Technical field

The present application relates to the technical field of tobacco sheet production, and in particular to a water vapor separation device and tobacco sheet conveying system.

Background technique

In the production process of paper-making tobacco sheets, dust removal and extraction are the first steps. The tobacco raw materials are usually pumped into the material conveying pipe through a centrifugal fan. When passing through the dropper, the tobacco raw materials and dust are separated, and the tobacco raw materials enter the extraction tank. The body performs extraction operation, and the dust enters the dust removal system for collection and processing. Since the extraction liquid in the extraction tank is high-temperature hot water, during the operation of the centrifugal fan, water vapor will enter the dust removal system along the pipes, causing blockage of the dust removal pipes and equipment.

The current method to prevent water vapor from entering the dust removal system is usually to set a stop valve on the pipe between the dropper and the extraction tank. It is strictly forbidden to open the valve before the tobacco raw materials are transported, and the valve is closed immediately after the tobacco raw materials are transported. However, during the transportation of tobacco raw materials, part of the water vapor will still enter the dust removal system along the pipeline, so this approach cannot achieve good results.
