Problems solved by technology

[0002] my country's paper products are mainly made of non-wood pulp structure raw materials, most of which use wheat straw and waste paper as raw materials. The traditional lime method produces pulp, which produces a large amount of pollutants. These pollutants are difficult to treat, and the treatment costs are high. causing loss, causing harm to the lives of the people
The traditional lime method and the blasting method currently used in papermaking cannot recycle the wheat grains, awns, and barley in the wheat straw, resulting in a large waste of resources. These substances enter the papermaking process and increase the pollution load
The high-pressure steam gas used in explosive papermaking is discharged into the atmosphere after cooking once, and is not reused, resulting in waste and polluting the air

Embodiment Construction

[0019] As shown in the accompanying drawings, the gas mixed explosion pulping equipment of the present invention consists of a feeder 1, a mower 2, a sorter 3, a dust collector 4, a digester 7,8, a feeder 11, an air pump 18, and The feeder 21 is formed. After the wheat straw is loaded into the feeder 1, the feeder 1 automatically feeds the wheat straw into the trimmer 2, and the wheat straw crushed by the trimmer enters the winnowing machine 3 through the feeding pipe 23 under the gravity of the wind , adjust the size of the damper of the winnowing machine, and change the wind speed, so that the soil and rocks in the wheat straw fall into the waste bin from the bottom of the winnowing machine, and the wheat straw, wheat leaves, wheat library, wheat awns, and dust enter through the feeding pipe 5 under the gravity of the wind In the feeding chamber 11-2 of the feeder 11, wheat leaves, barley, awns, dust and other smaller and lighter substances that cannot be used as papermaking...

Abstract

This invention discloses a gas mixing burst paper making method, in addition to a device. The method comprises the following steps: a) straw-rope spinning by the straw-rope spinning machine; b) removing the heavy war by the air-separator; c) removing the lightweight war and dust by the ash separator; d) boiling by the boiler, introducing the steam in the boiler to other boiler to use again; e) filling pressed air to the boiler after introduced steam and bursting to make slurry. The process can decrease the pollution to environment; in addition, it can increase the comprehensive utilization ratio of raw material.

Description

technical field [0001] The invention relates to a pulp preparation method and equipment in the papermaking industry, and is especially suitable for making pulp with wheat straw as raw material. Background technique [0002] my country's paper products are mainly made of non-wood pulp structure raw materials, most of which use wheat straw and waste paper as raw materials. The traditional lime method produces pulp, which produces a large amount of pollutants. These pollutants are difficult to treat, and the treatment costs are high. Cause losses and cause harm to the lives of the people. The traditional lime method and the blasting method currently used in papermaking cannot recycle the wheat grains, awns, and barley in the wheat straw, resulting in a large waste of resources. These substances enter the papermaking process and increase the pollution load. The high-pressure steam gas used in explosive papermaking is discharged into the atmosphere afte...
