The invention discloses a cryogenic liquid tank car or tank box molecular sieve device and a molecular sieve filling method thereof. The molecular sieve device comprises a process manhole device, wherein the process manhole device is a barrel column welded to an inner tank end socket of a cryogenic liquid tank car or tank box, a lower opening of the barrel column is provided with an elliptical head in a matched and welded mode to form the device which is provided with an upper opening and used for containing a molecular sieve, the upper opening communicates with an interlayer formed between anouter tank of the cryogenic liquid tank car or tank box and the inner tank of the cryogenic liquid tank car or tank box, a circular cover plate is welded on the upper opening, a filter screen capableof preventing the molecular sieve from leaking into the interlayer is pressed on the circular cover plate, a suction nozzle is further mounted on the circular cover plate, and a screw cap is hermetically mounted in a nozzle opening of the suction nozzle. The molecular sieve filling method of the molecular sieve device is simple to operate, and the adsorption performance of the molecular sieve cannot be reduced due to adsorption of moisture in external air during filling, so that the molecular sieve can be guaranteed to be in the optimal adsorption state.

    本发明公开了低温液体槽车或罐箱分子筛装置及其分子筛的充装方法。分子筛装置包括工艺人孔装置,工艺人孔装置为焊装在低温液体槽车或罐箱的内罐封头上的桶柱体,桶柱体的下端口配装焊接上椭圆形封头后构成了具有上开口的用于盛装分子筛的装置,上开口与低温液体槽车或罐箱的外罐和低温液体槽车或罐箱的内罐间形成的夹层相连通,该上开口上焊装有圆形盖板,圆形盖板上压装有能防止分子筛漏进夹层的过滤网,圆形盖板还上安装有吸嘴,吸嘴的嘴口中密封安装有旋盖。该分子筛装置的分子筛充装方法操作简单,使分子筛不会在充装时因吸附外界空气中的水分而降低吸附性能,从而保证分子筛能处于最佳的吸附状态。
