Hereinafter, water-saving rate can reach 95% or more, it is difficult to solve the larger wastewater treatment of water consumption in original pulping technique production process
The problems such as, new equipment not only can be as needed water water supply, but also accomplished industrial water zero-emission, press master water follows
Loopback supply, energy conservation and environmental protection；
High-efficiency environment friendly: a whole set of production equipment is without any pollution, and no chemicals, additive, recirculated water is in pulping process
It is utilized by Infinite Cyclic, the raw material impurity by being removed except iron forms the circulatory system efficiently utilized for raising earthworm.
2, in pulping process, to reach processing lignin and removing fiber, the bonding force of lignin in pulping raw material is cracked
Process, the present invention is crushed by the high temperature sub-wire of squeeze crack thread rolling machine under closed system, the high temperature of fiberizer is tormented in conjunction with inclined screw
The insulation effect of conveying, the effect that can effectively replace chemical pulping dissolves out lignin, the present invention combine raw material using machining
The heat preservation of conveying is arranged, and controls under specific temperature conditions, effectively weakens lignin lateral consolidation force between fiber, make lignin by
Hard and crisp glass transition is partially soft rubbery state；At the same time, raw material is placed in the operating of closed system high speed to torment, is made
Material tears under instantaneous high-temperature state, conquassation, brooming, profit rise, to obtain good slurry.
3, existing pulping equipment and technology be by high temperature and pressure boiling compounding aid slurrying, in process of production Chan Sheng ?
Liquid, processing cost is high, and the present invention can effectively avoid the production of black liquor by the slurrying of Iron removal by two steps device cooperative mechanical and attemperator
It is raw.In deironing apparatus, not only iron content class impurity can be removed except iron for one section, but also two sections are made except iron with more fine sorting
With the impurity such as iron content class fine particle can be removed, avoid raw material bring black liquor problem hidden danger in front-end processing, not only
Environmental protection and cost is greatly reduced, simultaneously, slurry appearance is preferable, can show raw material true qualities completely, does not occur dark turbid etc.
Phenomenon.
4, the diversity choice of raw material: pulping equipment of the invention is applicable not only to the system of wheat straw, straw, reed raw material
Slurry, and could be applicable to the slurrying of discarded wood chip, there is the high temperature sub-wire of unique squeeze crack thread rolling machine just because of the present invention
The high temperature of effect combination fiberizer torment with inclined screw conveying insulation effect, allow the pulping process be effectively treated including
Stalk fibre, wood fibre etc. difference fibre structure raw material, use identical equipment and technique, identical power consumption and
While water consumption, the slurry of phase homogenous quantities is prepared, is significantly effectively reduced cost of material.
5, widely used, strengthening material performance effectively reduces cost: being produced using the slurry of equipment provided by the invention preparation
Product can be widely used for corrugated paper, Gong Bao, plate, tableware etc..
