[specific embodiment]
Below by drawings and examples, the technical solution of the utility model is described in further detail.
The utility model provides a kind of filter device for purifier back segment, as shown in Figure 1, including going out with purifier
The main line filter 2 of mouth pipeline connection, the export pipeline of main line filter 2 are connected to plate heat exchanger 9, main line filter 2
Inlet end and an outlet end is respectively arranged with valve A1 and valve B2；Main line filter 2 includes hollow shell and is installed in it
The filter cylinder 10 of taper, filter cylinder 10 is made of strainer and its input end of opening towards main line filter 2, the strainer diameter of filter cylinder 10
Less than the particle diameter of molecular sieve.Filter cylinder 10 is because tapered structure effectively stops particle while not generating using tapered structure
The characteristics of extra resistance does not influence air into pressure tower, is less than sieve particle diameter using the filter opening of filter cylinder 10, reaches resistance
Gear sieve particle enters the effect of plate heat exchanger 9.Under normal conditions, the diameter of strainer is 105 μm~147 μm.
In addition, can also be arranged in parallel by-pass filter 5 by main line filter 2, the arrival end of by-pass filter 5 is provided with
Valve C4, and it is connected to the export pipeline of purifier；The outlet end of by-pass filter 5 is provided with valve D6, and is connected to board-like
The inlet ductwork of heat exchanger 9；By-pass filter 5 includes the filter cylinder 10 of hollow shell and the taper being installed in it, filter cylinder 10 by
The input end that strainer is made and it is open towards by-pass filter 5, the strainer diameter of filter cylinder 10 are less than the particle diameter of molecular sieve.
The shell of main line filter 2 is connected with valve E, valve E be used for into shell purge gas with to enclosure interior into
Row cleaning.The shell of by-pass filter 5 is connected with valve F, and valve F is used for into shell purge gas to carry out to enclosure interior
Cleaning.In use, can switch periodically according to the resistance of place pipeline using main line filter 2 or using by-pass filter 5
Be filtered, and it is corresponding blowback is carried out to main line filter 2 or by-pass filter 5 using valve E or valve F, do not need to stop
Vehicle purging.When to main line 2 blowback of filter, gas is entered by valve B and is taken impurity out of from valve E；It is anti-to by-pass filter 5
When blowing, gas is entered by valve D and is taken impurity out of from valve F.
Purifier includes No. 1 purifier and No. 2 purifiers being set side by side and independently working alternatively, No. 1 purifier and 2
The gas exit line of number purifier is connected to main line filter 2.The gas exit line of No. 1 purifier and No. 2 purifiers
It is connected to by-pass filter 5.
The working process of the utility model is as follows:
Step 1: entering from the gas that purifier flows out from valve A, and flows out through main line filter 2 and valve B, then into
Enter plate heat exchanger 9；
Step 2: after the resistance of 2 place pipeline of main line filter rises, then valve C and valve D are opened, and close valve
Door A, i.e. switching use by-pass filter 5；
Step 3: Open valve E carries out blowback to main line filter 2, and when blowback, gas is entered by valve B and by impurity
It is taken out of from valve E；
Step 4: after blowback, valve B and valve E is closed.
By-pass filter 5 switches to the method for main line filter 2 similarly.
When normal driving, if needing to open valve B and valve A in advance with main line filter 2, remaining valve is closed；If with
By-pass filter 5 needs to open valve C and valve D in advance, remaining valve is closed；
The filter device for purifier back segment of the utility model avoids the particulate matter of molecular sieve by setting filter
Into plate heat exchanger, reduce the equipment loss of plate heat exchanger, and improve heat transfer effect, increases space division system product
Efficiency.
Before the transformation for not carrying out the utility model, if more transducer set plate heat exchanger, the primary purging that stops needs
It stops production 5 days, 200 Yu Wanyuan of economic impact, along with the various costs for taking off sand sand loading, economic impact may be up to 500 Yu Wanyuan,
And after carrying out the transformation of the utility model, reduce the number of parking purging plate heat exchanger, improve production capacity for enterprise, drops
Low cost.
The above content is only to illustrate the technical idea of the utility model, and the protection model of the utility model cannot be limited with this
Enclose, it is all according to the utility model proposes technical idea, any changes made on the basis of the technical scheme each falls within this reality
Within protection scope with novel claims.
