Embodiment Construction

[0039] The technical solution of the present invention will be described in detail below in combination with the embodiments and the accompanying drawings.

[0040]The whole paper deinking method based on biological enzyme deinking of the present invention, its flow chart sees figure 1 , including the following steps:

[0041] Step 1. Flatten and fix the waste paper so that the side to be deinked faces up;

[0042] Step 2. Spray or smear the biological enzyme deinking solution on the side to be deinked, and wait for a certain reaction time;

[0043] Step 3. Use an adhesive device to stick to the side of the waste paper to be deinked, so as to remove the liquid and / or impurities containing toner after deinking, and complete the deinking.

[0044] In order to make the paper after deinking can be used directly, the following steps can also be included:

[0045] Step 4, heating the deinked waste paper to evaporate the liquid on it to obtain deinked usable paper.

[0046] In or...

Abstract

The invention relates to a deinking technology. The invention aims to provide a whole paper deinking method and device based on bio-enzyme deinking, which can solve the problem that the existing equipment for deinking by adopting a bio-enzyme method cannot be applied to scenes such as office areas and / or schools and / or families, and the technical scheme can be summarized as follows: firstly, flattening and fixing waste paper, so that the to-be-deinked surface of the waste paper is upward; spraying or smearing a bio-enzyme deinking solution on the surface to be deinked, and waiting for a certain reaction time; finally, a viscous device is used for being attached to the face, to be deinked, of the waste paper so as to remove the liquid containing the carbon powder and / or impurities after deinking in a sticking mode, and deinking is completed. The method has the advantages of being easy to implement, low in cost and suitable for whole paper deinking.

Description

technical field [0001] The invention relates to deinking technology, in particular to a whole paper deinking method and device based on biological enzyme deinking. Background technique [0002] The pulp and paper industry is one of the largest industries on earth. About 50% of the world's industrial logging is now used to make paper. It is estimated that papermaking consumes 18 million acres of forest every year, which is equivalent to 20 football fields every minute. Massive deforestation of trees and industrial emissions pose serious environmental challenges. At present, the paper industry has begun to actively promote the utilization of waste paper. Waste paper is one of the important renewable resources. Waste paper is recycled into paper mills and then produced into pulp. However, such a way of reusing resources does not solve all problems, the reason for which is the recycling system. Today, the global average recycling rate of printing and writing paper is only 8%...
