Description
Technical field
The utility model is related to deduster leak hunting technology field, and in particular to a kind of on-line automatic leakage detection apparatus of deduster.
Background technology
During using sack cleaner, dozens of dust-removal cloth-bag is generally set, in dust removal process, dust removing cloth is often had
Bag leakage dust problem.At present can be using detection dust-removal cloth-bag inside and outside differential pressure or air-introduced machine and dust-removal cloth-bag after dust-removal cloth-bag
Between pipeline on detect that the mode of dust concentration hunt leak detecting whether leak-off pocket, when pressure difference or concentration are higher than setting value, table
Bright dust-removal cloth-bag has leaked, and dust effusion is exceeded, it is necessary to the dust-removal cloth-bag for more renewing.Because dust granules are trickle, current two kinds
Detection mode can only determine leakage and not leak, visually be difficult to observe and position the specific dust-removal cloth-bag for leaking dirt, i.e., not can determine that specific
Leak-off pocket position, if the complete dust-removal cloth-bag for more renewing, can be underused because not leaking cloth bag and caused by waste and be added to
This, is if be changed without, dust retention generation environment pollution not yet in effect, and cause effusion product to lose.
In order to detect specific leak-off pocket position, 02122331.9（On December 31st, 2003 is open）Disclose cloth bag certainly
Dynamic leakage detecting device, sampling nozzle is directed at every sack of cloth bag one by one in orbit with the rail wheel of swing arm, and deduster is external
High-pressure mini blower fan the gas sample of each cloth bag is extracted out, watch gas sample, just can find whether every cloth bag damaged；
200710015073.8（On November 28th, 2007 is open）Automatic leak-checking device for cloth bag is disclosed, by longitudinal stepping mechanism, horizontal stroke
To stepping mechanism and sampling mechanism, the linkage of these three mechanisms extracts gas sample from the sack of every cloth bag, allows gas sample from dust concentration
Autoprobing machine structure passes through, and when it is greatly exceeded that the dust concentration of gas sample substantially becomes, then dust concentration autoprobing machine structure is automatic
Sound and light signal is sent, while it is damaged which bar cloth bag to be shown automatically through cloth bag number automatic display machine structure again.Above-mentioned technology
When extracting gas sample from every sack of cloth bag, it is necessary to assure probe tube and sampling mechanism move back and forth, sampling method is complicated, unfavorable
In accurate sampling, once go wrong, can't on-bne repair, the influence progress of work.
Utility model content
The purpose of this utility model is on the basis of existing technology, there is provided a kind of on-line automatic leakage detection apparatus of deduster,
Automatically control probe tube and extract the gas sample of every dust-removal cloth-bag of deduster, and by dust concentration detector detectable concentration, realize removing
The on-line automatic leak detection of dirt device, reduces production cost, environmental protection.
To achieve the above object, the utility model uses following technical proposals：
A kind of on-line automatic leakage detection apparatus of deduster, it is characterised in that：
Including probe tube, sample collecting chamber, dust concentration detector and automatic control system；The probe tube is provided with and automatically controls

In dust-removal cloth-bag, probe tube is corresponded and numbered with dust-removal cloth-bag；Sample collecting chamber is connected with the dust concentration detector, collects sample
Room is also associated with air-introduced machine；The automatic control system also includes autoalarm.
The on-line automatic leakage detection apparatus of a kind of deduster of the present utility model, further：Deeply remove the openend of probe tube
10 ~ 20 centimetres of the dust-removal cloth-bag sack lower section of dirt device.
The on-line automatic leakage detection apparatus of a kind of deduster of the present utility model, further：Sample collecting chamber is transparent confinement casing.
The on-line automatic leakage detection apparatus of deduster of the present utility model are so work：When the blowback of deduster stops, inspection
The automatic control system of leakage device starts leak detection, and air-introduced machine is started working, the automatic control of dust-removal cloth-bag corresponding sample pipe to be detected
Valve opening processed, the autocontrol valve of its probe tube is in closed mode, and gas sample, gas are extracted from dust-removal cloth-bag to be detected
, through connecting tube to sample collecting chamber, by the dust concentration in dust concentration detector Detection and Extraction gas sample, detected value is as exceeded setting for sample
Value, illustrates that dust-removal cloth-bag leaks dirt, and autoalarm alarm, staff checks that the numbering of automatic control system just can directly find
Leak-off pocket is directly changed in the dust-removal cloth-bag of specific leakage dirt, shutdown；Detected value then illustrates that dust-removal cloth-bag is intact no more than setting value, continues
Carry out the leak detection work of next dust-removal cloth-bag.Here setting value refers to that dust-removal cloth-bag is complete under deduster stable operation operating mode
When good, the maximum that gas sample dust concentration is obtained in every dust-removal cloth-bag of detection.
Using the utility model, at least have the advantages that：
1st, online leak detection is realized
When being hunted leak to dust-removal cloth-bag using the on-line automatic leakage detection apparatus of deduster of the present utility model, automatically control and be
System control probe tube extracts gas sample from every dust-removal cloth-bag, and the gas sample of extraction is examined through connecting tube to sample collecting chamber by dust concentration
The dust concentration surveyed in instrument Detection and Extraction gas sample.Detected value illustrates that dust-removal cloth-bag leaks dirt, autoalarm report as exceeded setting value
Alert, staff checks that the numbering of automatic control system just can directly find the dust-removal cloth-bag of specific leakage dirt, and shutdown is directly changed
Leak-off pocket；Detected value then illustrates that dust-removal cloth-bag is intact no more than setting value, proceeds the leak detection work of next dust-removal cloth-bag.Can
Specific leak-off pocket position is detected with direct-on-line, is hunted leak one by one without dust-removal cloth-bag is all unloaded, realize online leak detection.
2nd, production cost, environmental protection are reduced
Using the on-line automatic leakage detection apparatus of deduster of the present utility model, can go out leak the dust-removal cloth-bag of dirt with direct detection,
Leak-off pocket need to be directly only changed, it is time-consuming without lot dust-removal cloth-bag is all changed, while realizing that dust-removal cloth-bag is effectively sharp
With reduction production cost, it is to avoid the situation of flour dust overflow occurs when inspection does not measure leak-off pocket, it is ensured that the gas of discharge is dustless dry
Net gas, realizes environmental protection.
