Description
Technical field
The present invention relates to restricted clearance inner void upkeep operation fields, make more particularly to a kind of restricted clearance inside aperture
Industry folds cage.
Background technique
Dry method circulating fluidized bed desulfurization technique is in iron and steel enterprise's flue gas desulfurization field using relatively wide, recirculating fluidized bed desulfurization
Technique is recycled in cloth bag-ash bucket-absorption tower-cloth bag system using desulfurizing agent slaked lime powder, with the dioxy in flue gas
Change reaction of Salmon-Saxl and is generated as Desulphurization dust.
Most important equipment first is that absorption tower system in Circulating Fluidized Bed Process.The untreated flue gas being discharged by boiler
Enter from absorb the bottom of the tower.Absorb the bottom of the tower is a Venturi, and speed is accelerated after flue gas flows through Venturi tube, and herein
It is mutually mixed with very thin absorbent powder, severe friction between gas and particle, forms fluidized bed.Spraying into uniform water mist drop
Under conditions of low smoke temperature, absorbent is reacted with the sulfur dioxide in flue gas, and the flue gases of a large amount of solid particles is carried after desulfurization from suction
Top of tower discharge is received, into recycling deduster, the particle being separated is returned through ash bucket, Recycle of material skewed slot to be absorbed
Tower.
Venturi is made of 7 Venturi tubes in dry desulfurization absorbing tower system, and most enterprises application at present follows
When circulation fluidized bed desulfurizing technology, it will appear absorption tower Venturi abrasion condition often, to ensure Venturi tube corrosive wear situation
In controlled range, need periodically to carry out thickness measuring to Venturi tube ontology.It is subsidized if venturi serious wear need to carry out replacement.By
In the Venturi tube risk that may cause personnel when entering venturi intraductal operation and fall higher from absorb the bottom of the tower.To ensure
Flexibility need to use cage to be suspended in Venturi tube when the safety and operation of operating personnel, and operating personnel makees at station in cage
Industry.Due to being limited by absorption tower manhole door size, it is suitble to the cage volume of venturi intraductal operation is excessive cannot be introduced into.
