Problems solved by technology

[0005] In order to overcome the fact that the papermaking water existing in the existing similar technology cannot be reused in the papermaking reconstituted tobacco production process, a large amount of this treated water will cause certain pollution to the environment, and at the same time cause low water utilization in the production process and water consumption. Big defect, the purpose of the present invention is to disclose a kind of processing method that the remanufacturing water circulation uses in the reconstituted tobacco leaf production process of improvement, can overcome the defect of prior art

Embodiment 1

[0019] The processing method for recycling water in the reconstituted tobacco leaf production process is characterized in that the method steps are:

[0020] ①. Filtrate and recycle the fiber from the papermaking water produced in the papermaking process of reconstituted tobacco leaf production, and then import it into a sedimentation tank or a sedimentator for sedimentation treatment, and take 54.0Kg of the supernatant overflow liquid after the sedimentation treatment;

[0021] ②. The supernatant overflow liquid is introduced into the ultrafiltration membrane separation system for separation. The membrane element of the ultrafiltration membrane separation system adopts an ultrafiltration membrane with a separation pore size of 10-200nm. The operating pressure of the ultrafiltration membrane separation system is controlled at 0.3MPa. The feed liquid temperature is controlled at 23-35°C, the membrane surface velocity is controlled at 5m / s, and 51.2Kg of dialysate and 2.8Kg of co...

Abstract

The invention relates to a treating method of paper-making water recycling use in the production process of reconstituted tobacco, aiming at solving the problems that the massive discharge of treated water in the prior art causes pollution to the environment as well as low utilization ratio of water for production and large new-water consumption. The technical key points are characterized by carrying out fiber recovery on the paper-making water, then carrying out sedimentation, leading supernatant overflowing liquid after sedimentation into an ultrafiltration membrane separating system for separation, obtaining dislysate and concentrate, leading the dislysate into a reverse osmosis membrane system for separation again, obtaining purified water and concentrated water; the purified water is reused for water in the production process after treatment of removing off-odor, the recovered fiber is reused into the production process, the sediment is used as solid waste, the concentrate and the concentrated water are treated properly, the ultrafiltration membrane separating system adopts an ultrafiltration membrane with the bore diameter of 10-200nm, the pressure is 0.1-0.5MPa, the temperature of the feed liquid is 10-70 DEG C, the speed of the membrane surface is 2-8m / s, the pressure of the reverse osmosis membrane system is 1.0-10MPa, the temperature of the feed liquid is 20-45 DEG C, and the speed of the membrane surface is 2-7m / s.

Description

technical field [0001] The invention belongs to the technical method of the cigarette production process, in particular to the method for processing the reconstituted water in the process of producing reconstituted tobacco leaves by the papermaking method so as to be recycled. Background technique [0002] The current cigarette production is different from the traditional production method. One of its characteristics is to add a certain amount of reconstituted tobacco shredded tobacco into the shredded tobacco to improve the use characteristics and processing performance of cigarettes and reduce waste and pollution. The amount generally can reach 20-30%. Reconstituted tobacco leaves are also called tobacco flakes, reconstituted tobacco leaves, or homogeneous tobacco leaves. The production method of reconstituted tobacco leaves by papermaking method is to use tobacco materials such as tobacco powder, tobacco stems, tobacco leaf fragments, and waste tobacco leaves as the main...
