Specific embodiment
With reference to embodiment and attached drawing 1-16 the present invention will be further described:
A kind of upper air inlet, lower outlet air dust removal method, air is polluted under the action of blower 8, from cleaner shell 1
The air inlet 2 in portion enters, and through 3 filtration of cartridge filter, is discharged from the air outlet 9 of 1 lower part of cleaner shell, the blower
8 are located at the lower section of filter cylinder 3.Flow direction of the pollution air in cleaner shell 1 is top-down direction.Pollution is empty
Filtration of the dust through cartridge filter 3 in gas, the surface for being attached to filter cylinder 3 cause 3 inside and outside differential pressure of filter cylinder big, work as control system
Sense that pressure difference reaches setting value, it is automatic to start blowback gas bag 5, compressed gas, compressed gas are stored in the blowback gas bag 5
It is sprayed from the jet port 11 of anti-blowpipe 6, bulk gas, which is drawn, when flowing through the confluence ejector pipe 4 with Venturi effect sets into confluence
Ejector pipe 4 simultaneously accelerates to be diffused into filter cylinder 3, and the dust on 3 surface of filter cylinder sheds into ash slot 144 under airflow function, filtering
Pure air afterwards is discharged through air outlet 9.The cleaner includes shell 1, includes contaminant gases in the shell 1
Channel, filter cylinder 3 and clean gas passages, 1 top of shell are equipped with air inlet 2, and lower part is equipped with air outlet 9；The filter cylinder 3 is set
It sets in the inboard of air inlet 2, the outlet of filter cylinder 3 is connected to clean gas passages, and the end of clean gas passages is connected to air-supply
Mouth 9.Blowback system and blower 8 are provided in the clean gas passages.Between the filter cylinder 3 and clean gas passages
Equipped with confluence ejector pipe 4, the blowback system includes blowback gas bag 5 and anti-blowpipe 6, and the anti-blowpipe 6 is equipped with jet port
11, the jet port 11 is located at confluence 4 lower inside of ejector pipe.Pollutant runner mould is equipped in the clean gas passages
Block, the pollutant flow-path module are made of pollutant runner modular structure ontology 14 with outer boxboard 13；The pollutant
Flow-path module structural body 14 includes shape of a saddle top plate 141 interconnected and side plate 142, and the side of the side plate 142 tilts
It is arranged and connects and lead hawk 143, the side plate 142 connects ash slot 144 with the bottom for leading hawk 143；The shape of a saddle top
Blowback gas bag 5 is fixed inside 141 wedge angle of plate, and anti-blowpipe 6 is connected below the blowback gas bag 5, is fixed between the side plate 142
Surface air cooler 7 and blower 8.Setting collects grey vehicle 10 below the ash slot 144.The cleaner connects control system, institute
The control system stated sets and records the running parameter of cleaner, when the running parameter includes the opening and closing of cleaner
Between, automatic shutter parameter, the operating parameter of blower 8 of the electromagnetic valve of blowback gas bag 5.The gas of the pollutant flow-path module
Vibration cleaning device 12 is equipped in body channel.
At runtime, the operating of blower 8 can form negative pressuren zone to present device in equipment cavity, will constantly weld in workshop
Air capture inhalation device to be clean in, air-flow first passes around air return type and enters in equipment cavity from the blinds that hangs down, and a part is dirty
Dye object dust, which hits to fall directly into air return type from the blinds that hangs down, leads ash-pit 144, after filtering of the another part using filter cylinder 3, dust
Particle and weld fumes are blocked or are adsorbed on 3 outside overlay film surface of filter cylinder, and filter cylinder 3 is for 0.3 μm of partial size or more dust
Filter efficiency 99.9% or more, blown by blower 8 through displacement after the ejector pipe 4 that converges by the pure air for entering clean area
9 low wind speed of mouth are uniformly sent to the region away from ground 0.5-2.0m.
When equipment operation for a period of time after, many dusts can be adhered in the outer wall of filter cylinder 3,3 front and back pressure difference of filter cylinder increases
Power consumption increases, and at this moment starts blowback system automatically, carries out reverse gas cleaning to filter cylinder 3, blowback system is mainly by 5 He of blowback gas bag
Anti-blowpipe 6 forms, and when executing blowback, system can control the unlatching of the electromagnetic valve on blowback gas bag 5, due to 6 memory of blowback gas bag
Having pressure is the compressed air of 0.5-0.6MPa, and purge gas can be sprayed from the jet port 11 of anti-blowpipe 6 with supersonic speed, flowed through
When confluence ejector pipe 4 with Venturi effect, mass air flow into confluence ejector pipe 4 and can be accelerated to be diffused into filter cylinder 3 by injection
Cavity in, gas shock and vibration are formed to filter cylinder 3, portion gas reversed can be arranged (by arriving outside filter cylinder 3 inside filter cylinder 3)
Out, the impact and vibration of air-flow can dispose the dust and muffin for being attached to 3 outer surface of filter cylinder, are allowed to fall in and lead hawk 143
And slide and converge in ash slot 144 in two sides, to reach deashing purpose；The air return type being mounted at equipment air inlet 2 at this time
Back draught can be blocked completely from vertical blinds prevents dust from leaking spray unit equipment.The dust being cleaned out passes through unit
Ash slot 144 is converged in the two sides of two sides, is finally pooled in the collection ash vehicle 10 of unit bottom.
3 quantity of filter cylinder of the invention can be odd number or even number, can vertical, inclination or laterally setting.
Above-described embodiment is only used for illustrating inventive concept of the invention, rather than the restriction to rights protection of the present invention,
It is all to be made a non-material change to the present invention using this design, protection scope of the present invention should all be fallen into.
