Description

technical field [0001] The invention relates to the field of papermaking industry, in particular to a fast and clean pulping production equipment. Background technique [0002] Among all kinds of industries in the world, the paper industry ranks third after telecommunications and automobiles. The pulp and paper industry is a raw material industry. Paper and cardboard are not only the necessities of people's life, but also ubiquitous light industrial raw materials. At present, there are three main problems restricting the development of the paper industry: one is the shortage of wood raw materials, while a large amount of crop straw is wasted; the other is the lack of water, and pulping is a production item that consumes a lot of water; the third is serious environmental pollution. [0003] At present, my country's paper industry is very harmful to environmental pollution, especially in the production process of paper pulp. Among the large amounts of wastewater discharged...

AI Technical Summary

Problems solved by technology

Due to the production process such as the cooking method, the production equipment is backward, and a large amount of alkali-containing wastewater will be produced in the production process.

If the equipment is transformed, not only the investment is large, but also the energy consumption is high, so some enterprises will secretly discharge the production wastewater into the river, river, and lake water, seriously polluting the water resources and polluting the environment
