Embodiment Construction

[0030] The following description is merely exemplary in nature and not intended to limit the disclosure, application or use.

[0031] Such as figure 1 , figure 2 As shown, the anhydrous pulping and expanding device of the present invention includes a film washing machine 2, a thread rolling machine 10, a screw dehydrator 3, a reaction chamber 30 and a high-consistency refining machine 6, and raw materials are sent into the film washing machine through a belt 1 2 for cleaning, and the raw materials from the film processor 2 are processed into pulp after dehydration, thread rolling, reaction, and refining. A puffing device 20 is provided between the thread rolling machine 10 and the reaction chamber 30 . In the anhydrous pulping and expanding device, a set of expanding device is added after the thread rolling machine in the existing pulping process. The expanding mechanism is to press the coarsely rubbed pulp into the sealed tank, and then inject oxygen and steam into the tank...

Abstract

The invention relates to an anhydrous pulping and puffing device, adopting the oxygen alkali puffing mode to obtain the energy-saving and water-saving clean pulping process without discharge of the waste water, waste gas and waste residue, the oxygen alkali puffing and pulping method adopts the combination mode of the oxygen alkali process and puffing process for dissociating the fiber, the weak mechanical treatment mode is adopted for guaranteeing the fiber strength, reducing the energy consumption and realizing high pulping yield; a set of puffing device is arranged behind the thread rolling machine of the existing preparation device and used for pressing the coarse sizing agent into the sealed tank, the sizing agent can be discharged during a short time and transported to the puffing reaction cabin for having reaction continuously, the fiber can be fast separated and easily lancinated by adopting the improved process and the production efficiency is raised.

Description

technical field [0001] The invention relates to an energy-saving, water-saving and clean pulping device that adopts an oxygen-alkali expansion method to obtain an energy-saving, water-saving and clean pulping device without discharge of waste water, waste gas and waste residue, in particular to a waterless pulping device. Background technique [0002] Pulping is the process of separating fibers from plant fibers to obtain pulp. Pulping methods are mainly divided into mechanical method, chemical method and chemical mechanical method, and mechanical pulp, chemical pulp and chemical mechanical pulp are obtained respectively. In the prior art, due to the difficulty of controlling the magnitude of the force, the filaments are insufficient or the fibers are damaged; and the strong mechanical friction will directly convert a large amount of mechanical energy into heat energy, which greatly increases the power consumption; secondly, the huge axial force makes the equipment The cost...
