Product Description

Product Description

The dryer cylinder for paper machine is a key part of paper drying, which is class I pressure vessel. The number of dryer cylinder accounts for about 2 / 3 of the total pressure vessels in the paper industry. Generally, the materials used for drying cylinder are HT200 and HT250

Spare Parts

The purpose of the turbulators is to destroy the condensation water ringformed in the dryer at high speed and generate more turbulence. The turbulators is installed on the inner surface of the dryer. It rotates with the dryer at the same speed, so it will move the water ring to produce turbulence, which is conducive to heat conduction.
 

In order to ensure the smooth discharge of condensed water in the dryer and avoid flooding; Make the cylinder surface temperature as high as possible to improve the drying efficiency; In order to reduce the temperature difference on the cylinder surface and make the moisture content of the paper uniform, the selection of siphon becomes the key.Dryer drainage siphon is basically divided into two forms: fixed type and rotary type.The fixed siphon is fixed on a certain point outside the dryer and does not rotate with the dryer; The rotary siphon is fixed in the dryer and rotates with the dryer.

Heat Transfer

The wet paper from the press section passes through a drying section consisting of a series of dryers. The steam heat in the dryer is transferred to the web through the cast iron shell, so that the web is heated and dried. The paper sheet is tightly covered by the drying fabric on the oven, so that the paper sheet can contact the surface of the oven better, thus strengthening the heat transfer process.
