Description

  The present invention is used as a large-sized compressed air dehumidifying device, and in particular, a large-sized demister device equipped with a multi-product demister device that can be transported easily and can be installed in an installation environment by modularizing and stacking the demister devices. The present invention relates to a capacity compressed air dehumidifier.

  Large-scale dehumidifiers are required for large-scale dehumidification of large plants. This dehumidifier is equipped with a demister device used as a gas-liquid separator for separating moisture and the like generated when the compressed air is cooled from the compressed air. However, if the demister device is too large, it will be difficult to carry it out from the production site to the usage site. In other words, the dehumidifying device is usually transported by a truck, but there is a limitation on the loading capacity of the truck and the width and length of the loading platform. When the demister device has a large size, there is a disadvantage that transportation becomes difficult.

  On the other hand, the present inventor has previously proposed a demister device for compressed air dehumidification that does not require a large installation space according to Patent Document 1. According to this demister device, a plurality of demisters are formed in the inner cylinder to separate gas and liquid at intervals, and a drain pan for receiving the liquid separated by the upper demister is installed between the demisters. At the same time, the compressed air that has passed through the lower demister in the drain pan is disposed so as to prevent re-passage to the upper demister.
