Steam hydrophobization structure and method for steam tube nest rotary drier

Abstract

The invention relates to the technical field of rotary driers, and discloses a steam hydrophobization structure and method for a steam tube nest rotary drier. The steam hydrophobization structure adopted in the method comprises drier heat exchange pipes, circular ring pipes, connecting pipes, a steam separating package and a rotating joint. The rotating joint is communicated with one end of each connecting pipe in a sealed mode through the rotating steam separating package, wherein the connecting pipes are evenly distributed, and the other end of each connecting pipe is communicated with the corresponding circular ring pipe, wherein the circular ring pipes are radially evenly distributed. The circular ring pipes are communicated with the rotating drier heat exchange pipes. The circular ring pipes are provided with halving blocking plates on the connecting pipes which are circumferentially and evenly distributed. One end of an elbow arranged on the rotating steam separating package is arranged downward, and the other end of the elbow is connected with a condensate outlet pipe of the rotating joint. The steam hydrophobization structure and method can achieve the purposes of factory machining and manufacturing and field assembly of parts of the steam tube nest rotary drier, so that the difficulty in transportation, field installation and inspection is avoided. Large-scale manufacturing of the steam tube nest rotary drier is achieved, and the requirement for large handling capacity is met.

Description

technical field [0001] The invention relates to the technical field of rotary dryers, in particular to a steam drainage structure and method of a steam tube rotary dryer, which is suitable for the introduction of steam and the export of condensed water of the steam tube rotary dryer. Background technique [0002] The introduction of steam and the discharge of condensed water directly affect the efficiency of the dryer. In the traditional steam tube rotary dryer or steam calciner, a steam drum is designed at one end, and the steam heat exchange tubes in the dryer are all connected Steam drum, steam distribution and drainage by the steam drum. The connection between the steam heat exchange tube and the steam drum needs to be inspected by hydraulic test and other inspections, and these tasks are generally carried out in the factory. It is difficult to complete these tasks on site, that is, the complete machine manufacturing, overall transportation, and overall installa...
