Description
Technical Field
The disclosure relates to the technical field of detection, in particular to a device for performing offline reactivation on a molecular sieve.
Background
Ion Mobility Spectrometry (IMS) is widely used in security inspection of airports, subways, and venues as a technology for rapidly detecting explosives, drugs, and chemical warfare agents. The existing ion migration technology generally uses dry air as a carrier gas of a migration tube, so that the space can be saved, and the instrument can be conveniently designed into a portable desktop or a desktop with small volume. Air is taken as a carrier gas source, the air is pumped into a gas path through an air pump, water vapor is filtered through a molecular sieve to form dry air, the dry air enters a migration pipe through shunting to serve as carrier gas and blowing gas, and each path of air flow in the migration pipe finally leaves the migration pipe from an outlet. There are also devices that use the device to be dewatered before the molecular sieve to increase the useful life of the individual molecular sieves. There are also combinations of activated carbon in the molecular sieve to remove residual organic gases. The molecular sieve used by the current ion migration equipment is divided into two types: periodically replaced molecular sieves, or molecular sieves with regeneration function. Most of equipment uses the periodically replaced molecular sieve, and the molecular sieve loses efficacy after the water vapor of the molecular sieve is saturated, and at the moment, the equipment needs to be replaced, so that the equipment can normally work, and the lost molecular sieve is discarded. The periodic replacement of the molecular sieve is the most traditional technology, the method is simple, but the filter material of the instrument needs to be replaced at regular time, the shortest replacement period is less than one month according to the use frequency of a user and the pollution condition of equipment, and the defect is that: additional work is brought to the user, additional training is required, and the cost of use and maintenance is increased due to the high price of the filter material. Its advantages are no failure (or pollution), easy replacement of filter material, and short cleaning period. The renewable molecular sieve has the advantages that the molecular sieve does not need to be replaced, convenience is brought to the use of customers, and meanwhile, the maintenance cost is reduced. The disadvantage is that the source of contamination cannot be cut off in time, and when contamination occurs, the instrument needs to be cleaned for a long time.
