Description

A dry pulp production line

technical field

The invention relates to the technical field of pulping, in particular to a dry pulp production line.

Background technique

As we all know, my country is a big country in papermaking. The total annual output of various paper and cardboard exceeds 73.5 million tons. For this year, various fiber resources will exceed 70 million tons. However, my country is also a country with a shortage of forest resources. Fiber resources for papermaking extremely scarce. In order to meet the demand for papermaking, my country needs to import more than 20 million tons of waste paper and more than 8 million tons of virgin wood pulp annually. However, with the promulgation of the most stringent environmental protection laws in my country in recent years, especially since January 2019, my country has fully launched the "ban and abolition order". Solid waste, including paper product waste, prevents a large amount of foreign waste paper from entering the domestic market through customs, but at the same time, there is a huge domestic demand for waste paper pulp, and the price of pulp remains high. The fundamental reason why foreign waste paper cannot be imported into China is that waste paper is mixed with a large amount of other garbage and cannot pass the customs inspection. How to process the waste paper to meet the requirements of my country's customs clearance is an urgent problem that needs to be solved at present.

In the waste paper pulping process of the prior art, the process design is complicated and the equipment configuration is numerous. The general situation is to configure a complete LOCC processing line and a complete AOCC processing line. LOCC treatment line includes waste paper disintegration, high-concentration slag removal, coarse screening, primary and secondary classification, and long, medium and short fiber treatment lines; AOCC treatment line includes waste paper disintegration, high-concentration slag removal, coarse screening, primary Classification and long and short fiber processing lines; the long, medium and short fiber processing lines are composed of low-concentration sand removal, fine screening, multi-disc concentration, thermal dispersion, and disc grinding and beating. When using full LOCC production, the AOCC production line equipment is idle and unused; when using AOCC and LOCC mixed production, the LOCC production line is not in full-load production, and the actual production capacity of the LOCC line is the design production capacity of the LOCC line after deducting the design production capacity of the AOCC line. capacity, and the utilization rate of equipment capacity is low.

In view of this, it is necessary to improve the waste paper pulping process of the existing technology, reduce the restrictions on production equipment and production sites, and also be conducive to environmental protection, reduce the generation of sewage and waste gas, and at the same time make the produced pulp meet the requirements of our country. customs clearance requirements.

In the above technical solution, in view of the country's existing "banning waste", we can build factories in neighboring countries in Southeast Asia, and firstly remove the US waste and European waste (the main source of domestic waste paper pulping in the past) that cannot pass through the customs. After being transported to the factory for weighing, it is transported to the manual sorting area by forklift, and the impurities such as adhesive paper and metal in the waste paper are sorted out manually, and then the waste paper is transported to the waste paper crusher through the belt conveyor, and the waste paper is passed through the crushing knife. The waste paper is crushed, and the dust generated during crushing is sealed by setting a cover and a dust-proof feeding chute to prevent the dust generated during production from overflowing. The waste paper is decomposed into fluffy flocs through the continuous crushing action of the crushing knife. Fiber-like, and then through pulse dust removal, the short fibers formed during the crushing process and the dust generated are removed, and finally the waste paper fibers after pulse dust removal are packaged into squares by a hydraulic baler, and packaged. After the above operations, after simple processing, waste can be turned into treasure, and the waste paper waste that cannot pass through customs (can not pass through customs) can be turned into initially processed waste paper pulp (pulp is allowed to be imported in my country), and The quality of the waste paper pulp after preliminary treatment is much higher than that of the currently recycled waste paper in China.
