A kind of multi-
tower joint analytical gas purification device, belong to
raw material gas purification equipment related technical field, including adsorption
tower, packing is filled in adsorption
tower, for the
impurity in
raw material gas is adsorbed and purified, adsorption tower is provided with multiple, all adsorption towers are in
parallel arrangement;In all adsorption towers, at least one adsorption tower is in analytical working state, at least two adsorption towers are in adsorption working state.Multiple
layers of packing are arranged in the adsorption tower and are arranged according to the adsorption order, packing aperture, adsorption strength, analytical condition, multiple different packings are filled separately, and then are filled together in the adsorption tower, the packing
layers are isolated.The utility model adopts sealing layer filling, and the packing
layers use special sealing separation components, ensure that the packing is not mixed, and it is simple and fast to replace a layer of packing, the utility model is put into use, and the
pressure swing adsorption purification device is significantly reduced after one year attenuation rate.
