Abstract
The invention discloses an annular gap long-neck venturi tube. The venturi tube comprises an upper part guide tube assembly (1) and an external cone (3). The upper part guide tube assembly (1) and the external cone (3) are connected. The venturi tube further comprises an internal cone (2) which is matched with the external cone (3). The internal cone (2) extends into the interior of the external cone (3). A central tube (4) is arranged in the internal cone (2). The central tube (4) is a straight tube. The vapor-liquid ratio of the venturi tube is large, there is no elbow tube behind, so that water washing and manual regular cleaning are not needed. Labor cost and time are saved, and yield is increased indirectly.
Description
Technical field
The invention belongs to environmental protection cleaner field, relate in particular to a kind of circumferential weld long-neck Venturi tube.
Background technology
In converter gas purification and gas recovery system, circumferential weld long-neck Venturi tube has concurrently to be regulated tolerance and purifies two kinds of functions of coal gas, is the key equipment of converter gas purification and coal-gas recovering.In the legacy equipment, circumferential weld long-neck Venturi tube back is provided with bend pipe, needs water flushing and artificial periodic cleaning, increases cost of labor and time, has reduced output.
Summary of the invention
Technical problem to be solved by this invention provides a kind of periodic cleaning, circumferential weld long-neck Venturi tube that production efficiency is high of not needing.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of circumferential weld long-neck Venturi tube, comprise top guide pipe combination and outside centrum, the guide pipe combination of described top is connected with outside centrum, also comprise the inside centrum suitable with outside centrum, described inner centrum stretches into described outside centrum inside, and described inner centrum is provided with intervalve, and described intervalve is straight tube.
Also comprise the bottom conduit, described bottom conduit is connected with intervalve, and described bottom conduit is straight tube, and bottom conduit and intervalve coupling part are set with protection tube.
Described bottom catheter jacket is equipped with grease-filled pipe, and can slide in grease-filled pipe.
Described intervalve diameter is 270mm.
The invention has the advantages that, utilize elementary errors to press the aperture of regulating circumferential weld long-neck Venturi tube, just control the size of Venturi tube circumferential weld area, thereby guarantee when exhaust gas volumn changes, the circumferential weld area also and then changes, the flue gas flow rate of control Venturi tube fluctuates in prescribed limit, and resistance is decreased also just control in prescribed limit, thereby guarantees the clean-up effect of Venturi tube and the least energy consumption of blower fan.Circumferential weld long-neck Venturi tube vapour, liquor ratio are big, and the back does not have bend pipe, do not need water flushing and artificial periodic cleaning, save cost of labor and time, have increased output indirectly; Circumferential weld long-neck Venturi tube liquid vapour flow-disturbing is strong especially, and clean-up effect is well more a lot of than conventional " OG " system, can reach 20mg/Nm3, controls at ordinary times about 50mg/Nm3, obviously is better than existing " OG " system.
Description of drawings
Fig. 1 is the structural representation of a kind of circumferential weld long-neck of the present invention Venturi tube;
Mark among the above-mentioned figure is: 1, top guide pipe combination, 2, inner centrum, 3, outside centrum, 4, intervalve, 5, protection tube, 6, the bottom conduit, 7, grease-filled pipe.
The specific embodiment
Fig. 1 is the structural representation of a kind of circumferential weld long-neck of the present invention Venturi tube, comprise top guide pipe combination 1 and outside centrum 3, top guide pipe combination 1 is connected with outside centrum 3, also comprise the inside centrum 2 suitable with outside centrum 3, inner centrum 2 stretches into outside centrum 3 inside, inner centrum 2 is provided with intervalve 4, and intervalve 4 is straight tube.
Also comprise bottom conduit 6, bottom conduit 6 is connected with intervalve 4, and bottom conduit 6 is straight tube, and bottom conduit 6 is set with protection tube 5 with intervalve 4 coupling parts.Be set with grease-filled pipe 7 outside the bottom conduit 6, and can in grease-filled pipe 7, slide.Intervalve 4 diameters are 270mm.
Cooled smoke enters circumferential weld long-neck Venturi tube and carries out smart dedusting, and flue gas is with at a high speed and spray into water droplet collision in the circumferential weld long-neck Venturi tube, grit in the flue gas since diffusion, effect of inertia be combined with the globule cohesion and by except under.
After adopting such structure, utilize elementary errors to press the aperture of regulating circumferential weld long-neck Venturi tube, just control the size of Venturi tube circumferential weld area, thereby guarantee when exhaust gas volumn changes, the circumferential weld area also and then changes, the flue gas flow rate of control Venturi tube fluctuates in prescribed limit, and resistance is decreased also just control in prescribed limit, thereby guarantees the clean-up effect of Venturi tube and the least energy consumption of blower fan.Circumferential weld long-neck Venturi tube vapour, liquor ratio are big, and the back does not have bend pipe, do not need water flushing and artificial periodic cleaning, save cost of labor and time, have increased output indirectly; Circumferential weld long-neck Venturi tube liquid vapour flow-disturbing is strong especially, and clean-up effect is well more a lot of than conventional " OG " system, can reach 20mg/Nm3, controls at ordinary times about 50mg/Nm3, obviously is better than existing " OG " system
By reference to the accompanying drawings the present invention has been carried out exemplary description above; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
