Economic and environmental friendly technology for manufacturing cardboard paper and straw boards by using straws

Abstract

The invention discloses an economic and environmental friendly technology for manufacturing cardboard paper and straw boards by using straws, belonging to the field of papermaking methods; the economic and environmental friendly technology sequentially comprises the following steps of: a. smashing crop straws into pieces; b. adding the smashed straws to a grinding and splitting machine to be ground into crude fibers; c. adding water to the crude fibers generated by the grinding and splitting machine, and entering into a pulping machine for producing pulp; d. pressing the paper pulp produced by the pulping machine into the cardboard paper and straw boards; and e. recycling papermaking tail pulp wastewater as water used in the step in the step c. The economic and environmental friendly technology realizes the pollution-free manufacturing of the cardboard paper and the straw boards by using the straws under the condition of very simple working procedures, very little personnel and equipment funds investment, and very low production cost and energy consumption.

Description

technical field [0001] The invention belongs to the field of papermaking methods. Background technique [0002] my country's agriculture covers a large area, and a large amount of crop straw will be produced in the process of crop production. Although some simple reprocessing work has begun to use straw for organic fertilizers, domestic fuels, livestock feed, edible fungus base materials, and industrial raw materials. , but at present, due to the constraints of various factors such as the shortage of rural labor force and the high cost of comprehensive utilization of straw, most of the straw is still directly burned back to the field or discarded in the wild, which not only wastes resources, pollutes the environment, but also affects people's health. At present, a relatively large number of complex straw reprocessing methods are recycled papermaking, but the existing straw papermaking process has complex processes, huge investment in personnel and equipment, high production c...

Problems solved by technology

[0002] my country's agriculture covers a large area, and a large amount of crop straw will be produced in the process of crop production. Although a small amount of simple reprocessing work has begun to use straw for organic fertilizers, domestic fuels, livestock feed, edible fungus base materials, and industrial raw materials. , but at present, due to the constraints of various factors such as the shortage of rural labor force and the high cost of comprehensive utilization of straw, most of the straw is still directly burned back to the field or discarded in the wild, which not only wastes resources, pollutes the environment, but also affects people's health

At present, a relatively large number of complex straw reprocessing methods are recycled papermaking, but the existing straw papermaking process has complex processes, huge investment in personnel and equipment, high production costs, and high energy consumption. During the production process, a large amount of black liquor papermaking wastewater will be generated. , causing huge pollution to the environment

However, the treatment cost of this kind of papermaking wastewater is high and the treatment effect is poor. At present, there is no method that can solve the sewage pollution of straw raw material paper mills.
