Description

Herbal fiber bio-refining process waste residue treatment method and equipment

Technical field

The present invention relates to the field of herbal fiber biorefinery. Specifically, it is a method and equipment for treating waste residue of herbal fiber bio-refining process.

Background technique

The extraction of fiber from herbal fiber raw materials has been used as a basic material for the textile, paper and biomass industries for thousands of years. The “ramie” method that has been inherited for thousands of years—cut the stalks of herbaceous fiber plants into natural piles in the field, transport them and soak them in natural water bodies such as rivers and lakes, and strip non-fibres under the random degradation of natural flora. There are problems such as unsuitable industrial production, unstable fiber production and quality, high labor intensity and harsh environment (almost no one is willing to engage in “rice” farming). In particular, the contradiction between China and the booming aquaculture industry is becoming more and more prominent. The loss of more than 40% of the raw materials in the water body is causing serious “face pollution” to the environment and is facing a crisis that has been eliminated by history. The chemical method of “cooking of caustic soda solution” is based on the fact that more than 35% of the raw materials (including a large amount of non-cellulosic and a little cellulose with low crystallinity) are hydrolyzed into monomer components, resulting in COD in high-concentration wastewater. With a value exceeding 10,000 mg/L, its application surface is being severely limited. The transitional "bio-chemical combination" method invented in 1985, because there is no mechanism to get rid of the chemical hydrolysis, so that the COD value in the high concentration wastewater is maintained at about 10000 mg / L. The modern biological method of "key enzyme directed cleavage of non-cellulose" invented in 1995 has not yet shown a strong driving force to promote the industrial technological revolution because it does not well break the constraints of "process and equipment support".

The applicant obtained the invention patent authorization of “a method for rapidly extracting herbal fiber from a functional strain for industrial fermentation”, and applied for “a standard equipment and method for preparing herbal fiber raw materials” and “a bio-refined herb”. A series of patents such as the automated operation system and method of fiber, these technical solutions fundamentally solve the key technologies of modern biotechnology in the application of herbal fiber manufacturing. However, in the process of standardizing the preparation of herbal fiber raw materials, the xylem (the hemp-like agricultural products are called “hemp bones”) and the epidermis (the hemp-like agricultural products are called “hemp shells”) attached to the fibrous agricultural products are mechanically compacted. The cellulose turns into pieces and forms industrial waste. At the same time, in the drying process of the refined fiber, the free water (about 35%) contained in the refined fiber is heated into steam to form industrial waste steam. These industrial wastes and waste steam industry have become new problems in the manufacture of herbal fiber. There is no suitable method to solve it.
