Abstract
The invention discloses a multi-spray-gun water-feeding type tapered annular seam regulating valve, relating to gas scrubbing towers utilized in the process of converter smelting. The multi-spray-gun water-feeding type tapered annular seam regulating valve comprises an outer cone, an inner cone, a valve rod and a hydraulic cylinder, wherein the inner cone is located inside the outer cone and coaxially matched with the outer cone, the upper end of the valve rod is connected with the top of the inner cone, and the lower end of the valve rod is connected with an end of a plunger rod. The multi-spray-gun water-feeding type tapered annular seam regulating valve is characterized in that three to nine spray guns are arranged above a throat of the multi-spray-gun water-feeding type tapered annular seam regulating valve, connected with the outer cone and uniformly arranged along circumference. The invention has the advantages that washing water directly enters from the throat part, therefore, the energy loss of the distance from a spraying point to the throat is effectively avoided when water is sprayed at the top part; and the flow rate of gas in the throat is enhanced in the equal pressure drop, therefore, the dust removal precision is improved.
Description
Technical field
The scrubber that the present invention relates to use in the converter steelmaking process refers to a kind of many spray-gun water-feeding type tapered annular seam regulating valves particularly.
Background technique
The coal gas that produces in the converter steelmaking process reclaims after the scrubber tower dedusting.In the scrubber tower, one of most widely used Venturi tube aditus laryngis equipment for the gas washing dedusting is conical circular seam adjusting valve.The basic principle of conical circular seam adjusting valve is to allow Gas Flow through the narrow annular channel that its internal cones and external cone form, and the flow velocity of coal gas is sharply changed, and catch the purpose that grit reaches dedusting by the mode of water spray.Simultaneously, control the aperture of conical circular seam adjusting valve by the axial distance of regulating internal cones and external cone, and then dynamically control flow velocity and the pressure drop of coal gas.At present, the water spray mode of this valve has two kinds: a kind of is at the top of conical circular seam adjusting valve the hollow cone nozzle to be set, and water is sprayed onto the aditus laryngis of mitre velve in the mode of hollow cone, and this mode is take nippon company as representative; Another kind is at the aditus laryngis position of conical circular seam adjusting valve many tangential intake pipes to be set, intake pipe does not arrange nozzle, water directly flows out from pipeline, tangentially enters aditus laryngis with columned current, and this technology is take Austrian VAI company as representative.
In above-mentioned two kinds of methods, the mode of top water spray is because its injection point is far away apart from aditus laryngis, and spray angle can greatly affect the position that the current particle enters aditus laryngis, and angle is large can be sprayed onto on the external cone, angle is little can be sprayed onto on the internal cones, the difficult control of spray angle.Simultaneously, the water particle of this segment distance fails to be convened for lack of a quorum and causes the loss of larger additional friction from the spray point to the aditus laryngis; Although the aditus laryngis tangent line water pipe water intake mode of VAI can effectively reduce the additional friction loss that above-mentioned current enter aditus laryngis, but because without nozzle, current are to be fractured into fine mist under the dissection of high velocity air after entering aditus laryngis, so the water particle breakage energy is larger, on the other hand, current can be attached on the inwall of external cone under the effect of centrifugal force, and current are also inhomogeneous in the radially direct of aditus laryngis.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of many spray-gun water-feeding type tapered annular seam regulating valves, and not only the loss of the additional friction of its current is little, and the water of ejection can pass through its aditus laryngis equably.
For solving the problems of the technologies described above, a kind of many spray-gun water-feeding type tapered annular seam regulating valves provided by the invention, comprise external cone, internal cones, valve rod and oil hydraulic cylinder, internal cones is positioned at external cone inside, cooperates with external cone is coaxial, the upper end of valve rod is connected with the internal cones top, the lower end of valve rod is connected with the plunger rod end of oil hydraulic cylinder, its specialization is: the aditus laryngis top of described many spray-gun water-feeding type tapered annular seam regulating valves is provided with three to nine spray guns, and spray gun is connected with described external cone and arranges along even circumferential.
In the technique scheme, every described spray gun all is positioned at same plane with valve rod, and the angle α of spray gun and horizontal plane is 45 °.
In the technique scheme, described spray gun comprises gun body, and the head of gun body is provided with nozzle by nozzle carrier; The middle part of gun body is provided with the spray gun mounting flange, is used for being connected with external cone; The afterbody of gun body is connected with intake pipe.
In the technique scheme, described nozzle is the solid-cone spiral nozzle.
Further, the spray angle β of described solid-cone spiral nozzle is 90 °.
In the technique scheme, also be provided with the nozzle guard plate on the described nozzle carrier, the nozzle guard plate is positioned at the nozzle top.
In the technique scheme, described external cone is provided with the ring pipe that is connected with intake pipe, and ring pipe is provided with the flexible pipe that equates with spray gun quantity, and the afterbody of described gun body is connected with corresponding flexible pipe by elbow.
Beneficial effect of the present invention is:
1, scouring water directly enter at the aditus laryngis position, and the energy loss from spray point to this segment distance of aditus laryngis when effectively having avoided the top to spray water under equal pressure drop, has improved the flow velocity of aditus laryngis place coal gas, has improved the dedusting precision;
2, the oblique lower 45 ° of water sprays of spray gun, and spray angle is 90 °, so that the top edge line of spray stream zone is vertical with Gas Flow, the lower limb line is regional and Gas Flow in the same way, water smoke is on average with in the same way 45 ° of angles and Gas Flow collision, obtaining preferably balance aspect the mixing adequacy and energy consumption minimized two, extra energy consumption is low, and dust removal efficiency is high;
3, adopted the solid-cone spiral nozzle, its anti-blocking performance is good;
4, many spray-gun water-feedings have reduced water consumption so that water can enter aditus laryngis along circumferentially and radially evenly distributing, and have improved dust removal efficiency;
5, the spray gun easy accessibility in this device is easy to replace and maintain.
