Abstract
The utility model relates to the field of maintenance of industrial dust-removing equipment and particularly relates to an online diagnostic device of a cloth-bag dust-removing and ash-cleaning system. The online diagnostic device comprises a PLC (Programmable Logic Controller) control module of the ash-cleaning system, and is characterized by further comprising a displaying instrument and a wind speed sampling probe, wherein the wind speed sampling probe is mounted between a 0# valve and a secondary valve of a back flushing air pipe of the ash-cleaning system; the displaying instrument is mounted in an electric appliance room of the ash-cleaning system and is connected with the wind speed sampling probe; the PLC control module is connected with the displaying instrument through a signal transmission line; after a signal of the wind speed sampling probe enters the displaying instrument, the signal is transmitted into the PLC control module through the signal transmission line. The online diagnostic device disclosed by the utility model adopts the design; after the wind speed sampling probe collect data, the data is transmitted into the PLC control module through the displaying instrument; the cloth-bag dust-removing and ash-cleaning system is diagnosed in real time through pre-stored correlation data of the PLC control module, so that the trouble of stopping the machine to check the cloth-bag dust-removing and ash-cleaning system is saved.
Description
Technical field
The utility model relates to industrial dedusting plant maintenance field, the especially on-line diagnosing apparatus of sack cleaner soot cleaning system.
Background technology
Atmosphere blowback bag-type dust deduster is one of main species of sack cleaner, first and second valve soot cleaning system extensive use on the atmosphere blowback bag-type dust collector.Yet in present routine work, diagnosis is that the equipment downtime situation is carried out, and can only be qualitative can not quantitative Diagnosis, can't find in advance the soot cleaning system fault, can only find after causing certain infringement.
Summary of the invention
The purpose of this utility model is, provides a kind of equipment self-inspection to find fault and can send warnings, improves the on-line diagnosing apparatus of the bag-type dust soot cleaning system of promptness that fault judges and accuracy.
In order to achieve the above object, the utility model is achieved in that
A kind of on-line diagnosing apparatus of bag-type dust soot cleaning system; It comprises the PLC control module of soot cleaning system, also comprises Displaying Meter and wind speed sampling probe; Described wind speed sampling probe is installed between the reverse-blow pipe 0# valve and secondary valve of soot cleaning system; Displaying Meter is installed in the electric apparatus room of soot cleaning system and gives the wind speed sampling probe and connects; The PLC control module is connected with signal transmssion line with real instrument, and the signal of wind speed sampling probe imports the PLC control module into again through signal transmssion line after entering in Displaying Meter.
The utility model adopts above-mentioned design; wind speed sampling probe image data is imported the PLC control module into by Displaying Meter; the correction data that prestores through the PLC control module and in real time the bag-type dust soot cleaning system being diagnosed so can be saved the trouble of shutdown inspection bag-type dust soot cleaning system.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is logic judgement schematic diagram of the present utility model.
The specific embodiment
Below further illustrate the utility model by specific embodiment.
As shown in Figure 1, a kind of on-line diagnosing apparatus of bag-type dust soot cleaning system; It comprises the PLC control module of soot cleaning system, also comprises Displaying Meter and wind speed sampling probe; Described wind speed sampling probe is installed between the reverse-blow pipe 0# valve and secondary valve of soot cleaning system; Displaying Meter is installed in the electric apparatus room of soot cleaning system and gives the wind speed sampling probe and connects; The PLC control module is connected with signal transmssion line with real instrument, and the signal of wind speed sampling probe imports the PLC control module into again through signal transmssion line after entering in Displaying Meter.
Operation principle of the present utility model is as follows:
Blowback design air flow Q=3600KNV/t according to the bag-type dust soot cleaning system; Blowback wind speed v=Q/A/3600; Counter-blowing wind-pressure P=0.5 ρ v2 can determine standard blast, wind speed and the air quantity of bag-type dust soot cleaning system;
Wherein: Q---blowback air quantity, m
3/ h;
N---by certain cloth bag chamber filter bag quantity of deashing;
The volume of V---each filter bag, m
3
K---air leakage coefficient gets 1.2 ~ 1.3;
T---the contracting bag deashing time, generally get 10 ~ 30s;
V---blowback wind speed, m/s;
Q---blowback air quantity, m
3/ h;
The sectional area of A---reverse-blow pipe, m
2
P---blast, kN/m
2];
ρ---atmospheric density [kg/m
3];
V---wind speed [m/s];
Standard blast, wind speed and the air quantity of above-mentioned bag-type dust soot cleaning system are inputted the PLC control module as the standard figures of bag-type dust soot cleaning system, the wind pressure value of the reverse-blow pipe that afterwards the wind speed sampling probe is gathered under filtration condition, blowback state, sedimentation state at the bag-type dust soot cleaning system, air speed value input PLC control module and compare with standard figures, concrete contrast judgement is as follows:
Bag-type dust soot cleaning system filtration condition:
Actual wind pressure value in reverse-blow pipe, air speed value are as less than standard figures, and equipment is normal; Close not in placely otherwise be judged as the secondary valve plate, there is fault in equipment;
Bag-type dust soot cleaning system blowback state:
Actual wind pressure value, air speed value be greater than standard figures in reverse-blow pipe, is judged as the secondary valve plate and closes not in placely, and there is fault in equipment;
Actual wind pressure value, air speed value be less than standard figures in reverse-blow pipe, is judged as valve plate and closes not in placely, and there is fault in equipment;
Bag-type dust soot cleaning system sedimentation state:
Actual wind pressure value, air speed value less than standard figures, are judged as equipment normal in reverse-blow pipe, close not in placely otherwise be judged as the secondary valve plate, and there is fault in equipment.
Wind speed sampling probe image data is imported the PLC control module into by Displaying Meter; the correction data that prestores through the PLC control module; according to above-mentioned judgement relation, can diagnose the bag-type dust soot cleaning system in real time, so can save the trouble of shutdown inspection bag-type dust soot cleaning system.
