The world's unique continuous steam explosion production

Bamboo fiber

The national patent technology production line has been put into operation in Hekou County of Yunnan. Chemical pulping process is a traditional process. It has the largest proportion of pulp production and good product quality, but the process has long process and high production cost. The most important thing is that the production process produces a large amount of sewage, which has great environmental pressure.

The mechanical pulping process does not require chemical agents. The sewage discharge is enlarged to reduce, but the electricity consumption is large, and the pulp quality is inferior to that of chemical pulp.

Explosion pulping is a new technology. Its principle is that the raw materials (wheat straw, rice straw and bagasse) are crushed in a closed container and compressed (compressed air and steam). Then the pressure is suddenly released. After sudden pressure relief, there is a large pressure difference between the inside and outside of the raw material, which makes the raw materials burst (similar to popcorn) and splits into fine fibers (instantly completing the pulping process).

The process has the advantages of simple process, less investment, easy source of raw materials, no pollution, and can easily get pulp from the packaging industry.

With the vigorous promotion of the industrial policy of circular economy, new technologies, new processes and new equipment have been springing up in various fields. Among them, the new technology and equipment for pulping and pulping in the pulping industry is continuous cooking, pressurized and pulping and pulping equipment, and our company's shareholder, Mr. Xue, has obtained the national patent (Patent No. 200520130307.X).

The existing blasting pulping technology is intermittent high temperature vapor phase blasting (including high pressure and low pressure blasting).

Because cooking and explosion pulping are carried out in the same equipment, the cooking temperature and bursting pressure can not be controlled independently.

Blasting is not enough, high pressure raw materials are easy to carbonization, quality is difficult to control.

At the same time, the cooking equipment runs in cyclic pressure and pressure relief fatigue load, which reduces the safety factor and service life of the equipment.

The latest continuous cooking and pressure spraying and pulping equipment provides a complete set of technical equipment, which uses wheat straw, rice straw and bagasse as main raw materials, and uses low pressure saturated steam as medium, and uses high pressure compressed air to pressurize and explode. It is a complete set of technical equipment for continuous pulping and pulping and producing pulp. It solves the problems existing in the domestic existing blasting pulping technology, such as not continuous production, temperature and pressure can not be independently controlled, product quality is unstable, cooking equipment is running fatigue, chemical method pulping seriously pollutes the environment, mechanical method pulping is invested heavily, and energy consumption is high.

In addition, the continuous cooking and pressurized pulping process is carried out in two different pressure vessels. The cooking temperature and pressure are independently controlled. The best technological parameters can be selected to ensure the stability of the product quality and the safety of the equipment.

The beneficial effects of this technology and equipment are: in the whole process of pulping, without any chemical raw material, continuous cooking and pulping, no pollution, zero discharge, stable product quality, stable operation of the cooking equipment, safety and reliability, accord with the circular economy industrial policy of sustainable development of national energy conservation and consumption reduction and waste resource utilization.

The production line of ten thousand tons of bamboo fiber produced by this patented technology will soon be put into operation. It is a unique production line in the world. It has many advantages compared with similar technologies at home and abroad, and has a guarantee for the production of bamboo fiber and plant fiber technology in China.
