Description
Technical field
The utility model relates to smoke regulating devices used in a kind of converter steel-smelting flue gas primary dedusting system, belong to
In converter steel-smelting flue gas equipment technical field.
Background technique
With the quickening of rhythm of production, the generation of converter gas amount is consequently increased, and cleaner operating load is also therewith
Increase, the requirement to cleaner is also higher and higher.Circular seam Venturi tube is the fine dust removal equipment in tower text dust pelletizing system, primary
It is played a very important role in gas cleaning and gas recovery system, performance and control precision will have a direct impact on a flue gas
Whether purification and recovery system coal-gas recovering quality and flue gas emission are up to standard, are in converter steel-smelting flue gas process production process
Crucial dust removal installation, the effect of circular seam Venturi tube be by weight adjust aditus laryngis aperture, pass through exhaust gas volumn to reach adjusting
Size, while control fire door flue gas keep micro-positive pressure, guarantee fire door flue gas escape normally, keep flue gas flow rate basicly stable, from
And realize and improve coal-gas recovering quality, reach good dust removing effects.After converter gas is by four sections of cooling stack coolings, into
Enter scrubbing tower and carry out rough dedusting, dusty gas enters circular seam Venturi tube contraction section later, and flow velocity increases, and reaches most when into aditus laryngis
Greatly, the water mist of supply throat is melted into fine drop by such high speed, gas-liquid relative velocity is very big, grit and liquid in gas
Drop is contacted and is wet, so that fierce collision and cohesion occur between grit and drop or grit, into expansion segment, flow velocity is gradually
Reduce, grit is bonded to each other, so that particle is increased and is easily removed, dust removal efficiency is up to 90% herein, it is seen that circular seam Venturi tube is set in dedusting
Importance in standby.In today of environmentally friendly form sternness, quality and the circular seam Venturi tube operation quality of dust removing effects have directly
Relationship.
With the increase of load of dust remove, defect existing for existing circular seam Venturi tube is also gradually displayed, weight with again
Hammer pull rod is attached by flange, and when adjusting aditus laryngis and pulling weight pull rod up and down, the upper end junction of weight pull rod can be due to
Pull rod, which moves up and down, generates very small offset, but the length of weight pull rod is much larger than the length of weight, weight pull rod upper end
It when the minor shifts of generation are transmitted to lower end weight, can cause weight that larger offset occurs due to enlarge-effect, cause weight circle
Circumferential weld between week and two literary tower walls is uneven, so that the dust arrestment rate of circular seam Venturi tube reduces, not only causes release tower flue gas
Discharge beyond standards cause secondary pollution to atmosphere, while stokehold smolders seriously.
Utility model content
The technical problem to be solved by the utility model is to provide one kind can prevent weight deviate circular seam Venturi tube, this
Kind circular seam Venturi tube solves the problems, such as that the circumferential weld between weight circumference caused by deviating as weight and two literary tower walls is uneven, not only
Gas cleaning rate can be improved, can simultaneously be effectively improve the working environment of stokehold.
The technical solution to solve the above problems is:
A kind of circular seam Venturi tube that can prevent weight from deviating, it includes weight, lifter drawing bar, weight and lifter drawing bar position
In in the chamber of circular seam Venturi tube, weight is connected to the lower end of lifter drawing bar, and, there are also guide sleeve, guide sleeve is mounted on circumferential weld text for it
In the chamber of family name's pipe, the central bore of guide sleeve covers the lifter drawing bar periphery above and below weight, in the center of guide sleeve
The body of rod of hole and lifter drawing bar is to be slidably matched, the circumferential distance phase of the inner wall of the central bore and circular seam Venturi tube of guide sleeve
Deng guide sleeve periphery is fixedly connected with the inner wall of circular seam Venturi tube.
The above-mentioned circular seam Venturi tube that can prevent weight from deviating, the guide sleeve are made of guide ring and connecting rod, are oriented to
Ring is annulus, and the diameter of bore of guide ring and the outer diameter of lifter drawing bar match, the inner hole wall of guide ring and lifter drawing bar it is outer
Wall is to be slidably matched, and connecting rod is 4, and connecting rod is horizontal positioned, circumference uniform distribution of the connecting rod along guide ring, the length of connecting rod
Spend equal, the both ends of connecting rod are connected with guide ring and circular seam Venturi tube inner wall respectively.
The beneficial effects of the utility model are:
The utility model respectively adds a guide sleeve above and below weight, and guide sleeve constrains lifter drawing bar,
It prevents lifter drawing bar from the phenomenon that weight shifts occur when pulling up and down, the circumferential weld between weight and two literary tower walls is made to keep equal
It is even.
The utility model structure is simple and convenient to operate, effect stability, solves the difficulty that circular seam Venturi tube weight shifts
Topic avoids the circumferential weld non-uniform phenomenon between weight and two literary tower walls, improves the flue gas trapping rate of circular seam Venturi tube, not only mention
High converter gas purification rate, makes flue gas qualified discharge, alleviates atmosphere pollution, while improving the working environment of blast-furnace man, really
The direct motion of converter producing has been protected, there is significant economic benefit and social benefit.
