概述 Overview
SJL双联甲醇滤器、DJL单联甲醇滤器用于甲醇介质的过滤，以及其他类似特性的介质。
其中SJL双联甲醇滤器具有当压差达到规定值时，可不停机转换到另一个工作腔，使甲醇介质顺利过滤的特点。双联甲醇滤器转换阀是带双重截断与排放功能的，在转换阀切换过滤腔后能够起到双重截止的效果，防止渗漏。
SJL双联甲醇滤器、DJL单联甲醇滤器在停机状态下，具备对滤腔内的甲醇介质通过氮气置换的方式，将滤腔内部达到无害化状态的功能，实现安全排放、维护。
SJL Double-cylinder Methanol Filter & DJL Single-cylinder Methanol Filter are used for filtering methanol, as well as other media with similar characteristics.
When the pressure drop has reached the prescribed value, SJL double-cylinder methanol filter can convert to another chamber without stopping, making methanol filtered smoothly. The changeover valve is equipped with double block-and-bleed function, which can achieve double block and prevent leakage.
When the SJL & DJL methanol filter are shut down, they have the function of replacing the methanol in the filter chamber with nitrogen, making the inside of the filter chamber harmless and achieving safe emission maintenance.
