In Fig. 1, arrow represents airflow direction.
Reference: watch-dog 1, dedusting cabin 2, exhaustor 3, filter bag 4, pulse valve 5, injection tube 6, air-purifying chamber 7, dust is dense
Degree on-line computing model 8.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further illustrated.
As it is shown in figure 1, sack cleaner leak-off pocket of the present utility model quickly analyzes inspection system, including dedusting cabin 2, aerofluxus
Pipe 3, at least two filter bag 4 and at least two pulse valve 5, described dedusting cabin 2 top is provided with air-purifying chamber 7, described air-purifying chamber 7
Lower section connects has filter bag 4, the upper end open of described filter bag 4 to be connected with air-purifying chamber 7, and described pulse valve 5 connects injection tube 6,
Connecting in described injection tube 6 has winding-up mouth, described winding-up mouth to be arranged at filter bag 4 upper end, and each pulse valve 5 is correspondingly arranged at least one
Individual filter bag 4, described air-purifying chamber 7 is connected with exhaustor 3, and this alignment system is additionally provided with watch-dog 1, described each pulse valve 5
Being separated by a period of time between winding-up pulse, described each pulse valve 5 is all connected the work recording each pulse valve 5 with watch-dog 1
State, the outlet of described exhaustor 3 is provided with dust concentration on-line computing model 8 with monitoring outlet dust concentration change, described powder
Dust concentration on-line computing model 8 is connected with watch-dog 1, and monitoring result can feed back to watch-dog 1.
The operation logic that this sack cleaner leak-off pocket quickly analyzes inspection system is as follows:
As in figure 2 it is shown, because the winding-up burst length difference of each pulse valve 5, between the winding-up burst length of each pulse valve 5
Being separated by a period of time, therefore the dust concentration of the outlet of exhaustor 3 also presents impulse form change, each pulse valve 5
Winding-up pulse all can be corresponding with a dust concentration change pulsion phase at watch-dog 1.When No. n-th pulse valve 5 corresponding row has broken
When bag or de-bag, the dust concentration change pulse of its correspondence will rise significantly, and so when there is leak-off pocket phenomenon, work people
The pulse valve corresponding to filter bag 4 that member can go wrong according to pulse valve 5 logging and dust monitoring record quick lock in
5, thus only need the filter bag 4 checking this pulse valve 5 correspondence just can find out problem filter bag 4, when cleaner unit runs, filter of can closing
Bag 4 Os Draconis lids, block and arrange approach outside gas stream of pollution, when cleaner unit is stopped transport, can search damaged filter bag 4 and be replaced.
This sack cleaner leak-off pocket is quickly analyzed inspection system and is particularly well-suited to the dedusting that dedusting cabin 2 quantity is many, pulse valve 5 quantity is many
Device, therefore, the quantity of described dedusting cabin 2 is all connected with exhaustor 3 at two or more, the air-purifying chamber 7 of each dedusting cabin 2.And it is every
Individual pulse valve 5 is commonly coupled with 12～15 winding-up mouths, and each winding-up mouth is respectively arranged with the filter bag 4 of correspondence.
Dust concentration on-line computing model 8 may select capacitance method, β ray method, light scattering method, optical absorption method, friction electrical method, surpasses
The dust concentration on-line measurement instrument such as sonic method, microwave method, owing to the Dust Capacity of cleaner unit exhaustor 3 is big, dust stratification is serious, needs
Select a kind of dust stratification also not interfere with the instrument of measuring accuracy, therefore it is preferred that, described dust concentration on-line computing model 8
For electrostatic induction formula dust concentration detector.This instrument uses AC coupled technology, when utilizing dust granules to flow through probe and spy
Dynamic charge sensing between Tou produces signal.Measurement scope 0.01～1000mg/m3, owing to being electrostatic induction formula principle, because of
This detecting head surface dust stratification does not affect measuring accuracy, can reach the non-maintaining purpose of probe.Its principle is as follows:
1. dust quantity (N) * dust Individual Quality (M) is proportional to the quantity of electric charge (Q)；
2. the quantity of electric charge (Q) is proportional to the 4-20mA signal of telecommunication；
3. a dust concentration (mark rice m3In N*M) be proportional to the 4-20mA signal of telecommunication；
4. the most all have any different due to its dielectric constant of dust of different qualities, have plenty of the corresponding big carried charge of big dust,
Having plenty of the corresponding little carried charge of big dust, therefore the relation between we the measured quantity of electric charge and actual dust concentration needs
ISO to be passed through (isokinetic sampling's method) demarcates；
5., after by demarcating, our 4-20mA signal i.e. can be converted into mg/m3Form output.
The verification mode of this system accuracy is as follows: takes up Central Control Room at cleaner unit machine and arranges cleaner unit each branch mailbox body differential pressure
Control dish, once there is leak-off pocket in certain casing of cleaner unit, and this casing differential pressure control dish display differential pressure numerical value is zero, can be with cleaner unit
Leak-off pocket is quickly analyzed inspection system and is mutually authenticated, it is to avoid erroneous judgement.
Certain branch mailbox body is put in leak-off pocket detection and location by branch mailbox body differential pressure control dish, and cleaner unit leak-off pocket quickly analyzes Examined effect
System location is put certain pulse valve and is responsible for the filter bag of winding-up.
Can find in time to change damaged filter bag after this kind of system application, be prevented effectively from the environment answering filter bag damage to be caused dirty
Dye accident.
