Description
Technical field
The present invention relates to the design of the structure of on-line sampling device, in particular to one kind has heat insulation effect and can be in continuous
Acquire and store the on-line sampling system of multiple detection samples.
Background technique
In the practical operation of catalyst test apparatus, need to carry out reactor product the on-line sampling under stable condition
And qualitative analysis, the sampling process of sample should not influence the operation of reactor assembly, such as the fluctuation of pressure.After acquiring simultaneously
Sample needs are sent directly into chromatography by carrier gas and are analyzed, to obtain the component part of sample.In order to ensure the sample of acquisition has
It is representative and noiseless to current system, acquisition cross range request quickly, conditional stability.
If Figure 1A, 1B show the first, second status diagram that traditional on-line sampling is installed in sampling process,
Line sampling apparatus includes one 6 mouthfuls 2 valves A, a pipeline loop.The both ends of pipeline loop be connected to valve A port 5,
6.In first state, the connection of port 1,6, the connection of port 2,5 and the port 3,4 of valve A is connected to, and reaction product L passes through the port of valve A
1 enters and is transmitted to pipeline loop, until reaction product L is discharged full of pipeline loop and through port 2, carrier gas F passes through the port valve A
3, enter analyzer after 4；In the second state, switching valve A is connected to the port 3,5 of valve A, 4,6 are connected to and 1,2 connections, carrier gas F
Product in loop pipeline B is sent into analyzer by the port 3,4 through valve A.To which on-line sampling device 1 is in the first, second state
Between constantly switch, reaction product L is then timed acquisition and is sent into analyzer and analyzed in time.
However, on the one hand, not any Insulation of traditional on-line sampling device 1, when reaction product is easily poly-
When the product for closing and cracking, it will result in pipeline blockage in a short time, need manually to clean sample lines and valve road.Although working as
It is preceding when analyzing the product for being also easy to produce polymerization, heat preservation sampling bottle can be used and sampled offline, then by operator general
Sample input analyzer is analyzed, and avoids the cleaning to valve body and pipeline with this, but this offline sampling needs artificial behaviour
Make, increase human cost, and keep the temperature sampling bottle there is no accurate temperature controlling, be easy to make reaction product reach the temperature easily polymerizeing and
Sampling valve in analyzer is caused to block.
In on the other hand, in certain reaction systems, the deactivation time of catalyst is very short, may there was only 10 minutes.This
When for the product component situation of change in 10 minutes, need to carry out multiple repairing weld (such as 1 minute sampling primary) in a short time.
Restriction of the above-mentioned sample collection method by the chromatography time, is unable to satisfy the short time, and the timely analysis of multiple samples is wanted
It asks.If certain needs complete the above work, it is necessary to which setting is more than one or more analyzer to complete this work.Due to
Analyzer is expensive, will cause greatly improving for experimental cost.
Summary of the invention
The purpose of the present invention is to provide a kind of on-line sampling systems, so that on-line sampling system carries out under constant temperature

After the completion of 8 detection sample collections, control device 14 controls import modul 11 and switches simultaneously with export module 12
To exported schema.In exported schema, imports valve A and gate alternate path T2 and fourth passage T4 simultaneously, sluice valve B is successively gated and deposited
It stores up pipeline loopi (i=1,2,3,8), wherein sluice valve B will stop preset duration after gating a storage pipeline, then select again
Lead to next storage pipeline；Delivery valve C opens the first delivery outlet C2And simultaneously close off the second delivery outlet C3.To which carrier gas air is logical
The alternate path T2 for crossing importing valve A enters sluice valve B, and carrier gas air sequentially enters each item by sluice valve B and stores pipeline to push
The detection sample being stored in storage pipeline passes through the first delivery outlet C of delivery valve C2Into detector 3.In addition, reaction product L
It can be directly entered exhaust gas processing device 14 by importing the fourth passage T4 of valve A, i.e., there are also reaction product L from anti-immediately at this time
It answers in container and exports, also do not pollute the environment.
By upper analysis it is found that import valve A, sluice valve B, delivery valve C can cooperate, with out of reaction vessel 2 successively
Multiple detection samples are acquired, and multiple detection samples will be stored respectively in a plurality of storage pipeline；After the completion of acquisition, in carrier gas
Under the cooperation of device F, then those detection samples are sequentially output to detector 3 and are detected.To, overcome in tradition due to
The limitation of each detection time of detector and in online acquisition in the short time and the limitations of multiple samples can not be analyzed.Meanwhile by
It is all set in incubator 10 in importing valve A, sluice valve B, delivery valve C, therefore on-line sampling system 1 can be under steady temperature
Multiple detection samples are acquired and stored, prevent reaction product from causing to block connecting tube due to the too low generation fission of temperature or fusion
Road and valve body internal passage.It is set it is worth noting that importing valve A, delivery valve C and passing through connecting pipe (not shown) respectively and be connected to
Reaction vessel 2, the detector 3 set outside incubator 10 can also be in connecting pipes in order to reach further heat insulation effect
Heat-insulation unit is arranged in part outside incubator.The heat-insulation unit is, for example, one layer of heat preservation cotton；Alternatively, the heat-insulation unit may be used also
Think an individual temperature conditioning unit (such as comprising temperature detector, heater, controller etc.).
Second embodiment of the present invention is related to a kind of on-line sampling system.Second embodiment is big with first embodiment
Cause identical, be in place of the main distinction: in second embodiment of the invention, the number of reaction vessel be it is multiple, as shown in Figure 4
For 5 reaction vessels 2, however present embodiment is not intended to be limited in any this, and those skilled in the art can be according to actual needs
The number of reaction vessel is set.Acquisition unit 101 includes also container selector valve D, is connected to control device 13.Container selector valve D
It is essentially one valve of multiselect, is in present embodiment, container selector valve D selects 1 valve for 5, has 5 input port DinWith 1
A delivery outlet Dout, 5 input port D of container selector valve DinIt is connected to 5 reaction vessels 2, the output of container selector valve D
Mouth DoutIt is connected to the first communication port A for importing valve A1.Control device 13 is selected by control container selector valve D from one of them
Reaction vessel 2 is sampled.Exist to which on-line sampling system 1 that, present embodiment provides can be realized to multiple reaction vessels
Line sampling.
It is noted that each module involved in present embodiment is logic module, and in practical applications, one
A logic unit can be a physical unit, be also possible to a part of a physical unit, can also be with multiple physics lists
The combination of member is realized.In addition, in order to protrude innovative part of the invention, it will not be with solution institute of the present invention in present embodiment
The technical issues of proposition, the less close unit of relationship introduced, but this does not indicate that there is no other single in present embodiment
Member.
