Abstract
A kind of negative pressure suction apparatus for ash that the high cross-platform dust stratification of pneumatic steelmaking cleans, belongs to environmental protection converter dust-removing technical field.Including compressed air reservoir, gas jet device, the grey hose of suction, across the final dusting pipeline of converter height and pressure reducing valve etc.；There are three access interfaces, respectively compressed air tube inlet, negative pressure ash sucking tube entrance and the outlet of positive pressure ash pipeline for gas jet device；The gas outlet of compressed air reservoir is connected by pipeline with the compressed air tube inlet of gas jet device, has pressure reducing valve in the connecting pipe between compressed air reservoir and gas ejector；The one end for inhaling grey hose is connected with the negative pressure ash sucking tube entrance of gas jet device.The advantage is that structure is simple, is convenient for operation, non-maintaining and long service life, device does not store up ash and transports ash equipment, do not need individually to transport ash, effectively reduce secondary pollution.
Description
Technical field
The utility model belongs to environmental protection converter dust-removing technical field, in particular to a kind of high cross-platform product of pneumatic steelmaking
The negative pressure that ash cleans inhales apparatus for ash.
Background technique
BOF steelmaking shop iron and steel stock, ferroalloy and bulk raw materials disengaging steelshop type are more, and freight volume is big, is steel plant's powder
Dustiness contaminates one of serious place, although now higher and higher to environmental dust removal requirement, environmental dust removal technology and measure is constantly mentioned
It is high and perfect, but all only discharge decrement and post decrement control, it to completely eliminate also unlikely.Cross-platform converter height is more
The building of platform, high workshop, up to 5-7 layers of general large platform, highest podium level is up to 60m.Due to flue dust in converter smelting
Excessive, the feeding of production operation hot metal charging plus steel scrap and bulk raw materials and ferroalloy causes the high cross-platform collection ash of converter in addition
It is more, it such as removes not in time, human body and equipment can be caused to seriously endanger.Common water flushing, compressed air purging or artificial
The methods of cleaning ash disposal, large labor intensity, working efficiency is low, and dust removing effects are poor, also results in secondary pollution.
Chinese invention patent application number 201210502029.0 discloses a kind of vacuum cleaning dust exhaust apparatus, including pocket type removes
Dirt device, cyclone separator, vacuum pipe, the cyclone separator are welded on sack cleaner, the cyclone separator
Be connected by vacuum pipe with the air inlet of sack cleaner, further include Roots vaccum pump, the Roots vaccum pump into
Air port is connected by vacuum pipe with the air outlet of sack cleaner, and the air outlet of the Roots vaccum pump is equipped with noise elimination
Blast cap is installed out in device, the silencer upper end, and the present invention solves is rinsed with water mill floor or compressed air purging in the past
The disadvantage on ground.But the invention equipment is more, Roots vaccum pump needs electricity consumption water, it is also necessary to be regularly maintained, and store grey trolley
The dust of collection also needs specially to transport outward again, and in some places, application is also not very convenient.
Summary of the invention
The negative pressure cleaned the purpose of this utility model is to provide a kind of high cross-platform dust stratification of pneumatic steelmaking inhales apparatus for ash, solution
The high cross-platform collection of converter of having determined is grey more, currently available technology and device not easy cleaning the problem of.Converter height is effectively improved across life
The environment of production mitigates harm of the dust to human body and equipment.
A kind of negative pressure suction apparatus for ash that the high cross-platform dust stratification of pneumatic steelmaking cleans, including compressed air reservoir 1, gas jet
Device 2 inhales grey hose 3, across the final dusting pipeline 4 of converter height, pressure reducing valve 5, ash pipeline 6 and ash suction head 7.Gas jet device 2 has three
A access interface, respectively compressed air tube inlet, negative pressure ash sucking tube entrance and the outlet of positive pressure ash pipeline；Compressed air reservoir 1
Gas outlet be connected by pipeline with the compressed air tube inlet of gas jet device 2, compressed air reservoir 1 and gas ejector
There is pressure reducing valve 5 in connecting pipe between 2；The one end for inhaling grey hose 3 is connected with the negative pressure ash sucking tube entrance of gas jet device 2；
The other end for inhaling grey hose 3 is connected with ash suction head 7；The positive pressure ash pipeline outlet of gas jet device 2 passes through ash pipeline 6 and converter
Across the final dusting pipeline 4 of height is connected.
Present apparatus gas jet device 2 forms local decompression in 2 inner cavity of gas jet device using compressed air injection, passes through suction
Grey hose 3 sucks dust in gas jet device 2, and sucking dust passes through ash pipeline 6 again and is sent into across the final dusting pipeline 4 of converter height
In, the dust of sucking inhales ash with external secondary dedusting system and concentrates discharge.
Utility model has the advantages that
1, ash is inhaled using gas jet device negative pressure, does not need the mechanical vacuums pumping unit such as lobe pump, do not need it is electrical and
Automation equipment, apparatus structure is simple, easy to operate, equipment is non-maintaining, long service life.
2, device does not store up ash and transports grey equipment, does not need individually to transport ash, reduces secondary pollution.The dust of sucking is not required to
It is collected into dedicated ash-storing bin, does not need special equipment toward outward transport ash, but the dust of sucking is sent directly into converter height
In across final dusting pipeline, ash is inhaled with external secondary dedusting system and concentrates discharge.
Detailed description of the invention
Fig. 1 is present apparatus schematic diagram.Wherein, compressed air reservoir 1, gas jet device 2, the grey hose 3 of suction, converter height are across two
Secondary cleaning shaft 4, pressure reducing valve 5, ash pipeline 6, ash suction head 7.
Specific embodiment
Embodiment 1
A kind of negative pressure suction apparatus for ash that the high cross-platform dust stratification of pneumatic steelmaking cleans, including compressed air reservoir 1, gas jet
Device 2 inhales grey hose 3, across the final dusting pipeline 4 of converter height, pressure reducing valve 5, ash pipeline 6 and ash suction head 7.Gas jet device 2 has 3
Access interface, respectively compressed air tube inlet, negative pressure ash sucking tube entrance, the outlet of positive pressure ash pipeline；Compressed air reservoir 1 goes out
Port is connected by pipeline with the compressed air tube inlet of gas jet device 2, between compressed air reservoir 1 and gas ejector 2
Connecting pipe on have pressure reducing valve 5；The one end for inhaling grey hose 3 is connected with the negative pressure ash sucking tube entrance of gas jet device 2；Inhale ash
The other end of hose 3 is connected with ash suction head 7；The positive pressure ash pipeline outlet of gas jet device 2 by ash pipeline 6 and converter height across
Final dusting pipeline 4 is connected.
