Abstract
The invention discloses a kind of fluidized-bed densification stainless (steel) wire cleaning methods, can be convenient and are fast thoroughly cleaned to fluidized-bed multiple dense stainless (steel) wire used in desulfurization composite blowing system.Fluidized-bed is clipped in the middle using two blocks of blind plates, blind plate edge is tightened using bolt, and upside blind plate welds air inlet pipe.Make size water tank appropriate and injected clear water.Fluidized-bed is put into water tank and is impregnated, a small amount of dilute hydrochloric acid (concentration 13% or so) is added and is then passed through compressed air from upside blind plate air inlet pipe is intermittent, liquid stream is washed away to fluidized-bed densification stainless (steel) wire, will thoroughly be blown out after the pulverized limestone being clipped in multiple dense stainless (steel) wire dissolution.
Description
Technical field
The present invention relates to desulfurizing iron fields, and in particular to the cleaning of multiple dense stainless (steel) wire used in blowing pulverized limestone
Dredging.
Background technique
Fluidized-bed shape be it is horn-like, side is uniformly suppressed using multiple dense stainless (steel) wire, and air-flow is from outside
It is uniformly carried out inside cone by fine and close stainless (steel) wire, the lime and magnesium powder that carry out fluidized-bed is fluidized, allowed gas to
Enough uniformly conveying lime and magnesium powder pulvis enter hot metal interior, and pulvis instability of flow is avoided to lead to molten iron splash.If fine and close
Stainless (steel) wire has clogging, gas permeability bad, will affect lime and magnesium powder pulvis fluidisation even results, it may appear that gas conveying
Pulvis instability of flow occurs molten iron splash, leads to metal loss and scaling loss vehicle.
Current cleaning way are as follows: after operating personnel removes fluidized-bed, the high pressure cleaning pump pair for the use of pressure being 30MPa
Fluidized-bed is cleaned, and hydraulic giant carries out cleaning and dredging using high pressure water flow against fine and close stainless (steel) wire.This cleaning way is past
Non-uniform situation is cleaned toward appearance, and fine and close stainless (steel) wire is not easy drying.Once being clipped in the pulverized limestone in fine and close stainless (steel) wire
It does not wash clean clearly, is easy to appear hardened, influence fine and close stainless (steel) wire gas permeability instead.
Summary of the invention
Object of the present invention is to propose a kind of fluidized-bed densification stainless (steel) wire cleaning method, solves high pressure water cleaning and be not thorough
The problem of.
Technical solution of the present invention: a kind of fluidized-bed densification stainless (steel) wire cleaning method makes two blocks of blind plates up and down, and
In side, blind plate installs air inlet pipe additional, and using the big opening end of two pieces of blind plate covering cone fluidized-beds, osculum end, two blocks of blind plates will be bored
Body fluidized-bed is clipped in the middle, and blind plate opens hole, and through-hole passes through for bolt, is fixed two blocks of blind plates tightly with bolt, nut, will be blind
Entirety after plate and the combination of cone fluidized-bed is put into water tank, adds water submerged cone fluidized-bed, it is dense to add 1-2L mass
Degree is the dilute hydrochloric acid of 10-13%, impregnates 10-12 hours, is passed through compressed air from air inlet pipe, gas is stainless by fluidized-bed densification
Liquid in steel mesh is arranged from inside to outside, and after gas all occupies in space in fluidized-bed densification stainless (steel) wire, stopping is passed through pressure
Contracting air ejects the biggish air of pressure in fluidized-bed densification stainless (steel) wire, and water flow is just again from fluidized-bed densification
Stainless (steel) wire penetrates into net, is then passed through compressed air, discharge compressed air again, allows liquid stream to fluidized-bed densification repeatedly
Stainless (steel) wire is washed away, and will thoroughly be cleared out after the lime for being clipped in multiple dense stainless (steel) wire and the dissolution of magnesium powder pulvis, finally will
Cone fluidized-bed takes out from water, ventilates blow out moisture in fluidized-bed densification stainless (steel) wire again, accelerates fluidized-bed
Fine and close stainless (steel) wire is dry, it is ensured that fluidized-bed good permeability.
The air pressure of the compressed air is 0.4MPa-0.5MPa.
Beneficial effects of the present invention: 1, without operating personnel using high pressure cleaning pump (hydraulic pressure 30MPa) fluidized-bed is caused
Close stainless (steel) wire is cleaned, and high pressure water flow is avoided to damage stainless (steel) wire.
2, compressed air drives water flow to be cleaned, dredged more from inside to outside to fluidized-bed densification stainless (steel) wire
It is even, thorough.
3, the fluidized-bed densification stainless (steel) wire rate of drying that cleaning finishes is fast.
Detailed description of the invention
Fig. 1 is the schematic diagram of cone fluidized-bed；
Fig. 2 is fluidized-bed cleaning status diagram.
Specific embodiment
A kind of fluidized-bed densification stainless (steel) wire cleaning method, make up and down two blocks of blind plates 1, and side blind plate weld into
Tracheae 2, covers big opening end, the osculum end of cone fluidized-bed 3 using two blocks of blind plates 1, and two blocks of blind plates 1 are by cone fluidized-bed 3
It is clipped in the middle, hole is opened at 1 edge of blind plate, and through-hole passes through for bolt, with bolt, nut that two blocks of blind plates 1 are fixed tight.Prepare one
The water tank 4 of 3 assembly of blind plate 1 and cone fluidized-bed can be accommodated.Entirety after combining blind plate 1 and cone fluidized-bed 3 is put
Enter in water tank 4, add water submerged cone fluidized-bed 3, adds the dilute hydrochloric acid that 1-2L mass concentration is 10-13%, impregnate 10-12
Hour, be passed through compressed air from air inlet pipe 2, the air pressure of compressed air is 0.4MPa-0.5Mpa, gas by fluidized-bed densification not
Liquid in rust steel mesh is arranged from inside to outside, after gas all occupies in space in fluidized-bed densification stainless (steel) wire, stops being passed through
Compressed air ejects the biggish air of pressure in fluidized-bed densification stainless (steel) wire, and water flow is just caused from fluidized-bed again
Close stainless (steel) wire penetrates into net, is then passed through compressed air, discharge compressed air again, repeatedly allows liquid stream to fluidization repeatedly
The fine and close stainless (steel) wire of bed is washed away, and will thoroughly be cleared out after the lime for being clipped in multiple dense stainless (steel) wire and the dissolution of magnesium powder pulvis,
Cone fluidized-bed 3 is taken out from water finally, ventilates blow out moisture in fluidized-bed densification stainless (steel) wire again, accelerates stream
State bed densification stainless (steel) wire is dry, it is ensured that fluidized-bed good permeability.The volume needs of water tank 4 are sufficiently large, are compressed air
The water slot milling of discharge.
