Description
Technical field
The present invention relates to gas cleaning and dedusting technology field, especially for the device of measuring ash-removal effect of bag-type dust remover.
Background technology
Discharged flue gas contains a large amount of harmful gases in the industrial processes, especially not only contains a large amount of primary particulates in the flue gas that burning produces, and the presoma (SO of secondary pollution
2, organic contaminants such as NOx, heavy metal, palycyclic aromatic) also a large amount of enter atmosphere with flue gas, sack cleaner is an efficient apparatus of administering flue gas.
In the prior art, the method for check sack cleaner operational effect is normally measured the dust concentration of sack cleaner outlet.Its weak point is when carrying out the optimal design of sack cleaner, can't weigh the quality of its ash-removal effect with the dust concentration of this measurement.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the purpose of this invention is to provide a kind of device of measuring ash-removal effect of bag-type dust remover.Its technology is simple, easy to operate, cost is lower, automaticity is high, be easy to promote, be easy to carry.
In order to reach the foregoing invention purpose, technical scheme of the present invention realizes as follows:
A kind of device that is used to measure ash-removal effect of bag-type dust remover, it comprises a plurality of pressure transducers, a plurality of acceleration transducer, data acquisition system (DAS) and computing machine.Filter bag is fixed on the card below.Its design feature is, the input end of described each pressure transducer is arranged in the inboard and the outside of filter bag in pairs, and the input end of each acceleration transducer is fixed on the filter bag outside.Each output terminal to pressure transducer and each acceleration transducer is connected to the high-frequency data acquisition system by data line, and the high-frequency data acquisition system is connected with computing machine by data line.
In said apparatus, the pressure transducer input end of described paired arrangement is arranged closelyer in the filter bag upper and lower, arranges rarelyr at the filter bag middle part.
In said apparatus, the input end of described acceleration transducer is arranged rarelyr in the filter bag upper and lower, arranges closelyer at the filter bag middle part.
In said apparatus, the data line of each pressure transducer of described connection, acceleration transducer and high-frequency data acquisition system is shorter than 10 meters.
In said apparatus, described high-frequency data acquisition system is used the high frequency response capture card.
The present invention compared with prior art has the following advantages and good effect:
(1) pressure transducer and acceleration transducer can truly reflect the motion conditions of filter bag in the deashing process, therefore can truly measure the ash-removal effect of this sack cleaner.
(2) in laboratory study, can on the sack cleaner model, measure the ash-removal effect of designed sack cleaner with the present invention.Intuitive and convenient not only, and saved cost greatly, thus better instruct the design effort of sack cleaner.
(3) technology of the present invention is simple, easy to operate, cost is lower, automaticity is high, be easy to promote and be easy to carry.Be not subjected to time and space constraint, the service efficiency height.
The present invention will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Accompanying drawing is a structure principle chart of the present invention.
Embodiment
Referring to accompanying drawing, the present invention includes the data acquisition system (DAS) 7 and the computing machine 9 of a plurality of pressure transducers 1, a plurality of acceleration transducer 3, use high frequency response capture card.Filter bag 2 is fixed on card 5 belows.The input end of each pressure transducer 1 is arranged in the inboard and the outside of filter bag 2 in pairs, and pressure transducer 1 input end of arranging is arranged closelyer in filter bag 2 upper and lowers in pairs, arranges rarelyr at filter bag 2 middle parts.The input end of each acceleration transducer 3 is fixed on filter bag 2 outsides.The input end of acceleration transducer 3 is arranged rarelyr in filter bag 2 upper and lowers, arranges closelyer at filter bag 2 middle parts.Each output terminal to pressure transducer 1 and each acceleration transducer 3 is connected to high-frequency data acquisition system 7 by the data line 6 no longer than 10 meters.High-frequency data acquisition system 7 is connected with computing machine 9 by data line 6.
The flue gas that is come out by combustion apparatus moves to the outside surface of filter bag 2 by the sack cleaner inlet, because the filtration of filter bag 2, dust forms ash cake at filter bag 2 outside surfaces.Clean flue gas then arrives filter bag 2 inside by filter bag 2, finally is discharged in the atmosphere.During deashing, pressurized air is discharged in the filter bag 2, compressed-air actuated blowback causes filter bag 2 motions.Along with this pulse jet motion, will blow off attached to the ash cake in filter bag 2 outsides, thereby finish deashing process one time.In this deashing process, utilize apparatus of the present invention can measure the ash-removal effect of sack cleaner.
When the present invention moves, pressurized air is released to filter bag 2 inboards, by each situation of change, measure the acceleration of motion of filter bag 2 each positions in winding-up processes simultaneously by each acceleration transducer 3 to the suffered pressure wave in filter bag 2 each positions in the pressure transducer 1 measurement pulse jet process.When one time deashing finished, the motion conditions of the variation of above-mentioned pressure and filter bag 2 reached high-frequency data acquisition system 7 by data line 6, and is stored in the computing machine 9, repeated above-mentioned steps 2 ~ 3 times.9 pairs of above-mentioned measurement data of computing machine are handled and are analyzed, and just can make data evaluation to the ash-removal effect of this sack cleaner.
