Drying cylinder condensate water draining device

Abstract

The invention relates to a drying cylinder condensate water draining device. The drying cylinder condensate water draining device comprises a draining pipe installed in a drying cylinder, one end of the draining pipe extends out of the drying cylinder, multiple separators are installed on the draining pipe, an inlet of each separator is connected with a winnowing pan, and an outlet of each separator is communicated with the draining pipe. By means of the winnowing pans, condensate water in the drying cylinder carries part of steam to rush into the separators, the condensate water and the steam are separated through the separators, the steam returns into the drying cylinder, only the condensate water enters the draining pipe under the action of gravity, in this way, the stable flowing state in the draining pipe is kept, and the condensate water can be conveniently drained in time. The condensate water draining device is particularly suitable for draining condensate water in medium-and-high-speed paper making machines.

Description

【Technical field】 [0001] The invention relates to the field of condensed water discharge, in particular to a drying cylinder condensed water discharge device. 【Background technique】 [0002] At present, the use of water vapor phase change in the rotating cylinder to release heat, and the external surface of the cylinder to heat the material is widely used. This kind of heating device has difficulty in discharging condensed water. In order to overcome this difficulty, people have made various efforts, especially in the pulp and paper industry. In order to improve the drying efficiency of the paper machine, the condensed water in the drying cylinder must be discharged in time. People adopt structures such as spiral grooves, spoiler rods, and rotating siphons in the drying cylinder, but the effect still cannot meet the requirements of industrial production. The reason is that none of the above measures can improve the state of unstable vapor-liquid two-phase flow in the drying ...
