Abstract

The invention provides a white water three-stage purification system for paper-making reconstituted tobacco and a purification method of the white water three-stage purification system, and belongs to the technical field of sewage purification. A white water three-stage purification system for paper-making reconstituted tobacco comprises a first-stage filtering section, a second-stage filtering section and a third-stage filtering section which are sequentially arranged, and the first-stage filtering section comprises a slushing white water barrel used for diluting concentrated white water, a water seal water tank communicated with the slushing white water barrel and a first mechanical mesh type filter communicated with the water seal water tank; the secondary filtering section comprises a dilute white water tank, a second mechanical mesh filter and a clarification water tank which are communicated with the first mechanical mesh filter; and the third-stage filtering section comprises a mechanical membrane filter and an ultra-clean water tank. The invention further discloses a purification method of the system. The white water purification device is high in purification capacity, white water can be subjected to graded purification, one-step dilution and next-step purification are performed when the white water enters a next purification system, the purification effect guarantee capacity is high, and the purification stability is high.

Description

technical field [0001] The invention belongs to the technical field of sewage purification, and in particular relates to a white water three-stage purification system and a purification method for reconstituted tobacco leaves by a papermaking method. Background technique [0002] Paper-making reconstituted tobacco is a regenerated product in the form of flakes or filaments made of discarded tobacco stems, tobacco dust, and shredded tobacco pieces during cigarette processing using papermaking system technology. [0003] Paper-making reconstituted tobacco is an important tobacco raw material manufactured from tobacco waste. The manufacturing process involves heating extraction, concentration, pulping, papermaking, coating, and drying of tobacco raw materials. During the processing, due to Involving the extraction, separation and heating process, due to incomplete extraction and loss in the processing process, the reconstituted tobacco leaves are quite different from tobacco ra...
