Library steel discharge system consists of gas pipelines, exhaust pipes, library gasification pipe, and a discharge passage of five parts.
   (1): gas pipeline steel library using standard DN50 galvanized steel pipe, gas main channel center gasification zone is introduced directly into the intake pipe wall outside the library, gas piping layout library side gasification zone In the library wall plate outside the library.
   (2): exhaust duct plate library using standard DN32 type seamless steel pipe, arranged in the same manner in the form of tubes and gasification, gasification of the exhaust pipes and distribution pipes combined.
   (3): Library Body gasification tube steel library using standard DN32-50 type of seamless steel tubes, steel pipe in the external layer of soft metal tube in the outer metal tube with a layer of soft rock cotton tube, the tube arrangement gasification by way of the reservoir bottom center fanned outward expansion, the distance is 50cm. Fan-shaped tube close to the library at the end gasification installed in parallel, it consisted of a number of different regional components.
   (4): Steel library discharge system, the most important is the library library gasification steel tube apparatus, its intake area is open to cross diagonally through the cycle gas distribution pipes by gasification center area outside the strip radiation distribution was arranged. Gasification steel pipes installed in the library from the library at the end of the passage, parallel to the ground from a distance of 20cm, it is the material sent by the pipe inlet hoist a certain gas pressure by help gas equipment. Regardless of distance can achieve a pass-through effect.
