Abstract

The invention discloses a lignin filtration and settlement system. The lignin filtration and settlement system comprises a raw material storage tank and a filtrator, wherein the raw material storage tank and the filtrator are connected through a charging pipe, and a discharging pipe is arranged at the bottom of the filtrator and is sequentially connected with a flocculation basin and a settling basin. According to the lignin filtration and settlement system, micromolecular cellulose in concentrate is subjected to thorough flocculation and settlement, and thus, macromolecular cellulosic materials beneficial to human bodies are obtained.

Description

technical field [0001] The invention relates to a sedimentation separation system, in particular to a lignin filtration sedimentation system. Background technique [0002] Fiber plays an important role in maintaining a healthy digestive system, and getting enough fiber can also prevent cardiovascular disease, cancer, diabetes, and other diseases. Fiber can clean the digestive wall and enhance digestive function. Fiber can also dilute and accelerate the removal of carcinogens and toxic substances in food, protect the fragile digestive tract and prevent colon cancer. Fiber slows down digestion and excretes cholesterol the fastest, so blood sugar and cholesterol in the blood can be controlled at optimal levels. As the most abundant biological resource in the world, lignin has attracted much attention due to its renewable, green and clean advantages. Therefore, it is of great significance to extract dietary cellulose from lignin. However, after acid hydrolysis or alkali hydrol...
