蒸压釜在运行时,釜内壁和制品坯体表面都将析出大量的冷凝水,使蒸压釜上、下温差过大,导致釜底部产生很大的拉伸应力。为此,设计制造部门在釜体上配置了冷凝水的排放装置。但这种装置只能疏排冷凝水,不能清除釜中的颗粒污物。然而,这种污物却会给釜体造成腐蚀,又不利于冷凝水的疏排。而且在釜中堆积时间过长时,要清除这样的硬块势必损伤釜壁的氧化保护膜,更加剧了釜的腐蚀。贯通式蒸压釜多是进料、出料同时在两 When the autoclave is in operation, a large amount of condensed water will be precipitated on the inner wall of the kettle and the surface of the product body, so that the temperature difference between the upper and lower sides of the autoclave is too large, resulting in a large tensile stress at the bottom of the kettle. For this purpose, the design and manufacturing department is equipped with a condensate discharge device on the kettle body. However, this device can only drain the condensate, and it cannot remove the particulate dirt from the still. However, this dirt will cause corrosion to the kettle body, and it is not conducive to the drainage of condensed water. Moreover, when the accumulation time in the kettle is too long, removing such a lump will inevitably damage the oxidation protective film on the wall of the kettle, further exacerbating the corrosion of the kettle. Through-type autoclaves mostly feed and discharge at the same time in two
