Column deluge suppression system

摘要

A column deluge suppression system for suppressing a hazard occurring in a grain dryer includes a plurality of vertical column sections and a segmented, annular manifold. The manifold is positioned around the upper section of the grain dryer in proximity to the grain columns. The manifold includes a plurality of elongated deluge drops that extend toward the grain column openings and permit water to drench the grain columns.

主权项

1. A column deluge suppression system for a grain dryer, the system comprising:
an inlet in fluid communication with a drainage elbow; at least one vertical column section in fluid communication with the drainage elbow and extending along an exterior of a grain dryer; a starter section in fluid communication with the at least one vertical column section and extending from the exterior of the grain dryer to the interior of the grain dryer at a location proximate the top of the grain dryer; a column deluge manifold in fluid communication with the starter section, the column deluge manifold having a plurality of elongated deluge drops that are in fluid communication with a plurality of grain columns in the grain dryer; wherein the column deluge manifold includes a plurality of horizontal sections assembled together with the starter section such that the column deluge manifold forms an annular, segmented column deluge manifold; wherein each of the starter section and the plurality of horizontal sections has three deluge drops positioned over each of the plurality of grain columns; wherein the starter section has a drop inlet elbow; and wherein one of the deluge drops extends from the drop inlet elbow.
