Abstract
The utility model discloses a circumferential weld long-neck venturi which comprises an upper guide pipe combination (1) and an outer conical body (3), wherein the upper guide pipe combination (1) is connected with the outer conical body (3). The circumferential weld long-neck venturi also comprises an inner conical body (2) matched with the outer conical body (3); the inner conical body (2) is extended into the outer conical body (3); a middle pipe (4) is arranged on the inner conical body (2) and is a straight pipe. The circumferential weld long-neck venturi has a large steam-liquid ratio, and no elbow is arranged behind the venturi, so that water flushing and manual regular cleaning are not needed; the labor cost and the time can be saved; the yield is indirectly improved.
Description
Technical field
The utility model belongs to Environmental-protecting dust-removing apparatus field, relates 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 and regulates tolerance and purify two kinds of functions of coal gas, is the key equipment of converter gas purification and coal-gas recovering.In legacy equipment, be provided with bend pipe after circumferential weld long-neck Venturi tube, need water to rinse and artificial periodic cleaning, increase cost of labor and time, reduced output.
Utility model content
Technical problem to be solved in the utility model is to provide 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 scheme that the utility model adopts 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 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 in grease-filled pipe, slide.
Described intervalve diameter is 270mm.
The utility model has the advantage of, utilize differential pressure to regulate the aperture of circumferential weld long-neck Venturi tube, namely control the size of Venturi tube circumferential weld area, thereby guarantee when exhaust gas volumn changes, circumferential weld area also and then changes, the flue gas flow rate of controlling Venturi tube fluctuates in prescribed limit, and resistance is damaged and is also just controlled at 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 large, after there is no bend pipe, do not need water to rinse and artificial periodic cleaning, save cost of labor and time, indirectly increased output; 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, is controlled at ordinary times 50mg/Nm3 left and right, is obviously better than existing " OG " system.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of circumferential weld long-neck of the utility model Venturi tube;
Mark in above-mentioned figure is: 1, top guide pipe combination, 2, inner centrum, 3, outside centrum, 4, intervalve, 5, protection tube, 6, 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 utility model 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.Bottom conduit 6 is outer is set with grease-filled pipe 7, and can be in the interior slip of grease-filled pipe 7.Intervalve 4 diameters are 270mm.
Cooled flue gas enters circumferential weld long-neck Venturi tube and carries out smart dedusting, and flue gas is with at a high speed and spray into the water droplet collision in circumferential weld long-neck Venturi tube, and in flue gas, grit is because diffusion, effect of inertia are combined cohesion and quilt and are removed down with the globule.
Adopt after such structure, utilize differential pressure to regulate the aperture of circumferential weld long-neck Venturi tube, namely control the size of Venturi tube circumferential weld area, thereby guarantee when exhaust gas volumn changes, circumferential weld area also and then changes, the flue gas flow rate of controlling Venturi tube fluctuates in prescribed limit, and resistance is damaged and is also just controlled at 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 large, after there is no bend pipe, do not need water to rinse and artificial periodic cleaning, save cost of labor and time, indirectly increased output; 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, is controlled at ordinary times 50mg/Nm3 left and right, is obviously better than existing " OG " system
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
