Humidifying device and fiber body processing apparatus

Abstract

A humidifying device includes a circulation path through which air circulates, an intake section that is provided in the circulation path and takes the air into the circulation path, a blower section that is provided in the circulation path and generates an air flow in the circulation path, a humidifying section that is provided in the circulation path and humidifies the air in the circulation path, and a discharge section that is provided in the circulation path and discharges the humidified air which is humidified by the humidifying section from an inside of the circulation path, and the circulation path has a pipeline for returning the humidified air that has not been discharged from the discharge section upstream of the blower section.

What is claimed is: 
     
         1 . A humidifying device comprising:
 a circulation path through which air circulates;   an intake section that is provided in the circulation path and takes the air into the circulation path;   a blower section that is provided in the circulation path and generates an air flow in the circulation path;   a humidifying section that is provided in the circulation path and humidifies the air in the circulation path; and   a discharge section that is provided in the circulation path and discharges the humidified air which is humidified by the humidifying section from an inside of the circulation path, wherein   the circulation path has a pipeline for returning the humidified air that was not discharged from the discharge section upstream of the blower section.   
     
     
         2 . The humidifying device according to  claim 1 , wherein
 the pipeline has a communication port that communicates with outside air.   
     
     
         3 . The humidifying device according to  claim 2 , further comprising:
 a valve provided at the communication port and configured to adjust an opening degree.   
     
     
         4 . The humidifying device according to  claim 1 , further comprising:
 a humidity detection section that detects a humidity of the humidified air passing through the humidifying section; and   a controller that controls an operation of the blower section based on a detection result of the humidity detection section.   
     
     
         5 . The humidifying device according to  claim 1 , wherein
 the humidifying section has a container filled with water and a water-containing body which is rotatably provided in the container and is partially immersed in the water.   
     
     
         6 . The humidifying device according to  claim 1 , further comprising:
 a heating section that heats the pipeline.   
     
     
         7 . A fiber body processing apparatus comprising:
 a processing section that processes fibers; and   the humidifying device according to  claim 1 , which humidifies the processing section.   
     
     
         8 . The fiber body processing apparatus according to  claim 7 , wherein
 the processing section is a separation section that separates foreign matter from a defibrated material obtained by defibrating a material containing fibers, and   the humidifying device humidifies the separation section.
