of a herbaceous fiber biorefining process. Background technique [0002] Extracting fibers from herbaceous fiber raw materials has been used as a basic material for textiles, papermaking, and biomass industries for thousands of years. The "retting" method, which has been followed for thousands of years, is to cut the stems of herbaceous fiber plants into natural stacks in the field or transport them and soak them in natural water bodies such as rivers, lakes and ditches, and peel off non-fibers under the random degradation of natural flora However, there are problems such as unsuitable for industrialized production, unstable fiber output and quality, high labor intensity and harsh environment (almost no one is willing to engage in the farming work of "retting"), especially with the vigoro...
