Ultrasonic humidifying device of paper machine

Abstract

The invention relates to an ultrasonic humidifying device of a paper machine. The device comprises a water tank (1) and at least one long pipe (2) which are connected through a pipeline, a water inletpipe is arranged on the side surface of the water tank (1), clear water (13) and at least one ultrasonic atomizer (12) for oscillating the clear water (13) to generate atomized water vapor (14) are arranged in the water tank (1), the ultrasonic atomizer (12) is arranged on the bottom surface of the water tank (1), the clear water (13) is positioned in the water tank (1), and at least one air outlet (21) is formed in the long pipe (2). Compared with like devices in the prior art, the device of the invention has the advantages of convenience in installation, low consumption, wide application range and the like.

Description

technical field [0001] The invention relates to the field of paper production, in particular to an ultrasonic humidifying device for a paper machine. Background technique [0002] Household paper is also called tissue paper. Due to its low basis weight, usually 11.5 grams to 22 grams, it is dried in a single Yankee dryer, and then undergoes a special creping process; during this period, it is easy to produce paper dust. , causing paper dust to fly in the workshop. At this time, it is necessary to humidify the paper machine to avoid this situation; [0003] For example, although the BF paper machine in Kawanoe, Japan has a good forming effect, the difference between the two sides of the base paper is obvious, and delamination is easy to occur during the slitting and rewinding process, resulting in poor processing and use effects. Dripping water will cause quality problems. During the drying process of the base paper, the air pressure will be increased to form an overdrying p...

Problems solved by technology

[0003] For example, although the BF paper machine in Kawanoe, Japan has a good forming effect, the difference between the two sides of the base paper is obvious, and delamination is easy to occur during the slitting and rewinding process, resulting in poor processing and use effects. Dripping water will cause quality problems. During the drying process of the base paper, the air pressure will be increased to form an over-drying phenomenon, resulting in a slightly lower moisture content of the base paper, which is 5-9% lower than the national standard moisture, resulting in static electricity and poor hand feeling on the base paper.
