Abstract
The utility model relates to a soft dust cleaning system of target, is an intelligent dust cleaning system. Have following characteristics: can monitor the grey thickness that attaches before the regional deashing of each filter bag to use this to start this regional deashing, target deashing promptly for the foundation, regional the remaining of filter bag attaches grey thickness after can monitoring the deashing to with this adjustment deashing intensity, ensure with this that the filter bag surface has certain muffin layer, soft deashing promptly all the time.
Description
Technical field
This utility model relates to a kind of soft soot cleaning system of targeting.
Background technology
Traditional belt cleaner unit is by upper box: cover plate and air outlet by starting form；Middle casing: be made up of porous plate, Filter bag device and Venturi tube；Lower box: be made up of air inlet, ash bucket and inspection door；Dust removing system: be made up of deceleration device and defeated ash, ash exhauster；Injection system: be made up of pulse control instrument, electromagnetic impulse valve, injection tube, gas bag and preventer.When dusty gas is entered ash bucket or unlimited flange port entrance baghouse by air inlet, dusty gas is that purge gas enters clean room through sock filtration, then through clean room's air vent, blower fan drains.Dust amasss the outer surface being attached to filter bag, and is continuously increased, and makes the resistance of sack cleaner constantly increase, and for making equipment resistance less than 1200Pa, bag dust collector can work on, and need to regularly remove the dust on filter bag.Deashing is by pulse control instrument timing sequence starting impulse valve, make bag compressed air (0.5～0.7MPa) be induced the surrounding air (title secondary wind) being several times as much as First air to enter filter bag by injection tube eyelet ejection (title First air) by dedusting skeleton Venturi tube sharply to expand in moment, and the back action along with air-flow shakes off dust, reach the purpose of deashing.
Utility model content
The purpose of this utility model: aim to provide the relatively low soft soot cleaning system of a kind of targeting of a kind of simple in construction, production and use cost and method thereof.
The soft soot cleaning system of this targeting, it would be desirable to the filter bag of deashing is divided into multiple district, it may be assumed that filter bag 1,2,3,4 district；
Arranging piezoelectric transducer in each filter bag district respectively, piezoelectric transducer adopts diaphragm type, fits together with filter bag, and when filter bag attached ash thickness change, filter bag inside and outside differential pressure respective change, filter bag surface configuration also respective change, membrane resistance produces change therewith；
The signal of telecommunication is sent to data processing centre by piezoelectric transducer, is processed by data, obtains filter bag attached ash thickness information；
Data after process are sent to PLC control centre by data processing centre, and when reaching the attached ash thickness set, control centre sends instruction to pulse valve, starts deashing；
After one time deashing completes, a minimal pressure difference signal can be produced, the minimum attached ash thickness of filter bag can be obtained by data processing centre；
Gas tank is provided with pressure transducer, and signal is sent to data processing centre, is controlled the intensity of winding-up by the compression pressure in domination set gas tank；
When minimum attached ash thickness is less than preset value, PLC can pass through flow controller and increase air inflow thus increasing the compression pressure of plenum chamber, and this pressure signal is returned by pressure transducer, otherwise, then reduce air inflow and reduce plenum chamber pressure.
The soft deashing of targeting has the advantage that
1, the pattern that attached ash thickness is deashing condition with filter bag surface avoids the blindness of deashing, is greatly improved the service life of filter bag and pulse valve, reduces deashing energy consumption simultaneously.
2, soft deashing can realize filter bag surface and adheres to certain muffin layer all the time; filter bag can be protected thus being greatly prolonged life of bag filter; can avoid causing dust infiltration filter bag fiber because deashing intensity is excessive simultaneously, cause dust emission concentration to exceed standard, deashing intensity deficiency also can be avoided not reach ash-removal effect.

Detailed description of the invention
This ink jet printer for printing system is further described in detail by we in conjunction with accompanying drawing and concrete example below.
1, the filter bag needing deashing is divided into multiple district, it may be assumed that filter bag 1,2,3,4 district；
2, arranging piezoelectric transducer in each filter bag district respectively, piezoelectric transducer adopts diaphragm type, fits together with filter bag, and when filter bag attached ash thickness change, filter bag inside and outside differential pressure respective change, filter bag surface configuration also respective change, membrane resistance produces change therewith；
3, the signal of telecommunication is sent to data processing centre by piezoelectric transducer, is processed by data, obtains filter bag attached ash thickness information；
4, the data after process are sent to PLC control centre by data processing centre, and when reaching the attached ash thickness set, control centre sends instruction to pulse valve, starts deashing；
5, after a deashing completes, a minimal pressure difference signal can be produced, the minimum attached ash thickness of filter bag can be obtained by data processing centre；
6, plenum chamber is provided with pressure transducer, and signal is sent to data processing centre, is controlled the intensity of winding-up by the compression pressure in domination set gas tank；
7, when minimum attached ash thickness is less than preset value, PLC can pass through flow controller and increase air inflow thus increasing the compression pressure of plenum chamber, and this pressure signal is returned by pressure transducer, otherwise, then reduce air inflow and reduce plenum chamber pressure.
