Moisture collection device in paper machine wire section

Abstract

The invention discloses a water vapor collecting device of a net part of a paper machine. The water vapor collecting device of the net part of the paper machine comprises a box body; a suction chamberis arranged in the box body; a suction inlet is arranged in the side part of the box body along the length direction of the box body; a plurality of suction pipe openings are arranged at the top of the box body along the length direction of the box body; each suction pipe opening is connected with one vacuum fan through one pipeline for forming a suction air flow which is conveyed to the vacuum fan through the suction inlet, the suction chamber, the suction pipe opening and the pipeline; a water vapor separation device is arranged between each vacuum fan and the box body and used for carryingout vapor separation on the suction air flow; and a heating device is arranged at the outer side of the bottom of the box body and used for heating the box body. According to the water vapor collecting device provided by the invention, a vacuum suction type design is adopted, the starch granules, slurry particles, water mists and the like which scatter around can be actively sucked, so that the problem of pulp dropping which frequently occurs on a water receiving pan can be reduced, and the running state of a paper machine device and the product quality are improved.

Description

technical field [0001] The invention relates to the field of paper machines, in particular to a water vapor collection device for the wire part of a paper machine. Background technique [0002] In the area where the other layers of the wire part of the multi-layer fourdrinier paper machine are combined with the bottom layer of the fourdrinier wire, the running direction and state of each layer of wire cloth running at high speed are different. Driven by the various layers of mesh cloth, the operation is extremely disordered. In addition, two or more starch spray pipes are equipped in this area to spray starch on the surface of the pulp layer before compounding when making specific paper types, so as to improve the interlayer bonding force, stiffness, offset printing performance and other characteristics of the cardboard. . The raw material of spray starch used in papermaking is industrial starch, which will gelatinize at 60-70°C. When the paper machine is running at a hig...
