Abstract

The invention discloses a paper product filler pretreatment device and process. The treatment device comprises a screw rod pump, a homogenizer, a material conveying pump, a metering tank, a microwavereactor, a main reactor, an energy transduction system, a decompressor, a dehydrator, a backflow water tank and a backflow water pump. The pretreatment process comprises the following steps: feeding araw filler into the homogenizer through a pipeline, adding a part of a high-temperature circulation liquid into the homogenizer, carrying out homogenization and heating, and conveying the mixed raw filler into the microwave reactor through the material conveying pump; feeding a middle filler pretreated by using the microwave reactor into the main reactor through a pipeline; carrying out secondarycirculation liquid mixing heating and auxiliary heating on the middle filler in the main reactor, and carrying out a thermal chemical reaction; in the energy transduction system, and effectively exchanging heat of a filler solution treated after the thermal chemical reaction in the main reactor to circulated water. By adopting a paper product prepared from the filler, a great amount of plant fiber resources can be saved. Meanwhile, the plant fiber resources are saved, and the raw material cost of the paper product is also reduced.

Description

technical field [0001] The invention relates to the field of paper products, in particular to a pretreatment device and process for filling paper products. Background technique [0002] Paper products are widely used in all aspects of human life and production. With the in-depth application of paper products in the consumer field, the consumption of paper products is growing rapidly. Producing one ton of paper products requires 20 trees aged 20-40 years, and the recycling rate of waste paper fibers is relatively low. In the period of rapid decline of traditional forest resources and rapid industrial development, the emergence of a new material that replaces traditional paper fibers has great significance and application prospects. Contents of the invention [0003] In view of the above defects, the present invention proposes a pretreatment device and process for paper product fillers, so as to realize the reuse value of resources after the pretreatment of the soil and th...
