Paper making equipment and soot blowing device

Abstract

The embodiment of the invention provides a soot blowing device for paper making equipment. The paper making equipment comprises a paper guiding roller and a paper web. The paper web is arranged on the paper guiding roller. The soot blowing device is arranged above and / or below the paper web for blowing the paper web so as to remove soot on the surface of the paper web; the soot blowing device comprises a soot blowing pipe and a gas source connected to the soot blowing pipe; the soot blowing pipe comprises a first pipe section and a second pipe section; the first pipe section is provided with a plurality of first exhaust holes which are separated at a preset distance; the second pipe section is provided with a plurality of second exhaust holes which are separated at a preset distance; gas blown from the first exhaust holes blows soot to a first edge and gas blown from the second exhaust holes blows soot to a second edge. The invention also provides the paper making equipment. In this way, the paper making equipment and the soot blowing device thereof provided by the embodiment of the invention can remove soot on the surface of paper before the paper is processed, so that the integral texture of the paper is improved, the cleaning and maintaining frequency of the equipment is reduced, and the soot removal efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of papermaking technology, and in particular relates to papermaking equipment and a soot blowing device thereof. Background technique [0002] During the paper processing process, paper dust is often attached to the paper, and the paper dust is easy to drop or fly from the paper. Paper ash mainly comes from the following sources: fillers are rarely added in the production process of household paper, so paper fine fibers tend to fall off and form paper ash; during the paper making process, fibers will go through the process of refining, and refining can Separating the fiber surface to increase the bonding force between fibers, and at the same time refining will inevitably produce fiber fragments, which are also the main source of paper ash; Paper dust is also likely to be generated after friction with rollers, cutters, guide plates and other equipment during rewinding and cutting. [0003] If the paper dust...
