Description
Technical field
The utility model relates to steel-making dedusting field, is specifically related to a kind of protective device that is used for adjustable Venturi tube.
Background technology
The pneumatic steelmaking meeting produces the great amount of high-temperature flue gas, need carry out dust removal process to high-temperature flue gas.Existing employing do not fire-and wet type series connection dust collecting process handles high-temperature flue gas.The topmost equipment of said not combustion-wet type series connection dedusting is quick overflow cooling tower and the adjustable Venturi tube of stone roller formula.The high-temperature flue gas that converter produces gets into quick overflow cooling tower through gasification cooling flue under fan action; By nozzle and spray gun to high-temperature flue gas put out a fire, cooling, modified and thick dedusting; The bottom tower body that then gets into quick overflow cooling tower carries out processed, gets into the adjustable Venturi tube of stone roller formula through 180 ° elbow again.
The adjustable Venturi tube of stone roller formula is the second level equipment of converter gas wet dedusting.Its function comprises two aspects, the one, and smart dedusting, the 2nd, coordinate the control of converter mouth place flue gas.The adjustable Venturi tube of stone roller formula is made up of 90 ° of elbows, spray section (undertaking the effect to aditus laryngis spray form water), aditus laryngis section and diffuser four parts; Integral body sees it is a sizing Venturi tube, is referred to as " not moving part ".See that from the formation of the adjustable Venturi tube of stone roller formula the inside core component is to be obconic truncated cone, i.e. stone roller.The top of stone roller connects three sections connecting rods, will cut or polish jade with an emery wheel through them, and the servo hydraulic cylinder of expansion link and Venturi tube topmost is linked to be an integral body, is referred to as " moving part ".By Driven by Hydraulic Cylinder; Stone roller is made movement in vertical direction in certain distance; Thereby change the width of the annulus between conical stone roller and the aditus laryngis, the critical larynx speed of flue gas changes (effect that this is adjustable aditus laryngis), under the effect of water droplets; Fine dust in the flue gas is transferred in the water, and flue gas is by meticulous purification.
The formation of the flue gas of converter is a physical process.Oxidation formed after distillation at high temperature took place metal, and the characteristics of dirt (flue gas) are the visible dust in micron, and micro-dust and submicroscopic dust are carried the part in bulk powder in addition secretly, like Cao, and Cao (OH)
2, dirt has certain magnetic and stickiness." moving part " in the adjustable aditus laryngis is in the encirclement that micro-dust is many flue gas.This type of dust is absolute to the adhesion of " moving part ", continues.When adhering to a certain degree, " moving part " becomes " freezing part ", aditus laryngis by adjustable become non-adjustable.The problem that is associated is, the stroke of stone roller bigger (stroke of driving arrangement is also big), and after being covered, the mobile meeting on the vertical direction of stone roller is difficulty more, and is more insensitive.Become ornaments up to moving part, lose the process function that it should embody.
