Utility model people has found that the scheme of the prior art is difficult to reach preferable circular regeneration effect to cleanser, mainly
The reason is that being extraneous air heat regenerated input in the process, processing is not filtered to air, is easy to regenerate heating
Cleanser cause secondary pollution, to influence the regeneration effect of cleanser, and then influence purifier and the purification of gas imitated
Fruit.
According to this improved though, the utility model provides a kind of gas cleaning plant, in conjunction with shown in Fig. 1 and Fig. 2,
In one schematical embodiment, which includes the first purifying part 1, the second purifying part 5 and switching part,
Switching part can switch between the first state and a second state.Wherein, when switching part is in first state, first is net
Change component 1 and component to be clean forms gas purification loop, the first purifying part 1 is treated the air in purifying part and purified
Filtering removes impurity.When switching part is in the second state, it is (such as empty that the second purifying part 5 can suck external gas
Gas) and carry out purification filtering, and it is supplied to the first purifying part 1 to be used as regeneration gas purified gas, so as to the
When one purifying part 1 carries out circular regeneration, the aqueous vapor of the first purifying part 1 and impurity is promoted to flow outwardly, forms circular regeneration
Access.During carrying out circular regeneration to cleanser, gas purification loop is off.
For example, when gas cleaning plant is used for ionic migration spectrometer, component to be clean can be transference tube 4, letter
Claim IMS.When gas cleaning plant is used for the gas purification in Other Instruments, component to be clean can also be realization corresponding function
Component.Each embodiment given below for ionic migration spectrometer for illustrating.
The gas cleaning plant of the utility model embodiment can be prevented using filtered air as regeneration gas
Secondary pollution is caused during cleanser circular regeneration；And it can be by the state switching performance of switching part, in non-purification
Under state to cleanser carry out circular regeneration, may make purification and regeneration two kinds of working conditions mutually restrict, synchronization only
In a kind of specific working condition, i.e., regenerated without cleanser in the case where purifying working condition, in cleanser reproduction operation shape
Without purifying work under state, interfered with each other to avoid generation.Above-mentioned both sides advantage, which can improve, carries out cleanser
The reliability of circular regeneration, to optimize the performance and used life of gas cleaning plant.
Preferably, switching part is switching valve.Switched by the working position of switching valve, first state and the second state it
Between switch, can make gas cleaning plant it is convenient, it is reliable, rapidly work shape in purification working condition and cleanser circular regeneration
It is converted between state.And when switching valve is in first state, cleanser circular regeneration access disconnects, and switching valve is in the second shape
When state, gas purification loop disconnects, and is reliably prevented from two kinds of working conditions of purification and regeneration and mutually generates interference, optimizes gas
The performance of body purifier.Alternatively, switching part can also selective switchgear or it is other can pass through movement realize shape
The structural member etc. of state conversion.
Compared with the switching part for realizing state conversion by structural member, the switch valve structure of the application is simple, is easy to fill
Match, and progress break-make control is only needed to can be realized as the switching between two states, is not related to structural member movement travel
Control, control it is simple and reliable.
In a specific implementation, as shown in Figure 1, switching part includes the first switching valve 2 and the second switching valve 3.The
One switching valve 2 and the second switching valve 3 can be when all in first states (as shown in Figure 2), the first purifying part 1 and to be clean
Component forms gas purification loop.First switching valve 2 and the second switching valve 3 can be when all in the second states (such as Fig. 1 institutes
Show), the second purifying part 5 is that the first purifying part 1 provides regeneration gas by the second switching valve 3, in cleanser circular regeneration
During, promote aqueous vapor and impurity in the first purifying part 1 to be discharged by the first switching valve 2.In the second condition,
Second purifying part 5, the second switching valve 3, the first purifying part 1 and the first switching valve 2 are sequentially communicated to form cleanser cycle again
Raw access.
More preferably, the first switching valve 2 and the second switching valve 3 are two-bit triplet solenoid valve.
First switching valve 2 is exported between component to be clean for the first purifying part 1 of control or the first purifying part
1 outlet and external connected relation, the second switching valve 3 are used to control between 1 import of the first purifying part and component to be clean, or
The connected relation of person's the first purifying part 1 and the second purifying part 5.
The embodiment is used cooperatively by two independent switching valves, can be regenerated to cleanser, realizes Ion transfer
Cleanser inside spectrometer is non-maintaining；And internal gas pipeline flexible topology can be facilitated, reduce the volume of gas cleaning plant；
In addition gas cleaning plant can also be made conveniently, reliably, rapidly to purify working condition and cleanser circular regeneration work shape
It is converted between state.
Except through the mode that two independent electrical magnet valves are used cooperatively, a switching valve can also be used to realize, Neng Goujie
About space reduces the volume of gas cleaning plant.For example, in one embodiment, two switching valve designs are an integral structure,
But it is upper mutual indepedent in control.In another embodiment, switching valve is designed as twin-channel form, such as using electricity
When magnet valve, when by controlling same electromagnet, two channels can be made while being switched to first state, or switched simultaneously
For the second state, the reliability of gas cleaning plant working state control is improved, avoids making two to cut due to there is accidentally control
Change the unmatched situation of working condition of valve.
